Abstract

A cell broadcasting service system includes: a terminal for generating a short message service (SMS) type message and a cell broadcasting service (CBS) type message; an SMS center for transmitting a CBS type message to a CB center when receiving the CBS type message from the terminal; and a CB center for broadcasting a received message to a corresponding range area by referring to broadcast range information of the message when receiving the message from the SMS center. By assigning a CB ID to a specific subscriber group (a small circles or a local group), a general subscriber can broadcast a short message in the position of the CB entity. In addition, various get-together information and local information can be easily provided to subscribers of a group located within a broadcast range, and more efficient and substantial information can be provided at a low cost.

Claims

1. A cell broadcasting service system comprising:

a terminal for generating a short message service (SMS) type message and a cell broadcasting service (CBS) type message;

an SMS center for transmitting the CBS type message to a CB center when receiving the CBS type message from the terminal; and

a CB center for broadcasting a received message to a corresponding range area by referring to broadcast range information of the message when receiving the message from the SMS center.

2. The system of claim 1, wherein the CB center is connected to the SMS center by an interface of the same type as the interface with the CB entity.

3. The system of claim 1, wherein the terminal comprises:

a controller for generating a data burst message according to a determined processing routine after a message data is generated by a key input unit and the transmission method of the generated data is determined;

a CB message converter for converting a form of a certain message carried on the data burst message into a CBS type, if the determined transmission method is ‘

broadcast’

; and

a radio module for processing the generated data burst message so as to be wirelessly transmitted and transmitting it to a base station.

4. The system of claim 3, wherein if the determined transmission method is a point-to-point method, the form of the certain message carried on the data burst message has the SMS type.

5. The system of claim 1, wherein the terminal is assigned a cell broadcast identifier (CB ID).

6. The system of claim 1, wherein the terminal registers its address in the SMS center for a CBS authentication.

7. The system of claim 1, wherein the broadcast range is classified into a cell wide, a location area wide and a network wide.

8. A cell broadcasting service method comprising the steps of:

generating a message;

transmitting the generated message to an SMS center through a base station and an MSC;

transmitting a CBS type message of the messages transmitted to the SMS center, to a CB center; and

checking a broadcast range of the message transmitted to the CB center and broadcasting it to a corresponding range area through the MSC.

9. The method of claim 8, wherein the message generating step comprises:

inputting a message content to a terminal;

storing the inputted message in a memory;

determining a message transfer method;

inputting a CB ID and caller information and selecting a message broadcast range, if the determined transfer method is a ‘

broadcast’

;

converting the message form stored in the memory into a CBS type, if the broadcast range is selected; and

transmitting the converted message to a base station.

10. The method of claim 9, wherein if the determined transmission method is a point-to-point method, the inputted message is processed according to a general short message processing routine.

11. The method of claim 8, wherein the broadcast range is classified into a cell wide, a location area wide and a network wide.

12. The method of claim 9, wherein the terminal is assigned a cell broadcast identifier (CB ID).

13. The method of claim 9, wherein the terminal registers its address in the SMS center for a CBS authentication.

14. The method of claim 8, wherein the CB center is connected to the SMS center by an interface of the same type as the interface with the CB entity.
