Method and apparatus for service processing in dual card terminal device

A chip or system-on-chip, wherein the chip or 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:

• receiving, a data service request when the chip or system-on-chip performs a voice service based on the long term evolution (LTE) network, wherein the data service request is implemented based on a standalone (SA) network, and the chip or system-on-chip is in an idle state in the SA network;
• searching, in response to the data service request, for a cell corresponding to a first frequency;
• wherein the cell corresponding to the first frequency comprises a cell accessed by the chip or system-on-chip before entering the idle state;
• determining, when the chip or system-on-chip has not found the cell corresponding to the first frequency, a second frequency connected for performing the voice service based on the LTE network;
• determining, a third frequency that matches the second frequency in a first frequency combination, wherein the first frequency combination comprises a frequency connected for performing a data service of a first card and a frequency connected for performing the voice service of a second card;
• and
• performing, the data service based on the SA network when the chip or system-on-chip has found a cell corresponding to the third frequency.

A terminal device, wherein the terminal device supports communication in a standalone (SA) network, and supports communication in a long term evolution (LTE) network,

• wherein the terminal device is configured to implement:
• receiving, a data service request when the terminal device performs a voice service based on the LTE network, wherein the data service request is implemented based on the SA network, and the terminal device is in an idle state in the SA network;
• searching, in response to the data service request, for a cell corresponding to a first frequency;
• wherein the cell corresponding to the first frequency comprises a cell accessed by the terminal device before entering the idle state;
• determining, when the terminal device has not found the cell corresponding to the first frequency, a second frequency connected for performing the voice service based on the LTE network;
• determining, a third frequency that matches the second frequency in a first frequency combination, wherein the first frequency combination comprises a frequency connected for performing a data service based the SA network and a frequency connected for performing the voice service based on the LTE network;
• and
• performing, the data service based on the SA network when the terminal device has found a cell corresponding to the third frequency.
