  • Patent number: 8621582
    Abstract: Methods, interface, and a communication network in a 3GPP network are presented. A user is authenticated and application service rules are binded to the user in GGSN filters ensuring that the correct charging, QoS level or similar function rules apply to the user for specific application services available from both external application service providers and network operator supplied specific services.

  • Patent number: 8315227
    Abstract: A network architecture comprising at least one core network, each core network comprising a number of packet data gateway access supporting nodes GASNs handling mobile user station access over an access network, said core network(s) further providing access to one or more global packet data communication networks (IN), and one or more nodes holding subscriber or mobile user station related information. The GASNs are further adapted to support intercommunication over a mobility protocol interface to, at reception of a request for change of access type from a mobile user station, establish information about the previous GASN of the mobile user station, and to, using the established information, update an established communication context concerning the mobile user station or create a new communication context concerning the mobile user station such that mobility between different access network types is enabled for a mobile user station without interruption of an ongoing session.

  • Patent number: 7843860
    Abstract: The present invention relates to an arrangement in a communications system participating in user station (UE; 1) service request and/or access procedures and comprising a number of packet data support nodes (10), a number of charging and/or policy handling nodes (30) and a number of application functions (20) handling mobility management and call control of mobile user stations requesting and/or accessing services. The packet data support node(s) (10) comprise(s) means adapted to send first mobile user station identity related information over a first interface (Gx,Gy; Gx/Gy) to a charging and/or policy handling node (30), at reception of a request for bearer services from a mobile user station (1). The application function(s) (20) comprise(s) means for, at reception of a request for a service session (SIP) from a mobile user station (1), sending second mobile user station identity related information to the charging and/or policy handling node (30), over a second interface (Rx,Rx/Gq).

  • 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.

  • Patent number: 7343497
    Abstract: A method of facilitating the interworking of network elements of one or more communication networks some of which network elements support a given security mechanism and others of which do not. The method comprises, at each network element which does support the security mechanism, maintaining a database listing peer network elements and an indication of whether or not the peer network elements support the security mechanism. Upon initiation of a signalling communication from a peer network element supporting the security mechanism to another peer network element, inspecting the database of the initiating network element to determine whether or not the peer network element supports the security mechanism, and conducting the communication accordingly. The databases 9 stored at network elements are updated dynamically based upon signalling information received from peer network elements.

  • Publication number: 20070214266
    Abstract: The present invention relates to a system comprising at least two resources (3) and a hash function (4), which system is arranged for distributing external users (1) to the resources (3), where the number of users (1) is larger than the number of resources (3). Further, the system comprises means (5) for, at least to a part, creating a uniform distribution. Preferably, the uniformness of the distribution is created by means of an encryption algorithm (5). The present also elates to a method according to the above.

  • Publication number: 20030074553
    Abstract: A method of facilitating the interworking of network elements 4,5,6 of one or more communication networks 1,2,3, some of which network elements 4,5,6 support a given security mechanism and others of which do not. The method comprises, at each network element 4,5 which does support the security mechanism, maintaining a database 9 listing peer network elements and an indication of whether or not the peer network elements support the security mechanism. Upon initiation of a signalling communication from a peer network element 4,5 supporting the security mechanism to another peer network element, inspecting the database 9 of the initiating network element to determine whether or not the peer network element supports the security mechanism, and conducting the communication accordingly. The databases 9 stored at network elements are updated dynamically based upon signalling information received from peer network elements.
