Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to a switching equipment system that prevents discrepancies in information on the number of switching equipments managed by a plurality of switching equipments and a traffic information collection management device, and updates the information in real time. It is related to numerical information management method.

(Prior Art) Conventionally, information on the number of switching equipment has been created, changed, added, etc., and managed independently by the switching equipment, an observation device externally attached to the switching equipment, and a traffic information collection management device.

Also, patent application No. 59-05884 filed prior to this application.
In No. 1 (station information input method), a traffic monitoring device was installed externally to the exchange to collect traffic information from the exchange, and was connected to the scanning circuit via the busy lead of each trunk.

(Problems to be Solved by the Invention) Conventionally, information on the number of switching equipment has been independently created, changed, added, and managed, so that discrepancies in the information on the number of switching equipment tend to be prolonged and latent.

In addition, the above-mentioned patent application No. 5, in which a device for observing traffic is arranged and connected to the scanning circuit via the busy line of each trunk.
In No. 9-058841, traffic observation had to be temporarily suspended when the information on the number of switching equipment was changed.

An object of the present invention is to provide a switching equipment number information management system that solves these drawbacks.

(Means for Solving the Problems) The present invention includes a plurality of exchanges having a traffic information measurement function and a traffic information collection device that collects and manages traffic information. An information transfer device that transmits information on the number of switching equipment to the traffic information collection and management device is installed in each of the switching equipment. The traffic information collection device has an information transfer device that requests and receives information on the number of switching equipment of each switch from each switch.

(Function) The information transfer device in the exchange is a device that transmits and receives information necessary for inter-station connections with adjacent stations during switching operation, and uses its functions to transmit traffic information such as the number of calls by TGN and the exchange equipment. This information is transferred to the toshi trunk number traffic information collection device for each TGN.

The traffic information collection device performs processing necessary to manage traffic information based on information on the number of exchange equipment transferred from the exchange via the information transfer device.

! In addition, in the traffic information collection device, when an abnormality is detected in the information on the number of switching equipment, and at regular intervals, the information transfer device transmits a switching equipment number request signal to each subordinate switching equipment.

The information on the number of exchange equipment is transferred to the traffic information collection management device without interrupting the traffic information transfer, and the traffic information collection management device requests the information on the number of exchange equipment from the exchange at regular intervals and when restarting due to system down etc. Receive.

(Example) FIG. 1 is a diagram for explaining the present invention in detail, and a switching equipment number information management system will be explained using this diagram. As for the collected traffic information, the number of calls for each TGN shall be measured.

In FIG. 1, the communication path control device spc performs exchange operations based on the operating status of the network-installed link TRK, etc., managed on the memory IJMM under program control stored in the memory memory IJMM of the central processing controller CC. It has been realized. Furthermore, traffic observation can be easily realized from the management information on the memo IJMM. Since storage program control is a well-known technique, detailed explanation will be omitted. The information transfer device C8E is a device that transmits and receives information necessary for inter-office connections with adjacent stations in switching operations, and uses its functions to transmit and receive information such as the number of calls by TGN and switching equipment, which are traffic information accumulated on the memo IJMM. Toshitrunk number traffic information collection device 2 by TGN, which is number information
Transfer to.

Now, as shown in Fig. 2, the number of trunks Σ of TGNa,
N, (t) to the number of trunks of TGN at ΣNm(t)
The trunk has been implemented and the information is in the memo IJ
Assuming that it is stored in the MM, the exchange 1-j records the number of uses of all operable trunks at the same time as the system startup.
, (t) when the trunk is released (when the call is disconnected), and the observation is started by adding "1" to (t). The trunk use count αj(1) is transferred to the traffic information collection device 2 as traffic information for each TGN at the same time when t minutes have elapsed. In addition, the number Nj of operational trunks compatible with TGNai at this time is also transferred as information on the number of switching equipment. From then on, the above operation will be repeated every minute, but regarding the information on the number of switching equipment, the number of operable trunks will be changed due to failure, maintenance, etc.
The number of trunks is transferred only when the number of trunks decreases due to operational reasons, or when the number of operable trunks increases due to restoration of failed trunks, maintenance, operational reasons, etc., and is not transferred at other times.

In this storage programming control system exchange,
Regarding changes in switching equipment (increase/decrease in operating trunks),
Because it is carried out in a memorandum-based manner, it does not affect other switching equipment in operation.Because it can be carried out, traffic information observation and transfer can be done without relaying.

Next, in the traffic information collection device 2, the exchange 1-
1. ..., TGN for t minutes transferred from 1-n
By multiplying the number of separate trunk usage ΣNj(t) (number of separate TGN calls) by the number of trunks that can be operated at that time αj(1), the number of separate TGN calls 1ΣN4(
t)・α,(t) can be calculated by dividing the number of uses ΣNJ(t) by the number of operable trunks αj(1). Toshi trunk usage efficiency by TGN Nj(t)/α
j(1)) can be calculated.

Unfortunately, multiple exchanges under the traffic information collection device are synchronized.
By adding up the number of trunk usage by TGN and the corresponding number of operational trunks, and dividing the number of trunk usage by the number of operational trunks, the traffic information collection device 2 calculates the exact trunk usage efficiency by TGN. can be calculated. The above provides extremely useful information for countermeasures against congestion in switching networks and for calculating the optimal number of equipment (number of trunks per TGN) for switching network configuration when constructing a switching center.

By the way, during the operation of the traffic information collecting device 2, if a system failure occurs while changing the information on the number of switching equipment, or due to failure to detect an error in information transfer, etc., the information on the number of switching equipment in the traffic information collecting device may be incorrect. It is unavoidable that the situation is no longer guaranteed. Therefore, in the present invention, in order to take immediate countermeasures against the above-mentioned problem, when the traffic information collection device 2 detects an abnormality in the switching equipment information and at regular intervals, the traffic information collection device 2 sends information to each subordinate switching equipment 1- 1. . . . transmits a request signal for the number of exchange equipment to 1-n. Then, the exchange that has received the signal promptly sends the latest information on the number of its own exchange equipment to the traffic information collection device 2.

(Effects of the Invention) By transferring information on the number of exchange equipment from the exchange to the traffic information collection device when necessary, it is possible to prevent mismatches in the information on the number of exchange equipment in the exchange and the traffic information collection equipment and their long-term potential, and to prevent the inconsistency of information on the number of exchange equipment in the exchange and traffic information collection equipment, This has the advantage that the large amount of information on the number of switching equipment, which was previously created by each switching equipment and traffic information collection device, can be created by only the switching equipment, and the information can be centrally managed.

Note that the call count traffic information by TGN is a typical example of traffic information handled by the present invention, and in addition to this, the call count traffic information by TGN is a typical example of traffic information handled by the present invention.
We also collect and manage traffic information such as 5C-RC usage efficiency, various transaction call volumes, number of calls by call type, number of calls by restriction code, number of calls by region, number of calls by TGN and number of calls by region, and number of transmissions and receptions by signal type. There is.
