Method and apparatus for load balancing configuration among base stations, and wireless network system

Abstract

The invention provides a method and apparatus for load balancing configuration among base stations, and a wireless network system, and relates to the technical field of wireless networks. The method comprises the following steps: configuring the same load assessment algorithm to a source base station and a target base station; obtaining load assessment results of wireless resource states owned and accessed by the source base station and the target base station according to the load assessment algorithm; and according to the load assessment results of the source base station and the target base station, determining that the source base station initiates a base station switching process. By using the method, apparatus and the wireless network system, provided by the invention, unified standards are configured for the load assessment algorithm so that load balancing configuration among base stations especially among the base stations of different manufacturers can be accurately finished.

Description

technical field [0001] The invention relates to the technical field of wireless networks, and provides a load balancing configuration method and device between base stations and a wireless network system. Background technique [0002] Load balancing between base stations usually includes three technical points: load evaluation of source base station and target base station, load information interaction, and user migration. Such as figure 1 As shown, the definition of the specific process is as follows: [0003] 1. Load evaluation: It means that the base station needs to calculate and evaluate the utilization rate of wireless resources to determine its own load; [0004] 2. Load information interaction: the source base station sends a RESOURCE STATUS REQUEST (resource status request) to the target base station, including the source base station Measurement ID (measurement report ID), reporting period, feature report, etc.; the target base station sends a RESOURCE STATUS RES...

Problems solved by technology

[0006] In the existing technology, for the above-mentioned load evaluation, if it is only calculated according to the radio resource usage rate defined in 3GPP 36.314, the value obtained by this calculation method only reflects the real PRB (Physical Resource Block) usage status, but the result will be Affected by the error caused by the base station allocating too many resources for Non-GBR (non-guaranteed speed), it cannot truly reflect the load of the base station, especially: the load evaluation standards of the source base station and the target base station are inconsistent (such as the source base station and the target base station Devices belonging to different manufacturers), will bring more problems of user migration failure and unbalanced network load;

[0007] For the above load information interaction, the load information interaction includes many cells. Except for the clear definition in the Radio Resource Status (wireless resource status) 3GPP standard, the rest of the cell protocols only give the value range without a clear definition or Algorithm requirements are inconsistent with each manufacturer’s implementation; especially if the information elements in the load information interaction between the source base station and the target base station may be inconsistent with each other (for example, the source base station and the target base station belong to two different manufacturers’ equipment), it will cause subsequent user migration failures , The problem of network load imbalance;

[0008] For the above user selection and migration, if the handover criteria or threshold of the source base station is inconsistent with the acceptance criteria or threshold of the target base station during the migration process of the user between two base stations, it will cause too many handover failures and affect the network evaluation index
