  • Publication number: 20110310906
    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 up- link direction.

  • Publication number: 20110082776
    Abstract: A node for a telecommunications system, comprising a PCEF and interfaces towards a BERF, a PCRF, and an OCS, an Online Charging System. The node is equipped with a function for sending a credit authorization request and event information to the OCS, and for receiving, in reply, a credit authorization trigger from the OCS. The node also comprises a function for forwarding such credit authorization triggers to the PCRF and for receiving from the PCRF acknowledgment of installation in the BBERF and information regarding the events for which credit is sought. The node comprises a function for receiving the result of a comparison between the event information that was sent to the OCS and the event information that was received from the BBERF; if those two are not similar, the credit authorization is not considered completed.

  • Publication number: 20110041182
    Abstract: A device for use in a cellular communications system, the device being provided with means for inspecting traffic packets to and from users in the system and for a first classification of said packets according to predetermined rules. The device also comprises means for initiating a process for a user who is the destination or source of a packet which is classified in said first classification as belonging to a specific kind of traffic which has as one of its characteristics that the device cannot redirect the packet from its intended destination to another destination. The process is such that at a later point in time, when the user attempts to access a webpage, the user is redirected to a predefined webpage.

  • Publication number: 20100311392
    Abstract: The present invention handles Authentication, Authorization and Accounting (AAA) applications in an efficient manner. The present invention is a session aware Diameter relay agent that correlates sessions that require binding and relay sessions to the same AAA server, such as a Policy and Charging Rules Function (PCRF) server. In one embodiment, the relay agent may be arranged to select a Diameter server and forward the user equipment (UE) request to the respective server while registering the server selection. The Diameter server may be a PCRF server.

  • Publication number: 20100146596
    Abstract: A method (300) for a wireless telecommunication system (200) with user equipment, UE (110), and a first node (120) to which a UE may send a request for access to a service, and a control function (160) with information about the access rights to specific services for UEs in the system. The system (200) comprises an interface (150) between said first node (120) and the control function (160), and the method (300) comprises the step (3) of letting said first node receive information about a UE's access rights from said control function, and letting said first node handle access requests to a service from a UE using the access rights information from said control function. The method additionally comprises the step (3) of letting the access rights information from said control function to said first node comprise a code (X, Y, Z) regarding services to which the UE is denied access.
