Abstract: There are provided measures for enabling/realizing broadcast session establishment, particularly improved broadcast session establishment within a multicast/broadcast service. Such measures exemplarily comprise that an access management element or function in a mobile communication system issues, in response to a request of broadcast session establishment from a session management element or function, one or more requests of broadcast session establishment operation to one or more radio access elements or functions, issuing a response of broadcast session establishment to the session management element or function, and provides an indication of completion of broadcast session establishment operation at the radio access elements or functions to the session management element or function upon obtaining a response of broadcast session establishment operation from all of the radio access elements or functions.

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 and apparatus, including computer program products, are provided for packet forwarding control protocol (PFCP) message bundling. In an example embodiment, an apparatus comprises at least one processor and at least one memory including computer program code. In some embodiments, apparatus can be configured to: determine that more than one control protocol messages should be sent between a control plane entity and a user plane entity or said user plane entity and said control plane entity; determine the control plane entity and the user plane entity support sending and receiving a single datagram carrying more than one control protocol messages; extend a header of each control protocol message to indicate that the datagram is carrying more than one control protocol messages; combine one or more message types and respective message elements of the more than one control protocol messages into the single datagram; and cause sending said single datagram.

Abstract: A network access node receives an indication of an interval between expected receptions of echo requests that pass through a tunnel that uses an interface between a network element in a core network of the cellular network to the network access node of the cellular network. The network access node determines a threshold time period based on the interval, detects there has been no echo request for a time period greater than the threshold time period, and determines that a failure has occurred of the tunnel that uses the interface. The network access node triggers set up of a new tunnel using the interface due to the failure of the tunnel. Multiple techniques are disclosed for determining that this failure has occurred and recovering from the failure, including setting up a new MBS session or using a new transport address for a current MBS session.

Abstract: A H-SMF receives, from a V-SMF in a VPLMN, a join request originating from a UE roaming in the VPLMN to join a multicast multicast and broadcast services (MBS) session, and determines whether the UE is authorized to join the multicast MBS session based upon a local configuration in a home public land mobile network, information received from an application function during establishment of the multicast MBS session, and/or user subscription data received from a user data manager. The H-SMF at least one of: transmits to the V-SMF, if the UE is authorized, an acceptance response configured to establish at least one unicast QoS flow corresponding to multicast QoS flow information received from a H-MB-SMF, or, if the UE is not authorized, a rejection response comprising error cause information indicating that the UE is not authorized to join while roaming.
