Abstract: 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.

Abstract: Systems and methods are disclosed for providing an enhanced Packet Forwarding Control Protocol (PFCP) association procedure for session restoration. In this regard, a method performed by a PFCP node comprises deleting one or more PFCP sessions of the PFCP node that are associated with a failed PFCP entity or with a failed PFCP path. The method further comprises sending, to a PFCP peer node, a node level message to request that the PFCP peer node delete a corresponding one or more PFCP sessions of the PFCP peer node that are associated with the failed PFCP entity or with the failed PFCP path, wherein the node level message comprises an indication of the corresponding one or more PFCP sessions. Some embodiments provide that the node level message comprises a PFCP Association Setup Request including sessions retention information to indicate whether to retain PFCP sessions associated with the PFCP Association Setup Request.

Abstract: Embodiments of the present disclosure relate to a method and an apparatus for allocating a PDU session ID for a terminal device. The method comprises: selecting (S101), for a terminal device, a protocol data unit session identity, PDU session ID, from a group of PDU session IDs. The group of PDU session IDs are not allocated to the terminal device. According to the embodiments of the present disclosure, the network node may select, for the terminal device, a PDU session ID from a group of PDU session IDs, which are not allocated to the terminal device yet. Thus, any newly selected PDU session ID may be ensured as unique.
