The present invention relates to a home phone (Home Phone) used in the home automation system (H.A), and more particularly, to a method of connecting to a call that automatically connects to the corresponding call source when there is one call source.

The home phone used in the conventional home automation system (H. A: Home Automation System) is a call source by selecting a call source with a selection button depending on the call source.

1 is an external view showing a general telephone having a function of indicating a call source. In FIG. 1, 'K1' indicates that the call source is a CO line by flashing a lamp with a ring tone when the call is from a CO line, and when pressed, the telephone is connected to the CO line. 'K2' is a ring tone when the call is from an extension. The lamp flashes with indicating that the call source is an extension, and pressing it connects the phone to the extension. The extension here refers to being connected to other telephones (ie home phones) rather than through a public telephone network.

'K3' flashes with a ringtone when the call is from a guard phone, indicating that the call source is the guard's phone, and when pressed, the phone is connected to the guard's room. The lamp flashed to indicate that the call source was a phone, and when pressed, the phone was connected to the door phone. In other words, when the visitor comes to press the doorbell, the bell rings and the door selection button blinks. At this time, the user may press the door selection button K4 to speak with the visitor. In addition, when a call was received from the outside through the public telephone network, when the CO line selection button (K1) was pressed by flashing the CO line selection button (K1) LED with a ring tone, it was possible to make a call with the outside.

By the way, such a regular phone was very inconvenient because it had to press the select button (K1 ~ K4) even when a call from any one call source. That is, from the user's point of view, even though only one call source from the outside does not have to press the select button separately, the select buttons K1 to K4 are always pressed.

Accordingly, an object of the present invention is to provide a method for connecting a call in a home automation system that automatically connects a handset without pressing when a call is received from a single call source in order to solve the conventional problems as described above.

In order to achieve the above object, the method of the present invention provides a method for connecting a call to an external call source connected through a network controller and an internal call source connected to a home bus to a home phone.

A lake new step of notifying visually when a call is received from the call sources;

An internal call source connection step of connecting the internal call source to the home phone by requesting a channel assignment to the network controller if the call source is one and the internal call source; And when the call source is one and the external call source, the network controller selects the corresponding external call source and connects the external call source to the home phone through channel assignment.

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

As the standardization work on the home automation system progresses, the specification of the home information bus (called the home bus) is EIAK CE-3004, the specification of the communication equipment service of HIBus is EIAK CE-3005, and the AV equipment service of HIBus. The standard for EIAK CE-3006 and HIBus for home appliance service have been established for EIAK CE-3007.

In FIG. 2, a network controller (NCU: Nwtwork Control Unit: 10) is a device that is the center of a home information bus (HIBus). The system initialization, terminal property management, telephone line and information channel management / allocation, and information It performs functions such as notification of channel usage status. In addition, a telephone line (called a trunk line) is connected from a public telephone network, a guard telephone is connected from a guard room, and an external door phone is connected to each terminal through a home bus. In addition, when the terminal requests the information channel allocation, the terminal allocates the information channel based on the information channel usage.

The home bus (HIBus) is divided into an information channel and a control channel, and is implemented as a twisted pair cable (TP). The information channel can accommodate up to three channels and transmit information such as voice, long data, and video. The control channel transmits simple information such as commands to monitor the control and status of devices connected to the home bus (HIBus). The digital signal transmitted on such a home bus is usually an AMI signal.

The first home phone and the second home phone 30-1 and 30-2 are home bus-compatible products, which are connected to the home bus HIBus and connected to the public telephone network through the network controller 10, respectively. In addition, the first home phone (second home phone) is connected to the second home phone (first home phone) through the information channel has an extension function that can directly talk. In addition, the first and second home phones 30-1 and 30-2 are automatically connected to the call source by lifting the handset (hook-off) when the call source is one according to the present invention. There is no need to press and hold the call source selection switch.

The video door phone 20 can check the identity of the visitor by making a call while viewing the screen with the visitor through an external door phone (not shown) connected to the network controller 10.

FIG. 3 is a detailed block diagram of the network controller shown in FIG. The network controller 10 crosses a trunk line interface unit 11 for connecting with a trunk line, a door phone interface unit 12 for connecting with an external door phone, and a guard phone interface unit 13 for connecting with a telephone of a guard room. It is connected to the point switch 14, respectively. The cross point switch 14 connects one of the interface units 11, 12, 13 to the bus interface unit 15 under the control of the microcomputer 16, and the bus interface unit 15 is connected to the microcomputer 16 of the microcomputer 16. Connect to one information channel under control. That is, the home bus HIBus is divided into the control channel CH1 and the three information channels CH2 to CH4, and the specific information channels CH2 to CH4 allocated according to the channel allocation procedure through the control channel CH1. Connect your home phone with an external phone.

4 is a block diagram showing the home phone shown in FIG. The home phones 30-1 and 30-2 are connected to a home bus interface unit 31 connected to a home bus HIBus, a reception processor 32 processing a received signal, and the received contents under the control of the microcomputer 38. A display unit 33 for displaying, a speaker 34 for notifying the received contents by sound, a handset 35 for allowing the handset to listen to the output of the reception processor 32, a transmitter 37, a transmission processor 30, The microcomputer 38 and the key input device 39 are provided. The operation of the home phone having such a configuration will be described in detail according to the flowcharts shown in FIGS. 5 and 6.

The home phones 30-1 and 30-2 monitor whether a call is received from a call source (COD, extension line, security phone, door phone, etc.), and when the call is received (51), sets the corresponding source bit in the register. (52). The source of the call is displayed on the LCD of the home phone (53), and the phone rings to notify the user that a call has been received and the corresponding LED blinks (54). Therefore, a person near the home phone recognizes the call and picks up the handset (hook-off) for the call.

6 is a flowchart showing a call operation of the home phone shown in FIG.

After ringing to announce that a call has been made, monitor whether the hook is off (61). When the 'hook is off', it checks whether the source of the call is one, and if it is one, automatically selects and connects the call source according to the present invention (62), and if not, the source selection key (K1 ~ K4). ) Is entered (68). When the call source selection key is input, first, if there is a call source connected, it transmits a pending sound to the currently connected call source (69, 70). Next, the selected call source is connected to the call channel (71). If there is only one call source, it is determined whether it is an extension (63). If it is an extension, the network controller requests an information channel (64), and connects the calling home phone with a call path (65). If not, the cross point switch of the network controller is connected to the corresponding source (66), and the information channel is allocated to connect the external call source and the home phone (67). When the call ends, the user releases the handset (hook-on).

Thus, if the 'hook-on' is monitored (72), if the 'hook-on', the cross-point switch is disconnected (73), the information channel is opened (74).

As described above, when there is only one call source according to the present invention, it is convenient to use the handset by automatically connecting the corresponding call source.
