Description

  The present invention relates to a character message communication system for transmitting and receiving character messages between mobile terminals and information terminals connected via a network. In particular, for sending and receiving text messages with strong immediacy according to the status of the sender and receiver between a plurality of mobile terminals and information terminals connected to a computer network such as a mobile communication network or a packet switching network. The present invention relates to a text message communication system.

  In the present invention, the packet switching network is a network for connecting a personal computer (PC), a workstation (WS), a PDA (Personal Digital Assistants), etc., for example, the Internet, a LAN (Local Area Network), or an intranet. Can be mentioned.

  The mobile terminal is not particularly limited as long as it can transmit and receive character information via a mobile communication network, and examples thereof include a mobile phone, a PHS, a car phone, and a pager. The information terminal is not particularly limited as long as character information can be transmitted and received via a network, and examples thereof include a personal computer (PC), a workstation (WS), and a PDA (Personal Digital Assistants).

  FIG. 21 shows a conceptual configuration of a conventional text message communication system using a mobile phone, a PHS, and the like and a center that relays them.

  The mobile terminal A transmits a text message addressed to the mobile terminal B to the text message center by radio (1). The center grasps the state of each mobile terminal by the wireless state detection unit. If the mobile terminal B is receivable, the character message is sent to the mobile terminal B. If the mobile terminal B cannot receive it outside the wireless area or the like, the center stores the text message in the storage unit (2), and sends the text message when the mobile terminal B becomes ready to receive (3, 4, 5, 6, 7). In some cases, the mobile terminal B obtains a text message stored in the center by connecting to the center. Further, there is a case where a text message is directly sent from the mobile terminal A to the mobile terminal B without going through the center. In this case, the text message is not received if the transmission partner is out of the wireless area or on the phone.

  In the system shown in FIG. 21, the e-mail is set to be forwarded to the designated address in advance, and the mail arriving at the designated address is stored in the center as a text message to the mobile terminal. Link (9). In addition, the sender, title, e-mail importance, etc. are set in advance as the conditions for transferring mail to the mobile terminal. When an e-mail that meets the conditions arrives at the center, the mail is transferred to the mobile terminal. Some will do. Conversely, when a mobile terminal inputs a mail address as a destination, the center sends a text message as an electronic mail (8).

  In addition to the above, there is already a system in which an e-mail server detects the arrival of an e-mail and notifies a mobile terminal set in advance together with information such as the sender, title, and time of the e-mail.

On the other hand, with regard to detection of the other party status in the network, there are provided services such as network connection status, usage status management of certain services (such as chat and electronic conference), presence management, digitized destination display version, etc. .
JP-A-10-066134 JP-A-9-191309 JP 7-72923 A Japanese Patent Laid-Open No. 10-185599 Japanese Patent Laid-Open No. 10-107914 Japanese Patent Laid-Open No. 10-107835 Japanese Patent Laid-Open No. 10-13460 JP-A-8-256216 Japanese Patent Laid-Open No. 10-4432 JP-A-5-167640

  However, in a conventional text message communication system, a text message from a mobile terminal is forwarded to an electronic mail only when preset. The received message cannot be received by the mobile terminal unless the setting once performed is cancelled. Moreover, this setting / cancellation is very troublesome. In addition, regardless of the state of the other party, the caller uses a character message transmission method such as e-mail or transmission to a mobile terminal. For this reason, selection or switching of the transmission mode according to the other party state which changes dynamically is not performed.

  For example, when the other party receiving the text message is connected to the network with a PC or the like, it is more convenient for replying to receive the text message on the PC instead of the mobile terminal, and the text message can be transmitted immediately. . Furthermore, although the text message of the mobile terminal is accumulated when the other party cannot receive, the caller cannot know that it cannot be received immediately. In this case, even if it is desired to convey a message in real time, if the other party does not see the transmitted text message, it is impossible to know whether it is necessary to take other measures or measures.

  In addition, the linkage of text message communication between mobile terminals and PCs is limited, and text can be freely used on the information terminal used by the other party and further by using the network application used by the other party. The message cannot be sent. For this reason, even if it is known that the partner is connected to the network or network service at the destination, it is inconvenient because communication according to the partner state cannot be performed.

  Furthermore, for example, the e-mail system can notify the sender that the sent mail did not reach the other party, but did not refer to it by a certain time, and the other party did not read it during a network service. Does not manage dynamically changing transmission results. The present invention relates to a character message communication system, a character message communication device, a character for transmitting and receiving character messages in real time according to the usage state of a dynamically changing information terminal using a mobile terminal such as a mobile phone or a PC. It is an object to provide a message communication server, a computer-readable recording medium recording a character message communication program, a computer-readable recording medium recording a character message communication management program, a character message transmission / reception method, and a character message communication management method.

Each information terminal reports an operation state such as a connection state with a communication line to the server, so that the server grasps the operation state of the information terminal. For example, when a user A sends a text message from an information terminal on one communication line to another user B via the server, the server determines whether the PC of user B is connected to the communication line. If it is connected, a character message is transmitted to User B's PC. If User B's PC is not connected to the communication line, the server transfers a text message to User B's mobile phone.

In the server, the determination unit determines to transmit the text message using the network application running on the information terminal of the transmission destination. For example, a text message is transmitted by e-mail if the destination PC is using an e-mail application, or by chat if IRC is being used.

In FIG. 7, an unread message from user B is a message transmitted according to the present invention. FIG. 8 shows an example of a screen when a text message is received while using the IRC application. When these Internet applications are being used, the service detection unit 22 of the PC client 3 detects that the mail has been read or a response input to the chat, and notifies the server 1 of it.

(2) Operation State Notification Process When the PC is turned on, the operation state notification process shown in FIG. 9 and the connection state notification process shown in FIG. 10 are started. First, in step S1, the operation state of the PC client 3 is monitored by the network service detection unit 22 and the PC operation detection unit 23.

  In step S2, it is determined whether or not there is a change in the operation state. If there is a change, a new state is notified to the state setting unit 24 by the service detection unit 22 or the PC operation detection unit 23, and the process proceeds to step 3. If there is no change in the operating state, the process returns to step S1.

  In step S <b> 3, the state setting unit 24 that has received the notification notifies the server 1 of a new operation state. At this time, information specifying the user such as the user name and IP address is added and notified. And it returns to step S1 again and monitors that a new state change arises.

  That is, in steps S1 to S3, processing for notifying the server 1 of changes in the operating state of the PC client is performed.

  On the other hand, the PC operation detection unit 23 performs connection state notification processing shown in FIG. 10 in addition to monitoring and detection of PC operations in Steps S1 and S2, and notifies the server 1 of the connection state.

  First, in step S21, it is determined whether or not the PC client 3 is connected to the Internet 2. If it is determined that the connection is established, the process proceeds to step S22. If it is not connected, it returns to step S21 again and repeats the said determination.

  In step S <b> 22, the PC operation detection unit 23 transmits a connection notification to the server 1 via the state setting unit 24.

  In step S23, the elapse of the predetermined time T is waited, and when it elapses, the process returns to step S21 again to repeat the determination and the connection notification.

  That is, in steps S21 to 23, while the PC client 3 is connected to the Internet 2, a process of transmitting a connection notification to the server 1 every predetermined time T is performed.

(3) Transmission Process When the PC is turned on, the transmission process shown in FIG. 11 is started in parallel with the operation state notification process and the connection state notification process.

  In step S31, it is determined whether or not the other party to whom the text message is to be transmitted is selected. If the other party is selected, the process proceeds to step S32. Otherwise, this step is repeated again, and the process waits until the other party is selected.

In step S32, the character message transmission window of FIG. 5 is opened, and input of the character message to be transmitted is accepted. In step S33, when the “Send” button is pressed, the input text message is transmitted together with the sender name, and the process returns to step S31.
(4) Reception Processing When the PC is turned on, the reception processing shown in FIG. 12 is started in parallel with the above processing.

  First, in step S41, reception from the server 1 is waited, and if there is reception, the process proceeds to step S42.

  In step S42, it is determined whether or not a text message is received from another user. If a text message is received, the process proceeds to step S43. Otherwise, the process proceeds to step S50 described later.

  In step S43, the reception window illustrated in FIG. 6, 7 or 8 is opened, and the received text message is notified to the user. In addition, a transmission source number, for example, an IP address included in the transmitted text message is acquired.

  In step S44, it is determined whether or not a response button has been pressed. If the rightmost discard button has been pressed or the window has been closed, the process moves to step S45. If the response button is pressed, the process proceeds to step S46.

  In step S45, a read notification for notifying that the text message has been read is transmitted to the server 1.

  In step S46, it is determined whether or not the pressed response button is for a telephone. If the telephone button is pressed, the process proceeds to step S47. When the response button by the text message is pressed, the process proceeds to step S48.

  In step S47, the mobile phone number of the other party notified together with the text message or the telephone number of the current location is dialed, and the process returns to the reception standby state in step S41.

  In step S48, the character message transmission window shown in FIG. 5 is opened to accept input of a character message. By inputting a text message and pressing the “Send” button in step S49, the input text message is transmitted. The destination of the text message to be sent is set to the source of the text message acquired earlier.

  If it is determined in step S42 that the text message is not received, the process proceeds to step S50. In step S50, it is determined whether or not the received result is a text message transmission result. If it is a transmission result, it will transfer to step S51, will notify a user of the transmission result notified from the server 1, and will return to the reception standby state of step S41. For example, a transmission result such as “020-222-222 Ate Message Ha PC DeYomarezu Keitaidenwa to Tensoushi Mashita” is displayed on the screen. If it is not reception of a transmission result, it will transfer to step S52.

  In step S52, it is determined whether or not a read notification for the transmitted text message is received. If it is already read notification, the process proceeds to step S53, and the user is notified that the transmitted text message has been read by the other party. For example, as shown in the mail result display of FIG. 7, the text message may be displayed as a list together with the transmission message, and the corresponding message portion may be displayed by shading or color. Thereafter, the process returns to the reception standby state in step S41.

[Processing on the server]
Next, the flow of processing performed by the server 1 will be described using a flowchart. In the following description, it is assumed that the operation state of each PC client is the state shown in FIG. 2, and the server 1 is capable of handling e-mail and IRC applications used in the PC client. In order to make the explanation easy to understand, a case where a text message is sent from the mobile phone 5A of the user A to the mobile phone of another user C will be described as an example.

  (1) Determination Process First, the flow of the process performed by the determination unit 10 will be described based on FIG.

  In step S61, the determination unit 10 receives the text message from the mobile phone 5A of the user A from the reception unit 13 of the server 1, and the process is started. The text message includes user C's mobile number “020-444-4444”, text message content “15 Ginikisha Yoteides”, mobile phone number “020-111-1111” of user A who is the sender as sender information, It includes the presence / absence of notification of the transmission result.

  When a character message is transmitted from the PC client 3 by each application, the character message receiving unit 7 of the server 1 receives the character message and notifies the determining unit 10. In this case, the information specifying the sender and the receiver is a user name and an IP address, and is an e-mail address when transmitted by electronic mail, and a nickname when transmitted by IRC.

  In step S62, the determination unit 10 searches the state storage unit 9 using the received mobile number “020-444-4444” as a key, and acquires the state of the user C. Next, the determination unit 10 acquires the state of the caller in the same manner.

  In step S63, it is determined whether or not the partner state has been acquired in step S2. In this example, when the state storage unit 9 is searched using the mobile number “020-444-444” as a key, it is determined that the state of the user C exists, and the process proceeds to step S64. If there is no state, it will transfer to step S70 mentioned later.

  In step S <b> 64, the determination unit 10 determines whether the user B's PC client 3 is connected to the Internet 2. In this example, since the IP address of user C is not blank, it is determined that the user C is connected, and the process proceeds to step S65. If it is not connected, a character message is transmitted to the transmission part 14, and it transfers to step S74 mentioned later.

  In step S65, it is determined whether or not the user C's PC client 3 is being operated by the user C. That is, if the screen saver is activated in the PC client 3 of the user C, it is assumed that the user C is not in front of the PC and the mobile phone is selected as the transmission destination. The received character message is stored in the message storage unit 12. Conversely, in this example, since the screen saver is not activated on the PC of user C, the partner is assumed to be in front of the PC, and the PC client of user C is selected as the transmission destination, and the process proceeds to step S66.

  In step S66, it is determined whether or not the Internet application is operating on the PC client 3 of the user C. Specifically, referring to FIG. 2, the mail address of the user C is described, and it can be seen that the mail is being used on the PC. In this case, the process proceeds to step S67. Conversely, if the Internet application is not operating, the process proceeds to step S68 described later.

  In step S <b> 67, the determination unit 10 acquires parameters necessary for transmitting the text message by the electronic mail application, for example, a mail address from the state storage unit 9. At this time, the name of the user A who is the caller is also acquired.

  In step S <b> 68, the determination unit 10 acquires parameters necessary for directly transmitting the text message, for example, an IP address, from the state storage unit 9. At this time, the name of the user A who is the caller is also acquired.

  In step S69, the determination unit 10 passes the character message and the information acquired in step S67 or step S68 to the character message transmission unit 6 to request transmission. In this example, the text message is assembled into a mail message by the text message transmission unit 6 and transmitted to the mail address of the user C. In the received PC client 3 of the user C, the character message is displayed in the window shown in FIG. In the case of this mail, the message transmitted from the server is often sent via the mail server until it reaches the client.

  If it is determined in step S63 that the PC client of user C is not operating, the process proceeds to step S70.

  In step S <b> 70, the determination unit 10 acquires parameters necessary for transmission to the mobile phone of the user C, such as a mobile number, from the state storage unit 9. At this time, the name of the user A who is the caller, the mobile phone number of the caller A, and the telephone number of the current location are also acquired. If it is determined in step S63 that there is no state and the process proceeds to step S70, the number of user C cannot be obtained, so the next step is performed using the partner number “020-444-4444” sent to the previous message reception character as the partner number. S71 is performed.

  In step S71, the determination unit 10 passes the information acquired in step S70 to the transmission unit 14 and requests wireless transmission.

  In step S72, the determination unit 10 determines whether it is possible to notify the server 1 that the user C's mobile phone has read the text message, and whether the caller requests notification. If both are possible, the process proceeds to step S73. If notification from the mobile phone is impossible, the process returns to step S61 and waits for reception of the text message.

  In step S73, the transmission notification including the text message, the sender name, the recipient name, the sender terminal, and the receiver terminal transmitted by the determination unit 10 is transmitted to the notification management unit 11, and the process returns to step S61 again. As will be described later, the notification manager 11 writes the contents of the received transmission notification in the message table.

  If it is determined in step S64 or S65 that the user C's PC client is not connected to the Internet or the PC is not currently in use, the process proceeds to step S74.

  In step S74, the determination unit 10 determines whether or not the caller A is requesting notification of a transmission result. If it is determined that the request has been made, the process proceeds to step S75. If not, the process proceeds to step S10, and transmission to the mobile phone is performed.

  In step S75, the determination unit 10 creates a result notification addressed to the sender that the text message has been once stored in the message storage unit 12.

  In step S76, the determination unit 10 determines a transmission mode according to the state of the caller A, and transmits the result notification created in step S75. That is, when the PC client of the receiver C is not connected to the Internet and transmits a text message to the mobile phone of the receiver C, the caller A is notified of the text message to that effect. That is, the message is sent to the determination unit 10 and transmitted to the caller A by an appropriate method.

(2) State Management Process Next, the flow of the state management process for managing the operation state of the PC client in the server 1 will be described with reference to the flowchart shown in FIG.

  First, in step S81, a change in the operation state of the user's PC client 3 is notified from the state setting unit 24 of the PC client to the state management unit 8 of the server 1, and processing is started.

  In step S82, based on the content received by the state management unit 8, the content of the state storage unit 9 is updated to the latest content for each user.

  In step S83, the state management unit 8 further notifies the notification management unit 11 of a change in the operation state.

(3) Notification Management Processing Next, notification management processing for notifying the sender from the server 1 will be described using the flowchart shown in FIG. In this embodiment, four processes are performed: (i) main process, (ii) time-out process of accumulated character message, (iii) process of accumulated character message according to the destination state, and (iv) other process. .

(I) Main Process First, in step S91 in FIG. 15, the process is started by receiving an event such as a message, a timeout notification, or a user activity state notification.

  In step S92, it is determined whether or not the received event is a text message. If it is a text message, the process proceeds to step S93. If it is not a text message, the process proceeds to step S100 described later.

  In step S93, it is determined whether or not the received text message is a transmission notification notified from the determination unit 10 in step S73 of FIG. 13. If it is a transmission notification, the process proceeds to step S94. If the text message is not a transmission notification, no processing is performed and the process returns to step S91.

  In step S94, the timer ID is written in the message table in addition to the contents of the character message, the sender / receiver of the character message, and the transmission / reception type included in the transmission notification, and the process proceeds to step S95.

  In step S95, a timer for counting a predetermined time is started, and the message table is managed together with the timer ID.

  If it is determined in step S92 that the text message is not a transmission notification or a normal text message, the process proceeds to step S100.

  In step S100, it is determined whether or not the received event is a time-out notification. If it is time-out notification, the process proceeds to the time-out processing routine in step S300, and the character message accumulated in the message table is deleted. I do. This timeout process will be described later. If it is not a timeout notification, the process proceeds to step S200.

  In step S200, it is determined whether or not the received event is a notification of the operating state of the PC client. If the received event is a notification of the operating state, the process proceeds to the operation state processing routine of step S400. Otherwise, the process proceeds to step S500, and another processing routine is performed. The operation state processing routine in step S400 and other processing routines in step S500 will be described later.

(Ii) Time-out process When it is determined in step S100 that a time-out has been notified, the process proceeds to a time-out process routine in step S300. FIG. 16 is a flowchart showing the flow of the timeout process routine.

  First, in step S301, it is determined whether a time-out character message remains in the message table. If it remains, it is determined that no read notification has been received from the recipient within a predetermined time, and the process proceeds to step S302. If not, the process returns to the main routine of FIG.

  In step S302, it is determined whether or not the destination type of the timed-out text message is a mobile phone. If it is a mobile phone, the process proceeds to step S303, and if it is a PC client, the process proceeds to step S307.

  In step S303, it is determined whether or not the caller wishes to be notified of the text message transmission result. If so, the process proceeds to step S304. If not desired, the process returns to the main routine of FIG.

  In step S304, an unread result notification indicating that the transmitted text message has not been read is created, and the process proceeds to step S305.

  In step S305, the determination unit 10 is notified of the created unread result notification. The determination unit 10 selects an appropriate transmission means and transmission method from the state of the caller, and transmits an unread result notification to the caller.

  In step S306, the corresponding character message entry is deleted from the message table, and the process returns to the main routine of FIG.

  That is, in Steps S303 to S306, for the text message that was transmitted to the mobile phone but timed out, a result notification indicating that “the text was transmitted to the mobile phone but was not read” is transmitted to the sender.

  If it is determined in step S302 that the transmission destination is a PC client, the process proceeds to step S307.

  In step S307, as in step S303, it is determined whether or not the sender desires notification of the transmission result. If so, the process proceeds to step S308. If not desired, the process returns to the main routine of FIG.

  In step S308, a wireless transmission result notification for transferring and transmitting the text message to the mobile phone is created.

  In step S309, the determination unit 10 is notified of the created wireless transmission result notification. Upon receiving the notification, the determination unit 10 notifies the caller of the result notification in a transmission mode according to the operating state of the caller's PC client.

  In step S310, the character message is transferred to the transmission unit 14, and the entry of the corresponding character message is deleted from the message table.

  In step S311, transmission information necessary for transmission to the mobile phone such as the number of the mobile phone of the other party is acquired from the state storage unit 9.

  In step S312, the transmission unit 14 is notified of the transmission information and requests transmission of a text message.

  In step S313, it is determined whether it is possible to notify that the destination mobile phone has read the text message, and if possible, the process proceeds to step S314. Otherwise, the process returns to the main routine of FIG.

  In step S314, a transmission notification including the transmitted text message, sender / receiver, transmission / reception type, and the like is issued. This transmission notification is written in the message table in step S94 described above.

(Iii) Operational State Processing If it is determined in step S200 that the received event is a change notification of the operational state of the PC client, the process proceeds to the operational state processing routine of step S400 shown in FIG. FIG. 17 is a flowchart showing the flow of the operation state processing routine.

  First, in step S401, it is determined whether or not there is a text message addressed to the PC client whose operation state has changed in the message table. If there is, the process proceeds to step S402. If not, return to the main routine.

  In step S402, it is determined whether or not the state change corresponds to “disconnection from the Internet” or “screen saver being activated”. If so, the process proceeds to step S403. If not cutting, the process proceeds to step S410, which will be described later.

  In step S403, it is determined whether or not the caller wants to be notified of the transmission result. If so, the process proceeds to step S404. If not desired, the process proceeds to step S406.

  In step S404, it is assumed that the character message previously sent to the PC client has not been read. Notify the determination unit 10. The determination unit 10 determines a transmission mode according to the state of the caller, and requests the character message transmission unit 6 or the transmission unit 14 to transmit.

  In step S405, the corresponding character message is transferred to the transmission unit 14, and the entry of the corresponding character message is deleted from the message table.

  In step S406, transmission information necessary for transmission to the mobile phone, such as the mobile phone number, is acquired from the state storage unit 9.

  In step S407, the acquired transmission information is passed to the transmission unit 14 to request transmission.

  In step S408, it is determined whether it is possible to notify that the destination mobile phone has read the text message. If possible, the process proceeds to step S409. Otherwise, the process returns to the main routine of FIG.

  In step S409, a transmission notification including the transmitted text message, sender / receiver, transmission / reception type, and the like is created. This transmission notification is written in the message table in S94 of the main routine.

  If it is determined that the state change notified in step S402 is not disconnection or activation of a screen saver, the process proceeds to step S410.

  In step S410, it is determined whether or not the notified state change is an end notification of the Internet application that has already been transmitted. If it is the end notification, the process proceeds to step S411, and if not, the process proceeds to the main routine in FIG.

  In step S411, the transmission information necessary for transmission to the PC client, for example, an IP address, is acquired with reference to the state storage unit 9.

  In step S412, the acquired transmission information and text message are passed to the transmission unit 14 to request transmission.

  In step S413, the corresponding character message is deleted from the message table.

  In step S414, it is determined whether or not the sender wishes to be notified of the transmission result. If so, the process proceeds to step S415. If not desired, the process proceeds to the main routine shown in FIG.

  In step S415, it is assumed that the text message previously sent on the PC client's Internet application has not been read. Create and notify the decision unit 10. The determination unit 10 selects a transmission means and a transmission method according to the state of the caller, and requests the character message transmission unit 6 to transmit.

(Iv) Other Processes In step S200, if it is determined that the received event is not an operation state change notification, the process proceeds to another process routine in step S500. FIG. 18 is a flowchart showing the flow of processing of another processing routine.

  First, in step S501, it is determined whether the received event is a text message acquisition notification from the transmission destination. For example, when the text message receiving unit 7 or the receiving unit 13 receives an acquisition notification from a PC client or a mobile phone that has received a text message, the acquisition notification is transmitted to the notification management unit 11. In some cases, the character message receiving unit 7 detects a reply to an e-mail or a confirmation command transmitted in the same channel of the IRC, and transmits an acquisition notification to the notification management unit 11. If it is a text message acquisition notification, the process proceeds to step S502; otherwise, the process proceeds to step S503 described later.

  In step S502, the entry of the corresponding character message is deleted from the message table, and the process returns to the main routine of FIG.

  In step S503, it is determined whether or not the received event is a notification to the effect that the text message has been stored in the mobile phone, and if it is a text message storage notification, the process proceeds to step S504. Otherwise, the process returns to the main routine of FIG. That is, there is a case where a text message is transmitted to the mobile phone but is not immediately sent to the other party, and the text message is stored in the message storage unit 12. In this case, accumulation notification is sent from the transmission unit 14 to the notification management unit 11.

  In step S504, it is determined whether or not the caller wants to be notified of the transmission result. If so, the process proceeds to step S505. If not desired, the process proceeds to the main routine shown in FIG.

  In step S <b> 505, a storage result notification indicating that the text message has been stored is created and transmitted to the determination unit 10. The determination unit 10 determines a transmission mode according to the state of the sender, and requests the transmission unit 6 or the transmission unit 14 to transmit the accumulation result notification.

  In the above processing, the time-out time and the notification setting when the text message is not read immediately may be set in the server from the mobile phone or PC client via the Internet. It is also possible to set with a text message in a predetermined format.

<Second Embodiment>
By using the character message communication system shown in the first embodiment and sending a character message of a predetermined format from the mobile terminal, the mobile terminal can acquire any information service.

  For example, FIG. 19 shows a configuration diagram of a character message communication system that changes or refers to the operation state of the PC client managed by the server 1 from the mobile terminal. In FIG. 19, the information server 30 is used as one of the PC clients. The mobile terminal 5 transmits the character message in a format for transmitting the character message to the PC client, and the information server 30 impersonates the PC client and sets the operation state in the server 1.

  For example, a destination or schedule information is sent from a certain mobile terminal 5 to a telephone number of the information server 30 as a text message in a predetermined format. As described in the first embodiment, the server 1 sends a text message to the information server 30. The information setting unit 26 of the information server 30 that has received the text message analyzes the received text message and notifies the status management unit 8 of the server 1 of information that changes the status setting of the sender.

  When a mobile terminal sends a text message to the telephone number of the information server 3 to the telephone number of the information server 30 along with the telephone number of the other user, Server 1 transmits the text message to information server 30.

  The information acquisition unit 25 of the information server 30 analyzes the received text message and acquires the operating state of other PC clients from the server 1 using the telephone number as a key. The acquired information is sent as a text message from the information server 30 to the transmitted mobile terminal number. Therefore, for example, it is possible to know the current location of another user and make a call.

<Third Embodiment>
As shown in FIG. 20, a wireless server 1b that is independent from the character message server 1a may be provided, and the message storage unit 12 and the wireless state detection unit 15 may be provided in the wireless server 1b. In that case, the receiving part 13a, b and the transmission part 14a, b are provided in each of the character message server 1a and the wireless server 1b. Further, a configuration may be adopted in which an independent state management server 1 is further provided and the state management unit 8 and the state storage unit 9 are provided in the state management server 1c.

<Example of Fourth Embodiment>
When a text message is transmitted from a PC client or a mobile phone, a telephone inquiry destination may be transmitted together with the text message so that the other party can reply immediately by telephone. As soon as the recipient receives the text message, he or she can call using that number and talk to the other party. For example, the determination unit 10 refers to not only the receiver state but also the state of the sender, and if the telephone number of the current location of the sender is set in the state storage unit 12, the telephone number is returned. As a text message. If the telephone number of the current location is not set, the telephone number of the mobile phone may be transmitted as a return telephone number together with the text message.

<Fifth Embodiment>
In addition to the above-described exemplary embodiment, it is also conceivable to add functions to the server 1 such as acquiring a schedule of a specific condition, acquiring a telephone directory, and acquiring an e-mail. Services can be easily added without changing the server configuration.

<Sixth embodiment>
In the above embodiment, only one mobile communication network and one Internet are shown, but there may be a plurality of them. Since the state management unit of the server 1 holds only one active state per user, it is possible to cope with an increase in the number of networks connected to the server 1.

  The present invention can be applied to a text message communication system for transmitting and receiving text messages between mobile terminals and information terminals connected via a network.
