Abstract

A cell reselection method including: carrying out a cell reselection process on a target SIM card among at least two SIM cards so as to obtain a cell reselection result for the target SIM card; and reusing the cell reselection result of the target SIM card for the other SIM card(s) among the at least two SIM cards.

Claims (50)

1. A method for cell reselection, applied to a mobile terminal provided with at least two subscriber identity module (SIM) cards, and comprising:

determining, when there is a SIM card in a connected state among the at least two SIM cards, the SIM card in the connected state as a target SIM card;

carrying out a cell reselection process on the target SIM card among the at least two SIM cards to obtain a cell reselection result of the target SIM card; and

reusing the cell reselection result of the target SIM card for another SIM card(s) among the at least two SIM cards;

wherein reusing the cell reselection result of the target SIM card for the another SIM card(s) among the at least two SIM cards comprises:

determining, when the SIM card in the connected state is not a main SIM card and the main SIM card is in an idle state or an inactive state, a reselected target cell in a cell reselection result of the SIM card in the connected state as a resident cell of the main SIM card.

2. The method according to claim 1 , wherein reusing the cell reselection result of the target SIM card for the another SIM card(s) among the at least two SIM cards further comprises:

determining the reselected target cell in the cell reselection result of the target SIM card as a resident cell of SIM card(s) other than the main SIM card among the at least two SIM cards.

3. The method according to claim 1 , wherein the at least two SIM cards belong to a same operator network.

4. The method according to claim 1 , further comprising:

determining, when the at least two SIM cards are in the idle state or the inactive state, the main SIM card among the at least two SIM cards as the target SIM card, wherein

the main SIM card is defaulted; or

the main SIM card is designated by a core network; or

the main SIM card is designated by an access network; or

the main SIM card is designated by a user.

5. The method according to claim 1 , wherein:

the cell reselection result carried out by the target SIM card includes identification of a reselected target cell; and

determining the reselected target cell in the cell reselection result of the SIM card in the connected state as the resident cell of the main SIM card comprises:

determining the reselected target cell in the cell reselection result of the SIM card in the connected state as the resident cell of the main SIM card without conducting a cell reselection process.

6. A mobile terminal, internally provided with at least two subscriber identity module (SIM) cards, and comprising:

a processor; and

a transceiver connected with the processor, wherein

the processor is configured to load and execute executable instructions to:

determine, when there is a SIM card in a connected state among the at least two SIM cards, the SIM card in the connected state as a target SIM card;

carry out a cell reselection process on the target SIM card among the at least two SIM cards to obtain a cell reselection result of the target SIM card; and

reuse the cell reselection result of the target SIM card for another SIM card(s) among the at least two SIM cards;

wherein the processor is further configured to load and execute executable instructions to:

determine, when the SIM card in the connected state is not a main SIM card and the main SIM card is in an idle state or an inactive state, a reselected target cell in a cell reselection result of the SIM card in the connected state as a resident cell of the main SIM card.

7. The mobile terminal according to claim 6 , wherein the processor is further configured to load and execute executable instructions to:

determine the reselected target cell in the cell reselection result of the target SIM card as a resident cell of SIM card(s) other than the main SIM card among the at least two SIM cards.

8. The mobile terminal according to claim 6 , wherein the at least two SIM cards belong to a same operator network.

9. The mobile terminal according to claim 6 , wherein the processor is further configured to load and execute executable instructions to determine, when the at least two SIM cards are in the idle state or the inactive state, the main SIM card among the at least two SIM cards as the target SIM card, wherein:

the main SIM card is defaulted; or

the main SIM card is designated by a core network; or

the main SIM card is designated by an access network; or

the main SIM card is designated by a user.

10. A non-transitory computer-readable storage medium, storing at least one instruction, at least one program, a code set, or an instruction set, wherein the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by a processor to:

determine, when there is a SIM card in a connected state among the at least two SIM cards, the SIM card in the connected state as a target SIM card;

carry out a cell reselection process on the target SIM card among the at least two SIM cards to obtain a cell reselection result of the target SIM card; and

reuse the cell reselection result of the target SIM card for another SIM card(s) among the at least two SIM cards;

wherein the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to:

determine, when the SIM card in the connected state is not a main SIM card and the main SIM card is in an idle state or an inactive state, a reselected target cell in a cell reselection result of the SIM card in the connected state as a resident cell of the main SIM card.

11. The non-transitory computer-readable storage medium according to claim 10 , wherein the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to:

determine the reselected target cell in the cell reselection result of the target SIM card as a resident cell of SIM card(s) other than the main SIM card among the at least two SIM cards.

12. The non-transitory computer-readable storage medium according to claim 10 , wherein a at least two SIM cards belong to the same operator network.

13. The non-transitory computer-readable storage medium according to claim 10 , wherein the at least one instruction, the at least one program, the code set or the instruction set is loaded and executed by the processor to determine, when the at least two SIM cards are in the idle state or the inactive state, the main SIM card among the at least two SIM cards as the target SIM card, wherein:

the main SIM card is defaulted; or

the main SIM card is designated by a core network; or

the main SIM card is designated by an access network; or

the main SIM card is designated by a user.
