Problems solved by technology

However, it is still necessary to ensure the consistency of service data and protocol control header content. The existing MBMS protocol definition uses UM mode at the RLC layer, but there is no mechanism for the fragmentation function of UM mode and the allocation of RLC sequence numbers to ensure synchronization between RNCs.
In this way, if the RLC sequence number or fragmentation is not synchronized, it will cause co-channel interference between adjacent cells, or the UE will not get receiving gain.
[0009] To sum up, in the current technical solution, there is a problem that air interface signals are not synchronized due to inconsistent serial numbers in UM mode. Therefore, a solution that can overcome the above problem and realize MBMS service synchronization between wireless network controllers is needed

Embodiment Construction

[0022] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] In an embodiment of the present invention, a method for realizing MBMS service synchronization between RNCs based on TM mode is provided; FIG. 1 is a flowchart showing the method.

[0024] With reference to Fig. 1, this method comprises: Step S102, configure the TM pattern of RNC; Step S104, the information source sends the data packet of corresponding length to radio network controller according to the transparent output mode configuration of radio network controller; And step S106, wireless network The controller processes the data packets according to the length of the data packets.

[0025] Wherein, the information source is any one of the following: a core network node and a service node.

[0026] According to different service characteristics, the RNC TM mode in step S102 can be divided into two configurations: split mode and non-split mode...

Abstract

The provided synchronizing method for MBMS business based on TM mode comprises: S102, configuring TM mode for RNC; S104, the signal source configures the data package length toward wireless network controller according to the controller transparent output mode; and S106, the latter process data package. This invention avoids asynchronous problem of idle signal.

Description

technical field [0001] The present invention relates to the field of communication, and in particular to a method for realizing service synchronization of multimedia broadcast multicast service (MBMS for short) between wireless network controllers based on a transparent mode. Background technique [0002] Now, people's demand for mobile communication is no longer only 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, for example, video on demand, TV broadcasting, video conferencing, online education, interactive games, etc. [0003] In order to realize the most effective use of mobile network resources, MBMS technology is proposed. MBMS technology is a point-to-multipoint service in which one data source sends data to multiple users, and is used to realize network resource sharing, inc...
