[Outline of mobile terminal 1]
FIG. 1 is a diagram illustrating an outline of the mobile terminal 1 according to the first embodiment. The mobile terminal 1 is a terminal that can be connected to an access point 2 related to a wireless communication network, and is, for example, a mobile phone such as a smartphone. Here, the wireless communication network is, for example, a mobile phone line, a wireless LAN line, a WiMAX (registered trademark) line, or the like. There are a plurality of access points 2 (for example, access points 2A,... 2X, 2Y, etc.) corresponding to each of a plurality of types of wireless communication networks. The access point 2 is connected to a communication network 3 such as the Internet via a wireless communication network that it supports. In the figure, the access point is omitted and also expressed as “AP”.

  When the portable terminal 1 is connected to the access point 2, it stores a connection history with the access point 2 (for example, the access point 2A) (FIG. 1A). When the mobile terminal 1 detects the access point 2 (for example, the access points 2X and 2Y), it detects a plurality of detected access points based on the connection history corresponding to the access point 2 (for example, the access point 2A) connected in the past. The access point 2 to be connected is selected from 2 and communication connection is established with the selected access point 2 (FIG. 1B). Here, the mobile terminal 1 selects the access point 2 to be connected using the connection history of another access point 2 different from the detected access point 2 as the connection history corresponding to the access point 2 connected in the past. .

  FIG. 2 is a diagram illustrating an example in which the mobile terminal 1 according to the first embodiment switches the access point 2. For example, as shown in FIG. 2A, it is assumed that the mobile terminal 1 is connected to the access point 2A that is restricted by the communication amount, the connection time, and the like, and stores the communication history of the access point 2A. Thereafter, when the user of the mobile terminal 1 moves, the mobile terminal 1 is provided in the store as the access point 2 to which the mobile terminal 1 has not been connected in the past while the mobile terminal 1 is connected to the access point 2A. It is assumed that an access point 2B that has no communication restriction, such as a free access point, is newly detected.

  In this case, the mobile terminal 1 determines whether or not to connect to the access point 2B based on the communication amount and connection time included in the communication history of the access point 2A. For example, the mobile terminal 1 exceeds the threshold value indicating that the communication amount or connection time within a predetermined period included in the communication history of the access point 2A is approaching the communication amount or connection time allowed within the predetermined period. If so, it is determined to connect to the access point 2B. When it is determined that the mobile terminal 1 is connected to the access point 2B, the mobile terminal 1 disconnects the communication connection with the access point 2A and connects to the access point 2B. By doing so, the mobile terminal 1 can appropriately determine whether or not to connect to the access point 2 when a new access point 2 is detected.

[Configuration example of mobile terminal 1]
Next, the configuration of the mobile terminal 1 will be described. FIG. 3 is a diagram illustrating a configuration of the mobile terminal 1 according to the first embodiment.

  The wireless unit 11 modulates the signal output from the control unit 13 to generate an RF (Radio Frequency) signal, and wirelessly transmits the RF signal to the access point 2 via an antenna (not shown). The radio unit 11 demodulates the RF signal received from the access point 2 via the antenna, and outputs a signal obtained by the demodulation to the control unit 13. In the following description, it is assumed that the mobile terminal 1 communicates with the access point 2 via the wireless unit 11.

  The storage unit 12 is configured by, for example, a ROM and a RAM. The storage unit 12 stores various programs for causing the mobile terminal 1 to function. For example, the storage unit 12 stores a connection program for causing the control unit 13 of the mobile terminal 1 to function as a detection unit 131, a selection unit 132, and a connection unit 133, which will be described later. The storage unit 12 may read and store a program stored in a storage medium such as an external memory, or may store a program downloaded from an external device via the access point 2 and the communication network 3.

  In addition, the storage unit 12 stores connection history information indicating a connection history between the mobile terminal 1 and the access point 2 corresponding to each of the plurality of access points 2. FIG. 4 is a diagram illustrating an example of information included in the connection history information. As shown in FIG. 4, the connection history information includes a network type, a MAC address, a connection start time, a connection end time, a continuous connection time, a total connection time, a data transmission amount, and a data reception amount. And a MAC address (client).

  The network type is information indicating the type of the wireless communication network corresponding to the access point 2. In the network type, when the type of the wireless communication network is a predetermined type such as a wireless LAN, identification information (for example, SSID) for identifying the access point 2 is stored. The MAC address indicates the MAC address of the access point 2.

  The connection start time indicates the connection start time when the mobile terminal 1 is finally connected for communication with the access point 2. The connection end time indicates the connection end time when the mobile terminal 1 is finally connected for communication with the access point 2 corresponding to the connection history information. The continuous connection time indicates a connection time from when communication connection to the access point 2 is started until communication is disconnected when the mobile terminal 1 is finally connected to the access point 2 for communication. The continuous connection time indicates the connection time from the start of communication connection to the access point 2 to the current time when the access point 2 and the mobile terminal 1 maintain communication connection.

  The total connection time indicates a time during which communication connection with the access point 2 was established within a predetermined period (for example, for one month). The data transmission amount indicates the amount of data transmitted to the access point 2 during a predetermined period. The data reception amount indicates the amount of data received from the access point 2 during a predetermined period. The MAC address (client) indicates the MAC address of the other terminal when the mobile terminal 1 communicates with one or more other terminals by the tethering function provided by itself.

  The control part 13 is comprised by CPU, for example. The control unit 13 controls functions related to the mobile terminal 1 by executing various programs stored in the storage unit 12. The control unit 13 includes a detection unit 131, a selection unit 132, and a connection unit 133.

  The detection unit 131 detects the access point 2. For example, the detecting unit 131 exists within a range where the mobile terminal 1 can communicate by receiving a beacon signal for detecting the access point 2 periodically transmitted from the access point 2 via the wireless unit 11. Access point 2 is detected.

  The selection unit 132 selects the access point 2 to be connected from the plurality of access points 2 detected by the detection unit 131 based on the connection history corresponding to the access point 2 to which the mobile terminal 1 has connected in the past.

  Specifically, when the detection unit 131 newly detects the access point 2, the selection unit 132 detects the newly detected access point based on the connection history corresponding to the access point 2 to which the mobile terminal 1 has connected in the past. 2 is selected, and the access point 2 is selected according to the determination that the access point 2 is newly connected.

  For example, the selection unit 132 selects the access point 2 to be connected based on various information included in the connection history. Hereinafter, a plurality of methods by which the selection unit 132 selects the access point 2 will be described.

[Select access point based on traffic]
The selection unit 132 refers to the connection history, and selects the access point 2 to be connected based on the communication amount with the access point 2 corresponding to the wireless communication network in which communication restriction is performed based on the communication amount within a predetermined period. .

  Specifically, when the detection unit 131 newly detects the access point 2B in a state where the selection unit 132 is in communication connection with the access point 2A, the selection unit 132 checks the network type corresponding to the access point 2A. It is determined whether or not the point 2A is an access point subject to communication restriction based on the traffic. Here, the communication restriction indicates that the communication speed is restricted, for example. In addition, the access point to which communication restriction is applied is an access point corresponding to a pay network line whose network type is, for example, a mobile phone line or a WiMAX line. An access point that is not subject to communication restrictions is, for example, a free access point such as a wireless LAN line provided by a store or an individual.

  When the selection unit 132 determines that the access point 2A is an access point to which communication is restricted based on the communication amount, the data reception amount included in the communication history information of the access point 2A stored in the storage unit 12 is It is determined whether or not the first threshold is exceeded. When the selection unit 132 determines that the data reception amount corresponding to the access point 2A exceeds the first threshold, the selection unit 132 selects the access point 2B as the access point 2 to be connected. By doing in this way, the portable terminal 1 can change a connection destination so that the communication amount via a wireless communication network may not exceed the communication amount which requires a communication restriction.

  Note that the first threshold value is a value (eg, 6.5 GB) determined based on a communication restriction reference value (eg, 7 GB). The selection unit 132 determines whether or not the data reception amount exceeds the first threshold. However, the selection unit 132 is not limited to this, and whether or not the sum of the data reception amount and the data transmission amount exceeds the first threshold. It may be determined.

  The selection unit 132 also determines whether or not the access point 2B is an access point that is subject to communication restriction based on the traffic, and determines whether or not to connect to the access point 2B based on the determination result. You may make it do. For example, when the selection unit 132 determines that the access point 2A is an access point that is restricted by communication based on the communication amount, and the access point 2B is an access point that is restricted by communication based on the communication amount, The connection of point 2A may be maintained.

  In addition, when the access point 2A is an access point that is not subject to communication restriction based on the communication amount, the selection unit 132 determines whether the access point 2B is an access point that is subject to communication restriction based on the communication amount. Regardless, the connection of the access point 2A may be maintained.

[Select access point based on connection time]
Further, the selection unit 132 refers to the connection history, and selects the access point 2 to be connected based on the connection time with the access point 2 corresponding to the wireless communication network in which communication restriction is performed based on the connection time within a predetermined period. You may choose.

  Specifically, when the detection unit 131 newly detects the access point 2B while being connected to the access point 2A, the selection unit 132 confirms the network type corresponding to the access point 2A, thereby It is determined whether the access point is subject to communication restrictions based on the connection time in time.

  When the selection unit 132 determines that the access point 2A is an access point to which communication is restricted based on the connection time, the total connection time included in the communication history information of the access point 2A stored in the storage unit 12 is: It is determined whether or not the second threshold is exceeded. Here, the second threshold is a value (for example, 80 hours) determined based on a communication restriction reference value (for example, 100 hours). When the selection unit 132 determines that the total connection time corresponding to the access point 2A exceeds the second threshold, the selection unit 132 selects the access point 2B as the access point 2 to be connected. By doing in this way, the portable terminal 1 can change the connection destination so that the connection time of communication via the wireless communication network does not exceed the time required for communication restriction.

[Select access point based on connection time since connection]
Moreover, the selection part 132 may select the access point 2 to connect with reference to a connection history based on the continuous connection time with the access point 2 which the portable terminal 1 connected in the past. Here, the access point 2 connected in the past is the access point 2 connected within a predetermined time (for example, within 30 minutes).

  Specifically, when the detection unit 131 newly detects the access point 2A and the access point 2B, the selection unit 132 refers to the continuous connection time included in the connection history information corresponding to the access point 2 connected within a predetermined time. Then, it is determined whether or not the continuous connection time is smaller than a third threshold (for example, 5 minutes). Here, when there are a plurality of access points 2 connected within a predetermined time, the selection unit 132 determines whether or not all the continuous connection times corresponding to the respective access points 2 are smaller than the third threshold value. Determine.

  Here, when the continuous connection time is smaller than the third threshold value, there is a high possibility that the mobile terminal 1 is moving. For this reason, when the selection unit 132 determines that the continuous connection time is smaller than the third threshold, the access point 2 corresponding to the network type indicating the wireless communication network having a wide communication range from the plurality of detected access points 2. Is selected as the access point 2 to be connected. For example, when the selection unit 132 determines that the continuous connection time is smaller than the third threshold, the selection unit 132 selects the access point 2 corresponding to the WiMAX line or the mobile phone line. By doing in this way, when the communication status is unstable due to movement, the mobile terminal 1 can perform stable communication by setting the access point 2 corresponding to the wireless communication network having a wide communication range as the connection destination. It can be carried out.

The connection unit 133 establishes communication connection with the access point 2 selected by the selection unit 132. Specifically, the connection unit 133 disconnects the communication connection with the access point 2A when the selection unit 132 selects the access point 2B as the access point 2 to be connected in a state in which the connection unit 133 is connected to the access point 2A. At the same time, communication connection is made to the access point 2B. When the network type of the access point 2 connected for communication indicates a cellular phone line, the connection unit 133 connects to the access point 2B while maintaining the communication connection with the access point 2. Also good.
In addition, when connecting to the access point 2B, the connection unit 133 causes the storage unit 12 to store connection history information indicating a connection history with the access point 2B.

[Processing flow in portable terminal 1]
Next, a process flow when the mobile terminal 1 connects to the access point 2 will be described. FIG. 5 is a flowchart showing a flow of processing when the mobile terminal 1 according to the first embodiment connects to the access point 2.

  First, the selection unit 132 determines whether or not the detection unit 131 has detected the access point 2 (S10). If the selection unit 132 determines that the access point 2 has been detected, the selection unit 132 shifts the process to S20. If the selection unit 132 determines that the access point 2 has not been detected, the selection unit 132 re-executes S10.

  Subsequently, when the detection unit 131 newly detects the access point 2, the selection unit 132 receives the data reception amount, the total connection time, and the continuous connection included in the connection history corresponding to the access point 2 to which the mobile terminal 1 has connected in the past. Based on at least one of the times, it is determined whether or not to connect to the newly detected access point 2 (S20). If the selection unit 132 determines to connect to the newly detected access point 2, the process proceeds to S30. If the selection unit 132 determines not to connect to the newly detected access point 2, the process proceeds to S10.

Subsequently, the connection unit 133 performs connection processing for communication connection to the access point 2 determined to be connected by the selection unit 132 (S30).
Subsequently, the connection unit 133 causes the storage unit 12 to store connection history information indicating a connection history with the newly connected access point 2 (S40). If connection history information corresponding to the access point 2 is already stored in the storage unit 12, the connection unit 133 updates the connection history information.

[Effect in the first embodiment]
As described above, the mobile terminal 1 selects and selects the access point 2 to be connected from the plurality of access points 2 detected by the detection unit 131 based on the connection history corresponding to the access point 2 to which the mobile terminal 1 has connected in the past. The access point 2 is connected to the communication. By doing in this way, even if it is a case where the new access point 2 is detected, the portable terminal 1 connects to the said new access point based on the connection log | history corresponding to the access point 2 connected in the past. It is possible to appropriately determine whether or not.

<Second Embodiment>

Here, each of the portable terminal 1A and the portable terminal 1B transmits connection history information to the access point 2C. The access point 2C is an access point 2 related to the access point 2A. Based on the received connection history information, the access point 2C provides the mobile terminal 1 that has transmitted the connection history on the condition that the access point 2 corresponding to the connection history information is the access point 2 associated with itself. The distribution information is distributed.

  In FIG. 6B, since the mobile terminal 1A transmits a connection history with the access point 2A of the sightseeing bus 4 associated with the access point 2C, the access point 2C transmits the tourist information etc. to the mobile terminal 1A. Distribute distribution information. In addition, since the mobile terminal 1B transmits a connection history with the access point 2B not related to the access point 2C, the access point 2C does not distribute distribution information such as tourist information to the mobile terminal 1B.
