摘要： A method of stabilizing a communication system having base stations and mobile stations using integrated control of both signal transmission power levels and signal congestion levels. In particular, the method includes measuring a quality such as a signal to interference ratio of a signal transmitted from a mobile station to a base station and measuring a total received signal power at the base station. The signal transmission power of the mobile station is changed based on comparisons of the measured signals with predetermined threshold values. When the measured total received signal power at the base station exceeds the corresponding predetermined threshold value, a congestion control algorithm is executed to reduce the signal congestion level.

摘要： A method and apparatus for data compression in a mobile communication network. A node performing data compression on a downlink towards a mobile terminal compresses data on the basis of an identity of a decompression node. A determination is made that the mobile terminal is no longer receiving data from the decompression node owing to mobility the mobile terminal. The identity of a further decompression node from which the mobile terminal receives data is determined, and data is compressed on the basis of an identity of the further decompression node. The node performing compression can therefore dynamically adapt to mobility of the terminal, potentially resulting in a shorter learning phase.

摘要： The power levels of signals transmitted by base stations in a communication are controlled. Power level control commands are transmitted from a remote station to base stations from which the remote station receives signals to control the power levels of the signals transmitted by the base stations. A determination is made whether the remote station simultaneously receives a first signal from a first base station and at least one second signal from at least one second base station that include substantially identical message information. The first and second base stations transmit first and second reports of power levels of the first and second signals, respectively, to the controller. The controller compares the first and second reports and transmits first and second commands for adjusting the power levels of the first and second signals to the first and second base stations, respectively. The power level control commands are transmitted from the remote station to the base stations less frequently during macrodiversity to reduce the signalling requirements between the controller and the base stations. Also, the step size of the adjustment of the power levels of the first and second signals by the controller is reduced during macrodiversity to reduce the signalling requirements. This power control method is particularly beneficial for a CDMA system.
