Abstract

A message is sent by a first mobile station (102) to a second mobile station (118). The user of the first mobile station designates the second mobile station as a target and composes a message by recording voice or entering text information on the first mobile station. The mobile station then sends the message, along with the destination identifier, to a fixed equipment network that includes the EBTS (104), the BSC (106), and the mobile data gateway (108). The MDG utilizes the dispatch call resource to send the message by retrieving the current location of the second mobile station from the dispatch visitor location register (112) without queuing or storing the message. The MDG then communicates messages between the first mobile station and the second mobile station similar to setting up a dispatch call.

Description

Be used to carry out the method for wireless mobile instant messaging

Technical field

The present invention relates generally to mobile radio system, more particularly, the present invention relates to utilize data networking equipment between the mobile communication equipment and the method that between mobile device and client, sends message.

Background technology

Wireless mobile communications has far-reaching influence to the mode that many people carry on business, and brings great convenience for the general public.But, may be unsuitable in some cases or not wish to use mobile communication equipment, for example during important business meetings, perhaps other any be considered to disturb in.But it may be hoped to be used to send or receive the non-voice short message that does not need real-time response or do not need to respond.This class message transmission generally is to carry out between fixing evaluation work station, for example, and by Email or send to mobile device such as pager.Certain methods even response is provided quasi real time, for example so-called online chatting, wherein a plurality of users can add a discussion simultaneously, and have lower delay.Instant messaging is known gradually, and it is a mutation of online chatting, and in instant messaging, discussion is to carry out between two people on the remote work station.

Instant messaging and online chatting generally all will relate to the software program that activates on the computing machine that is connected on the network.This software program is an instant messaging " client ", it with multi-purpose computer that network is connected on move.After being activated, the instant messaging client requires to obtain usersaccount information, and is connected with the information receiving server.The information receiving client sends account to the information receiving server with the current network address of the computing machine that is used for current instant messaging.If the instant messaging client-side program arranged on the computing machine and be connected on the network, this measure allow the user on the different time with the identical different machine of instant messaging account number use.Instant message is the alphanumeric text strings of being write by first user, and text string is normally write in the text input window mouth at program user interface, and sends to second user or user's group by the instant messaging server.Server sends to final reception client with this message, and client then demonstrates the message that receives at once once receiving.

The fact that tradition instant messaging service depends on the server of message queueing shows, always exists server process to postpone, and in the peak period of information receiving business, this delay is fairly obvious.The information receiving of other type also is subjected to the influence of intrinsic transmission delay during the network activity of peak as paging and Email (email).Radio communication such as paging and email provides good locomotivity, but also can bring minimum interference, and it is different with the mobile calls reception of calling party conversation when receiving incoming call with the user.Therefore, need a kind of wireless instant messaging system that is used for mobile client, even during peak traffic, it can not postpone message yet.

Preferred embodiment describes in detail

Although instructions is finally summed up with the claim that has defined the feature of the present invention that is considered to novel, can believe that by the following description also with reference to the accompanying drawings, the present invention will be better understood.In the accompanying drawings, identical label is being represented identical unit.Brief description to prior art also is very useful.

As mentioned above, the information receiving that is used for wireless system and many wired network systems in the prior art is ranked by server.Mean that by the server queuing message of sending from sender's equipment was kept on the server temporarily before sending.The example of this system comprises: email, paging and the Internet chat communication.The also reproducible message of chat server is to send them to a plurality of users that add identical discussion.Because be based on server, so network communication delay is decided by private resource amount and message volume.Obviously,, need more system resource, can occur postponing during the message on some point is transmitted along with the increase of message volume.In addition, many messaging systems (as paging system) all are blind, that is, the sender can't know the target receiver, and whether actual reception is to message.

The present invention by avoid using server and provide show the target receiver whether actual reception to the feedback that sends message, thereby solved the problems referred to above.This is by using direct client to finish to the communication of client on network.In a preferred embodiment of the invention, message is not lined up on any server and is sent by system.Benefit with scheduling channel rather than traditional duplex channel is, and only use duplex connects only about half of system resource, only needs half-duplex to connect because go up at any one time.

With reference now to Fig. 1,, wherein shown the wireless system 100 that is used to carry out wireless instant messaging according to of the present invention.Shown mobile communication equipment or transfer table 102 among the figure, it links to each other with fixed equipment network by air interface 103, and this network contains enhanced base station transceiver (EBTS) 104.Transfer table contains display device and input media such as alphanumeric keyboard of the information that is useful on demonstration such as text and various icons.It is a mobile radio communication apparatus, that is, and and the moved between positions that transfer table can be in service area, and can keep and being connected of fixed equipment network by exchanging to different base station sites, this is being known in the art.

In addition, any communication facilities of selling with trade (brand) name iDEN made from Motorola Inc. is the same, and this transfer table can be dispatched and call.These equipment all have " button-conversation " function, and this function allows transfer table and one or more other transfer table to carry out dispatch call.EBTS is connected with base station controller (BSC) 106, and the latter is controlling one or more EBTS unit on the given website to set up a Serving cell.BSC links to each other with mobile data gateway (MDG) 108 in other network equipment subsequently.BSC also can link to each other with (for example) mobile switching centre (not shown), and is such as known in the art, and this switching centre is used for setting up the duplex telephony conversation on public switch telephone network.Dispatch call refers to the half-duplex type communication that any correspondent is alternately mediated a settlement and listened.As known in the art, this can occur between two move operation persons, perhaps in so-called trunking mode (fleet mode) from an operator to a plurality of operators.Should not have more general, narrower implication and obscure mutually employed in the vocabulary that uses and (for example) public safety wireless system herein.

MDG108 links to each other with dispatch application processor (DAP) 110, and the latter is a communication agent processor that is used for convenient scheduling conversation.These callings all are semiduplex, in these are called out, once have only a platform to speak, and receiving platform then can only be listened.Dispatch call can carry out between two or more.When a user of mobile station was wanted to begin dispatch call, this user wanted the system identifier of the platform called out or user to think that the identifier of the particular talk group of speaking therein is selected on user's platform.When " button-conversation " button is connected, this will send information to DAP, and the latter then can pass through to check schedule access location register (D-VLR) 112, thereby orient the Serving cell of Target Station fast.The work of D-VLR is identical with the work of employed Visited Location Registor in the mobile telephone system basically, and it is used in time preserving the record of Serving cell at the current place of transfer table of each connection.The sub-district of other that this measure helps dispatch call is routed to apace that the caller platform calling out.Along with transfer table changes the position, its sub-district subordinate relation (cell affiliation) also obtains upgrading in D-VLR.MDG also can (for example: the internet 122 that wherein also has other server 124 and Internet chat client 126) the ip router l20 that links together be connected to external network with data network with wireless system 100 by (for example).

With reference now to Fig. 2,, wherein shown the process flow diagram that is used between mobile communication equipment, carrying out the method for wireless instant messaging according to of the present invention.Below with reference to Fig. 1 this method is described.202, the first transfer tables (as transfer table 102) are switched on and are connected with wireless communication system by air interface 103 when beginning.This just means that transfer table 102 is registered service, and its current subdistrict position is recorded among the D-VLR112.When the user of first transfer table determined to send an instant message, this user utilized the transfer table compose-message.Transfer table contains keyboard and display, and is such as known in the art, and they are convenient to the input of alphanumeric information, and the user utilizes them to write out alphanumeric message (202).But, can estimate, also can be recorded as short message, and the speech message of noting is carried out numerical coding for transmission by language the user, thus compose-message.The user also must select a target (206); That is, want employed second transfer table of the people who transfers immediate news by this user.Select in the database of object identifier that the user can be from be kept at storer, code name preferably by selecting one to be associated with object identifier, perhaps the user also can directly import object identifier.This object identifier is used for discerning the user by communication system to be wanted which transfer table to send message to, and it can be (for example) Internet protocol (IP) address.Then, the user sends (208) message with transfer table.This can finish by " button-conversation " button that (for example) presses on the transfer table.Object identifier and message subsequently are sent to a fixed equipment network.This fixed equipment network comprises all the non-moving unit in the communication system, comprising: EBTS104, BSC106, MDG108, DAP110 or the like.In a preferred embodiment, air interface 103 is time-division interfaces, and promptly such as known in the art, transfer table transmits and receive data on certain time slot.

Fixed equipment is the receiving target identifier at first.Information is received for example grouping shown in Fig. 3 300 with the form of grouping.Such as known in the art, in each grouping, contain the header 302 of data type of the useful load 304 of an expression grouping.Begin to show to fixed equipment network that by the given content the input packet header transfer table is attempting to send instant messages from the information that transfer table receives.The grouping that fixed equipment network will receive sends MDG108 to.MDG receives information, find that transfer table attempting to transfer immediate news, the searching target identifier is to determine target (second transfer table is as transfer table 118) whether current available (210) in D-VLR, if available, determine then it currently just with which unit is connected.Then, MDG sends information to the 2nd EBTS116 (214), and the latter then handles the Serving cell as second transfer table, 118 places of target.EBTS116 calls out second transfer table has output data and the data will be in which channel (216) to remind it.Second transfer table is tuned to suitable channel and begins to receive instant message.When receiving instant message, or after the very short time of the information of receiving, second transfer table will return a confirmation (220) to first transfer table, and demonstrate the information (222) that receives on the alphanumeric display can showing.Second transfer table preferably can send an audio or video alarm to the user when receiving message.Message can show when receiving warning, perhaps also can show automatically in the requirement according to the user.Like this, (224) have just been finished in instant messaging.

There is several method can handle the current invalid situation of second transfer table when first transfer table begins to send message.Have a kind ofly to be, first transfer table can be before sending message or even second transfer table of before first user writes outbound message, " surveying (ping) ", as shown in Figure 4.For example, first user wonders whether second transfer table is using and can receive instant message.First user only selects the identifier (400) of second transfer table in the proper handling pattern of first transfer table, and takes some actions, for example: press " button-conversation " button.This identifier is sent to MDG (402) by fixed equipment network.Then, MDG searches for this identifier (404) in D-VLR.If MDG does not find the record of second transfer table in D-VLR, then it can return a failed message (406) to first transfer table.This with previous when MDG does not find the identifier of second transfer table in D-VLR when whole message attempts to send to second transfer table what happens identical.If object identifier is found, then MDG will return a confirmation (408), and then, the user just can proceed writing of message.In an alternative, the user can write outbound message, and if second transfer table is invalid, then first transfer table can automatically attempt to send this message in previously selected interval repeatedly.When second transfer table 118 is put among the D-VLR, no matter but be subjected to the calling of EBTS116 or when after message sends, all not responding, can use a kind of alternative methods.Best, when first transfer table sent message, it started a timer.If after previously selected a period of time, do not receive the confirmation information yet, then first transfer table shows a failure information to the user.Owing to utilize this method on the fixed equipment network message being had very low delay when a transfer table sends to another transfer table, thereby can expect, receive a correct affirmation information and will only need be no more than the time in several seconds.So, for example, if through not receiving acknowledge message after 5 seconds as yet, the then transmission of first transfer table failure.

Can also expect, the user of transfer table might need to utilize fixed terminal or other terminal on public network (as the internet) to send message.As shown in Figure 1, MDG is connected with ip router 120, and the latter is used for wireless communication system and internet 122 are coupled together.What connect the internet also has, for example, and chat server 124, and the operation chat clients is to the computing machine 126 of application program.This chat client application program allows the user of client-side program to use unique title or identifier to sign in on the chat server by the internet, preferably carries out at once after program is opened.Other user can utilize similar program to sign in on the chat server, and exchanges messages mutually between server.Server receives message from a client, and information is ranked, and then message is dispatched successively the target to all appointments.Chat server is to carrying out the queuing of first-in first-out from the message of client.

Under first kind of situation, transfer table 102 is used to send message to Internet chat client 126.Fig. 5 has shown the process flow diagram that is used to finish a kind of method of this process according to of the present invention.At first, as previously mentioned, the user writes out message (500) (it can be a speech message of noting or an alphanumeric message) and chat client identifier (as the IP address, other identifier that perhaps unique title or chat server use).Certainly, the network address of chat server is also contained in wherein, although it can be provided by the information receiving application program on the transfer table.Transfer table sends to fixed equipment network with message, and it is cordless communication network target in addition that the latter then identifies given content, and this message is sent (502) to ip router 120.Ip router is given chat server 124 by the internet with message scheduling, and the latter then receives this message (504).After receiving message, the chat client of chat server search appointment is to determine whether this chat client has signed in to (506) on the chat server.If not, then will return a failure information, and send it back transfer table (508).If chat client is online, then message will be scheduled to chat client.

The process flow diagram of Fig. 6 has shown according to of the present invention when the method for chat client when transfer table sends message in the other direction.At first, chat client 126 signs in on the chat server 124 by the internet.Then, the user of chat client writes out and sends a message (602), and suitably specifies it.This measure comprises specifies specific wireless communication system, though it can be realized by the I address that utilizes specific ip router/MDG simply.It is one of transfer table that chat server identifies given content, and sends message to ip router, and the latter then gives MDG (604) with message scheduling.MDG searches the transfer table (606) of appointment in D-VLR then.Be not listed if transfer table is current, then a failure information will be returned to chat client (608).Otherwise message will be scheduled to the Serving cell (610) at the current place of transfer table of appointment, and as mentioned above, message is moved platform (612) and receives.What should expect is that transfer table can produce a confirmation when receiving message, and by network it is sent it back the Internet chat client.Also can expect, if do not receive response when any one transfer table from client sends message, the equipment of then attempting the information that sends will demonstrate failure information in predetermined a period of time.

Like this, the present invention sends message like that by being similar to the scheduling conversation that does not need to line up between transfer table, thereby has solved delay issue and increased the cost rising problem that server causes to avoid postponing.This measure can utilize existing resource accomplished in a kind of new mode.Specifically, it can utilize the transfer table compose-message, and is pressing the button the whole message of back transmission, and need not to preserve in system message.Message can be record voice or digital alphabet text.In addition, the present invention allows transfer table by internet and Internet chat client exchange message.Though above preferred embodiments of the present invention have been disclosed for illustrative, obviously the present invention is not limited to this.For a person skilled in the art, do not breaking away under the situation of the spirit and scope of the present invention that limit by claims, various modifications, conversion, variation, replacement and equivalent way can arranged.
