Description

  The present invention relates to a message transmission apparatus that transmits a message to a communication terminal, and a message transmission method by the message transmission apparatus.

  Conventionally, a message registered in advance by a user on the incoming side has been transmitted to the terminal on the outgoing side that made the call. For example, when a user on the receiving side cannot respond to outgoing calls, a technique for transmitting a message registered in advance by a user on the terminal side to the terminal on the outgoing side is used in the answering machine function (for example, a patent) Reference 1).

JP 2006-148945 A

  As described above, the message transmitted to the terminal on the calling side may notify the status of the user on the called side, that is, the status of the user on the called side. However, as described above, in a mode in which the receiving user registers a message for the answering machine function transmitted to the calling terminal, the receiving user must always maintain the registered message. If the maintenance message is not properly performed by the user on the called side, the reliability of the message transmitted to the terminal on the calling side is lowered (the real-time nature of the situation of the notified user on the called side is lowered).

  The present invention has been made in view of the above, and appropriately transmits a message to a communication terminal such as a terminal on the transmission side without increasing the burden on the user who should input the message of the user on the reception side. It is an object of the present invention to provide a message transmission apparatus and a message transmission method that enable the above.

  In order to achieve the above object, a message transmission device according to the present invention is a message transmission device that transmits a message to a communication terminal, and is acquired by a message acquisition unit that acquires a message from a plurality of information sources, and a message acquisition unit. A similarity determination unit that determines whether or not the messages are similar to each other, a transmission message determination unit that determines a message to be transmitted from the message acquired by the message acquisition unit based on the determination by the similarity determination unit, and a transmission message Message transmitting means for transmitting the message determined by the determining means to the communication terminal.

  In the message transmission apparatus according to the present invention, a message that can be transmitted to a communication terminal from a plurality of information sources is acquired. Therefore, for example, messages such as disaster message boards, presence servers, schedulers, SNSs (Social Networking Services), and profile services are usually transmitted using information from information sources into which information is input. Thus, the user does not need to maintain a message only for message transmission, and the message is transmitted based on information input by the user as appropriate. In the message transmission device according to the present invention, a message to be transmitted is determined based on a determination as to whether or not a plurality of messages are similar. Therefore, only non-redundant messages can be sent to the communication terminal. As described above, according to the message transmission device of the present invention, it is possible to appropriately transmit a message to the communication terminal without increasing the burden on the user who should input the message.

  It is desirable that time information indicating the update time of the message is added to the message acquired by the message acquisition unit, and the transmission message determination unit determines a message to be transmitted based on the update time. According to this configuration, when a non-redundant message is used, a newly updated message can be transmitted, and a message can be further appropriately transmitted to the communication terminal.

  The transmission message determination means determines whether priority information indicating that the message should be transmitted with priority is added to the message acquired by the message acquisition means. If the priority information is added, the priority is given priority. It is desirable to be a message to be sent. According to this configuration, when there is a message to be transmitted with priority, the message can be reliably transmitted.

  Whether or not the message acquired by the message acquisition unit indicates whether or not the message can be transmitted according to the communication terminal is added, and the transmission message determination unit determines the message to be transmitted based on the availability information. It is desirable. According to this configuration, an appropriate message can be transmitted according to the communication terminal that is the message transmission destination.

  It is desirable that the message acquisition unit acquires the message from the information source as text data, and the message transmission unit converts the message from text data to voice data and transmits the message. According to this configuration, the input to the message transmission device can be text data, and the output from the message transmission device can be audio data.

  By the way, the present invention can be described as an invention of a message transmission apparatus as described above, and can also be described as an invention of a message transmission method as follows. This is substantially the same invention only in different categories, and has the same operations and effects.

  That is, the message transmission method according to the present invention is a message transmission method for transmitting a message to a communication terminal, and the message acquisition step for acquiring a message from a plurality of information sources is similar to the messages acquired in the message acquisition step. A determination step for determining whether or not the transmission message is determined, a transmission message determination step for determining a message to be transmitted from the message acquired in the message acquisition step, and a transmission message determination step based on the determination in the similarity determination step. A message transmission step of transmitting the received message to the communication terminal.

  According to the present invention, a user who inputs a message to be transmitted does not need to maintain a message only for message transmission, and the message is transmitted based on information input by the user as appropriate. Further, according to the present invention, since a message to be transmitted is determined based on a determination as to whether or not a plurality of messages are similar, only non-redundant messages can be transmitted to the communication terminal. As described above, according to the present invention, a message can be appropriately transmitted to a communication terminal without increasing the burden on the user who should input the message.

It is a sequence diagram which shows the process (message transmission method) performed at the time of transmission of a message with the message transmission apparatus which concerns on embodiment of this invention.

  Hereinafter, preferred embodiments of a message transmission device and a message transmission method according to the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and redundant description is omitted.

  FIG. 1 shows a message transmission apparatus 10 according to the present embodiment. The message transmission device 10 is included in the mobile communication network and is a device that transmits a message to the mobile communication terminal 20. More specifically, when the message transmitting apparatus 10 makes a call to perform telephone communication from the mobile communication terminal 20 to another mobile communication terminal 20, there is no response from the other mobile communication terminal 20. In this case, a message (registered in advance) from a user of another mobile communication terminal 20 is transmitted. For example, when the incoming mobile communication terminal 20 is in a disaster area, located outside the communication area, or is in a state where it cannot be answered because the power is turned off. The above message is sent.

  This message is, for example, a message indicating the status of a user of another mobile communication terminal 20 (incoming mobile communication terminal 20). A specific message to be transmitted will be described later. The user of the mobile communication terminal 20 on the calling side can know the status of the user of the mobile communication terminal 20 on the receiving side by referring to this message.

  The mobile communication terminal 20 is a device used by a user to connect to a mobile communication network and perform mobile communication. As described above, the mobile communication terminal 20 makes a call to another mobile communication terminal 20 by the mobile communication function, or accepts a call from another mobile communication terminal 20 to establish a call connection. It has a function to perform communication. The mobile communication terminal 20 can receive a message from the message transmission device 10 via the exchange 30 included in the mobile communication network. In FIG. 1, only the exchange 30 is depicted between the message transmitting apparatus 10 and the mobile communication terminal 20, but normally other apparatuses such as a base station and a radio control apparatus are provided.

  The mobile communication network is a communication network that provides a mobile communication function to the mobile communication terminal 20. The mobile communication network performs a process of accepting a call from the mobile communication terminal 20 to another mobile communication terminal 20 and establishing a call connection. In the call connection establishment process, when there is no response from the incoming mobile communication terminal 20 (for a certain period of time), the mobile communication network transmits the mobile communication on the outgoing side to the message transmitting device 10. A request is made to send a message to the terminal 20.

  The user status input server groups 41 to 45 shown in FIG. 1 serve as information sources for messages transmitted from the message transmitting apparatus 10 to the mobile communication terminal 20 as described above. The user status input server groups 41 to 45 may not be used only as message information sources, but may be used for respective services as described later. Further, the user status input server groups 41 to 45 may be provided independently of the mobile communication network, or may be devices included in the mobile communication network. The user status input server groups 41 to 45 are connected to the message transmission device 10 via a wired or wireless communication network or the like, and can exchange information with the message transmission device 10.

  As shown in FIG. 1, the user status input server groups 41 to 45 specifically correspond to a disaster message board 41, a presence server 42, a scheduler 43, an SNS 44, a profile (profile service) 45, and the like. The disaster message board 41 is a device that provides a user status to another user when a disaster occurs. For example, a message such as “It is safe” is registered from the user. The presence server 42 is a device that provides information (presence information) such as a user's situation and position to another user. For example, a message such as “I am in a smoking room” is registered from the user. The scheduler 43 is a device that manages or provides information on the user's schedule. For example, a message such as “breaking” is registered from the user.

  The SNS 44 is an apparatus that provides information for communication between users. For example, a message such as “Recruiting lovers!” Is registered from the user. The profile 45 is a device that provides the user's profile information to another user. For example, a message such as “Recruiting a lover!” Is registered from the user. The messages registered in the user status input server groups 41 to 45 are associated with information (for example, user ID) that identifies the user. In addition, a disclosure restriction may be set for each piece of information as will be described in more detail later. In addition, priority information indicating that transmission should be performed with priority may be added to each information. Note that the user status input server groups 41 to 45 do not necessarily need to use all of the above, and other than the above may be used, and there may be a plurality of information sources.

  Subsequently, functions of the message transmission apparatus 10 according to the present embodiment will be described in detail. As shown in FIG. 1, the message transmission device 10 includes a message accumulation unit 11, a message transmission request reception unit 12, a caller authentication unit 13, a similarity determination unit 14, a message editing unit 15, and a voice synthesis unit. 16 and a message reproduction unit 17.

  The message accumulation unit 11 is a message acquisition unit that acquires messages from the user status input server groups 41 to 45. The message aggregating unit 11 receives and acquires each user's message from the user status input server groups 41 to 45. The message accumulation unit 11 stores and accumulates the acquired messages in a message management database (not shown) for each user and each message. The message management database is held by the message accumulation unit 11. The message accumulation unit 11 stores the acquired message in the message management database, for example, in the format shown in FIG. The format shown in FIG. 2 is a format related to one message. That is, each information shown in FIG. 2 is stored for each message.

  “Message ID” is information for identifying each message. Each information is associated with “message ID”. “Destination user ID” is information for identifying a user who has registered the message (when the message is transmitted to the mobile communication terminal 20 on the outgoing side, the user becomes the user of the mobile communication terminal 20 on the incoming side). “Message reproducibility” is information indicating whether or not the message is a message that can be transmitted to the mobile communication terminal 20 on the transmission side. A message that can be transmitted to the originating mobile communication terminal 20 when the “message reproducibility” is “target”, and a message that is not transmitted to the originating mobile communication terminal 20 when “not applicable”. It shows that there is.

  The “user status input server” is a connection ID which is information indicating which user status input server 41 to 45 is the information source. The “update date / time allowable range” is information indicating a time limit for reproducing the message. “Message” is data of a message to be transmitted. Specifically, it is text data. “Update date and time” is information indicating the time when the message is updated. “Priority designation” is information indicating whether or not the message is preferentially transmitted. When “priority designation” is “priority”, it indicates that the message is to be transmitted with priority. When “priority designation” is “normal”, the message has priority. Indicates that it is not sent. “Public restriction” is information indicating whether or not the message is transmitted only to a specific mobile communication terminal 20 (user). When there is a “public restriction”, the “user authentication key” is information for identifying the mobile communication terminal 20 (the user) that transmits a message when there is a public restriction. These are a caller number (telephone number) of the communication terminal 20, an ID for identifying the terminal, voiceprint information, and the like. The “public restriction” and the “calling user authentication key” are permission information indicating whether or not the message can be transmitted according to the mobile communication terminal 20.

  Each information other than the above message except “message reproducibility” is added to the “message” and transmitted from the user status input servers 41 to 45 to the message transmitting apparatus 10. However, the “message ID” may be given by the message transmitting apparatus 10. In addition, regarding the setting information relating to the transmission of the message, “message reproducibility”, “update date / time allowable range”, “priority designation”, “public restriction”, and “originating user authentication key”, the message is sent to the message accumulation unit 11. After being stored, a change may be made according to the input to the message stacking unit 11. The storage of the message in the message accumulation unit 11 will be described later in detail with reference to the flowchart of FIG.

  Transmission of messages from the user status input server groups 41 to 45 to the message transmission device 10 may be performed spontaneously from the user status input server groups 41 to 45 side, or the message transmission unit 10 (the message accumulation unit 11 of the message transmission device 10). ) May be performed upon request. The timing of message transmission from the user status input server groups 41 to 45 to the message transmitting apparatus 10 is arbitrarily determined for each of the user status input server groups 41 to 45.

  For example, when there is a difference in message update by the user, such as SNS 44, profile 45, and blog, there is a risk of inadvertently increasing the processing load due to message transmission when the periodic period is set, and the message update timing by the user It is desirable that the transmission be adapted to Conversely, for the presence server 42 that collects location information of the mobile communication terminal 20, the message transmission timing is designed according to the processing capability of the server, so that the message is updated frequently. It is desirable to send messages in a regular cycle in the form of

  When there is no response from the mobile communication terminal 20 at the call destination (the destination side) to the call from the mobile communication terminal 20 (normal call), the message transmission request accepting unit 12 sends a message transmission device from the mobile communication network. 10 is a means for receiving a request to send a message to the caller mobile communication terminal 20 made by 10. When there is no response from the incoming mobile communication terminal 20, for example, the incoming mobile communication terminal 20 is located in an area where network congestion occurs such as a disaster area or near an event venue such as fireworks. The mobile communication terminal 20 on the receiving side is out of the communication range. The request from the mobile communication network to the message transmission device 10 includes information (for example, a telephone number) that identifies the mobile communication terminal 20 on the transmission side and the reception side. The message transmission request reception unit 12 outputs the received request to the caller authentication unit 13.

  In the present embodiment, the message transmitting apparatus 10 does not determine whether or not there is a response from the incoming mobile communication terminal 20, but the message transmitting apparatus 10 does not determine the response from the incoming mobile communication terminal 20. The presence / absence determination may be performed, and the message transmission process may be performed when it is determined that there is no response. The message is transmitted not only when there is no response from the incoming mobile communication terminal 20, but also the call connection between the outgoing mobile communication terminal 20 and the incoming mobile communication terminal 20 is not established. It may be performed also in the case of.

  Based on the information included in the request input from the message transmission request accepting unit 12, the caller authenticating unit 13 uses the message stored in the message management database of the message accumulating unit 11 to perform the caller's authentication. This is means for acquiring a message that is a candidate for transmission to the mobile communication terminal 20. The caller authenticating unit 13 sends a message associated with the mobile communication terminal 20 on the called side included in the request ("called user ID" associated with the message stored in the message management database of the message accumulating unit 11). Then, the information identifying the receiving mobile communication terminal 20 included in the request is acquired from the message accumulating unit 11 together with the additional information (message determined to indicate the same mobile communication terminal 20 (user)).

  The caller authenticating unit 13 determines whether or not the acquired message includes a message with “public restriction” “present”. If the caller authentication unit 13 determines that such a message is included, the caller authentication unit 13 identifies the “calling user authentication key” associated with the message and the mobile communication terminal 20 on the caller side included in the request. Compare with the information you want. As a result of the comparison, the caller authenticating unit 13 determines that the “calling user authentication key” and the information specifying the calling mobile communication terminal 20 indicate the same mobile communication terminal 20 (user). If so, it is assumed that the message is a candidate message to be transmitted to the mobile communication terminal 20 on the transmission side.

  As a result of the comparison, if it is determined that the “calling user authentication key” and the information specifying the mobile communication terminal 20 on the caller side do not indicate the same mobile communication terminal 20 (the user), the message is sent to the caller Are excluded from candidates to be transmitted to the mobile communication terminal 20. The caller authenticating unit 13 sets a message editing unit 15 to display a message with “None” as the “public restriction” in the acquired message and a message with “Public restriction” as the transmission candidate as described above. Output to. If the “calling user authentication key” is information relating to the user of the mobile communication terminal 20 such as voiceprint information, a connection is established between the message transmission device 10 and the mobile communication terminal 20 at the time of the above determination. Then, the data used for the determination from the mobile communication terminal 20 (in the case of voiceprint information, the voice data of the user of the mobile communication terminal 20 on the transmission side) is acquired and the above determination is performed. As described above, the caller authentication unit 13 is a function of a transmission message determination unit that determines a message to be transmitted to the mobile communication terminal 20 on the transmission side.

  The similarity determination unit 14 is a similarity determination unit that determines whether messages are similar to each other. As will be described later, the similarity determination unit 14 inputs a plurality of messages to be determined from the message editing unit 15 and makes a similar determination for each combination of input messages. An existing technique can be used to determine whether messages (text data) are similar to each other. For example, the similarity determination unit 14 holds a similar word database storing similar words in advance, and performs a similar word search using the similar word database. Among the entered messages, if there are messages that have the same message body, or verbs included in the message that are the same or similar to similar words, they are determined to be duplicate messages and the same as above A group of messages that are recognized as sex is a group of duplicate messages. The similarity determination unit 14 outputs information indicating the determination result to the message editing unit 15.

  The message editing unit 15 is a transmission message determination unit (one function) that determines a message to be transmitted to the mobile communication terminal 20 on the transmission side from the message input from the caller authentication unit 13. The message editing unit 15 outputs the message input from the caller authentication unit 13 to the similarity determination unit 14 and determines a message to be transmitted based on the similarity determination result between the messages by the similarity determination unit 14. A method for determining a message by the message editing unit 15 will be described in detail later. The message editing unit 15 edits the determined message (text data thereof) and outputs the edited message to the speech synthesis unit 16.

  The speech synthesizer 16 is means for converting a text data message input from the message editor 15 into speech data. That is, the speech synthesizer 16 is a function of a message transmission unit that transmits a message to the mobile communication terminal 20 on the transmission side. Conversion from text data to speech data is performed in the same manner as in conventional techniques such as speech synthesis. The voice synthesizer 16 outputs the converted voice data message to the message playback unit 17.

  The message reproduction unit 17 is a message transmission unit (one function) that transmits the message of the voice data input from the voice synthesis unit 16 to the mobile communication terminal 20 on the transmission side. The audio data is transmitted in the same manner as the conventional audio data transmission / reception via the mobile communication network. Here, the mobile communication terminal 20 that is a message transmission destination relates to information that identifies the mobile communication terminal 20 on the transmission side included in the request received by the message transmission request reception unit 12, and is a message reproduction unit. 17 acquires the information and transmits it.

  FIG. 3 shows a hardware configuration of the message transmission device 10. As shown in FIG. 3, the message transmission device 10 includes a central processing unit (CPU) 101, a random access memory (RAM) 102 and a read only memory (ROM) 103 that are main storage devices, a communication module 104 for performing communication, and The computer is configured to include a computer including hardware such as an auxiliary storage device 105 such as a hard disk. The functions of the message transmission device 10 described above are exhibited by the operation of these components by a program or the like. The above is the configuration of the message transmission device 10.

  Subsequently, processing (message transmission method) executed by the message transmission apparatus 10 according to the present embodiment will be described with reference to the sequence diagrams of FIGS. 4 and 5. First, processing for acquiring a message from the user status input server groups 41 to 45 will be described using the flowchart of FIG. Then, the process which transmits a message to the mobile communication terminal 20 of the transmission side is demonstrated using the flowchart of FIG.

  First, in the message transmitting apparatus 10, the message accumulating unit 11 receives and acquires a user message from the user status input server groups 41 to 45 (S01, message acquisition step). This acquisition is appropriately performed at the acquisition timing described above. Subsequently, the message aggregating unit 11 determines whether or not “update date and time” information is added to the message as additional information of the message (S02). When it is determined that the “update date / time” information is not included, the message collection unit 11 sets the time when the message is received as the “update date / time” of the message stored in the message management database. (S03).

  Subsequently, the message accumulating unit 11 determines whether or not the message is preferentially designated. Specifically, the message accumulation unit 11 determines whether or not “priority designation” information is added to the message as additional information of the message and “priority designation” is “priority” (S04). . If “priority designation” information is added to the message and it is determined that “priority designation” is “priority”, the message “priority designation” stored in the message management database is set to “priority”. It is set (S05). In addition, “message reproducibility” of another message (from the user status input server group 41 to 45) related to the same “arriving user ID” as the “arriving user ID” of the message already stored in the message management database. "Is not subject" (S06). This suppresses the reproduction of other messages when there is a priority designated message. If there are multiple messages for which “priority designation” is designated as “priority”, only “priority” messages with new “update date / time” are subject to reproduction, and other “priority” messages are subject to reproduction “subject”. "Outside".

  In S04, when it is determined that “priority designation” information is not added to the message, and “priority designation” information is added to the message, but “priority designation” is determined to be “normal”. If the message is stored, the message “priority designation” stored in the message management database is set to “normal” (S07).

The above processing enables message reproduction priority processing based on the following policy.
(1) When there is an urgent message regarding user message reproduction in a disaster or the like, priority is given to the message, and reproduction of other messages is suppressed.
(2) The reliability of the user status indicated by the message (compatibility with the actual user status) is defined to be higher as the message update date is newer. Accordingly, the priority of message reproduction without priority designation is higher as the message update date is newer.
(3) In a situation where a priority designated message does not need to be notified, when a priority designation message is received, for example, when a disaster does not occur even though the message is related to a disaster If a message is received with priority designation, there is a possibility that other messages are inhibited from being reproduced due to the unnecessary message. The following two methods can be considered as a method for avoiding this.

(Method 1) Control by the user status input servers 41 to 45 The user status input servers 41 to 45 that transmit the priority designation message transmit the message only when the message is in a useful situation, and the message becomes unnecessary. At this point, the message stored in the message management database of the message transmitting apparatus 10 is deleted.

(Method 2) Control by Message Transmitting Apparatus 10 The user status input servers 41 to 45 that transmit the priority specifying message notify the message transmitting apparatus 10 of the priority specifying condition. The message transmitting apparatus 10 treats the target message as a priority designation message only when the priority designation conditions are met.

Examples of the priority designation conditions include the following.
1. Specify whether or not priority designation of messages or reproduction designation is specified by specifying a period (date and time).
2. The number of times of message reproduction is designated, and the same message is designated for the designated number of reproduction times, priority is designated, or reproduction is prohibited for the same originating mobile communication terminal 20.
3. Specify according to the linkage with another status notification server. In this case, the message transmission device 10 receives information indicating the status of the mobile communication terminal 20 on the receiving side from the status notification server separately from the reception of the messages from the user status input servers 41 to 45, and based on the information. specify. Specifically, for example, when the user status input servers 41 to 45 are the disaster message boards 41 and the situation notification server is a location information management server that notifies information indicating the location of the mobile communication terminal 20 on the incoming side. It is done as follows. As a priority designation condition, priority designation is performed when information indicating the position of the mobile communication terminal 20 on the receiving side notified from the status notification server to the message transmission device 10 is in the Tokyo metropolitan area. This assumes that a major disaster has occurred in the Tokyo metropolitan area. The message transmission device 10 performs priority designation or reproduction of a message from the disaster message board 41 only when the incoming mobile communication terminal 20 is located in the Tokyo metropolitan area.

  Subsequently, returning to the flowchart of FIG. 4, the message accumulating unit 11 determines whether or not the information of the “originating user authentication key” is added to the message as additional information of the message (S08). When it is determined that the information on the “calling user authentication key” is added to the message, the message accumulating unit 11 determines whether the information on the “calling user authentication key” can be used for the authentication process. (S09). When it is determined that the information of the “originating user authentication key” can be used for the authentication process, the “public restriction” stored in the message management database by the message accumulation unit 11 of the message is set to “present”. (S10). When it is determined that the information of the “originating user authentication key” cannot be used for authentication processing, the message aggregating unit 11 performs an error response to the user status input servers 41 to 45 that are the transmission source of the message. The message registration process is canceled.

  If it is determined in S08 that the information of the “user authentication key” is not added to the message, the “public restriction” stored in the message management database by the message accumulation unit 11 of the message is set to “none”. It is set (S11).

  Subsequently, the message accumulating unit 11 has already stored in the message management database a message having the same “connection ID” and “destination user ID” as the additional information of the received message. It is determined whether it has been performed (S12). If it is determined that the message management database is not stored, the message accumulating unit 11 newly stores the received message together with the additional information in the message management database (S13). On the other hand, if it is determined that the message management database is stored, the message collection unit 11 deletes the already stored message and newly stores the received message together with the additional information in the message management database. (S13). The above is the processing for acquiring a message from the user status input server group 41 to 45.

  Subsequently, a process of transmitting a message to the mobile communication terminal 20 on the transmission side will be described using the flowchart of FIG. In this process, first, a call is made from the caller mobile communication terminal 20 to the callee mobile communication terminal 20 to the mobile communication network. Subsequently, in the mobile communication network, it is detected that there is no response from the incoming mobile communication terminal 20 for the call for a certain period of time. When there is a response from the incoming mobile communication terminal 20, normal communication processing such as establishment of a call connection is performed. In the mobile communication network, when it is detected that there is no response from the incoming mobile communication terminal 20 for a certain period of time, a message is transmitted from the mobile communication network to the message transmitting apparatus 10 to the outgoing mobile communication terminal 20. Make a request to do. In the message transmitting apparatus 10, the request is received by the message transmission request receiving unit 12 (S21). The request is output from the message transmission request reception unit 12 to the caller authentication unit 13.

  Subsequently, the caller authenticating unit 13 adds a message as a candidate to be transmitted from the message stored in the message management database of the message accumulating unit 11 to the mobile communication terminal 20 on the calling side according to the request. Acquired together with the information (S22). The message acquired here corresponds to information specifying the incoming mobile communication terminal 20 included in the request input from the message transmission request accepting unit 12 and the message stored in the message management database of the message accumulating unit 11. It is determined that the attached “destination user ID” indicates the same mobile communication terminal 20 (user).

  Here, messages whose “message reproduction possibility” is “not applicable” are not acquired. Further, when the threshold value of the “update date and time allowable range” of the message is compared with the current time and the threshold indicates an earlier time, the message is not acquired. The processing using the “update date / time allowable range” threshold may be performed as follows. In the message management database, regular maintenance (periodic auditing) is performed when the date changes. At that time, if the threshold of the “update date and time allowable range” of the message is compared with the current time, and the threshold indicates an earlier time, the message is deleted or “message playback” “Not applicable” is set to “not applicable” so that the message is not acquired.

  Subsequently, the caller authenticating unit 13 determines whether or not the acquired message includes a message having “public restriction” “present”. If it is determined that such a message is included, the caller authentication unit 13 identifies the “calling user authentication key” associated with the message and the calling mobile communication terminal 20 included in the request. The information to be compared is compared (S22). As a result of the comparison, if it is determined that the “calling user authentication key” and the information specifying the mobile communication terminal 20 on the caller side indicate the same mobile communication terminal 20 (user), caller authentication The message is set as a candidate message to be transmitted to the mobile communication terminal 20 on the transmission side by the unit 13.

  Subsequently, among the acquired messages, a message with “None” as “Public restriction” and a message with “Yes” as “Public restriction” as described above are sent from the caller authentication unit 13. The message is output to the message editing unit 15. Subsequently, the similarity determination unit 14 determines whether the messages are similar (S24, similarity determination step). As a result of the determination by the similarity determination unit 14, information indicating a message that is a duplicate message group is input from the similarity determination unit 14 to the message editing unit 15.

  If there is a duplicate message group, then the message editing unit 15 leaves only the message with the newest “update date / time” among those messages, from the candidates to be transmitted to the mobile communication terminal 20 on the caller side. Excluded (S25, message determination step). If there is no duplicate message group, the above exclusion process is not performed, and all the messages remaining at that time are candidates for transmission to the mobile communication terminal 20 on the transmission side.

  Subsequently, the message editing unit 15 rearranges the messages (text messages of “message”) that are candidates for transmission to the mobile communication terminal 20 on the calling side in the order of “update date and time” (S26). Subsequently, the message editing unit 15 adds a common message to these messages. The common message is always given when a message is transmitted to the mobile communication terminal 20 on the transmission side. For example, an announcement or guidance related to a service (message transmission) stored in the message editing unit 15 in advance is provided. Provided as part of the service of mobile network operators. However, in a case where there are few changes in the message, it is possible to add default voice data after performing voice synthesis as will be described later.

  The message (text message) edited in this way is output from the message editing unit 15 to the speech synthesis unit 16. Subsequently, the voice synthesizer 16 converts the text data message into voice data (S28, message transmission step). The converted voice data is output from the voice synthesis unit 16 to the message reproduction unit 17.

  Subsequently, the message playback unit 17 transmits the voice data message input from the voice synthesis unit 16 to the mobile communication terminal 20 on the transmission side (S29, message transmission step). In the mobile communication terminal 20 on the transmission side, the message that is voice data is received and played back. The user of the originating mobile communication terminal 20 listens to it, and based on the message input to the user status input server groups 41 to 45 by the user of the terminating mobile communication terminal 20, the receiving mobile communication terminal It is possible to know the status of 20 users.

  As described above, according to the present embodiment, messages such as the disaster message board 41, the presence server 42, the scheduler 43, the SNS 44, and the prof 45 are normally transmitted using information of information sources from which information is input. Is called. That is, according to the present embodiment, based on the current situation that the number of users who use a plurality of community services is increasing due to diversification of community services on the network, messages related to user statuses etc. from a plurality of information requests on the network Can be acquired and aggregated. Thereby, the user can transmit a message only by using the community service, and the user does not need to maintain a message only for message transmission. Therefore, when notifying the caller of a message such as the status of the user, the burden on the user (the called party) can be reduced and diversification can be achieved, thereby improving serviceability.

  In the present embodiment, a message to be transmitted is determined based on determination of whether or not a plurality of messages are similar. Accordingly, only non-redundant messages can be automatically transmitted to the mobile communication terminal 20 without requiring user selection or the like. As described above, according to the present embodiment, the message can be appropriately transmitted to the mobile communication terminal 20 without increasing the burden on the user who should input the message.

  In addition, if the message “update date and time” is used when the message to be transmitted is determined as in the present embodiment, a more newly updated message can be transmitted, and mobile communication can be performed more appropriately. A message can be transmitted to the terminal 20. In addition, as in the present embodiment, by providing priority designation for a message, when there is a message to be transmitted with priority, the message can be reliably transmitted.

  Further, if a “public restriction” corresponding to the mobile communication terminal 20 on the calling side is provided as in the present embodiment, a plurality of user status input server groups 41 to 45 having different service conditions (user public conditions) Service collaboration and appropriate user privacy protection.

  Further, if a message is transmitted by voice data to the mobile communication terminal 20 on the calling side as in the present embodiment, the user can audibly know the message of the mobile communication terminal 20 on the receiving side, and usability is improved. improves. However, conversion to voice data is not necessarily required. For example, a message may be transmitted to the mobile communication terminal 20 on the transmission side as text data, and the message may be displayed on the mobile communication terminal 20 on the transmission side.

  In the present embodiment, the example of the mobile communication terminal 20 has been described as the message transmission destination. However, the message transmission destination is not necessarily the mobile communication terminal 20, and a fixed communication terminal (for example, a fixed telephone). But you can.

  Further, in the example of the process of transmitting a message to the mobile communication terminal 20 on the calling side described with reference to FIG. 5, in S22, the request is received from the message stored in the message management database of the message accumulation unit 11. A message that is a candidate to be transmitted to the mobile communication terminal 20 on the transmission side has been acquired together with the additional information of the message. Here, the additional information of the message is used in the user authentication process of S23, and the message that should be transmitted by the authentication becomes a candidate message to be transmitted to the mobile communication terminal 20 on the transmission side.

  Therefore, it is not always necessary to obtain both the message and the additional information (simultaneously) from the database. First, only the additional information is acquired, and the user authentication of the mobile communication terminal 20 on the transmission side is performed using the additional information. It is also possible to obtain only the message (the “text message” that is the main body) that is supposed to be transmitted by this authentication from the message management database of the message accumulation unit 11 (step S23). By setting it as the above processes, the number of messages acquired from the message management database of the message accumulation unit 11 can be suppressed. Thereby, for example, when the data size of each message (the “text message” that is the main body) is large, the processing load can be reduced. On the other hand, when the data size of each message (the “text message” which is the main body thereof) is small, it is possible to reduce access to the message management database of the message accumulation unit 11 by asserting the message and the additional information at the same time. So it is efficient.
