【摘要】：移動互聯(lián)網(wǎng)和智能手機終端的迅猛發(fā)展使得數(shù)據(jù)流量迎來爆炸式增長的同時,高QoS需求的電信級IP業(yè)務逐漸成為焦點,流量經(jīng)營正是用于解決這類問題。3GPP針對流量經(jīng)營提出了PCC架構,在2/3G網(wǎng)絡中的PCC架構主要側(cè)重于流量疏導和管控,在LTE網(wǎng)絡中PCC架構在2/3G PCC架構的基礎上加入了差異化服務這一特性,以提升高價值用戶的體驗,運營商借此緩解數(shù)據(jù)流量增量不增收等問題,增加數(shù)據(jù)流量方面的收入,提升競爭力。 本文在現(xiàn)網(wǎng)PCC架構上加入網(wǎng)元PA (Proxy Agent),對新增網(wǎng)元PA以及其他核心網(wǎng)網(wǎng)元、接口的功能分別提出了改進方案,還對整個PCC流程在2/3G PCC流程的基礎上做出了改進與完善。本文針對特定PCC應用場景,詳細設計了演進的PCC架構的具體信令流程。根據(jù)上述特點,業(yè)務平臺可以依照網(wǎng)絡狀況實時地調(diào)整業(yè)務服務質(zhì)量,提升用戶體驗�；跇I(yè)務平臺使用HTTP協(xié)議,移動核心網(wǎng)信令使用Diameter協(xié)議,本文在最后針對新增網(wǎng)元PA的協(xié)議轉(zhuǎn)換功能做出了詳細設計,包括抓包分析Diameter協(xié)議,QoS參數(shù)的設計,兩種協(xié)議之間QoS參數(shù)如何映射的設計等。經(jīng)分析,上述設計基本可行,使用本文提出的演進的PCC架構,用戶體驗明顯提升,該架構對于特定應用的控制流程以及該架構相較于2/3G PCC架構具有一定的優(yōu)勢。論文最后總結(jié)了本文提出的演進的PCC架構的優(yōu)勢與不足,并對本文下一步工作進行了展望。
[Abstract]:With the rapid development of mobile Internet and smart phone terminal, the data traffic is growing explosively, and the telecom IP service with high QoS demand is becoming the focus. Traffic management is used to solve this kind of problem. 3GPP proposed a PCC framework for traffic management. The PCC architecture in 2 / 3 G network mainly focuses on traffic diversion and control. In the LTE network, the PCC architecture adds the characteristic of differentiated service on the basis of the 2 / 3G PCC architecture to enhance the experience of high-value users, so that the operators can alleviate the problem of increasing the data traffic increment and increase the revenue of the data traffic. Enhance competitiveness. In this paper, the PA proxy agent is added to the current network PCC architecture, and the functions of the new network element PA and other core network elements and the interface are proposed respectively. The whole PCC process is improved and perfected on the basis of the 2 / 3 PCC process. This paper designs the specific signaling flow of the evolving PCC architecture in detail according to the specific PCC application scenario. The service platform can adjust the service quality of service and improve the user experience in real time according to the network condition. Based on the service platform, the HTTP protocol is used, and the Diameter protocol is used in the mobile core network signaling. At the end of this paper, the protocol conversion function of new network element PA is designed in detail, including the design of Diameter parameters, how to map QoS parameters between the two protocols, and so on. Using the evolving PCC architecture presented in this article, the user experience has improved significantly, This architecture has some advantages over 2 / 3G PCC architecture and the control flow of specific application. Finally, the paper summarizes the advantages and disadvantages of the evolving PCC architecture proposed in this paper, and looks forward to the future work of this paper.
