Problems solved by technology

[0007] The technical problem to be solved by the present invention is that in the TD-SCDMA multi-carrier frequency system, because the configuration of the existing non-MBMS service and MCCH does not meet the conditions of different frequency interval time slots, the terminal cannot read the MCCH and thus cannot obtain the MBMS service configuration information, resulting in users being unable to enjoy MBMS services

Embodiment 1

[0052] In this embodiment, multiple MCCHs in a cell are carried independently by using their respective common transmission channels.

[0053] When the cell is established, the RNC sends a common transport channel establishment request (CTCSREQ, COMMON TRANSPORT CHANNEL SETUPREQUEST) to the base station for each MCCH in the current cell to establish an Iub bearer. The message carries the frequency point where the MCCH is located. See CCSA>Description; the base station responds to the RNC with a common transmission information establishment response (CTCSRES, COMMON TRANSPORT CHANNEL SETUPRESPONSE), and the information element refers to the description of CCSA >;

[0054] The RNC sends a system broadcast message, wherein the system information block 5 (SIB5) carries the MCCH configuration information of the cell, and the configuration information includes related physical resources such as frequency points configured by the MCCH and corresponding time slot channelization codes; ...

Embodiment 2

[0076] In this embodiment, multiple MCCHs in a cell use a common transmission channel to share bearer. In fact, after the RNC in Embodiment 1 establishes at least one Iub bearer with the base station, the shared bearer of the common transport channel can be established through this embodiment.

[0077] When the cell is established, the RNC sends a common transport channel establishment request CTCSREQ to the base station for each MCCH in the current cell to establish an Iub bearer. The message element refers to the description of CCSA>, and the message carries the broadcast reference (BR, Broadcast Reference) information element, this information element uniquely identifies a common transmission channel that can bear the weight of multiplexing in the RNC; If the base station judges not to carry out the multiplexing of the MCCH channel Iub, then the base station responds to the RNC with public transmission information to set up a response CTCSRES, See CCSA> description for the ...

Abstract

The invention relates to a method for receiving and transmitting a multimedia broadcast / multicast service control message, which is suitable for a terminal of a TD-SCDMA system in a dedicated connection to acquire configuration information of an MBMS. The method comprises the steps that: an RNC transmits a public transmission channel establishing request corresponding to an MCCH of the system configuration to a base station; the RNC transmits a system broadcast message after the base station successively establishes a public transmission channel, wherein the system broadcast message carries MCCH configuration information of each frequency point of a multi-carrier system; the RNC transmits an MBMS control message to the MCCH of each frequency point; and the terminal monitors the MCCH of any carrier in a cell according to the capacity to acquire the configuration information of the MBMS. The method for receiving and transmitting the multimedia broadcast / multicast service control message widens the ways for the terminal to acquire the configuration information of the MBMS, and improves the service quality of the system.

Description

technical field [0001] The present invention relates to a method for sending service control messages in a third generation mobile communication system, in particular to a method for sending and receiving control messages of Multimedia Broadcast / Multicast Service (MBMS) in a multi-carrier communication system. Background technique [0002] MBMS bearer modes are generally divided into two types: point-to-point (PTP, Point To Point) bearer and point-to-multipoint (PTM, Point To Multipoint) bearer. Wherein, the configuration of the PTM service bearer is configured to the terminal by the radio network controller (RNC, Radio Network Controller) through the MBMS Control Channel (MCCH, MBMS Control Channel). For the network structure, refer to figure 1 , and the physical resources used by the MCCH are configured through a system information block 5 (SIB5, System Information Block5). [0003] For terminals supporting MBMS, according to 25.331 of the 3rd Generation Partnership Proje...
