【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。
[Abstract]:With the rapid development of the global economy and the changing of communication technology , it has made important progress in the field of mobile communication .
On the other hand , in order to deal with the fierce market competition , each major communication enterprise continuously launches various kinds of communication virtual services to seize the market , and attempts to improve the customer loyalty through reducing the customer ' s tariff . However , it is difficult to accurately grasp the customer ' s needs by reducing the customer ' s tariff . Instead , it has not only realized the occupation of the market , but also formed the problems such as the accumulation of various homogeneous virtual services in the system , the limited customer base of the virtual service , the high cost of the maintenance scale and the lack of planning of the service in the former later period , and greatly influences the core competitiveness of the communication enterprises .

The operation support system of communication enterprises is an important product of technological change in communication field . In the traditional mode , it provides an important support for the operation of virtual service in communication enterprises . However , in the new competitive environment based on virtual service , its reliance on the operation support system is not limited to the processing of the communication service , but the full cycle management of the virtual service . In contrast , the traditional operation support system has the problems of lack of flexibility in the system architecture , long response period of the virtual service , lack of virtual service differentiation and lack of virtual service evaluation , etc . It is difficult to adapt to the growing and rapid change of the virtual service .

Based on the research of the architecture of communication virtual service system , this paper deeply analyzes the operation status of virtual service at present , and constructs a virtual service system architecture based on multi - agent and ontology based on multi - agent structure model and ontology knowledge description . The main research contents and results are as follows :

( 1 ) The framework of multi - agent communication virtual service system is proposed .

The construction of communication virtual service system is a multi - link and multi - factor dynamic and open problem . Its main subject lies in the functional division of communication group and regional branch in the life cycle of virtual service . According to this feature , the advantage of multi - agent system in distributed computing and collaboration is brought into full play , and the framework of multi - agent communication virtual service system is proposed .

( 2 ) establishing a communication public resource conflict resolution strategy based on dynamic compensation ;

Aiming at the problem of allocation conflict of different virtual service to channel resources in communication field , this paper puts forward the collaborative model modeling of each subsidiary agent based on the organization structure and public resource conflict resolution of the group - region subsidiary company , and puts forward the public resource conflict resolution strategy based on dynamic compensation , and details the negotiation route of the agent in the use of public resources based on the regional company agent .

( 3 ) The construction method of virtual service ontology in communication field is proposed .

In order to realize the formal description of virtual service and the solution of reasoning , this paper proposes the construction method of virtual service ontology in the field of communication . The paper presents the concept of domain correlation based on the characteristics of multi - discipline crossing in communication field , and describes the method and model of domain correlation in detail , and constructs ontology integrated reasoning system for knowledge reasoning .

( 4 ) The virtual service evaluation method based on grey comprehensive evaluation is proposed .

According to the application characteristics of virtual service , this paper establishes a comprehensive evaluation system of virtual service from three parties of communication enterprise , user and virtual service , and evaluates the virtual service using the grey model method , and analyzes the evaluation result .
