摘要： The present disclosure relates to a system and a method for connection management. The method includes establishing, by a UE, a connection with a 5G cell. The established connection with the 5G cell is in a current tracking area of a 5G New Radio (NR). Further, the method includes determining, by the UE, one or more Long-Term Evolution (LTE) cells in the current tracking area or registration area that are not accessible to the UE (300). The one or more LTE cells are configured to operate on an LTE frequency. Furthermore, the method includes temporarily deprioritising or disabling, by the UE, a Stand Alone (SA) mode based on the determination of the one or more LTE cells in the current tracking area or the registration area that are not accessible to the UE.

摘要： The present disclosure relates to an apparatus and method for cell reselection in a wireless communication system. The method comprises: determining whether a User Equipment (UE) is in an inactive mode supported by a serving cell and detecting a trigger for reselection of the serving cell for the UE, while the UE is in the inactive mode. The method further comprises identifying, based on the detection, a plurality of neighbouring cells available for being connected to the UE. The method also comprises selecting a first cell, from among the plurality of the neighbouring cells, that supports the inactive mode of the UE, for connecting with the UE.

摘要： Embodiments herein provide a method for managing a priority of Visited Public Land Mobile Networks (VPLMNs) of a wireless communication network. The method includes receiving a registration accept message including steering of roaming (SoR) information from a VPLMN; in response to a security check of the SoR information being failed, adding the VPLMN to a SoR abort list including PLMNs where a registration was aborted due to SoR; and deleting the SoR abort list after a predetermined time period.

摘要： 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.

摘要： A method of selecting access network for routing data of user equipment (UE) is provided. The method includes receiving trigger indicating a requirement of one or more network services. Further, the method includes determining that a UE is registered on a Third Generation Partnership Project (3GPP) access network and a non-3GPP access network simultaneously. The method includes identifying availability of one or more network services in the 3GPP access network and the non-3GPP access network. Thereafter, the method includes selecting one of, the 3GPP access network and the non-3GPP network, based on availability of one or more network services in one of, the 3GPP access network and the non-3GPP access network, or selecting one of, the 3GPP access network and the non-3GPP network based on one or more network parameters, when one or more network services are available in the 3GPP access network and the non-3GPP access network.

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a mobile communication system is provided. The method comprises receiving, from an access management function (AMF) entity via a base station, a configuration update command message in case that the UE supporting a multi universal subscriber identity module (MUSIM) feature is not registered for an emergency service, and disabling the MUSIM features based on the received configuration update command message. The configuration update command message includes registration result information indicating that the UE supporting the MUSIM features is registered for the emergency service.

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. In some implementations, a user equipment (UE) and method to manage a rejected network slice selection assistance information (NSSAI) is disclosed. The method may include receiving, from a network, an activate default EPS bearer context request message with a Single-NSSAI (S-NSSAI) and a Public Land Mobile Network (PLMN) identifier (ID). In addition, the method may include removing the S-NSSAI from a rejected NSSAI list for a current PLMN.

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. According to various embodiments of the present disclosure, a method of operating a user equipment (UE) in a wireless communication system is provided. The method comprises: while the UE is connected to a first cell of a new generation radio access network (NG-RAN), receiving SOR-CMCI (steering of roaming connected mode control information) from the first cell; starting a Tsor-cm timer based on the SOR-CMCI; and in case a cell change of the UE from the first cell to a second cell is detected and the second cell is a cell of an access technology other than NG-RAN; stopping the Tsor-cm timer.
