摘要： A method and apparatus for determining whether to allow attachment of a mobile terminal to a Radio Access Network. A selection function node receives an indication that the mobile terminal has requested to attach to the Radio Access Network. A determination is made of a property of a radio connection on both an uplink and a downlink between the mobile terminal and the RAN. On the basis of the determined property, a further determination is made as to whether to allow attachment of the mobile terminal to the RAN.

摘要： A method for controlling IP flow mobility is performed in a communication network comprising 3GPP and non-3GPP access networks, wherein a UE has an IP flow mobility PDN connection set up towards the communication network. The method comprises triggering sending to the UE, a number of IP flow specific RAN assistance parameter values for controlling the UE to route an IP flow of the IP flow mobility PDN connection either over the 3GPP access network or the non-3GPP access network. The IP flow specific RAN assistance parameters may be threshold parameters setting a limit for when to route an IP flow to the 3GPP access network or when to route the IP flows to the non-3GPP access network.

摘要： A method and apparatus for addressing a message sent from a proxy node to a peer node in a communications network. The proxy node receives from a host node a plurality of multipath messages. Each message of the plurality of multipath messages has an address. The proxy node then applies a rule to assign an address for a single flow message towards the peer node. The single flow message comprises each message of the plurality of multipath messages. The single flow message is then sent towards the peer node.

摘要： A method of a PGW may improve handover in a network including a 3GPP access network and a non-3GPP access network. For a UE, an IP flow mobility PDN connection is may be set up towards the network. Information may be obtained that for the IP flow mobility PDN connection, there is a first bearer in a first access network, which first bearer has an access parameter with a first value, the first access network being either the non-3GPP access network or the 3GPP access network. Setup of a second bearer may be triggered in a second access network that has an access parameter with the first value, when, for the IP flow mobility PDN connection, there is no bearer that has an access parameter with the first value in the second access network.

摘要： A method, implemented by a network node, for establishing an efficient dummy network connection between a mobile device and a first network includes establishing at least one data connection between the mobile device and the first network. The method further includes receiving a request to establish the efficient dummy network connection. The method also includes establishing the efficient dummy network connection after receiving the request, where the efficient dummy network connection that is established uses a minimum number of network resources, said minimum number of network resources being less than the number of network resources used in the at least one data connection.

摘要： It is presented a method for handing over a data bearer for traffic of an IFOM packet data connection between a packet data network and a mobile terminal from one access network to another access network. The method is performed in a packet data network gateway, and comprises the steps of: receiving a handover message, the handover message comprising a request to handover a source data bearer for the mobile terminal from a first access network to a second access network, wherein the first access network is a 3GPP network and the second access network is a non-3GPP network, or vice versa; transmitting a first routing rule; applying the first routing rule for downlink traffic; and establishing, when there is no matching data bearer, a new data bearer over the second access network, the new data bearer having a second routing rule matching the first routing rule.
