Abstract

The invention discloses an LTE load balancing method based on a neighbor cell set. The method includes the following steps: step 1: calculate the global load; step 2: construct the minimum load adjacent cell set; step 3: calculate the load variation; step 4: implement load transfer; step 5: converge judgment. The LTE load balancing method based on the neighbor cell set obtained in the present invention starts with analyzing the load of the cell, calculates the corresponding load variation according to the difference between it and the global load, and implements the corresponding Number of user transfer decisions. After the method is implemented, the resource utilization rate of the entire communication system can be utilized to provide higher cell service throughput and improve customer perception.

Description

technical field [0001] The invention relates to a method for load balancing of cells in an LTE communication network, in particular to a method for balancing loads based on adjacent cell sets. 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. For this reason, the present invention designs a cell load balancing method based on the set of neighboring cells, through targeted analysis of the load of the target cell, load transfer with surrounding neighboring cells, and then achieves the goal of adjusting the loa...
