Phone and Method Being able to download data to Far Point}

FIELD OF THE INVENTION The present invention relates to a telephone, and more particularly to a telephone that enables a telephone user to download the received SMS or Caller ID data remotely from the telephone that has received the SMS or Caller ID data when the telephone user is traveling or away from the office. And a download method.

In general, a telephone is a communication terminal that has traditionally been developed to receive text data, as well as to receive text data.

That is, voice and text data transmitted from the switching device through the telephone network, which is the transmission device, are received by the telephone, which is the terminal device.

Among the text data that can be received by the phone, the short message service (Short Message Service, also referred to as 'SMS') and the caller information display (Calling Identity Deliverty, also referred to as 'CID' or 'Caller ID') have.

First, the short message service (SMS) is prepared as a short message according to a communication protocol set by an SMS server and transmitted to the terminal of the user. The SMS server transmits a short message to a telephone through a public switched telephone network (also referred to as a 'PSTN') and, in the case of a wireless SMS server, also transmits a short message to a telephone through a wireless network. . In addition, the short message may be composed of a length of about 160 characters.

When the short message is received by the phone as the terminal as described above, the short message is processed and automatically stored according to the general short message receiving procedure of the terminal.

On the other hand, the caller information display is transmitted to the terminal through the network communication network (public telephone network or wireless network) connecting the user terminal and the operator side of the operator by the Caller ID server, similarly to the SMS. That is, the Caller ID server recognizes the unique identification number of the user terminal connected to the operator side of the operator and transmits the Caller ID data to the user terminal through the network communication network.

Caller ID data received by the terminal is automatically stored in the storage device, and displayed on the display unit under the control of the control device so that the caller's telephone number is known.

Therefore, when the caller transmits the short message or the calling number, the SMS server and the Caller ID server receive the short message and the calling number through a network and transmit the received short message and caller ID to the terminal, and the terminal transmits the short message data and the Caller ID data. Receive and save.

As described above, the short message data and the caller ID data stored in the terminal are later retrieved by the user and stored through the display unit.

However, a phone capable of receiving SMS data and Caller ID data according to the prior art as described above poses the following problems.

That is, in order to retrieve and read SMS data or Caller ID data stored in the phone, the playback device in the phone must be used. Therefore, when the user is remote from the phone, a problem arises in that the user cannot reproduce and read SMS data or Caller ID data stored in the phone.

And in order for a remote user to read SMS data or Caller ID data stored on the phone, he or she must go directly to the location where the phone is located or read it, or read it from another person (eg, family or secretary). .

The present invention is to solve the problems of the prior art as described above has the following object.

In a phone capable of receiving SMS data or Caller ID data, in addition to reading data by directly playing the stored SMS data or Caller ID data on the phone, the phone can download and play data stored in the phone remotely. To provide a telephone.

The following describes in detail an embodiment of the present invention on the basis of the accompanying drawings.

1 is a block diagram and a network block diagram of a phone capable of downloading text data remotely according to the present invention.

As shown in Fig. 1, an exchange 110 performing an exchange function is located as one component of a communication network. The exchange 110 is networked with the telephone 120 by the public telephone network 100.

The message center 112 is connected to the exchange 110. The message center 112 is an SMS center or a Caller ID center.

The caller ID center, which is the message center, recognizes caller information (telephone number and name) of the caller terminal (not shown) and sends caller ID data (ie, caller phone number) to the receiver terminal 120 through the public telephone network 100. And statement).

The SMS data, which is the message center, recognizes and stores a short message received from a sender terminal (not shown) and transmits the short message to the receiver terminal 120 through the public telephone network 100.

The remote terminal 142 is network-connected to the exchange 110. The remote terminal 142 is a case of a wireless terminal as shown in FIG. 1, but is not limited thereto, and may be a wired terminal.

In the case where the remote terminal 142 is a wireless terminal as in the present embodiment shown in FIG. 1, a gateway device that is a protocol conversion device because the communication protocol between the wireless data network 140 and the public telephone network 100 is different (not shown) O) is required.

In addition, when the remote terminal 142 is a wired terminal (not shown), the gateway device is not necessary because the communication protocol is the same by using a public telephone network which is the same communication network as the receiver terminal 120.

The following describes the configuration of the telephone 120 which is the receiver terminal.

The interface unit 122 is connected to the public telephone network 100. The interface unit 122 interfaces a data signal input through the public telephone network 100.

In addition, the detection unit 128 is connected to the interface unit 122. The detector 128 detects a transmission reserve signal included in the data signal received through the interface unit 122.

That is, when the data received through the interface unit 122 is Caller ID data, the detection unit 128 is composed of a ring detector (Ring Detecter) and the transmission reserve signal is a ring signal.

When the data received through the interface unit 122 is SMS data, the detection unit 128 is a LIU detector when a call is waiting, and a CAS detector (Channel Associated Signaling Detecter) when a call is in progress.

The control unit 124 is connected to the detection unit 128. The control unit 124 determines the transmission reserve signal detected by the detection unit 128 and controls the SMS data or Caller ID data to be transmitted to the data processing unit 129. The control unit 124 also controls the SMS data or Caller ID data stored in the storage unit 126 to be downloaded to the remote terminal. In addition, the control unit 124 is implemented by a central process unit (CPU).

The data processor 129 is connected to the controller 124. The data processing unit 129 modulates SMS data or Caller ID data input to the interface unit 122 by frequency shift keying (hereinafter referred to as 'FSK') under the control of the control unit 124. .

The control unit 124 is further connected with a storage unit 126. The storage unit 126 stores SMS data or Caller ID data modulated by the data processing unit 129 under the control of the control unit 124.

In addition, components other than the components of the telephone 120, for example, a keypad unit, an LCD display unit, and the like are the same as known, and thus description thereof will be omitted.

The following describes a process of downloading data from a data downloadable telephone remotely having the above configuration.

The SMS center or Caller ID center, which is the message center 112 that has received SMS data or Caller ID data transmitted from a sender side terminal (not shown), transmits the SMS data or Caller ID data through the public telephone network 100. The phone 120 transmits.

SMS data or Caller ID data input through the public telephone network 100 are interfaced while passing through the interface unit 120 (step 210).

A process in which the Caller ID data is detected by the phone 120 will be described. First, the caller ID data signal is carried on the next signal of the first ring signal coming from the switchboard 110 through the public telephone network 100.

The Caller ID data signal carried on the next ring of the first ring signal is detected by a ring detector which is a detection device, and the ring detector transmits the detected signal to the controller 124. The control unit 124 receiving the detection signal controls the caller ID data to be input to the data processing unit 129 through the interface unit 122.

On the other hand, in case of SMS data, the LIU detector determines whether or not the telephone 120 is in a call, and when the call is waiting, the control unit 124 controls the signal to be transmitted to the data processing unit 129 via the interface unit 122. .

When the call is in progress, the CAS detector interworkes to transmit a busy signal to the exchange 110, and the exchange 110 transmits a CAS signal to the controller 124. The controller 124 receiving the CAS signal controls the SMS data signal to be input to the data processor 129 by blocking a voice call.

As described above, the SMS data or the Caller ID data input to the data processor 129 becomes a data signal demodulated by FSK demodulation of the data processor 129.

As described above, the SMS data or the Caller ID data demodulated by the data processing unit 129 is retrieved by the control of the control unit 124 and stored in the storage unit 126 (step 212).

In order to download the stored SMS data or Caller ID data in the above process, the remote user calls his / her phone 120. At this time, the terminal used by the remote user at the remote location may be a wired telephone or a wireless telephone as described above (step 214).

As described above, when the remote user calls the telephone 120 by the remote terminal 142, the telephone 120 rings for a predetermined time (a predetermined time set in the control unit 124, for example, 20 seconds). When the predetermined time elapses, the voice message service is provided by digital signal processing (DSP).

The voice message service may be, for example, number 1 of a sender's voice and number 2 of a remote download (step 216).

Among the voice message service by the DSP, the remote user selects a remote download function, 2 in the example (step 220).

If the remote user selects the remote download function, the process proceeds to determining whether the user is authenticated. That is, the remote user inputs a unique number for downloading the SMS data or the Caller ID data stored in the storage unit 126 (step 220).

Then, the controller 124 determines whether the input unique number data and the unique number already set in the controller 124 match. If the unique number input by the remote user does not match the set unique number, the next step for downloading does not proceed, and the unique number must be input again, and if it matches, the process proceeds to the next step (step 222).

If the unique number input by the remote user matches the unique number set in the controller 124, the user selects SMS data or Caller ID data in the next step (step 224).

If the remote user selects either SMS data or Caller ID data, for example, SMS data, the voice message service by the DSP goes to the next step of inputting the remote terminal telephone number. The remote terminal telephone number is the number of the terminal to which the SMS data or the Caller ID data is to be downloaded (step 226).

When the remote user enters the telephone number of the remote terminal and waits for a call, the selected SMS data is transmitted from the phone 100 to the remote terminal 142.

The process of transmitting the SMS data selected from the phone 100 to the remote terminal 142 will be described in detail. First, the remote terminal number input in step 226 is interfaced through the public telephone network 100 and the interface unit 122 and then stored in the storage unit 126.

The remote terminal number stored in the storage unit 126 is recognized by the control unit 124 as a terminal number to which SMS data or Caller ID data is to be transmitted, and the SMS data or Caller ID data under the control of the control unit 124. Is transmitted to the remote terminal 142 via the public telephone network 100 (step 228).

The remote terminal 142 receiving the SMS data or the Caller ID data as described above is stored in the storage device under the control of the CPU provided in the terminal itself. As described above, the SMS data or the Caller ID data stored in the storage device of the remote terminal 142 can be read by the user through the playback process.

The regeneration process is already well known in the art, detailed description thereof will be omitted.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.

The data downloadable telephone and the data download method at a remote location according to the present invention having the configuration and operation process as described above are expected to have the following effects.

First, by implementing a data download function on a phone capable of receiving SMS data or Caller ID data, the SMS data or Caller ID data received on the phone can be confirmed by downloading the SMS data or Caller ID data received on the phone from a remote location. .

In addition, since the user can check the SMS data or Caller ID data stored in the phone even at a remote location, it is also expected that the manpower to receive and report the call becomes unnecessary.
