Abstract: The present invention is related to a method of configuring an interface between a serving GPRS support node and a base station system. A signal is transmitted (401) from the base station system to the serving GPRS support node indicating cancellation of at least one BSSGP virtual connection associated with a first network service entity identifier. Upon receipt of the cancellation signal at the serving GPRS support node, data structures in the serving GPRS support node are updated (402) to reflect that the at least one BSSGP virtual connection has been cancelled.

Abstract: Telecommunications network decision making (such as call admission and call congestion control) utilizes as input, not only information in the cell where the call is setup, but also cell condition information from cells which neighbor the cell where the call is setup. The cell condition information from neighboring cells is obtained even in situations in which the neighboring cell is controlled by another exchange, e.g., another radio network controller (RNC). In an illustrated embodiment, the cell condition information utilized by the decision making includes measured data taken over at least a multi-connection portion of cell, one example of which is radio interference information. The cell condition information utilized in the network decision making is transmitted between exchanges (e.g., between radio network controllers [RNCs] using common channel signaling.

Abstract: In a mobile radio communications system, first radio resources are allocated to a first mobile radio communication. The term “radio resources” relates to one or more resources used to support a mobile radio communication and may include, for example, radio bandwidth, transmit power, signal and data processing hardware and software resources, radio transceiving resources, etc. A second group of radio resources is allocated to a second mobile radio communication. When a block of user information needs to be transmitted that requires an additional amount of radio resources, the first and second mobile radio communications are interrupted or their service levels are reduced for a brief time period. At least part of the block of information is transmitted during that time period using at least some of the first and second radio resources allocated for the first and second mobile radio communications.

The positioning data is determined for the mobile station responsive to the positioning request indicator and transmitted back to the positioning node using a second group of ANSI-41 messages.

Abstract: A procedure for triggering a handdown or a handoff a mobile station served by a base station of a cellular wireless communication system. A tolerable path loss for signal links between the base station and a mobile station located within the base station's cell, is initially determined. A control signal is radiated at a known transmit power level from the base station over its cell. A receive power level threshold is determined for the control signal for reception by the mobile station, according to the transmit power level and the tolerable path loss. A handoff of the mobile station is triggered after deriving the received power level of the control signal at the mobile station, and determining that the received power level is less than the receive power level threshold.

Abstract: A method in a cellular telecommunications network for optimizing a current hysteresis value utilized to define a handoff border between a present cell and a neighbor cell. Pairs of signal strength (SS) measurements are collected from a plurality of mobile stations operating near the handoff border. Each SS measurement pair includes an SS measurement from the present cell and an SS measurement from the neighbor cell. A midpoint SS is then calculated by determining an average SS measurement from the present cell, an average SS measurement from the neighbor cell, and an overall average of the average SS measurement from the present cell and the average SS measurement from the neighbor cell. The method then optimizes the handoff border by subtracting from the current hysteresis value, an amount approximately equal to the difference between the midpoint SS and the average SS measurement from the present cell.

Abstract: Apparatus, and an associated method, dynamically selects values of thresholds to be used in a determination of whether to request a handoff of communications between serving and target base stations of a cellular, or other, radio communication system. Because the thresholds are dynamically determined, the thresholds are selectable responsive to communication characteristics about the mobile stations with which communications are to be handed off.

Abstract: A mobile communication system that proposes a new charging principle, according to which the roaming leg is paid entirely by the party who forwards the call to a mobile subscriber. In an exemplary embodiment, the call is first routed to the exchange of subscriber B, who has forwarded his calls. After determining that the call is to be forwarded to a mobile subscriber C, the exchange routes the call to the gateway mobile switching center (GMSC) capable of making interrogations to the home location register of subscriber C. When the charging record for the call is generated, the called subscriber B is charged for the leg between the GMSC and subscriber C. Thus, subscriber C does not have to pay for calls addressed to subscriber B. To minimize the call costs to subscriber B, as direct a route as possible is preferably used on the leg between the GMSC and subscriber C.

Abstract: In a channelized system having a plurality of channels, an input spectrum having a plurality of signals is received by a receiver (10). A first attenuation value (V1) is applied to a first variable gain device (12) and a second attenuation value (V2) is applied to a second variable gain device (14), wherein the first variable gain device (12) and the second variable gain device (14) are within a common signal path. The receiver (10) is tuned to a desired channel and a first power level is measured within the desired channel. The receiver (10) is selectively tuned to at least one additional channel and a second power level within the at least one additional channel is measured, independent of the first power level. Based on measuring the power levels, a first modified attenuation value is applied to the first variable gain device (12) and a second modified attenuation value is applied to the second variable gain device (14).

Abstract: The object of the invention is a transceiver for transmitting and receiving an RF signal on at least two operating frequency ranges. One idea of the invention is to use a transceiver based on the direct transform and where the mixing frequency is generated with the aid of the same synthesiser. This is preferably realised so that when operating on frequency ranges far from each other the output signal of the synthesiser is divided with different divisors in order to generate the mixing frequency (211, 231, 261, 281). When operating on frequency ranges which are close to each other the divisor (P) used in the feedback of the synthesiser is advantageously changed (248). With the aid of the invention two mixing signals with a mutual phase difference of 90 degrees can be generated in connection with the division of the synthesiser frequency, whereby no RC phase shifters are required in the signal line, and a good phase accuracy is obtained which is independent of the frequency.

Abstract: A method for functional testing of a transmission and reception path includes transmitting a first signal at a first transmission power level to a radio station and determining a first reception strength, with a base station. A first difference value is subsequently calculated. The radio station transmits a second signal at a second transmission power level to the base station, determines a second reception strength, and calculates a second difference value. Any difference between the difference values is then compared with a threshold value, and a function of a transmission and reception path is derived from the comparison. A base station of a radio communications system is also provided.
