Title: (EN) Method for controlling power in mobile networks
(ZH) 移动网络中的功率控制方法
Abstract: front page image
(EN) The invention relates to a method for controlling power in a mobile network, said method including the following steps, for each server station s, wherein s=1,...A, belonging to a group of A server stations, A>=2, each transmitting at a power Ps(b) , wherein b=1,...,B, in B frequency sub-bands, with B>=1: a) receiving, from mobile terminals served by said server station s, radio parameter measurements taken by said mobile terminals; b) calculating at least one predetermined value formula (AA), where b belongs to [1,...,B], using said measurements; c) transmitting the respective value formula (AA) to at least one other server station t, or to another device associated with said server station t, and receiving the equivalent value formula (BB) from at least said server station t or said associated device; d) calculating derivatives formula (CC), using at least said value formula (BB), where U is a predetermined utility function for said network; and e) updating the transmission powers Ps (b) so as to reduce the value of said utility function U. Said method is characterized in that the utility function formula (DD) is an increasing function of the load formula (EE), where s=1,..., A, defined over a predetermined time period T, for each server station of said group, said load formula (EE) depending on traffic flow volumes arriving in the geographic area D served by the server station s and flow rates provided by said server station, and in that said value formula (BB) is representative of the quantity formula (FF).
