Background
SRVCC (Single Radio Voice Call Continuity) is a Voice over LTE (Voice over LTE) Continuity scheme based on an IP Multimedia Subsystem (IMS) proposed by the third Generation Partnership Project (3 GPP), and mainly aims to solve the problem of guaranteeing Voice Call Continuity when a Radio User Equipment (UE) moves between a Long Term Evolution (LTE) network and a Second Generation mobile communication (Second Generation, 2G)/third Generation mobile communication (3rd Generation, 3G) Circuit Switched (CS) domain network.
Single Radio Voice Call continuity before Ringing (bSRVCC) is one of SRVCC technologies, which generally refers to that after a terminal receives a session progress message, handover occurs before a Ringing message is received, and the session progress message indicates whether a network supports bSRVCC handover or not, when the network supports bSRVCC handover, the network is handed over to a 2G/3G network through bSRVCC after receiving a handover instruction to perform a session, and if the network does not support bSRVCC handover, the network handover fails.
Since mobile VoLTE is gradually popularized, it often appears in a place with poor LTE signal, and a VoLTE call is disconnected. Because the LTE signal is too poor, the switching from the LTE network to the 2G/3G network is not completed in advance, and the call is failed.

In practical application, step 101 specifically includes: sending an update request to the network device; receiving the updating information returned by the network equipment responding to the updating request; the updating information at least comprises a first switching parameter corresponding to the current network environment where the terminal equipment is located.
Further, according to a preset time interval, regularly sending an updating request to the network equipment; or when the network environment of the terminal changes, the terminal sends an update request to the network equipment.
The processing method of voice call continuity provided in the embodiment of the present invention can be applied to single radio frequency voice call continuity SRVCC, single radio frequency voice call continuity bSRVCC before ringing, ringing state single radio frequency voice continuity (alerting SRVCC, aSRVCC), and the like.
In practical application, the first handover parameter is obtained by measuring signal quality in a network environment, so that different areas can store the first handover parameters corresponding to different network environments in the network equipment in advance according to different network environments, and when the user terminal moves to a certain area, the user terminal can update the stored second handover parameter according to the first handover parameter corresponding to the area stored in the network equipment, so that the handover decision of the user terminal is completely applicable to the current network environment of the area.
In practical application, the position information of the terminal device is sent to the network device, so that the network device determines the first switching parameter of the current network environment where the terminal device is located according to the position information of the terminal device.
That is to say, before determining the first switching parameter of the current network environment where the terminal device is located, the corresponding network environment needs to be indexed according to the location information of the terminal device, the indexed network environment is the current network environment of the area where the terminal device is located, and then the first switching parameter corresponding to the current network environment is determined.
Here, the voice call continuity handover decision includes: judging whether the signal quality of the current environment meets the updated limit of the second switching parameter, and if so, switching the VoLTE call to the gsm call; otherwise, the call is held.
In practical applications, the first switching parameter includes at least one of: a Reference Signal Received Power (RSRP) threshold, and a Signal-to-Noise Ratio (SNR) threshold.

Before determining the first switching parameter of the current network environment of the terminal equipment, the network equipment indexes the corresponding network environment according to the position information of the terminal equipment, the indexed network environment is the current network environment of the area where the terminal equipment is located, and then the first switching parameter corresponding to the current network environment is determined.
