摘要： Embodiments of the inventive concept herein provide a method and User Equipment (UE) for handling PLMN selection involving Proximity Based Services (ProSe) communication. The method includes detecting one of a PLMN selection due to the ProSe communication followed by a manual Closed Subscriber Group (CSG) cell selection, and a manual CSG cell selection followed by the PLMN selection due to the ProSe communication, when the UE has stored a duplicate value of a Registered PLMN (RPLMN) and a duplicate of a PLMN selection mode. Further, the method includes preserving the stored duplicate value of the RPLMN and a stored duplicate of the PLMN selection mode.

摘要： A method of reducing delay in Circuit Switched FallBack (CSFB) in a Radio Access Technology (RAT) communications network. The method includes initiating, by a terminal, a combined attach procedure by sending an attach request message to the RAT communications network, receiving, by the terminal, an attach accept message along with Location Area Identification (LAI) information from the network in response to the attach request message, checking, by the terminal, network identifier information in a RAT information table based on the received LAI, and selecting a mobile network based on the network identifier information to trigger establishment of a circuit-switched call.

摘要： A method disclosed herein includes selecting, by the UE, a SNPN for registration, on the SNPN access mode being enabled. The method includes disabling, by the UE, the SNPN access mode, if the selected SNPN does not support at least one emergency service. The method includes enabling, by the UE, a Public Land Mobile Network (PLMN) selection mode to select a PLMN cell supporting the at least one emergency service, on the SNPN access mode being disabled. The method includes performing, by the UE, the at least one emergency service by camping on the selected PLMN cell. The method includes enabling, by the UE, the SNPN access mode for performing a SNPN selection procedure, on completion of the at least one emergency service.

摘要： Embodiments herein disclose a method for handling dual registration of user equipment (UE) in a wireless communication system. The method includes registering the UE on a fourth generation Radio Access Technology (4G RAT) and a fifth generation RAT (5G RAT). Further, the method includes determining, by the UE, an occurrence of at least one event. Further, the method includes suspending, by the UE, the registration on the 5G RAT. Further, the method includes performing, by the UE, communication using the registration on the 4G RAT.

摘要： A method for connecting to a Registered Public Land Mobile Network (RPLMN) after receiving an accept message with limited service from a user selected CSG cell, which is associated to a different PLMN than the RPLMN during manual CSG selection mode is disclosed. The method includes connecting to the RPLMN based on the availability of the user selected CSG cell in UTRAN. If the user selected CSG cell is not available in UTRAN, then the method includes connecting to the RPLMN by the UE using the stored duplicate value of the RPLMN. If the user selected CSG cell is available in UTRAN, then the method includes sending an ATTACH request to the user selected CSG cell without disabling the EUTRA capabilities. If the ATTACH request is failed, then the method includes connecting to the RPLMN using the stored duplicate value of the RPLMN.

摘要： A user equipment (UE) may ascertain an incapability of the network to process a pending uplink signal based on a registration acceptance message from the network. For instance, a registration acceptance message from the network, that may indicate the network is not capable of processing the pending uplink signal service. Accordingly, upon ascertaining the incapability of the network to process the pending uplink signal, the UE may release a connection (e.g., a N1 Non-Access Stratum (NAS) signaling connection) between the UE and the network, where the connection is based on camping of the UE at a cell corresponding to the radio access network (RAN) (e.g., the NG-RAN) of the network. Alternatively, the UE may initiate one of an implementation dependent timer and a release timer (e.g., a T3540 timer) to release the connection (e.g., to release the N1 NAS signaling connection).
