U900广覆盖外围站点回撤研究

Retracement Analysis of U900 Wide-coverage Peripheral Base Stations

基于运维、建设成本等因素,对U900广覆盖外围站点的传输接入策略"站点回撤"进行了分析,旨在维持架构稳定的前提下,收缩外围站点,提升综合业务接入点的接入效率,不在外围低价值区域增大投资,同时降低运营维护成本、提升站点带宽并增加后期作为LTE热点的分组接入比例。以某省联通为例,围绕上述几个问题对传输接入应对策略——"站点回撤"进行了探讨,建立了回撤模型,并对站点回撤策略及回撤步骤进行了分析。

The retracement analysis of U900 wide-coverage peripheral base station is based on the factors of maintenance costs,con-struction costs and so on. The premise is to maintenance the stability of the infrastructure,and the contraction of peripheral stations,the access-utilization promotion of integrated-access stations without increasing investments on low value regions, and the improvement of the terminal bandwidth and the late LTE packet-access proportion meanwhile decreasing the mainte-nance costs are the goals. It takes a provincial branch of China Unicom as an example,focusing on the above mentioned facts, establishes the retracement model and analyzes the retracement strategy.
