Patent application numberDescriptionPublished
20110004754Method And Apparatuses For Authentication And Reauthentication Of A User With First And Second Authentication Procedures - A method of authenticating a user to a network, the user being in possession of first and second authentication credentials associated respectively with first and second authentication procedures. The method comprises sending a challenge from the network to the user according to said second authentication procedure, receiving the challenge at the user and computing a response using said first credential or keying material obtained during an earlier running of said first authentication procedure, and said second credential, sending the response from the user to the network, and receiving the response within the network and using the response to authenticate the user according to said second authentication procedure.01-06-2011
20110004758Application Specific Master Key Selection in Evolved Networks - An authentication method comprises providing a set of N plural number of master keys both to a user terminal (01-06-2011
20110034157Method and apparatus for controlling communications - A method and an apparatus for controlling a communication established between terminals through COMM EST 02-10-2011
20110040855SYSTEMS AND METHODS OF REDUCING SIGNALING IN A NETWORK HAVING A DATABASE SERVER - In one aspect of the invention, a system and method reduce central database signalling. The system and method select a gateway in response to an event; determine whether to transmit a gateway identifier identifying the selected gateway to a central database; and indicate whether the gateway identifier has been transmitted to the central database.02-17-2011
20110093919Method and Apparatus for Determining an Authentication Procedure - A server for managing the authentication of clients that are subscribers of a home domain within which the server is located, the server comprising means for determining whether a client that is attached to a visited domain is to be authenticated by the home domain or by said visited domain, and for signalling the result to said visited domain.04-21-2011
20110093933AUTHENTICATION IN A COMMUNICATIONS NETWORK - A method of authenticating a user in an IP Multimedia Subsystem network, the method comprising receiving from an access network an access identifier defining a terminal's physical location, retrieving from a database a registered access identifier associated with the user; and determining if the received access identifier matches the registered access identifier, and if so then authenticating the user in the IMS network, and if not then performing an alternative authentication method. The method allows a nomadic user in the access network to register with an IP Multimedia Subsystem network.04-21-2011
20110111734Methods, Apparatuses and Software for Providing the Service Control Node with Filter Criteria - A method and apparatus in a telecommunication network for triggering services provided to a user. A service control node in the user's home network domain utilizes filter criteria, which may be derived from the user's user profile, to trigger the services. The service control node selects at least one filter criterion depending on the criterion's relevance to the user. Alternatively, the service control node is provided with at least one filter criterion not stored in the user profile.05-12-2011
20110119357Methods and Apparatuses for Terminating an IP Multimedia Subsystem Service When IP Address is No Longer Allocated to the User - A method of terminating an IP Multimedia Subsystem enabled communication service involving a user terminal, the terminal having been allocated an IP address by an access network used by the terminal to access the communication service. The method comprises determining when the IP address is no longer allocated to the user by the access network, and as a consequence of the determination, terminating the IP Multimedia Subsystem communication service.05-19-2011
20110158181Mechanism To Uniquely Identify And Unify A User's Set Of Packet Bearer Contexts In A Mobile Telecommunications - A traffic plane entity (e.g., user plane entity (UPE), serving gateway (S-GW)) and method are described herein for allocating a unique identifier (e.g., UPE/S-GW UE-Context-Id) which identifies and unifies a set of bearers within a UE context that is associated with a given UE. In operation, the traffic plane entity can then send the allocated unique identifier to another entity (e.g., mobility management entity (MME)) which at a subsequent time re-sends the unique identifier back to the traffic plane entity along with a request to have the traffic plane entity perform a specific operation or procedure on the bearers associated with the UE context of the given UE. Upon receiving the request, the traffic plane entity uses the unique identifier to perform the requested operation or procedure simultaneously on all of the bearers associated with the UE context of the given UE.06-30-2011
