Abstract: A method and arrangement for providing information to a client from a client access network regarding a requested set of users, at least some of which are connected to other access networks. In response to a client subscription request, the client access network establishes a network subscription with the other access networks. Information updates regarding users in the set are then continuously received and stored in a database of the client access network, whenever the users change their state. In response to a subsequent request for user information from the client, corresponding stored user information is retrieved from the database and sent in a notification to the client.

Abstract: A method is disclosed for use in a telecommunications network that makes use of the Session Initiation Protocol (SIP). The method comprises receiving node status information in a SIP Request whose Request Uniform Resource Identifier, or Request-URI, identifies the SIP Request as comprising node status information and also identifies the intended recipients of the node status information.

Abstract: A method and arrangement for handling a service request in a session control unit in a multimedia network. Upon receiving the service request from a user equipment, the session control unit checks a service profile associated with a user-identity of the service request in order to find an application server to which the service request is to be routed. Prior to routing the service request, an ensuring entity ensures the service request will include a primary user-identity. In the application server, the primary user-identity is used to find stored data, which is necessary for executing the requested service.

Abstract: There is described a system which, in a voice over IP radiotelecommunications system, allows a mobile station to make an emergency call, even though other calls would not be allowed at that time.

Abstract: The present invention relates to an apparatus for corrugating a web of sheet material in a continuous process by means of an elongated mold movable in an endless closed path and composed of plate elements disposed in a row the one behind the other and in one straight portion together constituting a forming table having preferably diagonally extending, mutually parallel, grooves.The plate elements are by means of journals supported on and mounted in driving members disposed on either side of the path and equipped with turning wheels, the individual plate elements following the driving members with the same side facing upwards during the whole trave along the closed path.The primary field of application of the product manufactured in the apparatus are corrugated sheet pieces intended to form the fill in contact or exchanger bodies for two fluids, of which one may be a liquid, such as water, and the other a gas, such as air.
