Abstract: A system, method, and apparatus for the efficient allocation of dedicated and/or shared downlink communication channels for packet data users in a communication system. The present invention provides a switching scheme in which users which are close to a base station are allocated a downlink shared channel in order to save channelization codes in the system, whereas users that are far from a base station are allocated a downlink dedicated channel in order to conserve transmission power.

Abstract: Downlink congestion is accurately detected and congestion control is more effectively provided without decreasing the system downlink capacity. The characteristics of the downlink transmission of the base station are monitored and used to selectively adjust a fast congestion control (FCC) alarm threshold value in each base station. A FCC relief action is initiated upon detecting the downlink power exceeding the FCC alarm threshold value, i.e., potential downlink congestion. The FCC relief action includes temporarily blocking data services in the system or rapidly decreasing the downlink transmit power of the packet data user's Dedicated Physical Channels in the base stations.

Abstract: A method and system that enables the changing of the gain in a closed loop (e.g., self-configuring) telecommunications system based on the age of the available measurements. A high gain is used when measured data are “fresh”, so as to obtain a good performance (e.g., a fast response) for the telecommunications system. The gain is then reduced when the age of the measurements increases. The decreased gain results in a slower system response, but this is a desirable result in order to preserve stability. The system and method may be applied, for example, in many mobile telecommunications systems (e.g., GSM, WCDMA, etc.). In one embodiment, the system and method of the present invention modify the closed loop gain in an adaptive fashion and use one or more fuzzy membership functions for specifying what is meant by “fresh” measurements.
