[0030] The first embodiment mainly describes the scenario that when the UE in the cell idle state (CELL_IDEL) is receiving MBMS services on frequency F1, the UE wants to initiate dedicated services such as AMR calls and PS data services.

[0031] In the above case, if UE has the ability to receive MBMS service and dedicated service at the same time, UE will send RRC connection request (RRC CONNECTION REQUEST) to RNC, and RNC will configure dedicated resources for dedicated service after receiving the request. If the UE only supports one carrier at a time, the RNC needs to know the MBMS service ID (ID) and obtain its carrier frequency, and then the RNC can configure dedicated services on the MBMS service frequency. If the UE is capable of receiving multiple carriers, the RNC needs to know the MBMS service ID and obtain its carrier frequency, and then the RNC configures the dedicated service resources required by the UE according to the MBMS frequency and capability that the UE w...

[0041] The second embodiment mainly describes the scenario where the UE in the cell dedicated channel (CELL_DCH) or cell forward access channel (CELL_FACH) state is receiving CS / PS services and the UE wants to receive MBMS services.

[0042] figure 2 It is a schematic flow chart of the second embodiment of the present invention. refer to figure 2 , the flow process of the second embodiment of the present invention is as follows:

[0043] Step 201, the UE judges whether the frequency of the MBMS service to be received is the same as the frequency used by the current dedicated service, if it is the same, then the UE receives the MBMS service at the frequency of the MBMS service, and this process ends; if not, then execute step 202 and its steps next steps.

[0044] Step 202, the UE judges whether it can receive the MBMS service according to its own carrier capability, that is, judges whether receiving the dedicated service and the MBMS service at different frequencies at the ...

Abstract

The invention provides a method for realizing the concurrent of broadcast / multicast service. The method comprises: the user equipment (UE) transmits the frequency ID indicating the broadcast / multicastservice to the radio network controller (RNC); RNC obtains the frequency of the broadcast / multicast service based on the ID and configures the specific service to the frequency resource of the broadcast / multicast. The invention also provides a system realizing the broadcast / multicast service and the specific service development, comprising UE and RNC. Because UE in the inventive embodiment transmits the ID indicating the operating frequency of the broadcast / multicast service to RNC at the network, RNC acquires the frequency of the broadcast / multicast service based on the ID and configures thespecific service to the frequency resource of the broadcast / multicast service so as to lead UE to receive broadcast / multicast service and specific service at the same frequency and realize the development of the broadcast / multicast service and the specific service.

Description

technical field [0001] The invention relates to the technical field of time division duplex (TDD), in particular to a method and system for realizing concurrent broadcast / multicast services and dedicated services. Background technique [0002] In the current N-frequency Low Chip Rate (LCR) Time Division Duplex (TDD) standard, in order to support a wider range of broadcast services, such as broadcast / multicast (MBMS) services, the standard proposes that multiple A physical transmission channel carrying broadcast / multicast services on a carrier. A user equipment (UE) can receive broadcast / multicast services in any radio resource control (RRC) state. In addition, the UE may be capable of receiving concurrent services, for example, broadcast / multicast services and dedicated services such as Adaptive Multi-Rate (AMR) calls, Packet Switched (PS) data, etc. can be received simultaneously. When the UE has the ability to simultaneously receive MBMS services and dedicated services ...
