Method and Terminal for Supporting Voice Service and Data Service Simultaneously

A dual subscriber identity module (SIM), dual-standby, single-pass terminal configured to support a primary card and a secondary card, wherein the dual SIM, dual-standby, single-pass terminal comprises:

• a first modem coupled to the primary card and configured to support a data service;
• a second modem coupled to the secondary card and configured to support a target service, wherein the target service is a voice service over packet switched (PS) domain;
• a display screen;
• and
• a processor coupled to the first modem, the second modem, and the display screen and configured to:
• display a first option interface on the display screen, wherein the first option interface comprises a switch, wherein the switch is configured to set whether a first function is enabled, and wherein the first function is switching the data service from the primary card to the secondary card when the secondary card performs the target service;
• enable, in response to an operation on the switch, the first function;
• perform a first data service using the first modem coupled to the primary card;
• in response to performing the target service using the second modem and the first function being enabled, switch the first data service to the second modem and perform the first data service and the target service using the second modem;
• and
• in response to performing another voice service using the secondary card and the first function being enabled, not switch the first data service to the secondary card.

A method implemented by a dual subscriber identity module (SIM), dual-standby, single-pass terminal, wherein the dual SIM, dual-standby, single-pass terminal supports a primary card and a secondary card, wherein the primary card supports a data service, wherein the secondary card supports a target service, wherein the target service is a voice service over packet switched (PS) domain, and wherein the method comprises:

• displaying a first option interface comprising a switch, wherein the switch is configured to set whether a first function is enabled, and wherein the first function is switching the data service from the primary card to the secondary card when the secondary card performs the target service;
• enabling, in response to an operation on the switch, the first function;
• when a first data service is launched during execution of the target service using the secondary card and the first function is enabled, performing the first data service using the secondary card by default instead of the primary card according to the first function;
• and
• when a second data service is launched during execution of another voice service using the secondary card and the first function is enabled, perform the second data service using the primary card by default.
