Description

  The present invention relates to a mobile terminal, a message management apparatus, a location identifier management apparatus, a message transmission / reception system, a message transmission / reception method, and a mobile terminal control program, and in particular, a movement for specifying a message browsing location and transmitting a message to a message recipient. The present invention relates to a terminal, a message management device, a location identifier management device, a message transmission / reception system, a message transmission / reception method, and a mobile terminal control program.

  In recent years, by using a mobile terminal such as a mobile phone or a PDA (Personal Digital Assistant), a message (hereinafter simply referred to as a message) such as an e-mail or a short message can be transmitted and received. When transmitting a message, a technique is generally known in which a message sender designates a transmission time of the message and transmits the message to the message recipient at the designated time. In such message transmission in the prior art, distribution control is performed at the time designated by the message sender.

  By the way, in addition to designating a time, it may be possible to send a message that can be viewed for the first time when a specific location is reached. In such a case, according to the above-described conventional technology, no consideration is given to the location where the message is received, so the message sender needs to guess the reception time. That is, when a message sender wants a message recipient to receive a message at a specific location, the message sender estimates the time to reach the specific location from the behavior of the message recipient, specifies the time, and sends the message. There was a need to send.

In order to receive an appropriate message at an appropriate location, it is considered that the receiving location can be designated on the transmission side. As techniques for specifying the message reception location in this way, there are those described in Patent Document 1 and Patent Document 2.
In the technique described in Patent Document 1, a transmission message is transmitted to a base station provided at a position corresponding to a transmission location, and when the base station is successfully linked to a portable terminal, the message is sent to the portable terminal. Is sending.

In the technique described in Patent Document 2, when a message specifying a reception location is transmitted, the server receives position information of the receiving terminal, and determines whether or not the specified reception location is within the range. And when it exists, it sends a message. In this document, the mobile terminal itself acquires position information by GPS (Global Positioning System), and transmits the acquired position information to a server.

Referring to the figure, this program is activated when a location identifier and a message identifier are acquired (step S10), and periodically acquires position information (step S11). Then, the acquired position information is compared with the place identifier (step S12). As a result of this comparison, if the two match, the message identifier is transmitted to the message management device to request message transmission (step S13). The request by transmitting this message identifier is a request for making it possible to view the entire message.
If the comparison result in step S12 does not match, the position information is continuously acquired periodically (step S12 → S11), and the acquired position information is compared with the location identifier (step S12).

As described above, this program allows a computer installed in a mobile terminal to acquire an acquisition unit that acquires a location identifier corresponding to a location specified on the message transmission side, and a position corresponding to the location identifier acquired by the acquisition unit.

Select the desired location from this list and specify the location identifier. The mobile terminal 1 transmits, together with the message, an address for identifying the mobile terminal 2 to which the message is to be transmitted and a designated location identifier to the message management apparatus 102 (S93).
The message management apparatus 102 stores the message (S94) received from the mobile terminal 1 in the message management table 21 and determines a message identifier (S95) that can identify the message. The message management apparatus 102 transmits the determined message identifier and location identifier to the mobile terminal 2 (S96).

(Receiving terminal processing)
FIG. 10 is a schematic diagram showing processing after the mobile terminal 2 as the receiving side terminal acquires the location identifier and the message identifier.
In the figure, the mobile terminal 2 periodically detects the current position of its own terminal. Then, when a person carrying the mobile terminal 2 goes to a specific place, the detected current position matches the position corresponding to the place identifier. In response to the detection of this match, the mobile terminal 2 transmits a message identifier to the message management apparatus 102 (S97).
Receiving this message identifier (S97 ′), the message management apparatus 102 searches the message management table based on the message identifier to obtain a message. The message management apparatus 102 transmits the acquired message (S98) to the mobile terminal 2. Thus, the mobile terminal 2 can receive the message (S98 ′).

  By the way, as a method for the receiving side terminal to acquire the current position of its own terminal, short-range wireless communication such as Bluetooth (registered trademark) as well as a method using a contactless tag such as RFID, a method using GPS, and the like. , A method of referring to an HLR (Home Location Register) and a VLR (Visitor Location Register) for managing the cell in which the cell is located, a method using a combination of the above methods, and the like.

(Summary)
The overall flow of processing by the message transmission / reception system described above will be described with reference to FIG. In the figure, the flow of processing by the mobile terminal 1, the message management apparatus 102, the location identifier management apparatus 103, and the mobile terminal 2 is shown.
First, the mobile terminal 1 transmits a location specifying mail for designating a location to transmit a message to the location identifier management device 103 (S111). In response to this, the location identifier management apparatus 103 transmits a list of location identifiers that can be specified to the mobile terminal 1 (S112).

Receiving this list, the mobile terminal 1 creates a message specifying a location identifier from the list and specifying an address for specifying the transmission partner, for example, an e-mail address, and transmits it to the message management apparatus 102 (S113) ).
The message management apparatus 102 that has received this message saves and registers the message (S114). Furthermore, the message management apparatus 102 transmits a message identifier for identifying the stored message and a location identifier specified in the mobile terminal 1 to the mobile terminal 2 that is the receiving terminal (S115).

The mobile terminal 2 that has received the message identifier and the location identifier (S116) acquires location information as it moves (S117) and compares it with the location identifier (S118). The position information acquisition process and the comparison process with the location identifier are continuously performed until the comparison result shows a match (S118 → S117...). If the comparison result indicates a match, the mobile terminal 2 transmits a message identifier to the message management apparatus 102 (S118 → S119).
The message management apparatus 102 that has received the message identifier searches the message management table based on the message identifier and acquires the message (S120). The message management apparatus 102 transmits the acquired message to the mobile terminal 2 (S121). As described above, the mobile terminal 2 can receive the message (S122).

In the above example, the message identifier, not the message itself, is transmitted to the receiving mobile terminal together with the location identifier. For this reason, when the current position of the terminal matches the position corresponding to the location identifier, the message can be acquired based on the message identifier by accessing the message management device 102. On the other hand, when the position corresponding to the location identifier cannot be reached, the message is not acquired, and therefore, it is unnecessary to store unnecessary information such as a message whose position does not match in the mobile terminal on the receiving side. There is.
In the example described above, the message management device 102 and the location identifier management device 103 are realized by separate devices, but their functions may be realized by a single physical device.

(Modification 1)
In this example, no message identifier is used. In this example, the following processing is performed.
When there is a transmission request from the transmission side terminal, the message management apparatus 102 transmits the location identifier and message specified on the transmission side to the reception side terminal. The receiving terminal that receives them does not display the received message immediately, but displays the message only when the received location identifier matches the current position. That is, since the entire transmitted message has already been sent completely, the entire message can be viewed at the designated location.

  In order to realize the above processing, for example, the receiving terminal may be operated using the program shown in FIG. In this figure, this program is started when a location identifier and a message are acquired (step S100), and acquires location information periodically (step S101). Then, the acquired position information is compared with the location identifier (step S102). As a result of this comparison, if both match each other, a message that has already been received is displayed (step S103). That is, as a result of the comparison, if both match, a process for enabling browsing of the entire message is performed, and the message can be browsed.

If the comparison results in step S102 do not match, the position information is continuously acquired periodically (step S102 → S101), and the acquired position information is compared with the location identifier (step S102).
In order to display the message for the first time when the acquired location information matches the location identifier without displaying it at the stage of receiving the message, it is only necessary to encrypt and release it. For example, an encrypted message may be received using the location identifier as a key, and decrypted using the location identifier as a key when the acquired location information matches the location identifier.
According to this example, since the message has already been received, if the location identifier matches the current location, even if the receiving terminal is outside the communication service range, the message is viewed when it reaches the location. can do.

(Modification 2)
In the first modification, the entire message is transmitted, but only a part of the message may be transmitted instead of the entire message. For example, only the message title may be transmitted. In this case, the following processing is performed.
When there is a transmission request from the transmission side terminal, the message management apparatus 102 transmits a part of the message to the reception side terminal in addition to the location identifier and the message identifier specified on the transmission side. The receiving terminal that receives them periodically acquires the current position. When the received location identifier matches the current position, the message can be acquired based on the message identifier by accessing the message management device 102 as a process for enabling browsing of the entire message. In this case, the entire message may be newly acquired, or only the difference between the already acquired part and the entire message may be acquired.

If the location identifier matches the current position but the user is out of the communication service area, a part of the already received message can be displayed and necessary information may be browsed.
On the other hand, if the position corresponding to the location identifier cannot be reached, no message is acquired.
As described above, according to this example, since a part of the message has already been received, it is possible to cope with the case where the receiving terminal is out of the communication service area, and a wasteful message such as a message whose position does not match. There is an advantage that it is not necessary to store information in the receiving terminal.

(Modification 3)
In the above example, a list of place identifiers that can be specified is acquired from the place identifier management apparatus 103, and the place identifier is designated at the transmission side terminal. However, the place name may be designated instead of the place identifier. good. In this case, the place identifier management apparatus 103 may be provided with a conversion function for converting a designated place name into a place identifier corresponding to the place. In this way, it is not necessary to send and receive the list, and the burden on the network can be further reduced.

(Message sending and receiving method)
In the message transmission / reception system described above, the following message transmission / reception method is adopted. That is, storing a message whose location is specified on the message sending side, sending information on the location and a message identifier for specifying the message to the message receiving side, and detecting on the message receiving side A message transmission / reception method including a step of performing processing for enabling browsing of the entire message when the current position matches the above place is employed.
By adopting such a method, when a message is transmitted by specifying a reception location, an excessive load is not applied to the base station or the server.
