Abstract

The invention relates to a method for balancing the moving load of an ultra-dense network and belongs to the technical field of wireless communications. According to the method, a plurality of cells are adopted to balance the load of an overloading cell on the basis of moving load balancing; meanwhile, the method employs load benefit to express a cost in the load balancing process. The Nelder-Mead algorithm is adopted to obtain optimal parameter values, and therefore, the utilization rate of resources between cells can be increased and the system efficiency can be improved while the load is balanced to guarantee the quality of services for users.

Description

technical field [0001] The invention relates to a method for balancing mobile loads in an ultra-dense networking, and belongs to the technical field of wireless communication. Background technique [0002] In recent years, wireless data services have experienced explosive growth, and a large amount of data traffic occurs in indoor environments. Therefore, small base stations (Small Cell Base Stations) are introduced to improve indoor coverage and overall network capacity. In the future 5G communication, the wireless communication network is evolving in the direction of network diversification, broadband, integration and intelligence. With the popularization of various smart terminals, data traffic will experience a blowout growth. In the future, data services will be mainly distributed indoors and in hotspot areas, which makes the ultra-dense network one of the main means to realize the massive traffic demand of 5G in the future. The ultra-dense network can improve network...
