Patent ID: 7336629

Claim:
A method comprising: controlling a power used for transmitting data between a terminal device and a transceiver device of a communication system; monitoring during each of predetermined time units the power used in a transmission between said terminal device and said transceiver device; requesting an increase or a decrease of the power used in the transmission by using a specific information element for each of the predetermined time units, the specific information element having either a positive value for increasing power or a negative value for decreasing power; storing, during a predetermined period comprising a plurality of subsequent time units, a plurality of the values of the specific information elements; calculating a power raise requested for the power used in the transmission by summing the stored values of the plurality of specific information elements; calculating an average received power of transmission during the predetermined period comprising the plurality of subsequent time units by using the stored values of the specific information elements; determining whether or not the calculated power raise is greater than a sum of the calculated average power of transmission and a predetermined level; and if the determination is positive, inhibiting an increase of the power used in the transmission even if an increase is requested, and if the determination is negative, allowing an increase of the power used in the transmission when an increase is requested.
