Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein relate to methods and systems for updating a partially allowed network slice selection assistance information (NSSAI) list, and managing a congestion timer/back-off timer for an alternative single-NSSAI (S-NSSAI) in wireless communication networks. The methods include removing network slice support information stored in a user equipment (UE), if a Non-Access Stratum (NAS) message from a network indicates to delete the network slice support information. The methods include applying a back-off timer to the S-NSSAI to be replaced (S-NSSAI-1)/alternative S-NSSAI (S-NSSAI-A)/combination of S-NSSAI-A+S-NSSAI-1, on receiving a Packet Data Unit (PDU) session establishment request, when the network is congested. The methods include applying a back-off timer to the S-NSSAI-A/S-NSSAI-1/combination of S-NSSAI-A+S-NSSAI-1, on receiving a congestion timer from the network function while requesting an alternative S-NSSAI

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein provide method for managing a Network Slice Selection Assistance Information (NSSAI) list in a wireless network by a UE. The method includes receiving at least one event. The at least one event includes: receiving a deregistration request message from a network function (NF) entity, performing a deregistration event at the UE, or successfully completing a tracking area update procedure, a successful registration procedure, or an unsuccessful registration procedure. Further, the method includes deleting: a partially rejected NSSAI list or a partially allowed NSSAI list based on the at least one received event.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and systems are provided in which control plane data is blocked for partially allowed network slice selection assistance information (NSSAI) and network slice area of service (NS-AoS) when a user equipment (UE) is in an area/cell/tracking area (TA) where the S-NSSAI is not available/supported. The UE initiates the NAS transport procedure for a cellular Internet of things (CIOT) user data container when the UE is in an area/cell/TA where the S-NSSAI is not available/supported of NS-AOS area. The UE initiates the NAS transport procedure for the CIOT user data container when the UE is in an area/cell/TA where the S-NSSAI is not available/supported of S-NSSAI supported area.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. The principal object of the embodiments herein is to disclose methods and systems for evaluating and re-evaluating a user-equipment route selection policy (URSP) rule in a wireless network. A method for re-evaluating at least one user-equipment route selection policy (URSP) rule in a wireless network, the method comprising: initiating, by a user equipment (UE), re-evaluation of the at least one USRP rule; and checking, by the UE, for a correct Route Selection Descriptor (RSD) for an application, on one of the UE moving to a tracking area (TA) where single-network slice selection assistance information (S-NSSAI) is allowed, and the UE receiving a partially allowed network slice selection assistance information (NSSAI).
