Abstract

PURPOSE:To save labor expenses in an exchange, and to improve the quality of a service offered to a subscriber, by calling a callee subscriber automatically from an exchange side after completing a call, and informing the number of a caller subscriber, when a request to inform the number of the caller subscriber from the callee subscriber is issued in calling. CONSTITUTION:when the callee subscriber desires to know the number of the caller subscriber because the caller subscriber is a malicious subscriber who places a threatening call, the callee subscriber performs hooking. A call trunk detects thc hooking, and transfers it to a central processor CP. The CP memorizes instruction informing a malicious call in the corresponding trunk number area of a detail charging information memory area in a main memory MM. At a time when thc call is terminated, it is confirmed whether the instruction informing the malicious call is memorized in a memory corresponding to the trunk number in the detail charging information memory area, and when it is memorized, the trunk number, the number of the caller subscriber, and that of the callee subscriber are picked up, and are transferred to a malicious call searching information memory area, and the callee subscriber is called automatically based on the instruction of the malicious call searching information memory, and the number of the caller is informed in voice.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a system for notifying a called subscriber of the number of a calling subscriber who has made a telephone call in an exchange, that is, a system for notifying a called subscriber of the number of a calling subscriber who has made a telephone call, that is, a system for notifying a called subscriber of the number of a calling subscriber who has made a telephone call. This relates to the method of notifying persons.

[Conventional technology]

Conventionally, the method by which a called subscriber who receives a malicious call such as a threatening call can find out the number of the calling subscriber is as follows:
When the switching equipment receives hooking 2 from the called subscriber during a call, the switching equipment prints out necessary information such as the calling subscriber number, called subscriber number, call end time, etc.

Thereafter, there is a method in which a maintenance person at the switching center or the like notifies the called subscriber of this information. Related known examples include:
Japanese Patent Publication No. 52-18109 and Japanese Patent Publication No. 54-3380
There is No. 3.

[Problem that the invention seeks to solve]

In the above-mentioned prior art, it takes time from when the called subscriber requests to obtain information regarding the malicious call, that is, the telephone number of the calling subscriber, until the called subscriber actually obtains the information. moreover,
The above-mentioned calling subscriber's telephone number requires a lot of manpower for the exchange staff to search for the corresponding data from the printout data, which in turn increases personnel costs. Also, until the called subscriber requests and obtains the telephone number of the calling subscriber,
As mentioned above, the amount of time spent at the station is not constant because it is dependent on manpower, and it cannot be said that sufficient service is provided to telephone subscribers.

An object of the present invention is to solve these problems of the prior art. In other words, by eliminating the need to manually search for malicious call data at exchanges and automatically sending data to the called subscriber without taking much time, this will reduce the labor costs of exchanges. It is an object of the present invention to reduce costs and improve the quality of services provided to subscribers.

[Means for solving problems]

In order to achieve the above objects, the present invention provides: - During a call between a calling subscriber and a called subscriber, a calling subscriber number notification request signal is sent by instruction information from the called subscriber, such as hooking; When the call is communicated to the exchange, the exchange automatically calls the called party after the call ends, and has a means for notifying the calling party number using an automatic voice notification means.

C action] When the switching center receives a calling subscriber number request signal (for example, 9 King, etc.) from the called subscriber during a call, the control equipment of the switching The presence of a calling subscriber request signal is identified from the caller. In other words, it is known that there is a malicious call notification request. In the exchange, the calling subscriber number and called subscriber number of the call are transferred to a separate malicious call search information memory area from among various information already provided for switching connection operation and detailed billing allocation. I'll keep it. After the call ends,
(The called party number is retrieved from the above-mentioned malicious call search information memory area) Based on this, the called party is automatically called from the exchange.

On the other hand, the calling party number is retrieved from the front memory area, and a voice synthesis LSI or the like is activated to notify the calling subscriber number by voice to the above-mentioned called subscriber.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 shows an embodiment of the present invention in a space division type electronic exchange, and FIG. 2 shows memory information in the main memory of the exchange shown in FIG.

In Figure 1, SCN is a scanner, SD is a signal distributor, CP is a central processor, and MM
is the main memory.

In FIG. 1, a calling subscriber and a called subscriber are connected in a known manner by a route 0 through a call path switch and a call trunk, and are engaged in a call. In this case, to further explain the detailed billing as an example, the main memory M
Inside M, there is a detailed billing information memory area as shown in FIG. 2, in which information necessary for correspondence to call trunks, that is, correspondence to trunk numbers, is stored. During a call, 1 calling subscriber number, calling subscriber class 1 called subscriber number, called subscriber class and response time are stored.

In this state, if the called subscriber wants to know the calling subscriber's number because the calling subscriber is a malicious subscriber such as a threat, the called subscriber can use hooking (telephone hook switch). press briefly). The call trunk detects this hooking and communicates it to the central processor CP at the scanner SCN in a known manner. The following is the core of one embodiment of the present invention. The CP stores the fact that there is a malicious call notification instruction in the corresponding trunk number area of the detailed billing information memory area in the main memory MM, as shown in FIG. At this time, it is checked whether the called subscriber class, which is already stored in memory, is a class that can receive malicious call notification service, and only if the class can receive malicious call notification service, the above-mentioned malicious call notification instruction is stored. As a result of the comparison, if the subscriber class cannot receive the malicious call notification service, the above-mentioned malicious call notification instruction is not stored. When the call ends, the call end time is memorized in the area of the corresponding trunk number in the detailed training information memory area, and the entire information in the corresponding trunk number memory area is transferred to the magnetic tape device output information memory area in order to output detailed billing information. Move to. In one embodiment of the present invention, furthermore, at the time of termination of the call, it is checked whether or not a malicious call notification instruction is stored in the memory corresponding to the trunk number in the detailed billing information memory area, and if it is stored, The trunk number, calling subscriber number 2 and called subscriber number are picked up and moved to the malicious call search information memory area.

Based on the instructions in the malicious call search information memory, the called subscriber is then automatically called and the calling subscriber number is notified by voice to the called subscriber. Although the method of automatic calling and automatic voice notification itself is a known method, the automatic calling and automatic voice notification based on the malicious call search information memory extracted from detailed billing information is according to an embodiment of the present invention. First, based on the called subscriber number in the malicious call search information memory, the exchange calls the subscriber, and as shown in Figure 1,
The notification device and the called party are connected through the route. One way solution 2
The calling subscriber number in the malicious call search memory shown in the figure is inputted into the automatic voice editing device under the control of the CP from the MM in FIG.
56-7890" etc., is transmitted to the called party by voice via the notification device and route (2).

Note that the notification device shown in FIG. 1 has trunk functions such as calling a called subscriber and monitoring a called subscriber.

According to this embodiment, when a subscriber receives a malicious call such as a threatening call from a malicious person, or by making a
Immediately after the end of the call, you will be able to receive a voice notification of the malicious subscriber's phone number.

In the above embodiment, an example was described in which the present invention was implemented in a space-divided electronic exchange, but the present invention can be similarly implemented in a digital exchange or an electromagnetic exchange.

In addition, 1. An example of using detailed billing information will be described. 6. Calling subscriber number, called subscriber number, class information, etc. are information that even exchanges that do not perform detailed billing essentially have. The present invention is not limited to exchanges that perform detailed billing.

And, although the example in which the called subscriber transmits a malicious call notification instruction by fuv king is described, any other method may be used as long as the semantics are determined in advance, such as dialing or multi-frequency signals.

〔Effect of the invention〕

According to the present invention: - When a subscriber receives a call from a malicious party such as a threat, the subscriber can receive a voice notification of the malicious subscriber's number immediately after the call ends. As a result, it is possible to provide services that are attractive to subscribers, and there is no need for the switching center to manually search for malicious calls as in the past, which has the effect of reducing personnel costs.
