205, judge whether the whole access probability is more than preset second threshold；
The period access probability is less than or equal to the first threshold, then judges that the whole access probability is at this time
It is no to be more than preset second threshold.If the entirety access probability is more than the second threshold, 206 are thened follow the steps；If described
Whole access probability is less than or equal to the second threshold, thens follow the steps 207.
206, the mobile route information is determined as the target mobile route information, by the mobile route information
Access probability is determined as the whole access probability；
The entirety access probability is more than the second threshold, illustrates that the corresponding mobile route of the mobile route information exists
The probability being accessed under complete period is larger, therefore the mobile route information is determined as the target mobile route and is believed
Breath, while setting the access probability of the target mobile route information to the whole access probability.
207, the mobile route information is determined as non-targeted mobile route information；
If the entirety access probability is less than or equal to the second threshold, illustrate that the mobile route information is corresponding
The accessed probability of mobile route is smaller, therefore the mobile route information is determined as non-targeted mobile route information.
For above-mentioned steps 203 to 207, now table 2 is utilized to illustrate.For the period T in table 21, first determine whether certain
The period access probability P (path of a mobile route ii|T1) whether it is more than preset first threshold, if (the paths Pi|T1) be more than in advance
If first threshold, then by period T1Under mobile route i be determined as target mobile route, while by mobile route i in T1Under
Access probability be set as the first probability；If (the paths Pi|T1) be less than or equal to the first threshold, then then judge mobile road
Whole access probability, that is, (paths P of diameter ii) whether it is more than preset second threshold；If (the paths Pi) it is more than the second threshold,
Mobile route i is then determined as target mobile route, while setting the access probability of mobile route i to the (paths Pi)；If P
(pathi) be less than or equal to the second threshold, then mobile route i is determined as non-targeted mobile route.According to above-mentioned side
Method judges period T1Under all mobile routes whether be target mobile route and then using identical method judge when
Between section T2To TnUnder all mobile routes whether be target mobile route.Above-mentioned first threshold and second threshold can basis
Experiment simulation determines most suitable size, is generally chosen between 0.3 to 0.9.If first threshold and second threshold choosing value are excessively high,
Important target mobile route may then be omitted；If first threshold and second threshold choosing value it is too low, may by access probability compared with
Low non-targeted mobile route misjudgement is target mobile route.

In not comprising target mobile route information, then the influence of the local mobility model will not be considered when carrying out bandwidth reservation.By
In the target mobile route information include sequentially connected Base Station Identification, connect base station time and disconnect base station when
Between, therefore the mobile terminal user can be calculated according to these information and cut between each base station in the communication zone
The switching time point changed.
209, each base station is determined according to access probability of the target mobile route information under the switching time point
Reserved bandwidth is needed under the switching time point；
Visit of the target mobile route information under each designated time period is determined in step 204 and step 206
It asks probability, and first determines whether which designated time period the switching time point belongs in step 209, it then can be specified according to this
Access probability under period determines that each base station needs reserved bandwidth under the switching time point.If for example, some mesh
It is larger to mark access probability of the mobile route information under the switching time point, then can by the target mobile route information with
The reserved bandwidth of the corresponding base station of switching time point is arranged more greatly.In conjunction with all target mobile route information in the switching
Access probability under time point, you can the load variations of each base station under switching time point described in preresearch estimates, to rationally true
Fixed each base station needs reserved bandwidth.
210, the total bandwidth according to each base station under the switching time point, accounted for by user under the switching time point
Bandwidth and reserved bandwidth calculation is needed to obtain each base under the switching time point under the switching time point
The available bandwidth stood.
It is total under the switching time point to be equal to each base station for the available bandwidth of each base station under the switching time point
Bandwidth subtracts by the bandwidth of user occupancy under the switching time point and needs reserved bandwidth under the switching time point.
Wherein, design phase of total bandwidth of each base station under the switching time point in base station predefines；In the switching
Between put under obtained by the bandwidth estimation that the bandwidth of user occupancy can be used by current time；It is needed under the switching time point
Reserved bandwidth is obtained by step 209.
Further, after step 210, can also include：
When any base station in the communication zone gets new real-time calls access request, if described in current time
The available bandwidth of any base station is less than the bandwidth needed for the real-time calls access request, then will access the non-of any base station
