Problems solved by technology

The introduction of this technology brings new problems: since the signals from different base stations are regarded as multi-path by the UE, it is required that the data of each path must be sent synchronously
However, in the prior art, there is no method for inter-RNC synchronization in this case

Embodiment Construction

[0022] Referring to FIG. 1 , it illustrates a networking environment of a preferred embodiment of the inter-RNC MBMS data synchronization system provided by the present invention. As shown in the figure, a group of RNCs that need to establish the same MBMS service are formed into an RNC group, and one of the RNCs is set as the service master RNC (hereinafter referred to as main_RNC), and the other RNCs are service slave RNCs (hereinafter referred to as sub_RNC). Generally, there is one main_RNC, and there may be multiple sub_RNCs, at least one, for example, there are two in the figure (service slave RNC1 and service slave RNCn). The role setting of main_RNC and sub_RNC can be realized in two ways: RNC operation and maintenance system configuration, or through the signaling process between the core network and RNC to complete the configuration. The interface between the RNCs is an Iur interface, and the interface between the core network (CN) and the RNC is an Iu interface. Th...

Abstract

The provided synchronizing method for MBMS data among RNC comprises: forming a RNC group by all RNC for same MBMS business, setting one inside as the primary RNC, others as the slave ones; during synchronizing, the primary RNVC provides FP frame carried CFN uniformly to the slave RNC. This invention can be applies in mobile communication system.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and system for MBMS (Multimedia Broadcast / Multicast Service, multimedia broadcast / multicast service) data synchronization between RNCs (Radio Network Controllers, radio network controllers). Background technique [0002] Now people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet, a large number of multimedia services have emerged. For some of these application services, multiple users can receive the same data at the same time, such as video on demand, TV broadcasting, video conferencing, online education, and interactive games. MBMS technology is proposed to realize the most effective use of mobile network resources. It refers to a point-to-multipoint service in which one data source sends data to multiple users, and realizes network resource sharing, including mobile cor...
