Abstract
The present invention provides a method and an apparatus for responding to changes in measurement of a system load in a spread spectrum communication system. Using a load control algorithm, for example, the spread spectrum communication system may handle sudden changes or variations, such as spikes or steps in system load measurements for an uplink and/or a downlink between a mobile unit and an access network. The load control algorithm determines whether a sudden variation of a measured system load is generated by a source not under a power control or is caused by a variation of a spread spectrum communication system load. A load control measure may be selectively applied to adjust one or more parameters associated with the system load. That is, an increase of a first new measurement value may be limited to a given maximum increment for one sampling time period of a plurality of sampling time periods in response to a spike in the system load or a desired response to a sudden increase of the system load may be delayed by a given maximum number of measurement samples. By allowing a limited increase, the response of the spread spectrum communication system to sudden changes of a syst…
