Abstract

<P>PROBLEM TO BE SOLVED: To reduce time from the request to acquisition of current position information while pursuing power-saving properties. <P>SOLUTION: When it is determined that a base station connectable at a current position coincides with information on a base station stored in a storage means, optional information that is stored in the storage means in association with the base station and indicates a location is notified. The optional information to be notified is information stored in the storage means and is not a current position acquired by a position acquisition means. Therefore, there is no such delay as in the case of information acquisition by the position acquisition means, thus reducing notification time to a request source. In addition, no position acquisition means are used, thus saving power, for example, when the position acquisition means acquires current position information based on a GPS signal. <P>COPYRIGHT: (C)2009,JPO&INPIT

  FIG. 2 is a conceptual diagram showing a usage situation of the GPS mobile phone 1. In this figure, for example, six base stations 13 are connected to a mobile phone network 12 as a communication network. Hereinafter, for convenience of explanation, these six base stations 13 will be identified by the letters A to E. Although not shown in this figure, the mobile phone network 12 is also connected to other communication infrastructures such as public telephone lines and the Internet, and various terminals (public phones, mobile phones of other companies or It is possible to communicate with a personal computer or a server.

  The three GPS mobile phones 1 shown in the figure are all the GPS mobile phones 1 described above (see FIG. 1), and here, they are located at different places. That is, it is assumed that the GPS mobile phone 1 on the left side of the drawing is located in “school”, for example, and this “school” is within the communication range 14 of the base stations A, B, and C. In addition, the GPS mobile phone 1 on the lower side of the drawing is assumed to be located in, for example, “school”, and this “school” is assumed to be within the communication range 15 of the base stations C and D. Furthermore, it is assumed that the GPS mobile phone 1 on the upper right side of the drawing is located in “hospital”, for example, and this “hospital” is within the communication range 16 of the base stations F and E.

  Note that the number of base stations 13 (base stations A to F) and places such as schools, cram schools, and hospitals are merely examples for convenience of explanation. The number of base stations may be less than or greater than this, and may be a place other than the above.

  The GPS mobile phone 1 according to the present embodiment will be apparent from the following description. In short, when the current position information is already registered in the base station table 17 and the schedule table 18 described later, the position detection unit 6 (Note that power consumption is large and it takes a considerable amount of time to acquire the current position information). The point is that the time from the inquiry of the position to the notification is shortened, and in addition, the power saving of the GPS mobile phone 1 (and hence the extension of the battery life) is achieved. It is what.

Details will be described below.
FIG. 3 is a conceptual diagram of the base station table 17 and the schedule table 18 held in the storage unit 9 of the GPS mobile phone 1. First, the base station table 17 will be described. The base station table 17 has a plurality of records including a location information field 17a, a base station information field 17b, and a current position information field 17c. Each location includes “location information”, “base station information”, and “current location information”. "Location information" is stored. Here, the “location information” refers to the location information in FIG. 2 (information for location identification arbitrarily set by the user, that is, arbitrary information representing the location), and according to the example of FIG. For example, “school”, “school” or “hospital”. Further, the “base station information” is identification information of the base station 13 in FIG. 2, and according to the example of FIG. 2, “base station A”, “base station B”, “base station C”, “Base station D”, “base station E” or “base station F”. Further, the “current position information” is current position information of each GPS mobile phone 1 in FIG. 2, and is specifically specified by the position detection unit 6 of the GPS mobile phone 1 at each position. Coordinate information on the earth. Incidentally, X1 and Y1 represent current position information of the GPS mobile phone 1 on the left side of FIG. 2, X2 and Y2 represent current position information of the GPS mobile phone 1 on the lower side of FIG. 2, and X3 and Y3 represent The current position information of the GPS mobile phone 1 on the upper right side of FIG. 2 is represented, X represents longitude, and Y represents latitude. In addition to X and Y, altitude information may be stored. In this specification, these current position information (X1, X1 to X3, Y3) are collectively referred to as Xn and Yn. n is 1, 2, 3,.

  Next, the schedule table 18 has a plurality of records including a time field 18a, a day of the week field 18b, and a location information field 18c, and stores “time”, “day of the week”, and “location information” in each record. To do.

  Here, “time” refers to the time zone of the user schedule of the GPS mobile phone 1, and “day of the week” refers to the day of the week on which the schedule is executed, and further, “location” Is the place to execute the schedule. For example, in the illustrated example, a schedule is set for “School” from 08:30 to 16:00 every Monday to Friday, and every Monday, Wednesday and Friday from 17:00 to 21: 00 has a schedule with “Juku” as the location, and every Tuesday from 17:00 to 18:00 has a schedule with “Hospital” as the location. In other words, this user goes to “school” from 8:30 am to 4 pm except Saturday and Sunday, and also goes to “school” from 5 pm to 9 pm after school other than Saturday and Sunday and Tuesday. In addition, on Tuesdays only, we act according to a schedule of going to the hospital for 1 hour from 5pm to 6pm.

  4 and 5 are diagrams showing a simplified flow of a control program for the GPS mobile phone 1, and this control program is periodically executed by the control unit 2 of the GPS mobile phone 1. FIG. When this control program is started, first, a predetermined standby screen is displayed on the display unit 7 (step S11), and it is determined that there is an incoming call (step S12).

  If there is an incoming call, the on-hook operation by the user is determined (step S13). If the on-hook operation is not performed, the process returns to the standby screen display process. If the on-hook operation is performed, the call process is performed (step S13). S14) When the off-hook operation by the user is determined (step S15), and the off-hook operation is determined, the disconnection process (step S16) is performed, and then the process returns to the standby screen display process.

  On the other hand, when there is no incoming call, it is determined that there is an incoming location inquiry from another terminal (step S17). Here, “another terminal” means, for example, a terminal (terminal for inquiring the location of an outside salesman or serviceman) installed at a sales base in the prior art at the beginning, or For example, it is a terminal such as a guardian's cellular phone or a personal computer installed in the guardian's house for inquiring about the owner position of the GPS cellular phone 1 of the present embodiment.

  When there is an incoming location inquiry from another terminal or the like, after executing a “base station acquisition process” (step S18), which will be described later, and a “current position acquisition process” (step S19), which will also be described later, After executing a process of creating a required message based on the acquired information and returning the message to the inquiry source (step S20), a disconnection process (step S16) is performed, and the process returns to the standby screen display process again. The “base station acquisition process” and “current position acquisition process” will be described in detail later.

  If no location inquiry has been received from another terminal or the like, it is next determined whether or not the user has performed an operation of registering base station information (step S21). When the base station information registration operation is performed, the position detecting unit 6 of the GPS mobile phone 1 is set in an operating state, and a position measuring function (using a GPS satellite) by the position detecting unit 6 is activated. Then, the current current position information of the GPS mobile phone 1 is acquired (step S22). Next, a “base station acquisition process” (step S23), which will be described later, is executed, map information is acquired (step S24), and a confirmation screen for the current position is obtained from the acquired information (base station list 19 and map information). It is created (step S25), the confirmation OK operation by the user is determined (step S26), and if the OK operation is not performed, the process returns to step S22 again. On the other hand, if the OK operation is performed, the location information (that is, the user) , Any information representing the location) (for example, character input such as school, cram school, or hospital) is accepted (step S27), and the information (location information, base station information, and current position information) is input to the above-mentioned base After saving in the station table 17 (step S28), the process returns to the standby screen display process again.

  On the other hand, if the base station information registration operation has not been performed, it is next determined whether or not the user has performed a current position transmission operation (step S29), and the current position transmission operation has been performed. In this case, a “base station acquisition process” (step S30) and a “current position acquisition process” (step S31), which will be described later, are executed, a message is created based on the acquired information, and the message is set in advance. After making a call to a predetermined notification destination (for example, a guardian's terminal) (step S32) and performing a disconnection process (step S33), the process returns to the standby screen display process, but the current position is sent. If not, it is determined whether or not it is another operation (step S34). If it is not another operation, the process returns to the standby screen display process. After executing processing (step S35) Flip was, it returns to the idle screen of the display process.

  FIG. 6 is a diagram showing a schematic flow of the “base station acquisition process”. This “base station acquisition process” is the “base station acquisition process” shown in FIGS. 4 and 5 (step S18, step S23, step S30). It corresponds to. In this “base station acquisition process”, first, the nearest base station is searched (step S101) to find all connectable base stations. Then, the radio field strengths of all found base stations are measured (step S102), and it is determined whether the radio field strengths of the respective base stations are equal to or higher than a predetermined value (step S103). Then, a base station having a radio field intensity equal to or higher than a predetermined value is additionally stored in the base station list 19 (step S104), and the process is repeatedly executed until there is no other connectable base station (step S105). The base station list 19 is a temporary storage area of base station information set in the storage unit 9, and more specifically, information on connectable base stations acquired by the position detection unit 6 at the current position. Is temporarily stored and coincident with the base station information registered in the base station table 17 (step S202 in FIG. 7) or when the base station information is registered in the base station table 17 (step S25 in FIG. 5). It is used for step S28).

  FIG. 7 is a diagram showing a schematic flow of the “current position acquisition process”. This “current position acquisition process” corresponds to the “current position acquisition process” (step S19, step 31) in FIGS. . In the “current position acquisition process”, first, the base station table 17 described above is referred to (step S201), and the base station that matches the base station temporarily stored in the base station list 19 is stored in the base station table 17. Is already registered (step S202). If registered, the location information corresponding to the acquired base station information (school, cram school or hospital stored in the base station table 17, that is, any information indicating the location) is acquired (step S203), The current date and time is acquired (step S204), and the above-described schedule table 18 is referred to (step S205). Then, it is determined whether or not the date and time information that matches the schedule table 18 is stored (step S206). If it is stored, the location information corresponding to the date and time information (the school and cram school stored in the schedule table 18) Or hospital) is acquired (step S207), and the location information (school, cram school or hospital stored in the schedule table 18) matches the acquired location information (school, cram school or hospital stored in the base station table 17). It is determined whether or not to perform (step S208).

  If they match, the acquired location information (school, cram school or hospital stored in the schedule table 18) is identified as the current position (step S209), and a notification message based on the current position is created (step S210). If it does not match, the acquisition location information (school, cram school or hospital stored in the base station table 17) is identified as the current location (step S221), and notification based on the current location is performed. A message is created (step S210) and the flow is exited.

  On the other hand, if it is not determined in step S202 that there is matching base station information, then the current date and time is acquired (step S211), and the schedule table 18 is referenced (step S212). Then, it is determined whether or not there is matching date and time information (step S213). If there is matching date and time information, location information corresponding to the date and time information is acquired from the schedule table 18 (step S214). Then, the position detection unit 6 of the GPS mobile phone 1 is put into an operating state, a position measurement function (using a GPS satellite) by the position detection unit 6 is activated, and the current current position information of the GPS mobile phone 1 is acquired. (Step S215). On the other hand, if the matching date and time information is not determined in step S213, step S214 is passed, and the position detection unit 6 of the GPS mobile phone 1 is left in the operating state, and the position measurement by the position detection unit 6 is performed. The function (using a GPS satellite) is activated, and the current current position information of the GPS mobile phone 1 is acquired (step S215).

  Next, the acquired current position information (GPS current position information) is identified as the current position (step S216), a base station information registration confirmation screen is created (step S217), user confirmation OK is determined (step S218), and the user The location information input (for example, character input such as school, cram school or hospital) is accepted (step S219), the input information is registered in the base station table 17 (step S220), and a notification message is created (step S210). And exit the flow.

  FIG. 8 is a diagram illustrating some examples of notification messages transmitted from the GPS mobile phone 1 according to the present embodiment. FIGS. 8A to 8C are diagrams in which acquired base stations are registered in the base station table 17. (D) and (e) are examples in which the acquisition base station is not registered in the base station table 17. More specifically, (a) shows an example in which the location information registered in the schedule table 18 and the location information registered in the base station table 17 match, and (b) shows the location registered in the schedule table 18. This is an example where the information and the location information registered in the base station table 17 do not match. Furthermore, (c) is an example in the case where location information is not registered in the schedule table 18. (D) is an example in the case where the location information is registered in the schedule table 18, and (e) is an example in the case where the location information is not registered in the schedule table 18.

  First, when the base station has already been registered in the base station table 17 and the location information registered in the schedule table 18 matches the location information registered in the base station table 17, (a) For example, a message “I am at school as scheduled” is displayed on the terminal of a parent or the like, for example. Therefore, a guardian or the like can know from the message that the user of the GPS mobile phone 1 is performing as planned.

  On the other hand, when the user performs an action different from the schedule, for example, a message “I am in ●● unlike the current schedule” is displayed as shown in FIG. Here, “unlike the current schedule” is an example of a notification message indicating that the location information does not match the current location information, and “●●” is a location registered in the base station table 17. Information (which is arbitrarily set by the user). Therefore, in this case, you can get a sense of security by taking measures such as confirming by phone, if necessary, because the parents can grasp the location (●●) where they are acting differently than planned. Can do.

  Similarly, if you are taking an irregular action that is not on the schedule, you can display the message “I am currently in ●●” on the parent terminal, as shown in (c). Therefore, a sense of security can be obtained by taking measures such as checking by telephone.

  On the other hand, when communicating with an unregistered base station in the base station table 17, the specific location information (school, cram school, hospital, etc.) cannot be notified, but in such a case, As shown in (d) and (e), current position information based on GPS information (latitude and longitude information based on X and Y coordinates: Xn and Yn) is notified. The current position can be specified by inputting to the system or plotting on a map with latitude and longitude. Again, by taking measures such as confirming by phone if desired You can get a sense of security.

  As described above, according to the GPS mobile phone 1 of the present embodiment, information on the current position can be notified to, for example, a guardian's terminal or the like, so that effective crime prevention measures are taken especially for children such as school children. In addition to being able to obtain the excellent effect of being able to perform the operation, the time from the position inquiry to the notification can be reduced, and in addition, the power saving of the GPS mobile phone 1 (and hence the life of the battery can be extended) can be achieved. A particularly beneficial effect is possible.

  This is because, in the above flow (FIG. 7), when the current position information is already registered in the base station table 17 and the schedule table 18, the power consumption is large, and the time required for acquiring the current position information is large. This is because a required notification message is immediately created based on the registration information of the table and transmitted to the guardian's terminal or the like without starting the position detection unit 6.

  More specifically, the base station information and the current position information are associated and stored in the base station table 17, and the base station 13 that can be connected to the GPS mobile phone 1 at the current position is stored in the base station table 17. If it matches with the station 13, it notifies any information stored in association with the base station table 17 (according to the above example, information such as school, cram school or hospital), and if it does not match, the position detector 6, the current position information is acquired and the current position information is notified, so that each time the current position is not acquired by the position detection unit 6, the current position information can be obtained only with the information of the base station 13. Location information (arbitrary information) can be notified. In addition, since it is only necessary to take out and notify the current position information (arbitrary information) stored in association with the base station table 17, the time is much longer than the time required for acquiring the current position information by the position detection unit 6. Notification can be made in a short time, and furthermore, since the position detection unit 6 is not used, power consumption of the position detection unit 6 can be suppressed, and battery consumption of the GPS mobile phone 1 can be suppressed.

  In addition, when there are a plurality of base stations 13 that can be connected to the GPS mobile phone 1 at the current position, only the information on the base station 13 having a predetermined radio field strength or higher is acquired. The base station 13 to be removed can be excluded, and stable information acquisition of the base station 13 can be performed.

  Further, since the information of the base station 13 is acquired only by the communication terminal device (GPS mobile phone 1) without connecting to the communication network such as the mobile phone network 12, the connection process (negotiation) with the communication network is performed. The information of the base station 13 can be acquired in a shorter time.

  Further, when it is determined that the information of the base station 13 that can be connected at the current position and the base station information stored in the base station table 17 do not match, the position acquired by the position detection unit 6 is registered. Therefore, it is not necessary to perform the registration operation of the base station information one by one, and the labor can be reduced.

  Further, since the acquisition of the current position by the position detection unit 6 is suppressed after the current position information is notified, the power consumption of the position detection unit 6 can be suppressed and power saving can be achieved. Here, “suppression” means the following. In general, the position detection function of the GPS mobile phone 1 (that is, the position detection function using a GPS satellite) is a sub-function that is used irregularly at the request of the user with respect to the call and communication functions that are the main functions of the GPS mobile phone 1. It can be said to be a secondary function (or an auxiliary function), and is fundamentally different from a GPS dedicated terminal (such as a car navigation system) whose position detection function is a main function. Therefore, in the GPS mobile phone 1, the GPS function unit (the position detection unit 6 in the present embodiment) is normally in a power-off state or in a standby state of weak power consumption, and when a required position detection request is made, The GPS function unit (position detection unit 6) is activated by the command from the control unit 2 and transitions to the operating state. After the required position detection processing is performed, the command from the control unit 2 Thus, the original power-off state or the weak power consumption standby state is promptly restored, and the “suppression” refers to this return transition.

  In addition, if the location information registered in the schedule table 18 and the current position information do not match, the current position information and “not match” (for example, “current schedule” in FIGS. 8B and 8D). Unlike "..."), it is possible to confirm whether the user is in the place as planned.

  In addition, when the date and time information and location information are managed in association with each other in the schedule table 18 and the current date and time match with the managed date and time information, the current position information stored in association with the current date and time information is notified. Since the current position is acquired by the position detection unit 6 and notified, the current position information can be quickly and accurately obtained only by the information of the base station 13 without acquiring the current position by the position detection unit 6 every time. In addition, since the position detecting means 6 is not used, power saving can be achieved.

  Further, since the notification is also executed in the form of a response to the inquiry about the current position, it is possible to notify not only the voluntary notification but also the own location according to the request of others.

  In the above embodiment, notification from the GPS mobile phone 1 to, for example, a guardian's terminal is taken as an example. That is, the main functions of the present invention are implemented in the GPS mobile phone 1 that is the notification source. However, the present invention is not limited to this. For example, it can be mounted on a terminal (guardian terminal or the like) that is a notification request source.

  FIG. 9 is a diagram showing a simplified flow of a control program that runs on the terminal that requested notification. Here, if the notification requesting terminal is, for example, a guardian's mobile phone, the GPS function is not essential for this mobile phone. That is, the position detection unit 6 and the GPS antenna 6a may be removed from the configuration of FIG.

  When this control program is started, first, a predetermined standby screen is displayed on the display unit 7 (step S301), and it is determined that there is an incoming call (step S302).

  If there is an incoming call, the on-hook operation by the user is determined (step S303). If the on-hook operation is not performed, the process returns to the standby screen display process. If the on-hook operation is performed, the call process is performed (step S303). S304), an off-hook operation by the user is determined (step S305). When an off-hook operation is determined, a disconnection process (step S306) is performed, and then the process returns to the standby screen display process.

  On the other hand, if there is no incoming call, it is determined whether or not it is an operation for requesting acquisition of the current position for the partner communication terminal device (step S307). Here, the “partner communication terminal device” is at least a cellular communication terminal (typically a mobile phone including a PHS), and has a base station information acquisition function and a more precise current position information acquisition function. (Typically GPS function), and when there is a request for acquisition of base station information or more precise current position information via a communication line, the base station information or current position information is used as a request source. Any terminal may be used as long as it has a function capable of notifying, for example, a mobile phone with a GPS function or a PHS.

  If the current position acquisition request operation for the partner communication terminal device is not determined, it is determined whether the operation is other operation (step S313), and if it is not the other operation, the process returns to the standby screen display process. In the case of other operations, the process corresponding to the operation (step S314) is executed, and then the process returns to the standby screen display process.

  On the other hand, if the current position acquisition request operation for the counterpart communication terminal apparatus is determined, next, the counterpart communication terminal apparatus is instructed to acquire base station information (step S308), and the acquisition base from the counterpart communication terminal is obtained. The station information is received (step S309). Then, with reference to the base station table 17 (FIG. 3A) (step S310), it is determined whether or not a base station that matches the acquired base station information has been registered in the table 17 (step S311). If the matching base station has already been registered in the table 17, the corresponding location information (school, cram school, hospital) in the base station table 17 is identified as the current position (step S312) or matches. If the base station is not already registered in the table 17, the other communication terminal is instructed to acquire more precise current position information (GPS information) (step S315), and the acquired information is received to obtain the current position. After specifying (step S316), in any case, after performing the cutting process (step S306), the process returns to the standby screen display process again.

  As described above, in this embodiment, if the base station information notified from the counterpart communication terminal apparatus has been registered in the base station table 17, the location information (school, cram school) registered in the base station table 17 is registered. , Hospital) can be specified as the current position of the partner communication terminal device. In this case, the partner communication terminal device is not instructed to acquire more accurate current position information (GPS information) (steps S315 and S316). Therefore, it is possible to reduce both the power saving of the counterpart communication terminal device and the time of the current position information notification.

  If the base station acquired from the partner communication terminal is not registered in the base station table 17, the partner communication terminal is instructed to acquire more accurate current position information (GPS information) (step S315). The acquired information is received and the current position of the partner communication terminal is specified (step S316), but the acquired current position information may be registered in the storage unit 9 (the base station table 17). It is possible to grasp the current position of the partner communication terminal more precisely and to grasp the required position even after the line with the partner communication terminal is disconnected.

  In the above embodiment, the application to the GPS mobile phone 1 has been described as an example, but the present invention is not limited to this. In short, any other communication terminal device that is wirelessly connected to a communication network via a base station may be used. For example, wired or wired / wireless mixed via a wireless LAN access point (also referred to as a base station) It may be a communication terminal device such as a personal computer connected to the communication network.
