摘要
随着无线通信技术的飞速发展,人们越来越期望移动网络可以随时随地为用户提供可靠的
服务。不同的用户对网络延迟以及丢包率等方面的要求也不尽相同。如何在第三代移动通信网
络中给不同类型的用户提供不同的服务质量,是每一个运营商和设备制造商重点关注的问题。
本文设计的硬件和软件模块就是为了实现 CDMA2000 移动通信系统核心网设备的 QoS 功能,
以满足移动用户的需求。
多核物理单板是核心网设备的基础硬件单元,本文在对其设计架构和工作机制进行分析
后,根据 3GGP2 组织制定的高速分组数据网络 QoS 架构标准,采用结构化和模块化处理的开
发方式,将 QoS 功能分为用户面、媒体面和管理面三个部分,并分别进行了详细设计和实现。
而且在 QoS 用户面和 QoS 媒体面大模块里根据各个小模块的处理情况,将相同或相关联的部
分功能集合在一起,采用分层模式实现整体的功能。最后在硬件平台上搭建了一个稳定可靠的
模拟通信环境,并针对 ACL 功能和 QoS 功能设计了相应的测试方法和通过准则,为后续测试
做了充分的准备。

CDMA2000 系统核心网 QoS 功能的设计与实现
ABSTRACT
With the high-speed development munication, all users wish municate with others
at every moment and everywhere. Different users need different delay-time and packet-loss-ratio.
work should provide different quality of service to different users, so how to resolve this
problem in the 3rd generation mobile system is an important issue for every carriers and equipment
manufacturers. The hardware and software modules designed in this paper are to implement QoS
functionality in the work equipment of CDMA2000 system, so that it can meet the needs of
mobile customers.
The multicore board is the basic hardware unit in the work equipment. In the wake of
analyzing the design structure and working mechanism, we took the development of structured and
modeled way, the QoS function is designed and implemented sepearately in aspects of user side,
media side and management side accrording to architechture standard of the QoS Model in HRPD
made by anization. Regarding user side and media side, we collected the same or relative
models and implement the overall function using stratified pattern. At last, we established a stable and
reliable simulation environment based on hardware platform, designed the accordingly test methods
