In the case the interlock flag represents "interlocked packet communication", the contract state of a user as well as the state of access point are confirmed. Based on the confirmation result, either a transmission process or a transmission suppression process is performed for the SMS message.

Description

  The present invention relates to an SMS message relay apparatus, an SMS message transmission source apparatus, a communication terminal apparatus, an SMS message distribution system, and an SMS message distribution method for controlling transmission of a message (hereinafter, SMS message) transmitted by SMS (Short Message Service). About.

  In general, there are two types of SMS-Push services that transmit SMS messages. That is, a service that terminates when an SMS message arrives (hereinafter referred to as service A), and a communication terminal device (such as a mobile phone) that receives the SMS message is triggered by a packet switching (PS) network. There is a service (hereinafter referred to as service B) that performs transmission to (hereinafter referred to as PS transmission).

  For example, service B is used as a notification of new mail. Specifically, the SMS server sends a reception notification as an SMS-Push message when mail arrives at the mail server, even if the user does not periodically access from the communication terminal device to confirm whether the mail has arrived. Therefore, the mail can be automatically acquired upon receiving the notification. That is, when a mail addressed to a communication terminal device arrives at the mail server, an SMS-Push message notifying that is sent to the communication terminal device, and the communication terminal device automatically sends a PS and sends a mail from the mail server. (For example, Patent Document 1, Paragraph 0002).

  In addition to mail, it is also used for various content providing services using SMS-Push messages. For example, when the content is information that changes from moment to moment, such as news and weather forecasts, information that is updated by the SMS-Push message is periodically delivered by PUSH, and the communication terminal device receives the SMS-Push message. There is a service system in which a user can browse news and the like at the timing when information is updated by starting an application such as a WWW (World Wide Web) browser and a news reader and acquiring update information.

  Here, a general SMS-Push service will be described with reference to FIG. In FIG. 11, an SMS-Push message 101 transmitted by a Push server 11 operated by a carrier (hereinafter referred to as a communication carrier) that is a company that provides a communication service is referred to as a short message service center (Short Message Service Center; It is received by the communication terminal device 31 via the SMSC 21, an exchange (not shown) in the core network 100, and a radio base station (not shown). In the communication terminal device 31, based on the content of the SMS-Push message 101, an internal server 41 operated by a communication company via an exchange (not shown) and a radio base station (not shown) in the core network 100. PS communication 102 is performed.

  As for the SMS-Push message 103 transmitted by the external Push server 12 operated by a company other than the communication company, the Push-gateway server (Push-GW) 20, the SMSC 21, an exchange (not shown) in the core network 100, The data is received by the communication terminal device 31 via a radio base station (not shown). In the communication terminal device 31, based on the content of the SMS-Push message 102, a company other than the communication company operates through an exchange (not shown) and a radio base station (not shown) in the core network 100. PS communication 104 to the external server 42 is performed.

JP 2008-236790 A

  By the way, in the SMS-Push service, when there is an SMS message transmission request, the SMS message may be transmitted uniformly independently of the operating conditions for PS transmission. In addition, there is a case in which SMS is distributed uniformly without being regulated by SMS and independent of PS transmission. On the other hand, for PS transmission, an operation policy is determined independently of the incoming SMS message. The PS transmission operation policy may be determined based on, for example, the user's contract status, line status, and access point (APN) to be used.

Therefore, even if the SMS message can be received, PS transmission may not be possible. For example, in a service in which the user sets the upper limit of the available amount, in a state where the usage upper limit is exceeded (hereinafter referred to as “use upper limit exceeded state”), even if an SMS message can be received, PS transmission cannot be performed. It is a principle.
Here, in the case of the above service B, it is necessary to activate PS transmission by pseudo Push without making the user aware of it. This is because, if an SMS message can be received but PS cannot be transmitted, the contents such as “Could not be connected” are displayed on the screen of the communication terminal device when PS is transmitted, and the SMS-Push is not intended to be recognized by the user. This is to make you conscious. Displaying such a screen display is not preferable because it may give the user an impression that a failure has occurred in the communication terminal device.

In addition, in the above usage upper limit state, not all PS transmissions should be regulated, but PS transmissions should be permitted for emergency transmissions and the like.
It is also possible that the above message is not displayed by control inside the communication terminal device. However, in a situation where SIM lock-free terminals that can be used simply by replacing a SIM (Subscriber Identity Module) card are widespread, it is difficult to realize such control in all communication terminal devices.
The present invention has been made to solve the above-described problems of the prior art, and the purpose of the present invention is to display the contents such as “could not be connected” on the screen of the communication terminal device, and the impression that a problem has occurred. Providing an SMS message relay device, an SMS message transmission source device, a communication terminal device, an SMS message distribution system, and an SMS message distribution method.

  The SMS message relay device according to the present invention is an SMS message relay device that relays an SMS message from the transmission source device to the transmission destination communication terminal device, wherein the transmission destination communication terminal is added to the SMS message. When the interlock flag indicating whether or not the message is to perform packet communication in conjunction with the arrival of the message in the device indicates that packet communication is interlocked, the user contract of the destination communication terminal device A confirmation processing unit for performing confirmation processing for confirming the status and the state of the access point, and a transmission control unit for performing either transmission processing or transmission suppression processing for the SMS message based on the confirmation result by the confirmation processing unit It is characterized by including. By doing this, SMS messages linked to packet transmission can be appropriately suppressed from being sent to the destination communication terminal device, and contents such as “Could not be connected” are displayed on the screen of the communication terminal device. There is no.

  In addition, the transmission control unit, if the confirmation result indicates that the destination communication terminal apparatus is in a state where packet communication is possible, and if the interlock flag indicates that there is no packet communication interlock, When the transmission destination communication terminal apparatus is in a state where packet communication is not possible, transmission of the SMS message may be suppressed. By doing so, transmission of the SMS message can be appropriately suppressed.

  The transmission message is further added with a permission flag indicating whether or not the SMS message is a message for which packet communication is permitted, such as when the SMS message is urgent. Transmits the SMS message when the permission flag added to the SMS message indicates that packet communication is permitted, and indicates the result of confirmation by the confirmation processing unit when the permission flag indicates that packet communication is not permitted. Based on the state of the communication line, either the transmission process or the transmission suppression process may be performed on the SMS message. By doing so, communication can be performed without being suppressed when there is urgency.

  The SMS message transmission source device according to the present invention includes a link flag indicating whether or not the SMS message is a message for performing packet communication in conjunction with the arrival of the message in the SMS message transmission destination communication terminal device. An SMS message to which the flag addition unit is added, and a transmission unit that transmits the SMS message with the linkage flag added by the flag addition unit to a destination communication terminal device. One of the transmission processing and the transmission suppression processing is performed for the above. In this way, in the SMS message relay device, it is possible to appropriately suppress the transmission of the SMS message linked to the packet transmission to the destination communication terminal device, and the contents such as “could not be connected” are displayed on the communication terminal device. It will not be displayed on the screen.

  The flag adding unit further adds a permission flag indicating whether or not the SMS message is a message that allows packet communication, which is determined in advance when the SMS message has urgency, and the flag adding unit. Thus, either the transmission process or the transmission suppression process may be performed on the SMS message to which the interlock flag and the permission flag are added. By doing so, communication can be performed without being suppressed when there is urgency.

  The communication terminal device according to the present invention includes an interlock flag indicating whether or not the SMS message is a message for performing packet communication in conjunction with the arrival of the message at the destination communication terminal device of the SMS message, and the SMS message is: An SMS message receiving unit for receiving an SMS message to which a permission flag indicating whether or not the packet communication is permitted is added in a case where there is urgency, and the SMS message receiving unit A packet transmission unit that transmits a packet with the linkage flag and the permission flag added, and relays the packet transmitted by the packet transmission unit when performing packet transmission in conjunction with the reception of the SMS message In the device, the interlock flag and the permission flag are added. Characterized in that the to perform either the transmission processing and the transmission suppression process for the packet. By doing so, communication can be performed without being suppressed when there is urgency.

  An SMS message distribution system according to the present invention is an SMS message distribution system that distributes an SMS message from a transmission source device to a transmission destination communication terminal device. The SMS message transmission system receives the message at the transmission destination communication terminal device of the SMS message. In particular, an interlocking flag indicating whether or not the message is for performing packet communication and a permission flag indicating whether or not the message is permitted for packet communication, such as when there is urgency. An SMS message transmission source device including: a flag addition unit to be added to the SMS message; and a transmission unit that transmits the SMS message to which the linkage flag and the permission flag are added by the flag addition unit to a destination communication terminal device. And when the linkage flag indicates that packet communication is linked A confirmation processing unit for performing confirmation processing for confirming a contract state and an access point state of a user of the destination communication terminal device; and, if the permission flag indicates packet communication permission, transmits the SMS message, and A transmission control unit that performs one of transmission processing and transmission suppression processing for the SMS message based on a confirmation result by the confirmation processing unit when the flag indicates that packet communication is not permitted; And an SMS message relay device. In this way, in the SMS message relay device, it is possible to appropriately suppress the transmission of the SMS message linked to the packet transmission to the destination communication terminal device, and the contents such as “could not be connected” are displayed on the communication terminal device. It will not be displayed on the screen.

  The SMS message delivery method according to the present invention is an SMS message delivery method for delivering an SMS message from its source device to a destination communication terminal device, wherein the destination communication terminal is added to the SMS message. When the interlock flag indicating whether or not the message is to perform packet communication in conjunction with the arrival of the message in the device indicates that packet communication is interlocked, the user contract of the destination communication terminal device A confirmation processing step for performing confirmation processing for confirming the state and the state of the access point, and a transmission control step for performing either transmission processing or transmission suppression processing for the SMS message based on the confirmation result by the confirmation processing unit It is characterized by including. By doing this, SMS messages linked to packet transmission can be appropriately suppressed from being sent to the destination communication terminal device, and contents such as “Could not be connected” are displayed on the screen of the communication terminal device. There is no.

  The SMS message further includes a permission flag indicating whether or not the SMS message is a message that allows packet communication, such as when the SMS message has urgency, and the transmission control step. , The SMS message is transmitted when the permission flag added to the SMS message indicates packet communication permission, and the confirmation result by the confirmation processing step when the permission flag indicates packet communication non-permission. Based on the above, either one of transmission processing and transmission suppression processing may be performed on the SMS message according to the state of the communication line. By doing so, communication can be performed without being suppressed when there is urgency.

According to the present invention, an SMS message linked to packet transmission can be prevented from being transmitted to the destination communication terminal device, and contents such as “Could not be connected” are displayed on the screen of the communication terminal device. There is no effect. Further, by suppressing the transmission of the SMS message, it is possible to prevent pressure on radio resources.
Also, when sending SMS messages to the destination communication terminal device is suppressed, not all SMS messages are sent uniformly, but linked to packet communication, which is determined in advance, such as when there is urgency. In some cases, transmission can be permitted.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings referred to in the following description, the same parts as those in the other drawings are denoted by the same reference numerals.
Hereinafter, a configuration example of an SMS message distribution system including an SMS message relay device, an SMS message transmission source device, and a communication terminal device according to the present invention will be described.
(Configuration of SMS message distribution system)
FIG. 1 is a diagram showing the overall configuration of the SMS message delivery system of this example. In the figure, the SMS message delivery system of this example includes a Push server 11 that functions as an SMS message transmission source device, an SMSC 21, a communication terminal device 31 used by a user who is in a contracted state with a communication company, and a core network 100. And an internal server 42 which is a transmission destination of the packet. The core network 100 is configured by devices that relay SMS messages and PS-transmitted packets, such as the exchange 110 and the line / packet exchange 120.

  The SMS message 101 transmitted from the Push server 11 to the communication terminal device 31 is added with a linkage flag and a permission flag described later. The SMS message 101 is received by the communication terminal device 31 via the SMSC 21, the exchange 110, the line / packet exchange 120, and the like. Also, a linkage flag and a permission flag, which will be described later, are added to the packet of the PS communication 102 transmitted from the communication terminal device 31. The packet of the PS communication 102 is received by the internal server 42 via the line / packet switch 120 or the like. That is, the SMS message 101 and the PS communication 102 packet carry the interlocking flag and the permission flag so that the processing by the present system can be realized.

The exchange 110 has, for example, a GMSC (Gateway Mobile Services Switching Center) function. The circuit / packet switch 120 has, for example, functions of MSC (Mobile Services Switching Center) and SGSN (Serving GPRS Support Node).
The Push server 11, the SMSC 21, the internal server 42, the exchange 110, and the line / packet exchange 120 are realized by a general server device that includes a communication interface, a CPU, a storage unit, and the like.

(Example data structure of SMS message)
Here, an example of the data structure of the SMS message 101 in FIG. 1 will be described with reference to FIG.
The SMS message 101 transmitted from the Push server 11 functioning as the SMS message transmission source device is composed of a header part H and a data part D as shown in FIG. The header portion H includes an interlock flag F1 and a permission flag F2. Here, the “SMS message” refers to all signals for transferring an SMS message, including a message for sending an SMS message. In the example of FIG. 2, the interlock flag F1 and the permission flag F2 are placed on the header portion H, but the interlock flag F1 and the permission flag F2 may be transmitted by other methods. For example, these may be placed on a protocol for carrying SMS messages.

  The interlock flag F1 is a flag indicating whether or not the communication terminal apparatus 31 that is the transmission destination of the SMS message 101 is a message that performs packet communication in conjunction with the arrival of the message. That is, the interlock flag F1 is a flag indicating whether the message is an SMS message related to the service A or an SMS message related to the service B.

The permission flag F2 is a flag that indicates whether or not the SMS message is a predetermined message for which packet communication is permitted, for example, when the SMS message has urgency. In addition to the case of urgency, the case where the communication terminal device is set in a locked state (a state in which only the operation of the power switch is not accepted) corresponds to a predetermined message allowing packet communication. The case where the communication terminal device is set to the locked state is, for example, a case where the user loses the communication terminal device.
Similarly, a packet transmitted from the communication terminal device in conjunction with the SMS message has a header portion H and a data portion D, and the header portion H has a linkage flag F1 and a permission flag F2. include.

(Configuration example of Push server 11)
Next, a configuration example of the Push server 11 functioning as an SMS message transmission source device will be described with reference to FIG. In the figure, the Push server 11 of this example includes an SMS-push instruction receiving unit 111 that receives an instruction regarding SMS-push transmission, and a flag adding unit 112 that adds a flag to the SMS message according to the received SMS-push instruction. And an SMS message transmitting unit 113 that transmits the SMS message to which the flag has been added to the destination communication terminal device. These units are functions realized by a CPU (not shown) executing firmware and software programs in the push server 11.
In FIG. 3, only the components that are unique to the present invention are shown, and the Push server 11 also includes other components not shown.

(Configuration example of the exchange 110)
Next, a configuration example of the exchange 110 functioning as an SMS message relay device will be described with reference to FIG. In the same figure, the exchange 110 of this example includes an SMS message receiving unit 1101 that receives an SMS message transmitted from the Push server 11 toward the communication terminal device 31, and an SMS message received by the SMS message receiving unit 1101. , A confirmation processing unit 1102 for performing confirmation processing for confirming the contract state and access point state of the user of the destination communication terminal device, and transmission processing and transmission suppression for the SMS message based on the confirmation result by the confirmation processing unit 1102 A transmission control unit 1103 that performs any one of the processes is included. These units are functions realized by a CPU (not shown) executing firmware and software programs in the exchange 110.
The confirmation processing performed by the confirmation processing unit 1102 indicates that the link flag indicating whether the packet communication is performed in conjunction with the arrival of the SMS message in the destination communication terminal apparatus indicates that the packet communication is linked. In this case, it is a process for confirming the contract state of the user of the destination communication terminal device and the state of the access point.

(Processing by the exchange 110)
Here, processing by the exchange 110 functioning as an SMS message relay device will be described with reference to FIG. FIG. 5 is a flowchart showing processing relating to incoming SMS messages.
First, it is determined whether or not the interlock flag indicating whether or not PS-linked is SMS-Push is a value indicating that there is interlock (step S301). In other words, the service A is “no interlock”, and the service B is “interactive”.
If the linkage flag is a value indicating “with linkage”, the contract status of the user of the communication terminal device that is the destination of the SMS message and the status of the access point are referred to (step S302). Based on these referenced contents, it is determined whether the user is a PS callable user (step S303). In step S303, if the user is not a PS callable user, SMS transmission to the communication terminal device is restricted (steps S303 → S304).

On the other hand, if the user is a PS callable user in step S303, it is further determined whether or not the permission flag indicating whether or not the distribution is permitted even when the line state is stopped is a content indicating “permitted” ( Step S303 → S305). The same applies when the interlock flag is a value indicating “no interlock” in step S301 (step S301 → S305).
In step S305, when the permission flag indicates “permitted”, an SMS message is transmitted to the communication terminal apparatus regardless of the line state (steps S305 → S306). If the content does not indicate “permitted”, the SMS message is transmitted or the transmission is suppressed according to the line state (steps S305 → S307).

(Configuration example of line / packet switch 120)
Next, a configuration example of the line / packet switch 120 will be described with reference to FIG. In the figure, a circuit / packet switch 120 includes a packet receiving unit 1201 that receives a packet transmitted from the communication terminal device 31 and a transmission control unit 1202 that performs transmission control on the packet received by the packet receiving unit 1201. Contains. The transmission control performed by the transmission control unit 1202 is a case where the interlock flag added to the packet received by the packet receiver 1201 indicates that the packet communication is interlocked, and the permission that is also added to the packet. When the flag indicates that the packet communication is permitted, the packet is transmitted. When the permission flag indicates that the packet communication is not permitted, the packet is transmitted according to the state of the communication line.

(Processing by circuit / packet switch 120)
Next, processing by the line / packet switch 120 will be described with reference to FIG. FIG. 7 is a flowchart showing processing related to PS transmission by the line / packet switch 120.
First, it is determined whether or not the interlock flag indicating whether or not PS-linked is SMS-Push is a value indicating that there is interlock (step S401). That is, the linkage flag is “no linkage” for the service A and “with linkage” for the service B.

When the interlock flag is a value indicating “with interlock”, it is further determined whether or not the permission flag indicating whether or not the distribution is permitted even when the line state is stopped is a content indicating “permit” (step) S401 → S402). When the permission flag indicates “permitted”, the packet from the communication terminal device is transmitted to the internal server 42 regardless of the line state (step S402 → 403). If the content does not indicate “permitted”, the packet is transmitted or the transmission is suppressed according to the line state (steps S402 → S404).
In step S401, if the interlock flag is a value indicating “no interlock”, PS transmission is performed or the transmission is restricted according to the PS standard (step S401 → S405).
By controlling as described above, it is possible to permit packet communication that is determined in advance, for example, when there is urgency without restricting the packet communication.

(Configuration example of communication terminal device 31)
Next, a configuration example of the communication terminal apparatus 31 that is the transmission destination of the SMS message will be described with reference to FIG. In the figure, a communication terminal device 31 receives an SMS message to which the above-described interlocking flag and permission flag are added, an SMS message receiving unit 311, and a packet in conjunction with the reception of the SMS message by the SMS message receiving unit 311. In the case of performing transmission, a packet transmission unit 312 that transmits a packet with an interlock flag and a permission flag added thereto is included. These units are functions realized by a CPU (not shown) executing a firmware or software program in the communication terminal device 31.

(Operation example of SMS message distribution system)
Returning to FIG. 1, an operation example of the SMS message delivery system will be described.
(S1) At the time of the SMS-Push instruction, the push server adds an interlock flag that is “PS transmission presence / absence information” and a permission flag that is “line suspension permission information” to the SMS message.
(S2) In the SMS incoming route, the following operations are performed in the devices in the network. When the linkage flag is “with linkage”, the process of confirming whether the user is in a state where PS transmission is possible is performed with reference to the contract status and APN status of the user of the destination communication terminal device. The contract state of the user of the destination communication terminal device can be referred to by making an inquiry to the HLR 200. Since an inquiry to the HLR 200 is a process that is normally performed when an SMS message is transmitted, information regarding the user's contract status is acquired at the time of the inquiry. Further, the status of the access point can be referred to by making an inquiry to the HLR 200.

As a result of the confirmation process, if the user is in a state where PS transmission is possible, an SMS message is transmitted. On the other hand, if the user is not in a state where PS transmission is possible, transmission of the SMS message is suppressed (transmission is restricted).
When the interlock flag is “no interlock”, the SMS message is delivered.
If “permitted” is set in the permission flag, transmission is continued even if the line state is not possible. On the other hand, when “non-permitted” is set in the permission flag, transmission of the SMS message is suppressed (transmission is restricted) when the line state is not possible. The interlock flag and the permission flag are transmitted to the communication terminal device 31 as they are together with the SMS message.

(S3) In the communication terminal apparatus 31 that has received the SMS message, PS transmission is activated according to the control content. At that time, the interlock flag and the permission flag notified by SMS incoming (added to the SMS message) are transparently set. That is, an interlock flag and a permission flag are added to the packet transmitted by PS.
(S4) On the PS transmission path, the following operations are performed in the devices in the network. When the interlock flag is “with interlock”, the permission flag is confirmed. When the permission flag is “permitted”, PS transmission is performed regardless of the contract state, the access point state, and the line state. On the other hand, when the permission flag is “non-permitted”, the PS transmission operation is performed based on the existing contract state, access point state, and line state.

(Confirming contract status and access point status)
Here, the confirmation process of the user's contract status, the confirmation process of the status of the access point, that is, the process of step S302 described above will be described. In the example described above, confirmation of the user's contract status and access point status is performed by the exchange 110 accessing the HLR 200. In addition, the confirmation process may be performed using the following method.
First, in FIG. 9, the confirmation of the contract status of the user is performed by the exchange 110 accessing the HLR 200 and referring to the contents in this example. That is, the contract information is referred to when accessing the HLR 200 from the exchange 110 in the existing destination inquiry process. If the information about the access point and its state is held in the HLR 200, the user's contract state and the state of the access point can be confirmed in the existing destination inquiry process.

  As a method of not changing the configuration of the HLR 200, as shown in FIG. 10, information on the state of the access point may be held in the operation system (OPS) 300 and referred to. The operation system 300 has a function of performing maintenance monitoring on devices in the core network. If information about the access point and its state is held in the operation system 300, the information can be referred to by accessing from the exchange 110. That is, in the case of FIG. 10, the user's contract status is confirmed with reference to the HLR 200, and the access point status is confirmed with reference to the operation system 300.

(Modification)
For the present invention, the following modifications can be considered.
(1) In the system described above, the case has been described in which the processing described with reference to FIG. 5 is performed in the exchange 110 in the core network 100.
You may perform the process in another apparatus. In short, an apparatus that relays the SMS message 101 may perform the process on the path from the push server 11 to the communication terminal apparatus 31.
(2) In the system described above, the case where the process described with reference to FIG. 7 is performed in the line / packet switch 120 in the core network 100 has been described, but the process may be performed in another apparatus. In short, a device that relays packets on the route from the communication terminal device 31 to the internal server 42 may perform the processing.

(3) The permission flag may be subdivided depending on how the line state is handled. In this case, it can be set separately as a plurality of flags. When a plurality of flags are used as the permission flag, each step is added in the processing flow described above. For example, a flag such as a line stop (forced stop or abolished provisional state) led by a communication company or a line stop (use upper limit exceeded state) due to the user's upper limit setting being exceeded can be considered.
(4) The interlock flag can be used as an identifier for determining the NW operation even in the SMS incoming route. That is, it is possible to adapt to the function based on the PS interlocking premise. On the other hand, the SMS message without PS linkage does not allow the operation of this function, and therefore this function can be avoided by this identifier.

(5) Although the above has described the case of communication terminal device lock and emergency call, the following can be considered as operations that should be able to be performed even when the usage upper limit is exceeded in addition to terminal lock and emergency call. That is, remote control for controlling a communication terminal device from a communication company, and a service that collects and uses a flat fee and does not charge each Push service are applicable.
(6) Although the above has described the case of the SMS message linked to the Push server operated by the communication company and the PS communication to the internal server, the PS communication to the external Push server and the external server operated by a company other than the communication company The present invention can be similarly applied to the case of an SMS message linked to the.

(SMS message delivery method)
In the SMS message delivery system described above, the following SMS message delivery method is realized. That is, an SMS message delivery method for relaying an SMS message from a transmission source device to a transmission destination communication terminal device, wherein the message is received at the transmission destination communication terminal device added to the SMS message In particular, when the interlock flag indicating whether or not the message is to perform packet communication in conjunction with the packet communication interlock, the user's contract status and access point status of the destination communication terminal device are displayed. An SMS message delivery method comprising: a confirmation processing step for performing confirmation processing for confirmation; and a transmission control step for performing either transmission processing or transmission suppression processing for the SMS message based on a confirmation result by the confirmation processing unit. Is realized. According to such an SMS message delivery method, contents such as “could not be connected” are not displayed on the screen of the communication terminal device.

The SMS message further includes a permission flag indicating whether or not the SMS message is a message for which packet communication is permitted, such as when the SMS message is urgent. In the control step,
When the permission flag added to the SMS message indicates packet communication permission, the SMS message is transmitted,
If the permission flag indicates packet communication non-permission, an SMS message that performs either a transmission process or a transmission suppression process for the SMS message according to the state of the communication line based on the confirmation result in the confirmation process step A delivery method is realized. According to such an SMS message delivery method, not all PS transmissions are restricted, but PS transmissions can be permitted for emergency transmissions and the like.

(Summary)
Conventionally, when the service B is provided, the status of the “contract status” or “access point” that determines the PS transmission operation is not confirmed at the SMS message delivery timing. For this reason, an operation difference between the SMS incoming call and the PS outgoing call is generated, and a content such as “could not be connected” is displayed on the screen of the communication terminal device, causing the user to be aware of service B. In addition, since there is no mechanism for transmitting the specified service policy (use the service even when the usage limit is exceeded) to the PS transmission process at the SMS message delivery timing, the operation difference between the incoming SMS message and the PS transmission is calculated. The specified service cannot be provided. In order to deal with these problems, it has been necessary to modify the devices constituting the network or to perform maintenance work to change the setting of the access point.

On the other hand, in the present invention, in order to avoid the difference from the PS transmission operation, the contract information or the like is confirmed at the timing of delivering the SMS message, and the SMS message is sent to the destination communication terminal device based on the confirmation result. Transmission or transmission suppression. As a result, it is possible to prevent the user from being aware of the service B under any PS transmission operating condition, and the user is not given an impression that a malfunction has occurred. In addition, since it is not necessary to modify the communication terminal device, the same operation can be realized by a terminal currently used and a terminal manufactured in the future.
In addition, the designated service can be provided under any PS transmission operation condition. In addition, the service B can be dynamically provided without modifying the devices constituting the network or performing maintenance work for changing the setting of the access point.
