JPH02135961A - Busy encounter call informing system in exchange system - Google Patents

Abstract

PURPOSE:To obtain incoming information during performing communication after the completion of the communication without disturbing the communication in performing by storing the incoming information in busy, and informing the stored incoming information of a call arrived during performing the communication after completing the communication. CONSTITUTION:In the case of receiving an incoming call when a terminal 1 is in busy, a central control part 5 stores the incoming information in a storage part 6, and monitors whether or not the terminal 1 goes to a null state via a subscriber line control part 3. When it is detected that the null state of the terminal 1 is generated and a response to the terminal 1 by applying the incoming call is performed, the incoming information in the storage part 6 is informed in voice from a voice informing part 7 via an exchange switching part 4, and informs the fact that the incoming call arrives during performing the communication. In such a manner, it is possible to obtain the incoming information during performing the communication after the completion of the communication without disturbing the communication in performing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a system for notifying information about a busy encounter call in a switching system.

[Conventional technology]

Conventionally, in a switching system, when a terminal receives an incoming call while the terminal is in the middle of communication, the method of notifying the terminal is to make the terminal that is currently communicating play an incoming call notification tone at the time of the incoming call, and to alert the unused terminal. There was a method for answering incoming calls through operation.

[Problem to be solved by the invention]

The incoming call notification method in the conventional switching system described above allows the incoming call notification sound to be heard during communication, so when the user has no intention of answering the incoming call, the incoming call notification sound may cause discomfort to unused users. be.

Furthermore, if the caller disconnects the call before answering, there is a drawback that not only can the caller not know where the call came from, but also if there are multiple calls. Furthermore, there is a drawback for the caller as well, in that if the called terminal does not respond to an incoming call during communication, the caller is forced to wait in a ringing state and assumes that the caller is not present.

[Means to solve the problem]

The busy encounter call notification method of the switching system of the present invention has a function of notifying the telephone number of the calling terminal from the calling station to the receiving station when setting up a call, and when the connected terminal cannot process the incoming call, the corresponding call is called an incomplete call. In a switching system, means for storing incoming call information such as a calling terminal telephone number and time of an incoming call to a busy terminal; and means for notifying the busy terminal of the incoming call information during the busy time stored in the means.

〔Example〕

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

Referring to FIG. 1 showing an embodiment of the present invention, a switching network 2 that accommodates a terminal 1 includes a subscriber line control unit 3 that monitors and controls the terminal 1, an exchange switch unit 4 that performs switching operations, A central control unit 5 that controls the entire switching network and performs call control, a storage unit 6 that stores various types of incoming call information (calling terminal telephone number and time) of busy encounter calls, and notifies the terminal 1 of incoming call information by voice. It is composed of a voice notification section 7.

When there is an incoming call while the terminal 1 is busy, the central control section 5 stores the incoming call information in the storage section 6 and monitors through the subscriber line control section 3 until the terminal 1 becomes empty. When it is detected that terminal 1 is in an empty state, an incoming call is placed on terminal 1 and the call is answered.
The voice notification section 7 notifies the incoming call information in the storage section 6 by voice via the exchange switch section 4 to notify that there is an incoming call during communication. Here, the notification opportunity may be not when the terminal 1 becomes empty, but when a notification request is received from the terminal 1. Further, the notification method may be a text signal or the like in addition to voice.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to prevent communication during a communication by storing incoming call information during a busy time and notifying the incoming call information of a call that was received during the communication after the communication is completed. After the end of the communication, the incoming call information during the communication can be obtained.

Claims (1)

[Claims] In a switching system that has a function to notify the telephone number of the calling terminal from the calling station to the terminating station when setting up a call, and treats the call as an incomplete call when the connected terminal cannot process the incoming call, an incoming call to a busy terminal is means for storing incoming call information including a telephone number and time of a calling terminal; A busy encounter call notification method for a switching system, comprising means for notifying a busy terminal.
