Hereinafter, examples of the modalities of the system and method for interconnecting messages of mobile communication terminals in accordance with the present invention, will be explained with reference to the attached drawings. Here, it is important to note that all of the entities specified in Figures 1 to 4 may not be necessary, such as the WAP Gateway (described below), for the achievement of the present invention, since many other types of network entities may also perform the desired operations and different operations and processing could also be combined and performed within a single entity. The person skilled in the art can clearly understand that the particular network entities described hereinafter constitute only examples that are used to explain the features of the present invention, which could also be achieved by other different types of hardware, software, and / or any combination of equivalent hardware and software. Figure 1 describes an example structure of an interconnection system for message communication services of mobile communication terminals in accordance with the present invention, by means of which the system is used to interconnect a message communication service terminal instant with a multimedia message communication service terminal. As shown in Figure 1, the system comprises a transmitting terminal (10) that stores and transmits multimedia content formed by a user; an instant message server (20) that checks whether the multimedia content transmitted from a transmitting terminal (10) can be transmitted to a receiving terminal (50); a multimedia message service center (MMS) (30) that revises a format and codec of the multimedia content transmitted from the instant message server (20) and converts it into a content format supported by the receiving terminal (fifty); a WAP Gateway (40) that notifies the receiving terminal (50) when the multimedia content is input to the multimedia message service center (30); a receiving terminal (50) requesting the multimedia content notified from the multimedia message service center (30) through the WAP Gateway (40), as well as receiving the requested multimedia content through the WAP Gateway (40); and a mobile central network (60) that performs authentication and authentication, as well as performs periodic or non-periodic updating of the information of a transmitting terminal (10) and the receiving terminal (50). Here, the instant message server (20) is a first server for processing instant messages and the multimedia message service center (30) is a second server for processing multimedia message services. A transmitting terminal (10) is a mobile communication terminal having an instant message client installed in that site, while the receiving terminal (50) is a mobile communication terminal having a multimedia message service client (and not an instant messaging client) installed on that site. The instant message server (20) allows the transmission of multimedia content at the request of a transmitting terminal (10) and reviews the information stored in a mobile central network (60) to determine whether the receiving terminal (50) to which it is to be transmitted the multimedia content has an instant messaging client or multimedia messaging service client installed on that site. Figure 2 describes a block diagram of an example structure of an instant message server according to the present invention, comprising a transceiver module (21) that receives multimedia content and a similar one transmitted from a transmitting terminal (10) and transmit it to a different server; a receiver terminal review module (23) that performs address resolution for the destination of the multimedia content that is to be transmitted and reviewed from a central mobile network (60) if the receiving terminal (50) has a multimedia message server client installed on that site; and a storage module (25) temporarily storing the multimedia content transmitted from a transmitting terminal (10). The multimedia message service center (30) determines whether the format / codec of the multimedia content received from the instant message server (20) is supported by the receiving terminal (50). If the format / codec of the multimedia content is supported, the multimedia content is not converted, but transmitted directly to the receiving terminal (50), but if the format / codec of the multimedia content is not supported, the multimedia content is converted to a format / codec which is appropriate for the receiving terminal (50) and is then transmitted. Figure 3 describes a block diagram of an example structure of a multimedia message service center in accordance with the present invention comprising a transceiver module (31) that receives multimedia content from the instant message server (20) and transmits it the multimedia content that has been appropriately converted for the receiving terminal (50) to a different server or to the receiving terminal (50); a notification module (33) that notifies the reception of the multimedia content to the receiving terminal (50); a storage module (35) temporarily storing the received multimedia content; and a conversion module (37) that revises the format / codec of the received multimedia content and converts the multimedia content in accordance with the capabilities of the receiving terminal (50). A mobile central network (60) is a generic user profile (GUP) server of 3GPP TS 23.240, which employs a simple mail transfer protocol (SMTP) to exchange information with the instant message server (20) and the multimedia message service center (30). Here, a mobile central network is defined in the interpersonal message communication system (IMPS) of the wireless village of the Open Mobile Alliance (OMA) standard. Figure 4 describes a block diagram of an example of structure of a mobile exchange according to the present invention, comprising a transceiver module (61) that receives information request signals from the instant message server (20) or the multimedia message service center (30) or a terminal, or transmits certain information; an authentication module (63) that performs authentication and authorization for each element of inclusion of the system or for each subscriber; a database (65) that stores and periodically or non-periodically updates subscription information of the user terminal service, user profile information, presence information, access rights information and the like; and a starting location record (HLR) (67) that manages the network information of the terminal. The operations of the system for the interconnection of message communication services of mobile communication terminals with the structure identified above will be described hereinafter. When a sender enters and transmits multimedia content through an instant messaging client of a transmitting terminal (10), the multimedia content is entered into the instant messaging server (20). The instant message server (20) reviews the address of the destination to which the multimedia content is to be transmitted, and when making the address resolution, it checks whether the receiving terminal 950) has a multimedia message service client (and not a client of instant messages) installed on that site, to subsequently transmit the multimedia content to the multimedia message service center (30). The multimedia message service center (30) reviews the format / codec of the transmitted multimedia content, to determine if the receiving terminal (50) supports that format / codec. If the format / codec of the multimedia content is of the type that is supported by the receiving terminal (50), the multimedia content is not converted, but transmitted directly to the receiving terminal (50), whereas if it is not of the type supported by the receiving terminal (50), the multimedia content is converted to a type that is supported by the receiving terminal (50), to be subsequently transmitted. The multimedia content is transmitted to the receiving terminal (50) through the WAP Gateway (40) and the receiver can review the content of the transmitted multimedia content using the multimedia message service client installed in the receiving terminal (50). In particular, in accordance with the message interconnection system of mobile communication terminals of the present invention, even if the multimedia message service client is installed in the receiving terminal (50) instead of an instant message client, the receiving terminal (50) can receive the multimedia content transmitted by a transmitting terminal (10) using an instant message client. Here, a transmitting terminal (10) and the instant messaging server (20) receive from a mobile central network (60), information that the receiving terminal (50) does not have an instant messaging client installed on that site, but only has a multimedia messaging service client installed on that site. Figures 5 and 6 describe flow diagrams of an example method of interconnecting messages of mobile communication terminals in accordance with the present invention. Initially, the sender activates the instant message clients installed in a transmitting terminal (10) and reviews the message client installed in the receiving terminal (50) (S11). Here, a transmitting terminal (10) has installed on that site the same instant messaging client as that at the receiving terminal (50), or has a single multimedia messaging service client (which is not an instant messaging client). installed on that site, or you have both an instant messaging client and a multimedia message client installed simultaneously on that site. In the present invention, it is assumed that a transmitting terminal (10) has an instant message client installed in that site and the receiving terminal (50) has a multimedia messaging service client installed in that site. After the sender creates the multimedia content using the instant message client, the multimedia content is transmitted to the receiving terminal (50) (S12). Here, if other content in addition to the multimedia content is to be transmitted, a transmitting terminal (10) may inform the sender that said content can not be sent. This is because the multimedia message service client installed in the receiving terminal (50) can only receive multimedia content and, therefore, if the sender tries to transmit other types of content, a transmitting terminal (10) can generate a alarm to inform the sender. The instant message server (20) that has received the multimedia content, reviews the address of the receiving terminal (50) (S13), receives the information from the receiving terminal (50) provided from a mobile central network (60), for then check if only a multimedia message service client is installed in the receiving terminal (50) (S14). When determining whether an instant messaging client is installed in the receiving terminal (50) (S15), if an instant messaging client is not installed, but only a multimedia messaging service client is installed, the messaging server is installed. instant (20) transmits the multimedia content to the multimedia message service center (30) (S 6). If an instant message client is installed in the receiving terminal (50), the multimedia content is transmitted to the receiving terminal (50) via the Gateway (40) (S17) and, if both an instant messaging client as a multimedia message service client are installed in the receiving terminal (50), the multimedia content is transmitted in accordance with the network or user selection specifications (S18). Here, it is determined whether the multimedia content should be transmitted to the instant message client or the multimedia message service client in accordance with the specifications of a network or user selection. The multimedia message service center (30) temporarily stores the multimedia content and informs the receiving terminal (50) through the Gateway (40) transmitting a brief message to indicate that the multimedia content has been received (S19). When the receiver operates its receiving terminal (50) to request the reception of the multimedia content through the Gateway (40), the request signal is transmitted to the multimedia message service center (30) through the Gateway ( 40) (S20). The multimedia message service center (30) receiving the request signal checks whether the format / codec of the multimedia content is supported by the receiving terminal (50) (S21). If the format / codec of the multimedia content is not supported by the receiving terminal (50), the content is converted to a content format that is supported by the receiving terminal (50) (S22) and if the format / codec is supported, then the format of the multimedia content is not converted. The multimedia message service center (30) transmits the multimedia content that has or has not been converted to the receiving terminal (50) through the WAP Gateway (40) (S23). The receiving terminal (50) receiving the multimedia content transmits to a transmitting terminal (IO) a delivery report signal indicating that the content has been received (S24). Figures 7 to 9 describe an example of modality for reviewing whether a multimedia message service client of a receiving terminal (50) exists using an instant message client of a transmitting terminal (10) in accordance with the present invention. Special characters can be used as subscripts or superscripts, or colors can be used to distinguish users (receiving terminals). Here, each icon displayed in the instant message clients refers to a receiver or receiving terminal (50). Figure 7 describes an example where the online and offline states of the receiving terminals (50) that have an instant message client installed in that site and those receiving terminals (50) that do not have an instant communication client of messages installed on that site, can be indicated in different colors. In addition, between the receiving terminals (50) that do not have an instant messaging client installed in that site, those that have a multimedia messaging service client installed in that site can be indicated with a letter '? T to indicate that the service of Multimedia messages would be possible with that terminal. Figure 8 describes an example in which the online or offline states of the receiving terminals (50) having an instant message client installed in that site are indicated in different colors, while the receiving terminals (50) they do not have an instant messaging client installed on that site, they are indicated in the same color as those receiving terminals (50) that have an instant messaging client on that site, but which are in the offline state. In addition, between the receiving terminals (50) that do not have an instant messaging client installed in that site, those that can support a multimedia messaging service, can be indicated with a letter 'm' to indicate that the multimedia messaging service It would be possible with that terminal. Figure 9 describes an example in which the instant message client uses special characters (as subscripts) to distinguish different types of services supported by the receiving terminal (50), such as multimedia message services, instant messaging services, of location and others similar. The online and offline states for the instant service are distinguished by different colors, while the receiving terminals (50) that can support the multimedia message service may have a subscript '? T added to them to indicate that the multimedia message service is possible. Here, the subscript '? T can be added to all the receiving terminals that can support multimedia messaging services, regardless of the online or offline states of their their instant messaging clients. As a method to check whether or not a multimedia message client is installed in a receiving terminal, in addition to the method of checking the colors or subscripts of the icons described above, you can also use a method of reviewing the registration information of the corresponding icons in the receiving terminal. In particular, since the icons also contain registration information that includes information about the message client installed in the corresponding receiving terminal, the user can select a certain icon to review his registration information, in order to check whether the receiving terminal has a multimedia message client installed on that site. Figure 10 describes a signal flow of a system for interconnecting mobile communication terminal messages in accordance with the present invention. As shown in Figure 10, when a transmitting terminal (10) uses its instant message client to transmit a multimedia content transmission signal (SendMessage.Req) to the instant message server (20), the instant messaging server ( 20) transmits to a transmitting terminal (10) a response signal (Send Message. Res) with respect to the multimedia content signal (A 10). The instant message server (20) that has received the multimedia content from the transmitting terminal (10) transmits a multimedia content transmission signal (ForwardMessage.Req) to the multimedia message service center (30) and receives a response signal (ForwardMessage. Res) with respect to the transmission signal from the multimedia message service center (30) (A20). The multimedia service center (30) that has received the multimedia content from the instant message server (20) transmits a notification signal (MessageNotification.Req) to the receiving terminal (50) to indicate that the multimedia content has been received and receives a response message (MessageNotification.Res) with respect to the notification signal (A30). The receiving terminal (50) that has received the notification signal transmits a multimedia content request signal (Get essage.Req) to the multimedia message service center (30) and receives a response signal (GetMessage.Res) including the multimedia content (A40). The receiving terminal (50) that receives the multimedia content stored in the multimedia message service center (30), transmits a complete transmission signal (MessageDelivered, in English) to the multimedia message service center (30) (A50), which then transmits a transmission report signal (DeliveryReport.Req) to the instant message server (20). The instant message server (20) that has received the transmission report signal transmits a response signal (DeliveryReport. Res) to the multimedia message service center (30) (A60), and transmits to a transmitting terminal (10). ) a transmission report signal (DeliveryReport.Req) indicating the termination of the transmission of multimedia content (A70). Figure 11 describes a structure of a basic architecture of an interconnection of message communication services in accordance with the present invention. A block diagram of the logical entities is shown, which can include the interconnection of different message communication services and the details of each of the entities will be described. The message communication relay (nter-service) (MR) is a logical entity responsible for the transfer of a message between two message communication services. These responsibilities include identifying the objective message communication service based on the resolution of the address and profile of the receiving user, the conversion of the message format to the accepted format of the message communication service receiver, as well as producing the appropriate billing records. for the transfer to the objective message communication service. In more detail, the MR interfaces with the different message communication servers (and can be implemented as part of a message communication server) to transfer the message information (both the content and the "envelope") between different services . In addition, it interfaces with the basic enablers for address resolution, access to the user profile and the persistent reception and storage of the message. MR is responsible for different functionalities, including the support of several protocols such as (but not exclusively) MM4, MM7, SMTP, different protocols based on SIP, etc.; and accepting that the messages are transferred to a different message communication server, where the message can either be explicitly provided or accessed through the link to a network storage. Other responsibilities include identifying the objective message communication service, which can be explicitly provided by the originating message communication service or determined from the user profile of the recipient; perform the conversion and adaptation of the message so that it has the formats of the objective message communication service; keep the message persistent storage until the message has been delivered successfully to the target message communication service; manage the sending of read and delivery reports that could be routed back from the recipient's message communication service to the originator of the message upon request and when there is support both of both origin and recipient message communication services; and maintain the privacy and security of message communication services. The address resolution (AdR, for its acronym in English) is a logical entity responsible for the termination of the abbreviated address to be a fully qualified address in accordance with the address format used by the destination service of message communication. In more detail, the AdR is an interface between a message communication server or the message communication relay (MR) and the address book that allows the expansion of the address of a given receiver. the fully qualified address that identifies the destination server and receiver message communication service for the delivery of the message. The interface should support the introduction of any address format, including abbreviated "nicknames" and an indication of the desired format of the fully qualified format, as well as return the fully qualified address or an indication that none of these addresses is available for the introduction provided. The user profile is a logical entity that defines certain information that must be defined within the profile of users that subscribe to message communication services and must be accessible to the message communication servers and the message communication relay ( MR, for its acronym in English). In more detail, the user profile provides both an interface between the message communication server (or MR) and the user information database within the operator's domain, as well as a specified set of User parameters that indicate a minimum set of attributes. Attributes should at least include certain types of information, such as a list of message communication services to which the user subscribes, a list of "preferred" message communication services that the user would define to receive different types of media. and parameters of communication of basic messages The transcoding of header and content is a logical entity that provides transcoding services, either in header formats or message content between the formats of different message communication services. Transcoding services provide services to the message communication server or the MR to perform the adaptation of the message and content format.This can be supported by an extended version of the Standard Transcoding Interface (STI). must allow the transformation of the header information and not only between the content information that is currently supported. The message store (storage) is a logical entity that provides persistent storage of messages on the network that could be accessed through the message communication servers and the message communication relay (MR, for its acronym in English) to store and retrieve the message that is being sent. In greater detail, message storage provides persistent storage for messages that must be accessible throughout the message communication services provided by the operator. In particular, the storage of messages must provide an interface that allows the storage of messages in different formats (eg, email, multimedia messages (MM), short message service (SMS, for its acronym in English ), etc.), generation of URI for messages, recovery and replacement of the message in the storage based on URI, as well as storage management through the message communication servers or the MR.

Among said different network entities, there are reference points (e.g., interfaces) that are necessary. The following table 1 lists each reference point and its relevant description.

Figure 12 describes a structure of a basic architecture of an interconnection of message communication services in accordance with the present invention. As in figure 11, a block diagram of the logical entities is shown, which may include the interconnection of different message communication services and the interfaces (reference points) between them, although the details of the different characteristics will explain. The sending side and the receiving side of FIG. 12, as well as the originating side and the receiving side of FIG. 1, respectively, have equivalent logical entities. For example, the sending message communication services interconnect server and the receiving message communication server in FIG. 12, respectively, correspond to the recipient origin service message server and the message communication server of the recipient. Preferred receiver services in Figure 1. However, in Figure 12, it is shown that the source message communication server and the interconnection server for sending message communication services can be part of the same logical entity. In particular, a single server can perform the functions of both servers, as indicated by the dotted lines in Figure 12. In addition, the address resolution and message store in Figure 11 correspond, respectively, to the address and storage converter of the server. messages in figure 12. Additionally, the presence server in figure 11 cooperates with the origin message communication server and the receiver origin service message communication server, while the presence server in figure 12 cooperates with the origin message communication server and the receiver origin service message communication server. cooperates with the originating client and the origin message communication server. Additionally, on the receiver side of FIG. 11, the message store is connected to the interservice message communication relay and the receiver preferred service message communication server, while on the receiver side of FIG. 12., the storage of messages is connected to the interconnection server for sending message communication services, the message communication relay and the reception message communication server. Figure 13 describes a flowchart of a method for interconnecting message communication services in accordance with the present invention. With reference to figures 11, 12 and 13, the present invention also provides a method for interconnecting between different message communication systems, the method comprising: sending through a terminal to a source message communication server, a message including the type of message communication service preferred by the receiver; receiving the message by means of a server of communication of messages of services of origin of receiver; and sending a transcoded message to a recipient's preferred service messaging communication server, considering the received message that includes the preferred recipient's message communication service type, without reviewing any other network entity to obtain information about the type of message. receiver's preferred message communication service. In other words, the transcoded message is sent to a message service server of preferred receiver services, without having to review other network entities as a user profile to find the type of recipient's preferred message communication service, given that only the received message that includes the type of recipient's preferred message communication service should be considered. Here, the step of sending the message that includes the type of recipient's preferred message communication service further comprises the steps of performing the address resolution, reviewing a user profile and storing the message before sending it. In addition, the step of sending the transcoded message further comprises a step of converting the received message having a first format to a second format, to allow compatibility between different types of message communication services. Additionally, the origin message communication server receives from a presence server, status information and possible service applications related to a receiver terminal before sending the message that includes the type of recipient's preferred message communication service.

Additionally, the present invention provides a method for connecting different message communication systems, the method comprising: receiving a message related to a message communication service; obtain the type of message communication service preferred by a receiver; inserting in the received message, at least one parameter related to the type of preferred message communication service obtained; and sending the received message having the parameter inserted in that site to a message server of receiver origin service messages. This method may additionally comprise a step of finding a destination message communication system to which the received message is to be routed, wherein the preferred message communication service type is obtained from a presence server or a user profile, in wherein the at least one parameter is for sending or receiving a message from the preferred message communication service, as well as wherein the at least one parameter includes a parameter for sending a message of the preferred message communication service and another parameter for receive a message from the preferred message communication service. In addition, the present invention provides a method for connecting different message communication systems, the method comprising: receiving a message having a parameter at that site indicating a preferred type of message communication service; processing the conformance message with the parameter to a format supported by the preferred message communication service; and providing the message to a recipient of the preferred message communication service. Here, the message may be received by a receiver communication service message server in a format that is different from the format of the preferred message communication service; and the processing step may include the step of performing the address resolution; and messages can be processed through a message communication relay to review a user profile, perform header and content transcoding and store messages; and the messages can be supplied to the receiver through a message service server of preferred receiver services. Additionally, the present invention provides a method of message communication service, which comprises: sending a message from a source client to a source message communication server; store the message in a message storage; obtaining user information through a presence server or a user profile, wherein the information contains at least one type of preferred message communication service; find a next server through the address resolution; send the message to the next server; transcoding a source message format to a receiver message format; find a message communication server for preferred receiver services through address resolution; sending the transcoded message to the receiver's preferred message communication services server; store the transcoded message and send a notification to the receiving client; requesting to receive the transcoded message to the recipient's preferred message communication service server; and receive the transcoded message. Additionally, the present invention provides a method of message communication service comprising: receiving, by means of a first message communication services server, a multimedia message sent by a first user user of a first message communication service; processing the multimedia message in the first message communication services server and in a second message communication services server; and provide through the second message communication services server, the multimedia message processed for a second user user of a second message communication service. Here, the processing modify the content or format of the multimedia message to allow compatibility between the first and second message communication services, as well as where the first message communication service is an instant messaging service and the second Message communication service is a multimedia message service. In addition, the processing check whether a message communication address is available to the second user user, as well as where the first message communication service is a multimedia message service and the second message communication service is a service of instant messages. Additionally, the first user client have functionality to indicate possible service applications and presence information for the user, as well as where possible service applications and presence information be indicated as a visual display provided for a user who employs different colors and text characters. Figures 14 to 24 describe more specific embodiments of the present invention which correspond to the interconnection using parameters (eg, header fields) to indicate either the type of communication service of origin (send) messages or the type of service of communication of receiver messages (receive), or both. The use of these parameters is optional and the main advantage of using said parameters (eg, fields, flags, indicators, etc.) is to minimize the required signaling made between different network elements when the interconnection between different types of service systems is performed. communication of messages. In addition, the receiving client be aware of the type of message communication service used in the originating client to connect different message communication services. In Figures 14 to 24, the use of parameters that refer to the use of reservation bits of the fields in the header portion of a message should be noted to specify the types of communication of source messages (send) and / or receiver (receive). This "addition" of a new field does not actually increase the overall size of the header, but rather one or more bits that were previously reserved in the related art are used as a new field to indicate the type of message communication service. Preferably, the parameters (fields, flags, indicators, etc.) can be added by the originating client, the originating message communication server or the receiver origin message communication services server, which will be described with greater detail later. Figure 14 depicts a flowchart of a method for interconnecting message communication services in accordance with an embodiment of the present invention using a receiver message communication services field and a message communication services field. origin. A field indicating the type of message communication service is added and the message is transmitted (S11), the message communication relay receives this message (S13) and checks whether a message type communication service field is found. included in the message. Here, it should be noted that a field of receiver message communication services and / or a field of origin message communication services can be included in the message. Preferably, said fields are included in the message by the originating client or the originating message communication server, or the source message communication services interconnection server. Preferably, the message communication relay first checks whether the message contains a receiver message communication services field (S15). If not,, the message communication relay reviews the type of message communication service that is to be received by the receiving client in relation to the user profile (S17). If the message contains a field of receiver message communication services or after the type of message communication service is checked from the user profile, the message communication relay converts (changes) the message through the transcoding unit to a message format that is supported on the receiving client (S19). Then, the message communication relay converts the message address through the address converter to an address format that is used by the receiver message communication server and also reviews the address of the next destination (S21). The message with address conversion is then transmitted to the receiver message communication server, which transmits the message to the receiving client (S23). The receiving client checks to see if there is a source message communication services field (S25). If so, the receiving client can review the type of message communication service of the originating client (S27). Otherwise, the receiving client can not perform said revision (S29). If the revision can be made, the receiving client can then transmit a reply message in response to the received message. The origin (sending) side that receives said reply (response) can then convert the format of the message communication service without having to review the user profile through the message communication relay. However, if a field of communication services of origin messages does not exist, the format of the message communication services must be subsequently converted in relation to the user profile that would contain information on the type of message communication service of origin. Figure 15 describes a signal flow for an interconnection method between respectively different message communication systems in a first embodiment of the present invention, wherein the originating client inserts the receiver message communication services field. Using a source-activated client, when a message is transmitted to a particular receiving client, the originating client checks, from a presence server, the message communication service that is established in the receiving client for reception (S31) and a receiver message communication services field is included with the message (S33). Here, the field of receiver message communication services is a field indicating the type of message communication service that may be received at that time by the receiving client. This can be achieved by setting one or more reserve bits in the header portion or body portion of the message, or by using an indication in another portion of the message. The message with the receiver message communication services field is then transmitted to the origin message communication server (OM1). The source message communication server stores the received message in a message store (storage) (IM5) and reviews the user profile for the information required to transmit the message (IM3), to subsequently review the address book and determine the address of the next destination to which the message should be sent (IM2). Then, the origin message communication server retrieves the message from the message storage (IM5) and transmits it to the source message communication services interconnection server (IMCN). Here, it should be noted that the source message communication server and the source message communication services interconnect server can be part of a single server or can be separate servers. The originating message communication services interconnect server cooperates with the address converter to check the address of the next destination of the message (IM2) and sends the message to the message communication relay to perform the interconnection of the message service (IM1) ). Here, the address converter can perform the same functions as those in the address book on the source side. The message communication relay reviews the type of message communication service in the receiving client in relation to the messaging message communication services field of the message and subsequently converts the format of the message communication service to be appropriate for the receiving client through the transcoding unit (IM4). If necessary (as shown by the dashed arrow line), the message communication relay can review the user profile for additional information from the receiving client other than the type of message communication service (IM3). The message communication relay cooperates with the address converter to convert the address of the receiving client included in the message to an address format that is used by the message communication service of the receiving client and reviews the address of the next destination to which the converted message must be transmitted (IM2). Then, the message communication relay transmits the converted message to the receiver message communication server (IM1). Here, the message communication relay can temporarily store a copy of the message until the message is successfully transmitted to the receiver message communication server. The copy of the message can be stored within the same message communication relay or in separate storage medium.

The receiver message communication server stores the received message in a message store of the receiver message communication server (IM5) and uses a notification message to notify the receiving client that a message has arrived (S35). Here, of the information necessary for the notification message, if there is information that must be supplied from the origin message communication server or the interconnection server of origin message communication services, then this can be received through a corresponding interface. In addition, message storage can be an internal part of the receiver message communication server or a separate entity. When reviewing the notification message, the receiving client requests the reception of the message (S37), the receiver message communication server then requests the message from the message storage (IM5), the storage of messages allows the message to be sent to the recipient. receiver message communication server (IM5) that then transmits the message to the receiving client (RM1). In the above manner, a message from the originating client that uses a certain type of message communication service may be transmitted appropriately to a desired receiving client using another type of message communication service, by means of which one or more message communication service parameters (eg, fields, flags, etc.) are used to improve the flow of signals between different network entities. Here, it should be noted that the above procedures can be performed in a sequence that is slightly different from that shown, if that is necessary or more desirable. Examples thereof are shown hereinafter. Figure 16 describes a signal flow for an interconnection method between respectively different message communication systems in a second embodiment of the present invention, wherein the origin message communication server inserts the message communication services field of receiver. Most of the procedures are the same as those in Figure 15, except for the procedures between the originating client and the origin message communication server. In particular, the originating client does not perform steps S31 and S33 of figure 15. Instead, the originating message communication server can review from a presence server, the message communication service that is established. in the receiving client for reception (shown with the dotted arrow line before reviewing the address book to determine the address of the next destination to which the message should be sent (IM2)) and the origin message communication server includes a field of communication services of receiver messages with the message (S4). All subsequent steps can be the same as those in Figure 5.

Figure 17 describes a signal flow for an interconnection method between respectively different message communication systems in a third embodiment of the present invention, wherein the source message communication services interconnect server inserts the service field of communication of receiver messages. Most of the procedures are the same as those in Figure 16. However, after the origin message communication server reviews the user profile in relation to the information necessary to transmit the message (IM3), the server Communication of origin messages first retrieves the message from the message storage (I 5), then revises the address book to determine the address of the next destination to which the message should be sent (IM2) and then transmits the message to the interconnection server of origin message communication services (IMCN). Later, the originating message communication service interconnect server can store the message in a message store on the receiving side (IM5) and the message communication service of the receiving client can be checked for the user profile (IM3) ). Then, the originating message communication services interconnect server cooperates with the address converter to review the next destination address of the message (IM2), retrieve the message from the message store (IM5) and add a service field of communication of messages from receiver to message (S51). All other subsequent steps may be the same as those in Figures 15 or 16. It should be noted that the originating message communication services interconnect server (or the origin message communication server connected to it) can also review the type of message communication service of the receiving client from the presence server (arrows with dotted line), in addition to reviewing the user profile. In addition, the field of receiver message communication services may be included in the header or other portions of the message. Figure 18 describes a signal flow for an interconnection method between respectively different message communication systems in a fourth embodiment of the present invention, wherein the origin message communication server inserts the message communication service field of origin. All procedures can be the same as those in Figure 15, except that the originating client adds a field of communication services of origin messages to the message (S61) before performing any other step and the receiving client can review the type of communication. Source message communication service (S67) at the end of the procedures. Furthermore, instead of obtaining information from the message communication service of the receiving client from the presence server (S31) and the optional step of referring to the user profile at the receiving side (IM3) of figure 15, it uses a presence server and, therefore, the information of the message communication service of the receiving client can be obtained by means of the message communication relay from the user profile on the receiving side (I 3). Figure 19 describes a signal flow for an interconnection method between respectively different message communication systems in a fifth embodiment of the present invention, wherein the origin message communication server inserts the message communication service field of origin. Most of the procedures are the same as those in Figure 18 but, instead of the originating client, the source message communication server adds a field of communication services from source messages to the message (S71) after performing the five initial steps (OM1, IM5, IM3, IM2, IM5), but before the step of transmitting the message (having the field of the originating message communication service) to the interconnection server of origin message communication services ( IMCN). Figure 20 describes a signal flow for an interconnection method between respectively different message communication systems in a sixth embodiment of the present invention, wherein the origin message communication service interconnect server inserts the service field of communication of origin messages. Most of the procedures are the same as those in Figure 19, but the originating message communication services interconnect server adds a field of origin message communication services to the message (S81) after receiving the message from the source message. source message communication server (IMCN) and cooperate with the user profile (IM3) and the address converter (IM2). All subsequent steps may be the same as those in Figure 19. Referring to Figures 15 to 20 explained above, it should be noted that certain signaling procedures described in various figures 1-24 can be implemented in the same procedure. In particular, certain features of Figures 15 to 20 may be combined or omitted if this is desirable. Figure 21 describes a format of a message having message communication service fields in accordance with the present invention. A field of receiver message communication services and a field of the source message communication service may optionally be included in the header portion of a message. Alternatively, the field of receiver message communication services and the field of the origin message communication service may optionally be included in other portions of a message, in addition to the header. Figure 22 describes an example of a portion of a Session Initiation Protocol (SIP) message header format in accordance with the present invention. The SIP is used during a session configuration (establishment) procedure to provide real-time multimedia data services. In the SIP message, an invitation message (INV, INVITE, in English) and an option field (OPT, Option Field, in English), as well as a header field of the message (MESSAGE, in English) have been defined recently to allow the field of the origin message communication service and the receiver message communication services field to be added to it. Figure 23 describes an example of a format for a Real-time Protocol (RTP) message header used to transmit real-time multimedia data in accordance with the present invention. The field of the origin message communication service and the receiver message communication services field must be added to it. Figure 24 describes an example of a format for a Real Time Transport Control Protocol (RTCP) message header used to control an RTP protocol in accordance with the present invention. The field of the origin message communication service and the receiver message communication services field must be added to the RTCP application header. Here, the length (size) of the field of the originating message communication service and the field of receiver message communication services to be added to RTP or RTCP can be adjusted accordingly accordingly.

As described above, the system and method for interconnecting messages of mobile communication terminals in accordance with the present invention, has the effect of allowing compatibility between different message communication systems, such as an instant message communication client and a client. of multimedia message communication services, so that multimedia content transmitted using a transmitting terminal that has an instant messaging client installed in that site can be received by a receiving terminal that has a multimedia message service client installed in that place. In addition, the message interconnection system and method of mobile communication terminals in accordance with the present invention, has the effect of allowing a sender to use the instant messaging client installed in his transmitting terminal to check whether certain receivers can receive services from multimedia messages. Additionally, by adding a field of origin message communication services and / or a field of receiver message communication services to the message, the procedures required to verify the type of message communication service can be minimized advantageously and the Signal traffic between network entities can be advantageously reduced. In addition, the receiving client may be aware of the type of message communication service used in the originating client, in order to perform the interconnection of different message communication services.
