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: 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.

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.

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: 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 present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and systems for managing bearer configuration of user equipment (UE) with Evolved-Universal Terrestrial Radio Access Network-New Radio-Dual Connectivity (E-UTRAN-NR-DC) (EN-DC) capability. The UE detects connectivity issues in the UE itself and in interfaces connecting between a NR network with the UE, a LTE network, or an EPC that require disabling NR capability of the UE. The bearer configuration is determined and updated based on the detected connectivity issues. The UE signals the LTE network about the disabling of NR capability, requests enabling of data transfer through bearers of a MCG bearers associated with the LTE network in a current MCG RRC session, and prevents addition of SCG bearers associated with the NR network. The UE recovers data in the SCG bearers, lost due the issues in the NR network, through the MCG bearers. The UE can send a Tracking Area Update (TAU) to indicate the disabling of NR capability if the connectivity issues persist.
