Field of the Invention The present invention relates to a connection system for searching for malicious calls from criminals in telephone networks. In recent years, there have been many cases in which telephones have been used in connection with crimes, such as the ability to intercept and record telephone calls from kidnappers, track the location of calls made by criminals, and eavesdrop on incoming calls made to specific surveillance subscribers. There is a growing need for telephone offices and telephones to have the following. In order to address these issues, the telephone network also has connection functions to track criminals. However, as telephone networks become wider in area, there are more and more cases in which a remote originating station is connected to a terminating station via a relay station.

あるためである。[Prior Art] In the current criminal tracking system, when a subscriber who has registered for monitoring in advance (monitoring subscriber) receives a request for an incoming call,
Since the system collects information at monitoring subscriber reception stations, there is a problem in that monitoring equipment must be installed at all stations. This is because it is necessary to write down the caller's number when connecting a monitoring tape recorder or typewriter for hooking a registered subscriber.

ある。[Problem to be solved by the invention] If monitoring and recording were the only means of monitoring malicious calls, it would have been possible to collect information at the destination station, but in the future it would be possible to combine it with a computer and instantly determine voiceprints. When it becomes necessary to introduce large-scale equipment, it is more cost-effective to install it at a specific small number of stations than to install it at the destination station (that is, at all stations).

, The processing procedure in the connection configuration of each embodiment will be explained with reference to FIG. (Example 1) The processing procedure of the connection configuration of Example 1 of FIG. 2(a) will be explained with reference to the processing flowchart of FIG. 3. (1) Subscriber A makes a call to subscriber B. (2) Upon receiving the call termination request from the originating station 11 to the B subscriber via the relay station 14, the terminating station 12 uses the subscriber type determining means to check whether the B subscriber is a monitoring subscriber. (3) If subscriber B is determined to be a monitoring subscriber, destination 1
The incoming line type is determined by the incoming line type determining means 2. (The incoming line type is either "general" or "monitored" for all incoming lines.)
This information is used to distinguish between calls, and "monitoring" is registered in advance only for routes for monitoring calls, and "general" is registered for other routes. ) (4) When the incoming line type is "general", the destination station 12 interprets that the connection request is not from the route of the monitoring station 13, and the originating station 11
The subscriber type signal of subscriber B (monitoring subscriber) is returned to the subscriber. In this case, incoming calls to subscriber B will not be accepted. (5) The originating station 11 that has received the subscriber type signal (monitoring subscriber) releases the route ■ to the destination station 12 via the relay station 14, and uses the pre-registered detour route registration table 17. A detour route ■ is determined by indexing by subscriber type. (6) The originating station 11 detours the connection route to the monitoring station 13 using the obtained detour route ■. (7) Furthermore, in order to notify the monitoring station 13 that the main call is a call that requires monitoring and needs to be distinguished from general calls, the originating station 11 sends a "monitoring request" signal in addition to the B subscriber number. is transmitted to the monitoring station 3. (8) The monitoring station 13 that received the “monitoring request” signal
The route of the subscriber is determined, and the subscriber number of subscriber B is sent to the determined destination station B as an incoming call request, thereby monitoring the relationship between subscriber A and subscriber B. (9) Terminating station 12, which received the call request to subscriber B, (
Similarly to 2), the subscriber type determining means checks whether subscriber B is a monitoring subscriber. (10) If subscriber B is a monitoring subscriber, the destination station 12 is (3
), the incoming line type is determined by the incoming line type determining means. (11) When the incoming line type is "monitoring", the destination station 12 interprets it as a connection request from the monitoring station detour route (3) and accepts the call to subscriber B. (12) The monitoring station 13 monitors the content of the call between subscriber A and subscriber B using the call content monitoring means. (Embodiment 2) In Embodiment 1, in order to identify whether a detoured call is a monitoring call or not, the monitoring station (station C) must install individual monitoring lines between all other exchanges. This would result in unnecessary installation of monitoring lines. Embodiment 2 is a system that does not require monitoring lines between all other exchanges and allows other stations to be monitored freely. Figure 2 (
The processing procedure of the connection configuration of Example 2 of b) will be explained. (1) 'Subscriber A makes a call to subscriber B. (2) The terminating station 12 that received the call request to subscriber B
Check whether the subscriber is a monitoring subscriber. (3) If subscriber B is a monitoring subscriber, the destination station 12 does not judge the incoming line type as in the case of the above-mentioned principle configuration, but uses the monitoring request judgment means to judge whether there is a "monitoring request". I decided to do so. (A "monitoring request" is a "monitoring request"
A signal meaning ``monitoring request'' is newly defined, and the ``monitoring request'' receiving station connects and releases calls based on this signal. ) (4)'If there is no "monitoring request", the subscriber type number (

(5) 'The originating station 11 that has received the subscriber type signal (monitoring subscriber) releases the route ■ to the destination station 12, as in the case of the configuration of the first embodiment, and seeks a detour route ■. (6) 'The originating station 11 detours to the detour route (2) to the monitoring station 13, as in the case of the configuration of the first embodiment. (7)'Furthermore, the originating station 11 transmits the subscriber number of subscriber B and a "monitoring request" signal to the monitoring station 13, as in the case of the configuration of the first embodiment. (8) The monitoring station 13 that received the 'monitoring request' signal
Find the subscriber's route, send the B subscriber number and a "monitoring request" signal to the found route (destination station B) as an incoming call request,
Monitoring between subscriber A and subscriber B is performed. (9) The destination station 12 that received the call request to subscriber B, (
2) Similarly to ', it is checked whether subscriber B is a monitoring subscriber. (10)' If subscriber B is a monitoring subscriber, the destination station 12
Similar to (3)', the presence or absence of a "monitoring request" is determined by the monitoring request determining means. (11)' If it is a "monitoring request", the destination station 12 interprets it as a connection request and allows the call to subscriber B. (12)' At the monitoring station 13, A
The contents of the call between the subscriber and subscriber B are monitored. (Example 3) In the above-mentioned Examples 1 and 2, it is assumed that the receiving subscriber B is the monitoring subscriber, but in this embodiment 3, the calling subscriber A is registered as the monitoring subscriber. is assumed. The processing procedure of the connection configuration of the third embodiment shown in FIG. 2(c) will be explained with reference to the processing flowchart shown in FIG. (1) "Subscriber A makes a call to subscriber B. (2)" In the calling station 11, the subscriber type determining means determines whether the calling subscriber A is a registered monitoring subscriber. (3) "If originating subscriber A is a monitoring subscriber, the originating station 11 seeks a detour route ■ without using the general route ■ normally used between subscriber A and subscriber B. (4 )”The originating station 11 returns to the monitoring station 1 according to the detour route
Detour to 3. (5)"Furthermore, the originating station 11 transmits the subscriber number of subscriber B and a "monitoring request" signal to the monitoring station 13, similarly to the process flow (7) of the first embodiment described above. (6) Upon receiving the “monitoring request” signal, the monitoring station 13 determines the route of subscriber B, and issues an incoming call request to the determined route.
The subscriber A and subscriber B are monitored by transmitting the B subscriber number and a "monitoring request" signal. (7) “The destination station 12 that received the call request to subscriber B
Check whether the subscriber is a called subscriber. (8) If subscriber B is the terminating subscriber, the terminating station 12 uses the monitoring request determining means to determine whether there is a ``monitoring request.'' (9) If it is a "monitoring request," the destination station 12 interprets it as a connection request and allows the call to subscriber B. (10)" The monitoring station 13 monitors the content of the call between the registered subscriber A and the called subscriber B by the call content monitoring means. (Application example) A connection configuration diagram of an application example of the present invention is shown in FIG. 6. shows a case where a detour route is provided for each service. In the figure, 21 is a departure station, 22 is a destination station, 23 is a monitoring station C, 24 is a monitoring station D, 25 is a monitoring station E, 26 is a general route, 27
, 28 and 29 indicate the respective detour routes. Subscriber A
When connecting from the originating station 21 to subscriber B at the destination station 22 via the general route 26, subscriber B has registered to receive different services C, D, and E, such as eavesdropping service, criminal identification service, special service, etc. In this case, detour routes 27, 28, and 29 are provided for each service, and monitoring station C
, D, and E, it is possible to receive a variety of services by establishing centers for each service. or subscriber A
It is also possible to receive a specific malicious call service by stopping at the monitoring station on a detour route without making a call between the subscriber and registered subscriber B.
