摘要: Embodiments of the present disclosure provides a method and an apparatus for subscribing a notification of a change of a network function. A method for subscribing to notification of a change of a network function may comprise: transmitting (S101) a subscription message to a monitoring network function; and receiving (S102) a notification from the monitoring network function to notify a change from the network function whose status is required to be monitored. The subscription message indicates of the network function. The attribute comprises a serving scope indicating one or more target served area of the network function whose status is required to be monitored. According to embodiments of the present disclosure, a simple and fast implementation for subscribing notification of change of network function may be achieved. Particularly, both the response time and the accuracy of the notification about a change of a subscribed network function may be improved.

摘要: Embodiments include method performed at a network node of a communication network, as well as network nodes configured to perform such methods. These methods include selecting, for a terminal device, a protocol data unit session identity (PDU) session identifier (ID) from a group of PDU session IDs that are not allocated to the terminal device by the communication network. In some embodiments, the group of PDU session IDs are not selectable by terminal devices. In some embodiments, the group of PDU session IDs are exclusive of a second group of PDU session IDs that are selectable by terminal devices. In some embodiments, the PDU session ID may be selected based on an evolved packet system (EPS) bearer ID and one of various mappings.

摘要: Embodiments of the present disclosure provide method and apparatus for access or RAT restriction. A method at a first access management entity of a network comprises determining that a user equipment (UE) is using LTE-M radio access technology (RAT). The method further comprises obtaining access restriction or RAT restriction data associated with the UE, wherein the access restriction or RAT restriction data indicates that LTE-M RAT type is restricted. The method further comprises determining whether the UE using LTE-M is allowed to attach or register to the network based on the obtained access restriction or RAT restriction data associated with the UE.

摘要: Methods and apparatuses for exposure of presence reporting area (PRA) functionality are disclosed for a wireless communication system. According to an embodiment, a service capability exposure function (SCEF) entity receives, from a requesting server, a first request for initiating PRA functionality for at least one user equipment (UE). The PRA functionality is used to monitor whether the at least one UE is located in at least one area of interest. The SCEF entity obtains at least one monitored result for the at least one UE from a mobility management node via a home subscriber server (HSS) or via a policy and charging rules function (PCRF) entity. The SCEF entity sends the at least one monitored result to the requesting server.
