The network 400 represents a network connecting the home gateway 200 and the premises management server 300 to transmit data, for example, a public switched telephone network (PSTN), a broadband convergence network (BcN), or a wireless communication network. This corresponds to this. The network 400 may be composed of at least one exchange and a transmission path, and the home gateway 200 and the premises management server 300 are interconnected through an exchange through a transmission path. Since the network 400 is a known network configuration, detailed description thereof will be omitted.

Hereinafter, the system abnormality checking function of the remote living tool control system according to the first embodiment of the present invention will be described. Here, "system abnormality" is a concept including "network damage (disruption, etc.)" and "fault", and "network damage" means disconnection of a transmission path connecting the home gateway 200 and the exchange of the network 400. Such as, if the network 400 is a failure of the communication between the home gateway 200 and the premises management server 300, and "failure" refers to the case where the home gateway 200 is broken.

The system abnormality check function of the remote living tool control system according to the first embodiment is performed by the premises management server 300 in a non-billing manner in which the home gateway 200 periodically does not form a call path. Hereinafter, a case where the home gateway 200 and the premises management server 300 are connected through the network 400 including one exchange is described as an example, and the scope of the present invention is not limited thereto.

When the premises management server 300 transmits to the home gateway 200 every set period, the network 400, that is, the exchange of the network 400 sends a call signal to the home gateway 200, the premises management server 300 Transmits a ring tone.

Here, the "call signal" refers to a signal transmitted from the exchange to the called terminal device so that the called terminal device emits a ring tone. Calling Identity Delivery (CID) data is inserted between the call signals, so that the home gateway 200 can confirm that the received call signal is a call signal generated by the premises management server 300. In addition, the "call tone" refers to a signal sent by the exchange of the network 400 to the calling terminal, and in the case of disconnection of the called party, the call is mechanically transmitted to the calling party, and includes a user-specified tone.

"Setting cycle" is a system abnormality check cycle, and refers to a transmission cycle, that is, a call signal cycle, which is set for transmitting a call signal, and can be freely set in the premises management server 300, and the setting cycle is performed through the network 400. It may be transmitted to the home gateway 200.

The home gateway 200 determines whether the call signal is sent by the origin management server 300 through the CID data located between the first call signal and the second call signal, and the call signal is the premises management server 300. If it is not sent by the call of), it continues to be on-hook and does not construct a channel. Here, the "on-hook state" refers to a state in which the handset is put down, and since no call path is configured, charging is not performed.

If it is determined that the call signal is transmitted by the origin management server 300 through the CID data, the home gateway 200 is in an on-hook state until the number of received call signals reaches the reference call signal number. In this case, the call signal after the reference call signal number is switched to the off-hook state to form a call path. Here, the "off-hook state" refers to a state in which a handset is lifted, and a call path is configured to transmit and receive data and to charge.

"Reference call signal number" refers to the reference number set by the user, which allows the home gateway 200 to distinguish whether the call signal generated by the origination management server 300 is a system abnormality check signal or a valid data transmission signal. That is, it is set to the number of times that the calling party to secure the time to receive the first ring tone, it is preferably set to one to two times.

If the reference call signal count is set to two times, the home gateway 200 remains on-hook until the second call signal is received, and the home gateway 200 is in an off-hook state for subsequent call signals. Is switched.

While the home gateway 200 receives the call signal up to the first or second call signal, the premises management server 300 receives the first call tone from the exchange, and immediately on-hook upon receiving the first call tone, the home gateway The transmission of the call signal is no longer made by stopping the transmission to the 200. Accordingly, since the home gateway 200 receives only the second call signal, the home gateway 200 is kept in the on-hook state, and since the call signals exceeding the reference call signal number are not received, the home management server 300 Determine that the call is for system fault check and perform the following procedure.

The home gateway 200 induces a response call signal for notifying the premises management server 300 that it is not a failure or that the transmission path between the home gateway 200 and the exchange is not disconnected. That is, the home gateway 200 transmits the response call signal to the premises management server 300 by transmitting to the premises management server 300, and the exchange transmits the response call signal to the premises management server 300. The home gateway 200 transmits a ring tone.

When the premises management server 300 waiting for the response call signal after stopping the call to the home gateway 200 receives the response call signal, the transmission path between the home gateway 200 and the exchange is not disconnected or the home gateway It is determined that 200 is not broken. On the other hand, the home gateway 200 is switched to the on-hook state when the first ring tone is received from the exchange.

If the transmission path between the home gateway 200 and the exchange is disconnected or the home gateway 200 is broken, the home gateway 200 does not receive the call signal sent by the origin management server 300. , The response call signal can not be transmitted to the premises management server (300). That is, if the premises management server 300 guides the system error check call signal to be sent, if it does not receive the response call signal, it is determined that the state is abnormal, and accordingly, the message transmitting unit 310 of the user's mobile phone 500 Send a system fault message to the server to induce recovery by the user. This state is also stored in the data management unit 320 as a record.

If the premises management server 300 is sent to the home gateway 200 for the system abnormality check or data transmission, but in a busy state (that is, a state of receiving a busy sound, a busy sound, etc. from the exchange), after setting wait time Resend the call signal to the home gateway 200 for a predetermined time and resend the call signal, and if the busy state is repeated more than a certain number of times, the message transmitting unit 310 transmits a busy message to the user's mobile phone 500, Induce confirmation by the user.

When the premises management server 300 wants to transmit data to the home gateway 200, the home gateway 200 transmits a call signal by sending to the home gateway 200, and the call signal is transmitted to the home gateway 200. Even if a ringing tone is received, the off-hook state is maintained and the call signal is not stopped. Accordingly, the home gateway 200 receives the call signal more than two times the reference call signal number, and is switched to the off-hook state to form a call path and receive data from the premises management server 300. Examples of data received include A / S-related information such as equipment failure inquiries, control data (various setting cycles, user authentication data such as user ID and password and home gateway authentication data, etc.) and information related to downloading control data. Can be.

Hereinafter will be described a remote living tool control system according to a second embodiment of the present invention.

The setting period may be freely set in the home gateway 200, and the setting period may be transmitted to the premises management server 300 through the network 400. In addition, the setting period may be downloaded from the premises management server 300 to the home gateway 200 through the network 400.

The premises management server 300 determines whether the call signal is sent by the home gateway 200 through the CID data located between the first call signal and the second call signal, and the call signal is the home gateway 200. If it is not sent by the origination of, it continues to be on-hook and no further processing is done.

If it is determined that the call signal is transmitted by the origination of the home gateway 200 through the CID data, the premises management server 300 is in the on-hook state until the number of received call signals reaches the number of reference call signals. In this case, the call signal after the reference call signal number is switched to the off-hook state to form a call path.

If the reference call signal number is set to 2 times, the premises management server 300 maintains the on-hook state until the second call signal is received, and the off-hook state for subsequent call signals. Is switched to.

While the premises management server 300 receives the call signal up to the first or second call signal, the home gateway 200 receives the first call tone from the exchange, and immediately on-hook upon receiving the first call tone, the premises management The transmission of the call signal is no longer made by stopping transmission to the server 300. Accordingly, since the premises management server 300 only receives up to the second call signal, the on-hook state is maintained continuously, and since the call signals exceeding the reference call signal number are not received, the home gateway 200 is connected to the home gateway 200. It is determined that outgoing call is for system abnormality check.

In addition, since the premises management server 300 has received the call signal from the home gateway 200, it is determined that the network 400 is not disconnected, and that the home gateway 200 is not broken, this state is the data management unit 320 Are stored as records.

If the transmission path between the home gateway 200 and the exchange is disconnected or the home gateway 200 is broken, the premises management server 300 sends out the home gateway 200 by the transmission of the home gateway 200 even after a set period has elapsed. Since the call signal is not received, it is determined that the state of the system abnormality, and thus the message transmission unit 310 transmits the system abnormal message to the user's mobile phone 500, thereby inducing a recovery by the user. This state is also stored in the data management unit 320 as a record.
