Method and device for mobile load balancing and air interface resource utilization statistics

Abstract

The invention discloses a mobile load balancing, air interface resource utilization rate counting method and a device; the method comprises the following steps: a target base station uses a QoS request corresponding to a data flow to count an air interface resource usage condition in classification; the target base station generates community wireless load information containing the air interface resource usage condition; the target base station sends the community wireless load information to a source base station; the source base station executes the mobile load balancing according to the community wireless load information. The target base station can count the air interface resource usage condition in classification according to the QoS request corresponding to the data flow, and the air interface resource usage condition is sent to the source base station; the source base station uses the QoS air interface resource usage condition corresponding to the data flow so as to execute the mobile load balancing; the community with more business occupy resources of low priority and / or more business occupy resources allowing to be taken is preferably selected to be the target community being load balanced, thereby improving load balancing efficiency, and reducing user experience influence caused by the load balancing process.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for mobile load balancing and air interface resource utilization statistics. Background technique [0002] PRB (Physical Resource Block, physical resource block) is the minimum granularity for resource allocation in the LTE (Long Term Evolution, long-term evolution) system. A PRB corresponds to a time-frequency resource block with a time length of 1ms and a frequency bandwidth of 180kHz. GBR (Guaranteed Bit Rate, Guaranteed Bit Rate) service refers to a type of service that the network needs to reserve resources to ensure a specified service rate. NGBR (Non Guaranteed Bit Rate, non-guaranteed bit rate) service refers to a type of service for which the network does not need to reserve resources and does not promise a service rate. The service transmission is scheduled; if the network has no resources, the service transmission is not scheduled. [0003]...

Problems solved by technology

[0011] In the above example, a large amount of resources in Cell B are assigned to services that can be preempted (that is, the FTP service. The reason why the FTP service can be preempted is that when the bandwidth allocated for the FTP service decreases, the user download rate decreases, but Usually, it will not have a great impact on user experience. When system resources are limited and there are high-priority new services to be accessed, the network will use the method of slowing down the FTP service to release some resources and accept new services), and the Cell A large number of resources in A are allocated to services that cannot be preempted (that is, video services. The reason why video services cannot be preempted is that when the bandwidth allocated for video services decreases, the download rate of users decreases, which may cause interruption of video services ( data buffering), which usually has a great impact on user experience. When system resources are limited, the network usually reduces the resources that can be preempted to accept new high-priority services); in summary, although The air interface resource occupancy rate of Cell B is slightly higher than that of Cell A, but from the perspective of ensuring overall system performance and user experience, Cell B may be a better target cell for load transfer
