The terminal changes the signal level received in step 305 to color and displays it on the map. (For example, shaded area: red, serviceable area: green)

4 is a flowchart illustrating a route search method in a tactical information communication network according to another embodiment of the present invention.

In particular, FIG. 4 is a flowchart of an operation from a server point of view.

In step 401, the server receives signal information related to neighboring base stations of the terminal.

The server checks the location of the terminal in step 403. The location of the terminal can be confirmed through GPS (Global Positioning System) location information of the terminal. In step 405, the server extracts the signal level around the terminal from the average signal level table in the server and transmits it to the terminal. The average signal level table will be described with reference to FIG. 6 to be described later.

5 is a flowchart illustrating a route search method in a terminal, a base station, and a server according to an embodiment of the present invention.

In step 501, the terminal attempts to access the communication network to the base station. At this time, the terminal checks the signal level of the neighboring base station through a communication network connection, connects to the base station with the best (or highest) signal level, and displays the base station signal level at the current location of the terminal.

The base station provides a communication service to the terminal in response to the terminal's attempt to access the communication network in step 503.

Thereafter, in step 505, the server periodically stores the location information and signal level of the terminal in the server, and informs the terminal of the result when requested by the terminal.

The server periodically collects location information and signal level of an area where the terminal is being used. The server stores the collected information in a database in the server and stores the signal level for each location of the terminal, and manages/stores/updates the real-time signal level and the average signal level as shown in FIG. 6.

6 is an exemplary diagram of a database in a server according to an embodiment of the present invention.

The server, for example, location information (GPS: 52SCG11112222) (613), signal level (RSSI: -95, CINR: 5) (615), collection time (2019-01-01 10:00) (617) of terminal 1 (601) ) To manage/save/update.

The server also collects location information, signal level, and collection time in the terminal 2 603 and terminal 3 605 and manages/stores/updates it in the database 607.

In an embodiment of the present invention, the database 607 manages/stores/updates the real-time signal level, as shown by reference numeral 609.

For example, location information, RSSI value, and CINR value collected at collection time 2019-01-01 10:10 are managed/stored/updated, and location information, RSSI value, CINR value collected at 2019-01-01 10:00 Manage/save/update files.

In another embodiment of the present invention, the database 607 manages/stores/updates the average signal level, as shown by reference number 611.

For example, the average RSSI value -82.5 and the average CINR value 12.5 corresponding to the location information 52SCG11112222 are managed/stored/updated, and the average RSSI value -50 and the average CINR value 35 corresponding to the location information 52SCG11112225 are managed/stored/updated.

7 and 8 show exemplary diagrams of route search according to options according to an embodiment of the present invention.

When requesting a route from the terminal to the route guidance application, it can be executed with two options, such as short-distance or shaded area bypass, and the route presented after route search is presented as multi-path by giving priority instead of one.

The priority may be determined based on the signal level, for example.

If the user selects the short distance option, the route search is performed in a general route search method as shown in 701 of FIG. 7. In the case of FIG. 7, it is impossible to confirm the shadow areas 703 and 705 in the path, and the path is presented after the path search without considering the shadow areas 703 and 705.

However, when the user selects the shaded area bypass option, route search is performed in the order of superior signal level by combining a real-time signal level table for each location (based on GPS) in the route searched for short distance search, as shown in 801 and 803 of FIG. Show a list (multiple paths). In the case of FIG. 8, a path is presented by adding a shaded area bypass 803 or a minimum shaded area 805 in the path. At this time, the terminal displays a warning message so that the user can recognize the fact of the shadow area in advance.

As an additional embodiment, routes that increase over a certain distance are guided to a route that passes through a minimum shaded area except for the search target, but a warning message is displayed on the terminal so that the user can recognize the fact of the shaded area in advance. do.

9 is an exemplary diagram of a route search according to another embodiment of the present invention.

If the terminal 901 is already located in the shaded area, the detour route service shown in FIG. 8 cannot be used. In order to solve this problem, the map application of the terminal periodically requests signal level information within a few kilometers of the terminal reference radius from the server when connected to the base station. In response to the request, the server transmits the average signal level information in the database to the terminal, and the terminal displays a color corresponding to the signal level on the map application. (For example, shaded area: red, serviceable area: green)

The signal level information displayed on the map is stored in the terminal until a response from the additional request from the terminal is received, and can be checked after executing the application regardless of whether the terminal is rebooted or subscribed to the service. Even when the terminal is not connected to the base station, the user can check the signal level through the map application and determine a moving path for accessing the base station.

Referring to FIG. 9, a user may display a current location of a terminal as shown by reference number 901 and determine a moving direction by referring to a color displayed on a map.

In the present invention, when a user in an area in which a shaded area exists and moves using the terminal, it is possible to maintain a normal operating state of the terminal by guiding only to a communication available area as much as possible through a road guidance service.

In the present invention, since the signal level around the user can be easily checked in the map application of the terminal, it can be a moving path selection criterion.

The present invention can be operated as a terminal management system from a manager's point of view by expanding the system to additionally collect terminal information.

The above contents may be modified and modified without departing from the essential characteristics of the present invention by those of ordinary skill in the art to which the present invention pertains.
