[0028] However, those skilled in the art know that before the SRNC sends the MBMS Sync Bear SetupRequest message to the RNC, it first needs to establish a communication link with the RNC, and then utilize the established communication link to send the MBMS Sync Bear Setup Request message; The number of RNCs in a certain service area usually only accounts for a small part of the number of all RNCs in the entire network, that is to say, most of the communication links established by SRNC are useless, thus causing a serious shortage of link resources. waste

Embodiment Construction
[0067] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.
[0068] For the existing solution, in the process of establishing Iur synchronous bearer in SRNC, because it does not know which RNCs in the network are DRNCs in the same service area as itself, it is impossible to send Iur only to DRNCs in the same service area as itself according to its own needs Synchronous bearer set-up request, thus the link resource waste problem that causes, proposes a kind of new method that realizes the synchronization among RNCs in the present invention, initiates the Iur synchronous bearer set-up process by DRNC instead of SRNC initiatively, namely: the RNC in the service area It is configured as SRNC and DRNC, and sends a session start instruction to all RNCs in the service area; after each DRNC receives the session start inst...

The invention discloses a method for realizing synchronization between radio network controllers (RNC). One RNC in a service area is collocated to form a service radio network controller (SRNC), and other RNCs are collocated to form a destination radio network controller (DRNC) except for the SRNC in the service area; a conservation beginning instruction is sent to all RNCs in the service area; after receiving the conservation beginning instruction, the DRNC requests and sets up an Iur synchronization load together with the SRNC; and the SRNC and the DRNC perform synchronization by utilizing the set up Iur synchronization load. The invention also discloses a system and equipment for realizing synchronization between RNCs and a method and a system for setting up a synchronous link circuit between the RNCs. The synchronization between the RNCs can be realized and link circuit resources can be better saved compared with the prior art by applying the method, the system and the equipment.
Description
technical field [0001] The present invention relates to mobile communication technology, in particular to a method, system and equipment for realizing synchronization among radio network controllers (RNC, RadioNetwork Control). Background technique [0002] As a new type of multimedia service, the multimedia broadcast 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 digital communication (3G, 3rd Generation). business. The MBMS service 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 Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) systems, the conditions for usin...
