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.

Method and user equipment for handling dual registration in wireless communication system

A method for selecting a Public Land Mobile Network (PLMN) in a wireless communication system by a User Equipment (UE), the method includes detecting, by the UE, that the UE is operating in an interworking mode, triggering, by the UE, a manual scan in the interworking mode for acquiring a list of PLMNs in the wireless communication system, and causing, by the UE, a display to output the list of PLMNs in response to the triggering.

Selecting PLMN in wireless communication system

Methods are provided for recovering from abnormal scenarios that cause release of a connection between network and UE including, detecting an interruption of a Radio Resource (RR) connection with a first PLMN associated with at least one first parameter, the interruption resulting in a loss of access to at least one type of service from the first PLMN, adding the at least one first parameter, the at least one type of service, and a defined time period to a list for the defined time period, and detecting a second PLMN associated with at least one second parameter within the defined time period, the second PLMN providing access to the at least one type of service, the at least one second parameter being different from the at least one first parameter.

Methods and user equipment for recovering from issues of connectivity between a PLMN and a UE

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.

User equipment and method for handling public land mobile network selection involving prose communication

Methods and apparatuses are provided that prevent a user equipment (UE) from entering into a permanent out of service (OOS) state. The UE receives a registration reject message associated with a permanent cause when the UE triggers a registration request for registering with a first network entity. It is determined whether the UE was previously registered with a second network entity upon receiving the registration reject message associated with the permanent cause. The UE stores a network entity identifier of the first network entity in a temporary forbidden list when the UE was previously registered with the second network entity, to prevent the UE from entering into the permanent OOS state.
