【摘要】2G\ 3G互操作优化是在运营商3G网络之后提出的一个全新课题,主要目标是在3G网络覆盖不足的区域,让用户在业务不间断的情况下过渡到2G网络,以多2G网络作为3G网络必要的支撑和补充。本文论述了通过进行2G\ 3G互操作的参数配置优化,使移动用户既能充分保留在3G网络上享受3G带来的优质服务,同时又要保障用户在无3G网络覆盖的区域内能够顺利过渡到2G网络上,由2G网络继续承载用户业务。2G和3G两个网络的制式不同,切换和重选算法十分复杂。日前2G \ 3G 互操作主要包括语音和数据业务的系统间切换和重选,存在包括触发门限、触发时间等数十个参数。参数配置复杂,加之可借鉴的成功经验较少,是开展2G\ 3G互操作优化研究的主要难点所在。为了解具体参数设置对互操作动作的影响,课题研究过程中采用大量测试实验的方式,对比各参数设置对实际业务的影响,结合用户感知确定最终的参数配置组合。

【Abstract】2G \ 3G interoperability optimization is in the operator after the 3G network proposed a new topic, the main goal is to cover the 3G network in the area, allowing users to uninterrupted business transition to 2G network to more than 2G network as 3G Network necessary support and supplement. This paper discusses the optimization of parameters through 2G \ 3G interoperability, so that mobile users can fully retain the 3G network to enjoy the benefits of 3G services, but also to protect users in the absence of 3G network coverage area can be a smooth transition To 2G network, by the 2G network to continue carrying the user business. 2G and 3G two networks in different formats, switching and re-election algorithm is very complex. Recently 2G \ 3G interoperability, including voice and data services between the system to switch and re-election, including the trigger threshold, trigger time dozens of parameters. Parameter configuration complex, combined with less successful experience, is to carry out 2G \ 3G interoperability optimization of the main difficulties. In order to understand the influence of specific parameter setting on the interoperation action, the author uses a large number of test experiments in the course of the research, compares the influence of each parameter setting on the actual business, and determines the final parameter configuration combination according to the user perception.

1. 前言
(1)在目前TD-SCDMA网络还不太完善和成熟的条件下,总是存在一些覆盖空洞和覆盖边缘的场强情况,若在这些区域中现有的GSM网络覆盖较好,则可以通过使用户在TD覆盖边缘和掉话的前切入到GSM网络中,以避免掉话、掉线现象,这样就减少了系统的掉话率、提高了用户感知度,从而GSM成为TD-SCDMA网络的有效补充和辅助手段。
(2)同时,当TD网络足够好时,应使用户及时重选到TD网络,尤其对于数据业务,以保证用户对TD业务的使用及感知。……
