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 system load
may be controlled such that some blocking may occur but dropping of calls
may be avoided. In this manner, the load control algorithm may avoid
unnecessary dropping of calls.
