摘要： Systems and methods are disclosed for Network Slice Admission Control Function (NSACF) triggered User Equipment (UE) deregistration. In one embodiment, a method performed in a communications system comprises, at a NSACF, determining that one or more UEs need to be deregistered from a particular network slice and, responsive to determining that one or more UEs need to be deregistered from the particular network slice, sending a request to a network node to deregister one or more UEs from the particular network slice. The method further comprises, at the network node, receiving the request from the NSACF and deregistering one or more UEs from the particular network slice in response to receiving the request.

摘要： 本公开涉及延迟判定方法和装置，其中，所述延迟判定方法包括：响应于接收到终端发送的繁忙指示，延迟与所述终端的可达状态相关联的判定过程。根据本公开，终端可以通过繁忙指示来请求核心网延迟对终端的可达状态相关联的判定过程，避免终端的状态被错误地判定，避免后续更新状态时导致的通信资源浪费情况，例如可以延迟对终端进行去注册，避免终端仍处于核心网覆盖范围内却被错误地去注册，避免了后续终端需要重新注册导致的通信资源浪费等情况。

摘要： Certain aspects of the present disclosure provide techniques for slice-aware network selection. Particular aspects provide for a method for wireless communication performed by a user equipment (UE). The method generally includes obtaining, for one or more networks, network slicing information indicating one or more slice identifiers supported in the one or more networks, deriving a list of one or more preferred networks based, at least in part, on the network slicing information, and selecting a network to register with from the list of one or more preferred networks.

摘要： A serving network establishes a connection with a UE via an N3AN using a trusted registration procedure to establish a secure access link between the UE and the serving network via the N3AN. The serving network sends a trust indication message via the N3AN to the UE using the secure access link to identify the N3AN as trusted or untrusted. When the received trust indication message indicates the N3AN is untrusted, the serving network executes an untrusted registration procedure with the UE using the secure access link to establish the connection between the UE and the serving network. When the received trust indication message indicates the N3AN is trusted, the serving network continues execution of the initial registration with the UE using the trusted registration procedure to establish the connection between the UE and the serving network. The UE and serving network exchange messages via the established connection.
