User information, such as) is transmitted from the mobile communication terminal 110 to the base node (100, 102) through the distributed nodes (104, 106, 108). Then, the organic topology manager 112 reflects the moving speed of the mobile communication terminal 110, and thus the beam angle and width that are most suitable for wireless data transmission and reception between the mobile communication terminal 110 and the distributed nodes 104, 106, and 108. ), Power, etc. are calculated, and the calculated information is provided to the node nodes 100 and 102.

At this time, the organic topology manager 112 connected to the base node 102 analyzes information such as the speed of the mobile communication terminal 114 or the location of the mobile communication terminal 114, and is moving the path requiring high-speed movement. The terminal 114 does not go through the distributed nodes 104, 106, and 108, and performs handover only on the base node 102, thereby supporting high-speed mobility of the mobile communication terminal 114.

Accordingly, in the node node 102, unlike the conventional mobile communication terminal 110 moving at a low speed, the mobile communication terminal 114 performs a handover only between the node nodes for the mobile communication terminal 114 moving at a high speed. 114) to support mobility.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1, 4, and 5.

First, the user information such as the moving speed, location, direction information, service type, battery information, and the like of the mobile communication terminal 110 is transmitted from the mobile communication terminal 114 to the base node 102 (S500).

Accordingly, in the organic topology manager 112 connected to the base node 102, the beam angle, width, power, etc., which are most suitable for transmitting and receiving wireless data with the mobile communication terminal 114 by reflecting the moving speed of the mobile communication terminal 114 are determined. The calculated information is provided to the base node 102.

Then, the base node 102 determines beam related information such as beam angle, width, power, and feedback period calculated from the organic topology manager 112 as described above (S502), and performs mobile communication with the determined beam angle, width, and power. The wireless communication path with the terminal 114 is set to transmit data such as feedback period information to the mobile communication terminal 114 (S504).

Subsequently, when the entire user information feedback period is reached, the mobile communication terminal 114 returns to the base node 102, and the entire user, such as the moving speed, location, and direction information of the mobile communication terminal 114, service type, and battery information. The information is fed back and transmitted (S506).

Then, the base node 102 again reflects the movement speed of the mobile communication terminal 114 included in the entire user information, and the beam angle most suitable for wireless data transmission and reception between the mobile communication terminal 114 and the base node 102, Beam-related information such as width and power is determined (S508), and a wireless communication path is set with the mobile communication terminal 114 at the determined beam angle, width, and power to transmit data such as feedback period information to the mobile communication terminal 114. It transmits (S510).

On the other hand, in this case, when handover is required as the mobile communication terminal 114 moves, the node node 102 analyzes information such as the speed or the location of the mobile communication terminal 114 to determine a path for which high speed movement is required. When moving, the mobile communication terminal 114 is determined to be a high-speed mobile communication terminal. Accordingly, the base node 102 uses only the base nodes 100 and 102 for the mobile communication terminal 114. Handover is supported to support mobility according to high speed movement of the mobile communication terminal 114.

That is, the base node 102 is a handover between node nodes to a new node node 100 to be moved by the mobile terminal 114, the high-speed movement, if a handover is required according to the high-speed movement of the mobile communication terminal 114 Request for over (S510), and transmits the entire user information for handover (S512).

Then, in the node node 100 to which the mobile communication terminal 114 is to be moved, the mobile node 114 and the base node 100 reflect the movement speed of the mobile communication terminal 114 included in the entire user information. Beam related information such as beam angle, width and power and feedback period information, which are most suitable for wireless data transmission and reception, are determined (S514), and the wireless communication path with the mobile communication terminal 114 is determined using the beam angle, width and power determined as described above. Set and transmit data such as feedback period information to the mobile communication terminal (114) (S516).

Although the mobile terminal 110 transmits a user mobility support request to a new distributed node 104 where the mobile terminal 110 moves and is located without a load analysis process, the handover for the mobile terminal 110 may be performed. In this conventional method, as shown in FIG. 7, a plurality of mobile communication terminals are already connected to the distributed node 104 to which the mobile communication terminal 110 is newly connected through handover, and thus the network load is high. In this case, there is a problem in that the reliability of the wireless access service cannot be secured.

Accordingly, in the present invention, each distributed node 104, 106 for a distributed node 106 where the mobile communication terminal 110 is currently located and a new distributed node 104 where the mobile communication terminal 110 will be moved and located. After performing load analysis based on the handover using the provided load information, if the load is high even in a distributed node having a relatively high signal strength, the mobility support is continuously performed at a distributed node having a relatively low load.

When approaching, node node 102 analyzes the load of the current distributed node 106 and the new distributed node 104, and then, if the load of the new distributed node 104 is higher than the reference, the new distributed node ( Instead of performing a handover to 104, the mobile communication terminal 110 requests the user's movement support to the distributed node 106 where the mobile terminal 110 is currently located so that the current distributed node 106 has a low signal strength but relatively high load. Continues to control the connection with the mobile communication terminal (110).
