Method for MCCH configuration obtaining by terminals in TD-SCDMA system

Abstract

The present invention provides a method for obtaining MCCH collocation by terminal in TD-SCDMA system. The terminal is switched from an original district to a target district. The method comprises the following procedures: transmitting a switching command which carries the information element identifying whether the MCCH collocation of target district is same with the MCCH collocation of original district by a network side to the terminal; receiving the switching command by the terminal for determining whether the MCCH collocation of the target district is same with the MCCH collocation of original district according to the information element in the switching command, if the collocation is same, continuing the using of the MCCH collocation of original district, and if the collocation is not same, obtaining the MCCH collocation of target district from the system information of target district. The method according to the invention settles the problem that the system information of new district after switching requires to be read after each switching when the terminal receives the multi-media broadcasting service through adding the indication showing whether the MCCH channel collocation is consistent before and after the terminal switching in the switching command based on the original switching flow path. The action of terminal is reduced and the operating efficiency of terminal is increased.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for a terminal to acquire MCCH configuration in a TD-SCDMA system. Background technique [0002] In Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, the traffic channel (MTCH) for transmitting multimedia broadcast service (MBMS) is configured and controlled by MBMS Control Channel (MCCH), and the configuration information of MCCH is controlled by The system information of the cell where the terminal resides is broadcast. The terminal reads the system information of the cell where it resides in the idle state, and stores the MCCH configuration in it. When the user needs to receive MBMS services, the terminal receives the MCCH channel according to the stored MCCH configuration information, thereby obtaining the MTCH configuration information. And receive the MBMS service on the MTCH according to the configuration information of the MTCH. Whil...

Problems solved by technology

However, in the current system, when a handover occurs, the terminal does not know whether the configuration of the MCCH channel of the cell before and after the handover is the same, and the handover command does not include the MCCH channel configuration information of the cell after the handover. To receive MBMS services, you have to read system messages repeatedly, which brings great complexity to the implementation and scheduling of terminals, and even affects users' experience of MBMS services
