Abstract

A method and apparatus for providing and receiving a plurality of services via a single channel in a mobile communications system is provided, by which a plurality of the services can be effectively provided via the single channel.

Claims

1. A method of receiving a cell broadcast service in a mobile terminal adapted for use in a wireless communication system, the method comprising:

receiving, through a first channel, periodic information associated with receiving a message having a cell broadcast service (CBS) indication;

receiving, through a second channel, the message having the CBS indication, the message periodically provided and received in response to the periodic information; and

receiving CBS data in response to the CBS indication.

2. The method of claim 1, wherein the first channel is a broadcast control channel.

3. The method of claim 1, wherein the second channel is a point-to-multipoint channel.

4. The method of claim 1, further comprising periodically receiving the second channel.

5. The method of claim 1, further comprising receiving the CBS data via a point-to-multipoint channel.

6. The method of claim 5, wherein the point-to-multipoint channel is a cell broadcast traffic channel.

7. The method of claim 1, wherein receiving the message having the CBS indication comprises receiving a point-to-multipoint information message.

8. The method of claim 1, wherein receiving the message having the CBS indication comprises receiving a broadcast control scheduling message.

9. The method of claim 1, wherein the first channel is a point-to-multipoint control channel.

10. The method of claim 1, wherein receiving the message having the CBS indication comprises receiving during a modification period and receiving the CBS data comprises receiving during a corresponding modification period.

11. A method of communicating a cell broadcast service in a wireless communication system, the method comprising:

transmitting, through a first channel, periodic information associated with transmitting a message having a cell broadcast service (CBS) indication;

transmitting, through a second channel, the message having the CBS indication, the message provided periodically and corresponding to the periodic information; and

transmitting CBS data corresponding to the CBS indication.

12. The method of claim 11 wherein the first channel is a broadcast control channel.

13. The method of claim 11 wherein the second channel is a point-to-multipoint channel.

14. The method of claim 11 wherein transmitting the CBS data comprises transmitting via a point-to-multipoint channel.

15. The method of claim 14, wherein the point-to-multipoint channel is a cell broadcast traffic channel.

16. The method of claim 11 wherein transmitting the message having the CBS indication comprises transmitting a point-to-multipoint information message.

17. The method of claim 11 wherein transmitting the message having the CBS indication comprises transmitting a broadcast control scheduling message.

18. The method of claim 11 wherein the first channel is a point-to-multipoint control channel.

19. The method of claim 11 wherein transmitting the message having the CBS indication comprises transmitting during a modification period and transmitting the CBS data comprises transmitting during a corresponding modification period.

34. The method of claim 14, wherein the point-to-multipoint channel is a cell broadcast traffic channel.

20. A mobile terminal adapted for use in a wireless communication system, the mobile terminal comprising:

an antenna unit adapted to receive RF signals containing periodic information associated with receiving a message having a cell broadcast service (CBS) indication, the message having the CBS indication and CBS data;

an RF unit adapted to process the RF signals received by the antenna;

a keypad for inputting information from a user;

a storage unit adapted to store the periodic information, the cell broadcast CBS indication and the CBS data;

a display adapted to convey information to the user; and

a processing unit adapted to process the periodic information received through a first channel, process the message having the CBS indication received through a second channel and process the CBS data,

wherein the message having the CBS indication is periodically received and processed in response to the periodic information and the CBS data is processed in response to the CBS indication.

21. The mobile terminal of claim 20, wherein the first channel is a broadcast control channel.

22. The mobile terminal of claim 20, wherein the second channel is a point-to-multipoint channel.

23. The mobile terminal of claim 20, wherein the processing unit is further adapted to periodically process the second channel.

24. The mobile terminal of claim 20, wherein the processing unit is further adapted to process the CBS data via a point-to-multipoint channel.

25. The mobile terminal of claim 24, wherein the point-to-multipoint channel is a cell broadcast traffic channel.

26. The mobile terminal of claim 20, wherein the processing unit is further adapted to process a point-to-multipoint information message comprising the message having the CBS indication.

27. The mobile terminal of claim 20, wherein the processing unit is further adapted to process a broadcast control scheduling message comprising the message having the CBS indication.

28. The mobile terminal of claim 20, wherein the first channel is a point-to-multipoint control channel.

29. The mobile terminal of claim 20, wherein the processing unit is further adapted to process the message having the CBS indication during a modification period and to process the CBS data during a corresponding modification period.

30. A network for providing a point-to-multipoint service to at least one mobile terminal, the network comprising:

at least one transmitter adapted to transmit signals containing periodic information associated with transmitting a message having a cell broadcast service (CBS) indication, the message having the CBS indication and CBS data;

a CBS unit adapted to generate the CBS data; and

a controller adapted to control the at least one transmitter to transmit the periodic information through a first channel, transmit the message having the CBS indication through a second channel and transmit the CBS data,

wherein the message having the CBS indication is periodically provided and the CBS data corresponds to the CBS indication.

31. The network of claim 30 wherein the first channel is a broadcast control channel.

32. The network of claim 30 wherein the second channel is a point-to-multipoint channel.

33. The network of claim 30 wherein the controller is further adapted to transmit the CBS data via a point-to-multipoint channel.

35. The network of claim 30 wherein the controller is further adapted to include the message having the CBS indication in a point-to-multipoint information message.

36. The network of claim 30 wherein the controller is further adapted to include the message having the CBS indication in a broadcast control scheduling message.

37. The network of claim 30 wherein the first channel is a point-to-multipoint control channel.

38. The network of claim 30 wherein the controller is further adapted to transmit the message having the CBS indication during a modification period and to transmit the CBS data during a corresponding modification period.
