  • Patent number: 8995340
    Abstract: The invention discloses a user terminal (115) for a wireless communications system (100) which is arranged to establish and carry out a communications session with a gateway node (120) in the system (100) according to a first protocol over at least one bearer (110, 140). The user terminal (115) is arranged to provide a predefined issued message to the gateway node (120) during the establishment of a session with an indicator that the user terminal (115) is arranged to handle traffic to and from the gateway node (120) using a predefined version of a defined filter (130).

  • Patent number: 8787399
    Abstract: A communication system includes a user equipment (UE) 10 and a gateway 26. The UE (10) sends data packets on one or more bearers (52, 54) to the gateway 26. One or more packet filters (62, 64) are installed in the UE (10) for associating the data packets with the bearers (52, 54). A decision is performed if installation of a new packet filter (62, 64) in the UE (10) is required to map the data packets of indicated data traffic to a particular bearer (52, 54). The result of the decision may then be indicated from a policy controller (30) to a gateway (26) and/or from the gateway (26) to the UE (10). Depending on the result of the decision, the gateway may initiate signaling of the new packet filter (62, 64) to the UE (10) and/or the UE (10) may install the new packet filter (62, 64).

  • Patent number: 8774198
    Abstract: A Packet Data Network Gateway, a PDN-GW (105), arranged to receive and forward packet data of at least a first and a second service flow in both an uplink and a downlink direction, with a first access network (125) of a first kind being used for the first service flow and a second access network (130) of a second kind being used for the second service flow. The PDN-GW (105) is arranged to transmit to a PCRF (110), a Policy and Charging Rules Function, information regarding which kinds of access networks that the PDN-GW (105) can handle, and to receive, in reply from the PCRF, rules for which of said access networks (125, 130) that should be used for said service flows. The PDN-GW (105) is also arranged to use said rules to bind a service flow to an access network (125, 130) in the downlink direction and to perform access network binding verification in the uplink direction.

  • Patent number: 8755352
    Abstract: The present invention relates to a solution for handling deferred leg linking in policy and charging rules function in a telecommunications network in relation to handover between two different access technologies. The solution is provided as a nodes, system and a method for handling handover of a user equipment, i.e. UE, (101) in a telecommunications network (100) from one access technology to another access technology, comprising the steps of detecting (203) in a target access gateway, i.e. AGW, (102) that a handover state of the UE is unknown, sending (204) from the target access gateway a gateway control session, i.e. GCS, establishment message to a policy and charging rules function node (105), wherein the message comprise an indication that leg linking of a session is to be deferred until reception of corresponding control signalling from a packet data network gateway (104).

  • Patent number: 8700040
    Abstract: A method, a gateway node, a policy control node and a infrastructure network for handling a handover of a User Equipment communicating wirelessly with the infrastructure network. A first gateway node receives handover information indicative of a handover of the user equipment between two radio access networks the first gateway node determining a bearer control mode on the basis of the handover information the first gateway node transmitting control information determined on the basis of the bearer control mode to a policy control node the first gateway node controlling the bearer binding on the basis of the bearer control mode.
