Problems solved by technology

The disadvantage is that because this method needs to calculate the average load of the neighbor set frequently, it will increase the system load additionally, resulting in a lag in customer perception
In addition, there is only one parameter for evaluating the load of the community, which does not have flexibility and flexibility, and has certain limitations

Abstract

The invention discloses an LTE load balancing method based on critical triggering. The LTE load balancing method based on critical triggering comprises the following steps that 1, a cell load is calculated; 2, a critical triggering point is established; 3, first critical triggering is conducted; 4, second critical triggering is conducted; 5, convergence judgment is conducted. According to the LTE load balancing method based on critical triggering, the cell load is analyzed firstly, corresponding load variation is calculated by establishing the critical trigger point and checking a first critical triggering threshold value and a second critical triggering threshold value, and a corresponding number of user transfer decisions are made by means of the capacity of a physical resource block and the balancing factor requirement. By the adoption of the LTE load balancing method, the resource utilization rate of a whole communication system can be increased, higher cell service throughput capacity can be achieved, and customer perception is improved.

Description

technical field [0001] The invention relates to a method for load balancing of cells in an LTE communication network, in particular to a load balancing method based on criticality triggering. Background technique [0002] In cellular mobile communication, the arrival rate of users and the types of transmission services are randomly changed, that is, unbalanced, which leads to service requests in hotspot cells being much higher than an acceptable level, while other cells are There are still available resources to serve more users. Load balancing can solve the congestion problem of hotspot cells, improve system resource utilization, and provide services with guaranteed QoS (Quality of Service) for more users. [0003] 2014.12.10 disclosed a Chinese patent application number CN201410324613.0 based on a neighbor set based LTE load balancing method, the method includes the following steps: step 1: calculate the global load; step 2: build the minimum load set of neighbors; step ...
