    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.

    IPC: H04W72/04

    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: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4g) communication system such as long term evolution (LTE). Embodiments herein disclose a method for transmitting public safety warning messages over a non-3GPP access networks. The method includes receiving, by an Access and Mobility Management Function (AMF) entity of the 3GPP system (100), at least one public safety warning message from Cell Broadcast Entity (CBE) and transmitting, by the AMF entity (160a) of the 3GPP system 3GPP system (100), at least one public safety warning message to a Non-3GPP Interworking Function (N3IWF) interface entity (180a) of the 3GPP system 3GPP system (100), where the N3IWF interface entity (180a) connects the AMF entity (160a) to the non-3GPP access network. Further, the method includes transmitting, by the N3IWF interface entity (180a) of the 3GPP system 3GPP system (100), the at least one public safety warning message to at least one User Equipment (UE) over the non-3gpp access.

    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: A method and a system for optimizing acquisition time and power consumption at a user equipment (UE) are provided. The method includes establishing, by the UE located at an initial location, a radio resource control (RRC) connection with a non-terrestrial network (NTN)-based public land mobile network (PLMN), determining a current location of the UE based on one or more predetermined parameters, determining whether to perform a PLMN search for identifying a PLMN with a higher priority than connected NTN-based PLMN based at least on the initial location and the current location of the UE; and performing one of performing the PLMN search upon determining that a distance between the initial location and the current location of the UE is greater than a predetermined threshold distance value, or skipping the PLMN search upon determining that the distance between the initial location and the current location of the UE is less than the predetermined threshold distance value.
