Through the analysis of IS95 technology architecture, it is pointed out that IS95 system is an optimized system under specific working mode but not the best system for overall situation. As for CDMA technology itself, the working mode and the corresponding technology architecture of IS95 system is not the best solution to realize CDMA technology. Based on the summary of the general features of CDMA system, several aspects for CDMA to progress further are presented in this paper.

分析了CDMA系统在不同工作模式(双工方式、信道关系和射频带宽)下的特性,进而分析了IS95采用的扩频、抗多径效应、严格功率控制和负荷平衡控制等一系列系统技术.结果表明,IS95在其选定的工作模式下是一个优化系统,但只是一个局部优化的CDMA系统.IS95系统应用扩频技术获得了目前所有移动多址系统的最高容量,但为了降低多址干扰而使技术复杂性、系统成本均有所增加,且系统的实际容量只达到设计值的 1/3强.CDMA还有其他工作模式尚待发掘.

The tilted-antenna mechanism is an effective way to balance the traffic and improve the capacity of CDMA cellular system. Through the investigation of handoff problem in the fixed tilted-antenna mechanism, a new model of analyzing the system capacity is presented, in which the quality of the integrated channel is considered. Because of integrating both the forward link and reverse link into consideration, the proposed method consequently can lead to much more reasonable results of the system capacity. Optimized...

The tilted-antenna mechanism is an effective way to balance the traffic and improve the capacity of CDMA cellular system. Through the investigation of handoff problem in the fixed tilted-antenna mechanism, a new model of analyzing the system capacity is presented, in which the quality of the integrated channel is considered. Because of integrating both the forward link and reverse link into consideration, the proposed method consequently can lead to much more reasonable results of the system capacity. Optimized tilted angles of the antenna of a base station, under the condition of uniform or non-uniform user distributions, are investigated. The simulation results show that by the new model, the actual system capacity can be greatly improved compared with the results by the model with the reverse link only.

地面基站天线倾斜是提高CDMA蜂窝系统容量和平衡小区负载的有效方法之一。本文通过对倾斜天线蜂窝系统的切换问题的研究 ,提出了在计算系统容量时 ,同时考虑前向信道和反向信道的双向信道分析方法 ,使得系统容量的计算更为合理。利用这一模型 ,得出了在用户均匀分布和非均匀分布情况下的最佳天线倾斜角度。仿真结果表明 ,利用本文的方法 ,系统的实际容量比单独考虑反向信道时有显著的提高。

The designing of a GPRS network scale should be based on the number of clients that can be activated simultaneously. As in some regions where exists much difference between the registered client number, attached client number and activated client number, close attention should be paid to network statistical data and network operation...

The real capacity and existing problems of General Packet Radio Service (GPRS) network are analyzed and its construction principle, planning scheme and security policy are discussed. The designing of a GPRS network scale should be based on the number of clients that can be activated simultaneously. As in some regions where exists much difference between the registered client number, attached client number and activated client number, close attention should be paid to network statistical data and network operation status, and then the supporting capability of GPRS core network can be accordingly obtained. As to system security, two issues in both the technological level and management level should be considered.

文章分析了当前GPRS网的实际容量和存在的主要问题,探讨了GPRS核心网建设规划方案和安全策略。文章认为在设计GPRS网络建设规模时要按照能够同时激活的GPRS客户规模为基础进行测算;针对部分地区出现GPRS登记用户规模、附着用户规模、激活用户规模3者差异较大的现象,在进行GPRS网络建设时要密切观察网络统计数据,跟踪GPRS网络运行状况,并提出相应的GPRS核心网设备支持能力的要求;对GPRS系统的安全,应同时考虑安全技术和安全管理两个方面。
