A creation means for creating an incoming call notification message by integrating the incoming call history stored in the storage means in association with the identification information added to the text message received by the reception means; and the creation means And a second transmitting means for transmitting the received notification message to the receiving terminal.

  The notification method according to the present invention includes an incoming call history including outgoing terminal information for specifying the outgoing terminal and incoming terminal information for specifying the incoming terminal when the incoming terminal is unable to receive a call from the outgoing terminal to the incoming terminal. A storage step for storing identification information for identifying an incoming call history, a first transmission step for transmitting the identification information to the calling terminal, and a receiving step for receiving a character message to which the identification information is added from the calling terminal; A creation step of creating an incoming notification message by integrating the identification information added to the text message received in the reception step and the incoming history associated with the storage step in the storage step; and the incoming call generated in the integration step A second transmission step of transmitting the notification message to the receiving terminal.

  The message server of the present invention includes an incoming call history that includes outgoing terminal information for specifying the outgoing terminal and incoming terminal information for specifying the incoming terminal when the incoming terminal is unable to receive a call from the outgoing terminal to the incoming terminal. And a receiving server configured to be able to communicate with a registration server storing identification information for identifying an incoming call history, and to receive a character message transmitted from a calling terminal and to which identification information is added. The incoming call history stored in association with the identification information added to the text message is acquired from the registration server, and the received call history is integrated with the text message received by the receiving means to create an incoming call notification message addressed to the receiving terminal. And a creating means.

  In the present invention, when a call request is made from the calling terminal to the receiving terminal, if the receiving terminal is unable to receive a call, an incoming call history including the calling terminal information and the receiving terminal information is generated. The incoming call history and paid-out identification information are stored in association with each other. Subsequently, the identification information is transmitted to the transmitting terminal. For example, if the caller inputs and returns a message to the callee in response to receiving the identification information, the message to the callee can be easily transmitted to the notification system. At the same time, identification information that can identify the incoming call history is transmitted to the notification system. In the present notification system, the incoming call history associated with the identification information added to the received text message is integrated into the text message to create an incoming call notification message, which is transmitted to the receiving terminal. As a result, an incoming call notification message in which the incoming call history and the message from the caller to the callee are integrated can be transmitted to the receiving terminal. Therefore, the called party can know the fact that there is an incoming call and can easily know the message from the calling party in association with the incoming call.

  The notification system of the present invention preferably includes a control unit that controls at least a part of radio resources between the transmission terminal and the notification system, and the control unit wirelessly responds to a transmission request output from the transmission terminal.

  Normally, the radio resource established in response to the call request is released when it is detected that the receiving terminal cannot receive the call. On the other hand, in the present invention, when it is found that the receiving terminal cannot receive the call, the first transmission means transmits the text message to the calling terminal using the wireless resource without releasing the wireless resource. Later, radio resources are released. Therefore, it is possible to omit the procedure for establishing the radio resource necessary for transmitting the text message.

  The communication terminal of the present invention is configured to be communicable with the notification system, receiving means for receiving the identification information transmitted by the first transmission means of the communication system, and a character message to which the received identification information is added. It is characterized by comprising generating means for generating and transmitting means for transmitting the generated character message to the communication system. Thereby, the communication terminal of this invention can transmit the character message to which the identification number was added easily to a notification system.

  According to the present invention, when a receiving terminal cannot receive a message, a message can be easily notified from the caller to the callee. The called party can easily know the message from the calling party in association with the incoming call history, and the convenience is improved, for example, leading to an appropriate response thereafter.

  Hereinafter, embodiments of a notification system according to the present invention will be described in detail with reference to the drawings.

  First, an image of a service provided by the notification system 1 according to the present embodiment will be described with reference to FIG. First, the caller (Mr. A) calls the caller (Mr. B). That is, a call request from the calling terminal A to the receiving terminal B is made (step S1). The transmitting terminal (communication terminal) A and the receiving terminal B are mobile communication terminals such as a mobile phone, a PHS (Personal Handyphone System), or a PDA (Personal Digital Assistant). At this time, it is assumed that the incoming terminal B cannot be received because it is located outside the service area or is powered off. Then, in the communication network, it is determined that the receiving terminal B is in an out-of-service state (cannot receive a call), and a guidance such as “cannot answer the call” is sent from the communication network to the calling terminal A ( Step S2).

  On the other hand, in the notification system 1, when it is detected that the receiving terminal B cannot receive the call in response to the call request from the calling terminal A, a short message is transmitted from the notification system 1 to the calling terminal A (step S3). . This short message prompts the caller to send a short message to the callee. For example, “090-BBBB-BBBB cannot answer the call. If you want to notify the message, reply to this short message. Please read ".

  When the caller (Mr. A) knows from the guidance that the receiving terminal B is unable to receive the call and hangs up the call, the caller (Mr. A) receives the short message transmitted from the notification system 1. The caller (Mr. A) sends a short message from the calling terminal A to the notification system 1 in a form of replying to the short message (step S4). In this short message, you can enter a phone requirement such as “Tomorrow's drinking party. Please call back.”

  When the notification system 1 receives the short message returned from the calling terminal A, the notification system 1 integrates the previously generated incoming history and the received short message to create an incoming notification message (step S5). The incoming call history is information indicating the date and time when there is an incoming call from the calling terminal A to the receiving terminal B.

  The created incoming notification message is transmitted to the incoming terminal B (step S6). As a result, when the receiving terminal B returns to the service area, it receives a short message such as “09/26 16:19 090-AAA-AAA-A tomorrow's drinking party. Please call back.” Therefore, the callee can know that there is an incoming call from Mr. A (the caller) and the purpose of the call at the same time when the callee returns to the area.

  Next, the notification system 1 for realizing such a service will be described. First, the configuration of the notification system 1 will be described with reference to FIG. The notification system 1 according to the present embodiment is a system associated with a mobile communication network to which the transmission terminal A and the reception terminal B belong.

  The notification system 1 includes an SMSC 10, an SMS-IWMSC / SMS-GMSC (Short Message Service-Inter Working. Mobile Switching Center / Short Message Service-Gateway Mobile Switching Center) 11, an MSC / VLR (Mobile Switching Center / Visited Location Register) 20, HLR (Home Location Register; registration server) 30, and MSC / VLR 40 on the receiving terminal B side. These SMSC 10, SMS-IWMSC / SMS-GMSC 11, MSC / VLR 20, HLR 30, and MSC / VLR 40 have functions similar to those in the existing mobile communication network. It is configured to be able to use telephone calls and short message services. The short message service is, for example, a service that specifies a transmitting terminal and a receiving terminal using a telephone number, and enables information including a text message to be transmitted and received between the transmitting terminal and the receiving terminal.

  The SMSC 10 is a device that stores and distributes short messages. The MSC / VLR 20 is an exchange that communicates with the calling terminal A via the base station to which the calling terminal A belongs. The HLR 30 is a device that manages information (subscriber information) of the transmitting terminal A and the receiving terminal B. The HLR 30 stores information indicating the location of each terminal as subscriber information. The MSC / VLR 40 is an exchange that communicates with the terminating terminal B via the base station to which the terminating terminal B belongs. The SMS-IWMSC / SMS-GMSC 11 is a device for connecting the SMSC 10 and the MSC / VLR 20, 40 when delivering a short message.

  Hereinafter, functional components in the notification system 1 of each of these devices will be mainly described in detail.

  First, the SMSC 10 will be described. The SMSC 10 includes a message reception unit 12, an identification number determination unit 13, and a message creation unit 14.

  The message receiving unit 12 inputs and receives a short message transmitted from the calling terminal A from the SMS-IWMSC / SMS-GMSC 11. The message reception unit 12 outputs the received short message to the identification number determination unit 13.

  The identification number determination unit 13 determines whether an identification number is included in the short message output from the message reception unit 12. When the identification number determination unit 13 determines that the identification number is not included in the short message, the identification number determination unit 13 outputs the short message to the SMS-IWMSC / SMS-GMSC 11. In this case, the short message is transmitted as it is to the destination communication terminal. If the identification number determination unit 13 determines that the short message includes the identification number, the identification number determination unit 13 outputs the short message to the message creation unit 14. Details of the message creation unit 14 will be described later.

  Next, the MSC / VLR 20 will be described. The MSC / VLR 20 includes a call request receiving unit 21, a message creating unit 22, a message transmitting unit (first transmitting unit) 23, a radio resource control unit (control unit) 24, and a message receiving unit (receiving unit) 25.

  The call request receiving unit 21 receives a call request for a voice call from the calling terminal A to the receiving terminal B. The transmission request includes transmission terminal information for identifying the transmission terminal A and reception terminal information for identifying the reception terminal B. The outgoing terminal information and the incoming terminal information are, for example, telephone numbers, the outgoing terminal information is “090-AAAAA-AAAA”, and the incoming terminal information is “090-BBBB-BBBB”. When the transmission request receiving unit 21 receives the transmission request, the transmission request receiving unit 21 outputs the transmission terminal information and the reception terminal information to the HLR 30.

  The message creation unit 22 inputs a message creation instruction from the HLR 30 together with the identification number. The identification number is a number associated with the incoming call history created in the HLR 30, and is a number that identifies the incoming call history. The message creation instruction includes calling terminal information, receiving terminal information, and presence information of the receiving terminal. The message creation unit 22 creates a short message addressed to the calling terminal A using the calling terminal information.

  The text of the short message includes information based on the presence information of the receiving terminal and a message that prompts the recipient to transmit the short message. An identification number is added to the header of the short message. The message creation unit 22 sets incoming terminal information (telephone number) as the sender of the short message. For example, a short message is “Sender: 090-BBBB-BBBB, Body: Since we are in a meeting, we will contact you later, so please reply with a message”. Then, the message creation unit 22 outputs the created short message to the message transmission unit 23.

  The message transmission unit 23 transmits the short message addressed to the transmission terminal A input from the message creation unit 22 to the transmission terminal A.

  The radio resource control unit 24 controls radio resources between the calling terminal A and the MSC / VLR 20. When the transmission request receiving unit 21 receives a transmission request output from the transmission terminal A, the wireless resource control unit 24 establishes a wireless resource with the transmission terminal A. The radio resource control unit 24 releases the radio resource when the message transmitting unit 23 transmits a short message to which the information indicating the identification number is added to the transmitting terminal A when the receiving terminal B cannot make a call in the out-of-service state. To do.

  The message receiving unit 25 receives the short message transmitted from the calling terminal A and outputs it to the SMS-IWMSC / SMS-GMSC11.

  Next, the HLR 30 will be described. The HLR 30 includes a recipient information reading unit 31, an incoming call history holding unit 32, a message instruction unit 33, and a presence information holding unit 34.

  The callee information reading unit 31 inputs the call request output from the call request receiving unit 21 of the MSC / VLR 20, and reads the callee information from a subscriber information database registered in advance. Then, the HLR 30 specifies the MSC / VLR 40 of the receiving terminal B, and transmits a signal to the MSC / VLR 40 requesting the routing information to be paid out together with the receiving terminal information.

  In response to this request signal, a response signal is returned from the MSC / VLR 40 to the HLR 30. When the receiving terminal B is out of service, a response indicating that the receiving terminal B is not responding is transmitted from the MSC / VLR 40 to the HLR 30. When receiving the response that the receiving terminal B is not responding, the called party information reading unit 31 pays out an identification number in association with the transmitting terminal information and the receiving terminal information included in the transmission request. Then, together with the transmitting terminal information and the receiving terminal information, the paid identification number is output to the incoming call history holding unit 32 and the message instruction unit 33, respectively.

  When the receiving terminal information and the receiving terminal information are output from the callee information reading unit 31, the receiving history holding unit 32 receives the calling terminal information and the receiving terminal information, and information indicating the date and time when the call request is made, as an incoming call history. Associate and store. The incoming call history holding unit 32 stores the identification number output from the callee information reading unit 31 in association with the incoming call history in association with the incoming call history.

  When the calling terminal information and the receiving terminal information are output together with the identification number from the called party information reading unit 31, the message instruction unit 33 includes the calling terminal information, the receiving terminal information, and the identification number, and instructs the creation of a short message. A signal to the effect is output to the MSC / VLR 20. The message instructing unit 33 adds the presence information stored in the presence information holding unit 34 and associated with the receiving terminal information to the signal for instructing the creation of the short message, and outputs it to the MSC / VLR 20.

  The presence information holding unit 34 stores information (telephone number) of each terminal and presence information of the user of the terminal in association with each other. Presence information is information indicating the status of a user during a meeting, moving, etc., and also indicates the reason for turning off the power, the cause of being out of service area, and the like. This presence information can be registered in advance by a user using a terminal using existing technology.

  Finally, the MSC / VLR 40 will be described. The MSC / VLR 40 includes a paging processing unit 41 and a message transmission unit (second transmission unit) 42.

  The paging processing unit 41 inputs a signal requesting to pay out routing information transmitted from the HLR 30 and performs paging processing. That is, the paging processing unit 41 establishes radio resources with the receiving terminal B and performs incoming call processing. When the receiving terminal B is out of range, it is possible to detect that the receiving terminal B is out of range because there is no response to the paging process. If the response to the paging process is no response, the MSC / VLR 40 returns a response to that effect to the HLR 30.

  The message transmitting unit 42 transmits the short message addressed to the receiving terminal B input from the SMS-IWMSC / SMS-GMSC 11 to the receiving terminal B.

  Subsequently, the message creation unit 14 of the SMSC 10 will be described. The message creation unit 14 inputs a short message from the identification number determination unit 13. As described above, this short message is a short message transmitted from the calling terminal A, and includes a message from the caller to the callee, an identification number, calling terminal information, and receiving terminal information.

  The message creation unit 14 extracts the incoming call history associated with the identification number included in the short message. Then, the message creation unit 14 creates an incoming call notification message by integrating the extracted incoming call history and the message from the caller to the callee included in the input short message. The caller of this incoming call notification message is set to the calling terminal A.

  The body of the incoming call notification message includes information indicating the date and time included in the incoming call history, transmission terminal information, and a message from the caller to the callee included in the input short message. For example, the text of a short message such as “09/26 16:19 090-AAA-AAAA is a tomorrow's drinking party. Please call back” is created. The message creation unit 14 outputs the created incoming notification message to the SMS-IWMSC / SMS-GMSC 11. As a result, the incoming notification message is output to the message transmission unit 42 of the MSC / VLR 40.

  The message transmission unit 42 transmits the output incoming notification message to the incoming terminal B. When the incoming call terminal B cannot receive the incoming call notification message in the out-of-service state, the message transmission unit 42 detects that the incoming call notification message has not been received at the incoming call terminal B, and outputs a response signal to that effect to the SMSC 10.

  Then, the SMSC 10 outputs an incoming call notification message to the SMS-IWMSC / SMS-GMSC 11 again. Thus, the incoming notification message is repeatedly transmitted to the incoming terminal B at regular intervals until the incoming terminal B receives the incoming notification message. Therefore, when the receiving terminal B returns to the service area, the incoming call notification message is automatically received.

  Alternatively, the HLR 30 notifies the SMS-IWMSC / SMS-GMSC 11 that the terminating terminal B has returned to the service area, and the SMS-IWMSC / SMS-GMSC 11 receives an incoming notification message from the SMS-IWMSC / SMS-GMSC 11. The communication system 1 may be configured so as to be output. Even with such a configuration, the receiving terminal B can receive the incoming call notification message in response to the return to the service area.

  The above-described SMSC 10, SMS-IWMSC / SMS-GMSC 11, MSC / VLR 20, HLR 30, and MSC / VLR 40 physically transmit and receive data such as a CPU, RAM as a storage device, ROM, or hard disk. A computer system including a communication module, an input device, an output device, and the like. Each of the above-described functions allows the communication module, input device, and output device to operate under the control of the CPU by loading predetermined computer software on the hardware such as the CPU, RAM, and the like in the RAM, hard disk, etc. This is realized by reading and writing data.

  On the other hand, the transmission terminal A according to the present embodiment includes a reception unit (reception unit) 51, a generation unit (generation unit) 52, and a transmission unit (transmission unit) 53. The receiving unit 51 receives a short message transmitted from the notification system 1 and to which identification information is added. The receiving unit 51 outputs the received short message to the generating unit 52 in accordance with a user operation. The generation unit 52 adds the identification information added to the output short message and generates a reply short message. The content of the message is generated in response to a user input. The transmission unit 53 returns the short message generated by the generation unit 52 to the communication system 1.

  Subsequently, with reference to FIGS. 3 to 6, the operation of the notification system 1 of the present embodiment will be described, and the notification method of the present embodiment will be described.

  As shown in FIG. 3, the presence information of the called party and the receiving terminal information (telephone number) are transmitted to the HLR 30 by the receiving terminal B and registered in advance in the presence information holding unit 34 of the HLR 30 (step S11). Then, at an arbitrary timing, a call request to the receiving terminal B is made by the calling terminal A (step S12). When the call request is received by the call request receiving unit 21 of the MSC / VLR 20, a signal to request reading of the incoming information is output to the HLR 30 by the call request receiving unit 21 together with the calling terminal information and the called terminal information ( Step S13).

  When a signal for requesting reading of incoming information is input by the receiver information reading unit 31 of the HLR 30, a signal requesting to pay out routing information is output to the MSC / VLR 40 by the receiver information reading unit 31. (Step S14). When a signal for requesting the routing information is input to the paging processing unit 41 of the MSC / VLR 40, the paging processing is executed by the paging processing unit 41 (step S15).

  In this embodiment, since the receiving terminal B is out of service, it does not respond to paging. Accordingly, a response signal to the signal requesting to pay out routing information is output to the HLR 30 by the paging processing unit 41 together with information indicating that there is no paging response (step S16). When this response signal is input by the recipient information reading unit 31 of the HLR 30, the identification number is issued by the recipient information reading unit 31, and the incoming history is stored in the incoming history holding unit 32 in association with the identification number. (Step S17; storage step).

  Further, the calling terminal information, the receiving terminal information, and the identification number are output from the recipient information reading unit 31 to the message instruction unit 33, and the message notification process is started (step S18). Then, presence information associated with the receiving terminal information is read from the presence information holding unit 34 by the message instruction unit 33 (step S19).

  Subsequently, the response signal in response to the request signal for requesting to read the incoming information in step S13 is a message together with a signal for instructing creation of a short message including the outgoing terminal information, incoming terminal information, identification number, and presence information. It is output from the instruction unit 33 to the MSC / VLR 20 (step S20).

  Subsequently, as shown in FIG. 4, when a response signal to the signal requesting reading of the incoming call information is input to the MSC / VLR 20, a guidance that the incoming terminal B is out of service is sent to the outgoing terminal A, A voice call disconnection request is transmitted from the MSC / VLR 20 to the calling terminal A (step S21). In response to the disconnection request, a voice call release request is transmitted from the calling terminal A to the MSC / VLR 20 (step S22), and a release response is transmitted from the MSC / VLR 20 to the calling terminal A (step S23).

  Subsequently, a waiting process for releasing the radio resource between the MSC / VLR 20 and the calling terminal A is performed by the radio resource control unit 24 of the MSC / VLR 20 (step S24). At this time, the radio resource between the MSC / VLR 20 and the calling terminal A is in an established state.

  Then, a signal instructing creation of a short message is input to the message creation unit 22 of the MSC / VLR 20, and information based on the presence information of the receiving terminal and a message for prompting transmission of the short message to the called party are messages. Created by the creating unit 22 (step S25). The telephone number of the called party is set by the message creating unit 22 as the sender of the created short message (step S26).

  An identification number is added to the short message, and the short message is distributed by the message transmission unit 23 (step S27; first transmission step). This short message is received at the calling terminal A when the caller hangs up. When the short message is received by the calling terminal A, a message delivery response is transmitted from the calling terminal A to the MSC / VLR 20. Through the above procedure, a short message that prompts the caller to send a message to the callee can be transmitted to the caller terminal A.

  The case where the caller creates a message for the callee and returns it to the received short message will be described with reference to FIGS.

  As shown in FIG. 5, when the caller creates and sends a short message to the callee, a signal requesting to send the created short message is sent together with the telephone number and identification number of the receiving terminal B. Then, it is transmitted from the calling terminal A to the MSC / VLR 20 (step S31). When a signal requesting transmission of a short message is received by the message receiving unit 25 of the MSC / VLR 20 (receiving step), the signal requesting transmission of the short message is identified from the telephone number of the receiving terminal B. Along with the number, the message receiver 25 transmits the message to the SMS-IWMSC / SMS-GMSC 11 (step S32).

  When a signal requesting transmission of a short message is transmitted to the SMS-IWMSC / SMS-GMSC 11, a response signal indicating that a short message is to be transmitted is transmitted to the calling terminal A by the message receiving unit 25 (step S33). On the other hand, when a signal requesting transmission of a short message is received by the SMS-IWMSC / SMS-GMSC 11, the signal requesting transmission of a short message is sent together with the telephone number and identification number of the receiving terminal B. , SMS-IWMSC / SMS-GMSC11 outputs to SMSC 10 (step S34).

  When a signal requesting transmission of a short message is input by the message reception unit 12 of the SMSC 10, a signal indicating that a short message transmission request has been received is sent to the SMS-IWMSC / SMS-GMSC 11 by the message reception unit 12. It is output (step S35) and transmitted to the MSC / VLR 20 (step S36). Then, the MSC / VLR 20 transmits a signal indicating that the short message transmission request has been accepted to the transmitting terminal A (step S37), and a response signal to the signal is returned from the transmitting terminal A to the MSC / VLR 20 (step S37). S38).

  On the other hand, as shown in FIG. 6, when a signal indicating that a short message transmission request has been received is output to the SMS-IWMSC / SMS-GMSC 11 by the message receiving unit 12, an identification number is included in the received short message. It is determined by the identification number determination unit 13 (step S39). In the present embodiment, since the identification number is included, a signal for requesting the information of the terminal B (the called party) of the short message is sent together with the telephone number and the identification number of the called party in the message creating unit 14 of the SMSC 10. Is output to the HLR 30 (step S40).

  When the HLR 30 inputs a signal requesting information on the receiving terminal B of the short message, the incoming call history associated with the identification number is read from the incoming call history holding unit 32 in the HLR 30 as the incoming callee information (step S30). S41). Then, the incoming call history is output from the HLR 30 to the SMSC 10 as a response to the callee information (step S42). In the HLR 30, when the incoming call history is output to the SMSC 10, the corresponding incoming call history is deleted from the incoming call history holding unit 32 (step S43).

  In the SMSC 10, when an incoming history is input, the message accepted by the message accepting unit 12 and the incoming history are integrated, and an incoming notification message is created by the message creating unit 14 (step S44; creating step). When the incoming call notification message is created, a signal requesting to transfer the incoming call notification message to the receiving terminal B is output to the SMS-IWMSC / SMS-GMSC 11 by the message creation unit 14 (step S45).

  Then, an incoming notification message transmission process is performed in the SMS-IWMSC / SMS-GMSC 11, the MSC / VLR 40, and the incoming terminal B (step S46; second transmission step). When the receiving terminal B cannot receive an incoming call notification message in an out-of-service state, this incoming call notification message transmission processing is performed at regular intervals until the incoming terminal B is detected to have received the incoming call notification message, or The process is performed again when the HLR 30 is notified that B has returned to the service area. Thereby, when the receiving terminal B returns to the service area, it automatically receives the incoming call notification message. When the incoming call notification message is transmitted to the receiving terminal B, a response signal indicating that the short message has been transferred is transmitted from the SMSC 10 to the SMS-IWMSC / SMS-GMSC 11 and the series of processing ends.

  As described above, in the notification system 1 according to the present embodiment, when a call request is made from the calling terminal A to the receiving terminal B, if the receiving terminal B cannot receive the call, the calling terminal information, the receiving terminal information, An incoming call history including is generated. Then, the incoming call history and the paid identification number are stored in association with each other. Subsequently, by sending a short message to which the identification number is added to the calling terminal A, it is possible to prompt the caller to create a message for the callee. For example, if the caller replies to the short message received, the message to the callee can be easily transmitted to the notification system. At the same time, a short message including an identification number that can identify the incoming call history is transmitted to the notification system 1.

  Then, the notification system 1 creates an incoming notification message by integrating the incoming call history associated with the identification number added to the received short message into the short message, and transmits it to the incoming terminal B. Thereby, the incoming call notification message in which the incoming call history and the message from the caller to the callee are integrated can be transmitted to the call receiving terminal B. Therefore, the called party can know the fact that there is an incoming call and can easily know the message from the calling party in association with the incoming call.

  Further, in the notification system 1 according to the present embodiment, the message transmission unit of the MSC / VLR 20 uses the radio resource without releasing the radio resource when it is detected that the receiving terminal B cannot receive the call. After 23 transmits the short message to the calling terminal A, the radio resource is released. Therefore, it is possible to omit a procedure for establishing a radio resource necessary for transmitting a short message.

  The notification system 1 of this embodiment is not limited to the above, and various modifications are possible.

  For example, without executing the processing of steps S14 to S16 in FIG. 3, it is recognized that the receiving terminal B is out of service based on the information registered in the HLR 30, and the incoming call history is stored (step S17). You may comprise.

  Further, for example, the recipient information reading unit 31 of the HLR 30 accesses the presence information holding unit 34 and notifies the presence information of the called party (Mr. B) stored in the presence information holding unit 34 in the guidance in step S2 of FIG. You may make it do.

  Further, for example, the transmission of the signal requesting the delivery of the short message in step S27 may be made before the voice call disconnection request in step S21.
