Study On The Self-Adaptive Mechanism Of The Telecommunication Network Structure System And The Urban Function Module System

Study on the Self-Adaptive Mechanism of the Telecommunication Network Structure System and the Urban Function Module SystemIn recent years, with the rapid economic development and rapid expansion of city size, urban functions become more complex, diverse. Meanwhile, the spatial structure of urban functions is continuously optimizing, and functional area is moving towards the function module. Telecommunication network system is one of the most important urban infrastructures, which provides an important communication support for the efficient operation of the urban function. The development of telecommunication network objectively meets all economic entities of the urban needs for the information exchange, which makes the boundaries of temporal and spatial distance broken, and fundamentally changes people's style of work and lives. The development of telecommunication network promotes the agglomeration effects of the urban economic elements, and makes the spatial form of urban functions changed greatly simultaneity. Telecommunication network structure system and the urban function module system have a relationship of mutual promotion, mutual influence and mutual constraint. Telecommunication network structure system and urban function module system exposed to all sorts of unavoidable problems in the process of coordination, and they are:First, there are contradictions between the development strategy of telecommunication network and the urban function module. The development strategy of urban function module which is composed of sub-strategies at different levels is an overall development strategy of urban function, and the development strategy of telecommunication network is a sub-strategy of the overall strategy. The overall strategy improves the whole function of the urban system, and moreover, sub-strategy must be adjusted in accordance with the requirements of the overall strategy to meet the development requirements of the overall strategy. However, due to the current rapid expansion of telecommunication network, the development strategy of telecommunication network is at a stand-alone stage, and it is not form an effective synergy with the urban function module strategy. So it leads to an imbalance development between telecommunication network system and urban function module system.Second, there is an uncoordinated development between telecommunication network structure system and urban function module system. With the development of economy, the size of urban has an expansion and urban function spatial structure also has a great change. The structure of urban changes from the original single center to a multi-center structure, meanwhile, functional area also changes from the original mixed partition to the current urban functiona module,which has been formed a functional pattern of multi-center structure and multi-functional module. Since the development of telecommunication network system has maintained a rapid growth, it lacks of flexibility when faces the new situation and new trend of urban functions.Third, the plan of telecommunication network has an aggressive expansion, but the future development direction of the network is not clear. Teleommunication network has a feature of whole network. When facing a huge market demand, the major operators pull out all the methods to increase the telecommunication network coverage and seek to "carpet bombing" in the urban. Facing the rapid expansion of telecommunication network, although for the purpose of capturing the market opportunities, it lacks an in depth analysis of urban functional module characteristics. At last, it appears a situation that telecommunication network does not match with the actual needs and has not a clear direction for the future network.Fourth, the layout of network construction has been confused, and the urban landscape has been damaged. When the telecommunication network seeks to "carpet bombing" in the city, blind construction, illegal construction and confused layout are nothing a new case. For example, telecommunication network may appear over the city, underground or even the roof. With the development of urban ecological landscape function and the concepts of livable and eco-city, a higher requirement for telecommunication network has been proposed to prohibit the form of "patching, sewing zipper" in the future.The existing variety of problems make the development process of the telecommunication network structure system and the urban function module system encounter great difficulties. To solve this problem is to find its internal following rules, so this paper researches the self-adaptive mechanism of telecommunication network structure system and the urban function module system from the perspective of self-adaptive, and designs a mechanism and ways to solve the problems.The first step is basing on the analysis of domestic and foreign theory and related fields literature, meanwhile, this paper does an in-depth study of telecommunication network structure system and the urban function module system. Since the concepts of telecommunication network structure system and the urban function module system are the first proposed in this paper, this paper defines the concepts, contents and boundaries of the two systems, and also researches the relationship and characteristic of them. Then we discuss the common factors and special factors of the subsystem and parent system.This paper analyzes the self-adaptive dissipation characteristics of telecommunication network structure system and the urban function module system, and they are open, far from equilibrium, a small fluctuation and nonlinear interaction. It also applies entropy theory to analyze the entropy generation process of the telecommunication network system and the urban function module system. It studies the relationship between entropy generation and dissipation structure in the subsystem and parent system, then proposes entropy factors and establishes entropy model. Meanwhile, basing on entropy and dissipative structure theory, this paper builds self-adaptive dissipative structure model of the telecommunication network system and the urban function module system, then studies the differences of self-adaptive dissipation between telecommunication network system and different urban function models.This paper applies synergetics theory to describe the self-adaptive process of the telecommunication network structure system and the urban function module system, and studies synergetic evolution principle between the two systems systematically. And then we get a conclusion that because of the systematic synergetic evolution, the subsystem self-adapts the mother system. On this basis, it in-depth studies the self-adaptive order parameter and control parameter in the telecommunication network structure system and the urban function module system. This paper makes telecommunication services innovation capability as the order parameter and establishes the self-adaptive order parameter evolution equation. So this paper analyzes the order parameter influence the adaptation of subsystem and mother system. At the same time, this paper studies the self-adaptive power source of subsystem and mother system. Putting the order parameter as an internal driving force and the control parameter as an external driving force, the paper establishes an adaptive power model of the telecommunication network subsystem and the urban function module mother system.This paper applies the core idea of CAS to analyze self-adaptive features of the agents of telecommunication network structure system, and construct self-adaptive model of the agents of telecommunication network structure system and the urban function module system. The paper studies the self-adaptive process of the agents of telecommunication network structure system (fixed telephone network agent, mobile communication network agent, and broadband communication network agent). This paper studies self-adaptive collaboration strategy of the telecommunication network structure system and the urban function module system, and analyzes the mechanism of the system strategic adaptive collaboration. So we propose seven key elements of collaboration, and discuss the model of strategic adaptive collaboration of the telecommunication network structure system and the urban function module system. It also researches self-adaptive aggregation collaboration of the telecommunication network structure system and the urban function module system. Through analyzing the similar and heterogeneous aggregation of telecommunication network structure system, and the urban aggregation effect and the evolution of urban function module, this paper considers that urban aggregation and functional evolution influence the telecommunication network structure system. This paper applies the CAS theory to analyze the adaptive evolution cooperation of the telecommunication network structure system and the urban function module system. We discuss the external performance of the two systems, and build the two system's self-adaptive evolution model. At last, we analyze in-depthly the mechanism of system adaptive evolution cooperation.Basing on the above theories, this paper does an evidence and application of the transmission network rolling planning case of China Mobile Communications Group Inner Mongolia Company Limited Huhehot branch from 2011 to 2013. Through the theoretical research and empirical testing, this paper identifies the existing problems and proposes some relevant measures.
