Abstract: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include attaching, by a user equipment, to a visited public land mobile network as inbound roamer. The user equipment then receives a service announcement comprising at least one of a multicast service session allowed to be accessed by inbound roamers indication or multicast service class. The user equipment determines whether the user equipment is allowed to access a multicast session or multicast service class in the visited public land mobile network. The user equipment transmits, in response to determining that the user equipment is allowed to access, a request to join a multicast session comprising an identifier of the multicast session and/or a multicast service class. The user equipment receives an indication of an acceptance or rejection of the request to join the multicast session.

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: Systems, methods, apparatuses, and computer program products for roaming of multicast MBS services. One method may include receiving, by a user equipment attached to a public land mobile network as an inbound roamer, a service announcement for a broadcast session or service class indicating whether inbound roamers are allowed to access the broadcast service or service class; determining, based on the service announcement, whether the user equipment is allowed to access a broadcast session or service class in the public land mobile network; and in response to determining that the user equipment is allowed to access a broadcast session or service class in the public land mobile network, transmitting, by the user equipment, a multicast/broadcast service interest indication associated with the broadcast session or service class upon completion of a radio resource request.

Abstract: Methods, computer program products, and apparatus are provided for communicating information regarding support of broadcast transmission in a requested multicast and broadcast services (MBS) service area. An access and mobility function (AMF), application function (AF), network repository function (NRF), network exposure function (NEF), multicast and broadcast session management function (MB-SMF), or a network repository function (NRF) may communicate or receive communication relating to support of MBS broadcast transmission in a requested MBS service area.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: According to an aspect, there is provided an apparatus configured to perform the following. The apparatus receives a service announcement of a multicast broadcast service. The service announcement comprises either at least one frequency selection area identity, FSAI, and at least one indication indicating that the at least one FSAI is defined for reduced capability terminal devices or at least one frequency and at least one indication indicating that the at least one frequency is defined for reduced capability terminal devices. The apparatus performs a cell reselection process based on cell measurements and the service announcement.

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: 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.
