[Operation example 1]
Next, an example of 遭 even-history storing process (hereinafter, the present example of "Operation Example 1".) Will be described.
In the first operation example, in order to perform a list display process (specific process) for displaying an encounter history list for the user to know who met at what time, an encounter history storage process is first performed. . In order to start the encounter history saving process, the user operates the key operation unit 120 to store the mobile phone number data (specific information) of the acquaintance of the user and other related information (name, E-mail address) is registered in the address book table of the internal memory 112. This registration processing method is not limited to a method in which the user manually operates the key operation unit 120, and any method can be used as long as the phone number data of the cellular phone of an acquaintance can be registered in the address book table. It may be. For example, a method of registering various information such as telephone number data of an acquaintance's mobile phone input by performing short-range communication with an acquaintance's mobile phone using the short-range radio communication unit 140 in the address book table, or wireless communication A method of registering various information such as telephone number data of an acquaintance's mobile phone received using the unit 113 in the address book table may be used. In the case of these methods, the short-range wireless communication unit 140 or the wireless communication unit 113 functions as the input unit 104.
Further, whether or not the encounter history saving process is performed in the mobile phone 10 is determined based on a user operation. That is, when the user performs a predetermined key operation on the key operation unit 120 and the operation mode for performing the encounter history storage process is set, the setting is changed to the operation mode in which the encounter history storage process is not performed thereafter. Until it is done, the encounter history saving process is performed.

FIG. 1 is a flowchart showing a flow of encounter history saving processing in the first operation example.
FIG. 4 is a sequence flow diagram showing a communication sequence of encounter history saving processing in the first operation example.
When the operation mode in which the mobile phone 10 performs the encounter history saving process is set, first, the mobile phone 10 performs an inquiry broadcast process (S1). Specifically, the control unit 111 functions as a response request transmission unit in cooperation with the short-range wireless communication unit 140, and intermittently transmits IQ packets (response requests) from the short-range wireless communication unit 140. . Then, the control unit 111 functions as a response receiving unit in cooperation with the short-range wireless communication unit 140 and waits for an FHS packet (response) for an IQ packet transmitted from another mobile phone. Here, another mobile phone equipped with a short-range communication means adopting the same Bluetooth short-range wireless communication method as the mobile phone 10 has entered the communicable range of the short-range communication means 103 of the mobile phone 10. In this case, the other mobile phone performs the inquiry scan process and receives the IQ packet. Then, the other mobile phone performs an inquiry response process in which an FHS packet is transmitted as a response to the received IQ packet. When the mobile phone 10 receives the FHS packet (S2), the mobile phone 10 performs a calling process for establishing a communication link (piconet) with another mobile phone that is the transmission source of the FHS packet. Specifically, the mobile phone 10 transmits an ID packet to the other mobile phone, and receives the same ID packet transmitted from the other mobile phone as a response. The mobile phone 10 that has received the ID packet transmits an FHS packet, and when this is received by the other mobile phone, the ID packet is transmitted from the other mobile phone as a confirmation of the reception. Received. Through the above processing, intra-piconet synchronization is established between the mobile phone 10 and the other mobile phone, a communication link is established (S3), and data communication is possible between them.

  In this way, when a communication link is established with another mobile phone that has entered the communicable range of the short-range communication means 103 of the mobile phone 10, the control unit 111 of the mobile phone 10 includes the short-range wireless communication unit 140. The short-distance wireless communication unit 140 transmits a telephone number acquisition request to the other mobile phone. Other mobile telephones that have received this telephone number acquisition request send their telephone number data (specific information) to the mobile telephone 10 as a response. The control unit 111 of the mobile phone 10 functions as specific information receiving means in cooperation with the short-range wireless communication unit 140 and receives the telephone number data. As a result, the mobile phone 10 can acquire the telephone number data of other mobile phones that have entered the communicable range of the short-range communication means 103 (S4).

  The control unit 111 of the mobile phone 10 that has acquired the phone number data of the other mobile phone next determines whether the phone number data is registered in the address book table in the internal memory 112 ( S5). In this determination, when it is determined that it is not registered in the address book table, the control unit 111 makes an inquiry to search for another mobile phone while maintaining the communication link with the other mobile phone. Broadcast processing is performed (S1). On the other hand, when the telephone number data registered in the address book table is acquired by repeating the processes of S1 to S5, the control unit 111 of the mobile phone 10 acquires date and time data from the clock unit 125 (S6). ). Then, the control unit 111 associates the acquired date and time data with the telephone number data as start time data, and registers it in the encounter history table (S7). This date / time data indicates the storage time of the telephone number data, but may indicate the reception time of the telephone number data.

  After the date / time data is registered in the encounter history table, the control unit 111 then functions as a determination unit in cooperation with the short-range wireless communication unit 140, and at the transmission source of the telephone number data registered in the encounter history table. It is determined whether another mobile phone has moved out of the communicable range of the short-range communication means 103 of the mobile phone 10 (S8). Specifically, the control unit 111 of the mobile phone 10 starts the link monitoring timer as shown in FIG. This timer is reset every time data is received from another linked mobile phone. The communication link is maintained while the mobile phone 10 receives a presence confirmation notification periodically transmitted from another mobile phone, but the other mobile phone is out of the communicable range of the mobile phone 10. When the mobile phone 10 moves, the mobile phone 10 cannot receive the presence confirmation notification. As a result, when the count value of the link monitoring timer exceeds a predetermined time, the control unit 111 of the mobile phone 10 determines that the other mobile phone has moved out of the communicable range and disconnects the communication link. (S9). Then, the control unit 111 acquires date / time data from the clock unit 125 (S10), associates the date / time data with the telephone number data as end time data, and registers the date / time data in the encounter history table (S11).

Table 1 below shows an example of the encounter history table. This example is recorded in the situation as shown in FIG. This situation is as follows. When the user (company employee) of the mobile phone 10 was talking with his colleague A (10:33), he decided to go for lunch together. So, I decided to invite Mr. B in the same time, promised to have lunch with Mr. B over the phone, and waited under the elevator. When the user went to the meeting place, Mr. B came a little later (11:55) following Mr. A (11:52). After a short walk, we had lunch at a reputable canteen. On the way home, I walked with Mr. C (12:40) when I was walking with 3 people, and 4 people went back to work together. Mr. C immediately returned to his desk (12:46), but the other three decided to smoke a cigarette in the smoking room. After smoking, another floor separated from Mr. B at work (12:52), but the user remembered the work and talked with Mr. A at his desk for about 10 minutes. Then I returned to my own job (13:05).

In the present embodiment, the control unit 111 calculates the encounter time (related information) from the start time to the end time, and also registers the encounter time in the encounter history table. In addition, the control unit 111 reads acquaintance name data (related information) corresponding to the telephone number data from the address book table, and also registers it in the encounter history table. In the present embodiment, the telephone number data is also registered in the encounter history table and the start time data and the like are registered in association with this, but if the start time data and the like are associated with the telephone number data, the telephone number data is not necessarily stored. It is not necessary to register the number data in the encounter history table. Therefore, an encounter history table as shown in Table 2 below may be used. In this case, the start time data or the like registered in the encounter history table is associated with the telephone number data registered in the address book table via the name data.

Next, a list display process using the encounter history table will be described.
FIG. 6 is a flowchart showing the flow of the list display process.
When the user of the mobile phone 10 performs a predetermined key operation for performing a list display on the key operation unit 120, the control unit 111 reads the today's encounter history table from the internal memory 112 (S21). Then, the control unit 111 outputs a command for displaying the encounter history list based on the read encounter history table on the liquid crystal display to the image processing unit 118 (S22). Upon receiving this command, the image processing unit 118 performs drawing processing for displaying the encounter history table image as shown in Table 1 or 2 on the liquid crystal display of the display unit 119 (S23). Thereby, the user who sees this encounter history list can know who met at what time today.
In addition to the information registered in the encounter history list, information registered in the address book table with reference to the address book table may also be displayed in the encounter history list.

In the first operation example, the case has been described in which the mobile phone 10 operates as a master and the other mobile phones operate as slaves, but the reverse is also possible. The flow of encounter history storage processing in this case is as shown in FIG. That is, the mobile phone 10 operating as a slave performs inquiry scan processing (S31), and waits for an IQ packet by inquiry broadcast processing performed by another mobile phone operating as a master. Here, another mobile phone equipped with a short-range communication means adopting the same Bluetooth short-range wireless communication method as the mobile phone 10 has entered the communicable range of the short-range communication means 103 of the mobile phone 10. In this case, the mobile phone 10 receives an IQ packet from another mobile phone (S32). Then, the cellular phone 10 performs an inquiry response process of transmitting an FHS packet as a response to the received IQ packet. When this FHS packet is received by the other mobile phone, the other mobile phone performs a calling process for establishing a communication link (piconet) with the mobile phone 10 that is the transmission source of the FHS packet, In-piconet synchronization is established between the mobile phone 10 and the other mobile phone, and a communication link is established (S3). The subsequent processing is the same as that described above.
In the first operation example, the case where both the start time data and the end time data are registered in the encounter history table has been described. However, only one of the time data may be registered.

  As described above, according to the first operation example, at the end of the day, the user performs a predetermined key operation on the key operation unit 120 of the mobile phone 10 to execute the list display process. Users can know if they have met.

[Operation example 2]
Next, another example of the encounter history storing process according to the embodiment of the present invention and the process using the encounter history table obtained thereby (hereinafter, this example is referred to as “operation example 2”) will be described.
In the second operation example, not only the time when the user of the mobile phone 10 meets an acquaintance but also the conversation at that time is recorded.
FIG. 8 is a flowchart showing the flow of the encounter history saving process in the second operation example.
In the mobile phone 10, as in the case of the operation example 1 described above, an acquaintance's mobile phone provided with a short-range communication means adopting the same Bluetooth short-range wireless communication method as the mobile phone 10 is used as the mobile phone 10. When the communication range of the short-range communication means 103 is entered, a communication link (piconet) is established with the acquaintance's mobile phone (S1 to S3). Then, the control unit 111 of the cellular phone 10 acquires the telephone number data of the acquaintance's cellular phone as in the case of the operation example 1 (S4), and the telephone number data is stored in the address book in the internal memory 112. It is determined whether it is registered in the table (S5).

  In this determination, if it is determined that it is registered in the address book table, the control unit 111 acquires date / time data from the clock unit 125 (S6), as in the case of the operation example 1, and uses this as start time data. Is associated with the telephone number data and registered in the encounter history table (S7). Furthermore, in this operation example 2, when it is determined that the information is registered in the address book table, the control unit 111 starts recording (S41). Specifically, the control unit 111 outputs a recording command to the sound processing unit 115. Thereby, the sound processing unit 115 outputs sound data obtained by encoding the sound input from the microphone 116 by a predetermined method to the control unit 111. The control unit 111 sequentially stores the sound data in the internal memory 112.

  Thereafter, as in the case of the first operation example, the control unit 111 causes the mobile phone of the acquaintance who is the transmission source of the telephone number data registered in the encounter history table to communicate with the short-range communication means 103 of the mobile phone 10. It is determined whether or not it has moved out of the possible range (S8). If it is determined that the mobile phone of the acquaintance has moved out of the communicable range, the communication link is disconnected (S9) and date / time data is obtained from the clock unit 125, as in the case of the first operation example. Acquired (S10), this date / time data is associated with the telephone number data as end time data and registered in the encounter history table (S11). Furthermore, in this operation example 2, when it is determined that the acquaintance's mobile phone has moved out of the communicable range of the short-range communication means 103 of the mobile phone 10, the control unit 111 stops recording (S42). Specifically, the control unit 111 outputs a recording stop command to the sound processing unit 115. As a result, the sound processing unit 115 stops outputting the sound data to the control unit 111. Then, the control unit 111 performs a process of storing the sound data recorded in the internal memory 112 as a data file (recording file), and associates address information indicating the storage location with the telephone number data, thereby generating an encounter history table. (S43).

Table 3 below shows an example of the encounter history table in the second operation example. This encounter history table
The same situation as the situation described in the above operation example 1 is assumed, and the address information item of the recording file is added to the encounter history table shown in Table 2 in the above operation example 1. In the example shown in Table 3 below, there are overlapping parts in the time zones where Mr. A, Mr. B, and Mr. C met, so the same recorded file (con_A_200311211152.mp3) Are associated.

Next, a recorded file reproduction process using the encounter history table will be described.
FIG. 9 is a flowchart showing the flow of the recorded file reproduction process.
In the recorded file reproduction process in the second operation example, first, the list display process is performed as in the first operation example (S21 to S23). As a result, the encounter history table image as shown in Table 3 above is displayed on the liquid crystal display of the display unit 119. However, in the displayed image, the address information of the corresponding recording file is embedded as link information in the file name image portion of the recording file (hereinafter referred to as “link image”). Therefore, the user can see who has met today by looking at the encounter history list, and by operating the key operation unit 120 and selecting a link image of the encounter history list, the user can meet the encounter history list. You can listen to conversations with other people.

  Specifically, when the user who has seen the encounter history list performs a predetermined key operation on the key operation unit 120 and a link image of the encounter history list is selected (S51), the operation signal is transmitted to the control unit. 111 is input. In response to this, the control unit 111 activates a reproduction application program for reproducing the recording file (S52). Then, the control unit 111 that executes the reproduction application program reads the recording file stored in the location specified by the address information embedded in the selected link image from the internal memory 112 (S53). Further, the control unit 111 reads the start time data and the end time data corresponding to the selected link image, specifies the location corresponding to the time indicated by the start time data as the playback start location, and the end time data. The location corresponding to the time indicated by is specified as the playback end location (S54). Then, the control unit 111 that executes the playback application program starts playback of the read recording file from the playback start point specified in S54 (S55). Thereafter, when the playback of the recording file reaches the playback end point specified in S54 (S56), the control unit 111 stops the playback of the recording file (S57). Even when the user performs a predetermined playback stop operation on the key operation unit 120, the control unit 111 stops playback of the recorded file.

  As described above, according to the second operation example, at the end of the day, the user performs a predetermined key operation on the key operation unit 120 of the mobile phone 10 to execute the recorded file reproduction process. The user can know whether or not he / she met, and can listen to the conversation when he / she met.

In the second operation example, the location corresponding to the time indicated by the start time data and the end time data is specified as the playback start location and the playback end location of the corresponding recording file. The recorded file is reproduced from the time when the communication range of the ten short-range communication means 103 is entered. However, in the present embodiment, the short-range communication means 103 employs a short-range wireless communication system using Bluetooth radio waves, and therefore the communicable range is about 10 m in radius. Therefore, it takes time until an acquaintance's mobile phone enters the communicable range and approaches the user of the mobile phone 10 and actually has a conversation. For this reason, if the recorded file is reproduced from the position corresponding to the start time data as in the second operation example, it takes time until the actual conversation portion is reproduced after the reproduction. Therefore, it is desirable to take measures to shorten the time from when the recorded file is reproduced until the actual conversation portion is reproduced.
As this measure, for example, it is detected that the mobile phone of an acquaintance is within a range (for example, a radius of about 3 m) that is closer than the communicable range of the short-range communication means 103 of the mobile phone 10, and corresponds to the detection time point. The playback is started from the location where the recording is performed, or the sound data of the recording file is analyzed to identify the location where the conversation portion starts, and the playback is started from that location. As another measure, for example, recording may be started when an acquaintance's mobile phone enters a range narrower than the communicable range. The communicable range is a range with a radius of about 10 m, but the recording start range may be a range of about 3 m. Further, recording may be started when the user performs a predetermined recording start operation. In this case, the recording start operation time may be registered in the encounter history table as data for specifying the playback start location in association with the telephone number data in which only the start time data is registered in the encounter history table.

  In the second operation example, the case where recording is started when another mobile phone whose phone number data is registered in the address book table enters the communicable range of the short-range communication means 103 is described as an example. If the storage capacity of the memory 112 is sufficient, recording may be performed continuously throughout the day. Even in this case, the corresponding conversation part can be reproduced by starting the reproduction of the recording file from the reproduction start point specified based on the start time data as described above. In this case as well, there is a drawback that it takes time until the actual conversation part is reproduced, so it is desirable to take the above-mentioned measures.

  Further, in this operation example 2, when the time zones where two or more acquaintances meet each other overlap each other, the same recording file is associated and the playback start location and playback end location are individually specified. A separate recording file may be generated and stored for each time period. In this case, for example, from the recording files for the overlapping time zones, each part from the playback start location to the playback end location specified by the start time data and the end time data corresponding to each time zone is extracted individually. Save as a file. In this case, when the recorded file is played back as in this operation example 2, it is not necessary to specify a playback start point or a playback end point, start playback from the playback start point, and end the playback when the playback end point is reached. Thus, it is possible to simplify the processing during reproduction.

[Operation example 3]
Next, still another example of the encounter history saving process (hereinafter, this example is referred to as “operation example 3”) will be described.
In this operation example 3, not only the time when the user of the mobile phone 10 meets an acquaintance but also the GPS position information at that time is stored.
FIG. 10 is a flowchart showing the flow of the encounter history saving process in the third operation example.
In the mobile phone 10, as in the case of the operation example 1 described above, an acquaintance's mobile phone provided with a short-range communication means adopting the same Bluetooth short-range wireless communication method as the mobile phone 10 is used as the mobile phone 10. When the communication range of the short-range communication means 103 is entered, a communication link (piconet) is established with the acquaintance's mobile phone (S1 to S3). Then, the control unit 111 of the cellular phone 10 acquires the telephone number data of the acquaintance's cellular phone as in the case of the operation example 1 (S4), and the telephone number data is stored in the address book in the internal memory 112. It is determined whether it is registered in the table (S5). In this determination, when determining that it is registered in the address book table, the control unit 111 acquires date and time data from the clock unit 125 as in the case of the operation example 1 (S6). Further, in the third operation example, the control unit 111 that has been determined to be registered in the address book table also acquires GPS position information from the GPS receiving unit 130 (S61). The acquired date / time data is associated with the telephone number data as start time data, and the acquired GPS position information is also associated with the telephone number data and registered in the encounter history table (S7).

  Thereafter, in the third operation example, the control unit 111 acquires GPS position information from the GPS receiving unit 130 (S63) every time a predetermined time elapses (S63), and associates this with the telephone number data, and the encounter history Register in the table (S64). Similarly to the case of the operation example 1 above, the mobile phone of the acquaintance who is the transmission source of the telephone number data registered in the encounter history table moves out of the communicable range of the short-range communication means 103 of the mobile phone 10. Judgment is made as to whether or not (S8). In the third operation example, the processes of S62 to S64 are repeated until it is determined that the acquaintance's mobile phone has moved out of the communicable range. If it is determined that the acquaintance's mobile phone has moved out of the communicable range, the control unit 111 performs a process of disconnecting the communication link as in the case of the operation example 1 (S9) and the clock unit 125. The date / time data is acquired from (S10). In this operation example 3, GPS position information is also acquired from the GPS receiver 130 (S65). Then, the acquired date / time data is associated with the telephone number data as start time data, and the acquired GPS position information is also associated with the telephone number data and registered in the encounter history table (S11).

An example of the encounter history table obtained in this way is shown in Table 4 below. In order to simplify the explanation, the following Table 4 shows the part of the encounter history table shown in Table 2 in the above operation example 1 that first met Mr. A (from 10:33 to 10:38). Only the time zone is shown. The fixed time is 1 minute.

  As described above, according to the third operation example, the user performs a predetermined key operation on the key operation unit 120 of the mobile phone 10 at the end of the day to execute the list display process. Users can see if they meet and know where they met.

In this operation example 3, the GPS position information is acquired every minute and registered in the encounter history table. However, an acquaintance's mobile phone in which the phone number data is registered in the address book table is near. The GPS position information may be acquired and registered in the encounter history table when entering and leaving the communicable range of the distance communication means 103.
In this operation example 3, GPS position information is acquired only during the period from when it is determined whether the received telephone number data is registered in the address book table in the internal memory 112 until the communication link is disconnected. However, if the storage capacity of the internal memory 112 is sufficient, the GPS position information may be acquired and registered continuously throughout the day. In this case, GPS position information is acquired regularly throughout the day (for example, every minute), and a position history database is created in which each acquired GPS position information is stored in association with data indicating each acquisition time. Then, at the end of the day, when the user performs a predetermined key operation on the key operation unit 120 of the mobile phone 10 and executes the list display process, the acquaintance's mobile phone is connected to the short-range communication of the mobile phone 10. If the GPS position information corresponding to the time determined to have moved out of the communicable range of the means 103 is read out from the position history database and displayed in a list, the same as in the above operation example 3, what time and who met today Users can know and know where they met.

[Operation Example 4]
Next, another example of processing using the encounter history table obtained in the above operation example 1 (hereinafter, this example is referred to as “operation example 4”) will be described.
In this operation example 4, at the end of the day, ranking display processing is performed for ranking display of acquaintances with long encounter times.
FIG. 11 is a flowchart showing the flow of the ranking display process in the fourth operation example.
As in the case of the operation example 1 described above, when the user of the mobile phone 10 performs a predetermined key operation for performing ranking display on the key operation unit 120 after performing the encounter history storage process, the control unit 111. Reads today's encounter history table from the internal memory 112 (S71). Then, the control unit 111 calculates the total encounter time for each person based on the read encounter history table (S72), and extracts information on the top three acquaintances with the long total encounter time from the encounter history table. (S73). Thereafter, the control unit 111 outputs, to the image processing unit 118, a command for causing the extracted three people to display a ranking list as shown in Table 5 below on the liquid crystal display (S74). Receiving this command, the image processing unit 118 performs a drawing process for displaying the ranking list image on the liquid crystal display of the display unit 119 (S75). This allows the user to know who has had a long synthetic encounter time today. Other information besides the information shown in Table 5 below may be displayed in the ranking list.

[Operation Example 5]
Next, another example of processing using the encounter history table obtained in the above operation example 1 (hereinafter, this example is referred to as “operation example 5”) will be described.
In this operation example 5, at the end of the day, an acquaintance meeting at a certain time performs a quiz to ask someone.
FIG. 12 is a flowchart showing the flow of the quiz execution process in the fifth operation example.
As in the case of the operation example 1 described above, when the user of the mobile phone 10 performs a predetermined key operation for performing a quiz on the key operation unit 120 after performing the encounter history saving process, the control unit 111 Then, a quiz application program for performing a quiz is started (S81). Then, the control unit 111 that executes the application program for quiz reads the today's encounter history table from the internal memory 112 (S82), refers to each start time data registered in the encounter history table, and is prepared in advance. A problem to be presented this time is selected from a plurality of problem examples (S83). Here, it is assumed that the same situation as the situation described in the operation example 1 is assumed, and the question “Who met with 12:00 on November 21, 2003?” Is selected. In addition, the control unit 111 that executes the application program for the quiz creates an answer of the selected question (Mr. A and Mr. B) based on the encounter history table, and an acquaintance randomly selected from the address book table The answer of three mistakes is created using the name of (S84). Thereafter, the control unit 111 outputs to the image processing unit 118 a command for causing the liquid crystal display to display a question screen as shown in FIG. 13 on which the selected problem and the four created answers are displayed (S85). . Upon receiving this command, the image processing unit 118 performs drawing processing for displaying the question screen on the liquid crystal display of the display unit 119.

  The user who sees the question screen displayed on the liquid crystal display performs the key operation on the key operation unit 120, and inputs the answer number that he thinks is correct depending on his memory (S86). The control unit 111 determines whether or not the input answer number is correct (S87). If the answer is correct, for example, the control unit 111 performs a process of displaying a correct message “correct answer” on the liquid crystal display (S88). On the other hand, in the case of an incorrect answer, for example, a process of displaying an incorrect answer message “Incorrect answer” and a correct answer content such as “The correct answer is Mr. A and Mr. B” on the liquid crystal display is performed (S89). ).

  In the fifth operation example, the acquaintance who met at a certain time is applied as the content of the quiz, but other quiz content may be used. For example, it may be a quiz that hits the time when you met a certain acquaintance, such as “What time did you meet Mr. B on November 21, 2003?”. Also, for example, a quiz that hits an acquaintance with the longest total encounter time, such as “Who has met the longest on November 21, 2003?” When this quiz is performed, the same process as described in the fourth operation example may be performed to identify the acquaintance who has the longest total encounter time. Also, for example, if you save the encounter history table for one month, “How many times have you met Mr. B this month?”, Such as a quiz that hits the number of times you met an acquaintance within a certain period, It may be a quiz that hits a date with an acquaintance within a certain period, such as “How many days have you met Mr. B this month?”. If the GPS location information is registered in the encounter history table as described in the operation example 3 above, for example, "Who is the person who went to the amusement park together?" It is also possible to give a quiz to hit an acquaintance who was in
