Abstract

PURPOSE: A ring pick up method using a centric function is provided to offer a service efficiently by receiving a call instead of a member on the occasion of an absence of the member belonging to an RPU(Ring Pick Up) group. CONSTITUTION: An optional subscriber performs a hook-off in order to receive a call of a busy subscriber(208). A line control senses a hook-off signal, and reports a hook-off state and a ring state to a centric line control part in order to receive the call. It is decided whether a terminal performing the hook-off and a busy terminal belong to a same RPU(Ring Pick Up) group(212) or not. If the terminal performing the hook-off and the busy terminal belong to the same RPU group, the busy subscriber's data stored at an RPU buffer is deleted(216). A ring signal of the subscriber to which an in-coming call is demanded is cut off(218). A terminal of a subscriber inputting an RPU code is connected to a terminal of an out-going subscriber(220).

Description

Ring pick-up method using the Centrix function

The present invention relates to a ring pick up (RPU) service method using the Centrix function, and in particular, an extension subscriber in a ring when an originating subscriber requests a call to any extension subscriber at an exchange. This method relates to an RPU method using the Centrix function that does not answer and thus allows any nearby subscriber to receive a ringing call instead.

As is well known in the art, a national exchange provides a subscriber service function by grouping subscribers of a group into a unit, and controls a subscriber group provided with the centric function by an input outpu processor (IOP) of the exchange. By enabling the service of the Centrix feature, the addition or deletion of other Centrix features is possible.

However, in the prior art, although the central exchange provides the centric function, the centric function can be grouped and serviced, but within the bundled group, a group is created and generated using the centric function in the local exchange again. There was a drawback that a group could not be RPU serviced using input / output.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and any extension that is bound to the same RPU group when the subscriber in ring does not answer when any subscriber requests an extension to the extension at the exchange. It is an object of the present invention to provide a ring pick-up method using a Centrix function that allows a subscriber to dial an RPU code and make a response instead.

In order to achieve the above object, the present invention provides a guide call control unit for transmitting / receiving a subscriber and a relay line in the same group, a number translation unit for receiving a number translation request from a preset line control unit, and performing a number translation function; It has a phone number assigned to subscribers under the control of the guidance call control unit, and stores the information of each centric group and the extension subscribers within each centric group, thereby managing subscribers according to the grade and other special services. In an exchange system including a central data processing unit for executing a network and an input / output processor (IOP) for inputting a command from a tester and monitoring an operating state of the exchange, an arbitrary subscriber is connected to a relay line or an extension. Requesting a call to any subscriber; and receiving the caller's requested information Storing in a buffer of the data processing unit, hooking off an RPU code by an arbitrary extension subscriber to receive a call of a ringing subscriber, and a terminal of a subscriber hooking off to receive a call of a ringing subscriber; A determination step of determining whether the subscriber station in the ring is the same RPU group; and if the subscriber station in the same group is determined in the determination step, erasing data stored in the buffer of the central data processing unit corresponding to the subscriber in the ring; The present invention provides a ring pick-up method using a Centrix function, comprising: cutting a ring signal of a subscriber in progress and connecting to a terminal of a subscriber who has hooked off to receive a call of a subscriber in ring.

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings.

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

Referring to FIG. 1, the configuration of the present invention is controlled by a line controller 102 for connecting signals between stations and subscribers through a power station to another station, and a call path installed in the premises under the control of the line controller 102. Receives a call, receives a command from the input and output unit 118, and controls the line control unit 102 to transmit the call signal, the centric line control unit 104, and the preset call established through the line control unit 102 Subscriber line control unit 106 that controls outgoing / incoming connection to the originating / receiving subscriber of the local station controlled by the exchange 10, and outgoing / incoming connection to the originating / receiving subscriber of another station entered through the line control unit 102. The relay line control unit 108 that controls the control, and outgoing processing for subscribers and relay lines within the same group, and guidance for receiving and receiving calls from the subscriber line control unit 106 and the relay line control unit 108. A call control unit 110, a number translation unit 112 for receiving a number translation request and performing a number translation function, and a telephone number assigned to a subscriber under the control of the guide call control unit 110, and having a cent. Enter the instructions from the tester and the Centrix data processing unit 114 that stores the information for each Rx group and the information of the extension subscribers in each Centrix group, and performs subscriber management according to the grade and other special services. And an input / output processor (IOP) 116 for monitoring the operating state of the exchange 10.

Referring to FIG. 1, a block diagram of an exchange including an input / output unit suitable for ring pick-up using the Centrix function will be described in detail. The line controller 102 can detect the change of states of an analog subscriber, a relay line, and a digital line. Supervisory control and analysis reports the status changes of lines and relay calls to higher processors.

When the call of the subscriber is input, the line controller 102 transmits a message such as a setup message from the subscriber, information messages such as digit information and device number, a call connection request, a call termination request, and the like, to connect signals between stations. In this case, the subscriber is connected to the other station through a large country, and the call is terminated according to the hook on of the subscriber.

The centrix line control unit 104 receives the call path installed in the premises remotely from the local exchange 10 under the control of the line control unit 102, and receives a command or a call request from the guide 118 to control the line control unit 102. ), So that calls can be routed between Centrix groups, own stations, or other stations.

As a result, Centrix users are often referred to as "virtual private networks" in the sense that private networks exist.

The subscriber line control unit 106 connects the incoming call terminal and the incoming call line with digit information on the signal received from the originating subscriber of the local station controlled by the local exchange 10 through the line control unit 102, and then the incoming telephone. The intermittent call signal is sent to the calling subscriber.

When the call is sent from the Centrix group through the input / output unit 116 and the call is received by the subscriber in the local exchange 10, the centric line control unit 104, the subscriber line control unit 106, and the line control unit 102 are connected. It connects subscribers in their home country with those in the Centrix group.

The relay line control unit 108 connects the incoming callee terminal and the incoming call line with the digit information of the signal received from the originating subscriber of another station through the line control unit 102 and sends the intermittent call signal to the called telephone. A call ringing is sent, and a call that is directed to a called party in another country detects and occupies and allocates an empty relay line among the relay lines to the called party.

When the call is sent from the Centrix group through the guide 118 and the call is received by the subscriber of the other exchange, the C Line line 104 through the relay line control unit 108 through the line control unit 102 through the line control unit 102. Connect between the called party in other country and the calling party in Centrix group.

The guide call control unit 110 may use the inbloc and overlap schemes as a block for outgoing processing for subscribers and relay lines within the same group, and the incoming call processing may be received from a subscriber group. In the case of a call, the call is received and received by the centric line control unit 104, and when the call is received from a subscriber in the same local exchange 10, the call is received and received by the subscriber line control unit 106, When a call is received from a subscriber of another station, the call is received from the relay line control unit 108 and the call is received.

The number translation unit 112 has a telephone number assigned to the subscriber, and if there is a request for translation of the number from each of the centric line control unit 104, the subscriber line control unit 106, and the relay line control unit 108, By performing the translation function, information on the called subscriber or relay line required is provided in each block.

The number translation results include mounting position information for the called number or relay line information.

The Centrix data processing unit 114 is connected to the guide call control unit 110 to store the information of the Centrix group and the extension subscriber information within each Centrix group, and manages subscribers and other special services according to the grade. As a block for implementing the above, it is possible to receive the service having higher reliability and call history at the local exchange 10 than the ordinary private exchange.

The input / output unit 130 receives the operator's command, performs the received command, informs the operator of alarm information and call information, and periodically informs the operator of the operating state of the exchange, and at the request of the operator, switches of other exchanges. Is displayed to the subscriber so that the operator can easily see the information of the exchange.

Referring to FIG. 2, the ring pick-up using the Centrix function in the switch according to the present invention will be described. When registering the night service function, a directory number (DN) of the night service is obtained through a MMC command. Register.

Any subscriber makes a call request to any extension subscriber to the relay line or extension (step 202).

The information of the called-in subscriber is stored in the buffer of the central data processor 114 (step 204).

At this time, the called party is in a ring state (step 206).

Any extension subscriber hooks off to receive a call from a ringing subscriber (step 208).

When the line control unit 102 detects this and notifies the Centrix line control unit 104 of the ring state in order to receive a call of a subscriber who is ringing in the same group as the ring state, the line control unit 102 receives an extension dial tone.

At this time, the RPU code is dialed to perform the RPU (step 210).

As an example of the ring pick-up code, the RPU code is set through the input / output unit 116 with a hook-on signal for a predetermined time, "*", "#", a preset number, and a combination of the above examples.

In order to receive the call of the subscriber in the ring, it is determined whether the terminal of the subscriber who has hooked off and the subscriber terminal in the ring are the same RPU group (step 212).

If the distances are close but the groups are different, the RPU service function cannot be used, and thus the change is possible through the input / output unit 116 so that the ring pick-up function can be separately set between the other groups.

If it is determined in step 212 that the subscriber station is not in the same group, the busy tone is transmitted to the terminal of the subscriber who has been hooked off to receive the call of the subscriber who is ringing (step 214).

If it is determined in step 212 that the subscriber station is in the same group, the data stored in the storage RPU buffer is deleted in step 204 corresponding to the subscriber in the ring (step 216).

The ring signal of the ringing subscriber, that is, the called party, is disconnected (218).

In order to receive a call of a subscriber who is ringing a call requesting an extension subscriber, the terminal hooks off and connects the call of the calling party with the terminal of the subscriber who entered the RPU code (step 220).

When the call is connected, the call is connected between the calling party's terminal and the calling party's subscriber who hooked off to enter the ringing subscriber's call and entered the RPU code (step 222).

When canceling the ring pickup service function, the dial number of the night service is also canceled through the input / output unit 116.

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.

As described above, the present invention can provide a proper and efficient service to subscribers because when a group of people using the same department or office are grouped into the same RPU group, they can receive an ambassador when they do not have a person in their place. This process is easy because the ring doesn't go to the ringing colleague's seat to pick up the termination call.
