Abstract: A technique for hiding network element names and addresses in communications between first and second networks includes providing a message generated by a network entity in the first network to be delivered to a target network entity in the second network, the messaging including first and second parts. The message generated by the network entity in the first network is routed to a contact point disposed between the first and second networks in accordance with the first part of the message and the message generated by the network entity in the first network is routed from the contact point to the target network entity in the second network in accordance with the second part of the message.

Abstract: A method provides information on a resource in a communication system. The method includes receiving a request from a first entity in a second entity, the request being addressed to a second resource. The method also includes providing a response to the request comprising a group indication when the second resource defines a group comprising a number of individual resources. Furthermore, user terminals and entities in a communication system are provided configured to implement the method.

Abstract: The present solution relates to a telecommunications system where information is maintained of communication groups available to a user terminal (UE). A communication server (PoC server) of the system is able to receive a request message (3-1) sent by the user terminal (UE), the request message (3-1) comprising an indication of the communication group the user wishes to speak to. If the request can be accepted, the communication server (PoC server) transmits a floor granted message (3-2) to the user terminal (UE). According to the present solution the communication group requested by the user is set (3-3) as the priority communication group for said user at least for a predetermined time period.

Abstract: A communication system including a first administrative subsystem and a second administrative subsystem providing group communication service. The system includes a first server for storing group and list management information of subscribers of the first administrative subsystem. The system also includes a second server for storing group and list management information of subscribers of the second administrative subsystem. Further, the system includes an interface for exchanging group and list management information between the first server and the second server. In addition, the system reduces ambiguity in group information management of integrated systems that include two or more administrative domains.

Abstract: There is disclosed a technique in which there is allocated one of a plurality of serving call state control functions to a subscriber, the technique including: receiving load information from at least one serving call state control function; and determining a serving call state control function for the subscriber in dependence on the received load information, wherein the receiving step includes receiving the load information during subscriber registration in a signal received from a serving call state control function to an interrogating call state control function.

Abstract: Disclosed herein is a method for changing characteristics of a signalling link in a communications system including at least two signalling points and at least one signalling link through which signalling information is transmitted from a first signalling point to an adjacent signalling point. The signalling traffic to be relayed is monitored at a signalling point. A procedure for modifying user connections is performed. A modification request message including an identifier value for identifying the object of modification is sent to the adjacent signalling point. The system flexibly adapts to a temporary increase in signalling load. A set of identifier values are used for identifying signalling links allocated in advance to signalling links between adjacent signalling points. When signalling traffic meets a predetermined condition, a signalling link is modified by inserting in the modification message an identifier value belonging to the set.

Abstract: The present invention relates to presentation of content to mobile users. In the method, data associated with presentation of content is transmitted from a communication system, the data including information regarding an event. The data is received at mobile user equipment and stored in a memory of the mobile user equipment. In response to the event, presentation of the content is triggered. The presentation is based on the data stored in the memory of the mobile user equipment.

Abstract: The invention relates to a method and system for establishing an emergency session in a communication system which includes at least one user equipment and one or more network entities involved in establishing an emergency session. When the user equipment initiates a session by sending a message to a network entity indicating an identifier, e.g. the call number or logical name of a called entity, one of said network entities analyses the received identifier. When detecting that the session to be initiated is an emergency session, an information is returned to the user equipment for informing the latter that the initiated session is an emergency session. The user equipment thereupon initiates the execution of an emergency session. Thus, even when the user equipment is unable to detect, by itself, that the intended session is an emergency session, the network will inform the user equipment on the emergency session for ensuring appropriate handling thereof.

Abstract: A communication system and a method and a server for a communication system is disclosed. The communication system comprises communication means for providing communication media for a plurality of user equipment, a storage entity (21) adapted to store information that associates with at least one of said user equipment, and at least one service provision entity (28) adapted to serve a client based on information stored in said storage entity. The storage entity (21) is arranged to receive information associated with the user equipment from other entities (22, 23) and to associate said received information with a respective user equipment.

Abstract: A method for monitoring a connection to a user terminal in a telecommunications system and a telecommunications system comprising an element (CSCF) controlling a connection to a user terminal (UE) and a system part (SGSN, GGSN) providing transport of user data, which system part is separate from said controlling element, wherein a system element which knows the state of the connection to the user terminal (UE) is arranged to send an indication message to the controlling element (CSCF) indicating the state of the connection, and the controlling element (CSCF) is arranged to decide the state of the connection to the user terminal (UE) based on the indication message received.

Abstract: The invention relates to changing the characteristics of a signalling link in a communications system comprising at least two signalling points (A. . . D) and at least one signalling link through which signalling information is transmitted from a signalling point to an adjacent signalling point. In the method, the signalling traffic to be relayed is monitored at a signalling point and a modification procedure intended for modifying user connections is performed, in which a modification request message including an identifier value for identifying the object of modification is sent to an adjacent signalling point.

Abstract: A method for analyzing human brain physiology and pathology according to metabolic data obtained by non-invasive means. Metabolism is detected using in vivo proton nuclear magnetic resonance spectroscopy (.sup.1 H MRS) using pulse sequences that provide nuclear magnetic resonance signals from a living human brain. Factors which might decrease performance of artificial neuronal network analysis, e.g. the residual water signal, are eliminated from the nuclear magnetic resonance signal, e.g., by means of a singular value decomposition algorithm. Moreover, the artificial neuronal network analysis accepts as input all of the metabolite resonances, not just selected features, for analysis. The artificial neuronal network analysis yields metabolite concentrations and the nature of tissue type in focal lesions, such as tumors, stroke lesions, epileptic foci, traumatic scars, and also in more diffuse pathologies such as metabolic brain disorders as well as in post-therapeutic changes.
