Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a subscriber selection service control system for electronic switching functions, and in particular, in order to achieve effective and flexible operation for incoming calls, This invention relates to subscriber selection service control that can change the pilot terminal that starts subscriber selection service control depending on the time of day.

[Conventional technology]

What is the subscriber selection service function? When a call comes to a representative number, multiple terminals A, B, C, etc. are prepared and connected to terminal A first, and if terminal A is in use, This is a service function of an exchange, such as connecting to terminal B when terminal B is in use, and connecting to terminal C when terminal B is also in use, and is also called representative selection, but hereinafter referred to as hunting.

There are two types of hunting services: a method in which hunting is always performed from a fixed terminal, and a method in which multiple pilot numbers are provided and hunting is performed from the terminal corresponding to each pilot number. The pilot referred to here is the subscriber telephone that can be called first among the plural subscriber telephones (the subscriber telephone that is called first).

[Problem that the invention seeks to solve]

In all of the above hunting service methods, the first terminal that receives a call is always fixed, so in order to bypass the next terminal, it is necessary that the terminal is in use. The disadvantage of this system was that it lacked flexibility in terms of usage conditions for telephone terminals and the effect of distributing incoming traffic.

[Means for solving problems]

A means for solving the problem is that in an exchange system having a subscriber selection service function and a time readable clock function, a memory having information on one or more first-come-first-served terminals in the subscriber selection service group is provided. , time reading unit, call destination determination unit,
and a table for specifying the first-arrival terminal according to the time, and for a call that arrives to the subscriber selection service group, the destination determination section specifies the first-arrival terminal according to the time instructed by the time reading section and the table. This is achieved by a subscriber selection service control method that determines available terminals and controls incoming calls.

[Effect]

According to the present invention, for a call that arrives to a subscriber selection service group, the first available terminal is selected according to the time when the call occurred and a predefined table, and the subscriber selection service is performed from that terminal. It is possible to respond to changes in telephone terminal usage conditions such as daytime, nighttime, and holidays, and to distribute incoming traffic, resulting in the effect that a subscriber selection service with high operational flexibility can be realized.

〔Example〕

FIG. 1 is a schematic diagram illustrating an embodiment of a subscriber selection service control method according to the present invention.

FIG. 2 is a diagram showing an example of the configuration of a hunting group according to the present invention.

FIG. 3 is a diagram showing an example of a memory configuration regarding hunting time designation according to the present invention.

In the figure, NW is the network, CC is the central control unit, SWC is the switching control unit, HSW is the destination determination unit,
MHC is the hunting control unit, TIMER is the clock,
A to F are subscriber telephones forming a hunting group, and MM is a main storage device. The same symbols represent the same objects throughout all the figures below.

The hunting group is configured as shown in Figure 2, with subscriber phone A as pilot 1, subscriber phone C as pilot 2, and subscriber phone E as pilot 3.
are defined respectively.

Also, as shown in Figure 3, the time is set to 8:00 AM.
-5:00PM, designate Pilot 1,
It is defined that pilot 2 is specified between 5:00 PM and 9:00 PM, and pilot 3 is specified between 9:00 PM and 8:00 AM, and these definitions are stored as a table in the main storage device MM. I'll leave it there.

With this definition, when a call arrives at the hunting group at 11:00 AM, the call destination determination unit HSW operates, reads the time of call arrival from the clock TIMER, and then reads the above call from the main memory MM. The table is read and the first pilot to arrive is selected from the table and the current time.

As a result, the hunting control unit MHC is activated and, as shown in FIG. 2, first selects subscriber telephone A, and if subscriber telephone A is in use, selects subscriber telephone B. If subscriber telephone B is also in use, subscriber telephones C, D, etc. are selected as in the conventional hunting operation.

Also, when a call arrives at 11:00 PM, the destination determination unit HSW operates to read the arrival time from the clock TIMER, further reads the table from the main memory MM, and determines which pilot 3 should arrive first based on the table and the current time. Select.

As a result, the hunting control unit MHC is activated,
The incoming call processing is started from subscriber telephone set E, and processing is performed as if a group was formed between subscriber telephone set E and subscriber telephone set F.

As mentioned earlier, the time specification is stored in advance in the main memory MM by a command, but by setting the time specification to two types, odd-numbered times and even-numbered times, it is also possible to equalize the opportunities for subscriber telephones to respond. It is possible.

Further, flexibility can be provided by preparing several types of the above-mentioned tables and selecting and using an arbitrary table at any time.

Furthermore, the above explanation is based on the SR method (Sequence
Rotation) as an example, but as is clear from the above explanation, it is also applicable to the SB method (Switch Back).

〔Effect of the invention〕

As explained in detail above, according to the present invention, it is possible to respond to changes in telephone terminal usage conditions such as daytime, nighttime, and holidays, and it is also possible to distribute incoming traffic, allowing for highly flexible subscriber selection in terms of operation. This has the great effect of enabling services to be realized.

Claims (1)

[Claims] 1. In an exchange system that has a subscriber selection service function and a clock function that can read the time,
A memory having information on one or more first-arriving terminals in the subscriber selection service group, a time reading section, a call destination determination section, and a table for specifying the first-arriving terminals by time are provided, and the subscriber selection service group The subscriber selection service control is characterized in that, for a call that arrives at the terminal, the destination determination section determines the terminal that can arrive first according to the time indicated by the time reading section and the table, and controls the arrival of the call. method.
