Voice switching method and device based on semi-persistent scheduling

Номер: CN115915250A
Автор: CHEN CHENYANG
Принадлежит:

The embodiment of the invention provides a voice switching method and device based on semi-persistent scheduling, which are used for enabling a current service to realize resource switching in time under the condition that a PDCCH (Physical Downlink Control Channel) is limited. The method specifically comprises the following steps: after a voice service establishes a connection, network equipment activates semi-static scheduling and issues time-frequency resources and a modulation and coding strategy; in the scheduling period of the semi-static scheduling, the network device receives a measurement report sent by a user terminal by using the time-frequency resource and the modulation and coding strategy; and the network equipment sends a switching instruction to the user terminal according to the measurement report, so that the user terminal performs voice service switching according to the switching instruction.
