According to some embodiments of the disclosure, a method includes: selecting a first subscriber identity module from a plurality of subscriber identity modules of a user equipment; and transmitting a resume request message via the first subscriber identity module, wherein the resume request message comprises first radio access network (RAN)-based notification area (RNA) update information associated with the first subscriber identity module and second RNA update information associated with a second subscriber identity module of the plurality of subscriber identity modules. ## Claims ### Claim 1 A method, comprising: selecting a first subscriber identity module from a plurality of subscriber identity modules of a user equipment, wherein the plurality of subscriber identity modules are in an inactive state; and transmitting a resume request message via the first subscriber identity module, wherein the resume request message comprises first radio access network (RAN)-based notification area (RNA) update information associated with the first subscriber identity module and second RNA update information associated with a second subscriber identity module of the plurality of subscriber identity modules. ### Claim 2 (depends on 1) The method of claim 1, wherein the first subscriber identity module is selected based on the first subscriber identity module having the best channel quality among channel qualities associated with the plurality of subscriber identity modules. ### Claim 3 (depends on 1) The method of claim 1, wherein the second RNA update information comprises at least one of the following: a resume ID of the second subscriber identity module; an authentication token of the second subscriber identity module; a serving cell ID of the second subscriber identity module; or a resume cause associated with the second subscriber identity module. ### Claim 4 (depends on 3) The method of claim 3, wherein the serving cell ID is physical cell identifier (PCI) or evolved universal terrestrial radio access network (E-UTRAN) cell global identifier (ECGI). ### Claim 5 (depends on 3) The method of claim 3, wherein the second RNA update information further comprises one of the following: configured RNA information associated with the second subscriber identity module; or a periodical RNA update indicator associated with the second subscriber identity module. ### Claim 6 (depends on 3) The method of claim 3, wherein the resume cause indicates RNA update or periodical RNA update. ### Claim 7 (depends on 1) The method of claim 1, wherein the second RNA update information comprises at least one of the following: a resume ID of the second subscriber identity module; an authentication token of the second subscriber identity module; a periodical RNA update indicator associated with the second subscriber identity module; or a resume cause associated with the second subscriber identity module. ### Claim 8 (depends on 1) The method of claim 1, further comprising: receiving a resume response message via the first subscriber identity module, wherein the resume response message comprises second resume response information associated with the second subscriber identity module. ### Claim 9 (depends on 8) The method of claim 8, wherein the second resume response information comprises a suspend configuration for the second subscriber identity module or a connection setup indication for the second subscriber identity module. ### Claim 10 (depends on 9) The method of claim 9, wherein the suspend configuration for the second subscriber identity module comprises at least one of the following: a full length of a resume ID of the second subscriber identity module; a short length of the resume ID of the second subscriber identity module; a paging cycle associated with the second subscriber identity module; RNA information associated with the second subscriber identity module; a timer value of a periodical RNA update timer associated with the second subscriber identity module; or next hop chaining count associated with the second subscriber identity module. ### Claim 11 (depends on 10) The method of claim 10, wherein the resume ID is allocated by a serving base station of the second subscriber identity module or the last serving base station of the second subscriber identity module. ### Claim 12 An apparatus, comprising: a receiving circuitry; a transmitting circuitry; and a processor coupled to the receiving circuitry and the transmitting circuitry configured to cause the apparatus to: select a first subscriber identity module from a plurality of subscriber identity modules of the apparatus, the plurality of subscriber identity modules are in an inactive state; and transmit a resume request message via the first subscriber identity module, the resume request message comprises first radio access network RAN)-based notification area (RNA) update information associated with the first subscriber identity module and second RNA update information associated with a second subscriber identity module of the plurality of subscriber identity modules. ### Claim 13 An apparatus, comprising: a receiving circuitry; a transmitting circuitry; and a processor coupled to the receiving circuitry and the transmitting circuitry configured to cause the apparatus to receive a resume request message from a user equipment (UE), the resume request message comprising first radio access network (RAN)-based notification area (RNA) update information associated with a first subscriber identity module of the UE served by a first base station and second RNA update information associated with a second subscriber identity module of the UE. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the processor coupled to the receiving circuitry and the transmitting circuitry is configured to cause the apparatus to: transmit a RNA update indication associated with the second subscriber identity module to a second base station currently serving the second subscriber identity module; and receive a RNA update response from the second base station. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the second RNA update information comprises at least one of the following: a resume ID of the second subscriber identity module; an authentication token of the second subscriber identity module; a serving cell ID of the second subscriber identity module; or a resume cause associated with the second subscriber identity module. ### Claim 16 (depends on 15) The apparatus of claim 15, wherein the serving cell ID is a physical cell identifier (PCI) or an evolved universal terrestrial radio access network (E-UTRAN) cell global identifier (ECGI). ### Claim 17 (depends on 15) The apparatus of claim 15, wherein the RNA update indication associated with the second subscriber identity module comprises at least one of the following: the resume ID of the second subscriber identity module; the authentication token of the second subscriber identity module; or the resume cause associated with the second subscriber identity module. ### Claim 18 (depends on 15) The apparatus of claim 15, wherein the second RNA update information further comprises one of the following: configured RNA information associated with the second subscriber identity module; or a periodical RNA update indicator associated with the second subscriber identity module. ### Claim 19 (depends on 13) The apparatus of claim 13, wherein the processor coupled to the receiving circuitry and the transmitting circuitry is configured to cause the apparatus to transmit a RNA update indication associated with the second subscriber identity module to a third base station last serving the second subscriber identity module; and receive a RNA update response from the third base station. ### Claim 20 (depends on 19) The apparatus of claim 19, wherein the second RNA update information comprises at least one of the following: a resume ID of the second subscriber identity module;
