Problems solved by technology

[0003] Traditionally, after the user equipment switches from LTE to UMTS, both voice and video are switched to the circuit domain (64k). In this way, the voice service and video service will compete with each other for bandwidth, and the video service is of very poor quality because the bandwidth is limited to 64k , so that the quality of the video service cannot be guaranteed or even used, and the user experience is very bad

[0096] Among them, the v'SRVCC is transmitted from the MME to the MSC Server through the Sv interface, and the MSC Server does not perform any special processing, and transmits it transparently to the SBC. Specifically, it may include: carrying the v'SRVCC identifier in the Sv interface (the interface between the MME and the MSC Server), Then, during the session transfer process, the MSC Server transmits the SIP Invite message to the ICSCF-SCC AS. After the SBC obtains the C-MSISDN, it parses out that it is a video call switch and does not turn off the video.

[0097] In order to better implement the handover control method provided by the embodiment of the present invention, the embodiment of the present invention further provides a device based on the above handover control method. The meanings of the nouns are the same as those in the above handover control method, and for specific implementation details, refer to ...

Abstract

The embodiment of the invention discloses a switching control method, a system and a related device. The method of the embodiment comprises steps: when user equipment is switched to a target network cell from a source network cell, a voice bearer is switched to a circuit domain, a video bearer is switched to a grouping domain, a video continuity identifier is carried in a switching request message, the voice bearer is switched to the circuit domain and the video is switched to the PS domain for keeping flowing of a video flow, quality of the voice service and the video service can be well ensured, and user experience is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a switching control method, system and related devices. Background technique [0002] In the wireless communication system, the Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System) has been widely used, and the Long Term Evolution (LTE, Long Term Evolution) technology is also gradually used. The user equipment has weak LTE signal coverage and strong UMTS signal coverage. In some cases, it can be switched to UMTS for service transmission. [0003] Traditionally, after the user equipment switches from LTE to UMTS, both voice and video are switched to the circuit domain (64k). In this way, the voice service and video service will compete with each other for bandwidth, and the video service is of very poor quality because the bandwidth is limited to 64k , so that the quality of the video service cannot be guaranteed, or even cannot be used, ...
