Abstract

PURPOSE:To inhibit any incoming call until the wake-up call time by one registration setting operation by designing said system that the incoming limit service is set automatically when the wake-up call sevice is set. CONSTITUTION:When a wake-up call service is registered, a subscriber (STA) 11, for example, dials a prescribed number. Then a central controller (CC) 5 applies wake-up call setting processing and then applies incoming limit processing. When an incoming call comes to the STA 11, the CC 5 reads the incoming limit information in a memory area 61, the call is not connected to the STA 11 being a called party and a busy tone is sent to a caller.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Field of Industrial Application] The present invention relates to an incoming call restriction control system, and more particularly to an incoming call restriction control system for a subscriber in a private branch exchange.

[Conventional technology]

Conventionally, in this type of private branch exchange, such as a hotel exchange, when restricting incoming calls to a certain subscriber, the incoming call restriction registration settings are made separately from the registration settings for other services, such as a wake-up call service. -) If a subscriber registers for a wake-up call service, listens to the service settings, goes on-hook, then goes off-hook again and performs call restriction registration, the subscriber's
\ was designed to prevent incoming calls other than wake-up calls.

[Problem to be solved by the invention] In the conventional incoming call restriction control system, when it is desired to restrict incoming calls before the subscriber's wake-up call is called, the subscriber or the operator of the hotel switchboard must Since you have to register for the incoming call restriction service in addition to registering for the wake-up call service, the service is not easy to use.

[Means for Solving Problem 1] The incoming call restriction control system of the present invention has a central control unit and a memory area for storing incoming call restriction information for each subscriber. When any operator of the private branch exchange performs a service registration operation other than restricting incoming calls to the subscriber, the central control unit performs control processing to store incoming call restriction information in the memory area corresponding to the subscriber. There is.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a flowchart showing an example of the control processing of the central control unit in FIG. 1 for country 11,172 of a hotel switchboard showing one embodiment of the incoming call restriction control method of the present invention, and the second country is a flowchart showing an example of the control processing of the central control unit in FIG.

In Figure 1, a hotel exchange has multiple subscribers (hereinafter 5
TA)11. A communication path switch (hereinafter referred to as 5W) 3 that connects ~1n and the office line relay board (hereinafter referred to as ATT>2 and transmission register 1 to rank (hereinafter referred to as 0RT) 4), and a central control unit that controls all sequence control processing within the hotel exchange. (Below (:1
．． C) 5, and a main storage device (hereinafter M M > 6) that stores programs executed by the CC 5 and various data, and M M 6 has a memory area 61. to 61. to store incoming call restriction information corresponding to 5TA11. to 1n. It has 6n.

Next, the operation of this embodiment will be explained.

First, when registering for the wake-up call service, for example, 5TAII makes a call, and via SW3, OR, T4
After hearing the dial tone from 0RT4, the CC5 dials the predetermined number, and upon receiving this number information from 0RT4, it analyzes the number as shown in Figure 2 and determines that it is a request to set up a wake-up call by 8TA11. Performs the wake-up call setting process. Next, CC5 is 5TAII
Performs incoming call restriction setting processing for. That is, CC5 is M
After storing, for example, the logical value Pa1°' in the memory area 61 corresponding to 8""A1" of M6, the service setting sound transmission process to 5TAII is performed.

After that, when a call arrives at 5TA II from, for example, 5TAI n, ATT2, or a central office line or private line (not shown), the C
The C5 performs generally known incoming call connection processing, and reads the incoming call restriction information from the memory area 61 and connects the called party to the called party 5TA.
A busy tone is sent to the caller without connecting to II.

The above is a similar operation when setting the wake-up call service from 5TAFF, or from other subscribers, or from an ATT2 handler or hotel front desk employee based on a subscriber's request.61 , Effects of the Invention'1 As explained above, the present invention automatically sets a wake-up call service when a wake-up call service is not set for a certain subscriber. You can sleep soundly as you won't receive any calls until the call setting time, and you only have to perform the registration settings once.
Subscribers and handlers'! 4a) There are effective prefectures that can reduce the burden.

Claims (1)

[Claims] In a private branch exchange equipped with a central control unit and a memory area for storing incoming call restriction information for each subscriber, either the subscriber or the operator of the private branch exchange performs service registration operations other than restricting incoming calls to the subscriber. An incoming call restriction control method, wherein when the central control unit performs control processing to store incoming call restriction information in the memory area corresponding to the subscriber.
