Non-cooperation game resource allocating-based 3G (the third generation telecommunication) / WLAN (wireless local area network) heterogeneous network accessing control method

A non-cooperation game resource allocating-based 3G (the third generation telecommunication) / WLAN (wireless local area network) heterogeneous network accessing control method belongs to the technology of a wireless heterogeneous network, and solves the problems such as low network effectiveness, unbalanced resource allocation in each area and low resource utilization rate in the existing heterogeneous network resource allocating and accessing control. The method comprises the steps of establishing a 3G/WLAN non-cooperation game model to obtain an effectiveness expression of the WCDMA (wideband code division multiple access), the TD-SCDMA (time division-synchronization code division multiple access) and the CDMA (code division multiple access) 2000, solving the non-cooperation game Nash equilibrium solution of the three networks as the optimal time solution of the total network effectiveness in the whole service area and proving the uniqueness of the Nash equilibrium. The bandwidth in each covering range is obtained according to the allocating result of the CDMA, TD-SCDMA and the CDMA2000 network game sources, the rest bandwidths of the WCDMA, TD-SCDMA, the CDMA2000 and the WLAN network are computed, the accessing of a new user and the switching of the user in the network are judged and the method is suitable for the field of the wireless heterogeneous network.
