Abstract

In order to prevent a user equipment, called UE hereinafter, from wasting unnecessary power, a method of reporting MBMS service information for the UE in a wireless communications system is provided. The method includes canceling reporting an MBMS message if there is no MBMS selected service in the UE upon entering a dedicated radio resource control state. Preferably, the MBMS message is an MBMS MODIFICATION REQUEST message.

Claims

1. A method of reporting multimedia broadcast multicast service, called MBMS hereinafter, service information in a user equipment, called UE hereinafter, of a wireless communications system, the method comprising:

canceling reporting an MBMS message if the UE has no MBMS selected service upon entering a dedicated radio resource control state.

2. The method of claim 1 further comprising reporting the MBMS message if the UE has at least one MBMS selected service upon entering the dedicated radio resource control state.

3. The method of claim 1, wherein the dedicated radio resource control state is a CELL_DCH state.

4. The method of claim 1, wherein the MBMS message is an MBMS MODIFICATION REQUEST message.

5. The method of claim 1, wherein the wireless communications system is a third generation communications system.

6. A communications device of a wireless communications system utilized for accurately reporting multimedia broadcast multicast service, called MBMS hereinafter, service information, the communications device comprising:

a control circuit for realizing functions of the communications device;

a central processing unit installed in the control circuit for executing a program code to operate the control circuit; and

a memory coupled to the central processing unit for storing the program code;

wherein the program code comprises;

canceling reporting an MBMS message if there is no MBMS selected service upon entering a dedicated radio resource control state.

7. The communications device of claim 6, wherein the program code further comprises reporting the MBMS message if there is at least one MBMS selected service upon entering the dedicated radio resource control state.

8. The communications device of claim 6, wherein the dedicated radio resource control state is a CELL_DCH state.

9. The communications device of claim 6, wherein the MBMS message is an MBMS MODIFICATION REQUEST message.

10. The communications device of claim 6, wherein the wireless communications system is a third generation communications system.
