Description

Method for providing multimedia messaging service in asynchronous 3G mobile communication network {Method for providing multimedia messaging service in WCDMA}

The present invention relates to a method for providing a multimedia messaging service (MMS) in a WCDMA system, which is an asynchronous third generation mobile communication network. The present invention relates to a method of transmitting an MMS message without changing a database in a WCDMA system by matching an MDN (or MSISDN) used when providing a messaging service.

Typically, switching centers of second and second generation mobile communication systems manage subscriber information by a home location register (HLR) and a visitor location register (VLR). Subscriber information includes a mobile identification number (MIN) and a mobile description number (MDN). The MIN generally refers to a subscriber's telephone number assigned to a mobile terminal by a number recognized by a user. The MDN is a number used by the system for subscriber management separately from the MIN and used for user authentication. In other words, MDN is used as a primary key when managing or referencing a database in the system. Currently, domestic carriers use MDN and MIN identically. Meanwhile, in the GSM system, a message is transmitted between a sender and a receiver by using a mobile station integrated services digital network (MSISDN) number. The MSISDN is usually the phone number of the mobile terminal.

Multimedia Messaging Service (MMS) is a service defined in the international standard recommendation 3rd Generation Partnership Project (3GPP) Technical Specification (TS) 22.140 and 23.140. It is a service to transmit and receive multimedia data.

The MMS presented in the standard recommendation adopts a store and forward method as a message transmission method. A multimedia message is sent encapsulated with media content, information needed to describe the media content, and address information identifying the recipient of the message. The multimedia message is transmitted from the sender terminal to the multimedia messaging service center (MMSC), which notifies the receiver terminal of the receipt of the message. The multimedia message stored in the multimedia messaging service center is transmitted to the receiver terminal by the receiver request.

1 shows a network configuration for transmitting a general multimedia message.

The second generation user terminal 11 is connected to the MMS relay 19 through the second generation mobile network 13, and the third generation user terminal 12 is connected to the MMS relay via the third generation mobile network 14. 19). The roaming MMS user terminal 15 is then connected to the MMS relay 19 via the mobile access network 16 and the Internet / IP network 18. The external server 23 and the wired email client 17 can also be connected to the MMS relay 19 via the Internet / IP network 18. An MMS server 20 and a user database DB are connected to the MMS relay 19. The MMS server 20 is connected with a message storage unit 21 for storing the received multimedia message.

As such, the second generation communication network and the third generation communication network are combined in the MMS message transmission system. Currently, the multimedia messaging service provided in the 2.5 generation communication network uses MDN information as a key for managing transmitted messages. In addition, the MMS-related standard recommends that MDN (or MSISDN) be used as the primary key for message management. However, in the WCDMA network, the third generation mobile communication network, a client ID is used to interwork infrastructure. The client ID uses not only inter-infrastructure interworking but also terminal. However, since the multimedia messaging service already served according to the standard recommendation uses MDN as the primary key for message management, there is no problem in providing the multimedia messaging service using the client ID. Therefore, an alternative is needed.

Accordingly, the present invention is to solve the problems of the prior art, by matching the client identifier (ID) used when inter-infrastructure in the WCDMA system and the MDN (or MSISDN) used to provide a multimedia messaging service, in the WCDMA system An object of the present invention is to provide a method for transmitting an MMS message without changing the database for storing multimedia messages.

According to an aspect of the present invention, there is provided a method for providing a multimedia messaging service in a WCDMA system, comprising: a first step of receiving, by a MMS server, a multimedia message from an originating terminal and storing the multimedia message in a database; Transmitting a notification message including an address of the MMS server to a receiving terminal; And a third step of retrieving the received multimedia message at the request of the receiving terminal and transmitting the received multimedia message to the receiving terminal, wherein the MMS server stores the client ID information in the header of the multimedia message received in the first step. Change to the corresponding MDN number and store in the database, and in the third step to change the client ID of the receiving terminal transmitted in the request of the receiving terminal to the corresponding MDN number, characterized in that for searching the database.

The present invention also provides a method for providing a multimedia messaging service in a WCDMA system, the method comprising: a first step of receiving, by a MMS server, a multimedia message from a calling terminal in a database; A second system for transmitting a notification message including an address of the MMS server to a receiving terminal; And a third step of retrieving the received multimedia message at the request of the receiving terminal and transmitting the received multimedia message to the receiving terminal, wherein the MMS server stores the client ID information in the header of the multimedia message received in the first step. Change to the corresponding MSISDN number and store in the database, and in the third step, the client ID of the receiving terminal transmitted when the request of the receiving terminal is changed to the corresponding MSISDN number to search for the database.

Hereinafter, with reference to the accompanying Figure 2 will be described in detail a preferred embodiment according to the present invention.

In the following description of the multimedia message transmission method according to the present invention will be omitted for the general technical content that can obscure the technical gist of the present invention. Further, the detailed description according to the present invention described below only describes one example, and it will be apparent to those skilled in the art that the present invention can be easily modified from the technical idea according to the present invention.

The following describes the case of uploading MMS message to MMS server under MMS 4.0 provided by 2.5G mobile communication network. When uploading a message in a general service case, MIN is used as the source information included in the message header. In the case of roaming services, IRM is included in the origination information of the message header when the message is uploaded. Meanwhile, when uploading a message from the originating terminal to the MMS server, the incoming information included in the message header includes the MDN.

Next, a case of downloading a multimedia message to a receiving terminal at the request of the receiving terminal will be described. When downloading a message stored in the message storage unit to the receiving terminal, the request message received from the receiving terminal includes the MIN information of the receiving terminal. In the domestic case, MIN and MDN are the same value, so it is not a problem in the management of a database for providing a multimedia service.

However, in the case of providing a multimedia messaging service in a WCDMA system, which is a third generation mobile communication network, all of the identification information included in the header of the multimedia message input to the MMS server is a client identifier (ID). That is, when uploading a multimedia message to the MMS server, the origination information included in the message header includes the client ID, and the incoming information includes the MDN (or MSISDN). When the receiving terminal requests to download the multimedia message stored in the MMS server, the information included in the request message received from the receiving terminal includes a client ID. Therefore, the MMS server cannot retrieve the stored multimedia message by designating the receiving terminal from the database when the receiving terminal downloads the request. This is because the reception terminal information is stored as the MDN when uploading to the database as described above.

In order to solve this problem, in the present invention, the MMS server is provided with an address matching table that matches the client ID and the MDN. That is, as shown in FIG. 2, the MMS server is provided with an address matching table in which client IDs, MINs, and MDNs are matched with each other.

The MMS server converts the client ID of the origination information included in the header of the multimedia message received through the MMS relay into an MDN value corresponding thereto, and stores the same in the message storage unit. When the download request is made by the receiving terminal, the MMS server converts a client ID included in the request message of the receiving terminal into an MDN corresponding thereto and searches for a database. Then, the retrieved multimedia message is transmitted to the client ID of the receiving terminal.

Let's look at this more specifically.

The calling terminal creates a multimedia message for transmission and transmits it to the MMS server. In this case, the origination information of the transmitted multimedia message includes the client ID of the originating terminal, and the reception information includes the MDN (or MSISDN) number of the receiving terminal. The originating MMS server identifies the receiving MMS server using the MDN number of the receiving terminal. At this time, the MMS server may check the client ID of the receiving terminal corresponding to the MDN number of the receiving terminal, and route the multimedia message to the receiving MMS server using the client ID. When the multimedia message is received, the receiving side MMS server notifies the receiving terminal that the message has been received by using the push access protocol server. The push access protocol server is a push gateway that pushes messages to mobile terminals using the WAP forum standard. The receiving terminal pulls the multimedia message received from the MMS server. At this time, the MMS server changes the client ID of the receiving terminal to the MDN number corresponding thereto, and searches for the message storage unit. The MMS server inserts the client ID of the receiving terminal into the retrieved MMS message and routes it to the receiving terminal through the MMS relay.

According to the present invention as described above, it is possible to provide a multimedia messaging service in a WCDMA mobile communication system without modifying a database built for an existing multimedia messaging service and satisfying the MMS standard recommendation.
