Abstract: In an example embodiment, a method of optimizing service delivery performed by a UE operating in EN-DC mode is disclosed. The method comprises detecting that a network service is ongoing at the UE using a first radio access technology (RAT), based on an application request sent by the UE to a network, wherein the first RAT is one of long-term evolution (LTE) and NR. The method further comprises detecting, during the ongoing network service being availed using the first RAT, a frequency of one or more NR network procedures being performed by the UE to be greater than a first threshold frequency. The method further comprises modifying a measurement interval associated with an NR cell measurement procedure, in response to detecting the frequency of the NR network procedures to be greater than the first threshold frequency. Furthermore, the method comprises continuing the Network Service using the first RAT.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose a wireless network and methods to maintain a MA PDU session at a NSACF entity. The method includes determining, by a SMF entity, that a PDU session is the MA PDU session based on an indication from a UE. Further, the method includes indicating, by the SMF entity, that the PDU session is the MA PDU session to the NSACF entity in response to determination. The wireless network may maintain the count accurately even though the PDU session is a MA PDU session.

Abstract: Disclosed are methods and systems for prioritizing cell selection for availing LADN services. A UE prioritizes cells for selection based on availability of LADN services in the cells. For handover, a base station of a cell, providing LADN services to the UE, prioritizes target cells that provide LADN services that are being currently availed by the UE for ensuring LADN service continuity. The base station initiates addition of secondary cells that provide additional LADN services that are intended by the UE. The UE can predict if a paging message is relevant to a LADN service and send serving requests to the serving cell or other cells to avail the LADN service. The UE detects relay UEs providing LADN services and prioritizes the relay UEs for selection based on availability of LADN services. The UE buffers data if the UE is located at an edge of a LADN service area.

Abstract: Methods and systems are provided for handling non-3rd generation partnership project (3GPP) slice registration in 3GPP networks. A protocol data unit (PDU) session is managed in a wireless communication network in which a user equipment (UE) determines the allowed PDU session which can be transferred from non-3GPP access to 3GPP access. Paging resources are managed in a wireless communication network in which an access and mobility management function (AMF) checks if the data to be sent on the PDU session of non-3GPP access is of single-network slice selection assistance information (S-NSSAI) which is in an allowed network slice selection assistance information (NSSAI) list of 3GPP access.

Abstract: A method for handling data, dangling in a new radio (NR) leg of a split bearer, by a user equipment (UE) is disclosed. The method comprises predicting occurrence of NR uplink (UL) leg switch; sending a buffer status report (BSR) pertaining to protocol data units (PDUs) in radio link control (RLC) layer and media access control (MAC) layer in the NR leg based on predicting the occurrence of NR UL leg switch; and initiating recovery of dangling PDUs in the NR leg after the occurrence of the NR UL leg switch, wherein the recovery includes sending the dangling PDUs to a long term evolution (LTE) leg of the split bearer.

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: 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: A method and system in the User Equipment (UE) for maintaining rejected network slice selection assistance information (NSSAI) for Single Network Slice Selection Assistance Information (S-NSSAI) not available due to maximum number of UEs reached per access type. The method comprises receiving a Non-Access Stratum (NAS) message including at least one of a registration accept, registration reject or CONFIGURATION UPDATE COMMAND message along with at least one of rejected Single Network Slice Selection Assistance Information (S-NSSAI(s)) information and a cause for the S-NSSAI not available due to maximum number of UEs reached from a network. Thereafter, the method includes determining by the UE an access type on which the rejected S-NSSAI(s) is applicable based on the received S-NSSAI(s) information and then maintaining a storage of the rejected NSSAI for the S-NSSAI not available due to the maximum number of the UEs reached per access type based on the determination.
