Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] The present invention uses protocol entity MAC_mt in the SRNC to manage the CFN calculation and distribution of the MBMS services of each cell under the SRNC and each cell under the DRNC in the MBMS service area, so that the SFN of the data sent by each cell is consistent, the implementation is simple, and the system is simplified signaling control process.

[0033] The invention provides a method for realizing synchronous sending between RNCs, comprising the following steps:

[0034] A. A group of RNCs belonging to the MBMS service synchronization area are configured as SRNC and DRNC;

[0035] B. The SRNC manages the sending of the MBMS service data frame through the protocol entity MAC_mt, so as to realize synchronous sending of the MBMS service in the MBMS service synchronization area.

Abstract

The invention discloses a method for implementing synchronous transmission between RNCs, which comprises the following steps that: a group of RNCs belonging to an MBMS service synchronizing area are configured as SRNCs and DRNCs; and the SRNCs manage the transmission of SBMS service data frames through a protocol entity MAC_mt to implement the synchronous transmission of MBMS service in the MBMS service synchronizing area. The invention also discloses a system and a device for implementing synchronous transmission between RNCs. In the technical scheme, the synchronization between the RNCs through interaction of Iur interface user planes can be implemented; and compared with the conventional synchronization method, in the method, signaling interaction between Iur interfaces is greatly decreased, problems that the implementation of the synchronization between the RNCs requires to increase a large number of signaling control flows, and the implementation process is complicated in the prior art are solved.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular, the present invention relates to a method, system and equipment for realizing synchronous transmission between RNCs. Background technique [0002] MBMS (Multimedia Broadcast Multicast Service, multimedia broadcast multicast service) is a multimedia broadcast multicast function defined in 3GPP (3rd Generation Partnership Project, third generation partnership project). MBMS technology is mainly based on the existing CDMA (Code Division Multiple Access, Code Division Multiple Access) system, which enhances the original message broadcast function and provides point-to-multipoint one-way multimedia service technology, so as to realize network resource sharing and improve network quality. resource utilization. MBMS supports two modes of multimedia broadcasting service and multicasting service. It can not only broadcast multimedia video information directly to all users, but a...
