Abstract: Various communication systems may benefit from a dynamic streaming service. For example, certain streaming services may benefit from an improvement in the switching between broadcast delivery and unicast delivery for a streaming service in a cellular system. A method includes receiving information about a streaming service. The method also includes determining by a network entity in a radio access network whether to deliver data for the streaming service via multimedia broadcast or unicast based on the information and predetermined criteria for evaluating the information. In addition, the method includes triggering a sending of the data via the multimedia broadcast or the unicast.

Abstract: Systems, methods, apparatuses, and computer program products for supporting local MBMS distribution are provided. One method includes receiving, by a broadcast multicast service center (BM-SC), an activate multimedia broadcast multicast service (MBMS) bearer request message to initiate an activate multimedia broadcast multicast service (MBMS) bearer request procedure. The activate MBMS bearer request message comprises at least one of information on local MBMS distribution received from a local MBMS entity (LME), or a destination area, or a destination area and an indication that preferred delivery is via local distribution. The method may further include determining whether local distribution path will be used based on at least one of information received in the activate MBMS bearer request message, or stored information about local MBMS entities.

Abstract: There is provided a method for a second network node, the method comprising: receiving a message from a first network node configured to provide a multicast-broadcast service, MBS, for a user equipment, UE, the message comprising an MBS identifier identifying the MB S and at least one data flow identifier corresponding to at least one data flow, for providing the MBS, to be offloaded from the first network node to the second network node; determining whether or not a tunnel, between the second network node and a user plane entity, associated with the MBS identifier exists; on the basis of the determining, transmitting, to the first network node, a response message indicating whether or not a new tunnel for the MBS is requested to be established; and utilizing the existing tunnel or said new tunnel requested to be established for providing the MBS.

Abstract: Various communication systems may benefit from network location reporting. For example, such reporting may be beneficial in the establishment of a multimedia broadcast/multicast service bearer for media traffic delivery from a group communication service application server or other similar device or system. A method can include reporting at least a first set of user equipment location information and at least a second set of user equipment location information from the user equipment to at least one network node for broadcast bearer management. The first set of user equipment location information can include a serving cell identity of the user equipment. The second set of user equipment location information can include at least one identity of at least one network service area for media broadcasting.

Abstract: Multicast and/or broadcast service may be provided to one or more radio access networks, such as using one or more multicast broadcast gateways and/or one or more nodes, such as coordination function nodes. A multicast broadcast gateway may be connected to a node via a control plane interface. The node may be associated with a base station configured to provide one or more of multicast transmissions or broadcast transmissions to user devices from a broadcast multicast core network. The multicast broadcast gateway may also be connected to the base station via a user plane interface. The multicast broadcast gateway may send, to the node and via the control plane interface, one or more control signals. The multicast broadcast gateway may send, to the base station and via the user plane interface, one or more user signals. The multicast broadcast gateway and/or node may be used to setup, update, and/or stop multicast and/or broadcast sessions.

Abstract: A method and apparatus may include establishing a first bearer for user equipment to transmit uplink communication to an application server. The user equipment is configured for vehicle-to-vehicle or vehicle-to-infrastructure communication. The method may also include establishing a second bearer for the application server to transmit downlink communication to the user equipment obtaining V2X services. The method may also include transmitting uplink and downlink communication between the user equipment and the application server.
