摘    要
移动通信随着其重要性的增加对服务的连续性提出较高的要求，电信级设备尤其需要具有较高的可用性。木文作者在3G核心网设备中的高可用性控制软件子系统的研制中，有感于设备的高可用性设计的复杂性，通过研究承载的平台和业务的特性，对高可用性设计需要考虑的诸多因素进行详尽分析和论证，提出基于对象的状态驱动机制、统一构建的消息转发平台、程序冗余和数据冗余分离配置的实现模型。
在设计过程中，充分地分析3G核心网设备使用的通用承载平台的特点，从可用性的角度分析其适用于高可用性控制的热插拔基础、通信基础、故障检测与控制基础，并从理论上寻求对高可用性设计的支持。通过实践上和理论上的准备，从可用性的构成因素-软硬件的可靠性和可维护性的角度出发，提出以硬件冗余和软件控制作为高可用性的实现基础，以有效地实现硬件故障处理和提高软件可靠性为实现系统高可用性地的可行的实现途径。利用基于对象的状态驱动机制作为系统控制的实现模型，解决系统中多种功能实体间逻辑关系关联控制;通过构建统一的分布式消息转发平台，确立控制系统的分层次架构和高效处理;通过程序冗余和数据冗余分离的设计，综合考虑性能和资源的统一。最后对该实现方案在逻辑上和性能上进行分析，并结合实践效果的检验，论证其已达到实现系统高可用性的目的。

Abstract
The continuous which moves correspondence along with the increment of with its importance to the service puts forward a higher request, the telecommunication class equipments needs to be had particularly higher of can use sex. The wood text author is in the 3G core net establish eachly of high can develop with the sex control software sub- system medium, there is feeling to in establish each high can use the complexity of with sex design, pass research the terrace of the loading and the characteristic of the business, to high can need many factors for considering to carry on with sex design in details analytical with argument, the appearance which puts forward according to the object drives a mechanism and unifies to set up of the news turn the hair terrace, procedure redundancy and data redundancy separation to install of carry out model.
Analyze the characteristics of in general use loading terrace that the 3G core net establishes each usage adequately during the period of designing, from can analyze it to be applicable to with the sexual angle high the heat canned use sex control put to pull out foundation, correspond by letter foundation and break down examination and control foundation, and look for from the theories to high can use support of with sex design. Pass to practice top with theoretically of preparation, from can use a sexual composing factor-the credibility of the soft hardware and can support sexual angle to set out, put forward controling with the hardware redundancy and the software conduct and actions high can use sex of carry out foundation, take carrying out hardware breakdown a processing and raising the software credibility availably as to carry out system high can use sex ground of viable carry out path. The appearance which makes use of according to the object drives mechanism as system to control of carry out model, solve system a logic relation a connection to control in various function entity; Pass to set up unitedly distribute type news to turn hair terrace, establish a layering time of controling the system structure and handle efficiently; The design separated through procedure redundancy and data redundancy, synthesize to consider function and resources to unify. Finally to should carry out a project at logical
