Method and apparatus for service processing in dual card terminal device

A method for service processing in a dual card terminal device, wherein the terminal device supports communication through a first network corresponding to a first subscriber identity module (SIM) card and supports communication through a second network corresponding to a second SIM card, the method comprising:

• receiving, by the terminal device when the terminal device is using a second band of the second network for performing a voice service and the terminal device is in an idle state on the first network, a data service request;
• searching, by the terminal device in response to the data service request, for a first cell corresponding to a first band, wherein the first cell is a cell accessed by the terminal device before entering the idle state in the first network;
• and
• implementing, by the terminal device based on the terminal device finding the first cell, the data service of the first SIM card on the first network.

An apparatus for service processing, the apparatus comprising:

• a processor;
• and
• a memory, wherein the memory is configured to store code instructions, the apparatus supports communication through a first network corresponding to a first subscriber identity module (SIM) card and supports communication through a second network corresponding to a second SIM card, wherein the processor is configured to execute the code instructions to implement operations comprising:
• receiving, by the apparatus when the apparatus is using a second band of the second network for performing a voice service and the apparatus is in an idle state on the first network, a data service request;
• searching, by the apparatus in response to the data service request, for a first cell corresponding to a first band, wherein the first cell is a cell accessed by the apparatus before entering the idle state in the first network;
• and
• implementing, by the apparatus based on the apparatus finding the first cell, the data service of the first SIM card on the first network.

A chip or a system-on-chip, wherein the chip or the system-on-chip supports communication through a first network corresponding to a first subscriber identity module (SIM) card and supports communication through a second network corresponding to a second SIM card, wherein the chip or the system-on-chip includes at least one processor and a communication interface, the at least one processor is configured to run computer programs or instructions to implement operations comprising:

• receiving, by the chip or the system-on-chip when the chip or the system-on-chip is using a second band of the second network for performing a voice service and the chip or the system-on-chip is in an idle state on the first network, a data service request;
• searching, by the chip or the system-on-chip in response to the data service request, for a first cell corresponding to a first band, wherein the first cell is a cell accessed by the chip or the system-on-chip before entering the idle state in the first network;
• and
• implementing, by the chip or the system-on-chip based on the chip or the system-on-chip finding the first cell, the data service of the first SIM card on the first network.
