摘要

回程链路的经常性运营成本是蜂窝服务提供商关注的关键问题。回程是连接基站到中央局基站控制器(BSC)的链路(或中继)。从2G向3G无线接入网迁移的动力之一是采用分组交换技术实现回程效率的最大化。一条回程链路所能支持的最大呼叫数称为回程效率。两种主要技术，ATM(特别是AAL2)和IP，是3G提供的主流。我们将这两种技术的回程效率与2G电路交换回程效率进行了比较。还考虑了与3G AAL2/IP回程相关的QoS。

On the backhaul efficiency of 3G CDMA radio access network

The recurring operating costs of backhaul links are of key concern to cellular service providers. Backhaul are the links (or trunks) that connect base stations to the base station controller (BSC) in the central office. One of the driving forces to migrate from 2G to 3G RAN (radio access networks) is to maximize the backhaul efficiency by adopting packet-switched technology. The maximum number of calls a backhaul link can support is called the backhaul efficiency. Two major technologies, ATM (specifically, AAL2) and IP, are the main streams offered in 3G. We compare the backhaul efficiency of these two technologies with 2G circuit-switched backhaul efficiency. QoS associated with the 3G AAL2/IP backhaul is also considered.
