Dynamic sorting-based device and base station connection method in cellular flow unloading network

Abstract

The invention discloses a dynamic sorting-based device and base station connection method in a cellular flow unloading network. The method comprises the following steps: (1) multiple APs are deployed near a user for providing service for the user, the user can select to be accessed to an AP or a BS, and a benefit function is given to evaluate current benefits of the user; (2) through calculation, after a problem is layered, once the user access mode is found to be determined, the transmitting power of the user is determined accordingly, the benefit function is only related to the user access condition, and thus, the optimal user access only needs to be found for determining the optical system benefits; and (3) according to restrictive conditions C1 and C2 and in combination with a target function given in the second step, the user access mode is selected to maximize the benefits of the overall system. Superior user access can be quickly and effectively found, the power distribution of the user is determined at the same time, and the efficiency is high.

Description

technical field [0001] The invention relates to a cellular network utilizing dynamic sorting to optimize user access control and power allocation to maximize system revenue. Background technique [0002] In recent years, with the rapid development of mobile devices and mobile network services, huge traffic has been generated in cellular networks. And these unexpected flows will cause great congestion to the cellular network. Especially in some peak hours, the 3G network is overloaded. And mobile users in the overloaded area will experience poor experience, such as lower transmission rate and longer delay. A very intuitive solution is to update the 4G network. Another way is to deploy more small base stations. Obviously, the latter is easier and simpler. It will be a very economical solution to offload the user's traffic to the WiFi network. It has many characteristics: 1) The hardware of the device does not need to be updated; 2) Communication on the unlicensed spectru...
