Wireless communication apparatus, wireless communication method, and computer-readable recording medium

1. A wireless communication apparatus comprising:

a memory; and

a processor that is connected to the memory, wherein the processor executes a process including:

specifying, whether or not an application is a limit target application, whose function that can be used by a first communication network cannot be used by a second communication network,

determining, while data is transmitted through both of the first communication network and the second communication network at the same time and wireless communication is executed, the first communication network or the second communication network to be a communication network available for the application specified at the specifying, on the basis of the radio quality of the first communication network, the radio quality of the second communication network, and whether or not the application is the limit target application; and

notifying the application of network information to make the application recognize that the mobile terminal is connected to the available communication network determined at the determining.

2. The wireless communication apparatus according to claim 1 ,

wherein the determining includes, when the radio quality of the first communication network is equal to or greater than a first threshold value and is less than a second threshold value, determining that the first communication network to be the available communication network for an application other than the limit target application specified at the specifying, and determining that the second communication network is the available communication network for the limit target application specified at the specifying, and

transmitting the network information for specifying the first communication network to the application other than the limit target application and transmitting the network information for specifying the second communication network to the limit target application.

3. The wireless communication apparatus according to claim 2 ,

wherein the determining includes, when the radio quality of the first communication network is equal to or greater than the second threshold value, determining that the first communication network is the available communication network for the limit target application, and

the notifying includes transmitting the network information for specifying the first communication network to the limit target application and suppressing the transmission of the network information to the application other than the limit target application.

4. The wireless communication apparatus according to claim 3 ,

wherein the determining includes, when the radio quality of the first communication network is maintained at a level that is equal to or greater than the second threshold value for a predetermined period of time, determining that the first communication network is the available communication network for the limit target application.

5. The wireless communication apparatus according to claim 2 ,

wherein the determining includes, when the radio quality of the first communication network is less than the first threshold value, determining that the second communication network is the available communication network for the limit target application and the application other than the limit target application, and

the notifying includes transmitting the network information for specifying the second communication network to the limit target application and the application other than the limit target application.

6. The wireless communication apparatus according to claim 5 ,

wherein the determining includes, when the radio quality of the first communication network is maintained at a level that is less than the first threshold value for a predetermined period of time, determining that the second communication network is the available communication network for the limit target application and the application other than the limit target application.

7. A wireless communication method comprising:

specifying, whether or not an application is a limit target application, whose function that can be used by a first communication network cannot be used by a second communication network;

determining, while data is transmitted through both of the first communication network and the second communication network at the same time and wireless communication is executed, the first communication network or the second communication network to be a communication network available for the specified application, on the basis of the radio quality of the first communication network, the radio quality of the second communication network, and whether or not the application is the limited target application, and

notifying the application of network information to make the application recognize that the mobile terminal is connected to the determined available communication network.

8. A non-transitory computer-readable recording medium having stored a wireless communication program causing a computer to execute a process comprising:

specifying, whether or not an application is a limit target application, whose function that can be used by a first communication network cannot be used by a second communication network;

determining, while data is transmitted through both of the first communication network and the second communication network at the same time and wireless communication is executed, the first communication network or the second communication network to be a communication network available for the specified application, on the basis of the radio quality of the first communication network, the radio quality of the second communication network, and whether or not the application is the limited target application; and

notifying the application of network information to make the application recognize that the mobile terminal is connected to the determined available communication network.
