Abstract: According to an example embodiment of the disclosure, a method for performing network slice reselection by a User Equipment (UE) is disclosed. The method comprises identifying allowed network slices within a first Network Slice Simultaneous Registration Group (NSSRG) for first applications at the UE. The method comprises receiving an initialization request from a second application at the UE. The method comprises determining one or more UE Route Selection Policy (URSP) rules for the second application. The method comprises determining whether the network slice required for the second application corresponds to one of the one or more allowed network slices within the first NSSRG. The method comprises transmitting, to a network, a second registration request for registration of the UE to a second NSSRG including the network slice required for the second application based on the URSP rules for the second application.

Abstract: Embodiments herein provide a method for managing a priority of Visited Public Land Mobile Networks (VPLMNs) of a wireless communication network. The method includes receiving a registration accept message including steering of roaming (SoR) information from a VPLMN; in response to a security check of the SoR information being failed, adding the VPLMN to a SoR abort list including PLMNs where a registration was aborted due to SoR; and deleting the SoR abort list after a predetermined time period.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a mobile communication system is provided. The method comprises receiving, from an access management function (AMF) entity via a base station, a configuration update command message in case that the UE supporting a multi universal subscriber identity module (MUSIM) feature is not registered for an emergency service, and disabling the MUSIM features based on the received configuration update command message. The configuration update command message includes registration result information indicating that the UE supporting the MUSIM features is registered for the emergency service.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. For example, the disclosure relates to a method for switching a data session for an application, implemented in a user equipment with dual SIM. The method includes: determining a User Equipment (UE) Route Selection Policy (URSP) rule for a primary Subscriber Identity Module (SIM) and a secondary SIM. The method includes detecting a trigger for switching the data session of the application to the secondary SIM based on determination of the URSP rule, wherein the trigger includes one of a matching traffic descriptor, a dedicated network slice, a Quality of Service (QoS) rule and a user preference. The method includes configuring the secondary SIM for the DDS based on the trigger; and switching the data session of the application to the secondary SIM for continuing the data session.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In some implementations, a user equipment (UE) and method to manage a rejected network slice selection assistance information (NSSAI) is disclosed. The method may include receiving, from a network, an activate default EPS bearer context request message with a Single-NSSAI (S-NSSAI) and a Public Land Mobile Network (PLMN) identifier (ID). In addition, the method may include removing the S-NSSAI from a rejected NSSAI list for a current PLMN.

Abstract: Methods and systems for managing AMF re-allocation is provided. The method for managing AMF reallocation during UE registration procedure with a 5G network comprises: determining if the first AMF may send a routing assistance information to the UE, on the first AMF determining that the first AMF is not a right AMF to serve the UE; sending a routing assistance information, to the UE, as response to a first registration request message; receiving routing assistance information from the first AMF; sending a second registration request message to a 5G RAN of the 5G network comprising a portion of content included in the routing assistance information; and routing the second registration request message to a second AMF of the 5G network, wherein the second AMF is determined by the 5G RAN based on the portion of content included in the routing assistance information.
