Abstract

The invention discloses a synchronizing method of multimedia broadcast and multicast service data between radio network controllers, which is used for realizing the synchronization of multimedia broadcast and multicast service data between a master radio network controller and at least one slave radio network controller and comprises the following steps: the master radio network controller configures a transmission delay of multimedia broadcast and multicast service data packages from the master radio network controller to the slave radio network controller; the master radio network controller determines a timestamp for the multimedia broadcast and multicast service data packages according to the configured transmission delay and a present time at which the master radio network controllerbegins to process the multimedia broadcast and multicast service data packages, and leads the multimedia broadcast and multicast service data packages to carry the timestamp; and the master radio network controller sends the multimedia broadcast and multicast service data packages that carry the timestamp to the slave radio network controller. The invention further discloses a synchronizing device of multimedia broadcast and multicast service data between radio network controllers.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for synchronizing Multimedia Broadcast / Multicast Service (MBMS) data between Radio Network Controllers (RNC for short). Background technique [0002] With the rapid development of the Internet network, people's demand for mobile communication is no longer only satisfied with telephone and message services. At present, a large number of multimedia services have appeared. For some of the application services, multiple users can receive the same data at the same time, such as video on demand, TV broadcast, video conferencing, online education, interactive games, etc. [0003] In order to realize the most effective use of mobile network resources, MBMS technology has emerged. MBMS refers to a point-to-multipoint service in which one data source sends data to multiple users. It realizes the sharing of network resources, including the sharing...
