【摘要】：開放業(yè)務(wù)接口是NGN的一大優(yōu)勢，為提高電信運(yùn)營商的效益和用戶網(wǎng)絡(luò)體驗(yàn)，開放業(yè)務(wù)接口成為業(yè)內(nèi)關(guān)注和研究的熱點(diǎn)。廣大Web應(yīng)用開發(fā)者可通過Web接口使用電信網(wǎng)絡(luò)的能力，也加快了第三方服務(wù)和應(yīng)用提供商的開發(fā)速率。Parlay X架構(gòu)的出現(xiàn)引起了廣泛的注意，通過Web ServiceAPIs為應(yīng)用提供網(wǎng)絡(luò)會話控制能力。 首先，介紹了NGN多業(yè)務(wù)通信與交換平臺的關(guān)鍵技術(shù)的研究背景以及研究目的和意義，，闡述了SOA相關(guān)技術(shù)的發(fā)展歷程，結(jié)合當(dāng)前研究現(xiàn)狀提出本文的研究方向。 其次，綜述了NGN多業(yè)務(wù)通信與交換平臺的關(guān)鍵技術(shù)所需要的技術(shù)和理論思想，對ParlayX網(wǎng)關(guān)過載控制技術(shù)進(jìn)行了研究，并結(jié)合前人研究成果提出了一種基于消息的過載控制算法。該算法結(jié)合Parlay X架構(gòu)特點(diǎn)和消息類型，對消息的進(jìn)行優(yōu)先級設(shè)置，并結(jié)合負(fù)載均衡和接入控制算法，利用相關(guān)過載變量，控制消息發(fā)送數(shù)量，從而對網(wǎng)關(guān)進(jìn)行過載控制。仿真實(shí)驗(yàn)表明，相比于傳統(tǒng)的過載控制算法，本算法能保證更大的吞吐量和更少的平均服務(wù)時(shí)間。 最后，在上述研究的基礎(chǔ)上，分析了Parlay X所在環(huán)境的總體架構(gòu)，網(wǎng)關(guān)接口，詳細(xì)設(shè)計(jì)了Parlay X網(wǎng)關(guān)所需的各個(gè)模塊，并對網(wǎng)關(guān)的實(shí)現(xiàn)進(jìn)行詳細(xì)介紹。之后，以VS2010為開發(fā)平臺，使用C++開發(fā)語言，MySql作為數(shù)據(jù)庫，實(shí)現(xiàn)并測試了該系統(tǒng)。
[Abstract]:Open service interface is one of the advantages of NGN. In order to improve the efficiency of telecom operators and user network experience, open service interface has become the focus of attention and research in the industry. The ability of Web application developers to use telecommunication networks through Web interfaces has also accelerated the development rate of third-party services and application providers. Parlay X architecture has attracted widespread attention. Web ServiceAPIs provides network session control for applications. Firstly, this paper introduces the research background, purpose and significance of the key technologies of NGN multi-service communication and switching platform, expounds the development course of SOA related technologies, and puts forward the research direction of this paper combined with the current research situation. Secondly, this paper summarizes the key technologies and theoretical ideas of NGN multi-service communication and switching platform, studies the overload control technology of ParlayX gateway, and proposes a message-based overload control algorithm combined with the previous research results. Combined with the characteristics of Parlay X architecture and message types, the algorithm sets the priority of messages, and combines the load balancing and access control algorithms, using the relevant overload variables to control the number of messages sent, so as to control the gateway overload. Simulation results show that compared with the traditional overload control algorithm, the proposed algorithm can guarantee greater throughput and less average service time. Finally, on the basis of the above research, the overall architecture and gateway interface of Parlay X are analyzed, and the modules needed for Parlay X gateway are designed in detail, and the implementation of the gateway is introduced in detail. After that, the system is implemented and tested with VS2010 as the development platform and C development language, MySQL, as the database.
