Scheduling method of multi service multiplexing supporting medium access control lay

The invention relates to a multi-service integration dispatching method that supports the medium access control layer. The order of priority for system dispatching radio bearer services in each dispatching time unit TTI is as follows: a delay-constrained (GD) service, a minimum guaranteed bandwidth (GB) service and a best effort (BE) service; in the course of dispatching, if resource blocks are not used up when the resource blocks are dispatched to a certain radio bearer, the rest of the resource blocks will be dispatched to other radio bearers in the same UE as the radio bearer; if the rest of the number of resource blocks is zero, the average speed of all radio bearers will be renewed and next dispatching time unit will be entered. The invention avoids the problem that a service of high priority occupies resources of a service of low priority and ensures minimum QOS requirements of two services using definite proportional fair scheduling algorithm specific to GD and GB services.
