Abstract

The invention discloses an LTE load balancing method based on admission control. The method comprises the following steps: step one, calculating a cell load; step two, performing service measurement; step three, performing resource accounting; and step four, performing the admission control. The method starts from analysis of the cell load, through calculation of the application service success probability of a current service arrival cell, the size of an RB resource block consumed by service is reckoned, determination thresholds are set for two times, when a load after access is smaller than an average load, a nearest access mode is employed, and otherwise, through reckoning, by comparing the system equalization degree caused by access of a minimum load adjacent cell with the system equalization degree of a current access, a corresponding access measure is taken. The method provided by the invention has the advantages of fully utilizing the resource efficiency of a whole system, providing higher cell service throughput and improving client perception.

Description

technical field [0001] The present invention relates to the technical field of LTE communication network, in particular to an admission control-based LTE load balancing method that can effectively solve the congestion problem of hotspot cells and improve system resource utilization. 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. [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 3: Calculate load variation; Step 4: Implement load transfer; Step 5: Convergence judgment...
