Abstract: Various communications may benefit from enhancements for group communication. For example, evolved packet system including an evolved multimedia broadcast/multicast service may benefit from such enhancements. For example, a method may include preparing a list of area names, identities, or both area names and identities to a network element. Moreover, a method may also include requesting the network to broadcast data to a broadcast area defined by the list. The list can define an allowed area, a broadcast area, or both.

Abstract: There are provided measures for improvements in dual connectivity for different access networks. Such measures exemplarily comprise providing control in a control plane for a terminal (UE) for access to a first access network (5G), wherein a coverage of the first access network (5G) at least partly overlaps a coverage of a second access network (4G), the terminal is capable of having access to the first access network (5G) and to the second access network (4G) in parallel, and access for the terminal to a respective access network (4G, 5G) is routed in a user plane via a respective distinct access network entity (eNB, SGAP) and to a respective (compatible) gateway (S-GW, uGW).

Abstract: Various communication systems may benefit from improvements in communication flow. For example, a network may benefit from packet flow optimization. A method can include receiving a flow at an entity of a communication system having a virtualized control plane. The method can also include dynamically deciding how to route the flow to an entity selected from a group of entities comprising at least one virtualized part of an entity. The method can further include routing the flow as decided.

Abstract: Systems, methods, apparatuses, and computer program products for interworking between bearer-less networks and bearer-based networks are provided. One method includes receiving, by a network entity in a bearer-less network, a context request to obtain user equipment context information for a user equipment moving from the bearer-less network to a bearer-based network. The method may further include providing a context response comprising the context information to a network entity in the bearer-based network, the context information used to establish bearers for the user equipment to obtain internet protocol (IP) based services.

Abstract: An example technique may include determining, by a first base station in a wireless network, a user device has transitioned from an active state to an idle state, determining, by the first base station, a list of base stations and a list of cells corresponding to the list of base stations representing a tracking area for the user device based on a signal received from at least one second base station, the signal received from the at least one second base station including an indication of an amount of activity on at least one boundary between the at least one second base station and a plurality of third base stations, and controlling sending, from the first base station to the user device, a signal including at least one of the list of base stations and the list of cells as a tracking area for the user device.

Abstract: Various communication systems may benefit from an identifier that can correlate a user equipment or a packet data network connection with a particular cell. For example, a correlation identifier may be useful to address management of user plane congestion and other use cases. A method can include generating a correlation identifier for a user equipment and/or a packet data network connection. The method also includes the ability to identify the user context information with the same correlation ID in the core network and in the radio access network. The method can also include sending the correlation identifier to a network element.
