20100040047 | Loss of Signalling Bearer Transport - Being aware of a loss of signalling bearer transport through an IP Connectivity Access Network is an important issue. Therefore, the present invention relies on amending the Policing and Charging Control model with means to provide the IMS infrastructure with subscriptions to and notifications about signalling session events detected on the signalling IP flow transported through the bearer layer. To this end, a P-CSCF, or AF included therein, is amended to allow the establishment of a signalling session for subscription to notification of bearer level events for a signalling IP flow. Apart from that, new processing rules are required at the AF and PCRF for handling the signalling session, the notification of events and the termination of the signalling session. | 02-18-2010 |
20100049980 | METHODS AND SYSTEMS FOR BOOTSTRAPPING SECURITY KEY INFORMATION USING SESSION INITIATION PROTOCOL - Methods, systems and communication nodes for bootstrapping key establishment to exchange encryption keys between a terminal-based client and an application server using Session Initiation Protocol (SIP) signaling are described. | 02-25-2010 |
20100115598 | METHOD AND ARRANGEMENT FOR INTEGRATION OF DIFFERENT AUTHENTICATION INFRASTRUCTURES - A method is disclosed that provides efficient integration of infrastructure for federated single sign on, e.g. Liberty ID-FP framework, and generic bootstrapping architecture, e.g. 3GPP GAA/GBA architecture. An integrated proxy server (IAP) is inserted in the path between a user and a service provider (SP). The proxy server differentiates type of access and determines corresponding operative state to act as a liberty enabled server or as a GAA/GBA network application function. A Bootstrapping, Identity, Authentication and Session Management arrangement (BIAS) leverages on 3GPP GAA/GBA infrastructure to provide an integrated system for handling Liberty Federated SSO and 3GPP GAA/GBA bootstrapping procedures at the same time. The method and arrangement provides improved use of infrastructure elements and performance for authenticated service access. | 05-06-2010 |
20100131647 | Enhanced Media Control - The present invention is aimed to provide an enhanced mechanism for conflict resolution between authorized services in respect of selective authorization criteria, such as service incompatibilities, subscribed bandwidth QoS assigned per subscriber and pre-emption priority value assigned per service. To this end, the present invention provides for a new method that allows the authorization of a subsequent service as a result of applying a selective authorization criterion for the subscriber at a policy control rules server to determine those previously authorized services to be put on hold, notifying about said previously authorized services to be on hold towards application devices handling such services, and inactivating at a policy enforcement device those control rules applicable to the media associated with said previously authorized services. In addition, the method as well as the policy control rules server, the application devices and the policy enforcement device may be also arranged for re-activating said previously authorized services still on hold when the reason for being on hold has ceased. | 05-27-2010 |
20100177769 | Method and Arrangement For Handling Profiles in a Multimedia Service Network - A method and apparatus for sharing an application profile for plural public IMS identities across different IMS subscriptions. A home application profile for a first public IMS identity (IMPUx) of a first IMS subscription, is stored in its entirety at a first HSS storage. A profile reference is stored as an abbreviated foreign application profile for a second public IMS identity (IMPUy) of a second IMS subscription at a second HSS storage. The profile reference points to the home application profile in the first HSS storage. An authorizing identifier for the second public IMS identity that authorizes access to the home application profile, is also stored at the first HSS storage. | 07-15-2010 |
20100287285 | CONTROL OF QUALITY-OF-SERVICE PRECONDITIONS IN AN IP MUTIMEDIA SUBSYSTEM - The invention relates to a method of establishing a session between client user terminals accessing IP Multimedia Subsystem, IMS, networks. At least one of the IMS networks implements the use of Quality of Service, QoS, preconditions, and at least one of the client user terminals does not use QoS preconditions. The method includes receiving, at an inter-working function, IWF located in one of the IMS networks, an IMS session initiation request originated by an originating client, the request indicating a terminating client for the session. A decision is made, based on the session initiation request, that one of the originating client and the terminating client is not using QoS preconditions. A set of QoS preconditions is inserted into a procedure for establishing the IMS session on behalf of the client that is not using QoS preconditions. Session establishment is completed only after QoS resources complying with the set of QoS preconditions have been established. | 11-11-2010 |
20100333173 | System and Method of User Authentication in Wireless Communication Networks - Methods and systems taught herein provide for authentication information for authenticating a user terminal to be shared between a network entity that supports IMS-AKA authentication of the user terminal and a network entity that supports GBA-AKA authentication of the user terminal. Sharing authentication information between these entities allows all or part of the authentication information generated for IMS-AKA authentication of the user terminal to be used subsequently for GBA-AKA authentication of the user terminal, or vice versa. | 12-30-2010 |
20110022722 | POLICY AND CHARGING CONTROL ARCHITECTURE - Apparatus for generating policy and charging rules to control IP flows across a packet switched network. The apparatus comprises a first interface for coupling to an application function and a second interface for coupling to a policy and charging enforcement function implemented at a node through which said IP flows pass. A processor or processors is/are configured to receive service information at said first interface, and, via said second interface to trigger the removal of one or more pre-existing policy and charging rules at the policy and charging enforcement function following a predefined delay. | 01-27-2011 |
20110126017 | Methods, Nodes, System, Computer Programs and Computer Program Products for Secure User Subscription or Registration - The invention relates to secure user subscription or registration to a service at least partly enabled in a network. The network comprises user equipment adapted to perform generic bootstrapping. A network application function provides the service. A bootstrapping server function generates a bootstrapping transaction identifier. A home subscriber system stores a user profile, comprising information relating to the user and at least one service provided by the network application function. Corresponding communication network nodes and methods of their operation are also disclosed. | 05-26-2011 |
20120021741 | Detection And Report Of Limited Policy And Charging Control Capabilities - A method of a Home Policy and Charging Rule Function (H-PCRF) in a telecommunications network having a Home Public Mobile Public Network (HPLMN) and a Visited Public Mobile Public Network (VPLMN) includes the steps of receiving signaling messages at a network interface. There is the step of detecting dynamically from a received message with a processing unit a Policy and Charging Control (PCC) scenario with regard to PCC capabilities of a VLPMN. There is the step of sending a message from the network interface to a Home Application Function (H-AF) notifying the H-AF of the detected PCC scenario so the H-AF can decide whether to progress a service negotiation with regard to a user roaming on said VPLMN or not.
