  Communication devices equipped with touch screen displays, such as smartphones or tablet terminals, tend to require a lot of power for application execution, display, communication, etc., with higher functionality, especially in portable communication devices, There is a need to reduce power consumption without reducing user convenience.

  As an example for reducing power consumption, when the communication is disconnected in a communication system with a higher priority among a plurality of communication systems when the display is turned off, the control unit immediately establishes communication connection to the communication system. The communication connection trial is started when the display is displayed without starting the trial.

  As a result, when there is a high possibility that the user is not operating such as when the display is turned off, it is possible to reduce wasteful power consumption by reducing wasteful communication connection attempts.

  However, due to the reception of messages transmitted simultaneously to a plurality of terminals such as earthquake early warnings, the display of a plurality of portable wireless devices may be displayed all at once. In such a case, a plurality of terminals start communication connection trials to the communication system all at once due to display on the display. Then, the authentication process for the authentication server in the network that occurs in the process of communication connection is concentrated, and the load on the network increases, such as the authentication server being down.

  Therefore, an object of the present invention is to reduce the load on the network.

  The portable wireless device of the present invention includes a display unit, a communication unit capable of transmitting and receiving data by at least one of a plurality of communication systems, and display by the display unit due to occurrence of a predetermined event. If performed, the communication by each of the plurality of communication systems according to the connection state of the communication by the plurality of communication systems and the communication history so far by the plurality of communication systems when the display by the display unit is performed And a control unit that determines whether or not to start a connection attempt.

  Preferably, the communication history is a total amount of data transmitted / received so far or a communication time by communication executed so far.

  Preferably, the occurrence of the predetermined event is reception of an earthquake early warning.

  Preferably, the total capacity of the data is a total capacity of data transmitted and received between the occurrence of the predetermined event and a predetermined time.

  Preferably, the plurality of communication systems include a first communication system and a second communication system having a higher priority than the first communication system, and the control unit is displayed by the display unit. At the time, when the communication connection is established by the first communication system, the total amount of data transmitted / received by the second communication system that is not currently connected by the communication is determined so far by the first communication system. If it is smaller than the total amount of data transmitted and received, the communication connection trial in the second communication system is started.

  Preferably, the plurality of communication systems further includes a third communication system having a higher priority than the first communication system and a lower priority than the second communication system, and the control unit includes the display When the display by the first communication system is performed and the communication connection is performed by the first communication system and the communication connection by the second communication system is not attempted, the third communication system that is not currently connected by communication is used. If the total capacity of data transmitted / received so far is smaller than the total capacity of data transmitted / received so far by the first communication system, communication connection trial in the third communication system is started.

FIG. 4 is a sequence diagram showing a part of the details in the sequence diagram of FIG.

  FIG. 1 is a block diagram showing functions of a cellular phone 1 according to an embodiment of a portable radio apparatus of the present invention.

  The mobile phone 1 includes a control unit 10, a communication unit 20, a storage unit 30, a display unit 40, an operation unit 50, and a voice control unit 60.

  The control unit 10 controls the entire mobile phone 1, and performs predetermined control on each unit such as the communication unit 20 and the display unit 40, for example. The control unit 10 receives various inputs from the operation unit 50 or the communication unit 20 and executes various processes. And the control part 10 controls the memory | storage part 30 in the case of a process execution, reads various programs and data, and writes data. Details thereof will be described later.

  The communication unit 20 communicates with an external device (such as a base station configuring a network in each communication system) using a predetermined use frequency band (for example, a 2 GHz band or an 800 MHz band). Then, the communication unit 20 demodulates the signal received from the antenna, supplies the processed signal to the control unit 10, modulates the signal supplied from the control unit 10, and transmits the signal from the antenna to the external device. To do.

  Here, in the present embodiment, the communication unit 20 is a communication system used for W-CDMA, CDMA20001x (hereinafter, 1x) or GSM, which is a communication system used for both voice communication and data communication, and data communication. It supports certain CDMA20001xEV-DO (hereinafter EVDO) or WiMAX, LTE (Long Term Evolution) which is a communication system mainly used for high-speed data communication, and wireless LAN, and can be communicated by any communication system. . A wireless LAN refers to a communication system compliant with, for example, IEEE 802.11. Hereinafter, W-CDMA, 1x, and EVDO are collectively referred to as 3G.

  In the present embodiment, the communication unit 20 performs communication mainly by wireless LAN, WiMAX, 3G, but usable ones are not limited to these three types of communication systems.

  The communication unit 20 communicates with an external device through any one communication system or any one of a plurality of communication systems based on a command from the control unit 10. The communication unit 20 tries communication connection when starting communication. For example, WiMAX is an example of a communication connection attempt. First, a search for a neighboring base station is performed, and if there is a neighboring base station, the base station to which it is connected is identified. After establishment of radio with a station, it means that authentication by an authentication server and IP address acquisition by a DHCP server are performed. The communication unit 20 establishes a communication connection with the network through such a communication connection attempt, and performs communication with the server and other mobile phones via the network.

  The communication unit 20 communicates in the order of wireless LAN, WiMAX, 3G based on a predetermined priority order based on a command from the control unit 10 in a state where communication connection is not established by any communication system. Attempt to connect. Here, the priority of communication connection trials is determined in the order of wireless LAN, WiMAX, and 3G. The communication unit 20 first tries communication connection by wireless LAN, and when communication connection by wireless LAN fails, tries communication connection by WiMAX, and when communication connection by WiMAX fails, communication connection by 3G If the 3G communication connection fails, it is out of service area.

  The storage unit 30 includes, for example, a working memory and is used for arithmetic processing by the control unit 10. In addition, various programs according to the present embodiment are stored. In addition, the storage unit 30 cumulatively stores the capacity of data (including call voice data) transmitted and received by each communication system (wireless LAN, WiMAX, 3G). In addition, the storage unit 30 cumulatively stores the communication time and the number of communication disconnections by each communication system.

  The display unit 40 is, for example, a liquid crystal display, an organic EL (Electro Luminescence) display, or the like. The display unit 40 displays a screen in response to an instruction from the control unit 10. Here, the display of the screen by the display unit 40 includes lighting of the display unit 40 by activation of the backlight of the display unit 40.

  The operation unit 50 includes, for example, a button, a keyboard, a touch sensor, and the like. When operated by the operation unit 50, the result of the operation is input to the control unit 10. Upon receiving the input, the control unit 10 executes control according to the input.

  The voice control unit 60 performs predetermined voice processing on the signal supplied from the communication unit 20 under the control of the control unit 10 and outputs the processed signal to a receiver (not shown). The receiver outputs the signal supplied from the audio control unit 60 to the outside. Note that this signal may be output from a speaker (not shown) instead of or together with the receiver.

  In addition, the voice control unit 60 processes a signal input from a microphone (not shown) under the control of the control unit 10 and outputs the processed signal to the communication unit 20. The communication unit 20 performs predetermined processing on the signal supplied from the audio control unit 60 and outputs the processed signal from the antenna.

  A detailed configuration of the control unit 10 will be described below.

  The control unit 10 instructs the display unit 40 to display a screen on the display unit 40 due to occurrence of a predetermined event. The predetermined event here refers to, for example, reception of a message broadcasted simultaneously from a base station to unspecified users in an emergency such as an earthquake early warning. When a predetermined event occurs, the control unit 10 instructs the display unit 40 to display a screen on the display unit 40. As a result, the display unit 40 displays a screen.

  Next, the control unit 10 performs communication by each of the plurality of communication systems according to the connection state of the communication by the plurality of communication systems and the communication history by the plurality of communication systems at the time when the display by the display unit 40 is performed. Determine whether to initiate a connection attempt. The connection state of communication by a plurality of communication systems here refers specifically to either the state of communication connection by each communication system or the state of being disconnected. In addition, the communication history so far by a plurality of communication systems is the sum of the capacities of data (including call voice data) transmitted / received up to the time point when the display is performed on the display unit 40 or executed so far It is a communication time by communication. The communication time here refers to, for example, a call time or a time taken for packet transmission / reception by data communication. In addition, the total amount of data here refers to the total amount of data transmitted and received between the occurrence of a predetermined event and a predetermined time, and the predetermined time is, for example, 24 hours.

  When it is determined that the communication connection attempt is started, the control unit 10 starts the communication connection attempt. If the control unit 10 determines that the communication connection attempt is not started, the control unit 10 does not start the communication connection attempt and performs communication using the communication system that has already established the communication connection.

  FIG. 2 is a sequence diagram showing processing of the first exemplary embodiment of the present invention.

  3 and 4 are sequence diagrams showing details of a part of the sequence diagram of FIG.

  The control unit 10 monitors whether display by the display unit 40 is executed due to occurrence of a predetermined event in a so-called non-display state (step S1) where nothing is displayed by the display unit 40. (Step S2). If the predetermined event has not yet occurred (NO in step S2), the control unit 10 continuously monitors whether display by the display unit 40 resulting from the occurrence of the predetermined event has been executed. Further, the control unit 10 instructs the display unit 40 to display the screen due to the occurrence of an event other than the predetermined event (operation by the user, etc.), and the display unit 40 displays the screen. In the case of communication, the communication unit 20 tries communication connection by wireless LAN and WiMAX as usual.

  Further, the control unit 10 instructs the display unit 40 to display a screen due to the occurrence of a predetermined event, and when the display unit 40 displays the screen (YES in step S2), It is determined whether or not a connection is established via a wireless LAN (step S3). If it determines with the control part 10 being connected by wireless LAN (step S3 YES), it will not try the communication connection by another communication system. Note that “being connected” here refers to a state in which, for example, after authentication with the base station is established, authentication of the authentication server is completed and the connection is not disconnected.

  If the control unit 10 determines that the wireless LAN is not connected (step S3 NO), the control unit 10 determines whether the connection is established using WiMAX (step S4). If it determines with the control part 10 being connected by WiMAX (step S4 YES), it will determine whether the communication amount by WiMAX is larger than the communication amount by wireless LAN (step S11). Here, the communication amount indicates the total capacity of data (which may include call voice data) transmitted and received by wireless LAN or WiMAX communication so far. The total capacity is expressed in units of bytes or bits, for example.

  If the control unit 10 determines that the communication amount by WiMAX is larger than the communication amount by the wireless LAN (YES in step S11), the control unit 10 tries communication connection by the wireless LAN (step S12). On the other hand, when it determines with the communication amount by WiMAX being below the communication amount by wireless LAN (step S11 NO), the control part 10 does not try the communication connection by wireless LAN.

  Next, when it determines with the control part 10 not being connected by WiMAX (step S4 NO), it determines whether it is connecting by 3G (step S5). If it determines with the control part 10 being connected by 3G (step S5 YES), it will determine whether the communication amount by 3G is larger than the communication amount by wireless LAN (step S21). When it is determined that the communication amount by 3G is larger than the communication amount by the wireless LAN (step S21 YES), the control unit 10 tries communication connection by the wireless LAN (step S22).

  Further, the control unit 10 determines whether the communication amount by the 3G is less than or equal to the communication amount by the wireless LAN before the communication connection is attempted by the wireless LAN in step S22, during or after the trial, or when the communication amount by the 3G is equal to or less than the communication amount by the wireless LAN (step S21 NO). It is determined whether or not the communication amount is larger than the communication amount by WiMAX (step S23). Therefore, when the control unit 10 determines that the communication amount by 3G is larger than the communication amount by WiMAX (step S23 YES), the control unit 10 tries communication connection by WiMAX (step S24). On the other hand, when the control unit 10 determines that the communication amount by 3G is equal to or less than the communication amount by WiMAX (NO in step S23), the control unit 10 does not attempt communication connection by WiMAX.

  If it is determined that the connection is not being established by 3G (NO in step S5), the control unit 10 tries communication connection by wireless LAN and communication connection by WiMAX (step S6). Here, the control unit 10 may try communication connection only with either the wireless LAN or WiMAX.

  According to the embodiment of the present invention, a plurality of mobile phones are simultaneously displayed on the display unit, and are started all at once by imposing a certain condition on trying to establish a communication connection by wireless LAN and WiMAX. It is possible to reduce the load on the authentication server or the like in the wireless LAN and WiMAX networks. In addition, if a certain condition is satisfied, a communication connection attempt to a communication system having a higher priority than the currently connected communication system can be started. Therefore, communication by a communication system desired by the user is performed as much as possible. It is possible to obtain necessary information quickly in an emergency.

  Further, in the above embodiment, when the communication amount by the currently connected communication system is larger than the communication amount by the other communication system by comparing the communication amount by the currently connected communication system with the communication amount by the other communication system. Is to start a communication connection attempt by another communication system, but is not limited to this. For example, the accumulated time of communication by the currently connected communication system and the accumulated time of communication by another communication system are calculated. In contrast, if the accumulated time of communication by the currently connected communication system is larger than the accumulated time of communication by another communication system, a communication connection attempt by another communication system may be started.

  Also, comparing the number of times of communication disconnection by the currently connected communication system and the number of times of communication disconnection by another communication system, the number of times of communication disconnection by the currently connected communication system is greater than the number of communication disconnections by the other communication system. If the number is larger than the number of times, a communication connection attempt by another communication system may be started. Further, the cutting frequency may be used instead of the cutting frequency.

  In addition, the number of communication connections by the currently connected communication system is compared with the number of communication connections by the other communication system by comparing the number of communication connections by the currently connected communication system with the number of communication connections by other communication systems. If the number is larger than the number of times, a communication connection attempt by another communication system may be started. Further, the connection frequency may be used instead of the connection count.

  In the above-described embodiment, the three types of communication systems of wireless LAN, WiMAX, and 3G have been described as examples. However, the present invention is not limited thereto, and for example, WiMAX in this embodiment is replaced with LTE and 3G is excluded. Two types of communication systems may be used: wireless LAN and LTE. In addition, the combination of the three types of communication systems may be any combination, and the types of communication systems are not limited to three types, and may be two types or four types, for example.

  Also, in the present embodiment, the case of not trying to establish a wireless LAN communication connection means that communication connection is not attempted to a specific SSID access point, and communication connection is attempted to another SSID access point. It is good as well. The specific SSID here is, for example, the SSID of the access point corresponding to the public wireless LAN.

  As mentioned above, although embodiment of this invention was described, this invention is not restricted to embodiment mentioned above. Further, the effects described in the embodiments of the present invention only list the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the above-described embodiments. Absent.
