TD-SCDMA与WCDMA网络优化及切换方式比较

Contrast of TD-SCDMA and WCDMA by Optimized Mode and Signaling Switch

TD-SCDMA采用接力切换方式,WCDMA采用软切换方式,这是两种3G制式在移动性管理上的主要差异。但是在现场测试中可以发现设计切换的信令流程有着许多相似之处,但是两者在切换控制思想上有着很大的不同。同时在优化过程中也有着一定区别,网络优化是保证网络业务质量、充分利用网络资源的重要手段。对网络进行不断的优化,不仅是为了提高用户满意度,更可节约运营商的建设维护成本,提高其市场竞争力。

TD-SCDMA uses Relay switching mode, WCDMA uses soft handoff mode, which is the major differences between them. However, the test can be found that the process of both switch signaling has many similarities, but the control of switching is different. The optimization process also has a certain distinction, network optimization is an important means to ensure the quality of service and take advantage of network resources. Continuous optimization of the network is necessary, not only to improve the satisfaction of customer, but also can save the costs of maintenance, and increase their competitiveness.
