Abstract: Embodiments herein provide a method for maintaining service continuity by a User Equipment (UE) in a wireless communication system. The method includes transmitting a registration request message or a tracking area update (TAU) message to a management entity of a first radio access technology (RAT) network, when the UE is registered in the first RAT network and a second RAT network; receiving, from the management entity, a registration reject message or a TAU reject message; and transmitting, to the management entity, a registration message for initial registration or an attach request message including a registration status information of the UE of the second RAT network.

Abstract: The embodiments herein achieve a method and a UE for enabling a transport layer optimization using a preemptive cross layer signaling. The method includes transmitting at least one information to the NR L2 receiver for the transport layer optimization for a data flow(s). The at least one information includes at least one of a configuration for requesting a buffer status of the NR L2 receiver, a policy to inspect data packets of the data flow(s), a configuration for enabling or disabling the transport layer optimization, a retransmission timeout (RTO) and a round trip time (RTT) of the data flow(s), an impending RTO value of the data flow(s) and a threshold value of a buffer size. Further, the method includes enabling the transport layer optimization based on the at least one information received from the NR L3 receiver to avoid receiving of duplicate data packets from a TCP sender.

Abstract: Embodiments herein achieve a method for handling registration and session management in a wireless communication system. The method includes registering, by a User Equipment (UE), with a first core network entity over a 3GPP access network and a non-3GPP access network. Further, the method includes triggering, by the UE, a registration procedure to a second core network over the 3GPP access network when a periodic timer of the UE expires in an OOS state. Further, the method includes receiving, by the UE, a non-access stratum (NAS) message, over the 3GPP access network, with an indication to register for the non-3GPP access network with the second core network entity. Further, the method includes reinitiating the registration procedure to register again for the non-3GPP access with the second core network entity through the non-3GPP access network.

Abstract: A method for handling collision of signaling messages between a user equipment (UE) and a network entity is disclosed. The method includes transmitting a first signaling message comprising a first access type and a second signaling message comprising a second access type different from the first access type. The UE is registered on a network for the first access type and the second access type. The method also includes determining that the first access type and the second access type correspond to different access types. The method further includes processing the first signaling message and the second signaling message based on the determination by processing of the first signaling message and the second signaling message in parallel or re-triggering one or more of the first signaling message or the second signaling message.

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: 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. A method of handling control plane data in a wireless network. The method comprises sending, by a user entity (UE), a non-access stratum (NAS) message along with an indication data to a mobility management (MM) core network entity. The MM core network entity processes the received NAS message and the indication data. The MM core network entity determines status of network congestion upon processing the processed NAS message. Sending, by the MM core network entity, a response to the UE based on at least one of the processed indication data and the determined network congestion.

Abstract: A method in a mobile station (MS) and an MS in a wireless communication network are provided. The method includes detecting an intersystem change from an S1 mode to one of an A/Gb mode and an Iu mode, detecting that a routing area update (RAU) has failed detecting that a successful generic location updating procedure has not been performed since the detected intersystem change, and triggering an MM specific procedure based on detecting that the RAU has failed and the successful generic location updating procedure has not been performed. The MM specific procedure corresponds to a location area update (LAU).
