Description

Technical Field [0001] The present invention relates to a distributed-active hybrid wobble mobile communication network system and a method for implementing the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a distributed-initiated hybrid WiMAX mobile communication network, and more particularly, to a distributed-active hybrid WiMAX mobile communication network system operating as distributed-active hybrid WiMAX mobile stations and an implementation method thereof.

The existing WiBro mobile communication network is composed of four elements, and includes a user terminal using a WiBro mobile network service, a base station for transmitting information wirelessly, a control station for managing the mobility and session of the terminal, and a backbone Lt; / RTI > servers. In addition, the WiBro base station, the control station and the servers are connected to the backbone by a wired network, and the WiBro mobile communication network is centrally operated by the communication company.

The mobile communication network connected to the wired network has a problem that the function of the mobile communication network can not be normally performed when the wired network connecting the respective components is disconnected due to the cause of the disaster or the like. Therefore, for robust operation in such an environment, the structure of the WiBro mobile communication network should be changed so that the base station operates the single network or operates while connecting the wired mobile communication network components to the wireless communication devices.

Also, in a military environment, there is a need for a method of supporting a mobile communication service to a user terminal operating together with a base station by necessity of a military operation or the like. In addition, when the mobile station is stationary, the sector antenna is installed on the ground to increase the communication capacity, or the communication capacity is reduced using the omnidirectional antenna during start-up, but the mobility is provided. In the shadow area, A complex method is needed.

In addition, since the mobile base stations operate differently, there is a need for a method in which a handover function between mobile stations is provided to a user terminal while a cell plan is established in a distributed manner and a mobile communication network plan is operated.

The user terminal uses a base station ID (Base Station ID) transmitted from the base station to uniquely identify the base station. The base station identifier is composed of 48 bits (bits). The upper 24 bits of the base station identifier are used as a carrier identifier (Operator ID). The lower 24 bits of the base station identifier are a programmable field and are defined by the operator and used to identify the equipment.

In order for the user terminal to perform handover between the base stations, the same carrier identifier must be used in the WiBro. Therefore, the device identifier of the distributed-active hybrid WiMAX mobile station should be established so as to accommodate various network formation modes of the mobile station, various types of distributed mobile station operators, and various complex antennas, thereby effectively operating the distributed-active hybrid WiMAX mobile communication network .
