Abstract

In this paper, we propose a game theoretic channel sharing model that allocates resources of a base station between MNO(Mobile Network Operator) and MVNO(Mobile Virtual Network Operator) in a fair and efficient manner. Considering the input traffic loads of MNO and MVNO, the proposed model uses the bargaining game theory to allocate channel resources between MNO and MNVO. When the input loads of the carriers are asymmetric, the proposed model increases the resource utilization by allocating more channel resources to the operator with high input load. In addition, the proposed model prevents the quality of service of an operator from degrading even if the input load of the other operators increases excessively.

본 논문에서는 기지국 채널 자원을 MNO(Mobile Network Operator)와 MVNO(Mobile Virtual Network Operator)가 공유할 경우 사업자들에게 채널 자원을 공정하고 효율적으로 할당하기 위한 게임 이론적 모델을 제안한다. 제안 모델은 협상(Bargaining) 게임 이론을 이용하며 MNO와 MVNO의 입력 부하를 고려하여 이들 사이의 기지국 채널 자원을 할당한다. 제안 기법은 사업자별 입력 부하가 비대칭적인 경우 입력 부하가 낮은 사업자보다 입력 부하가 높은 사업자에게 보다 많은 양의 채널을 할당하여 기지국의 채널 이용율을 증가시키며 또한 한 사업자의 과도한 입력 부하로 인해 타 사업자의 서비스 품질이 저하되는 것을 방지한다.
