Abstract: The disclosure discloses a system and a method implemented in the UE to perform PLMN selection using a locally stored slice aware steering of roaming (SoR) list. According to an embodiment the UE prioritizes the PLMN based on the locally stored SoR list. The UE further maintains an updated enhanced slice aware SoR information list having an updated network slice support information along with granularity information per tracking area identity of each PLMN in a database of the UE. In an embodiment, the UE updates the SoR information list in its database based on a response that is received upon sending a registration request from the PLMN.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein relate to wireless communication networks, and more particularly to managing PDU sessions in wireless communication networks. The method maintains by a user equipment (UE), a count value for the maximum number of PDU sessions for a first access and a second access on a first network entity (NE). The UE sends a PDU session establishment request when a number of active PDU sessions is lower than the count value for the maximum number of PDU sessions or an established PDU session is released on one or more of the first access and the second access in which the maximum number of the PDU sessions has been reached.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate and to a method to handle rejected NSSAI area. The method includes receiving a NAS message indicating registration accept or registration reject with a reject cause. The reject cause indicating a S-NSSAI is not available in a subset of a current registration area where the reject cause is applied for a S-NSSAI. In an example, the method includes storing the rejected S-NSSAI in a rejected NSSAI for the subset of the current registration area. In another example, the method includes deleting a current registration area based on the subset of the current registration area where the reject cause is applied for the S-NSSAI. The UE considers a S-NSSAI part of the requested NSSAI as not applicable to current tracking area and S-NSSAI part of the requested NSSAI is allowed outside current tracking area.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system. Embodiments herein disclose methods for maintaining priority of a VPLMN during a PLMN selection procedure by a UE. The method includes ignoring a pre-configured priority for a VPLMN and considering the VPLMN as a lowest priority in response to determining that the UE has entered a state and the second SOR information is not received before the UE enters the state or the received second SOR information security check is not successful. The method includes considering a priority of the VPLMN as the pre-configured priority by not considering the VPLMN as a lowest priority and stopping the timer associated with the “first SOR security check not successful” in response to determining that the UE receives the second SOR information and a second SOR security check is successful before the UE enters the state.

Abstract: A method of beam-based communication amongst a plurality of network nodes comprises detecting, by a subject node, a presence of a first set of nodes for beam-based communication, and receiving a list of a second set of nodes from at least a first node of the first set of nodes. Further, the method includes identifying at least a second node in the second set of nodes that is not detectable for beam-based communication by the subject node. The method comprises generating a distance-based mapping including distance information relating to the first set of nodes and the second node, from the subject node. Further, the method comprises transmitting, via beam-based communication by the subject node, content to a destination node based on a communication path determined using the distance-based mapping, the destination node being a node of one of the first set of nodes and the at least second node.

Abstract: A method for performing mobility-measurements in new radio (NR) based 3GPP mobile communication network is provided. The method includes receiving network information with respect to a geographical area from one or more user equipments (UEs) operating in geographical area for a predefined duration of time. The received network information is classified at various time-instants during the predefined duration of time as at least one of an NR spectrum availability and NR spectrum non-availability. An overall probability of availability of the NR spectrum within the area is calculated for a time-instant subsequent to the predefined duration of time based on the classified network information. The UE is enabled for scheduling NR measurements within the area based on the calculated probability.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for handling timer expiry during an ongoing non-access stratum (NAS) procedure in a wireless network by a UE. The method includes detecting that a last running first timer is stopped or expired. Further, the method includes performing a deregistration procedure by sending a deregistration request message to a network entity in the wireless network when the last running first timer is stopped or expired. Further, the method includes starting a second timer. Further, the method includes determining that the deregistration procedure is not successful in first attempt. Further, the method includes aborting the ongoing deregistration procedure upon determining that the deregistration procedure is not successful in the first attempt. The method can be used to ensure that the UE registers over higher priority PLMN without any delay and extra signalling.

Abstract: A user equipment (UE) and a method to maintain service session continuity in a wireless communication network are provided. The UE includes a transceiver, memory storing one or more computer programs, and one or more processors communicatively coupled to the transceiver and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the UE to identify an application running on the UE and a corresponding packet data unit (PDU) session mapping for the application data route, defer a re-evaluation of UE route selection policy (URSP), until at least one condition has been met, based on an application type, and trigger the re-evaluation and applying highest priority URSP rules for traffic for the identified application during an ongoing service session based on the application type.

Abstract: According to various embodiments, a method performed by a user equipment (UE) in a wireless network may include receiving a steering of roaming connected mode control information (SOR-CMCI) configuration or SOR information from a network entity, initiating a timer in response to receiving the SOR-CMCI configuration or the SOR information from the network entity, identifying whether the UE is in an idle mode before expiry of the timer, in case that the UE is in the idle mode, identifying a condition under which the UE is in the idle mode, and performing, based on the condition, a first operation of allowing the timer to continue running, or a second operation of stopping the timer and selecting a public land mobile network (PLMN).
