Abstract: 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.

Abstract: An apparatus includes, in some embodiments, at least one processor and at least one memory storing instructions which, when executed by the at least on processor, causes the apparatus at least to receive a multicast service area update request comprising information defining a change in multicast service area for a multicast service session. A user equipment affected by the changed multicast service area is determined, as is a location of the user equipment affected by the changed multicast service area. It is determined whether the user equipment affected by the changed multicast service area is within the changed multicast service area. A protocol data unit session of the user equipment affected by the changed multicast service area is modified with information about the changed multicast service area, based on determining whether the user equipment affected by the changed multicast service area is within the changed multicast service area.

Abstract: 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.

Abstract: 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.

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: There is provided an apparatus comprising: means for storing at least one flag in a first state at a first time, wherein the at least one flag is associated with at least one user equipment and the first state indicates that no policy association is required for the at least one user equipment; means for receiving, at a second time which is after the first time, a request from a network exposure function indicating that the at least one flag should be updated to a second state, wherein the second state indicates that a policy association is required for the at least one user equipment, wherein a purpose of the policy association is to satisfy service requirements of a service which has been or will be provisioned at the at least one user equipment; and means for, in response to receiving the request, updating the flag to the second state.

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.

Abstract: Apparatuses, method, and computer-program for a mobile telecommunication network comprising multiple public land mobile networks sharing a radio access network node are provided. An apparatus of one of the multiple public land mobile networks may include at least one processor; and at least one memory comprising: instructions which, when executed by the at least one processor cause the apparatus at least to: receive, from an application function of a content provider, a request for allocation of a temporary mobile group identity for a shared multicast/broadcast session comprising an index value to be used to select a temporary mobile group identity for the shared multicast/broadcast service from the list of temporary mobile group identities for shared services; select, based on the index value, a temporary mobile group identity for the shared multicast/broadcast service from a list or range of temporary mobile group identities for shared services; and send, to the application function, the selected temporary mobile group identity for the shared multicast/broadcast service.
