Abstract

A terminal includes a first universal subscriber identity module (USIM) and a second USIM. A method for determining a paging occasion (PO) of the terminal includes, in response to a first PO of the first USIM being the same as a PO of the second USIM, sending, by the terminal, indication information to a mobility management network element communicating with the first USIM. The indication information is used to indicate that POs of at least two USIMs in the terminal are the same. The method also includes receiving, by the terminal, a first parameter from the mobility management network element. The method further includes determining, by the terminal, a second PO of the first USIM based on the first parameter. The second PO of the first USIM is different from the PO of the second USIM.

Claims (37)

1 . A method for determining a paging occasion (PO) of a terminal, wherein the terminal comprises a first universal subscriber identity module (USIM) and a second USIM, the method is performed by a communication apparatus, wherein the communication apparatus is the terminal, or the communication apparatus is an apparatus or a chip system deployed in the terminal, and the method comprises:

only in response to a first PO of the first USIM being the same as a PO of the second USIM, sending indication information to a mobility management network element communicating with the first USIM, wherein the indication information is used to indicate that POs of at least two USIMs in the terminal are the same;

receiving a first parameter from the mobility management network element; and

determining a second PO of the first USIM based on the first parameter, wherein the second PO of the first USIM is different from the PO of the second USIM.

2 . The method according to claim 1 , wherein the method further comprises:

sending an initial parameter to the mobility management network element, wherein the initial parameter comprises a second parameter used to determine the first PO of the first USIM and a third parameter used to determine the PO of the second USIM.

3 . The method according to claim 1 , wherein before the sending the indication information to the mobility management network element communicating with the first USIM, the method further comprises:

determining that both the first USIM and the second USIM are in an idle mode.

4 . The method according to claim 1 , wherein the indication information is used to indicate that the first PO of the first USIM is the same as the PO of the second USIM.

5 . The method according to claim 1 , wherein the paging parameter comprises one or more of a short temporary mobile subscriber identity (S-TMSI) or a discontinuous reception (DRX) parameter.

6 . The method according to claim 1 , wherein the indication information comprises an initial parameter, the initial parameter comprises a globally unique temporary user equipment identity (GUTI), and the first parameter comprises a GUTI different from the GUTI in the indication information.

7 . An apparatus for determining a paging occasion (PO) of a terminal, wherein the terminal comprises a first universal subscriber identity module (USIM) and a second USIM, the apparatus comprising:

a processor; and

a computer-readable storage medium having instructions stored thereon that, when executed by the processor, cause the apparatus to:

only in response to a first PO of the first USIM being the same as a PO of the second USIM, send indication information to a mobility management network element communicating with the first USIM, wherein the indication information is used to indicate that POs of at least two USIMs in the terminal are the same;

receive a first parameter from the mobility management network element; and

determine a second PO of the first USIM based on the first parameter, wherein the second PO of the first USIM is different from the PO of the second USIM.

8 . The apparatus according to claim 7 , wherein the apparatus is further caused to:

send an initial parameter to the mobility management network element, wherein the initial parameter comprises a second parameter used to determine the first PO of the first USIM and a third parameter used to determine the PO of the second USIM.

9 . The apparatus according to claim 7 , wherein the apparatus is further caused to:

before sending the indication information to the mobility management network element communicating with the first USIM, determine that both the first USIM and the second USIM are in an idle mode.

10 . The apparatus according to claim 7 , wherein the indication information is used to indicate that the first PO of the first USIM is the same as the PO of the second USIM.

11 . The apparatus according to claim 7 , wherein the apparatus is the terminal.

12 . The apparatus according to claim 7 , wherein the apparatus is a chip included in the terminal.

13 . The apparatus according to claim 7 , wherein the paging parameter comprises one or more of a short temporary mobile subscriber identity (S-TMSI) or a discontinuous reception (DRX) parameter.

14 . The apparatus according to claim 7 , wherein the indication information comprises an initial parameter, the initial parameter comprises a globally unique temporary user equipment identity (GUTI), and the first parameter comprises a GUTI different from the GUTI in the indication information.

15 . A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by a processor, cause an apparatus to:

only in response to a first paging occasion (PO) of the first universal subscriber identity module (USIM) being the same as a PO of a second USIM, send indication information to a mobility management network element communicating with the first USIM, wherein the indication information is used to indicate that POs of at least two USIMs in a terminal are the same;

receive a first parameter from the mobility management network element; and

determine a second PO of the first USIM based on the first parameter, wherein the second PO of the first USIM is different from the PO of the second USIM.

16 . The non-transitory computer-readable storage medium according to claim 15 , wherein the apparatus is further caused to:

17 . The non-transitory computer-readable storage medium according to claim 15 , wherein before the sending the indication information to the mobility management network element communicating with the first USIM, the apparatus is further caused to:

determine that both the first USIM and the second USIM are in an idle mode.

18 . The non-transitory computer-readable storage medium according to claim 15 , wherein the indication information is used to indicate that the first PO of the first USIM is the same as the PO of the second USIM.

19 . The non-transitory computer-readable storage medium according to claim 15 , wherein the paging parameter comprises one or more of a short temporary mobile subscriber identity (S-TMSI) or a discontinuous reception (DRX) parameter.

20 . The non-transitory computer-readable storage medium according to claim 15 , wherein the indication information comprises an initial parameter, the initial parameter comprises a globally unique temporary user equipment identity (GUTI), and the first parameter comprises a GUTI different from the GUTI in the indication information.
