If two carrier waves all have the formation buffer memory not touch the single carrier terminal at the end, then change step 408;
If two carrier waves all do not have the formation buffer memory not touch the single carrier terminal at the end, then adopt the RR mode to select a carrier wave to dispatch.
It promptly is that read less than data in the buffer queue of this terminal the base station that the formation buffer memory touches the end, illustrates that this terminal data amount is very little; And that the formation buffer memory does not touch the data that the end just illustrates that this terminal need transmit is bigger.
Step 407: the carrier wave of selecting not have the formation buffer memory not touch the single carrier terminal at the end carries out the scheduling of this terminal.
Step 408: whether the formation buffer memory of judging two carrier waves does not touch the single carrier terminal at the end has formation speed to be higher than the formation that guarantees bit rate;
If a carrier wave has, then change step 409;
If two carrier waves all do not have, then change step 410;
All there is not formation speed to be higher than the formation that guarantees bit rate if the formation buffer memory of two carrier waves does not touch the single carrier terminal at the end, then adopts the RR mode to select a carrier wave to dispatch.
Usually, each terminal has a plurality of formations, can be to a plurality of business that should terminal, and each formation has one to guarantee bit rate, and promptly professional minimum requirements to transmission rate is not less than 100kbps such as the speed of high-speed downloads business.
Step 409: the carrier wave of selecting to have formation speed to be higher than the single carrier terminal of the formation that guarantees bit rate carries out the scheduling of this multi-carrier terminal.
Step 410: obtain the terminal satisfaction that this formation of previous moment in two carrier waves has obtained the highest single carrier terminal of speed respectively.
The concrete account form of terminal satisfaction such as step 302 are described.
Step 411: whether the terminal satisfaction of judging two single carrier terminals differs less than the satisfaction threshold value;
Then change step 413 less than the satisfaction threshold value, then change step 412 more than or equal to the satisfaction threshold value.
If, then changeing step 413 less than the satisfaction threshold value then illustrate that the resource idle condition of these two carrier waves is more or less the same, the satisfaction difference of two single carrier terminals selects a carrier wave arbitrarily.Satisfaction threshold value herein can rule of thumb be provided with actual conditions flexibly.
Step 412: select the carrier wave of terminal satisfaction value minimum to carry out the scheduling of this multi-carrier terminal earlier.
Terminal satisfaction value is more little, and the expression terminal is satisfied more to the quality of service of current acquisition; Select the carrier wave of terminal satisfaction value minimum promptly to select the terminal carrier wave satisfied to the quality of service of current acquisition, just compare other carrier waves, resource carrier wave also relatively more more than needed is dispatched.
Step 413: adopt the RR mode to select a carrier wave to dispatch.
Obviously, selecting certain sub-district to carry out the scheduling of multi-carrier terminal, the idling-resource of this sub-district is used up and resource that this multi-carrier terminal needs when still not enough, returns step 401, continues to select next scheduling to give the multi-carrier district of this multi-carrier terminal.
