Abstract

PURPOSE:To identify easily that a connected device is a terminal device transferred during communication by providing a function a high resistance termination at transfer during communication to an incoming information connecting line of a subscriber's terminal equipment. CONSTITUTION:In transferring the subscriber's terminal equipment 7 during the communication state already, a couple of the incoming information connection lines are terminated by a high resistance resistor 9 by operating a changeover switch 8 at the inside of the subscriber's terminal equipment 7. Since other subscriber's terminal equipments plugged to a socket 4 are not terminated by the high resistance resistor 9 for a couple of the incoming information connecting lines because the communication is started newly during the transfer of the subscriber's terminal equipment 7, it is identified that the connection is not the reconnection of the subscriber's terminal equipment 7 transferred during communication, and when the subscriber's terminal equipment 7 transferred during communication is plugged to the socket 4, since a couple of the incoming information lines are terminated by the high resistance 9, a digital exchange 1 detects the termination by the said high resistance resistor 9.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an in-home terminal device for a digital subscriber line connected to a digital subscriber line exchange, and more particularly to a movement detection method for the in-home terminal device for detecting movement of the in-home terminal device.

2. Description of the Related Art Conventionally, as a digital subscriber's home equipment connected to a digital exchange, a home line termination device and a plurality of home terminal devices may be connected to a set of subscriber lines.

In this case, the number of in-home terminal devices that can communicate at the same time is only one, and the in-home terminal device to be used for communication is selected and used by the line switching function in the in-home line termination device.

Therefore, even if multiple home terminal devices are connected to one set of subscriber lines, the number of home terminal devices that are communicating at the same time is l, and when the socket of the home terminal device that is currently communicating is unplugged and the terminal is moved. However, even if another home terminal starts communication, it is impossible to determine whether the home terminal is moving or newly starting communication. Furthermore, although a digital subscriber system in which a plurality of in-home terminal devices can communicate at the same time is technically possible, the above-mentioned drawbacks also arise.

The purpose of the present invention is to provide a function in the home terminal device to terminate the information connection line connecting the home circuit terminal device with high resistance so that the home terminal device can be moved during communication. When you pull out the socket and connect it to another socket,
The object of the present invention is to provide a movement detection method for a home terminal device that can easily identify that a connected device is a mobile terminal during communication.

The movement detection method of the in-home terminal device of the present invention is applied to a digital subscriber line exchange. - in a digital subscriber line connected to a digital subscriber line, an in-home line termination device installed inside the house that terminates the Digimol subscriber line and performs a synchronization function; and a plurality of sockets connected to the in-home line termination device; It has a socket that plugs into the socket, and has two pairs of information, one in the direction from the home terminal device to the home line termination device (hereinafter referred to as upper side) and the other direction from the home line termination device to the home terminal device (hereinafter referred to as downlink). It is characterized by comprising an in-home terminal device having means for terminating the uplink information connection line of the connection line with a high resistance.

Next, embodiments of the present invention will be described with reference to the drawings.

Figure 1 shows an example of the movement detection method of the in-home terminal device of the present invention.
An example is shown (p diagram).Digital subscriber line exchange l
, a digital subscriber line 2, a home line p, 4, pH4 device 3, a plurality of sockets 4, a plug socket 5, two pairs of information connection lines 6 in both up and down directions 9, and a home terminal device 7.
It is composed of a selector switch 8 and a high resistance 9.

The operation of the movement detection method of the in-home terminal device configured as described above will be explained. Digital subscriber can communicate with multiple home terminals at the same time.
In the subscriber system<f4 configuration to which θ゛ is connected, the subscriber line signaling system between the home terminal device β'7 and the digital subscriber line exchange 1 is layer 41, for example, Layer 1 stipulates the electrical and physical conditions, Layer 2 is the link layer protocol, and Layer 3 is the network layer protocol '(f'').The subscription name number assigned to the digital subscriber line is the network layer number. The terminal identifier number in the layer 2 address field is assigned to each individual home terminal device. The terminal identifier number is assigned to each in-home terminal device 7 when the plug socket 5 of the in-home terminal device 7 is inserted into the socket 4 and synchronization of the link layer is established.
will be allocated to. When a call is connected between the home terminal device 7 and the digital subscriber line exchange l, the call connection information is sent and received using the RAY 73 function, with layer 2 formats such as address fields added on the digital subscriber line. be done.

When moving an in-home terminal device that is currently communicating, the RAY 73 functions of the in-home terminal device 7 and the digital subscriber line exchange 1 exchange information in advance to indicate that the in-home terminal device 7 will transition to a moving state during a call. I remember. When the home terminal device #7 is inserted into another socket 4 after being moved, link synchronization of the digital subscriber line 2 is newly established at that point. The terminal identifier number in the address field of the terminal is assigned. However, from the perspective of the digital exchange 1, while the corresponding home terminal device 7 is moving, another home terminal device may be inserted into the socket 4, link synchronization may be established, and a terminal identifier number may be assigned. When moving the home terminal device 7 that is already in communication, the high resistance 9 is terminated between the pair of upper information connection lines using the changeover switch 8 inside the home terminal device 7. Perform operations. As a result, when another home terminal device is inserted into the socket 4 to start a new communication while the home terminal device 7 is moving, unless the pair of upper information connection lines is terminated with the high resistance 9, It cannot be identified unless the mobile home terminal device 7 is reconnected during communication, and when the mobile home terminal device 7 is inserted into the socket 4, there is a high resistance between the pair of upper information connection lines. 9, the digital converter 1 detects the termination at the nuclear high resistance 9, thereby identifying that the home terminal device 7 plugged into the socket 4 is reconnected due to movement during a call. Therefore, the digital exchange 1 adds a new terminal identifier number in the RAYA address field to the reconnected home terminal device 7, and can transmit and receive information on RAY 73 and above with the reconnected home terminal device.

As explained above, in an in-home system configuration in which a plurality of in-home terminal devices are connected to one in-home line termination device via sockets, the present invention provides a high level By providing a resistance termination function, when each in-home terminal device moves during communication, the digital subscriber line exchange detects the high resistance termination of the reconnected in-home terminal device, thereby terminating the digital subscriber line. After establishing link synchronization of the reconnected in-home terminal equipment, the exchange can identify whether the in-home terminal equipment is moving during communication using the layer, and the in-home terminal equipment and the digital subscriber line exchange are reconnected. After that, there is an effect that the information exchange operation can be immediately shifted to the original information exchange operation of a higher layer higher than the layer 73.
