【摘要】：隨著智能終端的迅速發(fā)展和移動應用的豐富多樣化,移動互聯(lián)網(wǎng)取得了巨大的成功。與此同時,伴隨著運營商淪為傳輸管道和信令風暴的產(chǎn)生。運營商如何面對海嘯式的數(shù)據(jù)對移動網(wǎng)絡的沖擊,提高網(wǎng)絡承載力,尤其是承載用戶最多的GPRS網(wǎng)絡仍舊是研究的重點。 本文從應用行為的角度出發(fā),在安卓手機平臺上研究即時通信類、微博類和網(wǎng)頁瀏覽類應用的網(wǎng)絡行為特征。分析應用在多種聯(lián)網(wǎng)方式、多種場景交互下的數(shù)據(jù),建立流程分析模型和流量資源開銷模型,為移動網(wǎng)絡的優(yōu)化提供了理論支持。 應用行為如心跳、頻繁短接和小流量等數(shù)據(jù)包傳輸造成了無線網(wǎng)絡資源的濫用。為了深入研究應用對網(wǎng)絡的資源消耗,量化應用對信道資源的占用。論文通過分析應用在線并且無主動交互狀態(tài)下的心跳行為,在GPRS網(wǎng)絡環(huán)境下采集終端上各場景數(shù)據(jù),結合心跳消息對無線信道資源的占用原理,評估CCCH資源消耗,建立相應分析模型。研究得出心跳的周期長短,客戶端維持心跳的種類對CCCH的資源消耗至關重要。 最后,論文基于應用的心跳機制對無線信道的消耗影響,介紹了從應用基礎層考慮的統(tǒng)一心跳推送優(yōu)化方案。通過編程仿真不同場景下的應用心跳行為,比較統(tǒng)一心跳推送機制和非統(tǒng)一心跳機制對無線網(wǎng)絡的資源消耗,驗證方案的優(yōu)越性,有效地減少了高頻次、小流量心跳數(shù)據(jù)包對信令的沖擊,為提高無線網(wǎng)絡對數(shù)據(jù)業(yè)務的承載力提供了一定研究基礎。
[Abstract]:With the rapid development of intelligent terminals and the rich diversity of mobile applications, mobile Internet has achieved great success. At the same time, with the operators reduced to transmission pipeline and signaling storm. How operators face the impact of tsunami data on mobile networks and improve the network carrying capacity, especially the GPRS network with the most users is still the focus of research. From the point of view of application behavior, this paper studies the network behavior characteristics of instant messaging, Weibo and web browsing applications on Android mobile platform. This paper analyzes the data applied in various networking modes and scenarios, and establishes a flow analysis model and a traffic resource overhead model, which provides theoretical support for the optimization of mobile networks. Application behavior, such as heartbeat, frequent short connection and small traffic, causes abuse of wireless network resources. In order to study the resource consumption of application to the network deeply, quantize the channel resource occupation of the application. By analyzing the heartbeat behavior in the online and non-active interactive state, the paper collects the scene data on the terminal in the GPRS network environment, and evaluates the CCCH resource consumption by combining the principle of the heartbeat message occupying the wireless channel resource. The corresponding analysis model is established. It is concluded that the duration of heartbeat and the type of heartbeat maintained by clients are very important to the resource consumption of CCCH. Finally, based on the effect of application heartbeat mechanism on wireless channel consumption, this paper introduces a unified heartbeat push optimization scheme considered from the application foundation layer. Through programming simulation of the application heartbeat behavior in different scenarios, the paper compares the resource consumption of wireless network by unified heartbeat push mechanism and non-unified heartbeat mechanism, verifies the superiority of the scheme and effectively reduces the high frequency. The impact of small heartbeat packets on signaling provides a basis for improving the capacity of wireless networks for data services.
