Abstract

The present invention relates to a message delivery method and system, and more particularly to a message delivery method and system in a peer-to-peer independent message delivery group except any network server. The message delivery system includes at least one peer-to-peer independent message delivery group on a network using any kind of communication protocol. The message delivery group is composed of at least one member, wherein the member is independent of any members in other message delivery groups, so the former cannot transmit messages to the latter. The member may be a group subscriber who mainly receives messages, and therefore has the role of a client. On the other hand, the member may be a group manager who mainly transmits individual messages to each group subscriber or bundles of messages to all group subscribers, and therefore has the role of a server.

Description

GROUP-INDEPENDENT MESSAGE TRANSFER METHOD AND SYSTEM
LENDING SPECIFIED APPLICATION MODULE
Technical Field
The present invention relates to a message transfer method and system within a
peer-to-peer independent message delivery group composed of a plurality of computer
systems on a network except any network server.
Background Art
An internetwork is a complex structure in which pluralities of independent
networks are interconnected. And, internetworking is a method for connecting a plurality
of independent networks to a unified structure.
FIG. 1 is a schematic illustration of a general internetwork.
Referring to FIG. 1, a plurality of independent networks such as Ethernet 12, a
Fiber Distributed Data Interface (FDDI) 14 and a Token ring 16, are connected by
internetworking 10.
Users operating within an independent network such as a Local Area Network
(LAN), which is used for delivering data within small area, can utilize a plurality of
different network structures within that specified area at need. For example, Ethernet 12,
token ring 14 or FDDI 16 networks can be used as LAN structures. The Ethernet 12 uses baseband. Also, Ethernet 12 includes a Carrier Sense Multiple Access with Collision
Detection (CSMA/CD) with a 10Mbps band, the Fast Ethernet with a 100Mbps band and
the Gigabit Ethernet with a IGbps band. The token ring 14 transfers a data frame with
information between one computer system and another. The FDDI 16, however, uses a
100Mbps token passing method. Also, it is a LAN with a double ring structure and uses
optical fibers as transfer media.
To give an example of internetworking, one LAN user transfers data to another
LAN user through a Wide Area Network (WAN). In this case, the method for connecting
a LAN to a WAN corresponds to internetworking.
When independent networks are connected with each other for interconnecting,
consideration must be given to a service of each network layer, protocol addresses in each
network, address structures, routing method for data delivering paths and sizes of delivered
data packet.
These days, Internet is prevalent. The Internet connects independent networks all
over world for the purpose of delivering one network user's data to another network user at
a great distance. Transmission Control Protocol/Internet Protocol (TCP/IP) is based on
the Internet having a plurality of hosts, which have unit networks and individual IP
addresses attached to the unit networks. Moreover, the Internet is a communication
network capable of delivering data via independent networks such as a Public Switched
Telephone Network (PSTN). An IP layer is a network layer, specifically, the 3rd layer in a 7 layer Open System
Interface. The IP layer takes charge of connecting the dependent and the independent
parts of the network. An IP address is a unique address on the Internet. Each IP address
is generally 32 bits. It can be divided into a part identifying a subnet within Internet and a
part identifying a host on the subnet.
A network model for interconnecting users may be a centralized processing model,
a client/server model or a peer-to-peer model. A peer-to-peer model interconnects users
privately.
The centralized processing model used for the first network model provides high
processing speed, fault tolerance and security for connections between a host and terminals.
The host receives a query from at least one terminal about work-related operation data,
supports data integrity and is in charge of security for excluding unauthorized users. Thus,
related tasks between the host and terminals are cannot be almost worked. However, it is
difficult to change the structure of networks based on the centralized processing model.
Consequently, there are problems resulting from delays for servicing. Also, if a personal
computer (PC) is used as a terminal device, a micro computing environment does not
provide data integrity and security in data processing. However, because this network
model has several advantages not existing in the terminal devices, a client/server model is
disclosed.
The client/server model is mainly used on the Internet and makes possible the shared use of resources.
FIG. 2 is a schematic illustration of a general client/server model.
Referring to FIG. 2, in the client/server model, a server 20 stores data in a database
21, and clients 22, 24 and 26 request and display the data. Therefore, processing
operations are divided into back end operations by the server 20 of storing and providing
data and front end operation by clients 22, 24 and 26 of requesting specified data. If the
clients 22, 24 and 26 transmit a query requesting data to the server 20, the server 20
searches for the data in the database 21, performs the requested operation and provides the
results to the clients 22, 24 and 26 through the network.
In this client/server model, the server 20 is always waiting for queries from the
clients 22, 24 and 26. The clients 22, 24 and 26 transmit request signal to connect with
the server 20. Therefore, the server 20 and clients 22, 24 and 26 have different roles.
Moreover, the server 20 and clients 22, 24 and 26 are independent from hardware. That is,
the server 20 must provide same services to the clients 22, 24 and 26 regardless of the
Operating System (OS) or hardware used. Also, the entire system in the client/server
model must not be influenced by the scale of the model according to the number of the
server 20 or clients 22, 24 and 26.
An Internet user can hold a video-conference and can exchange data with any other
user at any location. Moreover, the user can utilize electronic mail (e-mail) or messenger for delivering letters or messages to other users. In addition, the user can provide text,
image or moving picture data to any other user via a web server, and can search for desired
information on the Internet, which is called a sea of information.
With the client/server module, a user can transmit messages and e-mails to other
users coupled to a message server or a mail server. A sender for transmitting data sends
messages to a receiving server coupled to a recipient via a transmission server and the
recipient then receives message from the receiving server.
FIG. 3 is a schematic illustration of the procedure for delivering e-mail from one
user to another based upon a server.
Referring to FIG. 3, users 32 and 38, who wish to transmit and receive e-mail, are
coupled to mail servers 34 and 36 respectively. The mail servers 34 and 36 include a Post
Office Protocol (POP) server and a Simple Mail Transfer Protocol (SMTP) server, which
are used to transmit and receive the e-mail sent back and forth between the users 32 and 38.
The mail servers 34 and 36 are interconnected via the Internet.
The POP is a protocol for receiving e-mail. The POP server and more advanced
POP2 server utilize Port 109 of a TCP session. The more recent and much-used POP3
server utilizes Port 110. The SMTP server is a server for transmitting e-mail and is
located in the application layer. The SMTP server utilizes a TCP session for safe
transmission of e-mail. FIG. 4 is a schematic illustration of the procedure for delivering e-mail when a
sender transmits the e-mail to a recipient through mail server.
Referring to FIG. 4, if a sender 32 makes and sends an e-mail to the mail
transmission server 34, the mail transmission server 34 stores the e-mail of the sender 32
and transmits the e-mail to the mail-receiving server 36 through the SMTP server. For
transmitting the e-mail through a plurality of routers on the Internet, the mail transmission
server 34 uses an IP address of the mail-receiving server 36 connected to the recipient 38.
The mail transmission server 34 can give different priorities to each user according to their
specified level. It can also store and transmit bulk mail, which has a volume up to a
specified size. Thus, there are many cases in which an e-mail written by a user can take a
long time to be transmitted from the mail transmission server 34 to the destination server.
The e-mail can take the shortest course or travel around through many routers. The time
required for transmitting e-mail to the mail-receiving server 36 is generally 500 about
milliseconds. When an e-mail arrives at the mail-receiving server 36 via the SMTP server,
the mail-receiving server 36 provides the e-mail to the recipient 38 via the POP3 server.
The time required to route the received e-mail from the SMTP server to the POP3 server
ranges from 30 seconds to a few minutes. The recipient 38 can check the received e-mail
using a mail application through the POP3 server. The time interval of check for the
received e-mail from the sender 32 can be altered according to the recipient's settings in their mail application.
Therefore, the time required for transmitting e-mail from the sender 32 to the
recipient 38 can be influenced by the sender's specified priority in the mail transmission
server 34, delivery time and the routing time in the mail-receiving server 36. So, the
recipient 38 can receive e-mail from the sender 32 from several minutes to a few days.
Ultimately, it is difficult to transmit messages rapidly and accurately using the client/server
model. The client/server model is especially undependable for transmitting urgent news
and information about stocks.
A message transfer system with a server includes a Master Control Program (MCP)
for controlling message transfer between resources connected to a network. Because mail
server, which controls the transmission of the e-mail, transfers messages by means of the
MCP, the MCP acts as a gatekeeper supporting timing, routing and compatibility among
the independent networks. Thus, the MCP is necessary for communication among a
plurality of resources. Moreover, the server needs an Operating System (OS); however,
an OS for the PC such as windows 98 cannot be used by a server.
Therefore, a server acting as a gatekeeper cannot guarantee the security of
messages or data, because it only manages the delivery of data among clients.
On the other hand, a peer-to-peer model can provide a method for delivering
messages or data via a direct path among users except a server. FIG. 5 is a schematic illustration of a peer-to-peer model.
Referring to FIG. 5, in the peer-to-peer model, data and messages are delivered via
a direct path between computer systems 52 and 54 except a server. That is, computer
systems 52 and 54 process the transmission or receiving of messages on the same level.
Generally, a computer system with large storage capacity and efficient computation ability
is required as a server because the client/server model serves more than ten users located in
different places. However, a peer-to-peer network called workgroup provides the same
service to less than ten users. Public level security is used most frequently in peer-to-peer
network security. A password is required for accessing a specified directory, file and
resource such as a printer.
If computer systems are interconnected in a peer-to-peer network, the delivery time
for mail or messages is decreased to less than 500 millisecond because of the reduction in
the routing time via the POP or SMTP server. The loss of mail or messages in the
delivery process can also be avoided. For these reasons, peer-to-peer models have been
widely used for interconnecting computer systems of users within the same area in LANs.
The peer-to-peer model can provide greater speed, dependability and security in
data and messages transmission than the client/server model. However, two
disadvantages of peer-to-peer model are their low efficiency in data delivery and difficulty
in managing individual users, because of the hardness for integrating management of the
users owing to user's individual management. Recently, Internet service is widely used that interconnects a plurality of users
within peer-to-peer network and direct delivery of the message and data among the users.
Two representative services are Napster and Soribada.
The Napster program produced by Napster Co. is for linking users connected to the
Napster server. The Napster server searches a user's information and mp3 files in a
connected computer system and provides a list of user and mp3 files for other users.
Thus, a user with a Napster program can access the information and mp3 files of other
users in real time. The Napster server just provides a list of a user's information and mp3
files except storing any mp3 files.
A user who wishes to access messages or mp3 files connects directly with another
user's computer system using its IP address. Thus, a user can exchange messages or
desired data with other users while bypassing the Napster server.
That is, if a user selects another user of the Napster program to connect with, those
users can exchange messages and data in real time by means of a direct peer-to-peer type
of connection between them. The Napster program is provided at the Napster web site
www.napster.com.
The Soribada program is similar to the Napster program. When users are
authorized to access the Soribada web server, messages and data are exchanged among
users by means of the Soribada program in real time. The Soribada program is provided
at the Soribada web site www.soribada.com. FIG. 6 is a schematic illustration of the procedure for delivering messages or data
used by the Napster and Soribada programs.
Referring to FIG. 6, users 62 and 64 connect with a server 60 through the Internet.
Then, users 62 and 64 can search a list containing IP addresses and information of other
users connected to the server 60. The users 62 and 64 can each open his/her directory for
mp3 files, image data or other data that other users might search for. Thus, a user can
search through any other user's information, select at least one item from the list of users
and directly couple to the selected user using his/her IP address while bypassing the server
60. After a connection between users is established, messages and data are exchanged
directly from one user to another.
For the sake of user's searching for the list of another user connected to the server
60, the server 60 maintains session with each user 62 and 64. Thus, each user 62 and 64
can search another user's connection to the server 60. Generally, the server 60 utilizes
1Mbyte for the maintenance of session with user respectively. Therefore, necessary
memory size in the server 60 is increased in accordance with number of users connected to
the server 60. If large number of users is connected to the server 60 simultaneously, data
processing speed of the server 60 will be decreased.
The above network model is to combine the client/server model and the peer-to-
peer model and is a method for delivering message and data through the direct path between specified users after authentication for the users coupled to the server. The
above network model limits the service into the users with authorized IP address. Thus,
some users using proxy server or private IP address in the LAN cannot use the above
network model. The private IP address expressly provided in the REC 1918 is a
designated address block for using freely in the local area. Particularly, the private IP
address is composed of 3 blocks; the first block is from 10.0.0.0 to 10.255.255.255, the
second block is from 172.16.0.0 to 172.31.255.255 and the third block is from 192.168.0.0
to 192.168.255.255.
However, above model such as Napster or Soribada service needs a server to form
at least one group for delivering message or data. This model cannot also support the
security among the users because each user must couple to the server.
Also, since the time for delivering message or data via POP server or SMTP server
is changed by the priority of user, some users dealing urgent problems cannot satisfy the
delivering service.
Moreover, when a user intends to communicate with other user using different
language, it is difficult for the users to deliver the message to the other user. Thus, it is
fact that message delivery is not easy since the user must consider a language of the other
user.
Also, since the prior message transmission systems are limited to the field for
delivering test or simple message, they do not include function of document management such as word processing or utilization of other applications.

Best Modes for carrying out the Invention
Hereinafter, preferred embodiments of the present invention will be described in
more detail with reference to the accompanying drawings.
The present invention intends to provide a message delivering method and system
that could be usable in the field demanded rapidness and correctness for delivering data
such as stock information, prompt report and press news. Also, the present invention
makes message to deliver quickly and correctly in the group for uniform working, for
example, a group based on a doctor that transfers prescription of the doctor to a pharmacist
or a nurse in the group.
Therefore, in the present invention, users are interconnected in the form of peer-to-
peer so that the user's computer system may have a role of server or client except any web
server relaying the message. Also, the user can perform independent message delivery
group in terms of assigning at least one other user connected to himself as group subscriber.
Because the user can constitute such a message delivery group voluntarily, one user can be
a group subscriber in a message delivery group simultaneously with group manager in
another message delivery group. Thus, a group manager can transmit the message to each
group subscriber in the same message delivery group at high speed nearly in real time and he can receive the message as group subscriber in another message delivery group from the
group manager of that.
Moreover, since the message delivery system of the present invention includes a
translation module for each national language, when the received message does not
correspond to the receiver's language, the message is translated and displayed in the form
of receiver's language by accessing the translation module automatically.
Also, the message delivery system of the present invention transfers text message
in the form of American Standard Code for Information Interchange (ASCII) code for
transmitting message at high speed. In order to chat and document process additionally,
the message delivery system lends the corresponding module instantly in accordance with
the request from the user, transforms the message or document to binary or ASCII code
and transmits that. Therefore, because the receiver can recognize the message or
document in the form of binary or ASCII code using the corresponding module, the
message delivery system can use diverse function at high transfer speed.
FIG- 7a is a schematic illustration of a group-independent message transfer system
in accordance with one preferred embodiment of the present invention.
Referring to FIG. 7a, the group-independent message transfer system performs
peer-to-peer connections among the users 70, ... , and 78. It is preferred to use IP
addresses of the each user's computer system for connecting the users 70, ... , and 78 except any message server. Each user 70, ... , and 78 can select other user intended to
connect.
For a group subscriber connects to a group manager to transmit message to him,
the group manager must approve the connection. When a group subscriber requires a
connection to the group manager, owing to an offer of an IP address from the group
manager and approval for entrance to the message delivery group, the group subscriber can
be included to the message delivery group. Thus, it is possible to support a complete
security between the group subscriber and group manager. It is also possible for the
group manager to transmit message at high speed to the remote group subscriber for the
one-to-one connection in the same message delivery group.
For example, such as FIG. 7a, a message delivery group GI includes user A 70,
user B 72, user C 74 and user D 76 as group members. The user A 70 as a group manager
acting as a server in the message delivery group GI makes a message transmitted to the
group subscribers 72, 74 and 76 acting as a client in the message delivery group GI after
the message is copied sequentially. That is, each group subscriber 72, 74 and 76 in the
message delivery group GI has a one-to-one connection respectively to the group manager
user A 70.
Generally, when the group subscribers 72, 74 and 76 connect to the group manager
70 in the message delivery group GI after the group GI is generated, the group manager
70 maintains session with the group subscribers 72, 74 and 76 until they 72, 74 and 76 remove the connection. Normally, 1Mbyte memory size is used per one session for
maintaining the session between the group manager 70 and group subscribers 72, 74 and
76. Therefore, message processing and transmission speed is decreased in accordance
with increasing the number of group subscribers 72, 74 and 76 connected to the group
manager 70.
To overcome the above problem, in the case of connection request from the group
subscribers 72, 74 and 76, the group manager 70 acting as a server in the message delivery
group GI ascertains whether the group subscriber is a group member and approves a
connection according to the result. After approval of the connection, the group manager
70 recognizes the IP addresses of the group subscribers 72, 74 and 76, stores them in the
storage space and then closes the session for connecting to the group subscribers 72, 74
and 76. Thus, the group manager 70 does not use memory space for maintaining the
session after approval of the connection. And then, the group manager 70 directly
transmits message to the group subscribers 72, 74 and 76 in the message delivery group GI
using IP addresses of them 72, 74 and 76. It is preferred to attach IP address of the group
subscribers 72, 74 and 76 and flag bit for checking the correct transmission to the message.
Therefore, each user can play a role of a server as a group manager in a message
delivery group and can simultaneously play a role of a client as a group subscriber in
another message delivery group. FIG. 7b is a schematic illustration of computer construction as server or client in a
group-independent message transfer system in accordance with one preferred embodiment
of the present invention.
Referring to FIG. 7b, the group-independent message transfer system of the
present invention may include users SI, ... , and S4 for transmitting message as group
managers with a role of server, users Cl, ... , and C7 for receiving message as group
subscribers with a role of client and users S/Cl, ... , and S/C3 with both roles of group
manager and group subscriber.
Each users SI, ... , and S4 transmits message to at least one group subscribers
S/Cl, ... , and S/C3 in the message delivery group formed by himself. Thus, the users SI,
... , and S4 can receive message from another group manager because they do not belong
to another message delivery group. However, they can receive message from the group
subscriber in the same message delivery group through the one-to-one connection.
Each users Cl, ... , and C7 as group subscriber plays a role of client who receives
message from the group manager in the message delivery group of himself. Thus, the
user does not transmit a bundle message - it is not one-to-one communication but
distributed message for plurality of users - to the users in another or same message delivery
group, but receives message transmitted from the group manager.
On the other hand, each users S/Cl, ... , and S/C3 playing both role of the group
manager and group subscriber transmits message to the group subscribers Cl, ... , and C7 in the message delivery group and receive message from the group managers SI, ... , and
S4 in his message delivery group.
In consequence, a user in the group-independent message transfer system of the
present invention can be a position of the group manager, group subscriber or both the
position.
The group managers SI, ... , and S4 can have a position of the group subscriber in
accordance with subscribing to another message delivery group such as dotted arrow.
The group subscribers Cl, ... , and C7 can also have a position of the group manager by
forming other message delivery group any time.
FIG. 8 is a flow chart illustrating message transmitting/receiving process in the
same message delivery group in accordance with one preferred embodiment of the present
invention.
Referring to FIG. 8, a group subscriber requests a connection to the group manager
in the message delivery group (s2). For the sake of requesting connection from the group
subscriber to the group manager, the group subscriber must be entered to the corresponding
message delivery group. The entrance for the message delivery group will include
processes of group subscriber's connecting to the group manager, providing his IP address
and user information, and registering as a member in the message delivery group. FIG. 9a is an illustration of recording process of user information for entering the
message delivery group in the group-independent message transfer system in accordance
with one preferred embodiment of the present invention.
Referring to FIG. 9a, a user who wishes to enter a specified message delivery
group registers as a group subscriber using a program capable of delivering message in his
computer system. The contents for registering may be composed of a user's ID, password,
an IP address of a group manager acting as a of server in the message delivery group, a
user's name, joint information (number of phone or mobile phone) and an e-mail address.
When the user requests entrance of the selected message delivery group by registering the
user's information, the user's information is transmitted to the group manager of the
message delivery group together IP address of the user. Thus, the group manager can
determine the entrance for the user to the message delivery group according to the user's
information who wishes to enter the message delivery group.
A group subscriber can enter one or more message delivery groups. A plurality
of group registration window is displayed in the computer system in case of the user
intends to enter a plurality of message delivery group.
A group manager acting as a server in the message delivery group can ascertain
the group subscriber's information entered as member of the message delivery group
according to the process of registration. FIG. 9b is an illustration of controlling process for the message delivery group by
the group subscriber entered as a member of the message delivery group in the group-
independent message transfer system in accordance with one preferred embodiment of the
present invention.
Referring to FIG. 9b, after the user enters the message delivery group such as FIG.
9a, the group subscriber can manage the information of his entered message delivery group
displayed in the screen.
The information of the message delivery group entered by the group subscriber
may be composed of a group manager's name and IP address, ID and password having
used in the process of entering message delivery group by the group subscriber.
Preferably, the group subscriber can determine whether he receives message or not from
each entered message delivery groups and can change specification of another group
subscriber. And, the group subscriber can confirm his connected group presently among a
plurality of message delivery groups.
FIG. 10 is an illustration of confirming process for the registration information and
connection state of the member entered message delivery group by the group manager
acting as a server.
Referring to FIG. 10, the group manager acting as a server in the message delivery
group can ascertain information of the group subscriber in the message delivery group. As it were, ID, password, name, connecting line (phone number or mobile phone), e-mail,
connection statistics and IP address of the group subscriber transmitted from the user as a
group subscriber in the process of subscribing are displayed in the screen. And, the group
manager can ascertain the group subscriber being connected at present. The group
manager can ascertain the IP address of the group subscriber, because it is transmitted to
the group manager together a subscription request in the subscription to the message
delivery group. Thus, the group manager can ascertain the member receivable the
message promptly when the group manager transmits a message to the group subscriber in
the message delivery group.
When the group subscriber requests a connection, the group manager ascertains
whether the group subscriber is a group member of the message delivery group using the
IP address, ID or name of the group subscriber. The group manager authenticates the
connection request if the group subscriber is a group member of the message delivery
group (s4). When the authentication for the connection is completed, a session between
the group manager and group subscriber is closed (s8) after the IP address of the group
subscriber having requested the connection is stored in the buffer of the group manager
(s6) in order to decrease the used memory size and prevent the reduction of the message
transmission speed. Because the group manager does not use other memory for
connecting to each group subscriber in state of the session close, speed for transmitting and
processing the message is not reduced although lots of group subscribers connect to the group manager.
On the other hand, in order to intensify the security of the IP address between the
group manager and group subscribers belong to the same message delivery group,
cryptography can be used for delivering IP address. The IP address composed of 0 ~ 9 is
encoded to alphabet or special symbol and the alphabet or special symbol instead of the IP
address is transmitted. It is possible to intensify the security of the IP address in
accordance with being decoded the alphabet or special symbol to the numeric, which
means the IP address, by the receiver.
The group manager makes a message for transmission to the group subscriber in
the message delivery group, abstracts the IP addresses of the group subscribers in
connection state from buffer, and transmits the message to each group subscriber
simultaneously (sl2). Thus, the group subscribers 72, 74 and 76 in one message delivery
group (GI) receive the message transmitted from the group manager 70 at almost same
time.
When the group manager 70 takes responses of the reception (sl4) meaning for the
correct delivering from each group subscribers 72, 74 and 76, the sessions between the
group manager70 and group subscribers 72, 74 and 76 are closed (sl6). On the other
hand, the group manager needs to know whether the group subscriber confirms the
message or not. Thus, when the group subscriber confirms the message transmitted from
the group manager, the group manager can know the group subscriber's confirmation for the message by the message confirming signal from the group subscriber (sl9).
Except the message transmitting from the group manager 70 to the group
subscribers 72, 74 and 76 by one side, it is possible to transmit the message from the group
subscribers 72, 74 and 76 to the group manager 70 in a message delivery group GI. Thus,
the group subscribers 72, 74 and 76 can only connect to the group manager 70 by one-to-
one and cannot manage the other group subscriber in the message delivery group GI.
In the message delivery system of the present invention, the group manager can
form a message delivery group and transmitting the message to the group subscriber with a
general computer system using windows series as OS.
FIG. 11 illustrates a computer system that group manager or group subscriber can
use in the message delivery system of the present invention.
Referring to FIG. 11, a computer system 100 of the group manager or group
subscriber includes a memory system 110, at least one high speed Central Processing Unit
(CPU) 120 in conjunction with the memory system 110, an input device 130 and an output
device 140.
The CPU 120 includes an Arithmetic Logic Unit (ALU) 122 for performing
computations, a collection of registers 124 for temporary storage of data and instructions,
and a control unit 126 for controlling operation of the computer system 100. The CPU
120 may be a processor having any of a variety of architectures including Alpha from Digital, MIPS from MIPS Technology, NEC, IDT, Siemens, and others, x86 from Intel and
others, including Cyrix, AMD, and Nexgen, and PowerPC from IBM and Motorola.
The memory system 110 generally includes high-speed main memory 112 in the
form of a medium such as Random Access Memory (RAM) and Read Only Memory
(ROM) semiconductor devices, secondary storage 114 in the form of long term storage
mediums such as floppy disks, hard disks, tape, CD-ROM, flash memory, etc. and other
devices that store data using electrical, magnetic, optical or other recording media. The
main memory 112 also can include video display memory for displaying images through a
display device. Those skilled in the art will recognize that the memory system 110 can
comprise a variety of alternative components having a variety of storage capacities.
The input and output devices 130 and 140 also are familiar. The input device 130
can comprise a keyboard, a mouse, and a physical transducer (e.g., a touch screen or
microphone), etc. The output device 140 can comprise a display, a printer, and a
transducer (e.g., a speaker), etc. Some devices, such as a network interface or a modem,
can be used as input and/or output devices.
As is familiar to those skilled in the art, the computer system 100 further includes
an operating system and at least one application program. The operating system is the set
of software that controls the computer system's operation and the allocation of resources.
The application program is the set of software that performs a task desired by the user,
using computer resources made available through the operating system. Both are resident in the illustrated memory system 110.
In accordance with the practices of persons skilled in the art of computer
programming, the present invention is described below with reference to acts and symbolic
representations of operations that are performed by computer system 100, unless indicated
otherwise. Such acts and operations are sometimes referred to as being computer-
executed and may be associated with the operating system or the application system as
appropriate. It will be appreciated that the acts and symbolically represented operations
include the manipulation by the CPU 120 of electrical signals representing data bits which
causes a resulting transformation or reduction of the electrical signal representation, and
the maintenance of data bits at memory locations in memory system 110 to thereby
reconfigure or otherwise alter the computer system's operation, as well as other processing
of signals. The memory locations where data bits are maintained are physical locations
that have particular electrical, magnetic, or optical properties corresponding to the data bits.
Each user can constitute the message delivery group voluntarily. FIG. 7
illustrates the case of 3 message delivery groups GI, G2 and G3. In message delivery
group GI, a user A 70 plays a role of a server as group manager and user B 72, user C 74
and user D 76 play roles of clients as group subscribers. In message delivery group G2,
the user C 74 is a group manager and the group subscribers for receiving the message
transmitted from the user C 74 are the user A 70 and user E 78- Also, the message
delivery group G3 is composed of a user B 72, user D 76 and user E 78. The user E 78 is a group manager and, the user B 72 and user D 76 are group subscribers. Furthermore,
each users 70, ... , and 78 can constitute at least one message delivery group and manage
each group. Thus, the user acting as a group manager can transmit different messages to
each message delivery groups.
FIG. 12 is a flowchart illustrating group-independent message transfer method in
accordance with preferred embodiment of the present invention.
Referring to FIG. 12, a group subscriber selects a group manager for transmitting
message independently and requests entrance as a member of the message delivery group
in accordance with connecting to the selected the group manager. After the entrance to
the message delivery group is authenticated by the group manager, the group subscriber as
a member of the message delivery group can receive message transmitted from the group
manager. In order to subscribe as a member of message delivery group, a group
subscriber inputs IP address of a group manager on a message-delivering program installed
in the computer system and transmits ID, name or IP address to the group manager. So,
the group manager puts the ID, name or IP address of the group subscriber in his message
delivery group.
In the state of subscription to the message delivery group, the group subscriber
requests a connection to the group manager in peer-to-peer using the IP address of the
group manager except any message transmission server (s20). The group manager discriminates whether the group subscriber requesting connection to the group manager is
a member of the message delivery group or not using the ID, name or IP address of the
group subscriber (s22). If the group subscriber is a member of the message delivery
group (s24), the IP address of the group subscriber is stored in the buffer and included in
the present connection list, and session between the group subscriber and group manager is
closed (s26). To close the session between the group manager and group subscriber like
above is reason to decrease the memory size used for maintaining the session and prevent
reduction of the processing speed caused by the connection of the group subscriber
because the message is transmitted directly through the IP address of the group subscriber.
If the group manager intends to transmit a message to a plurality of group
subscribers in the message delivery group (s28), the message manager transmits the
message each group subscribers in the message delivery group using the IP addresses
stored in buffer by opening the session after completion of the message (s30). The
message delivery groups are interconnected in the form of peer-to-peer. Thus, it is
possible to rapidly transmit message since routing time via message transmission server is
unnecessary. Therefore, high-speed and security for transmitting the message can be
accomplished in field of data delivering such as stock quotation which is fluctuated in a
few seconds.
On the other hand, it is preferred to transmit the message together check bit for
confirming message arrival or error of the transmission process after transmission of the total message is completed, because transmission confirmation for each data packet
increases the time for transmitting total message. Thus, the message can be retransmitted
to the group subscriber, which does not receive the message correctly or has an error for
transmission, by using check bit (s34). If the message is not retransmitted, the message
can be transmitted to the mobile terminal of the group subscriber through Simple Message
Service (SMS) server.
Otherwise, if the group subscriber uses flouting IP address or private IP addresses,
which ranges from 10.0.0.0 to 10.255.255.255, from 172.16.0.0 to 172.31.255.255, and
192.168.0.0 to 192.168.255.255, it is impossible to transmit the message to the group
subscriber using the IP addresses.
In this case, checking the existence of the message for the group manager at each
regular time interval, the group subscriber can take the message from the group manager
when the message is existed. Thus, the group manager only ascertains the group
subscriber in the message delivery group, needless to store the IP address of the group
subscriber in buffer.
Otherwise, it will be possible to transmit message to user using flouting or private
IP address through a cache server equipped to a router on network such as U.S. Pat. No.
6,167,438. Also, transmitting the private IP address together authorized IP address of
router or server connected to outer device from LAN in which private IP addresses are
used or allocating port numbers to each users, the private IP addresses can be used in transmitting message.
FIG. 13 illustrates group-independent message transfer system in accordance with
preferred embodiment of the present invention.
Referring to FIG. 13, the group-independent message transfer system 200 includes
a message transmitting processor 210 for acting as a server and a message receiving
processor 230 for a client in the message delivery group. The process of transmitting and
receiving of the message transmitting processor 210 and the message receiving processor
230 are controlled and managed by high level command processor 202. When a user
plays a role of group manager, the user must store and manage the IP addresses, names or
other information for the group subscribers in the message delivery group. Thus, the
database 250 is needed for user's information for the group subscribers.
The message transmitting processor 210 includes a connecting screen control
module 211 for displaying the connected group subscribers in the screen, a message
transmission module 212 for transmitting message to each group subscribers and a member
management module 213 for managing information of the group subscribers in the
message delivery group.
The connecting screen control module 211 displays information of the group
subscribers connected to the group manager in the screen of the group manager for acting
as a server of the group manager in the message delivery group. The message transmission module 212 transmits the message made by group manager to each group
subscribers using IP address. The member management module 213 stores and manages
the user information such as a IP address, a name or a connecting line of the group
subscriber belonging to the message delivery group in database 250 and checks the
connecting state of the group subscriber.
The message receiving processor 230 includes a message receiving screen control
module 231 for displaying the received message in screen, a user information management
module 232 for managing the user information and a message receiving module 233 for
receiving the transmitted message.
The message receiving module 233 ascertains and receives the message
transmitted from the group manager acting as a server in the message delivery group. If
the group subscriber does not use authenticated IP address but private or flouting IP
address, the message receiving module 233 ascertains message ready to transmit to the
message delivery group owing to connect to the group manager in regular time interval.
When the message ready to transmit exists, the message receiving module 233 take the
message from the group manager. The user information management module 232 stores
and manages the user information such as an IP address, an ID, a name or a password.
The message receiving screen control module 231 displays the message transmitted from
the group manager in the user's screen for ascertaining of the user. Because success of the
business depends upon transmitting speed of messages such as stock quotation, prompt reports, press news of newspaper or broadcasting reporters, or information of auction
tending and futures trading, it is preferred to pop up the transmitted message in the screen
of the user automatically.
FIG. 14 is an illustration of main screen in the group subscriber acting as a client
in the group-independent message transfer system in accordance with preferred
embodiment of the present invention.
Referring to FIG. 14, the main screen in the group subscriber can be distinguished
into display screen for displaying received message and functional icons the group
subscriber could select.
A chatting icon makes possible to communication between a group manager acting
as a server and a group subscriber acting as a client or among the group subscribers in the
message delivery group. When the group manager or group subscriber selects the
chatting icon, the chatting module is accessed and the display screen will be converted to
chatting screen. A registration icon is used for user's entrance to specified message
delivery group as group subscriber. The user must inputs information such as IP address,
name, ID, password or phone number for registering as group subscriber. A connection
icon is used for connecting the group subscriber to the group manager in selected message
delivery group among a plurality of groups registered by the group subscriber in
accordance with selection of the group subscriber. FIG. 15 is an illustration for transmitting message from group manager acting as a
server to group subscriber in message delivery group in the group-independent message
transfer system in accordance with preferred embodiment of the present invention.
Referring to FIG. 15, the group manager in the message delivery group can get the
connected list of group subscribers at present and transmit the same message to the group
subscribers belong to the message delivery group at the same time. Thus, the group
manager can transmit prompt message such as stock quotation, stock news and press news
to group members (group subscribers) that belong to the group manager as one lump
package. On the other hand, the group manager can establish the system for transmitting
e-mail or SMS message to mobile terminal of the group subscriber in the state of not
connected.
Furthermore, the group-independent message transfer system of the present
invention may include a translation function for delivering message among users using
different languages, 1:1 chatting function between users or speaking function using speech.
Also, it can use document processing function by accessing object beyond text message.
FIG. 16 illustrates a schematic diagram of application module capable of accessing
additively in the group-independent message transfer system in accordance with preferred
embodiment of the present invention. Referring to FIG. 16, application module 300 includes a speech processing module
302 for making possible to dialogue using speech among users, translation module 304 for
translating one language to another language, chatting module 306 for making possible to
chat among users and document processing module 308 for making document. In addition
to the modules of FIG. 16, a moving picture processing module for delivering moving data
among users can also be included.
The speech processing module 302 converts speech signal entered from speech
input device such as microphone to digital signal, e.g., binary code. The digital speech
signal is transmitted to the group subscriber in the message delivery group through the
same path with message transmission path from the group manager. The group subscriber
received the digital speech signal converts that using speech processing module 302. The
voice of the group manager is generated through the output device such as speaker in the
computer system of the group subscriber. That is, the group subscriber can listen the
speech signal transmitted through speech input device by speech output signal instead of
the message of the group manager.
The translation module 304 is used for transmitting message among users (group
managers and group subscribers) of different languages. When the translation module is
used, a language code is added to the message for transmission. Therefore, the group
subscriber interprets the language code added to message. If the transmitted message is
composed of other language, the message will be translated to language of the group subscriber by translation module and displayed to screen. Thus, users of different
language in the same message delivery group can transmit message conveniently not
considering any language.
The chatting module 306 displays the process of transmitting message from the
group manager to the group subscriber or from the group subscriber to the group manager
in message delivery group in one screen for ascertaining with each other. When the group
manager opens a chatting window, a user who wishes to chat in the group subscribers can
join the chatting. User (group manager and group subscriber) joined in chatting can
transmit/receiver message via a window. Thus, users can transmit message on the same
space like conversation with removing inconvenience of delivering the message through
each windows.
Particularly, storing the contents of menus on the message processing window, the
menus are displayed in the form of corresponding language in accordance with selecting
the language module by the user. Thus, it is convenient to the user.
The document processing module 308 can use functions such as HANGUL or MS
WORD in the message transfer system beyond simple message transmitting like text.
When the group manager intends to make message using table, line or a various style of
penmanship except the text message, a specified document processing module 308 is
accessed by Application Program Interface (API). The useable document processing
module 308 is limited to pre-specified application and interface for opening the document processing module will be produced and embodied through a contract with a person who
has a right for the application. For giving makikg facility of message through the
document processing module 308, an executing screen of the document processing module
308 is displayed in the display screen of the message transfer system. That is, the display
screen of the message transfer system is used as a session of the document processing
module 308 except opening new session by executing the document processing module
308.
The message made by the document processing module 308 is transmitted with
identification code for the document processing module 308. Thus, the group subscriber
received the message can ascertain the message easily by accessing the document
processing module 308 due to the identification code and displaying the message in the
screen.
The above application modules can be used more effectively by agreeing on a
using contract with a developer for each application modules that calls inner processing
function and links substantially with message transmitting module.
FIG. 17 illustrates a schematic diagram in case of having application modules in
the group-independent message transfer system in accordance with preferred embodiment
of the present invention.
This is described in the below referring to FIG. 17. The group manager or group subscriber can use, for example, windows 98 as OS
in the computer system. The OS provides high level command to API 192 and controls
the operation of each application modules.
The group-independent message transfer system 200 includes a high level
command processor 202; discriminates corresponding message transmitter 210, message
receiver 230 or each application modules in accordance with a high level command from
the API 192, decodes the high level command and transmits that to corresponding position.
The message transmitter 210, message receiver 230 and application module controller 250
controls the operation of message transmitting, message receiving and application modules
302, 304, 306 and 308 in accordance with command provided from the high level
command processor 202. The high level command processor 202 decides whether
specified application module is or not in accordance with high level command provided
from the API, decodes the high level command to a low level command capable of being
perceived in specified application module when the corresponding application module is
exist, transmits the command to specified mapper and controls transmittance of the
message.
The application module controller 250 includes a plurality of mappers 251, 253,
255 and 257, and interfaces 252, 254, 256 and 258 to a speech module 302 for transmitting
speech message, document processing module 308 for accomplish function of the word
processor, a chatting module 306 for providing function of chatting with each other, and a translation module 304.
The speech module mapper 251 receiving high level command transmitted from
the high level command processor 202 for the sake of transmitting/receiving speech
converts the command to a device level command to process in the speech module 302 and
provides the device level command to the speech module 302 via the speech module
interface 252. If a user intending to transmit message in a message delivery group inputs
his voice in a speech input device like a microphone, the voice is converted into digital
voice signal by the speech module 302 and the digital voice signal is transmitted to the
group subscriber belong to the message delivery group. The group subscriber provides
the digital voice signal, which received via the speech module mapper 251 and speech
module interface 252, to the speech module 302. The speech module 302 converts the
digital voice signal to voice and outputs that to a speech output device like speaker. Thus,
the group subscriber can listen the voice contents transmitted from the group manager.
The document processing module mapper 253 and document processing module
interface 254 are parts for making use the document processing module 308 in case of
intending not to make text message but document with word processor by user. The
document processing module mapper 253 converts high level command, which is for using
document processing module 308, received from the high level command processor 202 to
a device level command and provides the device level command to the document
processing module 308 via the document processing module interface 254. For the function of the document processing module 308, a session for document processing lends
the session of the message processing window temporarily not using new window. Since
the message transfer system 200 calls the document processing module 308, which is
closed in using the speech module 302, chatting module 306 or making text message, only
for a time to use the word processor according to a user's request, the speed and efficiency
for the data processing can be enhanced.
For example, document edit owing to the document processing module 308
include functions of file, edit, view, insert, format and tool. The function of file includes
file open, file close, save, save as, printer setting and print. The function of edit includes
copy, cut, find and change. The function of insert includes Hyper Text Mark-up
Language (HTML), image, clip art and document file. The function of format includes
text, file size and file format. The function of tool includes language and language
conversion.
When a user transmitting message using document processing module 308 makes
and transmits a message, a code for document processing module 308 used by the user is
added to the message. Thus, group subscriber can ascertain the document processing
module 308 used by the group manager in accordance with discriminating the added code
in the received message. Therefore, the group subscriber calls the corresponding
document processing module 308 and displays the message in the screen using the
accessed document processing module 308. The chatting module 306 is part for the group managers or group subscribers
belonging to a message delivery group to register as manager of chatting room and to
dialogue with other user. For opening the chatting room, the chatting module mapper 255
receives the high level command from the high level command processor 202 and converts
that into device level command to be ascertained by the chatting module 306. The device
level command is provided to the chatting module 306 via the chatting module interface
256. Thus, users joined in chatting room can dialogue with each other by execution of the
chatting module 306. In this case, it is preferred to have the chatting session lend the
message processing window by accomplishing function of the chatting module 306 in the
message transmission screen.
The translation module 304 accomplishes function of translation to native
language of the group subscriber for being ascertained the message by the group subscriber.
It is preferred to accomplish the translation module 304 in the process of not transmitting
but receiving the message.
When the group manager makes a message and transmits the message to the group
subscriber in the message delivery group, a code for used language by the group manager
is added to the message. Thus, the group subscriber can ascertain the language of the
message used by the group manager.
Therefore, if the transmitted message is not composed of the language for the
group subscriber, the high level command processor 202 provides a command for translating the message to the translation module mapper 257. The translation module
mapper 257 converts the high level command to device level command to be processed by
the translation module 304 and provides the device level command to the translation
module 304 via translation module interface 258. Thus, the group subscriber can
ascertain the message in the native language although the group manager transmits the
message with different language.
On the other hand, the group manager in message delivery group can transmit the
message translated in group subscriber's language by storing language information for
each group subscribers, when the group manager registers users who wish to enter into the
message delivery group as group subscribers. That is, the group subscribers do not
translate the message received from the group manager, but the group manager translates
the made message into each language of group subscribers and transmits the translated
message to each group subscribers. In this case, load of the group manager for
transmitting message will be increased.
Specific member functions of the API 192 for accomplishing the above skill are
described like below.
An open API is used for opening the message transmitting module or other
application module in accordance with user's request.
A close API is used for closing used modules.
A copy API is used for copying received message when the group manager acting as a server in a message delivery group to a plurality of group subscribers.
A retrieve API is used for retrieving application module to be accessed in the
group-independent message transfer system.
A status API is used for determining operating status of message transmitting
module or other application modules.
An initialize API has a function to initialize message transmitting module or other
application modules for accessing.
A list API is used for ascertaining list of the user information related to group
subscribers in the message delivery group.
A register API has a function for registering information of the group subscribers
who wish to enter into a message delivery group.
An unregeister API is used for excluding registration of the group subscriber
entered into a message delivery group.
A read API is used for interpreting message data received from a group manager
or group subscriber.
A write API is used for making message to be transmitted.
An attribute API is used for adding an attribute of application module to a message
or discriminating the attribute of application module added to the message.
In consequence, a private API is accomplished in accordance with used application
module or form of message and thus, group manager or group subscriber can make a message and use specified application module.
In above, although the speech module, document processing module, chatting
module and translation module have been used as application modules in terms of one
embodiment, those skilled in the art will recognize that a moving picture processing
module, image processing module and wireless transmitting module for communicating in
wireless, etc, can be used.
Particularly, when a real time moving picture chatting is used, real time moving
picture processing module can be used with function for transmitting text message.
Also, message delivering and chatting are accomplished between a group manager
acting as a server and a group subscriber acting as a client in the message delivery group
and between group subscribers in the same message delivery group. A group manager
providing an IP address of a group subscriber in a message delivery group to another group
subscriber in another message delivery group owing to request of another, each group
subscribers can delivery message and chat with other group subscriber except a group
manager.
An operation of the group-independent message transfer system of the present
invention is controlled by allocating port numbers to group manager as server, group
subscriber as client and to each application modules that are used by group manager and
group subscriber.
For example, number 5000 as a primary port number for message delivering and chatting is allocated to authentication for a role of server in accordance with the request of
group subscriber in a message delivery group. Port number 6000 is used for message
delivering and chatting as server of group manager and port number 6001 is used for
chatting among group subscribers. Also, port number 7000 can be used for a group
subscriber to connect to a group manager as server and port number 8000 can be used for a
group subscriber to receive message transmitted from a group manager.
Such as above, data format delivering between group manager and group
subscriber is described like below in accordance with a example allocating port numbers.
FIG. 18 illustrates a data format transmitted according to group subscriber's
request for connecting to group manager in a message delivery group in the group-
independent message transfer system in accordance with preferred embodiment of the
present invention.
Referring to FIG. 18, transmitted data in process of connection request may
include destination IP address, port number, ID, password, user's name, e-mail, mobile
phone and source IP address.
The source IP address is an IP address of a group subscriber requesting connection
to a group manager and the destination IP address may be 16 bits of IP address of a group
manager. When the group subscriber requests connection to the group manager, port
number 5000 will be used for authenticating a role of server by the group manager. The ID, password, user's name, e-mail and mobile phone is information of group subscriber
who transmits message in case of entering into message delivery group and requesting
connection to a group manager in a registered message delivery group. Also, the source
IP address as an IP address of group subscriber for requesting connection to a group
manager may be 16 bits.
FIG. 19 illustrates a data format of message transmitted from a group manager
acting as a server to group subscribers in the group-independent message transfer system in
accordance with preferred embodiment of the present invention.
Referring to FIG. 19, a group manager acting as a server can transmit messages, in
which each message has same contents, to a plurality of group subscribers in a message
delivery group. For above object, destination IP address, port number, message content,
error check bit and transmission confirming bit are included to the message.
The destination IP address is an IP address of group subscriber to be received
message and destination IP addresses are added sequentially to a message to be transmitted
to each group subscribers. If a plurality of group subscribers exist in a message delivery
group, a group manager copies content of message as many as number of group
subscribers and transmits the messages for each IP addresses of the group subscribers. Port
number 8000 allocated for the group manager to play a role of client may be used.
The message content added by writing of group manager may be composed of ASCII code for text message or binary code for word processor and file. The error check
bit is used for judging occurrence of error in process of transmitting message, which
include the error check bit, and the transmission confirming bit is a part for judging receipt
of a transmitted message by a group subscriber. When the group subscriber receives the
transmitted message normally, a response signal indicating normal receipt for the message
is transmitted to the group manager. On the other hand, if the message would include error
or would not be transmitted to the group subscriber for specified time, the message can be
retransmitted or simple message can be transmitted to a mobile terminal of the group
subscriber.
FIG. 20 illustrates a data format of message transmitted from a group subscriber
acting as a client to another group subscriber in the group-independent message transfer
system in accordance with preferred embodiment of the present invention.
Referring to FIG. 20, a first group subscriber must know an IP address of a second
group subscriber for transmitting message to the second group subscriber in the same
message delivery group. Thus, the first group subscriber will request the IP address of
the second group subscriber to a group manager. Such as FIG. 18, port number 5000 may
be used for the group manager to authenticate a role of server.
After the first group subscriber recognizes the IP address of second group
subscriber for transmitting message, he transmits a message composed of port number, message content, source IP address, error check bit and transmission confirming bit using
the IP address of second group subscriber as destination IP address. In here, port number
8000 may be allocated because the second group subscriber plays a role of client for
receiving message. The source IP address is the IP address of the first group subscriber.
The error check bit and transmission confirming bit are same as in FIG. 19. Thus, the
second group subscriber can ascertain whom the user (the first group subscriber) having
transmitted message is.
FIG. 21 illustrates a data format transmitted for the case of using application
module as well as message transmitting module in a message delivery group in the group-
independent message transfer system in accordance with preferred embodiment of the
present invention.
Message transmitting using application module by a group manager referring to
FIG. 21 is like below.
Data transmitted from a group manager to one or more group subscriber more
includes a header indicating use of application module in message data illustrated FIG. 19
or FIG. 20. The header may include a code of used application module by the group
manager, a function code used by the group manager selected from among the functions of
an application module and a language code for controlling the translation module when the
group manager uses different language than the group subscribers. The code corresponding to application module used by the group manager is given
to the chatting module, translation module, document processing module like a word
processor and speech module except for making text message. Although a chatting
module, translation module, document processing module and speech module are
illustrated as application module in above, it will be appreciated that moving picture
processing module and image processing module, etc, can be included. The function
code indicates the function in an application module that is used by a user. For example,
when a group manager uses a magnification in document processing function for the
document processing module, the function code corresponds to that. The language code
indicates a language used by group manager. A group subscriber discriminates the
language code for transmitted message, translates and displays the message to his native
language by actuating the translation module when languages between the group manager
and group subscriber are different. Thus, the group manager for transmitting message
makes a message in the same method with general message transmitting method except
any function of translation although a group subscriber using different language in the
message delivery group.
When a message is transmitted by the group-independent message transfer system
described above, the rapid delivery of security message can be accomplished effectively
through a group, such as composed of a plurality of investors who receive stock
information from an expert. In addition, the group-independent message transfer system may be used in a group with vertical grade such as a case that a doctor for treating writes
out a prescription according to a result of examination and provides the prescription to
another doctor or nurse in charge.
Industrial Applicability
As described above, based upon group-independent message transfer method and
system of the present invention, rapid and correct message delivery is accomplished and
security of the message is supported among users in a message delivery group by
connecting a group manager and group subscribers in peer-to-peer except any web server
and forming a group with a group manager as core.
Each user can arbitrarily perform a message delivery group in which the user plays
a role of server and can register in another message delivery group. Thus, each user can
be a server as well as a client and transmits message effectively in accordance with
characteristic of the formed group.
Moreover, using translation module for translating the transmitted message to
native language of the group subscriber, message delivery can be easily and efficiently
accomplished although users in the same message delivery group are in use of different
languages.
Moreover, the message transfer system can use various functions of application,
which is performed by including private application module necessary for transmitting message, with united function composed of such as speech, chatting and word processor in
addition to text message in accordance with selection of user.
Although the present invention has been described in detail in terms of various
embodiments, it is not intended that the present invention be limited to these embodiments.
Narious modification and change within the spirit of the invention will be apparent to those
skilled in the art.
