Abstract

A mobile terminal measures a first wireless quality that is a wireless quality of a first communication network, and measures a second wireless quality that is a wireless quality of a second communication network. The mobile terminal then determines a ratio between the number of first sockets used for the first communication network and the number of second sockets used for the second communication network, based on the first wireless quality or the second wireless quality. The mobile terminal then generates the first sockets and the second sockets at the determined ratio and transmits data by using each of the generated sockets.

Claims

1. A wireless communication apparatus, comprising:

a memory, and

a processor connected to the memory wherein the processor executes a process comprising;

first measuring a first wireless quality that is a wireless quality of a first communication network;

second measuring a second wireless quality that is a wireless quality of a second communication network;

determining a ratio between the number of first sockets used for the first communication network and the number of second sockets used for the second communication network, based on the first wireless quality or the second wireless quality; and

generating the first sockets and the second sockets at the ratio determined at the determining and transmitting data by using each of the generated sockets.

2. The wireless communication apparatus according to claim 1, wherein

the first measuring includes calculating, in each application, average throughputs of the first communication network when a predetermined number of data sets are transmitted,

the second measuring includes calculating, in each application, average throughputs of the second communication network when a predetermined number of data sets are transmitted, and

the determining includes increasing the number of the first sockets from previous number when the average throughput of the first communication network, which is higher in speed than the second communication network, is improved from a previous average throughput, and decreasing the number of the second sockets from previous number.

3. The wireless communication apparatus according to claim 2, wherein, when the average throughput of the first communication network is reduced from the previous average throughput, the determining includes decreasing the number of the first sockets from the previous number and increasing the number of the second sockets from the previous number.

4. The wireless communication apparatus according to claim 1, wherein the process further comprises retransmitting, when a communication error occurs in data transmission using the first sockets or the second sockets, data which is transmitted in the data transmission in which the communication error occurred using sockets of the communication network different from the communication network used at occurrence of the communication error.

5. The wireless communication apparatus according to claim 1, wherein the process further comprises transmitting, when transmission of data having a specified volume or more is performed by using the first sockets or the second sockets, subsequent data by using the sockets of the communication network different from the communication network used in transmission of the data having the specified volume or more until the transmission of the data having the specified volume or more is completed.

6. A wireless communication method comprising:

measuring a first wireless quality that is a wireless quality of a first communication network, using a processor;

measuring a second wireless quality that is a wireless quality of a second communication network, using the processor;

determining a ratio between the number of first sockets used for the first communication network and the number of second sockets used for the second communication network, based on the first wireless quality or the second wireless quality, using the processor; and

generating the first sockets and the second sockets at the determined ratio and transmitting data by using each of the generated sockets, using the processor.

7. A computer-readable recording medium having stored therein a wireless communication program causing a computer to execute a process comprising:

measuring a first wireless quality that is a wireless quality of a first communication network;

measuring a second wireless quality that is a wireless quality of a second communication network;

determining a ratio between the number of first sockets used for the first communication network and the number of second sockets used for the second communication network, based on the first wireless quality or the second wireless quality; and

generating the first sockets and the second sockets at the determined ratio and transmitting data by using each of the generated sockets.
