Switching method and device of unicast service

Abstract

The invention discloses a switching method of a unicast service, comprising the following steps of: issuing the establishing process of a real-time stream transport protocol (RTSP) link to the unicast service as same as the current broadcast / multicast service on a unicast service platform by using a mobile terminal positioned in the broadcast / multicast service when the mobile terminal detects that the channel quality of the current broadcast / multicast service is lower than the first threshold value, and triggering and switching to the switching command of the unicast service after establishing the RTSP link; directly issuing the playing command of the unicast service by using the mobile terminal when receiving the switching command of the unicast service, and receiving the unicast service through the RTSP link. The invention simultaneously discloses a switching device of the unicast service. The invention can rapidly switch the broadcast / multicast service to the unicast service corresponding to the broadcast / multicast service, thereby greatly raising the experiences of users and improving the service quality provided by the whole service content.

Description

technical field [0001] The invention relates to a method and device for switching unicast services. Background technique [0002] At present, with the continuous development of mobile multimedia broadcasting services, more and more services are provided. At the same time, with the development of wireless communication technology, the wireless data access capability is also getting higher and higher. The development of microwave access global interoperability (Wimax, Worldwide Interoperability for Microwave Access), high-speed packet access (HSPA, High-Speed ​​Packet Access) and long-term evolution (LTE, Long Time Evolution) and other technologies can provide more and more wireless data access capabilities, network services are sufficient Bearer content service, the above network supports both unicast service and multicast / broadcast service. The network that provides mobile multimedia content services through broadcast / multicast is more mature. These content service systems ...

AI Technical Summary

Problems solved by technology

[0003] At present, although there is a system that integrates the broadcast / multicast service platform and the unicast service platform, the method of providing corresponding content services to users is generally still provided separately. Even if the user terminal supports both unicast and broadcast / multicast services, It is very inconvenient to switch services between unicast and broadcast / multicast, and the user experience is poor. For example, when a user is watching a broadcast / multicast live service, if the current broadcast / multicast signal is poor, the user will have to Switch to unicast mode and re-connect to the corresponding services of the unicast service platform. In this way, a long time will be wasted due to service switching, resulting in users missing important service content
