Abstract

The invention discloses an enhancement type load balancing method based on adjacent region load information, which mainly solves the problem that the throughput of a system is reduced as the call of a user is dropped caused by adjacent region interference when the user is switched in the load balancing. The enhancement type load balancing method is mainly and technically characterized in that an original region can detect the load information of the original region, and trigger the load balancing; the original region can generate a target region list; the original region can calculate priority weights of target regions; the target region list is ranked according to the priority, and a primary termination threshold of the load balancing of each target region is calculated; the original region orderly selects the target regions from the target region list to carry out load transfer; and after the load balancing is finished, the original region waits for the nest load balancing execution cycle. The enhancement type load balancing method can efficiently solve the problem that the call of the user is dropped because of strong interference when the user is switched in the load balancing, thereby enhancing the service quality of the user in the system and the capacity of the system.

Description

technical field

[0001] The present invention relates to the field of wireless communication, in particular to the cell load balancing in the advanced international mobile communication IMT-Advanced system architecture, which can be used in the load balancing process of the source cell, specifically, the load of the adjacent cell is considered when the source cell performs load balancing Information, select the optimal neighbor cell for load balancing. Background technique

[0002] The 3rd Generation Partnership Project 3GPP Long Term Evolution system can provide users with richer multimedia services with its higher bandwidth, but operators are most concerned about obtaining higher profits through effective control of operation and maintenance costs . Therefore, controlling the cost of operation and maintenance in LTE systems will become a very challenging problem. The 3GPP proposes a new operation and maintenance strategy for the long-term evolution system, that is, the lo...

Embodiment Construction

[0022] refer to figure 1 , the scene used in the present invention is an IMT-Advanced system, and the IMT-Advanced system is composed of an evolved packet core network EPC and an evolved access network E-UTRAN, wherein the EPC is composed of a plurality of mobility management entities MME or serving gateways S-GW The E-UTRAN is composed of a plurality of eNBs, the eNBs and the nodes in the EPC are connected to each other through the S1 interface, and the eNBs are connected to each other through the X2 interface.

[0023] refer to figure 2 , the present invention is based on the enhanced load balancing method of adjacent cell load information, and the specific steps are as follows:

[0024] In step 1, the source cell detects its own load information and triggers a load balancing process.

[0025] 1a) During the load balancing execution cycle, the source cell detects its own load information, if the load value of the source cell is greater than the heavy load threshold ρ′, th...
