摘要
蜂窝数字分组数据（ＣＤＰＤ）是利用现有的模拟蜂窝电话网来传输数据的一种新技术。无线资源管理协议负责为ＣＤＰＤ数据流选择一个合适的信道进行数据传输。通过建立一个话音模型，对ＣＤＰＤ 如何选择信道才能获得最佳的数据传输作了理论分析和探讨。
The cellular digital packet data(CDPD) is a system which borrows idle radio channels from the existing cellular mobile telephone networks for packet data transmission.Radio resource management protocol is in charge of selecting one better channel for CDPD data transmission.In this paper,by constructing a model of voice,we investigate some channel assignment strategies for both the AMPS and the CDPD system and their effects on the CDPD channel holding time.
