INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A method for multiple-card (multi-card) terminal device cooperative communication is applicable to a terminal device. The terminal device includes a first SIM-card set and a second SIM-card set, and at least one first SIM card in the first SIM-card set and at least one second SIM card in the second SIM-card set have a capability related to cooperative paging and/or cooperative operation. The method includes the following. The at least one first SIM card in the first SIM-card set transmits to the at least one second SIM-card in the second SIM-card set paging-related data corresponding to the at least one second SIM-card in the second SIM-card set in response to reception of the paging-related data. ## Claims ### Claim 1 A method for multiple-card (multi-card) terminal device communication, performed by a terminal device, the terminal device comprising a first subscriber identity module (SIM)-card set and a second SIM-card set, at least one first SIM-card in the first SIM-card set and at least one second SIM-card in the second SIM-card set having a capability related to cooperative paging and/or cooperative operation, the method comprising: transmitting, by the at least one first SIM-card in the first SIM-card set to the at least one second SIM-card in the second SIM-card set, paging-related data corresponding to the at least one second SIM-card in the second SIM-card set in response to reception of the paging-related data; wherein the method further comprises: receiving, by the terminal device, first indication information transmitted by an access network device or a core network device, wherein the first indication information indicates whether the terminal device is allowed to perform a function of cooperative paging and/or cooperative operation; and/or determining, by the terminal device, whether the function of cooperative paging and/or cooperative operation is supported, according to capability information of the terminal device. ### Claim 2 (depends on 1) The method of claim 1, further comprising: determining the first SIM-card set and the second SIM-card set according to configuration information received. ### Claim 3 (depends on 2) The method of claim 2, wherein the configuration information comprises at least one of: first configuration information obtained from the access network device; or second configuration information obtained from the core network device. ### Claim 4 (depends on 3) The method of claim 3, wherein the first configuration information comprises at least one of: identification information corresponding to an SIM card in the first SIM-card set; an inactive-radio network temporary identifier (I-RNTI) or a cell-radio network temporary identifier (C-RNTI) corresponding to an SIM card in the first SIM-card set; identification information corresponding to an SIM card in the second SIM-card set; or an I-RNTI or a C-RNTI corresponding to an SIM card in the second SIM-card set. ### Claim 5 (depends on 3) The method of claim 3, wherein the second configuration information comprises at least one of: identification information corresponding to an SIM card in the first SIM-card set; a service-temporary mobile subscriber identifier (S-TMSI) corresponding to an SIM card in the first SIM-card set; identification information corresponding to an SIM card in the second SIM-card set; or an S-TMSI corresponding to an SIM card in the second SIM-card set. ### Claim 6 (depends on 1) The method of claim 1, wherein the paging-related data comprises: an S-TMSI allocated by the core network device; or an I-RNTI allocated by the access network device. ### Claim 7 (depends on 6) The method of claim 6, wherein the paging-related data further comprises at least one of: non-3rd generation partnership project (3GPP) paging indication information; or paging cause information associated with the S-TMSI or the I-RNTI. ### Claim 8 (depends on 1) The method of claim 1, further comprising: receiving, by the at least one first SIM-card in the first SIM-card set, indication information indicative of system information update and/or indication information indicative of alarm information for the at least one second SIM-card in the second SIM-card set, and transmitting, by the at least one first SIM-card in the first SIM-card set, the indication information indicative of system information update and/or the indication information indicative of alarm information to the at least one second SIM-card in the second SIM-card set. ### Claim 9 (depends on 1) An electronic device, comprising: a processor, a memory, a transceiver, and one or more programs stored in the memory; wherein when the one or more programs are executed by the processor, the electronic device is caused to perform the method of claim 1. ### Claim 10 A method for multiple-card (multi-card) terminal device cooperative communication, comprising: determining, by an access network device, a first subscriber identity module (SIM)-card set and a second SIM-card set that correspond to a terminal device, at least one first SIM-card in the first SIM-card set and at least one second SIM-card in the second SIM-card set having a capability related to cooperative paging and/or cooperative operation; and transmitting, by the access network device, first signaling or first communication information to the at least one first SIM-card in the first SIM-card set, the first signaling or the first communication information comprising paging-related data corresponding to the at least one second SIM-card in the second SIM-card set; wherein the method further comprises: transmitting, by the access network device, first indication information to the terminal device, wherein the first indication information indicates whether the terminal device is allowed to perform a function of cooperative paging and/or cooperative operation. ### Claim 11 (depends on 10) The method of claim 10, further comprising: transmitting, by the access network device, first configuration information to the terminal device, wherein the first configuration information is used for the terminal device to determine the first SIM-card set and the second SIM-card set. ### Claim 12 (depends on 11) The method of claim 11, wherein the first configuration information comprises at least one of: identification information corresponding to an SIM card in the first SIM-card set; an inactive-radio network temporary identifier (I-RNTI) or a cell-radio network temporary identifier (C-RNTI) corresponding to an SIM card in the first SIM-card set; identification information corresponding to an SIM card in the second SIM-card set; or an I-RNTI or a C-RNTI corresponding to an SIM card in the second SIM-card set. ### Claim 13 (depends on 10) The method of claim 10, wherein the paging-related data comprises: an I-RNTI allocated by the access network device; or a service-temporary mobile subscriber identifier (S-TMSI) allocated by a core network device. ### Claim 14 (depends on 13) The method of claim 13, wherein the paging-related data further comprises at least one of: non-3rd generation partnership project (3GPP) paging indication information; or paging cause information associated with the S-TMSI or the I-RNTI. ### Claim 15 (depends on 10) The method of claim 10, further comprising: transmitting, by the access network device, indication information indicative of system information update and/or indication information indicative of alarm information for the at least one second SIM-card in the second SIM-card set to the at least one first SIM-card in the first SIM-card set. ### Claim 16 (depends on 10) An access network device, comprising: a processor, a memory, a transceiver, and one or more programs stored in the memory; wherein when the one or more programs are executed by the processor, the access network device is caused to perform the method of claim 10.
