Abstract: 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.

Abstract: 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).

Abstract: A method and user equipment for handling a Public Land Mobile Network (PLMN) selection in a mobile communication network is provided. The method includes obtaining, by a User Equipment (UE), a PLMN list of one or more Radio Access Technologies (RATs) comprising a list of available PLMNs, when the UE performs a Manual Closed Subscriber Group (CSG) selection, initiating a PLMN list validation timer, and reusing the previously obtained PLMN list, when at least one predefined event is triggered and the PLMN list validation timer is running. The at least one predefined event comprises at least one of Home Public Land Mobile Network (HPLMN) timer expiration, a manual PLMN selection, the manual CSG selection, and autonomous CSG selection.

Abstract: A method and system to use existing Non-access stratum (NAS) signaling connection for pending uplink signaling/data after Tracking Area Update Procedure (TAU) complete is disclosed. The proposed method handles the EPS Session Management (ESM), Short Message Service (SMS) or voice call or data when a User Equipment (UE) is waiting for TAU accept. The method allows UE to inform the network with specific Information Element (IE) in TAU complete message, so that the network will take the next action. This will help to provide quick services to the user. Using the “CONN REQ TYPE” IE, in TAU complete, to handle all abnormal Cases for Circuit Switches (CS) services/data services in E-UTRAN (Evolved UTRAN) network.
