  • Patent number: 7844250
    Abstract: Method and nodes involving communicating charging information (CI) in a network comprising at least a serving node (SGSN) and a gateway node (GGSN) wherein charging information (CI) relating to a particular PDP context for a given mobile station is gathered in the gateway node and transmitted in a GTP header extension to a serving node (SGSN).

  • 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.

  • Publication number: 20090291666
    Abstract: The application relates to charging of traffic from terminals and in particular of charging of traffic from GPRS mobile terminals which are roaming in a visited PLMN (not claimed). According to the applicant's acknowledged prior art, either the traffic passes the home PLMN or the Home Operator relies on the Visited Operator to generate the CDRs to be used by the Home Operator for billing. Whereas the first solution leads to tromboning and inefficient traffic routing, the second solution calls for a strong trust relationship between the Home and the Visited Operators. The present invention circumvents both problems in that the terminal generates a traffic counting information and sends it to the Visited Network. The Visited Network generates a traffic counting record comprising the traffic counting information from the terminal and traffic counting information from the Visited Network. The traffic counting record is subsequently sent to the Home Network.

  • Publication number: 20080311927
    Abstract: The present invention relates to a system for providing a core network node with location related information about one or more mobile user stations accessing the core network over an access network. It comprises a number of radio access network nodes (RNC; BSC) a number of first network nodes or core network nodes serving communication of data (SGSN1, SGSN2), a number of second core network nodes comprising gateway core network nodes (GGSN) acting as gateways to external or third party controlled data communication networks and/or service providers. Location related information of one or more mobile user stations obtained from the radio network access nodes is provided from a first network node or core network node to a second core network node. Said location related information is provided in one or more dedicated information elements added to existing communication of messages between said first core network node and said second core network node.
