(3) if the VoIP traffic carrying capacity accounts for 70% of system's total traffic; Then wherein two scheduling of forming carrier wave will adopt RR dispatching algorithm scheduling VoIP professional; The PF dispatching algorithm is then adopted in a remaining scheduling of forming carrier wave; Referring to Fig. 5: form carrier wave 1 and form carrier wave 2 and adopt RR dispatching algorithm scheduling VoIPs professional, satisfy the professional real-time requirement of VoIP, improve user's experience; Form carrier wave 3 and adopt PF dispatching algorithm scheduling common data services, because general data service is not very sensitive to time delay, thus adopt the PF dispatching algorithm to dispatch the throughput that can provide bigger, thus the performance of system improved.
Above-mentioned different with VoIP business shared ratio in system's total traffic; And adopt different composition carrier waves to carry out transfer of data; Wherein in different composition carrier waves, adopt different dispatching algorithms again, make the scheduling of unlimited resources can satisfy the professional real-time requirement of VoIP, the system that makes again has the high throughput of ratio; Both strengthen user's experience, improved the performance of system again.
Wherein, the embodiment of the invention is applicable to that also VoIP business shared ratio in system's total traffic is other any worth situation, and the user can choose dispatching algorithm flexibly according to actual conditions, but processing procedure is similar with above-mentioned three kinds of situation, repeats no more.In addition; Other real-time data services for relatively more responsive to time delay also can adopt above-mentioned processing procedure, and real-time data service and common data services are separated; According to the different composition carrier wave numbers of selecting transmission of the shared ratio of real-time data service; Simultaneously the professional composition carrier wave of transmitting real-time data is adopted to be fit to this professional dispatching algorithm, method is similar, repeats no more.
