第三代通信网络的特点决定了规划的主要思想是:全面规划,分步实施。容量规划是无线网络规划中必不可少的内容,而混合业务下的小区容量是容量规划中的重点和难点。文中研究了坎贝尔算法,根据GSM的现网用户数以及话务量,提出了一种基于坎贝尔算法的TD-SCDMA容量预测方法,并通过算例分析得到了GSM的容量和TD-SCDMA的容量之间的关系,以便能对3G混合业务下的容量设计有所借鉴。
The characteristics of the third generation communication network determine the main idea of planning is: comprehensive planning, step by step implementation. Capacity planning is an indispensable element in wireless network planning. The capacity of a cell under hybrid services is a key and difficult point in capacity planning. In this paper, the Campbell algorithm is studied. According to the number of subscribers and the amount of traffic in the GSM network, a method of TD-SCDMA capacity prediction based on the Campbell algorithm is proposed. The capacity of GSM and the capacity of TD-SCDMA So as to draw lessons from the capacity design of 3G mixed services.
