JP4507783B2 - E-mail automatic receiving method and system in mobile phone - Google Patents

Description

  The present invention relates to an automatic e-mail reception process and control method in a mobile phone equipped with a short-range wireless communication function such as a non-contact IC.

  Mobile phones can communicate anywhere and anytime as long as they are within the reach of radio waves, but communication is not possible in places where radio wave propagation is poor, such as in the subway, or during high-speed movements such as riding on the Shinkansen. Is difficult to carry out stably.

  For example, when an e-mail addressed to the mobile phone arrives at the server, when the e-mail notification is received from the server to the mobile phone, the mobile phone performs a mail receiving process. When an e-mail addressed to a mobile phone that is in an environment where communication cannot be performed stably due to a bad arrival arrives at the e-mail server, the e-mail server and mobile phone base station notify the mobile phone of the incoming e-mail. In some cases, email delivery fails.

  In such a case, e-mail arrival notification is not performed from the server to the mobile phone thereafter. For this reason, the mobile phone user inquires of the server whether mail has been accumulated, and after moving to an environment in which the wireless state is restored and communication can be performed stably, the user can manually send e-mails. It was necessary to perform a receiving operation and receive an e-mail, which was troublesome for the user.

  In order to solve such a problem, for example, in Patent Document 1, a portable mail terminal is provided with a radio wave monitoring unit that appropriately monitors a radio wave state, and the radio wave monitoring unit is received during or during reception of an e-mail. If it detects that the radio wave condition is poor, stop or stop receiving e-mails, periodically monitor the radio wave condition, and then detect when the radio wave condition is good. A technique is disclosed in which an email can be automatically received without bothering the user even if the radio wave condition is poor by making a request to resend the email that has been interrupted.

  In recent years, in the public places such as trains and hospitals, when radio waves are transmitted in the dark, burst waves have started to be regarded as a problem for medical devices such as cardiac pacemakers, and have adverse effects such as errors. Therefore, entrance and exit gates with wireless communication terminal devices or non-contact type IC card reader / writers capable of short-range wireless communication such as Bluetooth and infrared are provided at the entrance and exit of such places, When a telephone passes through an entrance gate, for example, a manner mode is set for a cellular phone by communicating with the wireless communication terminal device or non-contact type IC card reader / writer capable of short-range wireless communication. Various techniques for automatically restraining the transmission of radio waves have been proposed in the past (Patent Documents 2 to 3, etc.).

  For example, in Patent Document 2, in a mobile phone provided with a non-contact IC card unit that enables use of a predetermined service by performing wireless communication with an external terminal device, when the mobile phone passes an entrance gate, The contactless IC card unit sets a manner mode for a mobile phone by performing wireless communication with the external terminal device, and the contactless IC card unit performs wireless communication with the external terminal device when passing through the exit gate. By doing so, the manner mode set in the mobile phone is canceled.

  According to the technique described in Patent Document 1, it is possible to determine that the wireless state has been recovered by the mobile phone performing wireless level measurement, and to automatically start the e-mail receiving process. If the radio wave condition deteriorates after resumption, the e-mail reception process must be interrupted again. In particular, when traveling at high speeds such as when riding on the Shinkansen, even if the wireless status is good and the email reception process starts, it immediately shifts to an environment where the wireless status is poor and the email reception fails. There is a possibility of falling into a magnificent tour. In addition, since a mail retransmission request is made each time, there is a possibility that power is wasted.

  Further, even when the manner mode is set by the technique described in Patent Document 2, it is possible to receive an email. For example, when an email is received in a state where the manner mode is set. When the environment is such that the wireless state of the place is poor and stable communication cannot be performed, it can be easily detected by detecting that the wireless state has been restored as in the technique described in Patent Document 1 above. When a re-transmission request for received mail is repeated, radio waves are transmitted from the mobile phone each time, and there is a risk of adversely affecting surrounding medical devices.

  FIG. 1 is a block diagram of a mobile phone showing an embodiment of the present invention. In this embodiment, a non-contact type IC card reader / writer provided at a ticket gate or the like as a short-range wireless function for detecting entry or exit to a predetermined area where the wireless state is not good or the manner mode needs to be set. A non-contact IC capable of communicating with the device is mounted.

  The mobile phone according to the present embodiment is connected to the wireless unit 12, the audio processing unit 13, the audio input / output unit 14, the memory 18, the display unit 19, the operation unit 20, and the non-contact IC 21 with the control unit 15 as the center. It is configured. The received wave received by the transmission / reception antenna 11 for the mobile phone is demodulated by the radio unit 12 and subjected to processing such as decoding by the audio processing unit 13, and the received received sound is output from the audio input / output unit 14 and is received by the user. To be told.

  The audio processing unit 13 and the radio unit 12 also have a function of performing processing such as encoding and modulation of audio to be transmitted input from the audio input / output unit 14 and transmitting from the transmission / reception antenna 11. Further, the wireless unit 12 is also used for signal transmission / reception during e-mail and Internet browsing. Since the configuration and operation related to communication of these mobile phones are well known, detailed description thereof will be omitted.

  The control unit 15 is a core for executing the functions of the mobile phone. In this embodiment, commands and data are transmitted between the e-mail control unit 16 that controls transmission / reception, storage, and reading of e-mails and the non-contact IC 21. A non-contact IC control unit 17 that performs transmission and reception is included. The memory 18 is a memory for storing a memory dial or the like. In this embodiment, the memory 18 is an area for storing information indicating that there is mail stored in the server.

Data is transmitted to and received from the external terminal 26 via the antenna 25. A reader / writer 27 included in the external terminal is for exchanging commands and data with the non-contact IC 21 mounted on the mobile phone. For example, in the present embodiment, the external terminal 26 is provided at a ticket gate of a train station, and can also be used as a terminal for reading a boarding ticket and commuter pass.

  FIG. 2 is a schematic diagram for explaining an automatic e-mail receiving method by the mobile phone of the present embodiment equipped with a non-contact IC.

  In FIG. 2, it is assumed that the area where the wireless state is poor is in a station premises or on a train, and the mobile phone is placed in any state from state 1 to state 3 described later. The entrance gate 2 and the exit gate 3 are, for example, ticket gates at stations. These entrance / exit gates are equipped with the functions of the external terminal 26 shown in FIG. 1, and provide services such as checking train tickets and commuter passes, and allowing users to enter and exit the area. is doing.

  The user enters from the entrance gate 2 and exits from the exit gate 3 using the mobile phone 1 equipped with a non-contact IC. State 1 is an initial state and is a state before the mobile phone 1 enters the area from the entrance gate 2. In state 1, there is no problem in the wireless state, and voice conversation and e-mail transmission / reception can be executed without any problem. From this state 1, when the non-contact IC 21 mounted on the mobile phone 1 is used to pass through the entrance gate 2, the mobile phone 1 is placed in a poorly wireless space such as a station premises or a train (state 2 )

  The area of state 2 is a place where radio waves are difficult to reach, such as a subway or a high-speed movement while riding on the Shinkansen, and a place where communication by a mobile phone cannot be performed stably. In this state 2, it is assumed that the e-mail server has not received the e-mail notification for the e-mail, or has arrived, but has failed to receive the e-mail because the wireless state is poor. In this state, if the train eventually arrives at the destination, and passes through the exit gate 3 using the non-contact IC 21 mounted on the mobile phone 1 in the same manner as when passing through the entrance gate 2, the mobile phone 1 detects that it has passed the exit gate 3 from the mounted non-contact IC 21, and enters state 3.

  As a result, the e-mail control unit 16 of the mobile phone 1 determines that the mobile phone 1 has escaped from a place where radio waves are difficult to reach, such as when traveling on the subway or the Shinkansen, and the wireless state has become stable. An inquiry is made to the e-mail server, and the control for receiving the e-mail that has failed to be received is automatically started. When the reception of the mail stored in the electronic mail server is completed, the state returns to state 1.

  FIG. 3 is a flowchart showing an operation example of the mobile phone when the mobile phone 1 in FIG. 2 returns from the state 2 to the state 1 via the state 3. The operation of this embodiment will be described below with reference to FIGS.

  When the mobile phone 1 of this embodiment equipped with a non-contact IC is entering an area with poor radio conditions such as a station yard or a train from the entrance gate 2, an e-mail addressed to the mobile phone 1 from a mail server When an incoming call notification is received, the reception of all the e-mails that have received the incoming call notification may not be successful, and the e-mail incoming call notification itself may not be received.

  When the non-contact IC control unit 17 of the mobile phone 1 receives the incoming mail notification from the mail server after detecting that the mobile phone 1 has shifted to the state 2 by the non-contact IC 21, the e-mail control unit 16 The mail acquisition request is transmitted once through the terminal 12, for example, and when the mail is successfully received, the received mail is stored in the built-in memory, or the mail acquisition request is not performed, and appropriate control can be performed. It is.

  After detecting that the mobile phone 1 has shifted to the state 2, the non-contact IC control unit 17 monitors whether or not the mobile phone 1 has passed the exit gate 3 (S 1). When the contact IC 21 detects that the mobile phone 1 has passed the exit gate 3 (S1-YES), the information is sent to the e-mail control unit 16. Receiving this information, the e-mail control unit 16 requests the mail server whether or not there is a server stored mail addressed to the mobile phone via the wireless unit 12, thereby requesting delivery of unreceived mail (S2). The mail delivered from the server according to this request is received (S3).

  According to the present embodiment, even when the mobile phone 1 is in an area where the wireless state is poor, even when it is not possible to receive an incoming e-mail notification addressed to the mobile phone 1 from the mail server, When the mobile phone 1 returns to a good wireless area, the mail server is always inquired whether there is server-stored mail addressed to this mobile phone, so mail can be sent automatically and reliably without bothering the user. Can be received.

  FIG. 4 is a timing chart showing a second embodiment of the mail transmission control procedure performed between the mobile phone and the electronic mail server (including the base station) when the mobile phone 1 in FIG. It is a chart.

  In the embodiment shown in FIG. 3 above, when the mobile phone 1 returns to a good wireless state, the mail server is unconditionally inquired whether there is a server stored mail addressed to this mobile phone. In the embodiment, in a state 2 in which the mobile phone 1 cannot stably receive e-mails, when a mail arrival notification addressed to itself is received from the mail server, a mail acquisition request is transmitted to the mail server once. When a mail distributed from the mail server can be received in response to a mail acquisition request, the received mail is stored in a built-in memory.

  On the other hand, when mail reception from the mail server in response to the mail acquisition request has failed, no further mail acquisition request is made, and the fact that the mail that failed to receive exists in the mail server is stored in the internal memory. deep. Then, when it is detected that the mobile phone 1 has exited from the restricted area after passing through the exit gate 3, the acquisition request for the mail that has failed to be received is transmitted to the mail server again with reference to the internal memory. Thus, the electronic mail is automatically received.

  In the embodiment shown in FIG. 4, when the mobile phone 1 in the state 2 that cannot stably receive an e-mail receives a mail arrival notification addressed to itself from the mail server, it does not make a mail acquisition request and is addressed to itself. Is stored in the built-in memory, and when it is detected that the mobile phone 1 has exited from the restricted area through the exit gate 3, the internal memory is referred to An e-mail may be automatically received by sending an e-mail acquisition request to the e-mail server.

  FIG. 5 is a flowchart showing an example of mail acquisition operation from the state 2 to the state 1 when the embodiment shown in FIG. 4 is added to the flowchart shown in FIG. The operation of this embodiment will be described below with reference to FIGS.

  When the mobile phone 1 of this embodiment equipped with a non-contact IC is entering an area with poor radio conditions such as a station yard or a train from the entrance gate 2, an e-mail addressed to the mobile phone 1 from a mail server When an incoming notification is received, an email acquisition request is sent to the email server once. When the email is successfully received, the received email is stored in the built-in memory. Instead, the fact that the mail that failed to be received exists in the mail server is stored in the built-in memory. Alternatively, it is stored in the built-in memory that a mail addressed to itself exists in the mail server without making a mail acquisition request.

  The non-contact IC control unit 17 of the mobile phone 1 monitors whether or not the mobile phone 1 has passed the exit gate 3 after detecting that the mobile phone 1 has shifted to the state 2 ( S1) When it is detected that the mobile phone 1 has passed the exit gate 3 (S1-YES), the information is sent to the e-mail control unit 16. Upon receiving this information, the e-mail control unit 16 determines whether “unconditional inquiry” is set by the user (S2), and when “unconditional inquiry” is set (S2-YES). Performs the same control as in the flowchart shown in FIG.

  On the other hand, if “unconditional inquiry” is not set (S2-NO), it is determined whether there is an unreceived mail addressed to the server by referring to the built-in memory (S3). If there is an unreceived mail addressed (S3-YES), an unreceived mail distribution request is made via the wireless unit 12 (S4), and the mail distributed from the server according to this request is received (S5). .

  In the present embodiment, the inquiry to the server after passing through the exit gate is executed by the user setting, and the mobile phone 1 recognizes that the server has stored mail without setting the “unconditional inquiry”. Since it is possible to make a mail delivery request to the server only in such a case, unnecessary communication can be suppressed.

  FIG. 6 is a timing chart showing a third embodiment of the mail transmission control procedure performed between the mobile phone and the electronic mail server (including the base station) when the mobile phone 1 in FIG. It is a chart.

  In the case of the embodiment shown in the flowchart shown in FIG. 5, when the mobile phone 1 returns to a good wireless state, the mail server is unconditionally inquired whether there is a server stored mail addressed to this mobile phone. By acquiring the unreceived mail addressed to you or storing in the internal memory that the mail addressed to you that could not be received in state 2 is stored in the internal memory When you return to, you get unreceived mail addressed to yourself from the server by referring to the built-in memory, but unnecessarily communicating with the mail server may cause unnecessary communication. The method of sending a mail delivery request to the server only when the telephone recognizes that there is stored mail on the server. Only if the Ba accumulation mail is recognized that there can not be automatically received mail, there may be a case, for example, you can not write automatic reception of which could not receive incoming call notification.

  Therefore, in the present embodiment, when the mobile phone 1 enters the restricted area and there is an incoming mail addressed to the mobile phone, and this mail cannot be delivered to the mobile phone 1, the mail server is addressed to the mobile phone 1. Is notified to the ticket gate (exit gate 3), and when the mobile phone 1 passes the ticket gate (exit gate 3), the non-contact IC 21 is connected from the external terminal 26 to the non-contact IC 21. The mobile phone 1 is notified that there is an unreceived mail, and the mobile phone 1 automatically sends a mail acquisition request addressed to itself to the mail server only when this notification is received. I have to.

  FIG. 7 is a flowchart showing an example of mail acquisition operation from the state 2 to the state 1 in the mobile phone 1 according to the present embodiment. Hereinafter, the operation of this embodiment will be described with reference to FIGS. 1 to 2 and FIGS. 6 to 7.

  When the mobile phone 1 of this embodiment equipped with a non-contact IC enters an area with poor radio conditions such as a station yard or a train from the ticket gate (entrance gate 2), the ticket gate (entrance gate 2) 1 notifies a mail server (including a base station) that 1 is in the area. When the mobile phone 1 is in the area and there is an incoming mail addressed to the mobile phone 1, the mail server transmits an incoming mail notification to the mobile phone 1.

  When the mobile phone 1 receives an incoming e-mail notification addressed to itself from the mail server, the mobile phone 1 sends a mail acquisition request to the mail server once. If the mail is successfully received, the received mail is stored in the mobile phone 1. Stored in memory. If the mail reception fails, the mail server sends a notification that undelivered mail addressed to the mobile phone 1 is accumulated to the ticket gate (exit gate 3). The ticket gate (exit gate 3) stores this notification in the memory in association with the mobile phone 1, and monitors the mobile phone 1 passing through the ticket gate (exit gate 3).

  When the mobile phone 1 is in the area (state 2) and an incoming mail is sent to the mobile phone 1, the mail server does not send an incoming mail notification to the mobile phone 1, Only the (exit gate 3) may be notified that undelivered mail addressed to the mobile phone 1 is accumulated.

  On the other hand, the non-contact IC control unit 17 of the mobile phone 1 monitors whether or not the mobile phone 1 has passed the exit gate 3 after detecting that the mobile phone 1 has shifted to the state 2. When it is detected that the mobile phone 1 has passed through the exit gate 3 (S1-YES), whether or not a notification that there is mail stored in the server is received from the exit gate 3 (S2), and when the notification that the stored mail addressed to the server is in the server is received from the exit gate 3 (S2-YES), the information is sent to the electronic mail control unit 16. Upon receiving this information, the e-mail control unit 16 makes a delivery request for unreceived mail to the server via the wireless unit 12 (S4), and receives mail delivered from the server in accordance with this request (S5).

  According to the present embodiment, when passing through the ticket gate (exit gate), the information that the server accumulated mail is present is received from the ticket gate, and an email distribution request is sent to the server based on the information. Since it is transmitted, it is not necessary to make unnecessary inquiries to the server, and it is possible to reliably make a mail delivery request to the server without performing useless communication.

  In each of the above embodiments, a non-contact type IC card reader / writer is arranged at the entrance gate and the exit gate, and the mobile phone 1 is equipped with a non-contact IC, whereby the mobile phone 1 and the entrance gate and the exit gate are connected. Although short-distance wireless communication is performed between them, as short-distance wireless communication means, wireless communication terminal devices capable of short-distance wireless communication such as Bluetooth and infrared are arranged at the entrance and exit of the restricted area, and the mobile phone 1 In addition, it is possible to adopt a configuration having a short-range wireless communication function capable of communicating with a wireless communication terminal device using Bluetooth, infrared rays, or the like.
