Description

[Detailed description of the invention] The present invention relates to a representative selection method for an automatic exchange.

In the conventional representative selection method, the representative selection group in the representative selection memory is determined based on the receiving side accommodation location information and the representative selection group information, and is fixedly stored in the representative selection memory corresponding to each representative selection group. A method was adopted in which incoming calls were distributed only according to the order in which the accommodation location information of one type of extension was collected. Therefore,
Incoming calls are not evenly distributed among the extensions that belong to each extension representative group, and the same representative selection group is used even during times when there are a large number of incoming calls, and conversely during times when there are few incoming calls, which reduces the efficiency of equipment and personnel. The drawback was that it could not be used.

An object of the present invention is to store representative selection group information selected in correspondence with receiving side accommodation location information and call arrival time information, and accommodation location information of an extension previously selected in correspondence with this representative selection group, and to control the storage information. Therefore, it is an object of the present invention to provide a representative selection method that solves the above-mentioned drawbacks.

The features of the present invention that achieve the above object include a circuit for identifying the receiving side accommodation location information, a representative selection memory reading circuit, a clock circuit, and storing representative selection group information corresponding to the receiving side accommodation location information and the time of call arrival. a memory for storing accommodation position information of an extension that received a previous call corresponding to a representative selection group; and a memory for storing accommodation position information of an extension belonging to each representative selection group divided for each representative selection group. A representative selection memory controlled by representative selection group information, accommodating position information of the extension that received the last call corresponding to the representative selection group, and accommodating position information stored separately for each representative selection group of extensions belonging to each representative selection group. A matching circuit is provided for comparing the accommodation position information stored separately for each representative selection group of extensions belonging to each representative selection group in the representative selection memory and the extension of the extension that received the last call corresponding to the representative selection group. The purpose is to distribute incoming calls by comparing the accommodation location information with the checking circuit.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an embodiment of the invention. In FIG. 1, when a call arrives, the receiving side accommodation location identification circuit 1 transfers the extension accommodation location information stored in the internal extension accommodation location information storage register 21 to the extension accommodation location information storage register 22 in the representative selection memory reading circuit 3. Output. When the extension accommodation position information is input to the extension accommodation position information storage register 22, the representative selection memory reading circuit 3 reads time information from the clock circuit 4 to the time information storage register 51. Next, this time information is stored in the time information storage register 52 of the representative selection group information memory 6, and the extension accommodation position information previously input from the receiving side accommodation position identification circuit 1 is stored in the representative selection group information memory 6. Each is output to the register 23. The representative selection group information memory 6 uses the time information input to the time information storage register 52 and the extension accommodation location information input to the extension accommodation location information storage register 23 to store extension accommodation location information and time via the memory address control circuit 71. In response to the information, the memory 8 that stores representative selection group information of the representative selection group to which this extension belongs at that time is referred to, and the representative selection group information of the representative selection group to which this extension belongs to that time is representative selection. The representative selection group information that is output to the group information storage register 91 and further input to the representative selection group information storage register 91 is output to the representative selection group information storage register 92 of the representative selection memory reading circuit 3. The representative selection memory readout circuit 3 stores the representative selection group information input to the representative selection group information storage register 92 into a temporary storage memory 10.
The data is output to the representative selection group information storage register 93 of , and the representative selection group information register 94 of the representative selection memory 11 . In the temporary storage memory 10, based on the representative selection group information input to the representative selection group information storage register 93, reference is made to the memory 12 that stores the accommodation position information of the extension that arrived last time corresponding to the representative selection group through the memory address control circuit 72. Then, the accommodating position information of the extension that received the previous call in this representative selection group is output to the extension accommodating position information storage register 24. Further, the temporary storage memory 10 outputs the extension accommodation position information outputted to the extension accommodation position information storage register 24 to the extension accommodation position information storage register 25 of the matching circuit 13.

On the other hand, in the representative selection memory 11, the extension accommodation position information belonging to each representative selection group is divided for each representative selection group through the memory address control circuit 73 based on the representative selection group information input to the representative selection group information storage register 94. Memory 141 for storing
14n is referred to, one of the accommodation position information of the extensions belonging to this representative selection group is sequentially read out and outputted to the extension accommodation position information storage register 26. Furthermore, the representative selection memory 11 outputs the extension accommodation position information outputted to the register 26 to the extension accommodation position information storage register 27 of the matching circuit 13. Next, the verification circuit 13
Then, the accommodation position information of the extension that received the previous call inputted into the extension accommodation location information storage register 25 and the accommodation location information of the extension read from the representative selection memory 11 inputted into the extension accommodation location information storage register 27 are internally verified. Verification is performed by circuit 15. As a result of the comparison, if they do not match, the representative selection group information stored in the representative selection group information storage register 92 of the representative selection memory reading circuit 3 is output to the representative selection group information storage register 94 of the representative selection memory 11, and each Memories 141-1 that store storage position information of extensions belonging to representative selection groups divided for each representative selection group.
Outputs the storage position information of the next stored extension that is read out first among the extensions belonging to this extension representative selection group of 4n to the extension storage position information storage register 26, and further outputs it to the extension storage position information storage register 27 of the verification circuit 13. Output to. The verification circuit 13 again compares the accommodation location information of the extension that received the previous call stored in the extension accommodation location information storage register 25 and the extension newly read out from the representative selection memory 11 and stored in the extension accommodation location information storage register 27. The storage position information is verified by an internal verification circuit 15. On the other hand, if the comparison results in a match, new extension accommodation location information is read out from the representative selection memory 11 in the same way as when there is no match, and this extension accommodation location information is used as the accommodation location information for the extension that will receive the call this time. This representative selection of the memory 12 stores the accommodation position information of the extension that arrived last time corresponding to the representative selection group through the memory address control circuit 72 according to the representative selection group information stored in the representative selection group information storage register 93 of the storage memory 10. The accommodating position information of the extension that will receive the current call is stored in the position corresponding to the group.

As shown in the embodiments of the present invention, by selecting a representative selection group suitable for the number of incoming calls at the call arrival time, equipment etc. can be used effectively, and furthermore, incoming calls can be transferred to extensions belonging to the same representative selection group. can be distributed evenly.

As explained above, the present invention stores representative selection group information to be selected corresponding to receiving side accommodation location information and call arrival time information, and accommodation location information of an extension selected last time corresponding to this representative selection group, and stores this stored information. By controlling the number of representative selection groups suitable for the number of incoming calls at the time of arrival, equipment can be used effectively, and calls can be evenly distributed to extensions belonging to the same representative selection group. There is a possible effect.
