Abstract: Systems and techniques for packet switched connection management. Upon a handover/cell change request with change of routing area code, an examination is made of parameters associated with a user equipment affected by the request for indications that the user equipment is engaged in a packet switched connection. Conditions associated with the handover/cell change request to determine if the packet switched connection should be released. If conditions associated with the handover/cell change request do not indicate that the packet switched connection should be released, release of the packet switched connection is inhibited.

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: Various communication systems may benefit from the use of relayed packet data connection. Moreover, such communication systems may benefit from methods and systems for the establishment of a packet data network connection for a proximity services user equipment via a relay user equipment. A method can include establishing a packet data network connection between a relay user equipment and a packet data network gateway. The method can also include establishing a relay connection between a proximity services user equipment and the packet data network gateway. The relay connection can be a connection within the packet data network connection.

Abstract: Communication systems, such as an evolved packet system, may benefit from various interworking functions. In particular, certain communication systems in which machine type communication devices are deployed may benefit from a machine type communication interworking function in a visited network. A method may comprise receiving, from a network element, a request in a visited machine type communication interworking function. The method may also comprise processing the request in the visited machine type communication interworking function. The method may further comprise sending a response to the network element in response to the request.
