1、XX公司GSM網(wǎng)絡(luò)雙頻網(wǎng)專(zhuān)項(xiàng)優(yōu)化總結(jié)報(bào)告一、概述1、雙頻網(wǎng)優(yōu)化目的均衡雙頻網(wǎng)話務(wù)，充分發(fā)揮1800M的話務(wù)吸收能力，降低900M基站頻點(diǎn)復(fù)用度，降低網(wǎng)內(nèi)頻率干擾，提升用戶語(yǔ)音質(zhì)量，改善用戶感知，開(kāi)展雙頻網(wǎng)優(yōu)化工作。2、雙頻網(wǎng)優(yōu)化范圍主要針對(duì)900M和1800M共站小區(qū)進(jìn)行雙頻網(wǎng)話務(wù)評(píng)估調(diào)整。3、雙頻網(wǎng)優(yōu)化標(biāo)準(zhǔn)對(duì)共站的1800M小區(qū)話務(wù)占比低于50%的站點(diǎn)進(jìn)行調(diào)整，增強(qiáng)1800M站點(diǎn)的話務(wù)吸收能力，提高用戶感知。4、雙頻網(wǎng)優(yōu)化成果：通過(guò)本次調(diào)整，調(diào)整前1800M話務(wù)占比為31.56%，調(diào)整后1800M話務(wù)占比為39.37%，
2、整體提升了7.81%；上行語(yǔ)音質(zhì)量(涉及雙頻網(wǎng)優(yōu)化基站)由99.14%上升至99.37%，下行語(yǔ)音質(zhì)量(涉及雙頻網(wǎng)優(yōu)化基站)由99.32%上升至99.59%。二、雙頻網(wǎng)優(yōu)化總結(jié)對(duì)共站點(diǎn)的話務(wù)情況進(jìn)行分析，對(duì)1800M站點(diǎn)話務(wù)占比低于40%的進(jìn)行重點(diǎn)調(diào)整：共計(jì)調(diào)整900M&1800M小區(qū)39個(gè)。1、整體話務(wù)占比由上圖可以看出，調(diào)整前1800M話務(wù)占比為31.56%，調(diào)整后1800M話務(wù)占比為39.37%，整體提升了7.81%。2、1800站點(diǎn)話務(wù)占比優(yōu)化前后的站點(diǎn)話務(wù)占比如下所示：小區(qū)名稱調(diào)整前1800M小區(qū)話務(wù)占比調(diào)整后1
