Description

Method and system for message transfer in mobile communication terminal

The present invention relates to a message transmission method and system in a mobile communication terminal, and more particularly, to a message transmission method and system in a mobile communication terminal based on terminal mobility between operators.

With the rapid spread of mobile phones, the population of text service users is increasing rapidly. On the other hand, the text service of the mobile phone, unlike the e-mail can be delivered almost at the same time as the point of delivery, because it is already firmly established as one of the current communication means.

SMS (Short Message Service) is basically provided with a function to send a reply number and a message between the terminals, you can know the weather forecast news, stock information, etc. In addition, the customer can directly search a variety of information to select only the necessary information It may be. In addition, it is possible to send and receive e-mails through Internet and PC communication, and to provide various information retrieval services necessary for daily life.

In addition, since the information is provided interactively for the convenience of the user, it is increasing in the number of middle-aged and middle-aged people who are not only teenagers but also the use of information in that anyone can easily use it. In Korea, credit card companies continue to expand their use of electronic payments and e-commerce, including the introduction of a service that sends a text message to approve transactions to prevent card accidents.

MMS stands for Multimedia Message Service, which is a method of accumulative transmission of graphics, video clips, sound files, and short text messages over a wireless network using the Wireless Application Protocol (WAP) protocol.

In addition, MMS recently attracted attention as it emerged as an issue at the 3rd Generation Partnership Project 2 (3GPP2) meeting, which is a synchronous 3G mobile communication standards consultative body. MMS also supports sending email directly to an email address. The most common use of MMS is communication between mobile phones. Therefore, nowadays, MMS is defined as a next-generation message service that sends and receives multimedia files such as video, photo, and voice message using a mobile phone. MMS is expected to be used more because the short messaging service (SMS) can deliver a large amount of messages such as multimedia, unlike simple text messages.

Currently, SMS and MMS in Korea have been using the unique non-standard standard which has been inherited since the CDMA era, and the reason for the non-standard origin is the Korean code system which is the basis of SMS and MMS.

That is, the Korean Hangul code system is KSC5601, but the Hangul code system in the international standard is defined as Unicode. Accordingly, domestic telecommunication operators have written their own data coding schemes representing KSC5601. (For example, A carrier is 0x0C, B operator is 0x84)

In addition, in the case of MMS, the multimedia expression method of MMS has been developed differently between operators.

Currently, with the introduction of WCDMA, subscribers have been using only USIM cards to change their handsets.

However, for example, when a subscriber B carrier (IM carrier USIM) attempts to receive SMS and MMS services from the carrier B network using the carrier A terminal, the message carrier provided by the SMSC and MMSC in the carrier B's network is provided. Since the terminal is not recognized, there is a problem that SMS and MMS cannot be used when there is terminal mobility between providers.

2 is a diagram illustrating a message transmission method and system based on terminal mobility between providers according to an embodiment of the present invention. More specifically, FIG. 2 is a diagram for describing a method and system for transmitting an SMS to a subscriber who has not been moved by a subscriber who has been moved by a terminal in a service network of the same operator. That is, FIG. 2 is a diagram for describing a method and system for transmitting a SMS to a B communication company subscriber using a B communication terminal by a B communication company subscriber using a A communication terminal in a B communication company network.

First, the B carrier subscriber using the A carrier terminal 270 sends an SMS to the B carrier subscriber using the B carrier terminal 250. Here, the A communication company terminal 270 transmits to the unique SMSC address. The unique SMSC address is the SMSC address of the unique carrier corresponding to the message format of the terminal. The unique SMSC address may be stored in a ROM of the terminal or released in a USIM card. The SMSC address has a form similar to a general subscriber number and, when an outgoing call is made, is detected by the network and routed to the corresponding SMSC. That is, the A communication company terminal is a terminal of the B communication company subscriber, but transmits the SMS to the A communication company SMSC 230 through the SMSC gateway 300 (S210). Here, when the SMS sent by the A communication company terminal 270 is transmitted to the B communication company SMSC, the B communication company SMSC 200 cannot receive the SMS because the unique SMSC address of the A communication company terminal cannot be determined.

Therefore, when the SMSC address is stored in the USIM card and released, the B-communicator USIM 280 stores and releases the SMSC address of the B-communicator, so that the A-communicator terminal 270 and the B-communicator USIM card 280 are released. The subscriber using the service provider manually converts the B carrier SMSC address stored in the USIM card to the A carrier SMSC address through the user interface of the terminal, or requests the B carrier to automatically transmit the A carrier of the A carrier through the OTA function of the USIM card. Can be changed to SMSC address.

Since the method for changing the SMSC address in the USIM card is a technique known to those skilled in the art, a detailed description thereof will be omitted.

Subsequently, the A communication company SMSC 230 determines that the SMS received from the A communication company terminal 270 of the B communication company subscriber is an SMS transmitted to the B communication company subscriber using the called number, and the B communication company SMSC through the SMSC gateway 300. It transmits to 200 (S220).

Subsequently, the B communication company SMSC 200 converts the SMS received from the A communication company SMSC 230 into a B standard recognized by the B communication company terminal 250 and transmits the message to the B communication company terminal 250 (S230).
