Abstract

A system for broadcasting wireless data service in a mobile communication system includes sending a request call for a wireless data service from a mobile terminal to a mobile switching center, identifying whether the terminal is registered in the mobile switching center, transmitting authentication code information indicating that the terminal is registered in the base transceiver station, and releasing the corresponding call in the terminal receiving the authentication code information and receiving the wireless service data. The authentication code information may include a Walsh code and a long code necessary for allowing the terminal to reconstitute the data. Through this case information, the system can broadcast wireless service data throughout an entire region and be assured that only mobile terminals storing compatible code information will be able to access the data.

Claims

1. A system for providing wireless data services, comprising:

a terminal which transmits a request for a broadcast wireless data service;

a mobile communication system which determines whether a subscriber of the terminal is authorized to receive the service, and which assigns a resource for providing the service if the subscriber is authorized; and

a broadcast center for providing the service.

2. A method for providing wireless data services, comprising:

receiving wireless data from a broadcast center at a predetermined time or date in a mobile switching center of a mobile communication system;

determining whether an authentication process of the wireless data is necessary, and if the authentication is required, assigning an encryption code and an authentication code;

transmitting the encryption code and the authentication code to a base transceiver station, and transmitting the wireless data from the broadcast center to the base transceiver station; and

broadcasting the wireless data received in the base transceiver station to a communication area.

3. The method of claim 2, wherein the base transceiver station enciphers the wireless data using the encryption code received from the mobile switching center and broadcasts the data.

4. The method of claim 2, wherein the wireless data received from the mobile switching center is broadcast to the communication area, if the authentication process of the wireless data is not required.

5. The method of claim 2, further comprising:

receiving a request call for a broadcast wireless data service from a mobile communication terminal in the base transceiver station, determining whether to broadcast the wireless data, and in the case of broadcasting the wireless data, transmitting the request call for the broadcast wireless data service to the mobile switching center;

determining whether the corresponding mobile communication terminal is registered in the mobile switching center, and informing the determination result to the base transceiver station;

identifying whether the mobile communication terminal received from the mobile switching center is registered in the base transceiver station, and if registered, transmitting the authentication code information and the encryption code information to the corresponding mobile communication terminal; and

receiving the wireless data service broadcast using the authentication information and the encryption code received in the mobile communication terminal.

6. The method of claim 5, further comprising:

transmitting a message to the terminal in the communications area indicating that the wireless data service is not available from the base transceiver station, if the mobile communication terminal is not registered.

7. The method of claim 5, further comprising:

transmitting a message to the terminal indicating that the wireless data is broadcasting at present, and querying whether the mobile communication terminal uses the broadcast wireless data;

sending a result of the query to the mobile switching center to determine whether the mobile communication terminal is registered, in the case of identifying that the broadcast wireless data is used in the mobile communication terminal; and

transmitting an authentication code and an encryption code to the corresponding mobile communication terminal and providing the wireless data service, in the case that the mobile communication terminal is registered.

8. The method of claim 5, further comprising:

transmitting a message to the terminal indicating that the wireless data service is not available, if a request call for the wireless data service by the terminal is received during a time when the wireless data is not broadcasting.

9. The method of claim 2, wherein the base transceiver station broadcasts the wireless data at the maximum electricity power, so that a plurality of subscribers receive the wireless data service in the communication area.

10. The method of claim 5, further comprising:

receiving the wireless data service in the mobile communication terminal;

receiving the wireless data broadcast from the base transceiver station; and

reconstituting and displaying the received wireless data using the authentication code and the encryption code received from the base transceiver station.

11. The method of claim 2, wherein the mobile switching center withdraws assigned encryption code and authentication code after the wireless data broadcasting transmitted from the broadcast center is finished.

12. The method of claim 2, wherein the wireless data broadcasting is transmitted in a standardized format set in the system, and data is assigned in a predetermined sequence and transmitted including the corresponding information.

13. The method of claim 2, wherein data with any errors in the sequence is disregarded, and data in a next sequence is sequentially processed if hand-offs or duplicate errors or losing errors occur in the mobile communication terminal while receiving the wireless data service.

14. A method for broadcasting information in a communications system, comprising:

receiving a request for wireless service data from a mobile terminal;

determining whether said mobile terminal is authorized to receive the wireless service data; and

broadcasting the wireless service data in an area which includes said mobile terminal, wherein the broadcasting step includes broadcasting code information with the wireless service data which only allows authorized terminals including said mobile terminal to access the wireless service data in said area.

15. The method of claim 14, wherein said determining step includes:

searching a database for information corresponding to said mobile terminal or a user of said mobile terminal; and

determining whether said mobile terminal is authorized to receive the wireless service data based on a result of the searching step.

16. The method of claim 14, further comprising:

determining whether the wireless service data is a pay service,

wherein if the wireless service is determined to be a pay service, the broadcasting step further includes encrypting the wireless service data with information which can only be decrypted by authorized terminals including said mobile terminal.

17. The method of claim 14, wherein the wireless service data is broadcast at a predetermined time.

18. The method of claim 17, wherein the predetermined time includes a predetermined time of day.

19. The method of claim 14, wherein the wireless service data is broadcast continuously throughout a predetermined period.

20. The method of claim 14, wherein when the broadcasting step is completed, said code information is re-assigned for use in transmitting other wireless service data.

21. A system for broadcasting information in a communications system, comprising:

a transceiver which receives a request for wireless service data from a mobile terminal; and

a processing unit which determines whether said mobile terminal is authorized to receive the wireless service data and broadcasts the wireless service data in an area which includes said mobile terminal, said processing unit broadcasting code information with the wireless service data which only allows authorized terminals including said mobile terminal to access the wireless service data in said area.

22. The system of claim 21, wherein said processing unit includes:

a processor which searches a database for information corresponding to said mobile terminal or a user of said mobile terminal, said processor determining whether said mobile terminal is authorized to receive the wireless service data based on a result of the database search.
