Embodiment Construction

[0046] The radio resource control (RRC) connection establishment process refers to the process in which the user equipment (UE) initiates an RRC connection request message to the UTRAN in idle mode, and tries to establish an RRC connection with the UTRAN to enter the "connected mode". After the CMB function is introduced, the secondary common control physical channel (SCCPCH) in the cell will be divided into an SCCPCH carrying CMB services and an SCCPCH not carrying CMB services. However, during the establishment of the RRC connection, the UE and the radio network controller (RNC) select the SCCPCH according to the initial user equipment identity, so the SCCPCH carrying the CMB service may be selected according to the prior art solution.

[0047]Since in the connection establishment process, UE and RNC only select SCCPCH from system information block 5, therefore, in order to avoid common user connection establishment to select SCCPCH carrying CMB service, the present invention...

Abstract

The method broadcasts system information block 5 (SIB5) and system information block 6 (SIB6) to cell at same time. SIB6 includes slave complete common physical channels (SCCPCH) available to cell. SIB5 includes SCCPCH available to cell except the SCCPCH of carrying cell multibroadcast (CMB) channel. In connection procedure of radio resources control (RRC), User equipment and radio network controller (RNC) select same SCCPCH from SIB5 to transmit message respectively. In procedure for building RRC connection, the invention does not select SCCPCH of carrying CMB service so as to prevent influence on CMB service from procedure of building RRC connection of general user.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for avoiding interference with cell multicast (CMB) services. Background technique [0002] Products of WCDMA R99 and R4 protocol versions have been commercialized and can provide point-to-point live streaming and on-demand services for each user. However, the cost of on-demand services is very high, which limits the number of mobile TV users and greatly reduces commercial value. For this reason, the industry has launched a broadcast service carried on the Secondary Common Control Physical Channel (SCCPCH) (this invention is called cell broadcast service, namely CMB service), which can provide broadcast service in products of WCDMA R99 and R4 protocol versions. [0003] Since the CMB service is carried on the SCCPCH, the realization of the CMB function depends on whether the user equipment (UE) can select the correct SCCPCH according to the parameters configured by...
