Abstract: An apparatus and a method of selecting Public Land Mobile Networks (PLMNs) in a manual PLMN selection mode are provided. The method includes selecting a PLMN as a network that the terminal will be attached to in a manual PLMN selection mode, storing the selected PLMN in a user selection PLMN list, and selecting, when the terminal attempts recovery to receive normal services in a limited service state, a PLMN to be attached to a network based on at least one PLMN included in the stored user selection PLMN list.

Abstract: A method and an apparatus are provided for processing a Circuit-Switched (CS) call by User Equipment (UE) that is camped on a CSG cell, when a manually selected CSG cell is in a Public Land Mobile Network (PLMN), which is different from a Registered PLMN (RPLMN). The method includes registering, by the UE, with a manually selected Closed Subscriber Group (CSG) cell of a Public Land Mobile Network (PLMN), which is different from a Registered PLMN (RPLMN) of the UE; detecting the CS call; and processing the CS call in a non-CSG cell, when the manually selected CSG cell is unable to process the CS call.

Abstract: NAS signaling between a UE and a server is enhanced by performing one of: sending a registration complete message to the server using existing NAS signaling and without starting a release timer in response to receiving an RC_ID deletion IE in a registration accept message; and not sending the registration complete message to the server in response to receiving the RC_ID deletion IE in the registration accept message. A registration procedure is reinstated based on a stored RC_ID.

Abstract: Embodiments herein disclose a method for service prioritization in an electronic device comprising a plurality of SIMs associated with a single RF resource within the electronic device. The method includes sending, by an RF controller of the electronic device, a response to a second SIM to access the service associated with a second network entity. Further, the method includes configuring, by the RF controller, a signalling message comprising a category of service. The category of service indicates a priority of the service to be accessed by the second SIM. Further, the method includes sending the signalling message comprising the category of service to the second network entity.

Abstract: A method for handling an ATTACH reject message with packet radio service mobility management reject cause number (#14 cause) at a user equipment (UE) is provided. The method includes receiving, at the UE, an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity, wherein the PLMN is in a “forbidden PLMNs for general packet radio service (GPRS) service” list, detecting, by the UE, that the UE's evolved universal terrestrial radio access (E-UTRA) capability is disabled, and enabling, by the UE, the UE's E-UTRA capability and removing the PLMN from the “forbidden PLMNs for GPRS service” list.

Abstract: A method and system for enabling a User Equipment (UE) to quickly recover back to normal service on failure of registration attempt to a selected Closed Subscriber Group (CSG) cell or loss of coverage of the selected CSG cell is provided. The method provides a UE behavior during manual CSG selection mode when the selected CSG cell is associated with a different Public Land Mobile Network (PLMN) than the Registered PLMN (RPLMN) of the UE. The method also defines the UE actions to handle a user request to change a current Public Land Mobile Network (PLMN) selection mode and handle expiry of a Home PLMN (HPLMN) timer in the UE, when the UE is attached to the selected CSG cell in the manual CSG selection mode.

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.

Abstract translation: 公开了一种在跟踪区域更新过程（TAU）完成之后使用现有的非接入层（NAS）信令连接用于未决的上行链路信令/数据的方法和系统。 当用户设备（UE）正在等待TAU接受时，所提出的方法处理EPS会话管理（ESM），短消息服务（SMS）或语音呼叫或数据。 该方法允许UE在TAU完成消息中通知具有特定信息元素（IE）的网络，使得网络将采取下一个动作。 这将有助于为用户提供快速的服务。 在TAU完成后，使用“CONN REQ TYPE”IE来处理E-UTRAN（演进UTRAN）网络中所有用于电路交换（CS）业务/数据业务的异常情况。
