Abstract: A method permitting the control of the service quality and/or service fees of telecommunication services in which several service nodes are involved. During the initiation and/or implementation of a communication service, an exchange of signaling data occurs between a communications terminal and at least two service nodes which are involved in the communication service. The control node detects whether the service data transmitted by the at least two service nodes relate to the very same communication service. Then the control node selects service data from the transmitted service data and uses these service data for controlling the service quality and/or service fees.

More specifically, it is directed to the field of Quality-of-Service (QOS) management for adaptive real-time services running on mobile devices and an End-to-End Negotiation Protocol (E2ENP) based on a novel usage of a session-layer protocol (SIP) in conjunction with extensions of a session description protocol implementation (SDP, SDPng) and the Extensible Markup Language (XML) for defining user profile and terminal capability information which allow to enforce and use hierarchical QOS Contract specifications.

Abstract: A client is intended to be authenticated with a server. The present disclosure relates to a method that includes using an algorithm for the client and server, but independently of one another, to produce a first key. A second key is produced by the client such that its distance from the first key is within a predetermined distance. The second key is sent to the server. The server successfully authenticates the client if the distance between the received second key and the first key is within the predetermined delta. The second key is used as a new start key for further authentication of the client with the server.

Abstract: The invention relates to an interactive voice response (IVR) system supplying functions and resources to services encompassing interactive voice response or output of announcements and three methods for dealing with resource bottlenecks of the IVR system. The IVR system supplies a pool of resources to several switching systems. Virtual, individually assigned IVR systems are created from the perspective of the switching systems by allocating the control interfaces and user data interfaces of the IVR system in an exclusive, disjunctive manner to the switching systems. Resource bottlenecks can be prevented when several switching systems access the IVR system by rejecting jobs for which the required resources cannot be reserved or by aborting jobs creating too substantial delays during processing due to the wait for resources. The invention has the advantage of efficiently utilizing the resources supplied by the IVR system.

Abstract: A method detects a first baseband signal sent by a first sending station via an air interface to a first radio station of a radio communications system. A first receive signal, which contains the first baseband signal superposed with at least a second baseband signal sent by a second sending station to a second radio station, is received by the first radio station. The first radio station uses at least a second receive signal received by the second radio station for detection of the first baseband signal. The second receive signal contains at least the second baseband signal, and is used to at least partially cancel the interference in the first receive signal caused by the second baseband signal.

Abstract: A method uses a relay station to assist processing of requests from user ends. The relay station acquires and monitors channel resource information received from a base station. Upon receiving a request from the UEs via the channel resource, the relay station sends the request received to the base station if it detects no response from the base station to the request. An apparatus uses a relay station to assist processing of requests from UEs. A channel resource acquisition unit acquires channel resource information from the base station. A user monitoring unit monitors the channel resource acquired by the channel resource acquisition unit and for receiving requests sent from the UEs. A base station monitoring unit monitors response from the base station to the requests upon receiving the requests sent from the UEs. A transmitting unit sends the request to the base station when no response from the base station to the request is detected.
