Embodiment Construction

[0024] In the embodiment of the present invention, a kind of Multimedia Broadcast Multicast Service (MBMS) data synchronous scheduling method is provided, in this method, the clock synchronization between the radio network controllers (RNCs) is guaranteed by the GPS global positioning system, and the clock synchronization between the RNCs is carried out. The message transmission is to negotiate the sending time, and the RNC centrally controls the synchronous sending of the MBMS service in each cell according to the time after negotiation, and realizes the MBMS service Single Frequency Network (SFN) networking mode. The MBMS data synchronization scheduling method is suitable for distributed systems and centralized systems.

[0025] First of all, the network based on single frequency network (SFN) can be the whole network or regionalized SFN network. The SFN network with the same frequency can be reused in different regions (non-adjacent regions) to form another regionalized one....

Abstract

The invention provides a synchronized dispatching method for MBMS data, which comprises the steps as follows: step S102: CN sends MBMS conversation starting message to each RNC in an STN area, wherein, the MBMS conversation starting message carry identifier lists of each RNC; step S104: by responding MBMS conversation starting message, each RNC establishes wireless access loading entities and conducts RFN synchronized time negotiation through Iur port signaling; step S106: each RNC receives Iur port signaling from other RNCs, and selects the FRN with the longest synchronized delay as the starting time and the starting time is led to make response to all RNCs in the identifier lists; and the step S108: each RCN obtains the connection frame number sent out by an empty port according the starting time of the RFN.

Description

technical field [0001] The present invention relates to a data synchronization scheduling method for Multimedia Broadcast / Multicast Service (MBMS) in a wireless communication system, and more particularly, to a multimedia broadcast multicast based on single frequency network (SFN) hotspot technology Service data synchronization dispatch method. Background technique [0002] At present, people's demand for mobile communication is no longer only satisfied with telephone and message services. With the rapid development of Internet networks, 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 broadcast, 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 refers to a point-to-multipoint service in which one data source sends data ...
