    Abstract: There are provided measures for coordination of segmented service chains. Such measures exemplarily comprise, at a user plane function entity interfacing with application services of a segment of a segmented service function chain, receiving, from a session management function entity, uplink/downlink packet detection rule information indicative of forwarding between an interface towards core network based application services and an interface towards network edge based application services.

    Abstract: Methods and apparatuses for improving service continuity are disclosed. The solution comprises storing (300) information on slice remapping describing how a given net-work slice may be mapped to another network slice, receiving (302) a first message from an access node, that the node serves a terminal or has received a request to serve a terminal utilising a network slice not supported by the node and transmitting (304) based on the first message a message to a network entity responsible for session management to control the connection of the terminal, with the information on slice remapping and/or activity status of the packet data unit sessions associated with the slice not supported by the node.

    Abstract: There are provided measures for enabling/realizing radio network information exposure for edge computing, such as radio network information provisioning for/to an application hosted in an edge computing environment. Such measures exemplarily comprise that an information request of an application, running in an edge computing environment, for receiving requested network information of a network serving a communication element or function associated with the application is transformed into a dedicated network tracing request for tracing the requested network information for the communication element or function in the network, wherein addressing information of the communication element or function, included in the information request, is mapped to an identifier of the communication element or function, by which the communication element or function is identified in the network, and the identifier of the communication element or function is used in the network tracing request.

    Abstract: This specification describes apparatus comprising means for: sending, from a first network function service consumer instance to an authorisation server, a request for an access token for use in accessing a service provided by a network function service producer, wherein the request includes an identifier of a set of network function service consumer instances of which the first network function service consumer instance is a member; receiving, at the first network function service consumer instance from the authorisation server, an access token for use in accessing the service provided by the network function service producer, wherein the access token includes the identifier of the set of network function service consumer instances of which the first network function service consumer instance is a member; and sending, from the first network function service consumer instance to the network function service producer, a request to access the service provided by the network function service producer, wherein the request to access the service includes the access token.

    Abstract: Methods, apparatuses and computer program products are described that facilitate sending and receiving notifications related to user equipment being added to or leaving a multicast group or multicast stream in a network. A method can include receiving, from a session controller, a request for reporting when protocol data unit (PDU) sessions are added to/removed from a downlink replication tree associated with an internet protocol multicast flow; determining whether said PDU session has been added to or removed from the downlink replication tree associated with the internet protocol multicast flow; and, in response to said determining, transmitting a message to a session management function indicative of that said PDU session has been added to or removed from said downlink replication tree. The message can include an internet protocol address associated with a source of said added or removed multicast flow and/or the multicast destination of said internet protocol multicast flow.

    IPC: H04W48/18

    Abstract: A method comprises receiving information at a first network entity indicating a first data network identity associated with a request from a communications device; and selecting at the first network entity a second data network identity which is usable with respect to the communications device when said first data network identity is not usable with respect to said communications device, said selecting being in dependence on information associated with said communications device.
