Description

  The present invention relates to a portable wireless terminal having a function for supporting waiting between individuals.

  Conventionally, when waiting is performed, a meeting place and a meeting time are notified between individuals, and the parties are visually recognized. For this reason, when the meeting place is crowded with people such as a station or the designated meeting place is abstract, there is a problem that even if the other party is nearby, it is not noticed.

As a method for solving this problem, one user has a portable transmission device that transmits a specific code signal, and the other user has a reception device that receives radio waves from the transmission device. There is a technique for identifying a code and identifying the position of the other party from the direction of arrival of radio waves. (For example, Patent Document 1)
Japanese Patent Laid-Open No. 2-226821

  However, in Patent Document 1, it is necessary to set a specific code in advance in both cases, and there is a problem that, for example, in the case of persons meeting for the first time, the specific code must be notified to the other party.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to facilitate setting of waiting support by a portable wireless terminal even if they meet for the first time.

For example, the present invention is a portable wireless terminal having a local communication function for directly wirelessly communicating with a counterpart terminal, and a specific code is generated by random numbers or keyed when a predetermined specific operation is performed A specific code generating means having a key code as a specific code; a specific code notifying means for notifying a specific code generated by the specific code generating means to a counterpart terminal; and a specific code receiving means for receiving a specific code generated by the counterpart terminal Specific call signal intermittent transmission means for intermittently transmitting a specific call signal including the specific code generated by the own terminal and the specific code generated by the counterpart terminal in a local communication mode; and the specific call from the counterpart terminal Specific call signal monitoring means for monitoring the signal, and the specific call signal monitoring means detects a specific call signal from the counterpart terminal. Or when a response signal from the partner terminal to the specific call signal transmitted by the terminal is detected, a message indicating that the communication partner exists in an area where local communication is possible is displayed. .

  ADVANTAGE OF THE INVENTION According to this invention, even if it meets for the first time, the specific code | cord | chord concerning waiting can be shared mutually by simple operation, and a flexible waiting assistance terminal can be provided.

  Embodiments of the present invention will be described below with reference to the drawings. In addition, the same reference number is given to substantially the same site | part, and description is not repeated.

  First, the system configuration of the present invention will be described with reference to FIG.

  The present invention is based on the portable radio terminal 1-1 and portable radio terminal 1-2 (hereinafter referred to as counterpart terminal 1-2) of the present invention connected to the radio base station 3-1 and the radio base station 3-2. The mobile wireless terminal 1 is a wireless mobile phone and has a voice call function. Further, when the portable wireless terminal 1 enters a certain distance range (for example, 100 m), local communication between terminals becomes possible.

  Here, the local communication means a communication form capable of one-to-one ad hoc communication (hereinafter referred to as inter-terminal local communication) using a communication form such as a transceiver, wireless LAN, ZigBee, Bluetooth, pager, or the like. .

  The waiting support according to the present invention includes two processes of waiting setting for performing waiting support in advance and waiting support for actually performing waiting support.

  During the call, the other party is notified of the meeting place, and when the portable wireless terminal 1-1 is operated to set the meeting, the portable wireless terminal 1-1 generates a waiting ID in its own terminal, and the generated waiting ID is set to DTMF. (Dual Tone Multi Frequency) is converted, superimposed on the voice during a call, and sent to the partner terminal 1-2. Receiving the meeting ID, the partner terminal 1-2 stores the meeting ID and ends the meeting setting.

  Here, the waiting ID is a common ID used as a search key when waiting support is performed in the portable wireless terminal 1-1 and the counterpart terminal 1-2, and means the specific code described above.

  Next, the mobile wireless terminal 1-1 moves to the meeting place, and when the operation for starting the meeting support is performed, the portable wireless terminal 1-1 starts transmitting the local beacon including the meeting ID and the local beacon of the meeting ID. Wait for reception. When the partner terminal 1-2 receives the local beacon, it confirms the waiting ID and displays the distance to the partner from the received radio wave intensity. And when it approaches the range which the other party can visually recognize (for example, 3 m), this is further displayed that it has approached the vicinity. Then, when the user performs a waiting end operation, the waiting support is ended.

  Next, functional blocks of the present invention will be described with reference to FIG.

  The portable radio terminal 1 includes a terminal control unit 101, a voice input / output unit 102, a microphone 103, a speaker 104, a display control unit 105, a display 106, a key input unit 107, an operation key 108, a radio unit 121, and a radio base station communication control unit. 122, a local communication control unit 123, an antenna 124, a radio wave intensity monitoring unit 125, a meeting ID setting unit 141, a meeting setting storage unit 142, and a meeting ID detection unit 143.

  The terminal control unit 101 includes a voice input / output unit 102, a display control unit 105, a key input / output unit 107, a waiting setting storage unit 142, a waiting setting unit 141, a radio wave intensity monitoring unit 125, a local communication control unit 123, and a radio base station communication control. Connected to the unit 122 and the meeting ID detection unit 143, and controls the overall processing of the portable wireless terminal, and controls other connected block units.

  The audio input / output unit 102 is a codec that is connected to the microphone 103 and the speaker 104 and performs overall audio control. Specifically, when voice data is received from the local communication control unit 123 or the wireless base station communication control unit 122 via the terminal control unit 101 during a call, the voice data is decoded and output to the speaker 104. Further, when voice input is detected from the microphone 103 during a call, the voice data is encoded into voice data, and the generated voice data is sent to the local communication control unit 123 or the radio base station communication control unit 122 via the terminal control unit 101. hand over.

  The display control unit 105 is connected to the display 106 and displays the display data sent from each block on the display 106 via the terminal control unit 101.

  When the key input unit 107 detects a user key operation from the operation keys 108, the key input unit 107 passes the key data to the terminal control unit 101.

  When receiving data from the wireless base station communication control unit 122, the data is converted into a wireless signal for public wireless communication and transmitted through the antenna unit 124.

  In addition, during the call, when the DTMF converted waiting data is sent from the wireless base station communication control unit 122, it is superimposed on the voice of the call and transmitted.

  Here, the waiting data means predetermined dial signal enumeration data related to waiting support such as waiting ID, and the details will be described later.

  The wireless unit 121 processes the overall wireless control.

  The radio base station communication control unit 122 controls the radio base station communication. Further, when receiving an instruction to send the waiting data together with the waiting data from the terminal control unit 101, the received waiting data is converted into a DTMF signal and passed to the radio unit 121.

  The local communication control unit 123 controls local communication. When receiving a local beacon transmission instruction from the terminal control unit 101 together with the waiting ID, a local beacon is generated, and in cooperation with the wireless unit 121, periodic local beacon transmission is started.

  Upon receiving a monitoring instruction from the terminal control unit 101, the radio wave intensity monitoring unit 125 monitors the wireless unit 121, monitors reception of a wireless signal in local communication, and cooperates with the waiting ID setting unit 141 and the local communication control unit 123. When the wireless signal of the local beacon from the mobile wireless terminal 1 is detected, it is searched whether the detected local beacon includes the waiting ID. If the waiting ID is included, the waiting ID is extracted and received. The radio field intensity of the radio signal with the waiting ID is measured. Then, the waiting ID and the measured radio wave intensity are passed to the terminal control unit 101.

  The meeting ID setting unit 141 generates a meeting ID using a random number when receiving an instruction for generating a meeting ID from the terminal control unit 101, and stores it in the meeting setting storage unit 142.

  The meeting setting storage unit 142 stores various meeting data used for meeting setting, the meeting ID generated by the meeting ID setting unit 141, or the meeting ID passed from the local communication control unit 123.

  The meeting ID detection unit 143 monitors the meeting data transmitted to the local communication control unit 123 and the wireless base station communication control unit 122 via the wireless unit 121. When meeting data is detected, the detected meeting ID is passed to the terminal control unit 101.

  Next, a process for setting the waiting of the portable wireless terminal during a call will be described using the flowchart of FIG. In addition, this flow starts from a state in which the waiting portable wireless terminal 1-1 establishes a call with the counterpart terminal 1-2 and is in a call.

  First, the terminal control unit 101 detects whether a waiting setting start operation from the user is detected (S301), or waits for reception of a waiting setting start signal from the counterpart terminal 1-2 (S306). When there is an operation for starting the waiting setting from the user (S301: YES), a waiting setting start signal for notifying that the waiting setting process has been started is transmitted to the counterpart terminal 1-2 (S302).

  Specifically, when the key input unit 107 detects a user's waiting setting start operation from the operation key 108 (for example, pressing the operation key “489”), the terminal control unit 101 sets the waiting setting from the waiting setting storage unit 142. The data of the start signal (for example, “## 123”) is read out and transferred to the radio base station communication control unit 122 and the transmission of the waiting setting start signal is instructed. Upon receiving the instruction, the wireless base station communication control unit 122 cooperates with the wireless unit 121 to perform DTMF conversion on the received waiting setting start data, and superimposes it on the voice during the call as a waiting setting start signal via the antenna 124. To the counterpart terminal 1-2.

  The data of the waiting setting start signal is a kind of waiting data, and means dial data that is determined in advance and can be converted into DTMF. The operation for starting the waiting setting may be an operation key (for example, a “decision key” of the portable wireless terminal) assigned in advance during a call.

  Then, it waits for reception of a waiting setting response signal from the counterpart terminal 1-2 (S303). When the meeting setting response signal is received (S303: Yes), a meeting ID is generated and stored in the own terminal (S304), and the generated meeting ID is transmitted to the partner terminal 1-2 (S305). When the waiting setting response signal is not received from the counterpart terminal 1-2 (S303: No), the process returns to S301.

  Specifically, the meeting ID detection unit 143 monitors the wireless base station communication control unit 122 and, when detecting voice data that has been DTMF converted into voice data during a call, extracts the meeting data from the data and performs terminal control. To the unit 101. The passed terminal control unit 101 compares the extracted waiting data with the waiting data stored in advance in the waiting setting storage unit 142, and recognizes that the data of the waiting setting response signal has been detected. Then, the terminal control unit 101 instructs the meeting ID setting unit 141 to generate a meeting ID. Upon receiving the instruction, the waiting ID setting unit 141 generates a waiting ID (for example, a 4-digit number such as “1 # 2 *”) using a random number function. The generated meeting ID is stored in the meeting setting storage unit 142 and also transferred to the terminal control unit 101. The passed terminal control unit 101 relays the meeting ID to the radio base station communication control unit 122 and instructs transmission of the meeting ID. The radio base station communication control unit 122 instructed to transmit the meeting ID performs DTMF conversion on the meeting ID received in cooperation with the wireless unit 121, and superimposes the meeting ID on the voice during the call via the antenna 124. Send to partner terminal 1-2.

  The case where the waiting setting response signal is not received is a case where, when not shown, when a waiting setting start signal is transmitted, a predetermined timer (for example, 30 seconds) is started and the waiting setting response signal cannot be received within the time. This means that the portable wireless terminal 1-1 determines that the partner terminal 1-2 is not permitted or does not have the waiting setting function in the partner terminal 1-2, and returns to S301.

  Next, when a waiting setting start signal is received from the counterpart terminal 1-2 (S306: Yes), it waits for a user's waiting setting permission operation (S307). Here, the case where the waiting setting start signal is received means that the partner terminal 1-2 has performed the waiting setting start operation previously described in S301 and has received the waiting setting start signal from the partner terminal 102.

  Specifically, the meeting ID detection unit 143 monitors the wireless base station communication control unit 122 and, when detecting voice data that has been DTMF converted into voice data during a call, extracts the meeting data from the data and performs terminal control. To the unit 101. The transferred terminal control unit 101 compares the extracted waiting data with the waiting data stored in advance in the waiting setting storage unit 142, and recognizes that the data of the waiting setting start signal has been detected. Then, the terminal control unit 101 instructs the display control unit 105 to display the waiting setting. Receiving the instruction, the display control unit 105 displays a request for waiting from the counterpart terminal 1-2 on the display 106, and waits for a user operation.

  Next, when there is a waiting setting permission operation from the user (S307: Yes), a waiting setting response signal is transmitted as a permission response to the waiting setting start signal (S308). If the waiting setting permission operation cannot be detected from the user (S307: No), the process returns to S301.

  Specifically, when the key input unit 107 detects a user's waiting setting permission operation from the operation key 108 (for example, pressing the operation key “114”), the terminal control unit 101 waits from the waiting setting storage unit 142. Data of the setting response signal (for example, “## 456”) is read out and transferred to the radio base station communication control unit 122, and the transmission of the waiting setting response signal is instructed. Upon receiving the instruction, the radio base station communication control unit 122 cooperates with the radio unit 121 to perform DTMF conversion on the data of the received waiting setting response signal, and superimposes it on the voice during the call as the waiting setting response signal. To the counterpart terminal 1-2. The data of the waiting setting response signal is a kind of waiting data, and means dial data that is determined in advance and can be converted into DTMF. The waiting setting permission operation may be an operation key (for example, a “decision key” of the portable wireless terminal) assigned in advance when the waiting setting start signal is received.

  Further, the case where the waiting setting permission operation cannot be detected in S307 means that when a waiting setting start signal is received (not shown), a predetermined timer (for example, 30 seconds) is started, and the waiting setting permission operation from the user within the time. Cannot be detected, it is determined that there is no waiting support function or setting is not permitted, and the process returns to S301.

  Next, it waits for reception of a meeting ID from the partner terminal 1-2 (S309). When the meeting ID is received (S309: Yes), the meeting ID is stored (S310), and the process proceeds to S311. When the meeting ID is not received (S309: No), the process returns to S301.

  Specifically, the meeting ID detection unit 143 monitors the wireless base station communication control unit 122 and, when detecting voice data that has been DTMF converted into voice data during a call, extracts the meeting data from the data and performs terminal control. To the unit 101. The passed terminal control unit 101 collates the extracted waiting data with the waiting data stored in the waiting setting storage unit 142 in advance, and recognizes the waiting data as the waiting ID because the corresponding waiting data cannot be detected. The terminal control unit 101 stores the detected meeting ID in the meeting storage unit 142.

  The case where the meeting ID is not received means that although not shown, a predetermined timer (for example, 5 seconds) is started and the meeting ID is not received within the time, and when the meeting ID is not received, The sending of the waiting setting response signal is repeated at a predetermined timer interval, and the sending of the waiting setting response signal is stopped when the release operation by the user or the call ends.

  Further, it is determined whether there is a waiting timer setting for automatically starting the waiting support operation described in FIG. 4 (S311). If there is a waiting setting (S311: Yes), a waiting timer is started (S312), and this flow ends. If there is no setting (S311: No), this flow is terminated as it is.

  Specifically, although not shown, the portable wireless terminal 1 has a waiting timer function linked to a time function, and can register a waiting time. The terminal control unit 101 determines whether or not a waiting time is registered in the waiting timer function. If the waiting time is registered, the terminal control unit 101 instructs activation of the waiting timer, and the waiting timer function starts its operation. Details will be described later with reference to FIG. If it is not registered, nothing is done.

  Next, the process of the actual meeting support operation when the portable wireless terminal 1-1 and the partner terminal 1-2 complete the waiting setting will be described using the flowchart of FIG.

  This flow starts from a state in which the portable wireless terminal 1-1 and the partner terminal 1-2 both store the meeting ID and the meeting setting is set.

  First, the user of the portable wireless terminal 1-1 detects the partner presence confirmation operation (S401), or waits for the set time of the waiting timer set in FIG. 3 (S402).

  When the partner presence confirmation operation is detected (S401: Yes) or when the set waiting timer reaches the set time (S403: Yes), it is determined that the waiting support is started, and the terminal control unit 101 stores the waiting setting. The meeting ID stored in the unit 142 is read, a local beacon including the meeting ID is generated, and transmission of the local beacon is started (S403).

  Specifically, when the key input unit 107 detects a partner presence confirmation operation for searching for the partner terminal 1-2 using local communication from the operation key 108 (for example, pressing “314” and the operation key), Alternatively, when the waiting timer being activated explained in FIG. 3 reaches the set time, the terminal control unit 101 reads the waiting ID from the waiting setting storage unit 142, passes the waiting ID to the local communication control unit 123, and starts local beacon transmission. Instruct. Upon receiving the instruction, the local communication control unit 123 generates a beacon including the received waiting ID, and starts transmission as a local beacon via the wireless unit 121 and the antenna at a certain transmission timing (for example, 5 seconds).

  Here, the set time of the waiting timer means a time before the waiting time (for example, 30 minutes before).

  Next, it waits for reception of a local beacon (S404). When a local beacon is received (S404: Yes), it is determined whether or not the received meeting ID matches the meeting ID of the partner terminal 1-2 stored in the meeting setting of FIG. 3 (S405). When the local beacon is received from the counterpart terminal 1-2 (S404: Yes and S405: Yes), the radio field intensity of the received local beacon is measured (S407). Then, the estimated distance to the partner terminal 1-2 is calculated from the measured radio wave intensity, and the estimated distance to the partner terminal 1-2 is displayed on the display 106 (S408).

Specifically, the meeting ID detection unit 143 monitors the local communication control unit 123 and, when detecting the meeting ID in the received local beacon, extracts the meeting ID from the local beacon and passes it to the terminal control unit 101. The passed terminal control unit 101 compares the extracted waiting ID with the waiting ID stored in the waiting setting storage unit 142, reads out the radio wave intensity of the local beacon from the radio wave intensity monitoring unit 125, and receives the counterpart terminal 1 -Estimated distance to -2. Then, the calculated estimated distance is passed to the display control unit 105 and displayed. Upon receiving the instruction, the display control unit 105 displays the estimated distance on the display 106 (for example, “the distance to the meeting partner is about 50 m”).
When the local beacon is not received (S404: No), or when the waiting IDs do not match (S405: No), a message indicating that the partner terminal 1-2 is not present nearby is displayed (for example, “outside partner range” is displayed on the display). "Is displayed) (S406), and the process proceeds to S411.

  Specifically, the terminal control unit 101 instructs the display control unit 105 to display “out of service area” when a local beacon is not detected from the local communication control unit 123 for a certain time (for example, 5 seconds). . Upon receiving the instruction, the display control unit 105 displays “out of service area” on the display 106.

  Next, when the estimated distance from the partner terminal 1-2 is displayed in S408, it is determined whether the estimated distance from the partner terminal 1-2 is equal to or less than a threshold (for example, within 3 m) (S409). Alternatively, it is determined whether or not the user has stopped the meeting support (S411).

  When the distance to the partner is close (S409: Yes), the fact that the partner terminal 1-2 is in the vicinity is displayed (for example, “arrived” is displayed on the display) (S410).

  If there is a waiting support stop operation (S411: Yes), transmission of the local beacon is stopped (S412), the set waiting ID is deleted (S413), and this flow ends.

  Specifically, when the estimated distance of the local beacon passed from the radio wave intensity monitoring unit 125 is equal to or less than a predetermined value (3 m), the terminal control unit 101 notifies the display control unit 105 of “arrival”. Instructed to display “Done”. Upon receiving the instruction, the display control unit 105 displays “Arrived” on the display 106. When the key input unit 107 detects an operation of stopping the user's waiting support from the operation key 108 (for example, pressing the “end call button”), the terminal control unit 101 instructs the local communication control unit 123 to stop transmission of the local beacon. In response to this, the local communication control unit 123 stops the transmission of the local beacon. Further, the terminal control unit 101 instructs the meeting setting storage unit 142 to delete the meeting ID, and the meeting setting storage unit 142 that has received the instruction deletes the meeting ID.

  The waiting support process using the voice call function has been described above.

  In the present embodiment, when the mobile wireless terminal 1-1 is set for waiting, a waiting ID is generated, the generated waiting ID is notified to the partner terminal 1-2 via base station communication, and the waiting ID is set. Share When the meeting support is made, local beacons including the meeting ID are transmitted to the partner terminal 1-2, and when the local beacon is received, the reception is displayed.

Thus, the mobile radio terminal 1-1 is notified of waiting ID to the remote terminal 1-2, it is not necessary to set the pre-Me queuing ID. In addition, since the meeting ID is notified using another communication means, the meeting ID can be notified securely.

  Moreover, in this Embodiment, the portable radio | wireless terminal 1-1 demonstrated the method to produce | generate the production | generation method of waiting ID every time for every waiting setting using a random number.

  Thereby, since the waiting ID is changed every time, the confidentiality of the waiting ID can be improved.

  Further, in the present embodiment, a method has been described in which the meeting ID is DTMF converted and superimposed on the voice during a call.

  As a result, since the waiting ID is notified to the other terminal with the voice during the call, there is an effect that it is not necessary to newly set a communication path.

Moreover, in this Embodiment, the portable radio | wireless terminal 1 measures the field intensity of the received local beacon, estimates the distance with the other party terminal 1-2 from the measured field intensity, and displays this. Furthermore, when the estimated distance to the partner terminal 1-2 is equal to or less than a predetermined value , a message indicating that it is present in the vicinity is displayed.

  Thereby, at the time of meeting support, the user knows that the other party is approaching.

  Note that the waiting ID is DTMF-converted during a call and superimposed on the voice during the call, but the present application is not limited to this. For example, the meeting ID may be notified using other communication means such as mail or short mail during the waiting setting process in FIG. Accordingly, there is an effect that the waiting ID can be notified to the partner terminal 1-2 without being influenced by the communication environment during the call.

  Moreover, although the method for displaying on the display 106 that there is a request for waiting from the counterpart terminal 1-2 when receiving the waiting setting signal has been described, the present application is not limited to this. For example, the user may be notified using a transmission function such as a voice guidance / vibrator.

  In addition, a waiting ID is automatically generated using a random number and notified to the other party by a tone signal, but the present application is not limited to this. For example, the user may directly input an operation key (dial key) during a call to notify the partner terminal 1-2 of the input key as a waiting ID, or use the telephone number of the own terminal as a waiting ID. May be. In addition, if the partner has already set a waiting ID, the ID that has already stored the waiting ID may be reused, and the first partner may be generated and notified with a waiting ID other than the stored ID. . Furthermore, when a meeting ID is received, a response for rejecting it or a method for not responding may be used. This has the effect of avoiding the possibility of duplicate IDs generated by random numbers.

  Moreover, although the setting of the waiting timer in FIG. 3 has been described, the present application is not limited to this. For example, transmission of a local beacon may be started after notifying the meeting ID. As a result, there is an effect that it is not necessary for the partner confirmation operation or the user to set the waiting timer in advance.

  Moreover, although this support is complete | finished by the detection of waiting end operation by S411 of FIG. 4, this application is not limited to this. For example, in the determination of S409, it may be determined that the other party has been met when S404 to S410 are repeated for several tens of seconds. As a result, there is an effect that it is not necessary to perform a waiting end operation.

  Further, by eliminating the above-described partner confirmation operation and waiting end operation, the user can receive waiting support by any one of the waiting start operation and the waiting permission operation.

  In addition, instead of an e-mail address, the meeting ID is generated by a local terminal such as a random number, and the meeting ID is attached and transmitted when the meeting ID start mail / response mail is transmitted. When the meeting ID is received, the received meeting ID and the received ID are transmitted. The same effect can be obtained by storing the original address in association with each portable wireless terminal.

  In the present embodiment, the one-to-one waiting support has been described, but the present application is not limited to this. Of course, there may be a plurality. In this case, it can be realized by setting and storing a waiting setting for each partner terminal 1 and transmitting local beacons to all the partner terminals.

  In the present embodiment, a general wireless mobile phone has been described. However, the present application is not limited to this. For example, the present invention can be applied to any device that has a specific wireless communication function and can be carried, such as a pager, a PDA, or a mobile PC.
