the first terminal;

the first network;

the second network;

a second terminal including the first communication module owned by the user; and

a third terminal including the second communication module owned by the user.

6 . The communication device according to claim 2 , wherein

the type of the communication information is a degree of importance or a degree of urgency.

7 . The communication device according to claim 1 , wherein

the at least one processor

monitors both of a connection state between the first network and the first communication module and a connection state between the second network and the second communication module,

selects the first network when the first communication module is in a state of being connected to the first network and the second communication module is in a state of being not connected to the second network, and

selects the second network when the first communication module is in a state of being not connected to the first network and the second communication module is in a state of being connected to the second network.

8 . The communication device according to claim 7 , further comprising:

a storage unit configured to store any one of first setting and second setting in association with the user, wherein

the at least one processor

selects, when the first setting is associated with the user, only one of the first network and the second network, and

selects, when the second setting is associated with the user, both of the first network and the second network.

9 . The communication device according to claim 8 , wherein the at least one processor

manages first location information indicating a location of the first communication module and second location information indicating a location of the second communication module; and

acquires, based on the first location information and the second location information, a distance between the first communication module and the second communication module, and

determines, according to the distance, whether the first setting is applied or the second setting is applied to the user.

10 . A communication system comprising:

the communication device according to claim 7 ;

the first terminal;

the first network;

the second network;

a second terminal including the first communication module owned by the user; and

a third terminal including the second communication module owned by the user.

11 . The communication device according to claim 1 , further comprising

a storage unit configured to store any one of first setting and second setting in association with the user, wherein

the at least one processor

selects, when the first setting is associated with the user, only one of the first network and the second network, and

selects, when the second setting is associated with the user, both of the first network and the second network.

12 . The communication device according to claim 11 , wherein the at least one processor

manages first location information indicating a location of the first communication module and second location information indicating a location of the second communication module; and

acquires, based on the first location information and the second location information, a distance between the first communication module and the second communication module, and

determines, according to the distance, whether the first setting is applied or the second setting is applied to the user.

13 . A communication system comprising:

the communication device according to claim 1 ;

the first terminal;

the first network;

the second network;

a second terminal including the first communication module owned by the user; and

a third terminal including the second communication module owned by the user.

14 . The communication device according to claim 1 , wherein

the type of the user is an official position of the user in an organization.

15 . A communication method comprising:

receiving, from a first terminal, communication information including identification information of a user to be a destination;

comparing a first priority set for a first network to which a first communication module associated with the user is connectable with a second priority set for a second network to which a second communication module associated with the user is connectable, the second network being different from the first network;

selecting, based on the identification information, a network having a higher priority among the first network and the second network, the first priority and the second priority being set according to a type of the user; and

transmitting, via the selected network, information related to the communication information to a communication module connectable to the selected network among the first communication module and the second communication module.
