Abstract

PROBLEM TO BE SOLVED: To enhance the utilizing efficiency of a line by using a past external line call reception history, when making an external dialing. SOLUTION: A recording device 5 records an incoming call history, by identification of the arrival of the incoming call from an external line 1 to an incoming call monitor circuit 4. An arithmetic device 6 calculates frequency of the external line incoming calls based on the incoming call history. A channel switch 3 selects an external line used at external line dialing. A controller 7 selects an external line used at external dialing based on the frequency of incoming calls. The controller 7 selects external lines with low frequency of incoming calls with priority. With this configuration, the external line with low frequency of the arrival of the incoming calls is used with priority and an external line with high frequency of incoming calls is made idle, to decrease the probability that is busy at the arrival of incoming calls and the line utilizing efficiency is enhanced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching device and a switching control method in a premises accommodating a plurality of external lines.

[0002]

2. Description of the Related Art Conventionally, an exchange device and an exchange control method are as follows.
For example, the present invention is applied as an on-premises switching facility that accommodates a plurality of external lines. In such an exchange device and exchange control method,
Outgoing lines in the outgoing / incoming / outgoing line are selected by the user or are sequentially captured according to the setting of the main device, and the history of the incoming call frequency and the like in each external line is not particularly considered.

[0003] For example, in Japanese Patent Application Laid-Open No. 6-141360, "outgoing line selection method", priorities of line use are set in a storage circuit in advance, and a vacant line having the highest priority is selected to communicate with a calling terminal. It is said to be connected to a line.

[0004]

However, in the prior art, since an outside line is captured according to the user's judgment at the time of outgoing line transmission or the order according to the setting of the main unit, even if there is another vacant outside line with a low frequency of incoming calls. Regardless, an outside line with a high frequency of incoming calls may be captured. If there is an incoming call at this time, the incoming call cannot be received until the previously transmitted call ends. In an outside line with a high frequency of incoming calls, the probability of being on a call is increased by the outgoing call, which causes a reduction in line use efficiency.

The present invention has been made in view of the above-mentioned problems, and has as its object to provide a switching apparatus and a switching control method in which the use efficiency of a line is improved by using a past incoming line history at the time of outgoing calls. And

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a switching apparatus and a switching control method according to the first and fourth aspects of the present invention. Is calculated. Select an outside line to be used for outgoing calls based on the calculated incoming frequency.

[0007] With this configuration, it is possible to increase the use efficiency of the line by leaving a line with a high frequency of incoming calls.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention relating to the switching device according to the first aspect is characterized in that: a recording means for recording a history of incoming calls from outside lines;
Calculating means for calculating an incoming frequency of an outside line based on the incoming call history;
A communication path switch for connecting an outside line used for calling an outside line, and a control unit for selecting a connection based on the frequency of incoming calls are employed.

[0009] With this configuration, it is possible to improve the line use efficiency by reducing the probability that the user is talking during a call.

According to the second aspect of the present invention, the control means includes:
A configuration is adopted in which selection is performed with priority given to an outside line having a low incoming call frequency.
With this configuration, priority is given to using the outside line with low incoming frequency for outgoing calls, and leaving the outside line with high incoming frequency as priority.
The usage efficiency can be improved.

[0011] According to the third aspect of the present invention, the exchange device comprises:
A configuration is further provided which has an incoming call monitoring means for checking whether there is an incoming call from an outside line. With this configuration, it is possible to more reliably obtain the incoming call history and the like.

According to a fourth aspect of the present invention, there is provided an exchange control method, comprising: a recording step of recording an incoming call history from an outside line; a calculating step of calculating an incoming call frequency of the outside line based on the incoming call history; A configuration having a communication channel selection step to select and a control step to select a connection based on the frequency of incoming calls is adopted.

[0013] With this configuration, it is possible to increase the line use efficiency by reducing the probability that the user is talking during a call.

[0014] In the invention described in claim 5, the control step includes:
A configuration is adopted in which selection is performed with priority given to an outside line having a low incoming call frequency.
With this configuration, priority is given to using the outside line with low incoming frequency for outgoing calls, and leaving the outside line with high incoming frequency as priority.
The use efficiency of the line can be improved.

According to the invention described in claim 6, the switching control method employs a configuration further including an incoming call monitoring step of checking whether there is an incoming call from an outside line. With this configuration, it is possible to more reliably obtain the incoming call history and the like.

Next, an exchange apparatus and an exchange control method according to an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing a switching device, a switching control method, and its periphery according to an embodiment of the present invention. The outside line 1 and the inside line 2 are accommodated in the exchange device 8 of FIG.
The switching device 8 includes a communication path switch 3, an incoming call monitoring circuit 4, a recording device 5, a computing device 6, and a control device 7.
The outside line 1 is connected to the incoming call monitoring circuit 4 of the above-mentioned component, and the outside line 2 is connected to the communication path switch 3, and each is accommodated.

In the switching device 8 configured as described above, the incoming call to the outside line 1 is stored in the recording device 5 by the incoming call monitoring circuit 4 as an incoming history for each outside line. For the transmission from the extension 2 to the outside line, the arithmetic unit 5 calculates the incoming call history,
The control unit 7 automatically selects the communication path switch 3 for capturing the outside line L having a low incoming call history, and the connection is controlled by the communication path switch 3. By this control, it is possible to avoid allocating an outside line with a high frequency of incoming calls to outgoing calls and to reduce the state during a call, thereby improving the efficiency of using outside lines.

FIG. 2 is a flowchart showing an operation example of the switching device. In this flowchart, when there is an outgoing / incoming call in step S1, it is checked whether or not the incoming call is from an outside line (S2). If the result of this check is YES, the incoming call history is stored for each line in use (S3).

If there is no incoming call from outside line (S2 / N),
It is checked whether the call is from an extension to an outside line (S4). If the result of this check is yes, the incoming call history is calculated (S5). Based on the calculation of the incoming call history, an outside line L having a low incoming call frequency is captured (S6). When there is a call from the extension to the outside line, the connection to the captured outside line L is controlled as the outside line used for the call (S7).

[0020]

As is clear from the above description, claim 1
According to the switching device and the switching control method according to the inventions described in (4) and (4), the incoming call history from the outside line is recorded and the incoming line frequency of the outside line is calculated. Based on this frequency of incoming calls, an external line to be used is selected so as to keep a busy line free when an external line is transmitted. Therefore, an outside line with many incoming calls is in use by outgoing calls, and the probability of an incoming call being unsuccessful is reduced, and line use efficiency can be improved.
