Abstract: Systems, methods, apparatuses, and computer program products for inter-gNB small data transmission (SDT) routing at a radio access network (RAN). A method may include transmitting an initial request message from a first element in a first network node, to a second element in the first network node to obtain context information. The method may also include receiving, at the first element, a context setup request message based on the context information containing a transport layer information of a third element of a second network node and context information of a user equipment in the second network node. The method may further include processing a data packet according to the received context information. In addition, the method may include forwarding the data packet to the third element of the second network node according to the received transport layer information.

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 herein disclosed a method for receiving, from a radio access network node, a conditional handover configuration for a plurality of target cells and a radio condition for conditional handover of the UE for a plurality of target cells. The method further comprises receiving, from the radio access network node, an indication that the UE is allowed to select and connect to a preferred target cell from the plurality of target cells. The method further comprises selecting the preferred target cell from the plurality of target cells based on network slice area of service availability information for each target cell configured at the UE and the radio condition and transmitting, a request to connect to the preferred target cell.

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: According to an example aspect of the present invention, there is provided a method comprising receiving, by an apparatus, a message while the apparatus is in a radio resource control inactive state, wherein the message comprises a first indication indicating a multicast-broadcast service session to which the apparatus has joined and a second indication indicating to remain in the radio resource control inactive state and in response to receiving the message: in case determining based at least on information received in a radio resource control message that the apparatus belongs to a subset of user equipments, initiating a resumption of a radio resource control connection, and in case not determining that the apparatus belongs to the subset, remaining in the radio resource control inactive state.

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.
