A terminal supporting dual receive single transmit-dual subscriber identity module (SIM) dual standby (DR-DSDS) includes a first SIM card interface and a second SIM card interface, and the first SIM card interface is configured to communicate with a first SIM card, and the second SIM card interface is configured to communicate with a second SIM card. The terminal is configured to, when the terminal is in a first communication connection, receive a paging request for establishing a second communication connection, and when the paging request carries a first identifier indicating a second service, respond to the paging request to establish the second communication connection.

A user device, UE, for one or more wireless communication systems, includes one or more transceiver chains. The UE shares at least one transceiver chain with at least two connections to the one or more wireless communication systems. The UE is connected to one or more network entities, like a gNB or another UE, with the connections, and perform one or more operations on the connections at respective operation occasions. When the UE transmits or receives on a current one of the connections, it does not to transmit or receive on the other connections.

The present disclosure relates to a network access method. The method includes: receiving a paging signaling of the second type network forwarded by the access node of the first type network currently accessed by the user device; accessing the second type network according to the paging signaling.

A disclosure in the present specification provides a method for user equipment initiating a service request procedure. The method includes a step of the UE receiving a paging message. The UE may be registered to both of a 3rd generation partnership project (3GPP) access and a non-3GPP access within the same PLMN. The paging message may include access type information that is used so as to indicate the non-3GPP access. The method may include a step of initiating a UE triggered service request procedure. The UE triggered service request procedure may be initiated by transmitting a service request message including a list of permitted protocol data unit (PDU) sessions. The service request message may include an empty list of the permitted PDU sessions if there is no PDU sessions that can be reactivated in the 3GPP access.

A wireless communication device (100) according to the present disclosure includes a controller (140). The controller (140) transmits a registration request message to a first management device (10A) that belongs to a first PLMN and that manages registration of a wireless communication device (100). The registration request message includes second PLMN_ID information. The second PLMN_ID information is also included in the first PLMN list information that is stored in the second subscriber identity module and that is stored in the first subscriber identity module. The controller (140) receives, from a first base station (200A) that belongs to the first PLMN, a first paging message related to a first paging that has been generated in the first PLMN. The controller (140) receives, from the first base station (200A), a second paging message related to a second paging that has been generated in a second PLMN.

The apparatus includes a processor configured to send, over a 3rd Generation Partnership project (3GPP) access, a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to the communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access. The method includes sending over a 3rd Generation Partnership project (3GPP) access a notifying message regarding non-3GPP access to a user equipment, the user equipment being simultaneously registered to a communication network via the 3GPP access and via the non-3GPP access, the user equipment being in a connection management-idle state over the non-3GPP access.

This disclosure relates to systems, apparatuses, and methods for coordinating communication and avoiding and/or mitigating collisions for multi-subscriber identity module devices in a wireless communication system. A wireless device may coordinate communication associated with different subscriber identity modules and/or may mitigate collisions between communications associated with different subscriber identity modules. A network may provide information to improve coordination and/or mitigate collisions. A network may adjust paging schedules and/or provision of alert messages to improve coordination.
