Show, specific appraisal procedure includes:
Step 301: data conversion；It is collected to analysis system in advance when the performance to each base station is assessed
Status data formats, and is converted into format required when assessment.
Step 302: calculation base station load capacity；The corresponding PageRank in each base station is calculated by PageRank algorithm to obtain
Point, further obtain the load capacity of base station.
Wherein PageRank algorithm is as follows:
1) each index value for influencing base station is determined；Base-station node parameter that wherein, index value is got by analysis system,
It is obtained in system environments parameter and network topological information, specifically has which index value that can obtain according to the actual situation；
2) network topology structure of emergency communication network is determined；The network topology structure is acquired by analysis system；

Historical information is added in PageRank algorithm, it is to be understood that historical information is the base-station node ginseng of the history got
Number.
PageRank algorithm basic principle is as follows:
1) in the initial stage: base station builds Web graph by linking relationship, and same PageRank is arranged in each base station
Value, by the calculating of several wheels, can obtain each base station PageRank value finally obtained.With each round calculating into
Row, the current PageRank value in base station can be continuously available update.
2) calculation method of base station PageRank score is updated in a wheel: updating base station PageRank score in a wheel
In calculating, each base station goes out what its current PageRank value was evenly distributed to that this base station includes on chain, in this way each
Link obtains corresponding weight.And each base station will all point at the weight summation for entering chain and being passed to of this base station, just
Available new PageRank score.When each base station obtains updated PageRank value, a wheel has just been finished
PageRank is calculated.
PageRank algorithm basic calculating formula is as follows:
Wherein PR (Pi) it is base station PiPageRank score, C (Pj) it is PjGo out chain number, and PjIt is wrapped for the region to be measured
P is removed in all base stations includediBase station except base station；Q is damped coefficient；N is total number of base.
Assuming that: if a set being made of only 4 base stations: A, B, C and D.If whole base stations all chains to A,
The so PR of A (PageRank) value summation that will be B, C and D.
PR (A)=PR (B)+PR (C)+PR (D)
If continuing B is also linked to C, and D also has 3 base stations being linked to comprising A.One base station cannot vote 2
It is secondary.So B gives each base station half fare, with identical logic, ticket that D is launched only has three/in one arrived A's
On PageRank.
In other words, go out the PR value that sum divides a base station equally according to chain.
Because being 0 there are some base station chaining numbers, no matter that is, those base stations for not linking what other base station,
Referred to as isolated base station, enables very more base stations to be asked by imitative.Therefore PageRank formula need be modified, i.e., simple
The general value q=0.85 of damped coefficient (damping factor) q, q is added on the basis of formula.Its meaning is, random
Moment, user reach behind certain base station and continue the probability transmitted backward.
Step 303: assessment load of base station ability；Base station can be evaluated according to the corresponding PageRank score in each base station
Load capacity, PageRank score is higher, and the load for proving that base station is current is bigger, and load capacity is lower.
Step 304: releasing overload base station；Preset threshold is set according to historical data, by the corresponding of each base station
PageRank score is compared with preset threshold, if the PageRank score of some base station is greater than preset threshold, illustrates this
Base station is overload base station.
Step 305: overload base station early warning；It alarms overload base station.
