Abstract

The invention relates to the field of mobile communication, in particular to an ultra-dense networking-oriented load balancing method and system. The ultra-dense networking comprises a plurality of wireless access points and is used for accessing network users. The method comprises the following steps: constructing a cost objective function (shown in the description) of the wireless access points;constructing a network user dynamic change differential equation dx (t) = f (x (t), li (t), i = 1... K) dt, the li (t) being the load capacity of the ith wireless access point at the moment t, the x(t) being a network user dynamic change state, and the k being the number of the wireless access points in the ultra-dense networking; and forming a differential game model by the cost objective function of the wireless access point and the network user dynamic change differential equation, solving the differential game model to obtain a Nash equilibrium solution, and taking the Nash equilibrium solution as an optimal load distribution value of the wireless access point. According to the invention, the load balancing problem of users among different cells can be solved, and reasonable load distribution in an ultra-dense networking network is realized.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a load balancing method and system for ultra-dense networking. Background technique [0002] In the future mobile communication system, it is necessary to provide greater mobile data traffic and bandwidth to meet the ever-increasing service demand. In order to achieve the above purpose, a key technology is to obtain higher spectrum efficiency and spectrum reuse rate by reducing the coverage area of ​​the cell. In addition, by introducing small base stations, user coverage within the coverage area can be improved. Therefore, ultra-dense networking technology is proposed to increase system capacity and meet the above requirements. [0003] RoF (Radio over Fiber, wireless communication over light) technology, which combines optical communication and wireless communication technology, can be used as a small base station and applied to the next generation mobile communication sys...
