摘    要
移動通信隨著其重要性的增加對服務的連續性提出較高的要求，電信級設備尤其需要具有較高的可用性。木文作者在3G核心網設備中的高可用性控制軟件子系統的研制中，有感于設備的高可用性設計的復雜性，通過研究承載的平臺和業務的特性，對高可用性設計需要考慮的諸多因素進行詳盡分析和論證，提出基于對象的狀態驅動機制、統一構建的消息轉發平臺、程序冗余和數據冗余分離配置的實現模型。
在設計過程中，充分地分析3G核心網設備使用的通用承載平臺的特點，從可用性的角度分析其適用于高可用性控制的熱插拔基礎、通信基礎、故障檢測與控制基礎，并從理論上尋求對高可用性設計的支持。通過實踐上和理論上的準備，從可用性的構成因素-軟硬件的可靠性和可維護性的角度出發，提出以硬件冗余和軟件控制作為高可用性的實現基礎，以有效地實現硬件故障處理和提高軟件可靠性為實現系統高可用性地的可行的實現途徑。利用基于對象的狀態驅動機制作為系統控制的實現模型，解決系統中多種功能實體間邏輯關系關聯控制;通過構建統一的分布式消息轉發平臺，確立控制系統的分層次架構和高效處理;通過程序冗余和數據冗余分離的設計，綜合考慮性能和資源的統一。最后對該實現方案在邏輯上和性能上進行分析，并結合實踐效果的檢驗，論證其已達到實現系統高可用性的目的。

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
