Voice service switching method and apparatus and user equipment

User Equipment (UE), comprising:

• a first Subscriber Identification Module (SIM) card;
• a second SIM card;
• a memory storing computer-readable instructions;
• and
• a processor coupled to the memory and configured to execute the computer-readable instructions, wherein computer-readable instructions, when executed by the processor, cause the processor to perform operations comprising:
• when the second SIM card executes a first voice service, sending a first switching report message to a network side device,
• wherein the first switching report message comprises first network environment information,
• wherein the first network environment information is used to represent network quality of a mobile network corresponding to the UE when the first voice service is executed;
• receiving a first switching command message,
• wherein the first switching command message is sent by the network side device when the first network environment information meets a first target preset condition,
• wherein the first switching command message is used to instruct the UE to switch the first voice service of the second SIM card to a second voice service;
• and
• executing, according to the first switching command message, a process of switching to the second voice service,
• wherein the first voice service is at least one of the following:
• a Voice over Mobile (VoMobile) service;
• a Voice over LTE (VoLTE) service;
• or
• a Voice over Wireless Fidelity (VoWiFi) service, and
• wherein when the first voice service is the VoMobile service, the second voice service is the VoWiFi service, and when the first voice service is the VoLTE service or the VoWiFi service, the second voice service is the VoMobile service.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• when a second SIM card executes a first voice service, sending a first switching report message to a network side device,
• wherein the first switching report message comprises first network environment information,
• wherein the first network environment information is used to represent network quality of a mobile network corresponding to a User Equipment (UE) when the first voice service is executed,
• wherein the UE comprises a first Subscriber Identification Module (SIM) card and the second SIM card;
• receiving a first switching command message,
• wherein the first switching command message is sent by the network side device when the first network environment information meets a first target preset condition,
• wherein the first switching command message is used to instruct the UE to switch the first voice service of the second SIM card to a second voice service;
• and
• executing, according to the first switching command message, a process of switching to the second voice service,
• wherein the first voice service is at least one of the following:
• a Voice over Mobile (VoMobile) service;
• a Voice over LTE (VoLTE) service;
• or
• a Voice over Wireless Fidelity (VoWiFi) service, and
• wherein when the first voice service is the VoMobile service, the second voice service is the VoWiFi service, and when the first voice service is the VoLTE service or the VoWiFi service, the second voice service is the VoMobile service.
