Abstract: 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.

Abstract: 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.

Abstract: Systems, methods, apparatuses, and computer program products of policy control for 5G multicast-broadcast services (5MBS) are provided. One method may include, when a multicast distribution session begins, selecting, by an ingress node, a control node for the multicast distribution session. The method may also include attempting to establish a policy association for the multicast distribution session with the control node, receiving a failure reply from the control node for establishing the policy association including an identifier of an already assigned second control node, establishing a policy control association related to the multicast distribution session with the second control node, providing the identifier (ID) of the multicast distribution session to the second control node, and receiving policies related to the multicast distribution session from the second control node.

Abstract: Methods, apparatuses and computer program codes for controlling a broadcast session by stations in a session service area are disclosed. A message related to a broadcast session is received (100) from a session management function, whereafter an updated information record regarding stations associated with the broadcast session is generated (102). It is determined (104) whether there is a change between the updated information record and an earlier information record regarding stations associated with the broadcast session. A session control message is sent (106) accordingly to at least one station.

Abstract: There are provided measures for service based communication between access networks and core networks. Such measures exemplarily comprise, at a first network entity, noticing that a first abstract syntax notation (1) encoded next generation application protocol packet data unit is to be sent to a second network entity, encapsulating said first abstract syntax notation (1) encoded next generation application protocol packet data unit into a first hypertext transfer protocol message, and transmitting said first hypertext transfer protocol message towards said second network entity, wherein said first network entity is an access network entity and said second network entity is a core network entity, or wherein said first network entity is a core network entity and said second network entity is an access network entity.

Abstract: There is provided an apparatus comprising means for: receiving at least one paging request from an access and mobility management function; transmitting a service request in response to the at least one paging request to the access and mobility management function; receiving one or more activation times in the at least one paging request or in response to the service request, wherein the one or more activation times indicate the time(s) when transmission of data starts; and starting reception of data and/or reception of paging request for data at the one or more activation times.

Abstract: Systems, methods, apparatuses, and computer program products for multicast-broadcast service (MBS) deactivation and/or activation are provided. One method may include receiving, at a multicast-broadcast session management entity, a multicast-broadcast service (MBS) session setup message, from at least one management entity, comprising at least one of an identifier of at least one network node requesting setup of the multicast- broadcast service (MBS) session and an identifier of the at least one management entity. The method may also include storing, at the multicast- broadcast management entity, at least one of the identifier of the at least one network node, the identifier of the at least one management entity, or an identifier of a region of the at least one management entity.

Abstract: An apparatus, comprising at least one processing circuitry, and at least one memory for storing instructions to be executed by the at least one processing circuitry, wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least to receive a request for joining a terminal endpoint device to an established multicast session; based on the received request, subscribe at a network entity to one or several notifications, the one or several notifications indicating whether data to be transmitted for the established multicast session is available for multicasting; obtain a subscribed notification from the network entity if data for the established multicast session is available for multicasting; and responsive to the obtained subscribed notification, issue for the established multicast session a downlink data notification for the terminal endpoint device.

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.
