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: Methods, apparatus and computer program products for binding information management. A method implemented at a policy control node in a wireless communication network comprises: obtaining information indicating a collocated deployment of a session management node and a binding support node (202); and inhibiting, in response to the information, a registration of binding information to the binding support node (204). A policy control node can know that a binding support node is collocated with a session management node, and no registration of binding information to the binding support node will be triggered for the policy control node.

Abstract: Embodiments of the present disclosure provide methods and apparatus for indirect data forwarding. A method at a mobility management node comprises sending, to a serving gateway entity in the first system, a request for creating an indirect data forwarding tunnel. The request comprises an indication flag for indicating to the serving gateway entity that an indirect data forwarding tunnel is to be created with a user plane function entity in a second system. The method further comprises receiving a response for the request from the serving gateway entity.

Abstract: A method at an Access and mobility Management Function (AMF) for facilitating a Protocol Data Unit (PDU) session procedure for a User Equipment (UE) in a 5th Generation System (5GS) network, wherein the 5GS network is interworking with an Evolved Packet System (EPS) network, and a Packet Data Network Gateway Control plane Function+Session Management Function (PGW-C+SMF) supporting the interworking is selected for managing the PDU session. The method comprises determining whether the PDU session supports interworking with the EPS network, based on at least one of a capability of the UE and a subscription data of the UE; and sending an indication which indicates whether the PDU session supports interworking with the EPS network to the PGW-C+SMF.
