Research On The Application Of Soft-switch Tecnology Based On McWiLL In Private Network

From the aspects of the network architecture, key technologies and air interface, in-depthsystematic study McWilLL communication system standards. McWiLL system is one of thekey technologies of soft-switch technology which is the quality of service in the privatenetwork to further enhance the bottleneck problem, this paper summarizes the main method tosolve soft-switch QoS and their advantages and disadvantages, throughput, latency and otherindicators analyzes the impact on system performance, try the new agreement COPS protocolfusion followed by the formation of the amendment to the classic SIP protocol and systemperformance simulation in NS platform, the simulation results show that the new agreementcan be an effective solution to the original SIP delay jitter big and throughput constrainedproblems. Provides technical reserves for the further application of soft-switch technology inthe private network.This article first theoretical analysis the McWiLL (multi-carrier Wireless InformationLocal Loop system), it is as an independent research and development, with completelyindependent intellectual property rights of broadband wireless communications technology,wireless is tailor-made for the the industry private network and public networkaccess system.Basic principles and performance of McWiLL further elaborated based McWiLL soft-switchtechnology used SIP protocol soft-switch system can be used in several protocol, call flowcomparison. The established wired+wireless universality model, soft-switch SIP protocolMcWiLL in throughput performance reasons. To analyze the share of advantages in themainstream protocol soft-switch, SIP protocol. Secondly, the theoretical analysis to solve thesoft-switch agreement service quality problems, and departure from the simulation point ofview, the amendment a way to improve the quality of service of the soft-switch COPS-SIPprotocol, the revised protocol compared with traditional SIP protocol has better enhance thequality of service capacity.The theoretical analysis of the advantages of using SIP soft-switch communicationsystem based on McWiLL and throughput of the network the NS platform for simulation,validation better the soft-switch network performance using the SIP protocol. Secondly, thequality of service QoS soft-switch system upgrade problem, verified by simulation theCOPS-SIP corrected agreement can be an effective solution to the long network latency and jitter range, the premise does not reduce the transmission of packet loss rate, improve networkthroughput capacity, and provides a new idea to improve the quality of voice, video,multimedia, and other communications services.
