    Abstract: 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.

    Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes configuring, by a User Equipment (UE) (100), a Protocol Data Unit (PDU) session type as an always-ON type or a normal PDU type. Further, the method includes sending, by the UE (100), a PDU session establishment request message including the PDU session type to be the always-ON type or the normal PDU type to a network (200) during an initial PDU session establishment procedure.

    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 translation: 提供了一种用于处理移动通信网络中的公共陆地移动网络（PLMN）选择的方法和用户设备。 该方法包括：当UE执行手动闭合用户组（CSG）选择时，由用户设备（UE）获得包括可用PLMN列表的一个或多个无线接入技术（RAT）的PLMN列表，发起PLMN 列表验证定时器，并且当触发至少一个预定事件并且PLMN列表验证定时器正在运行时，重用先前获得的PLMN列表。 所述至少一个预定义事件包括家庭公共陆地移动网络（HPLMN）定时器到期，手动PLMN选择，手动CSG选择和自主CSG选择中的至少一个。
