摘要
随着3G技术的日臻成熟,高数据吞吐的优势使得无线网络与移动手机的融合成为必然趋势,目前智能手机的不断普及,移动应用的需求也与日俱增。移动互联网因其具有随身性、可鉴权、可身份识别等独特优势,为传统的互联网类业务提供了新的发展空间和可持续发展的新商业模式。但移动互联网业务在便携的同时,也受到了无线网络传输环境、技术能力、终端大小、处理能力、电池容量等的限制。
     目前,基于人们社会生活节奏越来越快,一种从Android平台提供的地理位置服务的基础上延伸出来的更多顾及人们生活的智能服务平台应运而生。
     本文首先介绍了Android平台和Agent技术的相关理论基础。然后将Agent技术引入系统,分析了身份Agent的功能,阐述了身份Agent的个体控制,并且在此基础上建立了基于管理Agent的多Agent协作模型,从而有效的解决了身份Agent之间的协调问题,是实现位置信息智能服务系统的一种有效和可行的方案。接下来在分析个体地理位置浮动变化的基础上,提出了一种的基于位置的邻域链接算法。该算法解决了本系统中怎么获取群聚体的问题,对后续智能焦点确定算法的完成夯实了有力的基础。通过复杂度分析证明了算法的可行性。紧接着对集聚焦点确定思路建立起Agent协商模型,提出了一种基于Agent的集聚焦点确实算法,该算法主要是完成集聚过程中个体协商的智能化过程,最后对算法做了满意度评估计算。在以上研究的基础上,借助Android平台成熟框架,提出了整个系统的物理架构和完整的系统结构,系统设计由服务器端的设计和终端的设计组成,在服务器端,我们按照设计的需要对其功能进行划分。在终端的设计中,考虑智能手机作为一种常见的嵌入式系统,受限于其自身资源制约,终端地理位置服务的设计包括对UI图形设计、UI接口设计、逻辑过程设计和无线通信设计。接着阐述并分析了系统主要模块的功能。
     本文最后对系统实现过程中的研究工作与关键技术进行了总结,并提出了将来进一步对该系统进行扩充与完善的一些工作。
As 3G technology has been increasingly matured, the advantages of high data throughput make the convergence of wireless network and mobile phones inevitable. Currently, with the popularity of smart phones, the demand of mobile applications has also been increased. Owing to Mobile Internet's portable nature, authentication, identification, it affords traditional Internet services a new space for development and sustainable development, new business models. However, the mobile Internet business is restricted by the wireless network transmission environment, technical capacity, terminal size, processing power, battery capacity, etc.
     At present, due to the rapid development of economy, the pace of social life has been growing faster. Based on this, a more intelligent service platform taking people's lives into account has come into being, which is based on the geographical location services of the Android platform.
     Firstly, this thesis introduces the Android platform and the related theoretical basis of Agent technologies. Then, Agent technologies are applied to the system. The features of Identity Agent are analyzed and also its individual control mechanism is described. Based on this, Multi-Agent Collaboration model based on management Agent is constructed, which effectively solves the issue of coordination among Identity Agents and it is an effective and viable option to the implementation of intelligent location information service system. Next, a neighborhood of location-based link algorithm is proposed, which is based on the analysis of the geographical location's floating. The algorithm solves the problem how to obtain the cluster body in the system and it establishes a strong foundation for the following intelligence focus determing algorithm. The algorithm is mainly to complete the intelligence process of individual negotiation in the process of gathering, Moreover, it is also proved that this algorithm is feasible by its complexity analysis. This thesis also provides a concept for the focus of assembly and Agent negotiation model is constructed, and then an algorithm based on Agent is proposed and satisfaction assessment calculations are made. Upon the above research, the thesis proposed physical architecture of the whole system and a complete system architecture, the system design is composed by the server-side design and the terminal design, on the server side, it divides its functions according to the need of design. In the terminal design, considering of intelligent cellphone as a common embedded system, limited by its own resource constraints, the design of terminal geography location service includes UI graphics design, UI interface design, logic process design and wireless communication design. Then Expounds and analyses functions of the system's main modules.
     Finally, the summarization of the whole research work and the key technologies is generalized; the improvement of the system in the future is also discussed in the end.
