Abstract: According to methods for service based mobility management, a map between a plurality of service classes and/or message types and a plurality of predetermined contents of data packets is acquired (S101, S201, S301). A service class and/or message type is detected for an incoming request message (S102). A predetermined content of a data packet corresponding to the service class and/or message type is determined from the map (S103). The incoming request message is forwarded (S104) in the data packet including the predetermined content. Then, the predetermined content of the data packet is detected (S202), the service class and/or message type corresponding to the predetermined content is determined (S203) from the map, and the incoming request message is forwarded (S204) in a data block including a predetermined indication of the service class and/or message type determined.

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: User plane data is communicated by cell-specific broadcasting of said user plane data in a cell and unicasting in parallel the same user plane data to at least one communication device participating a group service. When receiving the user plane data, a communication device receiving the eel- specific broadcasting and unicasting can combine the broadcast and unicast user plane data.
