【摘要】:隨著移動互聯(lián)網(wǎng)與位置信息的加速融合,基于位置服務(wù)的研究和應(yīng)用在人們的生活以及各個行業(yè)中已經(jīng)十分普遍,其中位置感知服務(wù)(Location-aware service)也已經(jīng)成為人們研究的熱門內(nèi)容。位置感知服務(wù)首先要解決的是位置定位的問題,Femtocell也稱為毫微微基站,是一種小型基站,主要的部署場景包括家庭、公司和商場等室內(nèi)場所。Femtocell具有低功耗、低成本、接入簡單、覆蓋范圍精確和即插即用的特點,同時它也不需要規(guī)劃新的頻率,也不需要建設(shè)傳統(tǒng)室內(nèi)分布系統(tǒng)。它的這些特性使得位置定位比同類技術(shù)更加高效精準(zhǔn)。通用即插即用(UPnP)是一種普遍的點對點網(wǎng)絡(luò)連接的體系結(jié)構(gòu),它適用于各種智能設(shè)備的互連。它的這種設(shè)計能提供比單一定位信息更多的周邊環(huán)境信息。本文針對如何更加高效提供位置感知服務(wù)的問題,基于Femtocell設(shè)計并實現(xiàn)了位置感知服務(wù)器。本論文研究涉及到Femtocell的技術(shù)特點和結(jié)構(gòu)、UPnP標(biāo)準(zhǔn)規(guī)范、libupnp庫的架構(gòu)和編程方法、基于Reactor模式事件驅(qū)動I/O框架的設(shè)計與實現(xiàn)、基于有限狀態(tài)機響應(yīng)流程的設(shè)計與實現(xiàn)、Protocol Buffers等。論文的主要內(nèi)容和創(chuàng)新成果有:第一,研究Femtocell和位置感知服務(wù)相結(jié)合的設(shè)計與應(yīng)用。結(jié)合Femtocell設(shè)計新的架構(gòu),使得位置感知服務(wù)更加的精確和高效。第二,為單一的定位信息加入更多周邊環(huán)境信息。研究UPnP標(biāo)準(zhǔn)規(guī)范、libupnp庫的架構(gòu)以及編程方法,用于獲取局域網(wǎng)內(nèi)的智能設(shè)備信息,使得整個服務(wù)器能提供更個性化的服務(wù)。第三,設(shè)計一套通信協(xié)議。利用Protocol Buffers數(shù)據(jù)交換技術(shù)來完成Femtocell與后臺服務(wù)器之間的數(shù)據(jù)傳輸。第四,設(shè)計一套I/O框架。基于經(jīng)典的網(wǎng)絡(luò)編程模式——Reactor模式,設(shè)計了一套事件驅(qū)動的I/O框架,后臺服務(wù)器中業(yè)務(wù)流程相關(guān)的處理都是基于此I/O框架。第五,應(yīng)用以上的設(shè)計實現(xiàn)一個基于Femtocell的位置感知服務(wù)器。
[Abstract]:With the rapid integration of mobile Internet and location information, the research and application of location-based services have become very common in people's lives and various industries, among which location-aware service has become a hot topic. The first thing to be solved by location-aware services is the location problem. Femtocell, also known as femto cell, is a small base station. The main deployment scenarios include homes, companies and shopping malls. Femtocell has low power consumption, low cost, and easy access. Accurate coverage and plug-and-play features, and it does not need to plan new frequencies, nor need to build a traditional indoor distribution system. These features make positioning more efficient and accurate than similar techniques. Universal plug and play (UPnP) is a universal point-to-point network connection architecture, which is suitable for the interconnection of various intelligent devices. This design can provide more information about the surrounding environment than a single location information. In order to solve the problem of how to provide more efficient location awareness service, this paper designs and implements a location aware server based on Femtocell. This thesis is concerned with the technical characteristics and structure of Femtocell, the framework and programming methods of the libupnp library, the design and implementation of the I / O framework based on the Reactor mode, and the design and implementation of the Buffers based on the response flow of the finite state machine. The main contents and innovations are as follows: first, the design and application of Femtocell and location-aware service are studied. A new architecture based on Femtocell is designed to make location-aware services more accurate and efficient. Second, add more environmental information to a single location information. This paper studies the architecture and programming method of UPnP standard specification / libupnp library, which is used to obtain intelligent device information in LAN, so that the whole server can provide more personalized service. Third, design a set of communication protocols. Protocol Buffers data exchange technology is used to complete the data transmission between Femtocell and background server. Fourth, design an I / O frame. Based on the classical network programming mode, reactor, an event-driven I / O framework is designed, and the business process-related processing in the background server is based on this I / O framework. Fifthly, the above design is applied to implement a location aware server based on Femtocell.
