The present invention relates to a method for implementing a plurality of relay stations of a communication system, and more particularly, to a method of controlling a relay station group for each station group to control the role of the multiple relay stations.

In general, in a communication system, there is only one repeater or a group of repeaters, and thus, the call is switched to a CALL such as a HOLD RECALL and a TRANSFFER RECALL.

1 is a block diagram of a general communication system,

A central processing unit (10) for performing an exchange function and an overall control operation of the exchange system;

And a relay connection circuit 120 for interfacing the signal with the relay station 110 under the control of the CPU 10.

2 is a control flowchart for a conventional single transit implementation.

Referring to FIG. 1 and FIG. 2, the operation of performing a conventional single relay call transfer is described. In step 21, the central processing unit 10 transfers and recalls a Hold Recall. If there is a response within the set time, proceed to step 22 to perform a call. However, if there is no response within the set time, the central processing unit 10 checks whether there is a repeater or repeater group in step 23 and proceeds to step 25 if there is a repeater or repeater group. In step 25, if there is a subscriber in the dormant form among the relay station or the relay station group, the process returns to step 21 if there is no subscriber in the dormant state. In step 26, the central processing unit 10 transmits a ring signal to the relay station 110 through the relay connection circuit 120 and terminates the program. However, if there is no repeater or repeater group in step 23, the process proceeds to step 24 and it is not possible to pick up the call. If the recall time is over, the call is automatically disconnected and the program ends.

In a large-scale communication system when transferring a call using a single repeater as described above, when different floors are shared by one system among different departments or when multiple floors are shared by one system in a building, the call is called. If there is no professional operator (OPERATOR) because the call is gone to a place other than the relevant department or the corresponding floor, the call processing is difficult, and the externally called subscriber has an inconvenience of having to call again.

Accordingly, an object of the present invention is to solve the above problem, when a call is switched to a relay station by HOLD RECALL, TRANSFFER RECALL, etc. in a communication system, the call is transferred to another subscriber and call processing is stopped. It is to provide a method to prevent.

Another object of the present invention is to provide a method for preventing confusion of a call between barges or floors by designating a relay station or a relay station group for each extension group in a communication system.

In order to achieve the above object, the present invention provides a process of searching for whether a relay station or a relay group is assigned to a group to which a group belongs to when there is no response within a set time for holding recall and transmission recall; If a relay station or a relay group is designated in the step of transmitting a ring signal as a relay when there is a subscriber in the idle state among the designated groups, and the relay or relay group is not assigned to the group to which the group belongs. Searching whether there is a relay station or a relay group of the time system, searching for any idle members in the group when the system relay or relay group is present, and relaying when there is a subscriber in the idle state As soon as there is no system repeater or group of repeaters, you can pick up the call. It is characterized by consisting of a process of automatically cutting the call when the high recall time elapses.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The hardware block diagram according to the present invention is the same as that of FIG. 1, and the reference numerals are the same. 3 is a control flow diagram for implementing a plurality of relays according to the present invention,

Searching for a response within a set time for held recall and outgoing calls;

Forming a call when there is a response within the set time;

If there is no response within the set time, searching for whether a relay station or a relay group is assigned to the group to which the group belongs;

Transmitting a ring signal as a relay when there is a dormant subscriber in the designated group when the relay group or the relay group is assigned to the group to which the group belongs;

Searching whether there is a system repeater or repeater group when the repeater or repeater group is not assigned to the group to which the group belongs;

Searching for a dormant subscriber in the group when the system repeater or repeater group is present;

Transmitting a recall ring as a relay when the telephone is in the idle state;

If there is no system repeater or repeater group, the call can be picked up and the call is automatically cut when the recall time elapses.

One preferred embodiment of the present invention will be described in detail with reference to FIGS. 1 and 3 above.

First, in step 31, the CPU 10 checks whether there is a response within the set time for the Transfer Recall and the Hold Recall, and if there is a response within the set time, proceeds to step 32 to perform the call. do. However, if there is no response within the set time, the central processing unit 10 checks whether the relay group or the relay group is assigned to the group to which the group belongs. Proceed. In step 34, the central processing unit 10 checks whether there is a dormant subscriber in the relay station or a relay group, and waits until there is a dormant subscriber, and if there is a dormant subscriber, step 37 Proceed to In step 37, the central processing unit 10 transmits a ring signal to the relay station 110 through the relay play circuit 120 and terminates the program. However, in step 303, if the relay group or the relay group is not assigned to the group to which the group belongs, the process proceeds to step 35, and the central processing unit 10 checks whether the relay station or the relay group of the system exists, If there is a repeater group, proceed to step 36. In step 36, the central processing unit 10 checks whether there is a dormant subscriber in the system repeater or a group of repeaters, and proceeds to step 37 if there is a dormant subscriber. In step 37, the central processing unit 10 transmits a ring signal to the relay station 110 through the relay connection circuit 120 and terminates the program. However, if there is no repeater or repeater group in the system in step 35, the process can be picked up in step 38. If the recall time is over, the call is automatically disconnected and the program ends.

As described above, the present invention has the advantage of preventing the confusion of calls between departments or different floors by designating a relay or relay group for each extension group.
