1. the method being used for providing Stochastic accessing to radio communications system (1000), described radio communications system provides the service with different service quality demand to multiple subscriber equipmenies (10) of the resource sharing described radio communications system (1000), described method include at least one for service request to distribute the step of the resource of described radio communications system (1000), the step of described Resources allocation includes the step dividing resources at least two resource group, different resource groups is dedicated to different types of service, the performance of random access procedure is wherein set by the size increasing or reducing the resource group being exclusively used in service quality according to required collision probability,Wherein the collision probability for a time slot is expressed as followsin:

  • And,Wherein γ

    is the average that asynchronous RACH (RACH) per second is attempted, NTIt is timeslot number per second, NFIt is every slot frequency block number, and NsignIt it is targeting sequencing number.
