TECHNICAL AND COMPARATUS FOR PROVIDING ARRANGment AND INTERACTIVE OF components considering various COMMUNICATION environment}

The present invention relates to a communication system for improving a ubiquitous mobile communication service, and more particularly, to a communication system in which components are disposed in consideration of a communication environment so as to provide a user-oriented service in various communication environments, and a service providing method using the same. It is about.

The present invention is derived from the research conducted as part of the IT growth engine technology development project of the Ministry of Knowledge Economy and the Ministry of Information and Communication Research and Development. [Task management number: 2006-S-001-02, Title: Adaptive wireless access for 4G mobile communication And transmission technology development].

The next generation mobile communication system seeks to provide a ubiquitous mobile communication service that can be used anytime and anywhere through any terminal, which means providing a user-centered service. This ubiquitous mobile communication service should allow users to enjoy various and convenient services on the go without any charges, and should use high-capacity real-time services such as video calls, streaming, and video on demand at higher bandwidths in wireless and mobile environments. In addition, through the collection and exchange of contextual information, it should be possible to provide services appropriate to the situation through processes such as interpretation and reasoning.

In the next generation mobile communication environment, wireless communication technologies suitable for various applications and environments will be superimposed. In this case, the user should be able to provide the most suitable access service to the surrounding network, device, service, and the like.

In addition, the society must be diversified, and services tailored to users should be provided according to personalization of life and diversification of needs, and various services such as vertical movement and horizontal movement should be guaranteed to provide seamless services. . Lastly, users should use the service more safely, and privacy, privacy and reliability should be considered.

In order to provide a ubiquitous mobile communication service, an analysis of a wireless access environment in which wireless communication is performed is required. Classify and define communication environment by analyzing physical wireless channel characteristics such as user mobility, probability of visible line presence, delay spread and fading effects. Based on this, it is possible to define required services and available services according to various communication environments. Can be.

In order to provide user-oriented services, characteristics and requirements of each service should be set in consideration of all possible services that a user can request. The WINNER project, a study for the next generation mobile communication system in Europe, classifies the services that users can request into 18 categories, and prioritizes the services in consideration of delay and transmission rate.

However, it only considers the characteristics and requirements of the service and does not take into account user preferences and service efficiency in various communication environments. Therefore, it does not provide enough services to meet user needs in various communication environments and thus cannot provide true user-oriented services.

Existing cellular systems provide efficient service to all areas by continuously installing and communicating a certain sized service area called a cell. However, due to the optimization of voice calls, high-cost large data transmission and reception costs are high, and compatibility between networks using different wireless access standards or communication networks provided by different providers is difficult. In addition, WLANs providing services requiring high data rates over broadband within a limited area are also very difficult to be compatible with current cellular networks. In other words, in the existing mobile communication system, communication system components are arranged around the system according to the purpose of each communication network, and each communication network or service provider allocates a specific band and uses only fixed radio resources. It is difficult to provide services according to communication environment, and wireless resource reuse is inefficient.

Accordingly, the present invention proposes a method for arranging communication system components and interworking between components in consideration of a communication environment in order to provide a user-oriented service in various communication environments in providing a ubiquitous mobile communication service. I would like to.

In addition, the present invention is to arrange the components of the communication system to provide a user-oriented communication service according to the communication environment by analyzing the physical radio channel characteristics such as the mobility of the user, the probability of visible line, the effect of delay spread and fading It is intended to provide a location determination and interworking method.

It provides a method of determining the components of the communication system and the interworking method in consideration of the communication environment in consideration of the communication environment comprising the step of setting the interworking method of the communication environment.

According to the present invention, in providing a ubiquitous mobile communication service, in order to provide a user-centered service in various communication environments, communication system components are arranged in consideration of a communication environment, and the user desires through interworking between the components. You can provide services anytime, anywhere.

In addition, a user-oriented service may be provided by allowing a user to select a communication network and a provided service according to user preference or service efficiency.

The suburban macrocell environment has a high user mobility of 0 ~ 120km / h within a cell radius of less than 2km, and may cause shading and fast fading due to the density of buildings. In addition, the NLOS environment has a high rate of occurrence, long local spreading, and interference between adjacent cells.

4) Rural Macro Cells
