  • Publication number: 20240292203
    Abstract: Methods for event report management in a network comprising a set of NF nodes, and corresponding NF nodes. The A method is implemented at a first NF node for providing an event exposure service for a User Equipment, UE, to a second NF node which subscribes the event exposure service includes starting a report mute guard timer upon receiving a first presence status report for the UE from a third NF node. The method includes avoiding a transmission of an event report to the second NF node while the report mute timer is running and transmitting an event report corresponding to a latest presence status report received during the running of the report mute guard timer to the second NF node when the report mute guard timer expires. The present disclosure further discloses a corresponding method implemented at the second NF node. The present disclosure further provides corresponding NF nodes and computer readable medium.

  • Publication number: 20240137854
    Abstract: Network nodes and methods for control thereof for dynamic network slice selection. An AMF receives a UE request originating from the UE, the UE request being any one of a registration request and a session request. A network slice requester controls a transmitter to transmit a network slice selection request to a PC_NSS. A selection data manager of the PC_NSS determines selection data specifying one or more UE specific parameters affecting network slice selection. A network slice selector selects a network slice assignable for the UE, based on the selection data, determines network slice data and a corresponding network slice routing rule, and transmits them to the AMF. A network slice manager of the AMF controls assignment of a network slice to the UE in dependence on the received network slice data and network slice routing rule.
