Abstract: A method and radio communication system for the transmit useful information as a service to several user stations with at least one radio network controller, at least one base station and at least one user station. The radio network controller is connected to an access device in a core network. The useful information is provided to several users as a service, whereby the user stations of the users are informed before the transmission of the useful information. According to the invention, the notification for the user stations of the users at least partly comprises a request for a response and the transmission of the useful information at least partly occurs after receipt of the response.

Abstract: A method includes handing over a user equipment from a first network access node to a second network access node and, at the second network access node, not considering the first network access node as a handover candidate from the second network access node until at least one of: (a) an amount of time since the hand over from the first network access node exceeds a first threshold amount; (b) there is a change in a channel condition between the user equipment and the first access node that exceeds a second threshold amount.

Abstract: It is described a method for transmitting a synchronization signal within a cellular telecommunication network. The method includes activating a first base station of the cellular telecommunication network, informing at least one second base station, which is a potentially interfering base station with respect to the first base station, about the activation of the first base station, and broadcasting the synchronization signal by the at least one second base station with a temporarily increased transmitting power. It is further described a second base station for transmitting a synchronization signal to another base station of the cellular telecommunication network and a central network element, which is adapted to prompt a base station in order to transmit a synchronization signal. Furthermore, it is described a program element, which is adapted for controlling the described synchronization signal transmitting method.

Abstract: A first controlling node controlling a first group of controlling nodes in a radio communications system has a control link established by a control unit based on accessing a database storing information relating to connectivity relationships between the first controlling node and the first group is accessed by a control unit. When a detecting unit detects the failure of the first controlling node on the control link, a transceiver uses the information in the database to connect to the first group and restore connectivity to the first group of nodes.

Abstract: A controller of a private base station receives data on a travel time depending on a propagation delay between a private base station and a user terminal. The controller outputs a control signal to a controllable amplifier for decreasing a transmission power of the private base station if the measured travel time is longer than a predetermined reference time or quality of service is lower than reference quality.

Abstract: A user terminal receives at least one signal with information depending on a location of the user terminal. The user terminal processes the at least one signal for providing data related to the location while it is in a cell of an accessible private base station and saves the data as a reference data. After that, the user terminal receives at least one signal with information depending on the location of the user terminal and a broadcast from a private base station. The user terminal processes the at least one signal for providing data related to a location of the user terminal and compares the data and a reference data with each other. The controller enables a contact to the private base station if the data and the reference data match each other and, otherwise, disables a contact to the private base station.

Abstract: First and second network-based radio stations receive information content, i.e., useful information, transmitted by a subscriber station and control information relating to the useful information. The first network-based radio station and the second network-based radio station transmit the control information, but only the first network-based radio station transmits the useful information.

Abstract: Disclosed is a method, computer-readable memory medium and apparatus configured to reduce an occurrence of handover ping ponging of user equipment between network access nodes.

Abstract: A method of operating a MBMS (Multimeda Broadcast/Multicast service) comprises causing a network controller to broadcast (1) to all mobile stations in a cell an offer of service. The network controller requests from each mobile station an indication of interest in the offered service and receives (2) data relating to each interested mobile station enabling the position or received signal quality of each mobile station within the cell to be determined. The network controller analyses the arrangement of interested mobile stations in one or more predefined areas and requires (7) each interested mobile station which is out of range of a subsequent broadcast transmission use an alternative mechanism to receive the service. (i.e. to use a point-to-multipoint connection if it out of range, while using a point-to-multipoint connection if it is in the range).

Abstract: Method and apparatus for efficient transmission of bits of voice information through a mobile radio network, which transmission saves transmission capacities and which makes it possible to mix-in announcements or to mix the bits of speech information of a number of callers during a conference call, is enabled such that its of voice information, dependent on the event, are converted in the mobile radio network into a transcoded format, are further processed, are converted into a non-transcoded format and are transmitted in a non-transcoded format.
