Description

[Detailed Description of the Invention] The present invention is based on a common control type automatic telephone exchange≠a designated auditing method in which an operator arbitrarily specifies and extracts only those audited calls that are subject to auditing in a telephone service auditing system in rural Europe. It is related to.

The purpose of the currently implemented telephone service audit system is to investigate the service quality of automatic telephone exchange machines to customers and to provide necessary guidelines for various measures to maintain and improve service quality. In such service audits, there are cases in which an unspecified number of subscribers are audited randomly without distinction of connection type, such as connections within the local station, connections outside the target station, special numbers, etc., and cases in which a specific connection type specified by the operator is audited. There are cases where By the way, an example of a telephone service inspection system in a conventional automatic telephone exchange using a shared control system will be explained with reference to FIG.

In the figure, SUB is the originating subscriber, SWF is the switch frame that creates various communication paths, OGT is the outgoing trunk, OR is the originating register, CM is the connection marker, and OBSE is the auditing device that extracts and processes the information necessary for service auditing. , its operation is as follows. When the originating subscriber SUB requests an originating connection, the originating subscriber SUB and the originating register OR are connected via the switch frame SWF by a known method of originating connection.

On the other hand, when the originating register OR is connected to the originating subscriber SU, the auditing device OBSE is activated.

As for the operation of the exchange, the outgoing register O is
Activate the connection marker CM at R, transfer the necessary connection information, perform the necessary processing in the connection marker CM, drive the switch frame SWF, and close the communication path between the originating subscriber SUB and the outgoing trunk OGT. do. During this time, the auditing device OB
The SE inspects and receives the subscriber's dial selection information from the telephone line of the subscriber terminal, and also receives various means such as audible signals, responses, and disconnections by inspecting the telephone line, and organizes them according to established processing procedures. Finally, it determines whether the call is completed, whether the subscriber is busy, etc., and records it.

However, with the recent expansion of telephone networks and the diversification of social life, more detailed audit data than before has become necessary. A function that allows the operator to arbitrarily specify only specific audit calls by group has become unnecessary.

The present invention has been made in view of the above-mentioned needs, and it is an object of the present invention to provide a designation method for extracting only those audit calls that are arbitrarily designated by an operator and are subject to audit.

The drawings will be explained in detail below. 2 and 3 show an embodiment of the present invention, in which SUB represents an originating subscriber, SWF represents a switch frame for creating various communication paths, and FIG.
OGT is the outgoing trunk, SPOR is the special transmission register,
In addition to the function of receiving dial pulses from the calling subscriber SUB, it has information storage units 1-1 and 1-2 for other necessary information such as calling subscriber accommodation location information and connection type information. It has a special function that later transfers the information to the trunk for self-auditing.

Note that even if this special transmission register SPOR receives recovery information from a connection marker CM, which will be described later, it does not recover and prepares for connection between the originating subscriber SUB and the outgoing trunk OGT. CM is a connection marker, OBST is a trunk for auditing, and consists of an information receiving section 2, a verification circuit 3, an information specifying section 4, and an output section 5, and the information receiving section 2 receives information transferred from the special transmission register SPOR. Then, the verification circuit 3 collates the specified audit information set in advance in the information designation section 4, and outputs the result to the output section 5. Next, the operation will be explained.

When the originating subscriber SUB requests an originating connection, the originating subscriber SUB is connected to the special originating register SPOR via the switch frame SWF by a known method of originating connection. Thereby, the special transmission register SPOR checks whether the audit trunk OBST is empty or not, and if it is empty, captures the audit trunk OBST. When the audit trunk OBST is captured, the special outgoing register SPOR
When the connection marker CM is captured, the trunk number or trunk accommodation position information set in advance from the audit trunk OBST is sent to the special transmission register SPO.
At the same time, other necessary information such as calling subscriber accommodating location information and connection type information is also transferred from the special call register SPOR to the connection marker CM via R. Outgoing subscriber SUB and audit trunk O via frame SWF
BST is designated connected. When the connection operation is completed, the connection marker CM enters a recovery operation and transfers recovery information to the special transmission register SPOR.

On the other hand, the special transmission register SPOR does not recover even if it receives the recovery information as described above, and prepares for connection between the originating subscriber SUB and the outgoing trunk OGT. First, special transmission register S
The POR receives and stores the dial selection information from the calling subscriber SUB, and when preparations for reacquisition of the connection marker CM are completed, the dial selection information and the information are stored in the information storage units 1-1 and 1-2 from the special call register SPOR. The connection marker CM transfers various necessary information such as location information of the calling subscriber and connection type information to the connection marker CM, and uses a known method to drive the switch frame SWF to connect the calling subscriber SUB and the outgoing trunk OGT. close the communication path.

Therefore, in this case, the audit trunk OBST and the outgoing trunk OGT are connected in parallel from the originating subscriber terminal via the switch frame SWF, and the audit trunk OBST-switch frame is connected as a service audit route. The information necessary for service auditing can be extracted via the SWF-originating subscriber SUB terminal. In such a situation, if a designated audit is to be carried out, designated audit data set in advance by the operator is designated in the information designation unit 4 provided in the audit trunk OBST. Note that the designation means may be manual or automatic designation by remote control. As an example, let us consider the case where subscribers accommodated in the ingress switch frame of the switch frame SWF are audited in units of frames.
The operator sets the frame numbers FG and FN of the target ingress switch frame in advance, and specifies them using the information specifying section 4 of the audit trunk OBST. When the calling subscriber SUB starts calling, the special calling register SPOR is captured by the calling connection as described in the operation explanation above, and the special calling register SPOR sends the incoming switch frame of the calling subscriber SUB using a known method. The subscriber accommodation location information is received and stored in the storage section 1-1.

On the other hand, the audit trunk 0 is sent from the special transmission register SPOR.
The existing T is captured and the calling subscriber accommodating position information stored in the special calling register SPOR is transferred, and this special report is received by the information receiving section 2 of the audit trunk OBST. Here, the information designated by the information designation part 4 is compared with the verification circuit part 3, and if both pieces of information match each other, it is determined as a target audit call, and the audit trunk OBST is sent to the originating subscriber SUB. Connect and continue audit control. Further, if the comparison results do not match, it is determined that the call is not the intended audit call, and the audit trunk OBST is restored and audit control is omitted. Further, in the embodiment described above, the special transmission register SPOR and the auditing trunk OBST are provided separately, but these devices may be combined into one.

In this way, when a specified audit is performed using subscriber accommodation position information in an incoming frame, audit data can be collected in incoming frame units, and audit data can also be obtained in specific subscriber units by the specified method. Additionally, in the past, audit points were periodically changed manually to maintain the accuracy of audit data.
However, by implementing the method of the present invention, it is possible to automatically collect audit data from the target audit point by easily changing specified information, and it is also possible to save a lot of labor. Effects can be obtained. As explained above, the present invention has a means for arbitrarily specifying the information alone or in combination by receiving various information necessary for specified audit from the information source of the exchange. It is now possible to arbitrarily audit services for various patterns, such as by input frame, connection type, and time zone with time information, and it is possible to obtain more detailed audit data than the conventional method, and is more efficient. The effect is immeasurable because it can be implemented in many ways.
