Description

  The present invention relates to a wireless communication apparatus having a wired communication unit capable of wired communication and a wireless communication unit capable of wireless communication.

  The communication timeout time when the network connection device connects to the application is common to wired / wireless.

  However, in the case of wireless communication, radio frequency interference from external devices, especially the frequency used in a microwave oven, etc., is close to the frequency used in wireless communication, and the communication speed is slower than wired communication. Therefore, if a problem occurs in the communication quality during that time, the communication time becomes long as a result, the time-out occurs and the communication ends in the middle, and it is necessary to manually reconnect each time.

  On the other hand, for example, Patent Document 1 proposes a point corresponding to these problems by changing parameters used for communication in a wired section and a wireless section.

Further, the information processing apparatus 10 is connected to the mobile terminal 30 via wireless.

  Here, the wired network may be a LAN such as Ethernet (registered trademark), or may be a WAN such as an optical line. The wireless network is configured by a wireless LAN such as WiFi such as IEEE802.11a / b / g.

[2. Functional configuration]
Subsequently, FIG. 2 is a block diagram for explaining a functional configuration of the information processing apparatus 10. The information processing apparatus 10 includes a control unit 100, a wireless communication unit 200, a wired communication unit 300, a timeout time calculation unit 400, a communication method detection unit 500, and a storage unit 600.

  The control unit 100 is a functional unit for controlling the entire information processing apparatus 10. The control unit 100 realizes various functions by reading and executing various programs stored in the storage unit, and is configured by, for example, a CPU (Central Process Unit).

  The wireless communication unit 200 is an interface unit for performing data transmission / reception with another portable terminal via the antenna 250. For example, a network interface card (NIC) corresponding to IEEE 802.11a is included.

  In addition, the wireless communication unit 200 includes a Ping acquisition unit 210, a timer unit 220, and a storage unit 230. The Ping unit 220 is a functional unit that acquires Ping data (for example, reaction time when a Ping signal is transmitted to another device) via the wireless LAN.

  The timer unit 220 is a time measuring unit that measures the time until timeout. The time until timeout is stored as timeout information 232 in the storage unit 230.

  The timeout time calculation unit 400 is a functional unit for calculating a time until timeout, which will be described later. In addition, the communication method detection unit 500 determines whether the current communication is a wired LAN (communication is performed via the wired communication unit 300) or a wireless LAN (whether communication is performed via the wireless communication unit 200). It is a functional part for detecting.

  The storage unit 500 is a functional unit that stores various programs and various data necessary for the operation of the information processing apparatus 10. The storage unit 500 is configured by, for example, a semiconductor memory, an HDD (Hard Disk Drive), or the like.

  Hereinafter, with respect to the wireless communication apparatus in the information processing apparatus 10, a method for determining the time until the wireless timeout will be described using the following embodiments.

[3. Example]
[3.1 First Example]
The first embodiment will be described. FIG. 3 shows a method for determining the timeout time at the time of wireless connection by comparing the communication speed with the data at the time of wireless connection based on the Ping data at the time of wired connection.

  First, it is determined whether or not a record of acquiring the communication speed (Ping) in the past via the wired LAN is stored (step S102). If the record is not stored (step S102; No), the wired LAN is used to connect to an external device (step S104), and the communication speed Ta by the wired LAN is measured (step S106). Then, the measured communication speed Ta is stored (step S108).

  On the other hand, when the communication speed has been acquired via the wired LAN in the past (step S102; Yes), the stored communication speed Ta is read (step S110).

  Next, the wireless LAN is used to connect to an external device (step S112), and the wireless LAN communication speed Tb is measured (step S114).

  Here, the connection by wireless LAN, unlike the connection by wired LAN, may be affected by external influences and the communication speed Tb may change greatly. Therefore, every connection, every predetermined time, every predetermined number of connections. It is better to measure. In this embodiment, the measurement is performed every time the connection is made.

  Next, the timeout time at the time of wired LAN connection is read (step S116). Thus, the wireless timeout time is calculated using the communication speed Ta measured using the wired LAN, the communication speed Tb measured using the wireless LAN, and the timeout time TM when connecting to the wired LAN (step S118). . Specifically, the wireless LAN timeout time is calculated by Tm × Ta / Tb.

  Then, the calculated wireless timeout time is set (step S120). When the wireless LAN is connected, the set value is used by the timer unit 220.

[3.2 Second Embodiment]
Next, a method of determining a timeout time during wireless connection based on a wired LAN connection method will be described with reference to FIG.

  First, a wired LAN connection method is acquired in the past by Auto Negotiation, and it is determined whether it is stored (step S202). If the connection method is not stored here (step S202; No), it is connected to an external device using a wired LAN (step S204), and the connection method is acquired by auto negotiation using a wired LAN connection (step S206). Then, the acquired wired LAN connection method is stored (step S208).

  On the other hand, if the connection method of the wired LAN is acquired in the past by Auto Negotiation and stored (step S202; Yes), the stored wired LAN connection method is read (step S210).

  Subsequently, the wired LAN connection method is determined (step S212). Thereby, a correction value is determined. Specifically, when the wired LAN connection method is 10BASE, the correction value T1 is (step S214), when the wired LAN connection method is 100BASE, the correction value T2 is (step S216), and the wired LAN connection method is 1000BASE. In this case, the correction value T3 is read from the storage unit (step S218) and determined.

  Then, the wireless LAN timeout time is calculated by applying a correction value called from the storage unit to the preset wired LAN timeout time Tm (step S220), and the wireless LAN timeout time is set. (Step S222). As a result, the set value is used by the timer unit 220 when the wireless LAN is connected.

  That is, as shown in FIG. 5, for example, when the connection method after Auto Negotiation of the wired LAN is “100BASE”, T2 is read as the correction value T corresponding to the connection method. Then, the timeout time in the wireless LAN is calculated as Tm × T2.

[3.3 Third Example]
Next, a method for measuring the communication speed of the wireless LAN and determining the timeout time during wireless connection will be described with reference to FIG.

  First, it connects with other apparatuses (for example, portable terminal 30) using wireless LAN (Step S302), and acquires a communication speed in this case (Step S304).

  Next, for the acquired communication speed of the wireless LAN (step S306), the corresponding correction value is called from the storage unit based on the communication speed from the correction value stored in advance for each communication speed range.

  Specifically, for example, if the wireless LAN communication speed is less than 500 kbps, the correction value is 10 (step S308), and if it is 500 kbps or more and less than 10 Mbps, the correction value is 5 (step S310), 10 Mbps or more and less than 20 Mbps. If so, the correction value is set to 2 (step S312), and if it is 20 Mbps or more, the correction value is set to 1 (step S314).

  Subsequently, the preset wired LAN timeout time Tm is read (step S316), and the wireless LAN timeout time is calculated by applying the correction value read from the storage unit (step S318). The calculated time-out time in the wireless LAN is set (step S320), and the set value is used by the timer unit 220 when the wireless LAN is connected.

  That is, as illustrated in FIG. 7, for example, when the wireless communication speed is “5 Mbps”, the correction value is read as “5”. Then, the timeout time in the wireless LAN is calculated as Tm × 5.

[4. Modified example]
The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the design and the like within the scope of the present invention are also within the scope of the claims. include.

  The wireless communication apparatus (wireless communication method) of the present invention has been described by taking a computer incorporating the wireless communication apparatus as an example, but any apparatus having a wireless communication function may be used. For example, it may be a communication device such as a wireless router, a mobile phone, a mobile router, a smartphone, or a communication device such as a wireless base station. Further, a device having a communication function, for example, an image forming device, a game machine, a video display device, or the like may be used.

  In the above-described embodiment, the correction value when calculating the timeout time in the wireless LAN has been described using a flow for convenience of description. However, since the value is read from the table, the correction value calculation process ( For example, in the case of the third embodiment, it is needless to say that the processing may be performed as step S330) of FIG.
