| Along with telecommunication industry reform thoroughly, China Network Communication Group further speeds up in the Y city wireless voice communication service development, First has promoted the SCDMA wireless public communication service, And by its outstanding performance and flexible service policy, Y city branch has opened up the market perspective rapidly, and has won the good prestige in the Y city telecommunication market.But as the network expansion and user quantity sharply increase, the outage probability becomes the bottleneck for the Y city branch to promotion the grade of service gradually. In order to solve the outage probability to be high, and reach the standard outage probability of the wireless network, a campaign was originated by the Y city branch, which was held to optimize the SCDMA network outage probability. And has achieved the outage probability control goal in the active stage, The local network outage probability dropped down to about l%,It had surmounted the wireless network 2% outage probability target, Improved the SCDMA network grade of service largely, and has provided the powerful support for the service development.This article regard the SCDMA network outage probability optimization in Y city branch as the background, we launched the research on the outage probability mechanism to the SCDMA network, and network present situation as well as the SCDMA equipment performance, radio propagation characteristic and so on, then implemented the network optimization campaign to the outage probability of the SCDMA network. Finally it fell down from original 2.15% to 1%. That has surpassed the correspondence wireless communication network outage probability target which request 2%, it enhanced the SCDMA network for the Y city branch to promote quality of service, and made the network economic efficiency as well. |
