Embodiment Construction

[0060] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0061] In view of the problems in the prior art, the present invention proposes a new method for realizing synchronization between RNCs, and the corresponding network architecture is as follows: Figure 5 Shown. As the current RNC generally reserves some idle Iub interface resources, you can consider making full use of these Iub interface resources, that is, connect SRNC and DRNC through the idle Iub interface. In this way, for MBMS services, through Certain processing is performed on the protocol process within the RNC to achieve synchronization between RNCs. The specific implementation of the method includes: configuring an RNC in the network as an SRNC, and configuring the respective service area information corresponding to different MBMSs to th...

Abstract

The invention discloses a method and a system for achieving synchronization among radio network controllers (RNC), wherein one of the RNC is configured as a service radio network controller (SRNC), and service regional information corresponding to different multimedia broadcast services (MBMS) is configured to the SRNC; a service center initiates an MBMS service and sends session start instructions to the SRNC and a destination radio network controller (DRNC) in a service region corresponding to the initiated MBMS service; and the SRNC establishes an Iub transmission link together with the DRNC in the service region corresponding to the initiated MBMS service and receives MBMS service data from the service center, and the established Iub transmission link and the DRNC in the service region corresponding to the initiated MBMS service are used to perform the synchronization. The invention discloses two devices for achieving the synchronization among the RNC at the same time. By applying the method, the system and the devices, the development capacity can be reduced and the development input can be cut down.

Description

Technical field [0001] The present invention relates to mobile communication technology, in particular to a method, system and equipment for realizing synchronization between radio network controllers (RNC, Radio Network Control). Background technique [0002] As an emerging multimedia service, Multimedia Broadcast Multicast Service (MBMS, Multimedia Broadcast Multicast Service) has attracted widespread attention in the industry and is regarded by the industry as a very promising application in the third generation of digital communications (3G, 3rd Generation). business. MBMS business means that mobile terminal users receive broadcast digital audio and video content, such as TV programs, in the form of channels or channels on mobile terminals with operating systems and video functions. [0003] Currently, for MBMS services in systems such as Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access), the conditions...
