Abstract

The invention provides a multicast data processing method and device. The method is applied to a terminal device, and the terminal device includes an application processing module, a multicast data processing module and a receiving module; the method includes: the application processing module sends a multicast channel monitoring request message to the multicast data processing module; the multicast data processing module notifies The receiving module monitors the multicast channel indicated by the multicast channel monitoring request message; the application processing module sends the multicast data receiving request message to the multicast data processing module; the multicast data processing module acquires the group indicated by the multicast data receiving request message from the receiving module The multicast data stream is preprocessed and sent to the receiving module; the application processing module obtains the preprocessed multicast data stream from the receiving module and processes it. The multicast data processing method provided by the invention has high stability and safety.

Description

technical field [0001] The present invention relates to communication technology, in particular to a multicast data processing method and device. Background technique [0002] In the 3rd Generation Partnership Project (3rd Generation Partnership Project, 3GPP) mobile communication field, a Multimedia Broadcast Multicast Service (MBMS) is defined to solve the problem of excessive server traffic in unicast services. , The problem of heavy load. [0003] MBMS is a point-to-multipoint service that sends data from one data source to multiple terminal devices within a specific range, which can realize network resource sharing and improve network resource utilization. The terminal equipment supporting MBMS involves many functions, such as MBMS control, unicast service control, switching between unicast service and multicast service, and MBMS data processing. [0004] However, the internal structure of the terminal equipment supporting MBMS is not limited in the existing communica...
