华为UMTS分布式解决方案涵盖了分布式接入 网,R4软交换核心网两大领域。在接入网部 分,围绕“降低站点获取难度,节省OPEX”这一核 心需求,遵循CPRI标准,把基站按照功能单元进行 分解:射频单元拉远,便于室外安装;基带部分小型 化,便于与现有站点共存。核心网部分,坚持“降低 OPEX成本,适应未来演进”的方向,采用软交换技 术,通过分布式架构来适应多种接入网的接入。
Huawei UMTS distributed solution covers the distributed access network, R4 softswitch core network two major areas. In the part of access network, around the core requirement of “reducing the difficulty of site acquisition and saving OPEX”, following the CPRI standard, the base station is decomposed according to functional units: the radio frequency unit is extended for outdoor installation; the baseband part is miniaturized and convenient Coexist with existing sites. Core network, adhere to the “reduce OPEX costs, adapt to the future evolution,” the direction of the use of softswitch technology, through a distributed architecture to adapt to a variety of access network access.
