[0027] In summary, it can be seen that although the existing MBMS Iur synchronization scheme can realize the synchronization between different RNCs, in the existing MBMS Iur synchronization scheme, each RNC in the service area needs to establish transmission with the service center through the core network. channel, through which the MBMS service data from the service center is received, but each DRNC will not process the MBMS service data received from the service center, and only the SRNC will process the received MBMS service data through Iur synchronous bearer is sent to each DRNC
That is to say, the transmission channels established between each DRNC and the service center are essentially useless, thus causing a waste of these bearer resources

Embodiment Construction
[0054] 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.
[0055] Aiming at the problems existing in the prior art, a new method for realizing synchronization between RNCs is proposed in the present invention, and its corresponding network architecture is as follows Figure 5 shown. By configuring the service center and SRNC, instead of establishing a transmission channel from the service center to the DRNC as in the prior art, it is only necessary to establish a transmission channel from the service center to the SRNC, and then the SRNC will receive MBMS service data from the service center The Iur synchronous bearer established between itself and each DRNC is sent to each DRNC, thereby avoiding the waste of bearer resources.
[0056] The specific implementation of the method includes: configuring an RNC in t...

The invention discloses a method for realizing synchronization between wireless network controllers (RNC). The method comprises the following steps: an RNC in the network is configured into a service wireless network controller (SRNC), the service area information respectively corresponding to different multimedia broadcasting services (MBMS) is configured to the SRNC, and only the information ofthe SRNC is configured to a service center; the service center initiates an MBMS service and transmits a conversation starting command to the SRNC; and the SRNC establishes a transmission channel with the service center and also establishes Iur synchronous bearing with an objective wireless network controller (DRNC) corresponding to the MBMS service in the service area; and the SRNC receives the MBMS service data from the service center through the established transmission channel and performs synchronization with the DRNC in the service area corresponding to the MBMS by using the establishedIur synchronous bearing. The invention also discloses a system and a device for realizing the synchronization between the RNCs. The bearer resources can be better saved when the synchronization between the RNCs is realized by applying the method, the system and the device.
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, Radio Network 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 usi...
