Title: METHOD AND DEVICE FOR PROCESSING VOLTE SERVICE, AND TERMINAL
Abstract:
Disclosed is a method for processing a VoLTE service, comprising: measuring the signal strength of an LTE network of a current serving cell during a VoLTE service call process; if the measurement result satisfies a measurement reporting condition, detecting whether an RRC connection with a network side currently exists; if no RRC connection with the network side currently exists, sending an RRC connection request to the network side to establish an RRC connection with the network side; and sending the measurement result to the network side by means of the RRC connection, the measurement result being used for instructing the network side to trigger an SRVCC process. Correspondingly, also disclosed are a device for processing a VoLTE service and a terminal. The embodiments of the present invention can avoid abnormal drop call while the network configuration is imperfect.
