Disseminating information.
Japanese Patent Laid-Open No. 2002-216021

  However, in the conventional system, what kind of content information is transmitted corresponding to the position information cannot be confirmed in advance on the mobile station side. Therefore, even when there is no change in the distributed content information, it is necessary to periodically transmit position information, and it is easy to lead to unnecessary content information transmission, which is inefficient.

  Accordingly, an object of the present invention is to provide a distribution server, a mobile station, a distribution system, and a distribution method that enable efficient transmission and reception of content information.

In order to solve the above problems, a mobile station according to the present invention is a mobile station capable of receiving content information distributed from a distribution server that can set a transmission cycle of position information of the mobile station, and has a predetermined positioning cycle. Positioning means for positioning the position information at the position, the position information transmission server to the transmission server is set based on the setting instruction information set on the distribution server side, and the position information is transmitted to the distribution server at the set transmission period Receiving means for receiving content information corresponding to the position information from the distribution server, receiving means for receiving content position information for specifying a location provided by the content information, and a plurality of contents received from the distribution server Information storage means for storing information in association with the content position information, and information stored in the information storage means at an output cycle shorter than the positioning cycle. An output control means for outputting Ntsu information includes an operation accepting unit that accepts an input operation of a user for outputting the content information, and a timer means for counting an elapsed time of the output period, the. In this mobile station, when the output control means determines that the output cycle has elapsed based on the time counted by the timer means, the content is stored from the mobile station in the content information stored in the information storage means. When the content information corresponding to the content position information closest to the latest position information transmitted to the server is output, the timer means is reset, and when the input operation is accepted by the operation accepting means, the information accumulating means The content information corresponding to the content location information closest to the latest location information transmitted from the mobile station to the distribution server is output, and the timer means is reset.

According to this mobile station, the transmission period of the position information is to be managed by the distribution server. The distribution server is responsible for transmitting the content information corresponding to the location information. When the transmission cycle of the location information can be managed on the distribution server side, the content information transmitted to the mobile station and the transmission cycle are linked on the distribution server side. and it is managed, efficient reception of the content information can be ing useless transmission of location information of the mobile station is reduced. Further, in this mobile station, content information is output with an output cycle shorter than the positioning cycle, so that the number of times of notification of content information can be increased as compared with outputting with a cycle longer than the positioning cycle. In addition to the elapse of the output cycle, the mobile station outputs content information corresponding to the content position information closest to the latest position information in accordance with the user's input operation, thereby improving user convenience. In addition, since the timer means is reset when the content information is output by the user's input operation, the output of the same content information due to the elapse of the output cycle is prevented immediately after the content information is output.

Furthermore, it is preferable that the mobile station further includes a transmission cycle changing unit that changes a transmission cycle based on the setting of the distribution server, and a positioning cycle changing unit that changes the positioning cycle. In this case, it is possible to change the setting of the transmission cycle and the setting of the positioning cycle, and it is possible to efficiently receive content information. More preferably, the positioning period changing means changes the setting of the positioning period in accordance with the transmission period set and changed by the transmission period changing means. In this case, it is possible to change the setting to the positioning cycle in accordance with the transmission cycle whose setting has been changed, and it is possible to receive content information more efficiently.

Further, the mobile station further includes a remaining battery level detecting unit that detects the remaining battery level, and the transmission cycle changing unit changes the transmission cycle according to the remaining level detected by the remaining battery level detecting unit. The positioning cycle changing means preferably changes the positioning cycle so as to be equal to the transmission cycle set or changed by the transmission cycle changing unit or shorter than the transmission cycle. The transmission cycle is changed according to the remaining battery level, and the positioning cycle is changed to be equal to or shorter than the transmission cycle after the setting change. It is valid.

Further, in the above mobile station, it is preferable that at least one of the transmission cycle changing means and the positioning cycle changing means is set and changed so that the positioning cycle is equal to the transmission cycle, or the positioning cycle is shorter than the transmission cycle. . Since the setting cycle is changed so that the positioning cycle is equal to the transmission cycle or the positioning cycle is shorter than the transmission cycle, the same position information based on the positioning result in one positioning cycle is not transmitted multiple times. . Accordingly, it is possible to reduce the reception of the same content information multiple times and to efficiently receive the content information.

Further, the mobile station further includes terminal open / close detection means for detecting whether the mobile station is in an open state where content information is output or a closed state where output of content information is stopped. The transmission cycle changing unit or the positioning cycle changing unit is preferably configured to change the positioning cycle or the transmission cycle according to the state detected by the terminal opening / closing detection unit. In the state detected by the terminal open / close detection means, for example, in the closed state, the output of the content information is stopped, and therefore the setting can be changed so that the positioning cycle is longer than that in the open state. And by changing the setting to increase the transmission cycle in accordance with the setting change of the positioning cycle, efficient positioning can be performed while reducing the number of transmissions per predetermined time and suppressing battery consumption.

Further, in the above mobile station, it is preferable that the output control means controls whether or not the content information can be output according to the open / closed state detected by the terminal open / close detection means.

In addition, the mobile station includes a positioning history storage unit that associates time information and position information of past positioning and stores them as a positioning history, and a plurality of recent positioning records stored in the positioning history storage unit. A moving speed estimating means for estimating the moving speed of the mobile station from the positioning history, wherein the transmission cycle changing means or the positioning cycle changing means is a positioning cycle or a transmission cycle according to the moving speed estimated by the moving speed estimating means. It is preferable to change the setting. Depending on the movement speed estimated by the movement speed estimation means, for example, the current movement speed estimated from a plurality of recent positioning histories is compared with the movement speed estimated in the past, and the current movement speed is faster. For example, since the positioning position changes quickly, the setting is changed to shorten the positioning cycle. In addition, by performing a setting change that shortens the transmission period in accordance with the setting change of the positioning period, it becomes possible to perform highly accurate positioning and efficient content information reception.

Further, in the above mobile station , the output control means extracts the content information corresponding to the content position information in the order close to the latest position information from among the plurality of content information stored in the information storage means, and the extracted order It is preferable to output the content information.

A distribution system according to the present invention includes the above-described mobile station, and a distribution server having a transmission cycle setting unit that sets a transmission cycle of position information periodically transmitted from the mobile station. Yes.

In this distribution system, content information to be transmitted to a mobile station and a transmission cycle can be managed in conjunction with the distribution server side, and transmission of useless position information in the mobile station is reduced, and content information is efficiently transmitted. Transmission or reception of content information at the mobile station becomes possible.

Furthermore, in the above distribution system, it is preferable that the transmission cycle setting means of the distribution server sets the transmission cycle so as to be longer than the positioning cycle. Positioning at the mobile station is performed periodically. By adopting the above configuration, it is possible to prevent the same position information as a result of being transmitted to the distribution server from being transmitted many times, and to reduce the same content information from being transmitted to the mobile station many times. Is done.

Furthermore, in the above distribution system, the distribution server further includes distribution control means for transmitting content information corresponding to the distribution area when the positioning position of the mobile station specified from the position information is within a predetermined distribution area, The transmission cycle setting means of the distribution server sets the transmission cycle to be the reference time interval when the distance from the positioning position of the mobile station to the distribution area is less than a predetermined threshold, and distributes from the positioning position of the mobile station. When the distance to the area is equal to or greater than a predetermined threshold, it is preferable to set the transmission cycle so that the time interval is longer than the reference time interval. When the distance from the positioning position of the mobile station to the distribution area is equal to or greater than a predetermined threshold, it can be determined that the distance from the distribution area is far compared to the case where the distance is less than the predetermined threshold. I have time to spare. Therefore, by making the transmission cycle longer than the reference time interval when the threshold is equal to or greater than the predetermined threshold, transmission of useless position information from the mobile station is reduced, and efficient transmission of content information becomes possible.

In addition, a distribution method according to the present invention includes a mobile station that measures position information at a predetermined positioning cycle, and a distribution server that distributes content information corresponding to the position information transmitted from the mobile station to the mobile station. A distribution method executed in the system, in which a transmission server sets a transmission cycle of position information periodically transmitted from a mobile station, and mobile station position information at a predetermined positioning cycle.

In addition, an information receiving step for receiving content location information for specifying a location where information is provided by the content information, and information storage stored in the mobile station in association with the plurality of content information received from the distribution server in association with the content location information An output control step in which the mobile station outputs the content information stored in the information accumulation step with an output cycle shorter than the positioning cycle, and an operation reception step in which the mobile station accepts a user input operation for outputting the content information And a timer timing step in which the mobile station times the elapsed time of the output cycle. In this distribution method, in the output control step, when it is determined that the output cycle has elapsed based on the time measured in the timer timing step, the most recent position information transmitted from the mobile station to the distribution server is the most. Outputs the content information corresponding to the near content position information, resets the time count in the timer timing step, and if the input operation is accepted in the operation acceptance step, the latest information sent from the mobile station to the distribution server The content information corresponding to the content location information closest to the location information is output, and the time measurement at the timer timing step is reset.

In this distribution method, content information to be transmitted to a mobile station and a transmission cycle can be managed in conjunction with the distribution server side, and transmission of useless location information in the mobile station is reduced, and content information is efficiently transmitted. Transmission or reception of content information at the mobile station becomes possible. In addition, since the content information is output with an output cycle shorter than the positioning cycle, the number of notifications of the content information can be increased as compared with outputting with a cycle longer than the positioning cycle. Then, in addition to the elapse of the output cycle, content information corresponding to the content position information closest to the latest position information is output according to the user's input operation, so that the convenience of the user can be improved, When the content information is output by the user's input operation, it is reset in the timer timing step, so that the output of the same content information due to the elapse of the output cycle is prevented immediately after the content information is output.

In the GPS positioning, the latitude and longitude are calculated based on data from at least three or more GPS satellites, and the position information of the mobile terminal 2 is obtained. Instead of GPS positioning, positioning by single station positioning, a combination of GPS positioning and single station positioning, or multiple station positioning may be executed.

The positioning cycle T2 is set and changed so as to be shorter than the cycle T1. For example, the transmission cycle changing means 2g changes the transmission cycle T1 so that the time interval becomes longer than the transmission cycle T1 at the completion of charging when the remaining amount of the battery 29a becomes smaller than a predetermined threshold.

  The battery remaining amount detecting means 2h detects the remaining amount of the battery 29a of the power supply unit 29. The operation accepting unit 2j accepts an input operation by the user for displaying content information on the screen.

  FIG. 3 is a diagram illustrating a hardware configuration of the distribution server 3. The distribution server 3 is a device that transmits content information corresponding to the position of the mobile terminal 2, and physically includes a CPU 31, a ROM 32, a RAM 33, an input device 34, an output device 35, a communication module 36 that is a data transmission / reception device, and An auxiliary storage device 37 is provided.

  Further, as shown in FIG. 1, the distribution server 3 includes a content information storage unit 3a, a transmission cycle setting unit 3b, a distribution control unit 3c, and the like as functional configurations.

And reading and writing data in the RAM 33.

  Information for specifying each of the plurality of distribution areas is stored in the content information storage unit 3a. The distribution area may be, for example, an area that includes a specific address or landmark, or an area that includes a specific commercial facility such as a shopping center. The distribution area is arbitrarily determined by the communication carrier or the like, and the boundary information for specifying the distribution area is arbitrarily set by the communication carrier or the like.

  Furthermore, content information corresponding to each of a plurality of distribution areas is stored in the content information storage unit 3a. The content information includes a wide range of information such as restaurants, retail stores, amusement facilities, parks or public facilities that operate in the distribution area. Further, the content information storage means 3a stores content position information for specifying the location where the information is provided by the content information corresponding to the content information. The content location information is, for example, information for specifying the location of a restaurant or retail store, a specific park, a public facility, or the like as a content information provider.

  The transmission cycle setting unit 3 b transmits setting instruction information for the transmission cycle T <b> 1 to the mobile terminal 2 in order to set the transmission cycle T <b> 1 of position information periodically transmitted from the mobile terminal 2. In the transmission cycle setting means 3b, information related to the positioning cycle T2 is received from the portable terminal 2 in addition to the position information. Then, the transmission cycle setting unit 3b transmits the setting instruction information of the transmission cycle T1 to the mobile terminal 2 so that the transmission cycle T1 is longer than the positioning cycle T2. As a result, the consumption of the battery 29a of the mobile terminal 2 can be suppressed as compared with the case where the position information is transmitted every time the positioning is performed.

  In particular, when the distance D from the positioning position P (see FIG. 8) of the mobile terminal 2 to the distribution area Ar is less than a predetermined threshold Th, the transmission cycle setting unit 3b sets the transmission cycle T1 as the reference time interval. When the distance D from the positioning position P of the mobile terminal 2 to the distribution area Ar is equal to or greater than a predetermined threshold Th, the transmission cycle T is set to be a time interval longer than the reference time interval. The setting instruction information is transmitted to the mobile terminal 2.

  When the distribution control means 3c acquires the position information from the portable terminal 2, whether the latitude and longitude specified from the position information, that is, the positioning position, is within any one of the plurality of distribution areas. Determine. And when determining that it exists in one of the delivery areas, the delivery area including the positioning position is identified as the located area, the content information corresponding to the located area, and the content location information corresponding to the content information Are extracted from the content information storage means 3a and distributed (transmitted) to the portable terminal 2.

  Next, a distribution method for distributing content information to the mobile terminal 2 using the distribution system 1 will be described with reference to FIGS. 4 and 5. FIG. 4 is a sequence chart mainly showing the flow of information transmitted and received between the mobile terminal 2 and the distribution server 3. FIG. 5 is a flowchart showing an operation procedure relating to positioning and position information transmission on the mobile terminal side and content information transmission on the distribution server side.

  In the mobile terminal 2, a positioning cycle T2 is set in advance. The transmission cycle T1 is set to be longer than the positioning cycle T2 based on a setting instruction from the distribution server 3.

  The positioning means 2b monitors the T2 timer 2m (step S11), and the position notification means 2e monitors the T1 timer 2k (step S14). When the count value of the T2 timer 2m reaches the positioning cycle T2, the positioning means 2b performs GPS positioning and acquires position information (step S12). After that, the positioning unit 2b stores the positional information and the positioning time in association with each other in the information storage unit 2d, and resets the T2 timer 2m to return to the initial value (step S13).

  When the count value of the T1 timer reaches the transmission cycle T1, the position notification means 2e extracts the latest position information stored in the information storage means 2d and transmits it to the distribution server 3 (step S15). In this case, information such as positioning time and positioning cycle T2 is transmitted together with the position information.

  When the distribution control means 3c of the distribution server 3 acquires the position information from the portable terminal 2 (step S21), the latitude and longitude specified from the acquired position information, that is, the positioning position is one of a plurality of distribution areas. It is determined whether it is in the distribution area. When it is determined that the positioning position is in any one of the distribution areas, the distribution area including the positioning position is specified as the located area. Further, the distribution control means 3c extracts the content information and content position information corresponding to the located area from the content information storage means 3a and distributes (transmits) them to the portable terminal 2 (step S22). Note that if there is no area, information indicating that there is no area is transmitted to the mobile terminal 2. Steps S21 and S22 correspond to a content information transmission step.

  Here, when the distribution server 3 distributes the same content information as the previously distributed content information, the distribution server 3 may stop the distribution of the content information for one time. As a result, it is possible to efficiently distribute content information by preventing the distribution of duplicate content information.

  When the portable terminal 2 receives the content information and the content position information from the distribution server 3 (step S16), the output control unit 2c associates the received content information with the content position information and stores them in the information storage unit 2d. (Step S17).

  The portable terminal 2 repeatedly executes the processes in steps S11 to S17 described above, and the distribution server 3 executes the processes in steps S21 and S22. That is, the mobile terminal 2 repeatedly performs GPS positioning at time intervals along the positioning cycle T2, and repeatedly transmits the latest position information to the distribution server 3 at time intervals along the transmission cycle T1. In the distribution server 3, the positioning position is specified based on the position information acquired from the mobile terminal 2, and if the position is within the distribution area, the distribution area is specified as the existing area, and the content information corresponding to the existing area and The content position information is transmitted to the mobile terminal 2. The mobile terminal 2 that has received the content information stores the content information in the information storage unit 2d in association with the reception time.

  Next, an operation procedure when content information is output by the mobile terminal 2 will be described with reference to FIG. FIG. 6 is a flowchart showing an operation procedure related to output of content information.

  In the portable terminal 2, the output cycle T3 is set in advance so as to be shorter than the positioning cycle T2. For example, when the positioning cycle T2 is 5 minutes, the output cycle T3 is set to 1 minute.

  The output control means 2c monitors the T3 timer 2n, and when the count value of the T3 timer 2n reaches the output cycle T3 (step S31), it is closest to the latest position information stored in the information storage means 2d. Content information corresponding to the content position information is extracted (step S32). Thereafter, the output control means 2c performs screen display switching in order to display the extracted new content information on the screen, and then resets the T3 timer 2n. Note that the output control means 2c, in addition to the content information corresponding to the content position information closest to the latest position information, among the plurality of content information stored in the information storage means 2d, in the order closest to the latest position information. The content information corresponding to the content position information may be extracted, and the content information may be displayed on the output device 25 such as a screen in the extracted order.

  Next, with reference to FIG.7 and FIG.8, the operation | movement procedure regarding the setting of a transmission period is demonstrated. FIG. 7 is a flowchart showing an operation procedure regarding setting of a transmission cycle in the distribution server. FIG. 8 is a diagram showing the relationship between the positioning position and the nearest delivery area, where (a) shows the case where the distance from the positioning position to the nearest delivery area is greater than or equal to a predetermined threshold, and (b) The case where the distance from a positioning position to the nearest delivery area is less than a predetermined threshold is shown. The setting of the transmission cycle T1 assumes a state where the user of the mobile terminal 2 is moving in a car.

  Position information is repeatedly transmitted from the portable terminal 2 (step S15). When there is no service area, that is, when the mobile terminal 2 does not exist in any delivery area, the transmission cycle setting means 3b of the delivery server 3 determines the distance to the delivery area Ar closest to the positioning position P. D, for example, the distance D to the boundary of the distribution area Ar is calculated (step S42).

  Thereafter, when the distance D calculated in step S42 is a predetermined threshold Th, for example, 40 km or more (see FIG. 8A), the transmission cycle setting means 3b sets “A” as the transmission cycle T1, for example, 30 minutes. Is registered (step S44), and if it is less than the predetermined threshold Th (see FIG. 8B), “B”, for example, 10 minutes is registered as the transmission cycle T1. “B” is a time interval longer than the positioning cycle T2 of the mobile terminal 2, and corresponds to a reference time interval. “A” is a longer time interval than “B”. In the present embodiment, it is assumed that the user of the mobile terminal 2 is moving by car. In this case, for example, if the vehicle is traveling at 80 km / h on an expressway, it will reach 40 km in 30 minutes. Therefore, the threshold is set to 40 km, “A” that is the time interval of the longer transmission cycle T1 is 30 minutes, and “B” that is the reference time interval of the shorter transmission cycle T1 is 10 minutes.

  Thereafter, the transmission cycle setting means 3b transmits the setting instruction information of the transmission cycle T1 to the portable terminal 2 in order to set the registered transmission cycle T1 in the portable terminal 2 (step S46). In the distribution server 3, each process of step S41 to step S46 is repeatedly executed. Each process from step S41 to step S46 corresponds to a transmission cycle setting step.

  The position notification means 2e of the portable terminal 2 sets “A” or “B” so that the transmission cycle T1 according to the setting instruction information is obtained every time the setting instruction information is received (step S51).

  According to the above distribution server 3, portable terminal 2, distribution system 1, and distribution method, the transmission cycle T <b> 1 of the position information transmitted from the portable terminal 2 can be managed on the distribution server 3 side. The distribution server 3 is responsible for transmitting the content information corresponding to the position information. When the distribution server 3 can manage the transmission cycle T1 of the position information, the content information to be transmitted to the portable terminal 2 and the transmission cycle T1 are obtained. The distribution server 3 can efficiently transmit content information, and the mobile terminal 2 can efficiently receive content information. In particular, by suppressing transmission of useless location information from the mobile terminal 2, it is possible to reduce the consumption of the battery 29a of the mobile terminal 2 and the tightness of network communication.

  Furthermore, the transmission cycle setting means 3b sets the transmission cycle T1 so as to be longer than the positioning cycle T2. Therefore, it is suppressed that the same position information as one positioning result is repeatedly transmitted to the distribution server 3 among the positioning periodically executed by the mobile terminal 2, and the same content information is transmitted to the mobile terminal. 2 is reduced from being transmitted many times.

  Further, in the distribution system 1 described above, when the distance D from the positioning position P of the mobile terminal 2 to the nearest distribution area Ar is equal to or greater than a predetermined threshold Th, the transmission cycle T1 is longer than the reference time interval “B”. “A” is set. When the distance from the positioning position P to the nearest delivery area Ar is equal to or greater than the predetermined threshold Th, it can be determined that the distance from the nearest delivery area Ar is larger than the case where the distance is less than the predetermined threshold Th. There is room in the time to reach Ar. Therefore, by making the transmission cycle T1 longer than the reference time interval when it is equal to or greater than the predetermined threshold value Th, transmission of useless position information from the portable terminal 2 is reduced, and efficient transmission of content information becomes possible. .

  Furthermore, in the present embodiment, the content information is output at an output cycle T3 that is shorter than the positioning cycle T2, and therefore the number of times of notification of the content information can be increased as compared with outputting at a cycle longer than the positioning cycle T2.

  Next, with reference to FIG. 9, the operation | movement procedure regarding the change of the positioning period T2 in the portable terminal 2 and the change of the transmission period T1 is demonstrated. FIG. 9 is a flowchart showing an operation procedure relating to the change of the positioning cycle T2 and the change of the transmission cycle T1 according to the remaining battery level.

  In the portable terminal 2, the battery remaining amount detecting means 2h periodically detects the remaining amount of the battery 29a of the power supply unit 29 (step S61). The transmission cycle changing unit 2g and the positioning cycle changing unit 2f monitor the detection value by the battery remaining amount detecting unit 2h (step S62).

  The transmission cycle changing means 2g changes the setting of the transmission cycle T1 that has already been set according to the instruction from the distribution server 3 according to the remaining battery level. That is, when the remaining battery level is high, the transmission cycle T1 is shortened to enable frequent transmission, and when the remaining battery level is low, the transmission cycle T1 is set to suppress battery consumption. Further, the positioning cycle changing unit 2f changes the positioning cycle T2 so that the positioning cycle T2 is shorter than the transmission cycle T1 set and changed by the transmission cycle changing unit 2g.

  Specifically, when the detection value by the remaining battery level detection means 2h is ½ or more of the charge completion state, the transmission period changing means 2g is set to “C”, for example, 10 minutes as the transmission period T1. Then, the positioning cycle changing means 2f changes the setting so that the positioning cycle T2 becomes “X” shorter than “C”, for example, 5 minutes (step S63). In addition, when the remaining battery level is less than 1/2 of the charge completion state and 1/3 or more, the transmission cycle changing unit 2g changes the setting to “D”, for example, 30 minutes as the transmission cycle T1. The positioning cycle changing means 2f changes the setting so that the positioning cycle T2 is “Y” shorter than “D”, for example, 15 minutes (step S64). When the remaining battery level is less than 1/3 of the charging completion state, the transmission cycle changing means 2g changes the setting to “E”, for example, 60 minutes as the transmission cycle T1, and the positioning cycle changing means 2f The setting is changed so that the positioning cycle T2 is “Z” shorter than “E”, for example, 30 minutes (step S65).

  As described above, the mobile terminal 2 changes the transmission cycle T1 set by the transmission cycle setting unit 3b and the positioning cycle according to the transmission cycle T1 changed by the transmission cycle changing unit 2g. With the positioning cycle changing means 2f for changing the setting of T2, the setting change of the transmission cycle T1 and the setting change of the positioning cycle T2 according to the changed transmission cycle T1 can be performed. Content information can be received.

  In particular, the portable terminal 2 includes a battery remaining amount detecting unit 2h, and the transmission cycle changing unit 2g changes the setting of the transmission cycle T1 according to the remaining amount detected by the remaining battery level detecting unit 2h, and changes the positioning cycle. The means 2f changes the positioning period T2 so as to be shorter than the transmission period T1 changed by the transmission period changing means 2g. As described above, the transmission cycle T1 is changed according to the remaining amount of the battery 29a, and the positioning cycle T2 is changed to be shorter than the transmission cycle T1 after the setting change. As a result, the battery 29a of the mobile terminal 2 is changed. Consumption is suppressed to a minimum, which is effective in preventing the waste of the battery, and the usage time of the portable terminal 2 by one charge can be extended. Note that the positioning cycle changing unit 2f may change the setting of the positioning cycle T2 to be equal to the transmission cycle T1 changed by the transmission cycle changing unit 2g.

  In this embodiment, the time interval is shortened in the order of the transmission cycle T1, the positioning cycle T2, and the output cycle T3, and can be set independently. As a result, it is possible to download the latest content information and appropriately display it on the screen while minimizing the consumption of the battery 29a of the mobile terminal 2 and the network load.

  In this embodiment, the positioning cycle T2 is changed based on the transmission cycle T1 whose setting has been changed. Conversely, after the positioning cycle T2 has been changed, the positioning cycle T2 is changed based on the changed positioning cycle T2. Thus, the transmission cycle T1 may be set and changed. Further, in this embodiment, the setting is changed so that the positioning period T2 is shorter than the transmission period T1, but the setting is changed so that the transmission period T1 and the positioning period T2 are the same period. May be.

  Next, with reference to FIG. 10, an operation procedure regarding a modified example of the output of content information in the mobile terminal 2 will be described. FIG. 10 is a flowchart showing an operation procedure in the case of outputting content information on the screen by a user operation input.

  The output control means 2c of the portable terminal 2 monitors the T3 timer 2n (step S71). Here, when the count value of the T3 timer 2n reaches the output cycle T3, the output control means 2c extracts the latest content information stored in the information storage means 2d (step S73). Thereafter, the output control means 2c displays the extracted content information on the screen (step S74), and resets the T3 timer 2n (step S75).

  Further, the output control means 2c accepts an operation input for output using the operation accepting means 2j by the user even when the count value of the T3 timer 2n has not reached the output cycle T3 (step S72). ), Content information corresponding to the content position information closest to the latest position information stored in the information storage means 2d is extracted (step S73). Thereafter, the output control means 2c displays the extracted content information on the screen (step S74), and resets the T3 timer 2n (step S75).

  In this modification, the content information is output in response to the user's input operation, so that the convenience of the user can be improved, and the T3 timer 2n is reset when the content information is output by the user's input operation. Therefore, immediately after the content information is output, output of the same content information due to the elapse of the output cycle T3 is prevented.

(Second Embodiment)
Next, with reference to FIG.11 and FIG.12, the delivery system 1B which concerns on 2nd Embodiment is demonstrated. In addition, about the delivery system 1B and the portable terminal 2B, the same code | symbol is attached | subjected in a figure and description in the same or equivalent element as the delivery system 1 and the portable terminal 2 which concern on 1st Embodiment, and the description is abbreviate | omitted. . Moreover, since the structure of the delivery server 3 which concerns on this embodiment is the same as the delivery server 3 which concerns on 1st Embodiment, it attaches | subjects the same code | symbol in a figure and description, and abbreviate | omits the description.

  FIG. 11 is a diagram illustrating a functional configuration of a distribution system 1B according to the second embodiment. As shown in FIG. 11, the distribution system 1 </ b> B includes a mobile terminal 2 </ b> B and a distribution server 3.

  Similar to the portable terminal 2 according to the first embodiment, the portable terminal 2B includes a communication unit 2a, a positioning unit 2b, an output control unit 2c, an information storage unit 2d, a position notification unit 2e, and a positioning cycle changing unit as functional configurations. 2f, a transmission period changing unit 2g, a battery remaining amount detecting unit 2h, an operation receiving unit 2j, a T1 timer 2k, a T2 timer 2m, and a T3 timer 2n. Furthermore, the portable terminal 2B includes terminal opening / closing detection means 2p.

  The terminal open / close detection means 2p is in an open state in which content information is output, specifically, in a state in which the mobile terminal 2B is opened and content information is being displayed from the output device 25, or the output of content information is stopped. In the closed state, specifically, whether the portable terminal 2B is closed and the content information is not displayed from the output device 25 is detected.

  Next, an operation procedure relating to the change of the positioning cycle T2 and the change of the transmission cycle T1 in the mobile terminal 2B will be described with reference to FIG. FIG. 12 is a flowchart showing an operation procedure regarding the change of the positioning cycle T2 and the change of the transmission cycle T1 according to the open / close state of the mobile terminal 2B.

  In the portable terminal 2B, the terminal opening / closing detection means 2p detects the opening / closing state of the portable terminal 2B, and the transmission period changing means 2g and the positioning period changing means 2f monitor the opening / closing state detected by the terminal opening / closing detection means 2p. (Step S81).

  The positioning cycle changing means 2f changes the setting of the positioning cycle T2 that has already been set according to the open / closed state of the terminal open / close detecting means 2p. That is, when the terminal opening / closing detection means 2p is in the open state, the positioning cycle T2 is shortened in order to enable frequent transmission (step S82), and unnecessary when the terminal opening / closing detection means 2p is in the closed state. The positioning cycle T2 is lengthened in order to suppress battery consumption associated with the operation process (step S83). Further, the transmission cycle changing unit 2g changes the setting of the transmission cycle T1 so that the transmission cycle T1 is longer than the positioning cycle T2 set and changed by the positioning cycle changing unit 2f (steps S82 and S83).

  Specifically, when the terminal opening / closing detection means 2p is in the open state, the positioning cycle changing means 2f changes the setting so that the positioning cycle T2 is “X”, for example, 5 minutes, and the transmission cycle changing means 2g transmits The setting is changed so that the period T1 is “C” longer than “X”, for example, 10 minutes (step S82). When the terminal open / close detection unit 2p is in the closed state, the positioning cycle changing unit 2f changes the setting to “Y” as the positioning cycle T2, for example, 15 minutes, and the transmission cycle changing unit 2g is set as the transmission cycle T1. The setting is changed so that “D” is longer than “Y”, for example, 30 minutes (step S83).

  As described above, in the mobile terminal 2B, the positioning cycle T2 and the transmission cycle T1 can be set and changed according to the open / close state. Therefore, for example, in the closed state, the output of the content information is stopped, so that the setting can be changed so that the positioning cycle T2 is longer than that in the open state. Then, by changing the setting to increase the transmission cycle T1 in accordance with the setting change of the positioning cycle T2, efficient positioning can be performed while reducing the number of transmissions per predetermined time and suppressing battery consumption.

  In this embodiment, after changing the positioning cycle T2, the transmission cycle T1 is changed based on the changed positioning cycle T2, but conversely after changing the transmission cycle T1. The positioning cycle T2 may be changed based on the transmission cycle T1 whose setting has been changed. In the present embodiment, the transmission cycle T1 is set to be longer than the positioning cycle T2. However, the positioning cycle T2 and the transmission cycle T1 may be the same cycle.

(Third embodiment)
Next, a distribution system 1 </ b> C according to the third embodiment will be described with reference to FIGS. 13, 14, and 15. In addition, about the distribution system 1C and the portable terminal 2C, the same code | symbol is attached | subjected in a figure and description in the same or equivalent element as the distribution system 1 and the portable terminal 2 which concerns on 1st Embodiment, and the description is abbreviate | omitted. . Moreover, since the structure of the delivery server 3 which concerns on this embodiment is the same as the delivery server 3 which concerns on 1st Embodiment, it attaches | subjects the same code | symbol in a figure and description, and abbreviate | omits the description.

  FIG. 13 is a diagram illustrating a functional configuration of a distribution system 1C according to the third embodiment. As illustrated in FIG. 13, the distribution system 1 </ b> C includes a mobile terminal 2 </ b> C and a distribution server 3.

  As with the portable terminal 2 according to the first embodiment, the portable terminal 2C has a communication unit 2a, a positioning unit 2b, an output control unit 2c, an information storage unit 2d, a position notification unit 2e, and a positioning period changing unit as functional configurations. 2f, a transmission period changing unit 2g, a battery remaining amount detecting unit 2h, an operation receiving unit 2j, a T1 timer 2k, a T2 timer 2m, and a T3 timer 2n. Furthermore, the portable terminal 2C includes a positioning history storage unit 2r, a moving speed estimation unit 2s, and a cycle determination table storage unit 2t.

  The information storage unit 2d has a function of storing past positioning time information and position information in association with each other and storing it as a positioning history, and corresponds to a positioning history storage unit.

  The moving speed estimation unit 2s has a function of estimating the moving speed of the mobile terminal 2C as an absolute speed or a relative speed. As a method for estimating the moving speed, for example, a method using a GPS positioning history, a method based on the switching frequency of a connected base station (cell), a method based on time variation of facing, and the like can be applied. The method using the GPS positioning history has a merit that it is easy to implement because it is a system that originally performs GPS periodic positioning. On the other hand, this method has a demerit that the followability with respect to the movement speed change from the quasi-static state (for example, the movement speed is less than 2 km / h) is low. In addition, the method based on the switching frequency of the connection destination base station (cell) has an advantage that the followability to the speed change is relatively high because the speed estimation does not depend on the GPS positioning cycle. On the other hand, this method has a demerit that the estimation accuracy of the moving speed becomes rough because the cell radius differs depending on the base station. In addition, the method based on the time variation of the facing has an advantage that the speed change can always be monitored. On the other hand, this method has a demerit that the moving speed estimation accuracy in the low speed range becomes coarse. The estimation method of the moving speed can be determined as appropriate in consideration of the above advantages and disadvantages.

  As shown in FIG. 15, the cycle determination table storage unit 2t stores a cycle determination table Ta1. In the cycle determination table Ta1, the estimated moving speed of the mobile terminal 2C, the positioning cycle, and the transmission cycle are stored in association with each other. For example, when the estimated moving speed is in the quasi-stationary state, the positioning cycle is defined as 10 minutes and the transmission cycle is defined as 15 minutes. When the estimated moving speed is 2 km / h or more and less than 10 km / h, the positioning period is defined as 6 minutes and the transmission period is defined as 11 minutes. When the estimated moving speed is 10 km / h or more and less than 60 km / h The positioning cycle is defined as 3 minutes and the transmission cycle is defined as 8 minutes. When the estimated moving speed is 60 km / h or more, the positioning cycle is defined as 1 minute and the transmission cycle is defined as 6 minutes. In the present embodiment, the transmission cycle is defined to be longer than the positioning cycle, but the positioning cycle and the transmission cycle may be the same cycle.

  Next, with reference to FIG. 14, the operation procedure regarding the change of the positioning cycle and the change of the transmission cycle in the portable terminal 2C will be described. FIG. 14 is a flowchart showing an operation procedure related to the change of the positioning cycle and the change of the transmission cycle according to the estimated moving speed of the mobile terminal 2C.

  In the portable terminal 2C, the movement speed estimation means 2s estimates the movement speed of the portable terminal 2C from a plurality of recent positioning histories among the positioning histories accumulated by the information accumulation means 2d (step S91).

For example, as shown in FIG. 16A, it is assumed that the mobile terminal 2C has moved from the previous positioning position P1 to the latest positioning position P0. Here, the distance from the positioning position P1 to the positioning position P0 is “d”, the positioning time of the positioning position P1 is “Tm1”, and the positioning time of the positioning position P2 is “Tm0”. The estimated moving speed V in this case is obtained from the following equation (1).
V = d / (Tm0−Tm1) (1)

Further, as shown in FIG. 16B, it is assumed that the mobile terminal 2C has moved from the previous positioning position P2 to the previous positioning position P1, and further moved to the latest positioning position P0. Here, the distance from the positioning position P2 to the positioning position P1 is “d1”, and the distance from the positioning position P1 to the positioning position P0 is “d2”. The positioning time at the positioning position P2 is “Tm2”, the positioning time at the positioning position P1 is “Tm1”, and the positioning time at the positioning position P0 is “Tm0”. The estimated moving speed V in this case is obtained from the following equation (2).
V = {d0 / (Tm0-Tm1) + d1 / (Tm1-Tm2)} / 2 (2)

  Next, the positioning cycle changing means 2f changes the setting of the positioning cycle that has already been set according to the moving speed estimated by the moving speed estimating means 2s. That is, the positioning cycle changing unit 2f refers to the cycle determination table 2t stored in the cycle determination table storage unit 2t, extracts the positioning cycle by setting the estimated moving speed as the search key, and becomes the extracted positioning cycle. Change the setting as follows.

  Specifically, the positioning cycle changing means 2f changes the setting so that the positioning cycle is 10 minutes (step S93) when the estimated moving speed is quasi-stationary, that is, less than 2 km / h (step S92). . If the estimated moving speed is not in the quasi-stationary state but is 2 km / h or more and less than 10 km / h, the setting is changed so that the positioning cycle is 6 minutes (step S95). If the estimated moving speed is not in the quasi-stationary state and is 10 km / h or more and less than 60 km / h, the setting is changed so that the positioning cycle is 3 minutes (step S96). If the estimated moving speed is not quasi-stationary and is 60 km / h or higher, the setting is changed so that the positioning cycle is 1 minute (step S97).

  Further, the transmission cycle changing unit 2g changes the setting of the transmission cycle that has already been set according to the moving speed estimated by the moving speed estimating unit 2s. That is, the transmission cycle changing unit 2g refers to the cycle determination table 2t stored in the cycle determination table storage unit 2t, extracts the transmission cycle by setting the estimated movement speed as a search key, and becomes the extracted transmission cycle. Change the setting as follows.

  Specifically, the transmission cycle changing means 2g is configured so that the transmission cycle becomes longer than the positioning cycle “10 minutes” when the estimated moving speed is in a quasi-stationary state, that is, less than 2 km / h (step S92). The setting is changed to minutes (step S93). Further, when the estimated moving speed is not in the quasi-stationary state but is 2 km / h or more and less than 10 km / h, the transmission period is changed to 11 minutes so that the transmission period becomes longer than the positioning period “6 minutes” ( Step S95). Further, when the estimated moving speed is not in the quasi-stationary state but is 10 km / h or more and less than 60 km / h, the setting is changed to 8 minutes so that the transmission period becomes longer than the positioning period “3 minutes” (step) S95). If the estimated moving speed is not quasi-stationary and is 60 km / h or higher, the transmission period is changed to 6 minutes so as to be longer than the positioning period “1 minute” (step S97).

  In the present embodiment, the setting is changed so that the transmission period is longer than the positioning period, but the setting may be changed so that the transmission period and the positioning period are the same.

  In the above description, the setting method of the positioning cycle and the transmission cycle has been described by taking the moving speed estimation method using the GPS positioning history as an example. However, the moving method is based on the switching frequency of the connected base station (cell). Estimate the speed, change the setting of the positioning period and transmission period according to the estimated moving speed, or estimate the moving speed by a method based on the time change of fading, and the positioning period and transmission period according to the estimated moving speed You may change the setting.

  For example, as shown in FIG. 17 (a), a period determination table Ta2 in which the estimated moving speed and the positioning period are associated with the cell switching frequency is stored in the period determining table storage means 2t. The means 2s refers to the period determination table Ta2 when the cell switching frequency is N times or more, and estimates a high speed movement as a relative speed, and when the cell switching frequency is less than N times per minute. Refers to the period determination table Ta2 and estimates a low speed movement as a relative speed. Next, the positioning cycle changing means 2f changes the positioning cycle so that the positioning cycle becomes “α1” or “α2” corresponding to high speed or low speed movement. On the other hand, the transmission cycle changing unit 2g changes the transmission cycle so that the same period as the positioning cycle changed by the positioning cycle changing unit 2f or the cycle becomes longer. When the transmission cycle is defined in the cycle determination table Ta2 in association with the estimated moving speed, the transmission cycle setting is changed first, and the same cycle as the changed transmission cycle or the cycle is shortened. The positioning cycle may be set and changed so that

  Further, as shown in FIG. 17B, a period determination table Ta3 in which the estimated movement speed and the positioning period are associated with the fading time fluctuation is stored in the period determination table storage unit 2t, for example, the movement speed estimation The means 2s refers to the period determination table Ta2, and when the fading time fluctuation is equal to or higher than the first threshold “L2”, the means 2s estimates that the speed is high (150 km / h or higher) and is less than the first threshold “L2”. When the second threshold value is “L1” or more, it is estimated as medium speed (less than 150 km / h, 60 km / h or more), and when it is less than the second threshold value “L1”, it is low speed (less than 60 km / h). ). Next, when the estimated moving speed is estimated to be high, the positioning period changing unit 2f changes the positioning period so that the positioning period becomes “β1 minutes”, and the estimated moving speed is estimated to be medium. In this case, the positioning cycle is set and changed so that the positioning cycle becomes “β2 minutes”, and when the estimated moving speed is estimated to be low, the positioning cycle is set and changed so that the positioning cycle becomes “β3 minutes”. . In this case, the transmission cycle changing unit 2g changes the transmission cycle so that the same period as the positioning cycle changed by the positioning cycle changing unit 2f or the cycle becomes longer. When the transmission cycle is specified in the cycle determination table Ta2 in association with the estimated moving speed, the transmission cycle setting is changed first so that the same cycle as the transmission cycle whose setting has been changed or the cycle becomes shorter. The positioning cycle may be changed.

  As described above, in the mobile terminal 2C, the positioning cycle and the transmission cycle can be set and changed according to the estimated moving speed. Therefore, for example, comparing the current movement speed estimated from the recent plurality of positioning histories with the movement speed estimated in the past, if the current movement speed is faster, the change in the positioning position becomes faster. Change the setting to shorten the cycle. In addition, by performing a setting change that shortens the transmission period in accordance with the setting change of the positioning period, it becomes possible to perform highly accurate positioning and efficient content information reception.

  In addition, this invention is not limited only to said embodiment. For example, in the present embodiment, the aspect in which content information is output periodically has been described as an example, but content information may be output irregularly. For example, the content information may not be displayed when the cellular phone is closed, such as a folding cellular phone, and the latest content information may be displayed only when the cellular phone is opened.

A location notification step in which the mobile station transmits the location information to the distribution server in the transmission cycle set in the transmission cycle setting step;
A content information transmission step in which the distribution server transmits content information corresponding to position information transmitted from the mobile station to the mobile station in accordance with the transmission cycle;
An information receiving step in which the mobile station receives content information corresponding to the location information from the distribution server and receives content location information for specifying a location provided by the content information;
An information accumulation step in which the mobile station stores a plurality of pieces of content information received from the distribution server in association with the content position information;
An output control step in which the mobile station outputs the content information stored by the information accumulation step at an output cycle shorter than the positioning cycle;
An operation accepting step in which the mobile station accepts a user input operation for outputting the content information;
A timer timing step in which the mobile station times the elapsed time of the output cycle , and
In the output control step, when it is determined that the output cycle has elapsed based on the time measured in the timer timing step, the output control step is closest to the latest position information transmitted from the mobile station to the distribution server. When the content information corresponding to the content position information is output, the time counting in the timer timing step is reset, and when the input operation is accepted in the operation accepting step, the mobile station sends the content information to the distribution server. A delivery method characterized by outputting the content information corresponding to the content location information closest to the latest location information transmitted and resetting the time count in the timer timing step.
