  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings referred to in the following description, the same parts as those in the other drawings are denoted by the same reference numerals.

(overall structure)
FIG. 1 is a block diagram showing a mobile phone network according to an embodiment of the present invention. In FIG. 1, a mobile phone network 1 is an example of a mobile phone network, and can provide various services to users. One of these services is disaster voice delivery service. The disaster voice delivery service is a service using packet communication and SMS. In this service, when a voice message is recorded by designating a mobile phone number on the receiver side from the mobile terminal 2 on the sender side, the recorded message is uploaded by packet communication. Then, the fact that the voice message from the sender side has arrived is transmitted to the portable terminal 3 on the receiver side by an SMS message. In this SMS message, a URL or the like is displayed, and when the recipient clicks it, the recorded message can be downloaded and the recorded message can be heard. Hereinafter, details of the disaster voice delivery service provided by the mobile phone network 1 will be described.
2 to 4 are communication sequence diagrams for explaining a disaster voice delivery service provided by the mobile phone network 1 according to the embodiment of the present invention. The cellular phone network 1 is compatible with Internet services, and nodes for providing various services to users are prepared on the cellular phone network 1.

First, the IP service control device 11 is a subscriber database related to the control of the Internet service, particularly related to the management of the user profile of the mobile phone network 1. The voice storage device 12 is a device that stores a voice message file. The message transmission device 13 functions as a SMSC (Short Message Service Center). The voice message delivery control device 14 is a node that implements a service that provides various added values. The voice message delivery control device 14 is a system corresponding to the voice message delivery control device, and includes a computer on which a voice message delivery control program operates. Various processes as described later can be executed as processes based on the voice message delivery control program. Voice message delivery control is realized by these processes. In this example, a voice message delivery control system is realized by the voice storage device 12, the message transmission device 13, and the voice message delivery control device. In FIG. 2, the voice storage device 12 and the voice message delivery control device 14 are described as logically separate devices, but they may be physically realized as the same device.
FIG. 5 is a functional block diagram of the voice message delivery control device 14. The voice message delivery control device 14 includes functions of an inquiry unit 51, an estimation unit 52, a notification generation unit 53, and a transmission unit 54. These functions will be described later.

  Next, the processing procedure of the disaster voice delivery service realized by these systems will be described with reference to FIGS. First, the process until the recording message is stored will be described with reference to FIG. A sender who wants to send a voice message to the other party's mobile terminal 3 operates his / her own mobile terminal 2 to input the destination mobile phone number (S201). A prior inquiry request for sending a voice message is made (S202). This request is delivered to the voice message delivery control device 14, and the voice message delivery control device 14 requests the IP service control device 11 for the user profiles of the sender and the receiver (S203, S205). In response to this, the IP service control device 11 transmits the user profiles of the sender and receiver to the voice message delivery control device 14 (S204, S206). Then, the voice message delivery control device 14 determines, based on this user profile, whether or not the sender and the receiver are users who can provide the disaster voice delivery service (S207). As a result, when it is confirmed that the sender and the receiver can use the disaster voice delivery service, the voice message delivery control device 14 saves a prior upload request, which is a notification to upload a voice message, as a voice. It performs with respect to the apparatus 12 (S208). This is a request for inquiring the audio storage device 12 about the storage location of the audio file, and is performed by the inquiry unit 51. In response to this, the voice storage device 12 returns a pre-upload response to the voice message delivery control device 14 (S209). This transmits an upload temporary URL for designating a storage location of the audio file.

  Next, the voice message delivery control device 14 is expected to take from the storage of the voice message by the voice storage device 12 to the transmission of the SMS message that enables the voice message to be downloaded by the calculation unit 51. The elapsed time is calculated (that is, the expected time level is calculated) (S210). This is realized by the estimation unit 52. Details of this processing will be described later.

  Next, the voice message delivery control device 14 sends a pre-inquiry response to the sender's mobile terminal 2 as an SMS message by the sending unit 54 (S211). In this message, the above-mentioned temporary URL for uploading that enables uploading of the voice message is displayed, and the sender can upload the voice message. Also, the time that is expected to be taken from the time when the voice message obtained by the above-described calculation of the expected time level (S210) is saved by the voice storage device 12 until the SMS message that enables downloading of the voice message is transmitted. Is notified to the sender by this SMS message in three stages of levels 1 to 3.

  Upon receiving this SMS message, the sender records a voice message (S212). Then, when an upload request for uploading the message file of the voice message is made to the voice storage device 12 (S213), the voice storage device 12 returns an upload response to the sender's portable terminal 2 (S214), and voice communication is performed by packet communication. The message file of the message is transmitted, and the message file is accumulated and stored (S215).

(Receiver notification process)
Next, a process for notifying the recipient's mobile terminal 3 of the recording of the voice message will be described with reference to FIG. As described above, when the message file of the voice message is stored in the voice storage device 12, the voice message delivery control device 14 requests the message transmission device 13 to transmit the SMS message to the mobile terminal 3 of the recipient. (S301). In response to this, the message transmission device 13 transmits a notification that a voice message has arrived from the sender to the receiver's mobile terminal 3 by an SMS message (S302). The SMS message displays a URL for downloading a recorded message file, and the recipient can download the message file and listen to the voice message. When this SMS message reaches the recipient's mobile terminal 3, the message transmission device 13 notifies the voice message delivery control device 14 of the delivery of the SMS message (S303). Thereby, the voice message delivery control apparatus 14 can know that the SMS message for notifying that the voice message has arrived has reached the recipient's mobile terminal 3.

(Voice message download process)
Next, voice message download processing will be described with reference to FIG. After the SMS message reaches the recipient's portable terminal 3, when the recipient clicks the URL of the SMS message on the portable terminal 3 (S401), a message download screen request is sent from the portable terminal 3 to the voice message delivery control device 14 (S402). In response, the voice message delivery control device 14 sends a message download screen response to the portable terminal 3 (S403). As a result, a message download screen is displayed on the display of the mobile terminal 3. Next, the voice message delivery control device 14 makes a reading reservation for the message file corresponding to the voice storage device 12 (S404).

  Thereafter, when the recipient of the SMS message clicks the message download screen on the portable terminal 3 (S405), a message download request is transmitted from the portable terminal 3 to the voice storage device 12 (S406), and a message download response is sent from the voice storage device 12. It is made to the portable terminal 3 (S407). Thereby, the message file of the corresponding voice message is downloaded by packet communication, and the receiver can listen to the voice message on the portable terminal 3. When the downloading of the message file is completed, a file read completion notification is transmitted from the voice storage device 12 to the voice message delivery control device 14 (S408). When the message download is completed, a file read completion notification may be transmitted to the message sender and the delivery may be completed, or the delivery may be completed when the recording notification SMS message arrives.

(Calculation of expected time level)
Next, the process of the expected time level calculation (S210) performed by the calculation unit 51 described above will be described with reference to FIG.
First, in order to obtain an estimate of the expected time level of how long it takes for the SMS message notifying the presence of the voice message to reach the recipient, the recipient who is the destination of the voice message in the cellular phone network 3 In other words, it is indispensable to make a determination in the unit of the recipient, which is the smallest unit, and to consider the network status for each region. Then, when considering the network status of each receiver area, it is necessary to consider the network status bias for each area. There is also a need to promptly collect necessary information in order to promptly inform the sender.

Therefore, as means for obtaining such an estimate of the expected time level, the following three can be considered as information that can be obtained by the voice message delivery control device 14.
The first is means for obtaining a rough estimate of the expected time level for each voice message recipient. Since this means knows the status of the network in which the recipient of the voice message is located, it can take into account the network status bias for each region. On the other hand, it takes time to collect necessary information.
The second is a means for obtaining a rough estimate of the expected time level for each mobile phone number band. This method may not be able to take into account the bias of the network situation by region, and although the information collection time is shorter than the method of obtaining an estimate of the expected time level for each voice message recipient, how to separate number bands Depending on the case, the result will not change much.

The third is a means for obtaining a rough estimate of the expected time level in units of the entire cellular phone network 1 system. Although this method cannot take into account the network status bias for each region, it collects information relatively early compared to the first and second methods, and obtains an estimate of the expected time level at an early stage. be able to.
In this example, the first means described above can be used in consideration of the deviation of the network status in each region. However, if sufficient sample data for implementing the first means cannot be expected, the above-mentioned third means can be used to obtain an estimate of the expected time level at an early stage.

(Processing executed by the voice message delivery control device)
Below, the concrete process which the voice message delivery control apparatus 14 performs is demonstrated with reference to the flowchart of FIG. 6, FIG.

  In FIG. 6, the voice message delivery control device 14 is recording and storing a waiting service, that is, the voice message described above, with respect to the portable terminal 3 of the person who should be a recipient of the corresponding voice message. It is determined whether there is a service in which the SMS message indicating that the voice message has arrived has not been transmitted to the portable terminal 3 of the recipient (step S1). This step S1 corresponds to a first determination unit. This can be determined by the presence / absence of a service for which the above-described SMS message delivery notification (S303) has not yet been transmitted. If this waiting service exists (step S1: Yes), the waiting service with the earliest storage time of the voice message is associated with the portable terminal 3 of the person who should be the recipient of the corresponding voice message. It is determined whether or not the user has been waiting for a predetermined time t1 or more (step S2). This step S2 corresponds to a second determination unit. That is, it is determined whether or not the waiting time of the SMS message delivery notification (S303) that has not been transmitted to the portable terminal 3 of the person who should be the recipient is the longest waiting time is t1 hours or more. If the waiting service with the earliest storage time of the voice message has been waiting for a predetermined time t1 or more (step S2: Yes), it is determined that the network status of the receiver's mobile terminal 3 is the worst. Then, it is determined as level 3 (step S4). If the waiting service with the earliest storage time of the voice message has not been waiting for t1 hours or more (step S2: No), the network status in which the receiver's mobile terminal 3 is located is better than level 3 (Step S5).

On the other hand, when there is no waiting service (step S1: No), the SMS message indicating that the voice message has arrived has successfully reached the portable terminal 3 of the person who should be the corresponding recipient. It is determined whether or not the latest one has been within a predetermined time t2 (step S3). This step S3 corresponds to a third determination unit. That is, it is determined whether or not the elapsed time from the time when the SMS message delivery notification (S303) was received most recently by the portable terminal 3 of the person who should be the corresponding recipient exceeds t2 hours. If the latest successful reception is within t2 hours (step S3: Yes), the network status of the receiver's mobile terminal 3 is determined to be level 1 better than level 2 ( Step S5). The determination so far is a means for obtaining a rough estimate of the expected time level for each voice message recipient.
On the other hand, when the latest successful record is not within t2 hours (step S3: No), the estimated time level is calculated in units of the entire system (step S7). Step S7 corresponds to a fourth determination unit.

(Calculation of expected time level for the entire system)
FIG. 7 is a flowchart showing a subroutine of step S7. That is, if it is within one hour from the start of the disaster voice delivery service (step S11: Yes), it is assumed that there is no information that can be used to obtain the estimated time level by the process of FIG. 6 (step S12). finish.

  When one hour or more has elapsed from the start of the disaster voice delivery service (step S11: No), an estimate of the expected time level is acquired as follows. First, for all users who can be recipients of the SMS message delivery notification (S303), the voice message has arrived among all the message files for which the upload response (S214) has been received in the disaster voice delivery service. The SMS message is actually transmitted to the recipient's mobile terminal 3 (S302), and the ratio of the service within a predetermined time is obtained as a “distribution rate”.

  When the distribution rate is less than a% (step S13: Yes), it is determined that the voice message is level 3 which is most difficult to reach the recipient (step S14). When the distribution rate is a% or more (step S13: No), it is determined whether the distribution rate is a% or more and less than b% (a <b) (step S15). When the distribution rate is a% or more and less than b% (step S15: Yes), it is determined that the voice message is level 2 that is easy to reach the recipient to some extent (step S16). If the distribution rate is not a% or more and less than b% (step S15: No), it is determined that the voice message is level 1 that is most likely to reach the recipient (step S17).

  As described above, it is determined whether the level is changed from level 1 to level 3 in the process of FIG. 5 or the process of FIG. 6, and a message corresponding to the result is notified by the prior inquiry response (S211). For example, if it is level 3, a message saying that “it will take a considerable amount of time for the voice message to reach the recipient” and if it is level 2, “a certain amount of time is required for the voice message to reach the recipient. For example, a message that “it is expected to be required” and a message that “it is expected that it will not take too much time for the voice message to reach the recipient” are transmitted at level 1. These messages can be appropriately selected. In this example, three levels of determination from level 1 to level 3 are performed, but a finer standard of 4 levels or more may be notified.

As described above, the estimated time until the SMS message indicating that the voice message has arrived at the destination after the voice message is stored is shown in FIG. By making the determination, it is possible to make a more accurate determination in consideration of the deviation of the network status for each region.
In addition, when it is not possible to make a judgment in units of voice message recipients, it is possible to promptly collect information necessary for judgment by judging the whole system of the mobile phone network 1 as shown in FIG. it can.

(Application examples)
Incidentally, it goes without saying that the present invention is not limited to the above description. First, in the subroutine of step S7 described with reference to FIG. 7, the expected time level may be calculated by the traffic of the exchange or the SMSC. In this case, for example, as shown in FIG. 8, when the disaster voice delivery service is started within one hour (step S11: Yes), traffic of the exchange or the SMSC is acquired (step S12a), and the expected time level is set. It may be calculated (step S12b). When the predicted time level is calculated, the level may be determined and notified in, for example, three stages according to the traffic value. In FIG. 8, the contents of the other processes are the same as those described with reference to FIG.

7 and 8, the processing is performed based on the elapsed time from the start of the disaster voice delivery service (in this example, within one hour), but the number of sample data is used instead of the elapsed time. The process may be performed based on whether or not is equal to or greater than a certain value.
Further, the present invention can be applied even when the mobile phone carrier is different between the sender and the receiver of the voice message.

  First, when the voice message recorder is the own network (communication network by the own mobile phone carrier), as shown in FIG. 9, the recorder 21 of the own network performs voice message recording 22, and the other network (another mobile phone). The calculation 24 of the estimated time until the notification of the presence of the voice message reaches the receiver 23 of the telephone network) can be performed as described above. The calculation of the estimated time until the notification addressed to the other mobile phone carrier arrives can also be calculated from the notification means of some message including the SMS message, the arrival result of the voice message, and the like. The recipient 23 of the other network can be notified that the voice message has arrived by various notification means 25 as well as the SMS message. For example, it is possible to notify that a voice message has arrived using HTTP (HyperText Transfer Protocol), e-mail, or the like. Upon receiving this notification, the recipient 23 of the other network can perform acquisition 26 of the voice message.

  Further, as shown in FIG. 10, even when the voice message recorder is a recorder 31 of another network and the receiver is a receiver 32 of the own network, the service center that processes the disaster voice delivery service is provided. If it exists in the local network, it is possible to calculate the estimated time until the notification of the presence of the voice message in the other network arrives. The notification result 27 and the voice message acquisition result notification 27 are performed. Note that such notification is not necessary when the above-mentioned service center exists in another network due to the configuration of the communication network.

  In the above example, the notification to the user is performed by the SMS message, but it may be performed by e-mail instead. That is, as shown in FIG. 11, a voice message recorder 41 transmits a message by a mechanism such as SMTP (Simple Mail Transfer Protocol) (reference numeral 42 in FIG. 11) to record the voice message. Calculation of the estimated time until the notification of the presence of the voice message arrives (reference numeral 43 in FIG. 11) can be performed in the same manner as in the above example using the SMS message. However, the difference is that the data for calculation relates to a notification means other than the SMS message. In this example, the notification means 44 for notifying that the voice message has arrived from the recording person 41 is performed by transmitting an e-mail to the receiving person 45. Thereby, the receiver 45 acquires the voice message 46 by a mechanism such as POP (Post Office Protocol). The calculation 43 of the above-mentioned time standard when the provider is different between the recording person 41 and the receiving person 45 can be performed in the same manner as described with reference to FIGS.
