This class implements a Migration-based Quality of Service uplink scheduler(MBQoS).
This uplink scheduler uses three queues, the low priority queue, the intermediate queue and the high priority queue. The scheduler serves the requests in strict priority order from the high priority queue to the low priority queue. The low priority queue stores the bandwidth requests of the BE service flow. The intermediate queue holds bandwidth requests sent by rtPS and by nrtPS connections. rtPS and nrtPS requests can migrate to the high priority queue to guarantee that their QoS requirements are met. Besides the requests migrated from the intermediate queue, the high priority queue stores periodic grants and unicast request opportunities that must be scheduled in the following frame. To guarantee the maximum delay requirement, the BS assigns a deadline to each rtPS bandwidth request in the intermediate queue. The minimum bandwidth requirement of both rtPS and nrtPS connections is guaranteed over a window of duration T .

Check deadline from jobs. Migrate requests if necessary.
availableSymbols | available symbols in the uplink frame |
This method verifies for each rtPS request whether it should be migrated to the high priority queue or not. The conditions for migration are: request deadline expires in the frame following the next one, and the amount of bandwidth requested is less than or equal to the amount of available bytes in the next uplink frame.

This method first calculate a priority value for each request in the intermediate queue. Then, sorts the intermediate queue according to the priority values. Finally, while there is available bandwidth, the scheduler migrate the requests to the high priority queue.
