(Description of operation of second embodiment)
Next, the operation of radio terminal 100 according to the present embodiment will be described in detail with reference to the drawings.

First, the operation of the wireless terminal 100 when a pairing operation between terminals is detected will be described using the flowchart of FIG.

Referring to FIG. 4, first, the pairing detection means 14 detects a pairing operation between the wireless terminal 100 and the counterpart terminal (step S401). The pairing detection means 14 detects a pairing operation by detecting a beacon transmitted by the partner terminal when the terminal is the pairing receiver. When the own terminal becomes the pairing transmission side, the pairing detection unit 14 detects the pairing operation by detecting a reply of the local communication ID of the partner terminal to the beacon of the own terminal.

Next, the connection establishment means 15 performs pairing between terminals (step S402).

In parallel with the processing of the connection establishing means 15, the target terminal specifying means 16 specifies the address of another path that has been connected to the partner terminal (step S403).

When the target terminal identification unit 16 identifies the address of the other route, the target terminal identification unit 16 transmits a pairing completion notification to the application 10 (step S404). Actually, the pairing operation between the terminals is continuing to be executed by the connection establishing unit 15 at this time, but the target terminal specifying unit 16 performs the pairing for the application 10 when the address of the other route can be specified. Notification is made assuming that is completed.

Next, the application 10 that has received the notification starts communication (step S405).

Next, the communication identification unit 11 detects the occurrence of communication by the application 10 and identifies that the communication is data communication of the application 10 (step S406). Then, the communication identification unit 11 inquires of the connection control unit 12 which route is used for communication (step S407).

Upon receiving the inquiry, the connection control means 12 uses the NW state monitoring means 17 to check the status of each route (step S408). At this time, the NW state monitoring unit 17 confirms that the direct communication path side has not yet been connected, and that the other path is already connected. Therefore, the connection control unit 12 instructs the route changing unit 13 to transmit the data communication of the application 10 using another connected route (step S409). Thereby, communication of the application 10 is started prior to establishment of pairing.

Thereafter, when the NW state monitoring unit 17 confirms the establishment of pairing (step S410 “YES”), the connection control unit 12 instructs the route changing unit 13 to perform data communication of the application 10 through a direct communication route. (Step S411). Receiving the instruction, the route changing means 13 performs data communication of the application 10 using the direct communication route (step S412).

Next, the communication identification unit 11 identifies the communication assuming direct communication with the pairing target terminal, and inquires of the connection control unit 12 about the communication path (step S503). Here, the communication identification unit 11 acquires the local communication ID (Bluetooth ID, Wi-Fi SSID, etc.) of the pairing target terminal of the communication destination.

The connection control means 12 that has received the inquiry confirms the status of the NW IF using the NW status monitoring means 17 (step S504). Since the direct communication path is not established at this time, the connection control unit 12 instructs the path changing unit 13 to perform communication of the application 10 through another connected communication path (step S505).

Upon receiving the instruction, the path changing unit 13 specifies the communication destination address in the other communication path using the target terminal specifying unit 16 and performs control so that the communication of the application 10 is performed in the other connected communication path (step). S506). Thereby, communication of the application 10 is started prior to establishment of pairing.

The connection control unit 12 instructs the route change unit 13 while instructing the connection establishment unit 15 to establish pairing communication (step S507). The connection establishment unit 15 performs pairing processing on the local communication ID acquired by the communication identification unit 11 (step S508).

Thereafter, when the NW state monitoring unit 17 confirms the establishment of the direct communication path (step S509 “YES”), the connection control unit 12 performs the path change unit so that the data communication of the application 10 is performed using the direct communication path. 13 is instructed (step S510). Receiving the instruction, the path changing unit 13 performs data communication of the application 10 using the direct communication path (step S511).

Next, the operation shown in FIG. 4 will be described using a specific embodiment.

Since the details of the OpenFlow technology are disclosed in Patent Document 2, detailed descriptions of the OpenFlow switch 110 and the OpenFlow controller 111 are omitted. According to the technique using OpenFlow, a plurality of RATs can be connected at the same time, and which RAT is used can be selectively controlled depending on the communication type.

In addition, the wireless terminal 100 according to the present embodiment has an NW IF used for two routes of 3G and Bluetooth. In an initial state, 3G is connected and Bluetooth is not connected.

(Description of operation)
The operation of the present embodiment will be described using the flowchart of FIG.

First, the pairing detection means 14 detects the Bluetooth pairing operation between the wireless terminal 100 and the counterpart terminal (step S601). The pairing detection means 14 detects a pairing operation by detecting a beacon transmitted by the partner terminal when the terminal is the pairing receiver. When the own terminal becomes the pairing transmission side, the pairing detection unit 14 detects the pairing operation by detecting a reply of the other party's Bluetooth ID to the beacon of the own terminal.

Next, the connection establishment means 15 performs a Bluetooth connection process between terminals (step S602).

In parallel with the processing of the connection establishment unit 15, the target terminal identification unit 16 identifies a communication destination address in 3G that is already connected to the partner terminal (step S603).

When the target terminal identification unit 16 identifies the communication destination address, the target terminal identification unit 16 transmits a pairing completion notification to the application 10 (step S604). Actually, the Bluetooth connection process is being continuously executed by the connection establishing unit 15 at this point, but the target terminal specifying unit 16 is paired with the application 10 when the 3G communication destination address can be specified. A notification is given on the assumption that it has been completed.

Next, the application 10 that has received the notification starts data communication by 3G (step S605).

Next, the OpenFlow switch 110 detects the occurrence of communication by the application 10, and identifies that the communication performed by the wireless terminal 100 is data communication of the application 10 (step S606). Then, the OpenFlow switch 110 inquires the OpenFlow controller 111 which route is used for communication (step S607).

The OpenFlow controller 111 that has received the inquiry confirms the state of each path by using the NW state monitoring unit 17 (step S608). The NW state monitoring means 17 confirms that the connection has not yet been established for Bluetooth and that the 3G is already connected. Therefore, the OpenFlow controller 111 instructs the OpenFlow switch 110 to transmit the data communication of the application 10 using 3G (step S609). Thereby, communication of the application 10 is started prior to establishment of Bluetooth.

Thereafter, when the NW state monitoring unit 17 confirms the establishment of the Bluetooth (Step S610), the OpenFlow controller 111 instructs the OpenFlow switch 110 to perform data communication of the application 10 using Bluetooth (Step S611). Upon receiving the instruction, the OpenFlow switch 110 performs data communication of the application 10 using Bluetooth (step S612).

Next, the operation shown in FIG. 5 will be described using a specific embodiment.

(Description of configuration)
The configuration of this embodiment is the configuration shown in FIG. Also, in this embodiment, the network has two path NW IFs of 3G and Bluetooth. In the initial state, 3G is connected and Bluetooth is not connected.

(Description of operation)

Referring to FIG. 7, first, the application 10 starts communication (step S701). At this point, Bluetooth has not been established, and no connection establishment operation has been performed.

The OpenFlow switch 110 detects the occurrence of communication of the application 10 (step S702). Next, the OpenFlow switch 110 identifies that the communication is assumed to be Bluetooth communication to the pairing target terminal, and inquires of the OpenFlow controller 111 about the communication path (step S703). Here, the OpenFlow switch 110 acquires the Bluetooth ID of the pairing target terminal of the communication destination.

Upon receiving the inquiry, the OpenFlow controller 111 confirms the state of the NW IF using the NW state monitoring unit 17 (step S704). Since Bluetooth has not been established at this time, the OpenFlow controller 111 instructs the OpenFlow switch 110 to perform communication of the application 10 with 3G (step S705).

Upon receiving the instruction, the OpenFlow switch 110 specifies the communication destination address in 3G using the target terminal specifying means 16 and controls the application 10 to perform communication in 3G (step S706). Thereby, communication of the application 10 is started prior to establishment of pairing.

The OpenFlow controller 111 instructs the OpenFlow switch 110, while instructing the connection establishment means 15 to establish Bluetooth communication (step S707). The connection establishment unit 15 performs pairing processing on the Bluetooth ID acquired by the OpenFlow switch 110 (step S708).

Thereafter, when the NW state monitoring unit 17 confirms the establishment of the Bluetooth communication (step S709 “YES”), the OpenFlow controller 111 instructs the OpenFlow switch 110 to perform data communication of the application 10 using the Bluetooth (step S710). ). Upon receiving the instruction, the OpenFlow switch 110 performs data communication of the application 10 using Bluetooth (step S711).

(Effects of the second embodiment)
The wireless terminal 100 according to the present embodiment starts the pairing establishment process triggered by the detection of the pairing operation or the communication of the application 10, and in parallel with this, starts data transmission on another route, and the pairing is established. At that point, the communication path is changed to a direct communication path. Therefore, according to the wireless terminal 100 of the present embodiment, the communication time can be reduced as compared with the case where data communication is started after the establishment of pairing.
