Problems solved by technology

[0009] At present, users on the GSM network mainly return to LTE through terminal autonomous FR, network configuration FR, bridging, and reselection. After the user equipment falls back to the GSM network, if the LTE network signal becomes better, the user equipment cannot return to LTE in time. The network, causing the problem of poor user perception

Abstract

The invention discloses a switching method and device based on a voice service. The switching method based on the voice service comprises the following steps of: establishing a bearing link with an LTE network by user equipment to be accessed to the VOLTE voice service; judging whether the VOLTE voice service initiates SRVCC switching; if SRVCC switching is initiated, switching the VOLTE voice service to a GSM network, and issuing an LTE network identifier; when the user equipment is carried on the GSM network, LTE network signal measurement is carried out according to the LTE network identifier, and the GSM network is switched to the LTE network when the LTE network signal meets the user equipment residence condition, so that the user equipment can be switched back to the LTE network in time after falling back to the GSM network under the condition that the LTE network signal is recovered, the call quality of VOLTE voice service is improved, and user experience awareness is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a voice service-based switching method and device. Background technique [0002] The existing interoperability schemes for switching back from GSM network (2G network) to LTE network (4G network) are to return to LTE network after the LTE network falls back to GSM network, and wait for the service to be completed. There are mainly four ways to return to the LTE network: terminal independent FR, FR set by the network side, returning to the LTE network through 3G bridging, and returning to 4G through 2G reselection. obvious. [0003] The following are the implementation principles of the four methods: [0004] Terminal autonomous FR means that the user equipment does not rely on the network to issue information to return to the 4G network. When the occupied GSM network is in an idle state, the user equipment returns according to the last 4G network information measu...
