Detailed description of the invention
In general, it is achieved the operation that communication flows controls mainly may comprise steps of:
The source base station of step A. terminal understands the actual state of current ink channel to target BS, can be described as link information；
The each target BS of step B. feeds back current link information to source base station；
Step C. source base station, according to the target BS link information received, calculates the relevant informations such as each target BS handling capacity being sent to terminal, then feeds back to each target BS；The handling capacity calculated can be referred to as target throughput.
The each target BS of step D. is according to the handling capacity received, the handling capacity being suitable for when being controlled with terminal communication by scheduler.
In above-mentioned steps C, source base station calculates the method for target throughput of each target BS may be had multiple, and the process of described calculating can depend on other parameter in the dispatching algorithm of the scheduler of source base station or actual application scenarios.
Such as: assume that terminal currently has n link, Tt is expressed as the total throughout that terminal provides, T [i] represents the active link handling capacity at community [i], Tc [i] represents the average link capacities of community [i], this average link capacities can be calculated by average DRC (DataRateControl, the data rate control) value in the period.So, T [i]/Tc [i] means that the scheduling effective percentage at community [i], or represents the load corresponding to community [i].Tt [i] is the Target Link handling capacity at community [i], is used for representing the top limit obtaining handling capacity at community [i] according to the fair algorithm of Target cell, can be calculated as follows:
Tt [i]=Tt* (T [i]/Tc [i])/(T [1]/Tc [1]+T [2]/Tc [2]+... .+T [n]/Tc [n]).
