Problems solved by technology
However, some load balancing methods in the prior art only aim to reduce the load of high-load cells to a specific threshold. Although the number of cells affected during the execution process is small and the mechanism is simple, the current theoretical research aims to improve the load of each cell in the network. The load balancing degree of the cell is the goal, and it is bound to reduce the load of the high-load cell. However, because this method needs to improve the load balancing degree of the entire network, the balancing effect is good, but because it needs to involve all cells in the network, the execution efficiency is low

The invention relates to a system and a method for load balance of a mobile communication network. The method includes: monitoring loads of cells in the network; when the load of a certain cell is larger than a trigger threshold, selecting a load balance area, marking a switchable terminal, marking a switching group, generating an adjacent map according to adjacency relation of the cells, and setting a peak weight and a side weight of the adjacent map according to terminal loads; setting an equation by taking an adjacent map partition mode as an independent variable, taking minimization of weight difference of all parts of the partitioned adjacent map as a primary target and taking minimization of quantity of switching execution terminals as a secondary target; working out an optimal solution of the equation; obtaining user terminals, needed to be switched to the adjacent cell, in each cell in the balance area according to the optimal solution and an initial solution of the equation. Due to the fact that the target of the set equation is equivalent to minimization of load difference of the cells, the acquired optimal solution enables highest load balance of selected areas, network load balance solution is optimized, and failure in treatment of gathering of a great quantity of high-load cells is avoided.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a load balancing method of a mobile communication network and a load balancing system of a mobile communication network. Background technique [0002] With the rapid increase of users' demand for mobile access, the LTE mobile communication system has the characteristics of dense distribution of access network cells, which improves the user capacity per unit area and also improves the signal strength per unit area. However, limited by physical resources, the number of users that a cell can accommodate is still limited. In addition, due to the dense distribution of mobile users in cities, the current LTE system may experience high loads in multiple adjacent cells at the same time. [0003] Some load balancing methods in the prior art often only consider the general situation of high load of a single or a small number of base stations, while ignoring the new characteristics o...
