The invention relates to a user access center distribution method for a distant active-active telephone traffic platform. The method comprises the following steps: building a telephone traffic qualityentropy function H(P) according to the distance between a current user and each center; building a center balance degree function CV(L) according to a current load of each center; constructing a system balance degree function according to the built telephone traffic quality entropy function and the center balance degree function; solving a user access scheme with the maximum system balance degreethrough the linear programming; selecting the user access scheme with the maximum system balance degree to complete the building of an access network. According to the invention, compared with the prior art, the method is advantageous in that a telephone traffic center distribution method gives full consideration to the service balance of a user side and the load balance of each telephone trafficcenter, and enabling each center to have the better balance.
