The suggestion about the communication partner is described. This presentation content predicts in advance the actions that the user should be encouraged in a situation that matches the presentation conditions in the table.

  The presentation condition is information indicating a condition when the advice is presented, and includes a relation tag, an event, and an additional condition. The “relation tag” of the presentation condition is a confirmed relationship tag associated with the communication partner to be advised in the address information 121. The “event” in the presentation condition represents a request for processing that occurs in connection with communication between the terminal and the other terminal. For example, the event “incoming call” indicates that the terminal calls a call. A request for processing when a signal is received, and the event “e-mail creation” indicates a processing request when a user of the own terminal creates an e-mail. The additional condition is information indicating another condition that should be satisfied when the advice is presented. That is, the storage unit 12 including the advice table 126 presents a predetermined condition for the user of the other terminal and the user of the own terminal for each relationship between the user of the own terminal and the user of the other terminal. This corresponds to storage means for storing the contents of actions to be performed in association with each other.

The accumulation control unit 1111 writes the history data indicating the communication history for each type of communication in the communication history information 112 when the communication unit 17 monitors the communication at the own terminal. The estimation unit 1112 refers to the communication history information 122 and the evaluation database 124 and estimates the relationship between the user of the terminal and the communication partner. The notification unit 1113 notifies the user of the own terminal by displaying the relationship estimated by the estimation unit 1112 on the display unit 14. When the operation performed in response to the notification by the notification unit 1113 by the user of the own terminal via the operation unit 13 indicates confirmation for the notification, the specifying unit 1114 displays the current date and time of the confirmation of the address information 121. Write the time. When receiving the communication, the notification unit 1115 determines the notification mode associated with the relationship tag of the communication partner with reference to the notification mode table 125, and performs communication using the voice processing unit 15 according to the notification mode. Notify that you received it. The presentation unit 1116 reads the predetermined condition for the communication partner stored for each relationship between the user of the terminal and the communication partner from the advice table 126, and when there is communication that satisfies the condition, The action content stored in the advice table 126 in association with the condition is displayed on the display unit 14 as “advice”.
The accumulation control unit 1111, the estimation unit 1112, the notification unit 1113, the identification unit 1114, the notification unit 1115, and the presentation unit 1116 are realized by the CPU 111 of the control unit 11.

2. Operation The operation of the present embodiment is roughly divided into a relationship estimation process, a notification process, and an advice presentation process. The contents of these processes will be described below.
2-1. Relationship Estimation Process FIG. 17 is a flowchart showing the contents of the relationship estimation process.
The relationship estimation process is performed by causing the CPU 111 of the control unit 11 to generate an interrupt event when the current time calculated by the timer 114 of the control unit 11 enters a predetermined time zone. When the interrupt event occurs, the CPU 111 of the control unit 11 determines whether there is unconfirmed personal information in the address information 121 (step S101). Specifically, the CPU 111 checks the confirmation date and time of the address information 121 to determine whether or not “−” indicating an empty character string is stored, and when “−” is stored. When it is determined that there is unconfirmed personal information in the address information 121 and “−” is not stored, it is determined that there is no unconfirmed personal information in the address information 121. When it is determined that there is no unconfirmed personal information in the address information 121 (step S101; NO), the CPU 111 ends the process. On the other hand, when it is determined that there is unconfirmed personal information in the address information 121 (step S101; YES), the CPU 111 determines whether a predetermined period has elapsed from the registration date of the unconfirmed personal information. (Step S102). If it is determined that a predetermined period has not elapsed since the registration date (step S102; NO), the CPU 111 ends the process. As described above, when the period elapsed from the registration date is less than the predetermined period, the relationship estimation process is not performed because the history data corresponding to the communication partner is not sufficiently accumulated in the communication history information 122. This is because there are cases. On the other hand, when it is determined that a predetermined period has elapsed from the registration date (step S102; YES), the CPU 111 determines that the reception history information 1221 and the transmission history information 1222 of the communication history information 122 History data including the name of the communication partner indicated by the personal information is extracted (step S103). Then, the CPU 111 evaluates the extracted history data using the evaluation database 124 (step S104).

For example, the extracted history data is evaluated as follows.
First, the CPU 111 identifies which of the time zones Za to Zi corresponds to the date and time when the extracted history data was communicated, and the phrase evaluation data 1241 corresponding to the identified time zone and the communication amount Evaluation data 1242, frequency evaluation data 1243, ratio evaluation data 1244 and section evaluation data 1245 are acquired from the evaluation database 124.
Next, the CPU 111 collates a phrase included in the communication content in the extracted history data with the acquired phrase evaluation data 1241, and specifies an evaluation vector corresponding to each phrase.

  In addition, the CPU 111 totals the communication volumes of the extracted history data, and collates the total value with the acquired communication volume evaluation data 1242. Then, in the traffic evaluation data 1242, the category corresponding to the total value is specified, and the evaluation vector associated with the category is specified.

  In addition, the CPU 111 counts the number of extracted history data, and specifies the reception frequency from the communication partner and the transmission frequency to the communication partner. Then, the CPU 111 collates the specified reception frequency and transmission frequency with the acquired frequency evaluation data 1243, specifies the category to which the above reception frequency and transmission frequency respectively belong in the frequency evaluation data 1243, and sets the category as the category. The associated evaluation vector is specified.

  In addition, the CPU 111 performs a calculation such as dividing the transmission frequency by the reception frequency, and calculates a communication ratio between the user of the terminal and the communication partner. Then, the CPU 111 collates the calculated ratio with the acquired ratio evaluation data 1244, specifies the category to which each of the above ratios belongs in the ratio evaluation data 1244, and sets the evaluation vector associated with the category. Identify.

  Further, the CPU 111 identifies the location of its own terminal when communication is performed from the extracted history data, collates the identified location with the obtained segment evaluation data 1245, and compares the above location in the segment evaluation data 1245. And the evaluation vector associated with the partition is specified.

Next, the CPU 111 sums up a plurality of evaluation vectors specified through the above-described process for each related tag, and calculates a comprehensive evaluation score for each related tag (step S105).
FIG. 18 is a diagram for describing processing for calculating a comprehensive evaluation score for each relation tag. The RAM 113 of the control unit 11 stores a plurality of evaluation vectors specified through the above-described process, and the CPU 111 sums the evaluation points included in all the evaluation vectors for each related tag, A comprehensive evaluation score for each relation tag is calculated. And CPU111 guesses the relationship tag which shows the most probable relationship as a relationship between the user of a self-terminal and a communicating party by specifying the relationship tag with the highest comprehensive evaluation score among each calculated comprehensive evaluation score. (Step S106). That is, the CPU 111 corresponds to an estimation unit that estimates the relationship between the user of the own terminal and the user of the other terminal based on a combination of results obtained by analyzing a plurality of types of communication histories accumulated by the accumulation unit. .

  For example, in the example shown in FIG. 18, since the evaluation vector including six comprehensive evaluation points is (8, 15, 17, 11, 13, 14), the third “17” is the highest comprehensive evaluation point. It is. Here, since the third relationship tag is “friend”, in this case, “friend” is estimated as a relationship tag indicating the most probable relationship between the user of the terminal and the communication partner.

  Thereafter, the CPU 111 writes the identified relation tag in the address information 121 (step S107). In addition, the CPU 111 displays the relationship tag on the display unit 14 together with the name of the communication partner as an estimation result about the relationship between the user of the terminal and the communication partner, and confirms whether the estimation result is correct. A message prompting to do so is displayed on the display unit 14 (step S108).

  When the user of the own terminal performs an operation via the operation unit 13 in response to this message, the CPU 111 receives an operation signal corresponding to this operation from the operation unit 13 (step S109). It is determined whether or not the relation tag is correct, that is, whether or not it indicates confirmation of the estimation result (step S110). When the operation signal indicates confirmation of the estimation result (step S110; YES), the CPU 111 calculates the confirmation date and time corresponding to the communication partner in the address information 121 as the timer 114. The current time is written (step S111). Thereby, the relationship between the user of the terminal and the communication partner is specified. If the operation signal does not indicate confirmation of the estimation result (step S110; NO), the CPU 111 ends the process without rewriting the address information 121.

By performing the above relationship estimation process, for address information that has passed a certain period since registration, a relationship tag is estimated based on the communication history, and the user is prompted to confirm. Then, the relationship tag confirmed by the user is specified as indicating the relationship between the user and the user of the other terminal. That is, the CPU 111 that performs the relationship estimation process specifies the relationship between the user of the terminal and the user of the other terminal based on the combination of the results of analyzing the plurality of types of communication history accumulated by the accumulation unit. It corresponds to the specific means.
This saves the user the trouble of classifying personal information for each communication partner.

2-2. Notification Process FIG. 19 is a flowchart showing the content of the notification process. The CPU 111 of the control unit 11 monitors the communication unit 17 to determine whether communication has been received from another terminal, that is, whether an e-mail has been received or whether an incoming call has been received (step S201). . While not receiving communication from another terminal (step S201; NO), the CPU 111 continues the above determination. On the other hand, when communication from another terminal is received (step S201; YES), the CPU 111 identifies the communication partner that has transmitted the communication (step S202), and stores the relationship tag of the identified communication partner in the address of the storage unit 12. It identifies with reference to the information 121 (step S203). And CPU111 extracts the alerting | reporting mode matched with the specified relationship tag from the alerting | reporting mode table 125 (step S204), and alert | reports that the communication of the user of the own terminal was received by the extracted alerting | reporting mode ( Step S205).

  By performing the above notification process, reception notification is performed according to the relation tag indicated by the address information 121, so that the user of the terminal can cope with communication performed in the past with the communication partner. It is recognized that the communication from the communication partner has been received.

2-3. Advice Presentation Process FIG. 20 is a flowchart showing the contents of the advice presentation process. The CPU 111 of the control unit 11 refers to the advice table 126 and determines whether or not an event corresponding to the related tag in the table has occurred for the communication partner belonging to the related tag of the presentation condition (step S301). While it is determined that no event has occurred (step S301; NO), the CPU 111 continues this determination. On the other hand, when it is determined that an event has occurred (step S301; YES), the CPU 111 refers to the advice table 126 and determines whether or not an additional condition corresponding to the generated event is satisfied (step S302). ). When it is determined that the additional condition is not satisfied (step S302; NO), the CPU 111 returns the process to step S301. On the other hand, when it is determined that the additional condition is satisfied (step S302; YES), advice is presented along the presentation content described in the advice table 126 corresponding to the satisfied additional condition (step S303).

Here, for example, it is assumed that the address information 121 shown in FIG. 3 and the advice table 126 shown in FIG. 15 are stored in the storage unit 12. When there is an incoming call from another terminal owned by “* da × Buro”, the CPU 111 refers to the address information 121 and checks the confirmation date and time corresponding to this communication partner. Since this confirmation date and time is “-”, the relation tag corresponding to this communication partner has not been confirmed. In this case, the CPU 111 determines that no event has occurred.
On the other hand, if a confirmation operation is received from the user of the own terminal for the “colleague”, which is a result of the estimation of the relation tag corresponding to the communication partner, before the incoming call, The date and time when this confirmation operation was performed is written in the confirmation date and time corresponding to the other party. In this case, the related tag “colleague” corresponding to this communication partner with an incoming call has been confirmed. Therefore, the CPU 111 determines that an event has occurred and determines whether or not the additional condition associated with this event is satisfied. As shown in FIG. 15, in this additional condition, “there is a business trip scheduled to go with the communication partner within 3 days” is described. Therefore, the CPU 111 refers to the schedule information 123 and searches for a schedule describing this communication partner as the partner. Here, if a schedule related to this communication partner “* da × Buro” is stored in the schedule information 123 two days later, the above-mentioned additional conditions are satisfied, so the CPU 111 satisfies the additional conditions in step S302. The character string “Is it a meeting about the schedule? Hurry up!” Is displayed on the display screen 141 as advice.

  Similarly, when the user of the own terminal starts to create an e-mail to be transmitted to the communication partner whose relationship tag is “lover”, the e-mail sent by the user in the last two weeks is shown in FIG. When the number of “heart-shaped pictograms” shown is less than the threshold set in the presentation condition, the CPU 111 displays a character string “Recent emails have few heart-shaped pictograms. Send me!” It is displayed on the display screen 141 as advice. In this case, since the content of the received electronic mail is analyzed as the additional condition, the CPU 111 may refer to the communication history information 122 of the storage unit 12. In this configuration, the own terminal presents advice regarding the content to be communicated next based on the communication content transmitted from the communication history included in the communication history information 122 to the communication partner.

  In addition, an email is received from a communication partner whose relationship tag is “family”, and an anniversary date for the communication partner is registered in the schedule information 123 within one week from that date. When any of a plurality of product names stored in advance in the storage unit 12 is found, the CPU 111 presents the URL of the shop site that trades the product indicated by the “product name” and the product. Following the name, a character string “What should I give?” Is displayed on the display screen 141 as advice. Even in this case, the CPU 111 may refer to the communication history information 122 in the storage unit 12. In this configuration, the own terminal estimates the status of the communication partner from the communication history included in the communication history information 122 and presents advice according to the status.

  Also, when one month has passed since the last e-mail was sent to the communication partner whose relationship tag is “friend”, the CPU 111 reads “Did you forget? Forgot it? The column is displayed on the display screen 141 as advice. That is, in this case, the display unit 14 determines that the condition stored in the storage unit in association with the certain relationship is satisfied for the user of the other terminal belonging to the certain relationship specified by the specifying unit. This is an example of a presentation unit that presents the content of the action stored in association with the condition by the storage unit to the user of the own terminal.

  By performing the above advice presentation process, advice according to the state of each of the plurality of communication partners is presented, so that the user of the own terminal can accurately perform communication and action for each communication partner.

3. Modification The above is the description of the embodiment, but the contents of this embodiment can be modified as follows. Further, the following modifications may be combined.
(1) In the above-described embodiment, the position measurement unit 16 measures the position of the terminal using the GPS method, but may measure the position of the terminal using a method other than the GPS method. For example, the position measurement unit 16 may acquire information specifying the wirelessly connected base station 2 from the communication unit 17 and specify the position of the own terminal based on this information. In this case, information for specifying the base station 2 and information indicating the location of the base station 2 (coordinates represented by latitude and longitude, etc.) are stored in advance in the storage unit 12 and the ROM 112, and the CPU 111 stores the storage unit 12. Etc., it may be specified that the terminal is in a certain area based on the base station 2.

  In the above-described embodiment, the position of the terminal measured by the position measurement unit 16 is represented by coordinates including latitude and longitude, but includes height in addition to latitude and longitude. It may be represented by a three-dimensional coordinate. Thereby, for example, communication when the terminal is on a higher floor of a building and communication when the terminal is on a lower floor are distinguished in the communication history information 122.

(2) In the above embodiment, for example, a certain type such as a value obtained by dividing the number of e-mails sent from the own terminal to the other terminal by the number of e-mails sent from the other terminal to the own terminal. The value obtained by dividing the number of transmissions related to the communication by the number of receptions related to the same type of communication as the communication was calculated as the communication ratio. In the calculation of the communication ratio, the type of the number to be divided may be different from the number to be divided, such as calculating the communication ratio by dividing by the number of e-mails sent from the terminal to the own terminal.

(3) In the above-described embodiment, the CPU 111 sums up the evaluation points related to various data included in the evaluation database 124 when calculating the comprehensive evaluation point for each related tag. You may calculate a comprehensive evaluation score with another variable function. For example, among the evaluation points evaluated for a certain relation tag, the evaluation point in the phrase evaluation data 1241 is v1, the evaluation point in the traffic evaluation data 1242 is v2, the evaluation point in the frequency evaluation data 1243 is v3, and the ratio evaluation data 1244 Assume that the evaluation point in is v4 and the evaluation point in the block evaluation data 1245 is v5. In the program executed by the CPU 111, a multivariable function f (v1, v2, v3, v4, v5) having the evaluation points v1, v2, v3, v4, and v5 as variables is described in advance. A comprehensive evaluation point v is calculated based on this multivariable function. The multivariable function f (v1, v2, v3, v4, v5) may be obtained by adding, subtracting, multiplying and dividing each variable, for example, v1 × v2 + v3 × log (v4) ÷ v5. It may contain functions.
Moreover, it may be shown that the lower the evaluation score, the more likely the corresponding relation tag is.
In the above-described embodiment, there are six relation tags. However, the number of relation tags is not limited to six, and may be two or more.

(4) In the above-described embodiment, the time zone distinguishes weekdays and holidays, and each is divided into a plurality of time zones. However, weekdays may be finely divided by day of the week, and the number indicating the day is A day that satisfies a predetermined condition, such as a day that is a multiple of 5, may be distinguished from other days. Holidays may be divided into different time zones on Saturdays, Sundays and public holidays. The time zone classification may be different for each type of data included in the evaluation database 124 such as the phrase evaluation data 1241 and the traffic evaluation data 1242.

(5) In the above-described embodiment, the relationship estimation process is performed when the current time enters a predetermined time zone, but may be performed when a call is made or a call is received. In this case, the relationship inference process may be performed for every outgoing call or incoming call, or the number of calls or incoming calls may be counted and the relationship inference process may be performed every predetermined number of times. Further, the relationship inference process may be performed at a timing when new history data is added to the communication history information 122 stored in the storage unit 12 after communication is performed.

  In the above-described relationship estimation process, the CPU 111 has determined whether a predetermined period has elapsed since the registration date of unconfirmed personal information registered in the address information 121. This determination is performed. It does not have to be. In this case, the history data corresponding to the communication partner may not be sufficiently accumulated in the communication history information 122. However, when it is not possible to specify the relationship tag with the highest overall evaluation score, the relationship estimation process is terminated. do it.

(6) In the above-described embodiment, when the number of “heart-shaped pictograms” written in the email sent by the user in the last two weeks is less than the threshold set in the presentation condition, Although the advice which urges the user of the terminal to enter a heart-shaped pictogram in the e-mail is presented, other advice may be given. For example, if the same “heart-shaped pictogram” is described in the e-mail every time, the communication partner may get bored. Therefore, when the same “heart-shaped pictograms” equal to or greater than the threshold are entered in the e-mail sent by the user during a certain period, the CPU 111 determines that the “heart-shaped pictograms” Advice that encourages the user to replace the pictograph may be presented. Here, “other pictograms” that prompt the user to replace the above “heart-shaped pictograms” may be determined using the phrase evaluation data 1241. Specifically, a “heart-shaped pictogram” in which the user has entered a number greater than or equal to the threshold value may be searched from the phrase evaluation data 1241, and a pictograph belonging to the same group may be determined as “another pictograph”. When there are a plurality of pictograms belonging to the same group, the pictogram with the highest evaluation score of the relation tag associated with the communication partner may be determined as “another pictogram”. If there are multiple pictograms with the same evaluation score, generate pseudo-random numbers, etc., assign random numbers to each of the pictograms, compare the assigned random numbers, and decide one of them as `` other pictograms '' May be.

  Note that the phrase may belong to each of a plurality of groups. In this case, information indicating a plurality of groups is described as a group of the phrase evaluation data 1241. In addition, the group to which the phrase belongs may be divided into hierarchies. For example, when a group to which a word belongs is called a small group and a group to which the small group belongs is called a large group, each word in the word evaluation data 1241 includes a small group to which the word belongs and a large group to which the group belongs. It is only necessary to be associated with each group. In this case, for example, when the above-mentioned “heart-shaped pictogram” belongs to the “favorite expression” group, which is a small group, and the “favorite expression” group belongs to the “pictogram” group, "Is associated with each of the" expression of favor "group and the" pictogram "group.

(7) In the above-described embodiment, in the communication history information 122, when communication performed between the own terminal and another terminal is a call, only the history when the call is established is written as history data. However, the history when the call is not established may also be written as history data. In short, the CPU 111 may write the history data in the communication history information 122 of the storage unit 12 at the “incoming call” stage corresponding to the communication even if the call is not reached.
For example, the CPU 111 may add history data to the reception history information 1221 of the communication history information 122 when the user does not perform an operation of receiving a call despite an incoming call. In this case, the name of the communication partner that received the call is described in the name of the history data, and “call” is described in the type. The date / location of the history data describes the date / location of the incoming call, the empty data for the content, and “0” for the traffic. That is, this history data represents “missed call”. Here, the evaluation database 124 includes “missed call evaluation data” in which an evaluation vector in which an evaluation score is determined for each related tag according to the number of missed calls is described. Then, when performing the relationship estimation process, the CPU 111 counts the number of missed calls and specifies an evaluation vector corresponding to the counted number of missed calls from the “missed call evaluation data”. Thereby, the CPU 111 calculates an overall evaluation score for each related tag using the evaluation vector corresponding to the number of missed calls in addition to the plurality of evaluation vectors specified in the above-described embodiment, What is necessary is just to guess the relationship tag which shows the most probable relationship as a relationship with a communicating party. For example, since the time zone Zb shown in FIG. 7 is from 7 o'clock to 19 o'clock on weekdays, it is considered to correspond to the time zone during work. When the number of missed calls is large in this time zone Zb, the human relationship with the communication partner is not related to work and is often private. Accordingly, the higher the number of missed calls in the time zone Zb, the higher the evaluation score of the relation tag of “friend” or “lover”. In addition, when the user of the own terminal keeps away from the communication partner, the number of missed calls increases at any time zone. For example, in such a case, a relation tag such as “person who does not want to speak” may be provided as a relation tag corresponding to the communication partner. For a communication partner who has been confirmed as belonging to “person who does not want to talk”, for example, the CPU 111 may provide advice to set reception rejection or actually set reception rejection. Good.

(8) In the above-described embodiment, the CPU 111 has estimated one relationship tag indicating the most probable relationship as the relationship between the user of the terminal and the communication partner in the relationship estimation process. In addition, a relationship tag indicating the second and third most likely relationship may be estimated and written in the address information 121. That is, a plurality of relation tags may be determined in descending order of the total evaluation score, and the human relation between the user of the terminal and the communication partner may be specified by a combination thereof. In this case, for example, in the notification mode table 125, in addition to the confirmed relation tag, “second relation tag” which is a relation tag estimated as the second most likely relation is described. And even if the confirmed relation tag is the same in the notification mode table 125, when this second relationship tag is different, different notification modes are associated with each other. Depending on the combination of the relationship tag and the second relationship tag, the user of the terminal is notified that the communication has been received in different notification modes.

(9) In the above-described embodiment, only the confirmed relation tag as the presentation condition is described in the advice table 126, but an unconfirmed relation tag may be described. In this case, even if the relation tag corresponding to the communication partner is unconfirmed, the CPU 111 determines that an event has occurred. In this case, if there is an unconfirmed relation tag included in the presentation conditions of the advice table 126, the event matches, and the additional conditions are satisfied, the CPU 111 sets the corresponding presentation content. Give advice along.

(10) In the above-described embodiment, the evaluation database 124 includes the phrase evaluation data 1241, the communication amount evaluation data 1242, the frequency evaluation data 1243, the ratio evaluation data 1244, and the section evaluation data 1245. It is not necessary to include at least two types of evaluation data.
In the above-described embodiment, the address information 121, the communication history information 122, the schedule information 123, the evaluation database 124, the notification mode table 125, and the advice table 126 are stored in the storage unit 12. It may be described in advance in the ROM 112 of the control unit 11 or a program read from the ROM 112 by the CPU 111. In addition, the information may be acquired from the outside by the CPU 111 via the communication unit 17 provided in the communication terminal 1, various connection interfaces (not shown), or the like.

(11) In the above-described embodiment, the information indicating the communication history is stored in the storage unit 12 of the communication terminal 1, but may be stored in an external storage device connected to the communication line 3. That is, the external storage device is connected to a communication line that relays a plurality of types of communication performed between two communication terminals, and stores a history for each type of communication for each combination of the two communication terminals. Function as. In this case, the CPU 111 of the terminal itself may acquire the communication history stored in the external storage device via the communication line 3 and the base station 2 and perform the relationship estimation process.

  In this case, the relationship inference process may be performed by an external control device connected to the communication line 3. In this case, if the address information 121 includes unconfirmed personal information, the CPU 111 of the terminal itself externally controls a request for inferring a relation tag corresponding to the personal information via the base station 2 and the communication line 3. Send to device. Upon receiving this request, the external control device performs a relationship estimation process based on the communication history stored in the external storage device, estimates the relationship tag corresponding to the personal information included in this request, and responds to the request as a response to this request. What is necessary is just to send an estimation result to CPU111. That is, this external control device is connected to a communication line, and based on a combination of results obtained by analyzing a plurality of types of communication history accumulated by the storage device, users of two communication terminals that have performed communication Information indicating the relationship between the user of the communication terminal and the user of the other communication terminal from any one of the two communication terminals that performed communication, and a specifying means for specifying the relationship between the two communication terminals When the request to be received is received, the relationship is specified, and the device functions as a specifying device having transmission means for transmitting information indicating the specified relationship to one of the communication terminals. The communication system 9 according to the present invention can be considered as a communication system including the external storage device and the external control device.

(12) In the above-described embodiment, the type of communication is identified by the communication protocol used for the communication. However, the communication is “voice communication” which is communication using voice, and voice is not used. You may classify | categorize into two types of "non-voice communication (or character communication)" which is communication. In this case, the CPU 111 performs voice recognition processing for voice communication and rewrites the communication history information 122 without performing voice recognition processing for non-voice communication. In this case, the above-described “e-mail” and “short message service” are classified as the same type of communication.

(13) In the above-described embodiment, the communication system 9 includes the plurality of communication terminals 1, the plurality of base stations 2, and the communication line 3, but instead of the plurality of base stations 2 and the communication line 3, these In addition, a wireless or wired LAN (Local Area Network) may be provided. In this case, the plurality of communication terminals 1 are connected to a wireless LAN corresponding to the communication line 3 via a wireless LAN access point corresponding to the base station 2 or are connected to the communication line 3 via a wired router corresponding to the base station 2. Or a wired LAN corresponding to In addition, when the position measurement unit 16 of the communication terminal 1 acquires information for specifying the base station and specifies the position of the own terminal as in the above-described modification 1, the position measurement unit 16 is connected to the own terminal. What is necessary is just to acquire the MAC address etc. of the communication apparatus which is a communication apparatus which relays communication between the own terminal and the communication line 3, and specifies the position of the own terminal based on this.
The communication terminal 1 may be any of various terminals having a communication function, such as a mobile phone, a PDA (Personal Digital Assistant) terminal, and a personal computer terminal.
