【摘要】 随着全球经济飞速发展,通信技术变革日新月异,我国移动通信领域取得了重要的进步。无论是在通信基础设施等硬件条件的建设方面,还是在通信质量等软件条件的提升方面都迈上了一个新台阶。然而,随着通信市场逐步迈向成熟,市场格局逐步趋向合理,庞大的通信消费在给通信企业集团带来机遇的同时,也带来了巨大的挑战。一方面,通信服务的覆盖率逐年上升,单纯靠新增入网用户数量带来红利的发展模式,势必会受到用户数量增长乏力的瓶颈限制,导致各大通信企业对用户资源的争夺日趋激烈；另一方面,为了应对激烈的市场竞争,各大通信企业不断推出各种类型的通信虚拟服务来抢占市场,试图通过降低客户资费的方式,提高客户忠诚度的目的,但是,仅仅从企业自身角度出发,快速制定出的大量虚拟服务往往很难准确把握客户的需要,不仅没有实现对市场的占有,反而形成了诸如：系统内各种同质的虚拟服务堆积、虚拟服务受众客户群有限、维护规模成本偏高以及前后期服务缺乏规划等问题,极大的影响了通信企业的核心竞争力。通信企业运营支撑系统是通信领域技术变革的重要产物,在传统模式下,其为通信企业虚拟服务的运营提供了重要的支撑。然而,在新的以虚拟服务为主体的竞争环境中,随着虚拟服务多样化需求的拓展,其对运营支撑系统的依赖已经不仅仅局限于通信业务的处理,而是对虚拟服务的全周期管理。相比而言,传统的运营支撑系统存在着系统体系结构缺乏灵活性、虚拟服务需求反应周期长、虚拟服务差异化不明显以及虚拟服务评价缺失等问题,很难适应虚拟服务的不断增长和快速变化。本文通过对通信虚拟服务系统体系结构的研究,深入分析了现阶段虚拟服务的运营状况,借助多Agent的结构模式和本体知识描述构建了基于多Agent和本体的通信领域虚拟服务系统体系结构,主要研究内容和成果如下：(1)提出了基于多Agent的通信虚拟服务系统体系框架通信虚拟服务系统的构建是一个多环节相互作用、多因素相互影响的动态、开放式问题,其主体在于通信集团和地区分公司在虚拟服务生命周期中的职能划分。本文根据这一特点,充分发挥多Agent系统在分布式计算和协作方面的优势,提出了基于多Agent的通信虚拟服务系统体系框架。(2)建立了基于动态补偿的通信公共资源冲突消解策略针对通信领域内不同虚拟服务对信道资源的分配冲突问题,本文提出了基于集团—地区分公司的组织结构和公共资源冲突消解两种模型下的各子公司Agent的协作模式建模,并提出了基于动态补偿的公共资源冲突消解策略,详细描述了基于各地区公司Agent在公共资源使用冲突时的协商途径。(3)提出了通信领域虚拟服务本体的构建方法科学有效的描述虚拟服务的知识结构是实现虚拟服务差异化、个性化的重要手段。本文为实现对虚拟服务形式化描述和推理求解,提出了通信领域虚拟服务本体的构建方法。构建方法根据通信领域多专业交叉的特点,提出了领域相关度(Domain Correlation)的概念,详细阐述了多专业本体集成的方法与模型,并针对知识推理构建了本体集成推理体系。(4)提出了基于灰色综合评价的虚拟服务评价方法本文根据虚拟服务的应用特点,从通信企业、用户和虚拟服务自身三个方而建立了虚拟服务的综合评价体系,并采用灰色模型方法对虚拟服务进行了评价,并对评价结果进行分析。更多还原

【Abstract】 With the global economy is the rapid development of communication technology changes rapidly, the field of mobile communications in China has achieved rapid development. Whether it is in the building of communications infrastructure and other hardware, and enhances communication quality software into a new level. However, as the communications market towards mature step by step, market structure gradually tends to be reasonable, which give the communicate enterprise groups opportunities, it also brings a great challenge. On one hand, the coverage of communications services increased only by relying on the number of new subscribers to bring the development model of the dividend, the limited weak growth of users will be the bottleneck, leading to major communications companies increasingly fierce competition for user resources,on other hand, in order to deal the fierce market competition, the major communications companies continue to introduce various types of virtual services to seize the market to reduce customer rates, improving customer’s loyalty purpose. Although changes in the market are difficult to control and master, in order to keep up with the changes in the market, developing appropriate policy is necessary. However, only considering from the angel of enterprise, may not grasp the needs of customers accurately, not only did the market share, but the formation of such as:the accumulation of the virtual services of the homogeneous system, the virtual service audience limited customer base, maintain the scale of high costs, as well as prior service margin of preference formation constraints and other issues, to develop post-service, great communication the company’s core competitiveness.Communications business operation support system is an important product of the communication field of technological change in the traditional mode, provides important support for the communication virtual service operations. However, in the new virtual service as the main competitive environment, the traditional operation support system there are not suitable for new demands, lacking of flexibility in architecture features, which is difficult to adapt to the growing and rapidly changing needs of virtual service.In this paper, the virtual communication service system architecture, in-depth analysis of the operational status of the virtual service at this stage, with the Multi-Agent structure model and ontology knowledge to describe virtual service system architecture based on Multi-Agent and ontology in the field of communications, mainly built content and the results are as follows:(1) Multi-Agent virtual communication service system framework Construction of virtual communication service system is a multi-link interaction, dynamic multi-factor interaction, open-ended questions, whose body lies in the allocation of functions of the Communications Group and the regional subsidiaries in the life cycle of virtual services. According to this feature, give full play to the advantages of Multi-Agent Systems in distributed computing and collaboration, and virtual communication service system framework based on Multi-Agent.(2) Establish a communication based on dynamic compensation of public resources conflict resolution strategies. For the allocation of shared resources in the field of communication in conflict situations, the two models at all levels of agent collaboration model for the Group-the organizational structure of regional offices and public resources-based conflicts digestion modeling, and proposed based on dynamic compensation public resources, conflict resolution strategies, a detailed description of each area Agent consultative approach in public resource use conflicts.(3) Communication of virtual services in the field of ontology building methods. The scientific description of the knowledge structure of the virtual services virtual service differentiation and personalized. This realization of the formal description and reasoning for solving the virtual service, virtual services in the field of ontology for communication building. Construction method to cross the characteristics of the multi-disciplinary field of communication, but also put forward the concept of relevance in the field (Domain Correlation), elaborated on a multi-disciplinary ontology integration methods and models to build a body of integrated reasoning system for knowledge inference.(4) Sets out the virtual service evaluation system based on the gray comprehensive evaluation. Characteristics of virtual services from three aspects of communications companies, users and virtual services to establish a comprehensive evaluation system of the virtual services, and the gray model method was evaluated on virtual services, and evaluation of the results were analyzed.更多还原
