Management device, management method, and terminal device for displaying additional information on image and displaying image

1. A management device comprising:

a determination unit that refers to position information of a terminal device registered in a given base station device to determine ease of connection to another base station device; and

a generator that generates guidance information to prompt the terminal device to move to a position where likelihood of connection to the other base station device is increased, based on a result of determination in the determination unit, wherein

the guidance information generated in the generator is information to display an image in which an image of a scenery around captured in the terminal device is superimposed on the guidance information to prompt the terminal device to move to a position where the likelihood of connection to the other base station device is increased.

2. The management device according to claim 1 , wherein

the guidance information is information indicating a guidance position where the likelihood of connection to the other base station device is increased, a direction from a position of the terminal device toward the guidance information, or a route from the position of the terminal device toward the guidance position.

3. The management device according to claim 2 , wherein

the guidance information is one of a position of the other base station device, a position where communication with the other base station device is enabled, and a position determined by an electric field intensity of the other base station device.

4. A management device comprising:

a determination unit that refers to position information of a terminal device registered in a given base station device to determine ease of connection to another base station device; and

a generator that generates guidance information to prompt the terminal device to move to a position where likelihood of connection to the other base station device is increased, based on a result of determination in the determination unit,

wherein

the given base station device and the other base station device are base station devices in which groups for group communication are registered,

the management device further comprising:

a selection unit that selects, from the groups registered in the given base station device, one or more groups as a subject of a process, wherein

the determination unit determines ease of connection to the other base station device from at least some terminal devices belonging to the group selected by the selection unit, and

the selection unit selects a group for which the number of terminal devices belonging to the group and registered in the other base station device is larger than the number of terminal devices belonging to the group and registered in the given base station device.

5. The management device according to claim 4 , wherein

the guidance information generated in the generator is information to display a map on the terminal device to prompt the terminal device to move to a position where the likelihood of connection to the other base station device is increased, the map showing said position.

6. The management device according to claim 4 , wherein

the guidance information is information indicating a guidance position where the likelihood of connection to the other base station device is increased, a direction from a position of the terminal device toward the guidance information, or a route from the position of the terminal device toward the guidance position.

7. The management device according to claim 6 , wherein

the guidance information is one of a position of the other base station device, a position where communication with the other base station device is enabled, and a position determined by an electric field intensity of the other base station device.

8. A management device comprising:

a determination unit that refers to position information of a terminal device registered in a given base station device to determine ease of connection to another base station device; and

a generator that generates guidance information to prompt the terminal device to move to a position where likelihood of connection to the other base station device is increased, based on a result of determination in the determination unit,

wherein

the given base station device and the other base station device are base station devices in which groups for group communication are registered,

the management device further comprising:

a selection unit that selects, from the groups registered in the given base station device, one or more groups as a subject of a process, wherein

the determination unit determines ease of connection to the other base station device from at least some terminal devices belonging to the group selected by the selection unit, and

the selection unit selects, of a plurality of base station devices forming a communication system, a base station device in which the number of groups registered in the base station device is equal to or larger than a predetermined number or selects a predetermined number of base station devices arranged in the descending order of the number of groups registered in the base station device, and defines one of the base station devices selected as the given base station device.

9. The management device according to claim 8 , wherein

the guidance information generated in the generator is information to display a map on the terminal device to prompt the terminal device to move to a position where the likelihood of connection to the other base station device is increased, the map showing said position.

10. The management device according to claim 8 , wherein

the guidance information is information indicating a guidance position where the likelihood of connection to the other base station device is increased, a direction from a position of the terminal device toward the guidance information, or a route from the position of the terminal device toward the guidance position.

11. The management device according to claim 10 , wherein

the guidance information is one of a position of the other base station device, a position where communication with the other base station device is enabled, and a position determined by an electric field intensity of the other base station device.
