Abstract: A technique for managing an automatically established roaming agreement between two IMS networks (102, 104) is described, wherein one IMS network (102) supports multiple proxy nodes (302, 106) at the network edge towards the other IMS network (104). A method embodiment of the technique is performed in an I-CSCF (302) of the first IMS network (102) and comprises the steps of receiving (316) a registration request of an UE (306) via a second IMS network (104); sending (324) a roaming information request indicating the second IMS network (104) to a HSS (110) associated with the first IMS network (102); receiving (326) from the HSS (110) a roaming information answer indicating information related to the roaming agreement, and forwarding (328), based on the roaming information answer, the registration request to a second I-CSCF (106) of the first IMS network (102) managing the roaming agreement.

Abstract: Techniques for managing a registration of a roaming user terminal (116) in its IMS home network (102) based on a roaming agreement between the visited IMS network (104) and the home IMS network (102) are described. According to one embodiment of the invention, a method for managing user registrations in the first IMS network (102) is provided. The method may be performed in an I-CSCF (106) of the first IMS network and comprises the steps of determining a status change in an automatically established roaming agreement with the second IMS network; and sending, based on the determination result, roaming status update information (204) to an HSS (110) associated with the first IMS network for initiating a registration update of the user.

Abstract: A method for control ling information object (102) usage in a network of information (100) wherein information objects (102) are identified by information object identities and locations of the information objects (102) are indicated by location pointing information, the method comprising receiving (5b) an encrypted information object (102), sending (7) to a resolution node (D200) a request for location pointing information of a key issuing node (D300), the request comprising an identity of the received information object (102), receiving (8) the location pointing information of the key issuing node (D300), sending (9) to the key issuing node (D300) a request for an access key (104) for decrypting the encrypted information object (102), the request comprising the identity of the received information object (102), receiving (11) the access key (104), and decrypting (12) the received encrypted information object (102) with the received access key (104).

Abstract: A method for a client node (D100) to access an information object (102) located at a node (D500) of a secured network (120) via a network of information (100) wherein information objects (102) are identified by information object identities (IDObj, ID?Obj) and wherein nodes are identified by locators (LGW, LObj), wherein the following is performed at a routing node (D102):—receiving from the client node (D100) an information object identity related to the information object (102),—sending the information object identity to a resolving node (D400) of the network of information (100), the resolving node (D400) being capable of initiating a procedure for sending to the routing node (D102) a locator of a gateway node (D200) interfacing the network of information (100) and the secured network (120),—receiving the locator of the gateway node (D200),—sending a request for the information object (102) to the gateway node (D200) according to the locator,—receiving the requested information object (102) from the gatewa

Abstract: The invention relates to a method for generating a personalized content file for a user entity using a file repair request for identifying a user. The file repair request is initiated by generating a preliminary file that is transmitted to the user entity, the preliminary file containing a predetermined placeholder. The preliminary file is transmitted to the user entity, the user entity starting the file repair request. The personalized content file is generated by replacing the predetermined placeholder in the preliminary file by a personalized content.

Abstract: A method is described for registering a node of an underlying network at an overlay network, characterized in that the node of the underlying network registers at a registration node which initiates a propagation of registration information towards the overlay network.
