An apparatus, in a user equipment, is provided, the apparatus comprising: at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to receive an indication whether a transmission mode for inactive/idle reception of multicast is applied for a multicast session, and based on the indication, perform procedures to enable reception of the multicast session using the transmission mode for inactive/idle mode reception.

Negotiation applicability for inactive or idle reception of a multicast service

Systems, methods, apparatuses, and computer program products for restoration of multicast/broadcast service upon multicast/broadcast user plane function failure without restart are provided. For example, a method may include detecting non-functionality of a first multicast/broadcast user plane function that was supporting a packet forwarding control protocol session context for a multicast/broadcast session. The method may also include reselecting a second multicast/broadcast user plane function. The method may further include recreating a packet forwarding control protocol session context in the second multicast/broadcast user plane function for said multicast/broadcast session. The method may additionally include receiving new addressing information for the delivery of said multicast/broadcast session data from said second multicast/broadcast user plane function. The method may also include updating a network element with the new addressing information.

Restoration of multicast/broadcast service upon multicast/broadcast user plane function failure without restart

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.

Distributing multicast packets in individual protocol data unit (PDU) sessions

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.

Restoration of multicast/broadcast service upon multicast/broadcast failure with restart

A technique comprising: receiving, at a session management function, information by which is identifiable a plurality of multicast service areas for a multicast session managed by the session management function; and directing towards a radio access network node an indication of the plurality of multicast service areas; wherein the plurality of multicast service areas is a subset of the set of multicast service areas for the multicast session.

Method and apparatus for system providing multicast services

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.

Frequency prioritization for terminal devices receiving a multicast broadcast service

Systems, methods, apparatuses, and computer program products for selecting the ingress node for a multicast distribution session are provided. One method may include receiving a request to join a multicast session, and checking a database to determine whether an ingress node for the multicast session has already been assigned or configured to handle a corresponding multicast distribution session by passing received data towards radio nodes within the multicast distribution session.

Selecting ingress node for a multicast distribution session

Systems, methods, apparatuses, and computer program products for the configuration of user device(s) for reception of point-to-multipoint transmission are provided. One method may include receiving, at a user equipment, a configuration for point-to-multipoint reception of a group-common transport channel. The configuration may include a group-common signaling configuration for a group of user equipment. The method may also include receiving, at the user equipment, a point-to-multipoint reconfiguration message using the group-common signaling configuration on the group-common transport channel from a device (e.g., a network node). The point-to-multipoint reconfiguration message may include an updated point-to-multipoint configuration. The method may then include receiving point-to-multipoint data, from the device on the group-common transport channel, based on the updated point-to-multipoint configuration.

Methods and apparatuses for configuration of user device(s) for reception of point-to-multipoint transmission

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.

Optimization of network function profile administration and discovery

Systems, methods, apparatuses, and computer program products for load and/or overload control in 5GC SBA are provided. One method may include transmitting, from a network function (NF) service consumer, overload control information (OCI) comprising scope information to a network function (NF) service producer or service communication proxy (SCP). The scope information may include at least one of: scope set to a notification uniform resource identifier (URI), or scope set to one of network function (NF) service instance, network function (NF) service set, network function (NF) instance, or network function (NF) set, and optionally a service name.

Overload control information from a network function service consumer in 5G core network (5GC) service based architecture (SBA)

There is provided an apparatus that comprises means for receiving a request from a second network function including information relating to the second network function, determining, based on the information relating to the second network function, at least one proxy function and in response to the request, providing to the second network function information relating to the at least one determined proxy function.

Apparatus, method and computer program related to information about SCP(s) and SEPP(s) stored in NRF

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.
