A method for a user equipment (UE) for performing a paging reception is provided. The method includes determining whether the UE registers to a first network associated with an Evolved Packet Core (EPC) network; determining whether to transmit a requested offset value for a paging occasion calculation to the first network after the UE determines that the UE registers to the first network; transmitting, to the first network, the requested offset value after the UE determines to transmit the requested offset value to the first network; receiving, from the first network, a configured offset value for the paging occasion calculation; forwarding, by a Non-Access-Stratum (NAS) layer of the UE, to a lower layer of the UE, the configured offset value; and performing the paging reception based on a first UE identity (ID), wherein the first UE ID is determined based on the configured offset value.

Systems, methods, apparatuses, and computer program products for user equipment (UE) context duplication. In certain embodiments, when a UE may resume at a target network node within its configured radio area, a duplication of a UE context may occur at the target network node, and the target network node may allocate an additional/secondary identifier to the UE. The secondary identifier may indicate the UE's identity within the network. When configured with a secondary identifier, the UE may retain an original/primary identifier assigned by the anchor network node. The anchor network node may retain the UE context and may maintain user plane connectivity to a core network. The UE may use this primary identifier for operations within the configured radio area, whereas the secondary identifier may be used when resuming operations to a cell that is outside of the configured radio area.

Disclosed are a method for transmitting paging in a wireless communication system, and an apparatus therefor. Particularly, a method for transmitting, by a base station (eNB), paging in a wireless communication system comprises the steps of: receiving, from a mobility management entity (MME), a paging message including settings for retransmission of paging information by the base station; and transmitting the paging information to a terminal via a paging control channel (PCCH), wherein the paging information may be transmitted to the terminal by the base station a predetermined number of times.

A method for sending a paging message is performed by a first base station connected to a first SIM in a terminal, which sends to a target base station a paging message for paging a second SIM in a radio resource control (RRC) inactive state within a terminal. The target base station is a second base station adjacent to the first base station, or the target base station includes a second base station and a base station adjacent to the second base station.

A method for optimizing cell selection in a Dual Subscriber Identification Module (SIM) Dual Standby (DSDS) device is provided. The method includes selecting at least one candidate neighbor cell for a first SIM from a mapping table of the DSDS device, the at least one selected candidate neighbor cell corresponding to a cell currently serving a second SIM, wherein the first SIM is out of service and the second SIM is in service, and camping the first SIM onto the at least one selected candidate neighbor cell.

An apparatus and a method for providing a Long Term Evolution (LTE) service in an electronic device are provided. A method for operating an electronic device includes connecting to a first network, when being connected to the first network, receiving incoming call information of a second network, obtaining caller identification information of the incoming call information of the second network, and determining whether to connect a call based on the caller identification information.

Method, device, and chip for allocating radio frequency (RF) resources by a multi-subscriber identification module (SIM) including at least a first SIM and a second SIM. The method includes determining a frequency of RF resource allocation to the second SIM based on at least one of a data communication state of the first SIM in a connected mode and a received signal state of the second SIM in an idle state, and allocating the RF resources to the second SIM based on the frequency of the RF resource allocation.

The present specification provides a method for processing, by an access and mobility management function (AMF) device in a first network, a request from a user equipment (UE). The method may comprise receiving, by the AMF device in the first network, a first request message from the UE that supports multiple universal subscriber identity modules (USIMs) and has received a paging message from a second network. The first request message may comprise information on one or more protocol data unit (PDU) sessions and information on release. The method may comprise transmitting a second message to a session management function (SMF) device in the first network. The second message may comprise information on the one or more PDU sessions based on the first request message. The method may comprise performing a procedure for releasing with a radio access network (RAN) in the first network.

A user equipment and a method for a multi-Subscriber Identity Module (multi-SIM) operation are provided. The method includes registering to a first network associated with a first Subscriber Identity Module (SIM) and a second network associated with a second SIM; determining whether a paging collision associated with the first network and the second network is detected; and initiating a paging collision resolution procedure associated with a selected network to resolve the paging collision after the paging collision is detected, where the selected network is the first network or the second network.
