Realize the function of Wireless network congestion state aware.
Wherein, range is reported to refer to which cell needs reports.
Reporting schemes e.g. periodically report, or produce congestion and just report.If it is periodically reporting, then periodically
Report network state, including congestion and non-congestion；It just being reported if it is congestion is produced, then the network state reported is congestion,
Such as congestion mark is set to 1.
It is, for example, at least one of following for reporting parameter:
Wireless parameter: physical radio resource block (PRB) call ratio, online user number, the average resource of every user occupy,
Average bandwidth etc.；
Load of base station parameter: base station CPU occupation proportion, base station buffer occupation proportion；
S1 interface parameters: packet loss, signaling delay, Forwarding Delay of S1 interface etc.；
Traffic measurement parameter: cutting off rate, percent of call completed etc.；
That is, when at least one above parameter is more than threshold value, it is believed that congestion occurs for network.
