Abstract

A wideband code division multiple access (W-CDMA) user equipment (UE) for receiving a multimedia broadcast/multicast service (MBMS). The UE comprises an MBMS receiver configured to receive data of an MBMS service over one of a secondary common control physical channel (S-CCPCH) or a dedicated channel. After the reception of the data of the MBMS service over the one of the S-CCPCH or dedicated channel, configured to receive data of the MBMS service over the other of the S-CCPCH or dedicated channel.

Claims

1. A method for transferring multimedia broadcasts/multicast services (MBMS) in a wireless communication system, the method comprising:

determining a number of users in a cell to receive an MBMS service;

using the determined number of users and cell condition information to determine whether a dedicated channel or a shared/common channel is to be used for the MBMS service;

receiving MBMS data; and

mapping the MBMS data to the determined dedicated or shared/common channel;

wherein the determined dedicated or shared/common channel is at least based on a threshold test, wherein on a condition that the determined number of users is below a threshold, a dedicated channel is used for the MBMS and on a condition that the determined number of users is above the threshold, a shared/common channel is used for the MBMS, and wherein the shared/common channel includes a secondary common control physical channel (S-CCPCH).

2. The method of claim 1, wherein on a condition that the determined number of users is equal to or below the threshold, a dedicated channel is used for the MBMS.

3. The method of claim 1, wherein the cell condition information includes expected congestion of the cell.

4. The method of claim 1, wherein the dedicated channel is a dedicated shared channel and the shared/common channel is a common shared channel.

5. The method of claim 1, wherein the dedicated channel is a dedicated high speed shared channel and the shared/common channel is a common high speed shared channel.

6. The method of claim 1, wherein determining the dedicated channel or shared/common channel and mapping the MBMS data onto the determined dedicated channel or shared/common channel is repeated during an MBMS service.

7. The method of claim 1, wherein the method is implemented in a radio network controller (RNC).

8. The method of claim 7, wherein the RNC is a controlling RNC (C-RNC).

9. A radio network controller (RNC) for transferring multimedia broadcasts/multicast services (MBMS) in a wireless communication system, the method comprising:

circuitry configured to determine a number of users in a cell to receive an MBMS service;

circuitry configured to use the determined number of users and cell condition information to determine whether a dedicated channel or a shared/common channel is to be used for the MBMS service;

circuitry configured to receive MBMS data; and

circuitry configured to map the MBMS data to the determined dedicated or shared/common channel;

wherein the determined dedicated or shared/common channel is at least based on a threshold test, wherein on a condition that the determined number of users is below a threshold, a dedicated channel is used for the MBMS and on a condition that the determined number of users is above the threshold, a shared/common channel is used for the MBMS, and wherein the shared/common channel includes a secondary common control physical channel (S-CCPCH).

10. The RNC of claim 9, wherein on a condition that the determined number of users is equal to or below the threshold, a dedicated channel is used for the MBMS.

11. The RNC of claim 9, wherein the cell condition information includes expected congestion of the cell.

12. The RNC of claim 9, wherein the dedicated channel is a dedicated shared channel and the shared/common channel is a common shared channel.

13. The RNC of claim 9, wherein the dedicated channel is a dedicated high speed shared channel and the shared/common channel is a common high speed shared channel.

14. The RNC of claim 9, wherein determining the dedicated channel or shared/common channel and mapping the MBMS data onto the determined dedicated channel or shared/common channel is repeated during an MBMS service.

15. The RNC of claim 9, wherein the RNC is a controlling RNC (C-RNC).
