System, apparatus and method for switching network of mobile multimedia business

Abstract

The example of the invention relates to a method, a device and a system for switching networks of mobile multimedia services, wherein the method comprises: concurrently receiving the medium stream data of a second network when the signal intensity of medium stream data of a first network is detected to be smaller than the first presupposed value, decoding the medium stream data of the second network which is buffered after the medium stream data of the second network is buffered, and playing the medium stream data of the second network which is buffered, wherein the device comprises a first communication module, a detection module, a switching module, a second communication module, a processing module and a playing module. The system comprises the first network, the second network and a mobile terminal. The example of the invention realizes that time delay in a switching process is reduced in a process that a service network is switched and avoids service interruptions due to network switches when the mobile terminal carries out multimedia services.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a network switching method, device and system for mobile multimedia services. Background technique [0002] The so-called mobile multimedia service (mobile phone TV service) is to use mobile terminals to provide users with video information services. There are two ways to achieve it: one is to provide mobile terminals with broadcast and unicast TV programs and information services through the mobile communication network, and the other is to provide mobile terminals with video information services. One is to provide broadcast TV programs and information services to mobile terminals through terrestrial broadcast or satellite. [0003] The bearer network of mobile multimedia services may include mobile communication network, terrestrial digital broadcasting network, satellite broadcasting communication network, etc. The technologies carried by the mobile communication network i...

AI Technical Summary

Problems solved by technology

[0006] During the switching process of the service network, there is a certain delay between receiving the media stream data and being able to play the above media stream data, which will cause certain interruptions in the playback of the mobile terminal;

[0007] If the mobile terminal switches from the terrestrial digital broadcasting network to the mobile communication network, there will also be a certain delay in establishing the interactive connection of the Real Time Streaming Protocol (RTSP) between the mobile terminal and the streaming media server through the mobile communication network, which will cause The playback of the mobile terminal is interrupted to a certain extent
