摘要： 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.

摘要： There is provided an apparatus comprising means for receiving one or more wake up times, wherein the one or more wake up times correspond to one or more multicast service session times, respectively: means for waking up at the one or more wake up times; and means for starting reception of multicast data and/or means for receiving paging request for multicast data on the one or more wake up times.

摘要： There is provided a network apparatus configured to receive from a core network function a request to discover at least one access network node serving a user equipment, the request comprising a first user equipment identifier for identifying the user equipment in a core network; and use the user equipment identifier to provide to the core network function a second user equipment identifier identifying the user equipment in the access network, and at least one access network node identifier identifying at least one access network node in the access network that serves the user equipment.

摘要： Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast failure with restart are provided. For example, a method may include detecting a restart of a multicast/broadcast user plane function that was supporting a packet forwarding control protocol session for a multicast/broadcast session. The method may also include re-creating a packet forwarding control protocol session for the multicast/broadcast session. The method may further include providing addressing information for the data delivery of the broadcast/multicast session to the multicast/broadcast user plane function and instructing the multicast/broadcast user plane function to use this addressing information for the broadcast/multicast session if possible.

摘要： Methods, systems, apparatuses, and computer program products are provided for joining a multicast session of a communications network. In this regard, a control plane (CP) join request for a multicast service is received from user equipment. Furthermore, provision of a reject message associated with the CP join request to the user equipment is caused in response to a determination that a multicast distribution session is not available for a multicast address associated with the CP join request.

摘要： There are provided measures for optimization of network function profile administration and discovery. Such measures exemplarily comprise, at a network entity in a network entity composition, transmitting, towards a network repository function, a network entity registration request including an identifier of said network entity, an identifier of said network entity composition, and network entity specific attributes of said network entity, and receiving a network entity registration response indicative of a result of said network entity registration request.

摘要： Systems, methods, apparatuses, and computer program products for individual delivery of location-based multicast services are provided. One method may include receiving, by a session management node, information that a user equipment is participating in a multicast session, determining that the UE is served by a radio access node that does not support multicast sessions, and determining that the multicast session is only to be delivered to one or several service areas. In response to determining that the UE is served by a radio access node not supporting multicast and that the multicast session is only to be delivered to one or several service areas, the method further comprises subscribing to at least one notification from at least one access and mobility management node.

摘要： Systems, methods, apparatuses, and computer program products for distributing multicast packets in individual protocol data unit (PDU) sessions are provided. One method may include receiving, at a user plane node, a request from a session management node, to receive packets for a multicast session and/or to send packets from the multicast session within a protocol data unit (PDU) session. The method may also include determining whether the user plane node was already configured to receive incoming packets for the multicast session, and informing the session management node as to whether the user plane node was already configured to receive the incoming packets for the multicast session.
