The radio resource information management unit 220 may store and manage radio resource information exchanged with the base station 100 in the course of communication with the base station 100 , and the radio management information is the base station 100 while the autonomous navigation devices 20 move along the movement path. ), and this information contains information about the communication environment, such as whether the wireless channel is unstable and scattering, and the information is transmitted to the server 200 through the base station 100 to provide a real-time map of the communication environment. It can be used when updating to .

The communication path storage unit 230 may receive and store optimal communication path information between the base stations themselves and the autonomous navigation devices 20 from the server 200 .

A communication path is determined so that a communication channel between the autonomous driving device 20 and the base station 100 is optimally formed, and information on the determined communication path is transmitted to corresponding base stations in a communication environment through which the moving path passes.

Accordingly, the wireless communication device 10 may provide an optimal communication path to the autonomous driving device 20 by identifying the state of the entire communication environment based on the communication environment map updated in real time.

4 is a flowchart illustrating a method of a wireless communication device setting up a communication path and allocating radio resources according to an embodiment of the present invention.

First, when the autonomous driving device 20 receives a destination from the current location, it sets a movement route and stores it in the internal location storage unit 24 ( S401 ), and then stores the current location information and the set movement route information in the base station 100 . ) through the server 200 (S403).

Next, the server 200 constructs a map for the communication environment of each base station 100 , maps the communication environment map to the movement path of the autonomous driving device 20 ( S405 ), and then An optimal communication path for the autonomous driving device 20 moving along the movement path within the communication range is determined (S407).

Next, the server 200 determines whether it is possible to set the determined optimal communication path (S409), and if it is determined that it is not possible, requests the autonomous driving device 20 to set the movement path again through the base station 100 and (S401), if it is determined that it is possible, the communication path according to the set movement path is transmitted to the base station 100 for storage, and also stored in the server 100 (S411).

As a next operation, the base station 100 establishes a communication path with the autonomous navigation device 20 based on the communication path information received from the server 200 , and allocates radio resources to perform communication. A communication path setting and radio resource allocation process between the base station 100 and the autonomous navigation device 20 will be described in detail below with reference to FIG. 5 .

5 is a flowchart illustrating a method for setting an optimal communication path based on a moving path and allocating radio resources by a wireless communication device according to an embodiment of the present invention.

First, while the autonomous driving device 20 is moving to a destination along a set movement path ( S501 ), the base station 100 communicating with the autonomous driving device 20 uses a communication path preset in the server 200 . A communication path is set based on the communication path, and radio resources are allocated to the set communication path (S503). At this time, the base station 100 collects radio resource information, analyzes the communication environment, and updates the communication environment map.

Next, the base station 100 sets the communication path with the autonomous navigation device 20 in an optimal state based on the new communication path information received from the server 200 and determines whether radio resource allocation is possible (S505). When it is determined that the optimal communication path setting and radio resource allocation are impossible, the base station 100 transmits the obtained radio resource information to the server 200 and receives the communication path information determined according to the updated communication environment map from the server 200 . do (S513). That is, the base station 100 resets the communication path according to the current communication environment map.

Next, the base station 100 communicates with the autonomous navigation device 20 according to the set communication path and the allocated radio resource (S507).

Next, the base station 100 acquires radio resource information based on the currently set communication path and the allocated radio resource and transmits it to the server 200 (S509).

Next, the server 200 updates the communication environment map based on the radio resource information received from the base station 100 (S511).

For example, when the autonomous driving device 20 transmits initially set movement path information to the server 200 through the base station 100, the server 200 provides a map of the communication environment of the base stations 100 on the movement path. It maps to the movement path to determine the optimal communication path. Next, when the server 200 provides communication path information to each base station 100 , the base station 100 establishes a communication path with the autonomous navigation device 20 according to the communication path information provided from the server 200 . and allocating radio resources to attempt communication. However, when a change in the environment occurs within the communication environment and a communication failure such as an unstable situation of a wireless channel or scattering occurs, stable communication between the base station 100 and the autonomous navigation device 20 is not achieved. Accordingly, the base station 100 acquires changes in the communication environment or radio resource information during communication with the autonomous driving device 20 and transmits it to the server 200, and the server 200 updates the communication environment map using this information. Therefore, the latest communication environment map is always stored. Next, the server 200 maps the latest communication environment map and the moving path of the autonomous driving device 20 , and re-determines a communication path for optimal communication with the autonomous driving device 20 . However, when it is determined that the determined communication path cannot be set, the server 200 may cause the autonomous driving device 20 to re-establish the moving path and map the new moving path to the communication environment map to determine the communication path again. have. Accordingly, since the autonomous driving device 20 can receive radio resources according to the optimal communication path from the base stations 100 while moving to the destination, and thus can always stably communicate with the base station 100, the present invention The wireless communication device 10 according to the embodiment can provide an autonomous driving device with a fast communication connection, stable communication quality, and a high level of communication service.
