In a cellular network, several traffic control services are previously provided. Above all, when the network becomes congested e.g. world-cup ticket-reservation, THREE traffic control scenarios are proposed. In this paper, applying an AHP (Analytic Hierarchy Process) approach enables us to obtain a solution which scenario is best/worst among these traffic control scenarios, from user's view point. Firstly, we construct a web site on which cellular network users can simply answer a questionnaire regarding grade of traffic services via internet. We then formulate a pair-wise comparison matrix (p.c.m.) through this questionnaire result for an individual respondent. We next calculate the maximum eigenvalue of the p.c.m., which leads to CI (consistency index). Via this CI value, we can see how well the respondent answers logically. Through this process, we obtain all CI values for all questionnaire respondents. We propose a decision making technique for questionnaire respondents group through these individual CI values. Taking the geometric mean of p.c.m. elements we obtain the weighted eigenvector for the maximum eigenvalue of this geometric mean p.c.m., namely priority (users' dissatisfaction) vector. From the priority vector, we can see how well/badly these traffic control scenarios operate.
