Abstract:
A method of handling user plane data in a packet switched network. A packet inspection node determines a compression ratio and/or content information for the user plane data, and sends said compression ratio and/or content information towards a user plane data handling node. The user plane data handling node receives the compression ratio and/or content information, and handles the user plane data in dependence upon the compression ratio and/or content information.
Abstract:
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.
Abstract:
A method and apparatus for handling data compression in a mobile communications network. As a result of mobility of a mobile endpoint such as a mobile terminal, a first network node receives compression information relating to a remote node. The compression information is selected from any of compression capabilities of the remote node, a type of compression available at the remote node and an identity of the remote node. The received compression information is used to perform a compression operation on first data to produce modified data. The modified data is then sent towards the remote node.
Abstract:
A radiocommunication system balances interference reduced by soft handoff with access network loading increased by soft handoff. When the access network loading exceeds some threshold for a particular transmissiom source, then the system limits or reduces that source's soft handoff connections with remote stations.
Abstract:
The transmit power of a base station transmission to a mobile station is advantageously controlled. The base station receives a signal from the mobile station and determines a signal-to-interference ratio (SIR) associated with the received signal. The base station controls its transmit power to the mobile station using the determined SIR value in conjunction with a transmit power control command received from the mobile station. When the mobile station is in the process of a soft handover involving two or more base stations, each of those base stations determines an SIR value associated with a signal received from the mobile station. Moreover, each of the base stations controls its respective power using both the power control command received from the mobile station and the SIR determined by that base station. Similarly, when the mobile station is in the process of softer handover involving two or more sectors of a single base station, the SIR associated with a signal received from the mobile station in each of those base station sectors is determined and used to control the respective power of each base station sector in conjunction with a power control command received from the mobile station.

Abstract:
A radiocommunication system balances interference reduced by soft handoff with access network loading increased by soft handoff. When the access network loading exceeds some threshold for a particular transmission source, then the system limits or reduces that source's soft handoff connections with remote stations.
