Description

Technical Field

[0001] The present invention relates to a technique for selecting a sender number by referring to the transmission history of past SMSs and transmitting an SMS.

Background Art

[0002] In recent years, the number of companies using SMS as a sales means has been increasing. SMS has the feature that it can be transmitted if the phone number of the person to be transmitted is known, and it is very useful as a sales tool for customers who call. Also, there is a service that accepts transmission requests from multiple customers and substitutes for the transmission of SMSs. Although it costs to secure a sender number, costs can be saved by sharing the sender number among customers.

[0003] In SMS in such a form, when sending several SMSs to a certain destination user at the request of a certain transmission requester, if transmitted from a plurality of numbers, it may cause confusion or give a sense of distrust. Also, when sending SMSs transmitted at the request of a plurality of transmission requesters from the same number, it may cause confusion among the destination users. Also, there may be a case where an upper limit on the number of transmissions that can be made per day is determined for each sender number.

[0004] Regarding systems related to SMS, the following techniques are known. Patent Document 1 discloses a system in which the same terminal is used for the same destination when one transmission device transmits. Patent Document 2 discloses a system that examines the SMS message transmission record within a certain period when transmitting an SMS message and selects, from among a plurality of candidate sender phone numbers, the one with the smallest number of transmission requesters for the destination of the SMS message.

[0006] However, when there are multiple transmission requesters, no measure is taken to select the same source number for the destination user for each transmission requester. Also, when there is an upper limit on the number of transmissions that can be made per day for each source number, no measure is taken to efficiently perform SMS transmissions.

[0007] An object of the present invention is to use the same source number for the same combination of a transmission requester and a destination user when transmitting an SMS to a destination user upon a request from a certain transmission requester when there are multiple transmission requesters. Another object of the present invention is to select a source number that does not overlap with the source numbers from other transmission requesters as much as possible based on the transmission history. MEANS FOR SOLVING THE PROBLEMS

[0008] The SMS transmission system of the present invention is characterized in that there are two or more source numbers used for SMS transmission, a transmission request receiving unit that receives SMS transmission requests from two or more transmission requesters, an SMS transmission unit that transmits an SMS to a destination number, a source number selection unit that selects a source number, a transmission history holding unit that holds the transmission date and time, the identifier of the transmission requester, the source number, and the destination number as a transmission record for each SMS transmission, a transmission history search unit that searches for a transmission record transmitted to the destination number in response to an SMS transmission request from the transmission requester with reference to the transmission history holding unit, and is characterized by including a conditional source number selection unit that selects the same source number as that of the transmission record when there is a transmission record transmitted during a certain past period in the transmission history search unit.

[0009] According to this feature, it is possible to search for the transmission history based on the sender of the transmission request and the destination number, and if there is a transmission record sent during a certain period in the past, the same sender number as that transmission record can be selected.

[0010] If the same sender number is used for the same destination number as in the system described in Patent Document 1, when multiple senders use it, and when there is an upper limit on the number of sent messages for the sender number, the number of messages that can be sent will decrease. If the senders are different, by allowing different sender numbers to be used for the same destination, it is possible to prevent the number of messages that can be sent from decreasing.

[0011] The SMS transmission system of the present invention is characterized by including an unsent number selection unit that searches the transmission history storage unit when there is no transmission record sent during a certain period in the past in the transmission history search unit, and selects a sender number that has no transmission record sent to the destination number during a certain period in the past if there is such a sender number.

[0012] According to this feature, it is possible to search for the transmission history based on the sender of the transmission request and the destination number, and if there is no transmission record sent during a certain period in the past, a sender number that has no transmission record sent to the destination number during a certain period in the past can be selected if there is such a sender number. That is, the same sender number as the previous time can be used for the destination that has already been sent, and a sender number that has not been sent by other senders can be used for the destination that has not been sent.

[0013] The SMS transmission system of the present invention includes a sender number usability determination unit that determines whether a sender number can be used, and instead of the conditional sender number selection unit, when there is a transmission record sent during a certain period in the past in the transmission history search unit and the same sender number as that transmission record is determined to be usable in the sender number usability determination unit, it is characterized by including a conditional usable sender number selection unit that selects the sender number.

[0014] The source of transmission may have a daily transmission limit. When the limit is reached, SMS cannot be sent from the source number. According to this feature, it is possible to determine whether the source number is available, search for transmission records with the sender number and the destination number of the transmission request, and if there is a source number that was used for transmission records sent during a certain period in the past and is available, select it.

[0015] The SMS transmission system of the present invention In the transmission history search section, when there is no transmission record sent during a certain period in the past whose source number is the same as that of the transmission record and is determined to be available in the source number availability determination section, search the transmission history storage section, and if there is a source number that has no transmission record sent to the destination number during a certain period in the past and is determined to be available in the source number availability determination section, select it. It is characterized by comprising an unsent available number selection section.

[0016] According to this feature, if there is no source number that was used for transmission records sent during a certain period in the past and is available, it is possible to select a source number that has no transmission record sent to the destination number during a certain period in the past and is available.

[0017] The SMS transmission system of the present invention When there is no transmission record sent during a certain period in the past in the transmission history search section whose source number is the same as that of the transmission record and is determined to be available in the source number availability determination section, there is an unavailable number waiting section that waits for a maximum of a certain time, and If, before the waiting ends, there is a transmission record sent during a certain period in the past in the transmission history search section whose source number is the same as that of the transmission record and is determined to be available in the source number availability determination section, it is characterized by comprising a restored source number selection section that selects that source number.

[0018] According to this feature, if there is no available sender number among the sender numbers of the transmission records sent during a certain period in the past, wait for a maximum of a certain period of time. If, before the end of the waiting period, there is an available sender number among the sender numbers of the transmission records sent between the transmission requester and the destination number during a certain period in the past, then it can be selected.

[0019] The SMS transmission system of the present invention includes a sender number unusable reason determination unit that determines the reason for being unusable when it is determined to be unusable in the sender number usability determination unit, Instead of the unusable number waiting unit, when there is no transmission record sent during a certain period in the past in the transmission history search unit for which the same sender number as that transmission record is determined to be usable in the sender number usability determination unit, and if the reason for being unable to transmit determined by the sender number unusable reason determination unit satisfies specific conditions, it is characterized by including a specific reason waiting unit that waits for a maximum of a certain period of time.

[0020] According to this feature, when the sender number is unusable, determine the reason for being unusable, search for the transmission history with the transmission requester and the destination number, and if there is no available sender number among the sender numbers of the transmission records sent during a certain period in the past, and if the reason for being unable to transmit satisfies specific conditions, it is possible to wait for a maximum of a certain period of time.

[0021] The SMS transmission program of the present invention, is characterized in that there are two or more sender numbers used for SMS transmission, a transmission request reception process for receiving SMS transmission requests from two or more transmission requesters, an SMS transmission process for transmitting SMS to the destination number, a sender number selection process for selecting a sender number, a transmission history holding process for holding the transmission date and time, the identifier of the transmission requester, the sender number, and the destination number as the transmission record for each SMS transmission, a transmission history search process for searching for the transmission record transmitted to the destination number in the SMS transmission request from the transmission requester with reference to the transmission history holding process. In the transmission history search process, when there is a transmission record sent during a certain period in the past, a conditional transmission source number selection process is executed to select the same transmission source number as that transmission record.

[0022] According to this feature, a computer can be operated as an SMS transmission program.

Effect of the Invention

[0023] According to the present invention, when there are multiple transmission requesters, in the case of sending an SMS to a user of a certain destination upon a request from a certain transmission requester, in the case of the combination of the same transmission requester and the destination user, it is possible to use the same transmission source number, and an SMS transmission system and an SMS transmission program are provided that select a transmission source number that does not overlap with the transmission source numbers from other transmission requesters as much as possible based on the transmission history.

BEST MODE FOR CARRYING OUT THE INVENTION

[0025] Hereinafter, an example in the first embodiment of the present invention will be described. (Example: First Embodiment)

[0026] FIG. 1 is a diagram showing the configuration of the SMS transmission system 1 in the first embodiment.

[0027] The SMS transmission system 1 is connected to the user terminal 2 and the customer terminal 3 via a communication network.

[0028] The SMS transmission system 1 includes a transmission request receiving section 11, a transmission source number selection section 12, an SMS transmission section 13, a transmission history holding section 14, a transmission history search section 15, a conditional transmission source number selection section 16, and an untransmitted number selection section 17.

[0029] The communication network may be a telephone network, a dedicated line, a LAN (LOCAL AREA NETWORK), the Internet, or a combination thereof.

[0030] The processes corresponding to the respective components of the SMS transmission system 1 (transmission request receiving section 11, transmission source number selection section 12, SMS transmission section 13, transmission history holding section 14, transmission history search section 15, conditional transmission source number selection section 16, untransmitted number selection section 17) may be executed by one device or by a plurality of devices. The devices that execute the processes corresponding to the respective components may be physically separated from each other.

[0031] The transmission request receiving section 11 receives an SMS transmission request from a transmission requester.

[0032] The transmission source number selection section 12 selects a transmission source number upon receiving a request.

[0033] The SMS transmission section 13 transmits an SMS to the destination number.

[0034] The transmission history storage unit 14 stores the transmission date and time, the identifier of the transmission requester, the sender number, and the destination number as the transmission record for each SMS transmission.

[0035] The transmission history search unit 15 searches the transmission history storage unit 14 for the transmission record sent by the transmission requester to the destination number.

[0036] When there is a transmission record sent during a certain past period in the transmission history search unit 15, the conditional sender number selection unit 16 selects the same sender number as that transmission record.

[0037] When there is no transmission record sent during a certain past period in the transmission history search unit 15, the unsent number selection unit 17 searches the transmission history storage unit 14 and selects a sender number that has no transmission record sent to the destination number during the certain past period if any. (First Embodiment: SMS Transmission Based on Transmission History)

[0038] Hereinafter, an example of the process of SMS transmission based on the transmission history by the SMS transmission system 1 is shown.

[0039] The transmission request reception unit 11 receives an SMS transmission request from the transmission requester "Company A".

[0040] The sender number selection unit 12 selects the sender number "08012345678" upon receiving the request.

[0041] FIG. 2 is a diagram showing an example of the SMS transmitted by the SMS transmission unit 13.

[0042] The SMS transmission unit 13 transmits an SMS from the sender number "08012345678" to the destination number "08011111111". The SMS transmission unit 13 transmits the transmission text "Thank you for your interest in our company's telephone recording service. Smart Recording · Recording Terminal Rental Plan, Initial Fee: 2,000 yen, Basic Fee: 3,500 yen per month (Terminal X1), Additional Terminals X 2,500 yen per month".

[0043] Figure 3 is a diagram showing information recorded by the transmission history holding unit 14.

[0044] The transmission history holding unit 14 holds a transmission history for each SMS transmission, and as a transmission record, it holds the transmission date and time "2023 / 12:00:00", the name of the transmission requester "Company A", the identifier of the transmission requester "A", the transmission source number "08012345678", and the destination number "08011111111".

[0045] The transmission history search unit 15 refers to the transmission history holding unit 14 to search for a transmission record transmitted by the transmission requester "Company A" to the destination number "08011111111".

[0046] Figure 4 is a flowchart showing the process until the conditional transmission source number selection unit 16 and the untransmitted number selection unit 17 select a transmission source number.

[0047] When the conditional transmission source number selection unit 16 sends an SMS to the number "08011111111", it searches the transmission history search unit 15 for transmission records transmitted during a certain period in the past and selects the same transmission source number "08012345678" as the transmission record "2023 / 12:00:00".

[0048] When the untransmitted number selection unit 17 sends an SMS to the number "08011111111" at the request of Company B, if there is no transmission record transmitted during a certain period in the past in the transmission history search unit 15, it searches the transmission history holding unit 14 and selects the transmission source number "09022222222" that has no transmission record of transmitting to the destination number "08011111111" during a certain period in the past.

[0049] Modifying this embodiment, the transmission source number selection unit 12 may select the transmission source number of the last transmitted transmission record when the conditional transmission source number selection unit 16 and the untransmitted number selection unit 17 cannot select a transmission source number.

[0050] Alternatively, the present embodiment may be modified to examine the transmission records for the entire period instead of a certain past period. Also, in that case, it may be decided not to hold the transmission date and time in the transmission history holding unit 14.

[0051] Alternatively, when the present embodiment is modified and there is an identifier for each transmission source number, the transmission history holding unit 14 may hold the identifier instead of holding the transmission source number. For example, when the transmission terminal using the transmission source number is determined for each transmission source number, the identifier of the transmission terminal may be held instead of the transmission source number.

[0052] Alternatively, when the present embodiment is modified, if there are multiple corresponding transmission source numbers and the conditional transmission source number selection unit 16 and the untransmitted number selection unit 17 are unable to select a transmission source number, the transmission source number with the fewest transmissions during a certain past period may be selected by the transmission source number selection unit 12.

[0053] Alternatively, when the present embodiment is modified, if there are multiple corresponding transmission source numbers and the conditional transmission source number selection unit 16 and the untransmitted number selection unit 17 are unable to select a transmission source number, the transmission source number with a transmission count equal to or less than a certain number during a certain past period may be selected by the transmission source number selection unit 12.

[0054] Hereinafter, an example in the second embodiment of the present invention will be described. (Example: Second Embodiment)

[0055] FIG. 5 is a diagram showing the configuration of the SMS transmission system 1 in the second embodiment.

[0056] The SMS transmission system 1 includes a transmission request receiving unit 11, a transmission source number selection unit 12, an SMS transmission unit 13, a transmission history holding unit 14, a transmission history search unit 15, a transmission source number usability determination unit 111, a conditional usable number selection unit 112, an untransmitted usable number selection unit 113, an unusable number waiting unit 114, a recovery transmission source number selection unit 115, a transmission source number unusability reason determination unit 116, and a specific reason waiting unit 117.

[0057] The communication network is a telephone network, a dedicated line, a LAN (LOCAL AREA NETWORK), the Internet, etc., or a combination thereof.

[0058] The processing corresponding to each component of the SMS transmission system 1 (transmission request receiving unit 11, transmission source number selection unit 12, SMS transmission unit 13, transmission history holding unit 14, transmission history search unit 15, transmission source number usability determination unit 111, conditional usable number selection unit 112, unused usable number selection unit 113, unusable number waiting unit 114, recovery transmission source number selection unit 115, transmission source number unusability cause determination unit 116, specific reason waiting unit 117) may be executed by one device or by a plurality of devices. The devices that execute the processing corresponding to each component may be physically located at separate positions.

[0059] The transmission source number usability determination unit 111 determines whether the transmission source number is usable.

[0060] The conditional usable number selection unit 112 selects the transmission source number when the selected transmission source telephone number is determined to be usable by the transmission source number usability determination unit 111, in place of the conditional transmission source number selection unit 16.

[0061] The unused usable number selection unit 113 searches the transmission history holding unit 14 for a transmission source number that has no transmission record sent to the destination number during a certain period in the past and for which the same transmission source number as that transmission record is determined to be usable by the transmission source number usability determination unit 111, and selects that number if there is such a transmission source number.

[0062] The unusable number waiting unit 114 waits for a maximum of a certain time when there is no transmission source number that is the same as the transmission record and is usable by the usable number selection unit 112 in the transmission records sent during a certain period in the past in the transmission history search unit 15.

[0063] The restoration transmission source number selection unit 115 selects the transmission source number if there is a transmission record sent during a certain period in the past in the transmission history search unit 15 and the transmission record with the same transmission source number is determined to be available in the transmission source number availability determination unit 111.

[0064] The transmission source number unavailability reason determination unit 116 determines the reason for unavailability when it is determined to be unavailable in the transmission source number availability determination unit 111.

[0065] Instead of the unavailable number waiting unit 114, the specific reason waiting unit 117 waits for a maximum of a certain time when, in the transmission records sent during a certain period in the past in the transmission history search unit 15, there is no transmission record with the same transmission source number that is determined to be available in the transmission source number availability determination unit 111, and when the reason for transmission unavailability determined by the transmission source number unavailability reason determination unit 116 satisfies specific conditions. (Second Embodiment: SMS Transmission for Determining the Availability of a Transmission Source Number)

[0066] The transmission source number availability determination unit 111 determines whether the transmission source number "08012345678" is available and holds "available".

[0067] Instead of the conditional transmission source number selection unit 16, the conditional available number selection unit 112 selects the transmission source number "08012345678" when referring to the transmission source number unavailability reason determination unit 116 and it is determined to be "available" for the transmission source telephone number "08012345678".

[0068] Figure 6 is a flowchart showing the selection process performed by the untransmitted available number selection unit 113.

[0069] The non-transmitted available number selection unit 113, instead of the non-transmitted number selection unit 17, searches the transmission history holding unit 14 for a transmission record sent during a certain period in the past by searching with the transmission history search unit 15. When the same transmission source number "08012345678" as that transmission record is "unusable" in the transmission source number usability determination unit 111, it selects a transmission source number that has no transmission record sent to the destination number "08011111111" during a certain period in the past and that is determined as "usable" in the transmission source number usability determination unit 111, i.e., the transmission source number "08022222222".

[0070] When the conditional available number selection unit 112 and the non-transmitted available number selection unit 113 cannot select a transmission source number, the transmission source number selection unit 12 may select, among the available terminals, the transmission source number of the last transmission record of the transmission record between the transmission requester and the destination number.

[0071] When a plurality of transmission source numbers are found by the conditional available number selection unit 112, the transmission source number selection unit 12 may select, among the available terminals, the transmission source number with the largest number of transmissions within a certain period in the past of the transmission record between the transmission requester and the destination number. (Second Embodiment: When the number is unusable)

[0072] The unusable number waiting unit 114 searches the transmission history search unit 15 for a transmission record sent during a certain period in the past. When the same transmission source number "08012345678" as that transmission record is "unusable" in the transmission source number usability determination unit 111, it waits for a maximum of a certain time.

[0073] The restored transmission source number selection unit 115 searches the transmission history search unit 15 for a transmission record sent during a certain period in the past until the waiting ends. If there exists a transmission record in which the same transmission source number "08022222222" as that transmission record is determined as "usable" in the transmission source number usability determination unit 111, it selects that transmission source number "08022222222".

[0074] FIG. 7 is a diagram showing a determination result displayed by the transmission source number unusable reason determination unit 116.

[0075] When the transmission source number unusable reason determination unit 116 determines that the transmission source number is "unusable" in the transmission source number usability determination unit 111, it determines the unusable reasons "during terminal restart" and "waiting until the next day because the transmission limit has been reached".

[0076] FIG. 8 is a flowchart showing the response of the specific reason waiting unit 117.

[0077] When the specific reason waiting unit 117 searches in the transmission history search unit 15 and finds a transmission record sent during a certain period in the past, and the same transmission source number "08012345678" as that transmission record is "unusable" in the transmission source number usability determination unit 111, if the reason for transmission unavailability determined by the transmission source number unusable reason determination unit 116 is "during terminal restart", it waits for a certain period of time. If the reason is "waiting until the next day because the transmission limit has been reached", without waiting, the non-transmitted usable number selection unit 113 searches the transmission history holding unit 14 to find a transmission source number that has no transmission record sent to the destination number "08011111111" during a certain period in the past, and selects a transmission source number "08022222222" that is determined to be "usable" in the transmission source number usability determination unit 111.

Industrial Applicability

[0078] The present invention enables the use of the same transmission source number in the case of a combination of the same transmission requester and the destination user when sending an SMS to a user of a certain destination at the request of a certain transmission requester when there are multiple transmission requesters. It is an SMS transmission system and an SMS transmission program that selects a transmission source number that does not overlap with the transmission source numbers from other transmission requesters as much as possible based on the transmission history. It can be considered for use in an office that provides a proxy system for email magazine distribution.
