Embodiment 1

[0073] Embodiments of the present invention provide a method for improving the success rate of VoLTE calls, such as image 3 As shown, the method specifically includes the following steps:

[0074] Step S301, when the mobile terminal resides on the Long Term Evolution LTE network, it receives an incoming voice call from the circuit switching CS domain on the network side;

[0075] Step S302, perform CSFB fallback processing, establish a voice call in the network that can handle CS domain voice calls, and send a message to the network side to cancel the VoLTE service after the voice call ends.

[0076] Wherein, when performing the CSFB fallback process, the current LTE network is switched to a network that can handle CS domain voice calls. Here, the network that can handle voice calls in the CS domain is any of 2G or 3G networks (GSM, WCDMA, TDSCDMA, CDMA) networks. Specifically, the switching mode is determined according to the way the mobile terminal accesses the network. ...

Embodiment 2

[0082] In the embodiment of the present invention, a method for improving the success rate of VoLTE calls is also provided. On the basis of the previous embodiment, the method for improving the success rate of VoLTE calls in this embodiment limits the specific implementation of how the mobile terminal sends a message for canceling the VoLTE service to the network side after the speech ends.

[0083] Specifically, the method for improving the success rate of VoLTE calls provided by the embodiments of the present invention, such as Figure 4 shown, including the following steps:

[0084] Step S401, when the mobile terminal resides on the Long Term Evolution LTE network and the VoLTE service registration is successful, it receives an incoming voice call from the circuit switched CS domain on the network side;

[0085] Step S402, performing circuit domain fallback CSFB processing, and establishing a voice call in a network that can handle CS domain voice calls;

[0086] Step S40...

Embodiment 3

[0094] In the embodiment of the present invention, a method for improving the success rate of VoLTE calls is also provided. On the basis of the previous embodiment, the method for improving the success rate of VoLTE calls in this embodiment is applicable to mobile terminals whose CS domain and PS domain can be processed in parallel, and the data processing speed can be effectively improved through the present invention.

[0095] Specifically, the method for improving the success rate of VoLTE calls provided by the embodiments of the present invention, such as Figure 5 shown, including the following steps:

[0096] Step S501, when the mobile terminal resides on the Long Term Evolution LTE network and the VoLTE service registration is successful, it receives an incoming voice call from the circuit switched CS domain on the network side;

[0097] Step S502, perform CSFB fallback processing, establish a voice call in the network that can handle CS domain voice calls, and send a ...

Abstract

The invention discloses a method and device for improving a VoLTE call success rate, and a storage medium. The method comprises the following steps: when a mobile terminal resides in a long term evolution LTE network, receiving a voice incoming call of a circuit switch CS domain of a network side; executing circuit domain drop CSFB processing, establishing a voice call in the network that can process the CS domain voice call, and sending a message of cancelling VoLTE service to the network side after the voice call is ended. According to the method and device, after the CSFB call is ended, if there is no voice service, the message of cancelling the VoLTE service is sent to the network side, therefore the cancellation success rate can be effectively guaranteed, and the VoLTE registration states of the terminal and the network side are consistent, thereby effectively avoiding the situation of call failure caused by the inconsistent states of the terminal during the VoLTE registration and improving the call success rate.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a method, device and storage medium for improving the success rate of VoLTE calls. Background technique [0002] VoLTE (Voice over LTE, voice long-term evolution) is an end-to-end voice solution based on the full Internet protocol on the 4G network, and it is the ultimate solution for voice in the LTE era. For operators, the deployment of VoLTE not only improves wireless spectrum utilization and reduces network costs, but also introduces services such as high-definition video telephony and high-definition voice, which significantly improves communication quality. [0003] The voice service under the 4G network is performed based on the PS (Packet Switch, packet switching) domain. However, due to reasons such as coverage and capacity in the actual network, the following phenomenon sometimes occurs: when the mobile terminal resides on the 4G network and the VoLTE regis...
