  The present invention relates to a portable electronic device having a plurality of communication processing units, a control method for controlling the device, and a control program for controlling the device.

  Recent portable electronic devices have a function capable of supporting a plurality of radio bearers. For example, according to Patent Document 1, when establishing a network using any one of a plurality of radio bearers, there is a technique for selecting an optimum radio bearer in consideration of application characteristics for each application. It is disclosed.

International Publication No. 2007/099700

  By the way, in general, portable electronic devices define priority rules regarding which radio bearer is preferentially used in a state where a plurality of radio bearers can be used.

  Here, when data communication is performed using an upper radio bearer, an authentication error occurs due to a password change or the like, and a lost state (that is, an AP (access point) can be confirmed from the upper radio bearer) ).

  The portable electronic device switches from the upper radio bearer in the lost state to the middle radio bearer and continues data communication. After that, when the middle radio bearer is lost, the portable electronic device tries to establish a network with the higher radio bearer according to the priority rule. Since the portable electronic device is in a state where the AP corresponding to the upper radio bearer can be confirmed, it makes a network connection request to this AP. In this case, since the AP causes an authentication error, the portable electronic device performs data communication using the lower bearer when the AP corresponding to another upper radio bearer cannot be confirmed.

  In this way, in the portable electronic device, when the upper radio bearer is lost due to an authentication error and then the middle radio bearer is lost, the processing by the upper radio bearer that causes an authentication error according to the priority rule. As a result, time and processing are wasted.

And a control unit that controls each processing unit as the third communication processing unit, and the control unit performs data communication after establishing a connection with the network by the second communication processing unit, and performs the second communication. When the data communication is performed by the processing unit and the connection with the network is disconnected, the signal is intermittently received before the connection with the network is disconnected regardless of the order. The third communication processing unit in the state Ri is configured to control so as to continue the data communication.

  In order to solve the above-described problem, the electronic device according to the present invention determines the order in which the electronic device is preferentially used when performing data communication as the first communication processing unit, the second communication processing unit, and the third communication processing A control unit that controls each processing unit as a unit, wherein the first communication processing unit performs communication by a first communication method, and the second communication processing unit performs communication by a second communication method.

The operation performed by the smartphone 1 according to the determined gesture differs depending on the screen displayed on the touch screen display 2.

  An example of a screen displayed on the display 2A will be described with reference to FIG. FIG. 4 shows an example of the home screen. The home screen may be called a desktop or a standby screen. The home screen is displayed on the display 2A. The home screen is a screen that allows the user to select which application to execute from among the applications installed in the smartphone 1. The smartphone 1 executes the application selected on the home screen in the foreground. The screen of the application executed in the foreground is displayed on the display 2A.

  The smartphone 1 can place an icon on the home screen. A plurality of icons 50 are arranged on the home screen 40 shown in FIG. Each icon 50 is associated with an application installed in the smartphone 1 in advance. When the smartphone 1 detects a gesture for the icon 50, the smartphone 1 executes an application associated with the icon 50. For example, when the smartphone 1 detects a tap on the icon 50 associated with the mail application, the smartphone 1 executes the mail application. Here, for example, the smartphone 1 interprets a gesture to a position (area) corresponding to the display position (area) of the icon 50 on the touch screen display 2 as an execution instruction of an application associated with the icon 50. .

  Note that the home screen 40 shown in FIG. 4 is an example, and the form of various elements, the arrangement of various elements, the number of home screens 40, the manner of various operations on the home screen 40, and the like are described above. It does not have to be street.

FIG. 5 is a block diagram illustrating the configuration of the smartphone 1.
The smartphone 1 includes a control unit 30, a first communication processing unit 31, a first antenna unit 32, a second communication processing unit 33, a second antenna unit 34, and a third communication processing unit 35. And a third antenna unit 36. The smartphone 1 includes other components such as a microphone in addition to the components described above.

  The first communication processing unit 31 conforms to the first communication method. The second communication processing unit 33 conforms to the second communication method. The third communication processing unit 35 conforms to the third communication method. In the following, since the communication by the first communication processing unit 31 is set higher in priority than the communication by the second communication processing unit 33 and the third communication processing unit 35, it is also referred to as upper bearer communication. . The second communication processing unit 33 is also called middle bearer communication because the priority is set higher than the communication by the third communication processing unit 35. The communication by the third communication processing unit 35 is also referred to as lower bearer communication.

  The control unit 30 controls each processing unit as the first communication processing unit 31, the second communication processing unit 33, and the third communication processing unit 35 in the order of preferential use when performing data communication. . That is, when all of the first communication processing unit 31, the second communication processing unit 33, and the third communication processing unit 35 are available, the control unit 30 preferentially uses the first communication processing unit 31. Data communication is performed using. Further, when data communication by the first communication processing unit 31 is not possible, the control unit 30 preferentially performs data communication by the second communication processing unit 33.

  In addition, when data communication is performed by the second communication processing unit 33, the control unit 30 uses the third communication processing unit 35 when an authentication error occurs due to a password change or the like and the network is disconnected. Then, control is performed to continue the data communication.

  Here, when data communication is performed by the second communication processing unit 33, if the network is disconnected, data communication is performed using the first communication processing unit 31 according to the order of priority use. Then, it is considered that there are many cases where the first communication processing unit 31 cannot be used. This is because data communication by the second communication processing unit 33 means that data communication by the first communication processing unit 31 cannot be performed.

  The third communication processing unit 35 always performs intermittent reception under a predetermined condition, and can be in an active state (a state where data communication can be performed) at any time. The predetermined condition means that the radio wave intensity is sufficient for data communication.

  In this way, the smartphone 1 can select a communication processing unit that can be efficiently connected while suppressing waste of time and processing.

  Moreover, although the structure and operation | movement of the smart phone 1 were demonstrated above, it is not restricted to this, The control method for selecting a communication processing part efficiently provided with each component, suppressing the waste of time and a process, and It may be configured as a control program.

  In addition, when the smartphone 1 is already connected by the first communication processing unit 31, it is not necessary to connect to the third communication processing unit 35 based on the priority order, and thus the first communication processing unit 31. It may be configured to check whether is connected.

  In addition, when the third communication processing unit 35 is invalid or out of service area, the smartphone 1 is useless even if a connection request is issued by the third communication processing unit 35. Therefore, the setting of the third communication processing unit 35 is not necessary. When data communication is performed by the second communication processing unit 33 on the condition that it is valid and within range, an authentication error occurs due to a password change or the like, and the network is disconnected. The configuration may be such that the communication processing unit 35 is used to control the data communication to be continued.

  The first communication method is, for example, a communication standard (wireless LAN) compliant with IEEE 802.11. The second communication method is, for example, a communication standard that conforms to IEEE 802.16. The third communication method is, for example, a communication method (for example, CDMA2000 1xEV-DO Rev. A) that conforms to the IMT-2000 standard.

  FIG. 6 shows the frequency used in each communication standard, the maximum transfer rate, and the maximum communication distance. Therefore, when the first communication processing unit 31 (for example, IEEE802.11n) is used, the transfer speed is the fastest, so that high-speed data communication can be realized.

  Further, when the second communication processing unit 33 is used, the communication distance is longer than when the first communication processing unit 31 is used, and the transfer speed is higher than when the third communication processing unit 35 is used. Since it is fast, high-speed data communication can be realized in a wide area.

  Further, when the third communication processing unit 35 is used, since the communication distance is the longest, data communication can be realized in a wide area.

  In addition, when the data communication is performed by the first communication processing unit 31 and the network is disconnected, the control unit 30 can use the second communication processing unit 33 to continue the data communication. Judging. If the control unit 30 determines that the data communication can be continued, the control unit 30 uses the second communication processing unit 33 to continue the data communication and whether the first communication processing unit 31 can perform the data communication. Judgment is made at a predetermined cycle.

  In addition, when the control unit 30 determines that data communication is possible by the first communication processing unit 31 in a state where data communication is continued using the second communication processing unit 33, The data communication by the second communication processing unit 33 is terminated, and the first communication processing unit 31 performs control so as to continue the data communication.

  Specifically, as shown in FIG. 7, when the network is disconnected (t <b> 1 in FIG. 7) when the data communication is performed by the first communication processing unit 31, the control unit 30 performs the second The communication processing unit 33 performs a process for establishing a network (hereinafter referred to as a connection request process), and determines whether data communication is possible. The connection request process refers to a series of processes for searching for a nearby base station and performing an authentication process with the discovered base station so that actual data communication can be performed.

When the data communication by the second communication processing unit 33 is possible as a result of the connection request process, the control unit 30 performs the data communication by the second communication processing unit 33.
The control unit 30 performs connection request processing by the first communication processing unit 31 at a predetermined cycle. The predetermined cycle is, for example, timings indicated by t2 and t3 in FIG.

  Further, when data communication is performed by the second communication processing unit 33, the control unit 30 performs data communication by the third communication processing unit 35 when the network is disconnected (t4 in FIG. 7). Note that the third communication processing unit 35 always performs intermittent reception under predetermined conditions, and can be in an active state (a state where data communication can be performed) at any time.

  In addition, the control unit 30 performs connection request processing by the second communication processing unit 33 at a predetermined cycle. The predetermined cycle is, for example, a timing indicated by t5 in FIG.

  Note that the control unit 30 performs connection request processing, and performs control to switch to data communication by the first communication processing unit 31 when data communication by the first communication processing unit 31 is possible. The control unit 30 performs connection request processing, and data communication by the first communication processing unit 31 is not possible. However, when data communication by the second communication processing unit 33 is possible, the second communication is performed. Control to switch to data communication by the processing unit 33 is performed.

  Here, conventionally, when data communication is performed by the second communication processing unit 33, when the network is disconnected (t4 in FIG. 7), the first communication processing unit at the disconnection timing. The connection request processing by 31 was performed. In this case, it is considered that there are many cases where the first communication processing unit 31 cannot be used.

  In this way, the smartphone 1 can select a communication processing unit that can be efficiently connected while suppressing waste of time and processing.

  Next, when data communication is performed by the smartphone 1, an operation of switching each communication processing unit according to a situation will be described with reference to a flowchart illustrated in FIG. In the following embodiments, description will be made assuming that data communication is performed by the second communication processing unit 33. In addition, it is assumed that the control unit 30 performs connection request processing by the first communication processing unit 31 at a predetermined cycle.

  In step ST1, the control unit 30 determines whether or not the network has been disconnected (lost) due to an authentication error due to a password change or the like when data communication is performed by the second communication processing unit 33. If lost (Yes), the process proceeds to step ST2, and if not lost (No), the process proceeds to step ST6.

  In step ST <b> 2, the control unit 30 performs connection request processing by the third communication processing unit 35.

  In step ST3, the control unit 30 determines whether or not the connection request process in the process of step ST2 has succeeded. If the connection request process is successful (Yes), the process proceeds to step ST4. If the connection request process is not successful (No), the process proceeds to step ST5.

  In step ST4, the control unit 30 continues the data communication using the third communication processing unit 35. The control unit 30 performs connection request processing by the first communication processing unit 31 at a predetermined cycle.

  In step ST5, the control unit 30 performs connection request processing by the first communication processing unit 31, the second communication processing unit 33, and the third communication processing unit 35 at a predetermined cycle.

  In step ST6, the control unit 30 determines whether or not the connection request processing by the first communication processing unit 31 performed at a predetermined cycle has succeeded. If the connection request process is successful (Yes), the process proceeds to step ST7. If the connection request process is not successful (No), the process returns to step ST1.

  In step ST <b> 7, the control unit 30 performs control to switch from data communication by the second communication processing unit 33 to data communication by the first communication processing unit 31.

  In this way, the smartphone 1 can select a communication processing unit that can be efficiently connected while suppressing waste of time and processing.
