Description

Method for automatically receiving SMS of SMS telephone for CID non-affilation}

The present invention relates to an automatic SMS receiving method of a non-subscription SMS phone, in particular, SMS automatic confirmation of SMS subscribers receiving SMS messages by checking the presence or absence of a CAS signal of an SMS received after a designated bell signal. It is about receiving method.

In general, as the industrial society develops, information communication systems are widely used to transfer data from one point to another desired more appropriately and quickly. Such communication systems are usually homogeneous or heterogeneous communication devices which are geographically dispersed. In most cases, information devices are connected to a network to enable sharing and communication of resources. In addition, in such a network, a telephone system is usually used through an exchange to exchange information converted into an electric signal with a counterpart.

However, the conventional telephone system as described above has a function of storing a short message service (SMS) recently transmitted from the caller when the user is absent, the caller's information, for example, the caller's telephone number or the date / time of the call and the like. It has a Calling Identity Delivery (CID) function that delivers information. In addition, the above CID information is modulated by a frequency shift scheme (FSK) through a CID modem to a telephone system and received after the first ring signal. The CID service is used after subscribing to the service provider.

Then, referring to the SMS telephone system subscribed to the conventional CID as described above with reference to FIG. 1, an exchanger 72 for exchanging a communication signal to the corresponding landline telephone 71 via the PSTN network 70 and the exchanger. It includes a PSMSC server (PSTN short message service center: 73) for providing the SMS signal received through the 72 to the wired telephone 71 using the CID function.

On the other hand, referring to the operation of the SMS phone system with the conventional CID function as described above, the SMS data is transferred to the PSMSC server 73 via the switch 1 in the usual manner when the SMS data is transmitted from the phone at a predetermined position. Is delivered to. In addition, the PSMSC server 73 checks the destination phone number of the received SMS data and inputs a ring signal to the TIP / RING terminal of the telephone 71 called through the switch 72, wherein the called The switch 72 connected to the telephone 71 carries the caller's CID information, that is, the telephone number of the caller's telephone 74 or the date / time of the call and other information between the first ring signal and the second ring signal. The wired telephone 71 is transmitted. At this time, the PSMSC server 73 connected to the exchange 72 transfers the server number of the PSMSC server 73 to the CID information.

Then, the wired telephone 71 receives the CID information input through the CID channel, displays it on the display (not shown), checks the server number included in the CID information, and then off-hooks the corresponding PSMSC server. The response signal is sent to (73).

Accordingly, the PSMSC server 73 checks the response signal input from the wired telephone 71 and transmits the SMS data to the wired telephone 71. The wired telephone 71 displays the SMS data provided from the PSMSC server 73 and stores the SMS data in the internal memory.

Here, if the subscriber of the landline telephone 71 wants to receive an SMS message in a CID non-subscribe state, if a ring signal is input, the subscriber of the landline telephone 71 manually turns off the handset of the landline telephone 71. Hook it up. Then, a call is formed between the landline telephone 71 and the PSMSC server 73 according to the off-hook signal of the wired telephone 71. In addition, the PSMSC server 73 transmits an SMS message using a currently formed call path, and accordingly, the wired telephone 71 displays the received SMS message to the outside.

However, the SMS phone system with the conventional CID function as described above is not a problem when the CID service is possible, but the CID non-subscribed phone is waiting for the user to receive an SMS message while the telephone line rings after the user rings. Because you need to manually make a call status (OFF-HOOK) and then receive an SMS message, if you are absent, you can't receive the SMS message because you can't know the server number even if the SMS message is sent to the terminal. In addition, even if the message is transmitted from the PSMSC server to the landline phone more than a certain number of times, there is a problem that the message is frequently lost when the landline phone does not receive the message.

Accordingly, the present invention has been invented to solve the conventional problems as described above, by checking the presence or absence of the CAS signal of the SMS received after the designated bell signal, by receiving the SMS message, SMS messages are easy to use even CID unsubscribed SMS phone It is an object of the present invention to provide an automatic SMS receiving method of the CD non-subscribed phone to significantly improve the functionality of the SMS phone accordingly can be received.

Another object of the present invention is to automatically off-hook the CD non-subscription SMS phone without any additional off-hook device, thereby receiving and processing SMS messages, thereby reducing the manufacturing cost of the SMS phone. An automatic reception method is provided.

In order to achieve the above object, the present invention provides an SMS automatic reception function setting step of setting an SMS automatic reception function including ring signal reception frequency designation in a CID-free wired telephone, and a user preset after the SMS automatic reception function setting step. When the ring signal is received by the user, the ring signal reception frequency check step of confirming whether the ring signal has been received as many times and the ring signal reception frequency check step is confirmed is automatically off-hook. An automatic call state switching step of switching to a call state, an SMS message input checking step of checking whether a CAS signal is included in a communication signal input through a PSTN network after the automatic call state switching step, and the SMS message input checking step If the CAS signal is detected among the communication signals input through the PSTN network, the system recognizes this as SMS message reception mode and It provides an automatic SMS receiving method of the SMS non-subscribe SMS phone consisting of the SMS message receiving step of receiving the SMS message transmitted through the N network.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The CID non-subscribed telephone 1 to which the present invention is applied receives a CAS (CPE Alerting signal) signal transmitted from the PSMSC server 9 connected to the exchange 3 via the PSTN network 2, as shown in FIG. Including the interface unit 4 for interfacing the call signal of the external caller, and the presence or absence of the CAS signal received through the interface unit 4 to perform the SMS message receiving function and the overall function of the phone 1 A microcomputer 5 for controlling and a memory unit 6 for storing short messages (SMS) input in the absence of a user through the interface unit 4 according to a function control signal of the microcomputer 5; And an LCD 7 for reproducing the short message signal of 6) as a display signal.

One end of the microcomputer 5 is connected to a keypad 8 for inputting a user's control command signal or dialing signal.

Next, the method of the present invention applied to such a telephone will be described.

First, the method of the present invention proceeds to the SMS automatic receiving function setting step (S2) in the initial state (S1) as shown in Figure 3 to set the SMS automatic receiving function including the ring signal reception frequency specified in the CID unsubscribed landline telephone do. After the SMS automatic receiving function setting step S2, the ring signal count determining step S3 is performed to determine whether the ring signal has been received a predetermined number of times. In addition, when the ring signal is not input for the preset number of times as a result of the determination in the ring signal number determining step (S3), it is determined that the other mode function is terminated. However, if the ring signal is input as many times as the preset number of times, as determined by the ring signal frequency determination step (S3), the process proceeds to the automatic call state switching step (S4) and automatically switches off to the call state. . After the automatic call state switching step S4, the SMS message input judging step S5 is performed to determine whether the CAS signal is included in the communication signal input through the PSTN network. At this time, if the CAS signal is not detected in the communication signal input through the PSTN network as a result of the determination during the SMS message input determination step (S5), it is determined that the automatic response mode and proceeds to the automatic response function execution step (S6) and set the automatic response. Run the function.

However, if the CAS signal is detected in the communication signal input through the PSTN network as a result of the determination in the SMS message input determination step (S5), it is determined as the SMS message reception mode and proceeds to the SMS message reception step (S7) to the PSTN network. Receive SMS messages sent via After the SMS message receiving step (S7), the display proceeds to the receiving message display step (S8) to display and store the currently received SMS message.

That is, when the user wants to receive an SMS message in the CID non-subscribed landline phone 1 as described above, the SMS automatic reception function is set. In this case, the user of the landline phone 1 uses the keypad 8. By inputting the number of the ring signal to recognize his absence through. Then, the microcomputer 5 of the wireline telephone 1 stores the number of ring signals input by the user in the memory unit 6 and switches to the standby mode.

Here, if a communication signal, for example, a ring signal, is input from the external switch 3 connected to the wireline telephone 1 through the PSTN network, the microcomputer 5 receives it through the interface unit 4 and checks the number of times. Done. At this time, the microcomputer 5 executes the normal call mode when the number of times of reception of the currently input ring signal is received within the number specified by the user, that is, when the user lifts the handset.

However, if the ring signal inputted through the PSTN network 2 rings more than the number of times set by the user, the microcomputer 5 switches to the automatic call state by off-hooking and then the PSMSC server 9 Check if the CAS signal provided from) is detected.

Here, if there is no CAS signal among the signals currently input, the microcomputer 5 proceeds to the user missed mode and transmits the missed guide message stored in the memory unit 6 to the counterpart phone 1 in advance. And, if there is a voice message from the counterpart phone 1, the microcomputer 5 of the phone 1 receives this message through the interface unit 4 and stores it in the memory unit 6.

However, when it is confirmed that there is a CAS signal among the signals currently input during the CAS signal checking process, the microcomputer 5 switches to the SMS message receiving mode and receives the SMS message from the PSMSC server 9 through the exchange 3. . Then, the microcomputer 5 displays the received SMS message to the outside through the LCD 7 and stores the received SMS message in the memory unit 6.

Therefore, according to the method of the present invention as described above, even if the CID-unsubscribed phone does not know the server number of the PSMSC server, it automatically off-hooks using the ring signal through the same process and then receives the SMS message using the CAS signal. do.

As described above, according to the present invention, the SMS message can be easily received even by a CID-unsubscribed SMS phone by confirming the presence or absence of a CAS signal of the SMS received after a designated bell signal. It has the advantage of significantly improving its functionality.

In addition, according to the present invention, since the non-subsidiary SMS phone automatically off-hook without additional off-hook device to receive and process SMS messages, there is also an effect of significantly reducing the manufacturing cost of the SMS phone.
