Abstract
A practical and efficient persistency control for the Universal Mobile Telecommunications System, comprising determining a persistency value for making random transmissions for access to the system, the method comprising:1. determining for a system cell, the maximum allowable user equipment transmission power PMAX;2. assessing the number in a current time interval of ongoing packet transmissions NCURRENT based upon a fraction &agr; of user equipment measured current transmission power Ptotal;3. assessing the power available in a next time interval based upon the maximum allowable transmission power and the current transmission power, and determining therefrom a number of allowable new packets NNEXT in the next time interval; and4. determining a persistency value p for transmission to user equipment in said cell, being a function of the number of ongoing packet transmissions NCURRENT and the number of allowable new packets NNEXT.
