Point-to-Point Multimedia Information Service Providing Device and Method and Terminal {A APPARATUS AND METHOD FOR PROVIDING POINT-TO-POINT MULTI-MEDIA INFORMATION SERVICE ONLINE AND MOBILE STATION}

The present invention relates to an apparatus for providing a multimedia information service, a method and a terminal thereof, and more particularly, to a point-to-point multimedia information of a call capable of transmitting and displaying multimedia information including letters and numbers during a voice call with a counterpart. The present invention relates to a service providing device, a method thereof, and a terminal.

Short service was first proposed by the European Telecommunication Standard Institute (ETSI) to define a point-to-point service that can transmit and receive up to 155 bytes of characters between incoming and outgoing terminals for application to digital cellular communication systems in Europe. The characteristics of the short message service is that the short message can be delivered in the form of a database character by using the access channel and the paging channel as well as the traffic channel, so that the service can be performed regardless of the operating state of the terminal.

SMSC (Short Message Service Center) can be used in both GMS (Group Special Mobile) and IS-41C networks. SMSC is an independent node with its own SPC (Signalling Point Code) in SS7 (Signalling System 7) network.It is connected to Home Location Register (HLR) and Mobile Switching Center (MSC). It has the function of detecting the location of the receiver and delivering a short message to mobile subscribers through PLMN (Public Land Mobile Network).

The SMSC can transmit and receive numbers and letters bidirectionally between various text delivery systems (PC communication system, internet server system, mobile phone, etc.) and subscribers using a mobile communication network.

On the other hand, in the voice call service currently in service, information (eg, phone number, account number, etc.) that must be transmitted more easily by transmitting numbers or letters during a call with the other party must be transmitted through the caller's voice. Cases often occur. As a result, in addition to the difficulty in delivery according to the surrounding environment and the voice characteristics or listening ability of the individual, various problems such as time delays are caused.

The technical problem to be solved by the present invention is to solve such a problem, and not only can transmit multimedia information including numbers and letters to be transmitted during a voice call with the other party in real time, but also display the transmitted multimedia information. The present invention provides a device for providing a point-to-point multimedia information service, a method thereof, and a terminal.

In addition, by providing the multimedia information service between the calling party and the terminal to provide a point-to-point multimedia information service during the call that can provide turn-based games such as long-term, Baduk and algae, and real-time games such as StarCraft in the text chat between the called party An apparatus, a method thereof, and a terminal are provided.
