Abstract

PURPOSE:To inform a transmitter whose call is rejected by having a means to store the subscriber number of an incoming call generated in a telephone set during an incoming rejection setting and a means to retrieve the subscriber number of the incoming call generated during the incoming rejection setting from the telephone set. CONSTITUTION:When a subscriber terminal 41 registers the incoming rejection by a dial operation and the like, a central controller 2 recognizes the subscriber terminal 41 as an incoming rejection extension and executes an incoming rejection control. When a subscriber terminal 42 calls the subscriber terminal 41 during the incoming rejection, a busy tone is returned to the subscriber terminal 42, the telephone number of the subscriber terminal 42 which is a caller is temporarily displayed on the display part of the subscriber terminal (telephone set) 41, the subscriber terminal 41 can immediately recognize an incoming and simultaneously the central processor 2 works to write the telephone number of the subscriber terminal 42 which is the incoming into a caller telephone number storage memory 5 corresponding with the subscriber terminal 41.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an incoming call rejection system in an electronic exchange that employs a storage program system.

(Prior Art) Conventionally, electronic exchanges have been designed to temporarily not accept all incoming calls, or to only accept incoming calls from other than a specific subscriber, in case the subscriber is too busy to answer the phone. We provide our subscribers with a call rejection service that allows them to block incoming calls.

[Problem to be solved by the invention]

In conventional electronic exchanges, the call rejection service does not accept incoming calls from all unspecified subscribers, or if the caller additionally dials a special number predetermined by the call rejection extension, or if the call rejection extension This service allows incoming calls to be accepted only if the call is made from a pre-specified telephone (subscriber number), and the information on incoming calls that have been rejected is heartbreaking. Therefore, after the subscriber who rejected the call becomes available for calls, it is not possible to contact the caller whose call was rejected again. It has the disadvantage that it may cause inconvenience in cases such as.

An object of the present invention is to provide an incoming call rejection system that solves the above problems.

[Means to solve the problem]

In order to achieve the above object, an electronic exchange that adopts the storage program method according to the present invention has a means for setting incoming call rejection from a telephone set, and a means for storing the subscriber number of an incoming call that occurs on a telephone set for which incoming call rejection is set. means for displaying the subscriber number of the incoming call on the display section of the telephone set in which the incoming call is being rejected; and means for searching the telephone set for the subscriber number of the incoming call that occurred during the incoming call rejection setting.

〔Example〕

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

FIG. 1 is a diagram showing an embodiment of the call rejection service of the present invention, which stores the telephone number of the caller when the call is rejected.

The switch network 1 accommodates subscriber terminals 41 to 411 and
It is controlled by a central control device 2. The central controller 2 has memories such as a calling party's telephone number storage memory 3, and one calling party's telephone number storing memory 3 has a memory area reserved for each subscribed end.

Subscriber terminal 4. When the subscriber registers call rejection by dialing or the like, the central control unit 2 recognizes the subscriber terminal 4□ as a call rejection extension and performs call rejection control.

When the subscriber terminal 42 makes a call to the subscriber terminal 41 that is rejecting calls, a busy tone is returned to the subscriber terminal 4□, and the subscriber terminal (telephone) 4. The telephone number of subscriber terminal 4□, which is the caller, is temporarily displayed on the display section of subscriber terminal 4. In addition, the system centralizes the work of writing the telephone number of the subscriber terminal 4□, which is the incoming call, into the calling party telephone number storage memory 5 corresponding to the subscriber terminal 41. By dialing a special number by the control device 2 and by the subscriber terminal 41, the telephone number of the incoming call that occurred during the incoming call rejection stored in the corresponding memory is displayed on the display of the telephone. Alternatively, part or all of the contents of the calling party telephone number storage memory 5 can be cleared.

〔Effect of the invention〕

As explained above, the present invention provides a means for setting incoming call rejection from a telephone set, a means for storing the subscriber number of an incoming call that occurs on a telephone set for incoming call rejection, and a means for storing a subscriber number of an incoming call that occurs on a telephone set for incoming call rejection, in an electronic exchange that adopts the storage program method. By having a means for displaying the subscriber number of an incoming call on the display section of the telephone, and a means for searching the subscriber number of an incoming call that occurred while the incoming call rejection was set, the incoming call that occurred while the incoming call was rejected It is possible to know the subscriber number of the call, and it is also possible to contact the subscriber number of the incoming call if necessary, so that the call rejection service can be used without causing any inconvenience for important matters. There is an effect that can be done.
