Abstract

The present invention relates to a transmission and reception device and a method for transmitting a point-to-point message through a broadcast type short message path, which is generated by generating a point-to-point message of several types of broadcast types and generating an identifier indicating that the point-to-point message is a broadcast control layer. The identifier and the point-to-point messages of the various layers are transmitted through the path of the broadcast message. Next, when a message is received through the broadcast message path, the broadcast type control layer determines whether there is an identifier, and if there is an identifier, transmits the message to the point-to-point message processor, and processes and displays the received point-to-point message. do. By doing so, a point-to-point message can be simultaneously transmitted to a plurality of terminals using a passage of a broadcast message.

Description

Point-to-point message transmitting and receiving device and method {A communication system of a point-to-point over broad cast and a control method

The present invention relates to a mobile communication device and method, and more particularly, to an apparatus and method for transmitting and receiving a point-to-point message for transmitting and receiving a point-to-point message.

The change of mobile communication technology has evolved from analog to 2G (2nd generation) digital method, and mobile communication service is changing from voice based to data communication, and from data communication to high speed multimedia service. Second generation digital systems include GSM using TDMA technology and IS-95A / B system using CDMA technology.

Mobile communication will evolve from the second generation to the third generation again, and high-speed data-only third generation mobile communication technology enables high-speed multimedia services.

Short messages that are currently commercially available include broadcast type short messages and point-to-point short messages. The broadcast short message is a method of sending a message to a terminal included in a specific cell or all cells specified in a network, and transmits a message through a paging channel or a broadcast control channel. Point-to-point messages are messages in a one-to-one manner, in which a user specifies a recipient and sends a short message. Point-to-point messages are transmitted from a network to a terminal using a paging channel or a traffic channel.

However, if you want to send a well-organized point-to-point message to multiple people so that everyone can share it, there is a disadvantage that you need to specify the receiving number of everyone.

Next, the operation of the point-to-point message transmission and reception apparatus according to the embodiment of the present invention having such a configuration will be described in detail.

First, the content provider server 600 of the service provider provides the content, and requests the short message center 500 to generate the content as a point-to-point message and transmit it through the broadcast channel.

Then, the interface interworking unit 550 of the short message broadcasting center unit 500 transmits the requested content to the broadcasting type message generating unit 530.

Then, the broadcast type message generator 530 generates a point-to-point message and an identifier, and the broadcast type broadcast control layer message generator 531 generates various types of control information except for the? The service layer message generator 532 generates a point-to-point message of a broadcast type tele service layer, and the other broadcast type message generator 534 generates a point-to-point message of another layer. Here, the other layers include a relay layer, a link layer, and a transport layer, and since such layers are well known in the art, a detailed description thereof will be omitted.

Meanwhile, the identifier generator 533 generates an identifier indicating that the message is a point-to-point message of the broadcast control layer.

The messages of the various layers generated as described above are transmitted to the broadcast type message splitting unit 540, like the identifier, and the broadcast type message splitting unit 540 may determine the size of the generated message and transmit the message as a single message. If the size is not available, it is divided and transmitted.

Then, the broadcast message transmitter 520 transmits the generated point-to-point message through the broadcast path.

Then, the message is converted into a protocol suitable for the public network through the protocol interworking unit 510, and the message is transmitted through the broadcast message path of the exchange 300 and the base station 100.

A signal converted and transmitted from the base station 200 to the radio is received by a plurality of terminals, where the reception operation is as follows.
