Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network traffic collection system for a telephone switching network using a common signaling system. Assuming that the packet switching network will spread nationwide, it is about to be established in the telephone switching network as well, in which a network using the common line signaling system is constructed between the switching equipment, the transmission line, and the subscribers. FIG. 4 shows a system configuration example of the common line signaling system.

In the figure, 31 is a group switching system (source GC),
32 is a relay exchange (ZC # 1), 33 is a relay exchange (ZC # 1)
2), 34 is a destination switching system (destination GC), and 35, 36 are signal relay stations (STP). The solid line indicates the transmission line between the exchanges, and the dotted line indicates the common line for transmitting the call control signal of the exchange. The originating group exchange 31 is activated by the call from the calling subscriber A, and the originating group exchange 31 sends call control information to the signal relay station 35 through a common line, connects a transmission path to the relay exchange 32, and is common in the relay exchange 32. The line sends the call control information to the signal relay station 35, and connects the transmission path to the transit exchange 33. In the repeater exchange 33, the call control information is sent to the signal relay station 36 through the common line,
The transmission line to 34 is connected, the destination switching center 34 is activated, and the destination subscriber B is connected. When the call ends, a call control signal is sent from the destination switching center 34 to the signal relay station 36 via the common line, and a call control signal from the originating group switch 32 is sent to the signal relay station 35 via the common line, and the restoration completion signal is sent to each. The transmission lines to the repeater exchanges 33 and 34 are released.

As described above, in the common line signaling type telephone exchange network, the transmission line between the exchanges and the call control of the exchanges are controlled by the common line between the signal relay station and the exchanges to improve the use efficiency of the transmission lines. And effective processing of traffic control is required. For this reason, it is necessary to collect traffic for the exchange, the transmission line, and the telephone exchange network as a whole between the subscribers.

[0004]

2. Description of the Related Art Conventional traffic collection methods mainly set traffic items for calculating exchange equipment.
Closed traffic measurement items are set in the switching equipment such as the call volume, usage rate, number of calls for the entire system, number of calls connected to the system, etc. Such traffic information is measured by the traffic counter of each exchange.

A connection configuration diagram of a conventional traffic collection method is shown in FIG. The figure shows the method of collecting traffic information on the transmission network. In the figure, 21 is the originating GC switch, 22 and 23 are ZC switches (relay stations), 24 is the receiving GC switch, and 25 and 26 are STP.
(Signal relay station), 27 is LS traffic center, 28 is TS
Indicates a traffic center. The traffic information of the transmission network is collected such that the traffic counter information of the GC exchanges 21 and 24 is concentrated at the LS traffic center 27 via the STPs 25 and 26 at regular intervals, and the traffic counter information of the ZC exchanges 22 and 23 is uniform. The data is aggregated in the TS Traffic Center 28 every fixed time.

Since these pieces of traffic information are closed in the exchange equipment, it is not possible to measure where the originating call originates, through which exchange and where and how much. For this reason, it is possible to bring in the traffic information of all stations to process, edit, and grasp the route and volume from the call origination to the end of the call, but it will be a huge amount of data and it is expected that the calls will not be handled between the exchanges. Became,
There were problems such as inaccuracy and it was difficult to put it into practical use.

[0007] Further, the conventional traffic observation is mainly the traffic observation corresponding to the system, and the total number of calls as a whole system and the number of calls for each service are customary. Therefore, habits, serviceability, traffic volume, etc. for subscribers cannot be collected in detail, and there is a problem that they cannot be used for equipment planning according to the service.

Further, as a related problem, since the traffic control side does not know the route and quantity of the call, it is impossible to measure the effect of control and the degree of influence of the entire network. Therefore, effective traffic control including the transmission line is possible. Is impossible.

[0009]

As described above, the conventional traffic observation is the traffic observation closed to the exchange for calculating the exchange facilities, and the traffic observation corresponding to the system is mainly used, so that the traffic observation corresponding to the subscriber is performed. However, there was a problem with effective traffic control including the transmission line.

It is an object of the present invention to solve the above-mentioned conventional problems by a traffic measurement method which enables traffic monitoring, control and planning of the entire telephone switching network (switch, transmission line, subscriber). .

Reference numeral 8 indicates a packet switching network. Solid lines indicate transmission lines, and dotted lines indicate common lines. A traffic observation node is provided in each exchange and signal relay station so that the traffic information added to the call control signal on the common line can be monitored.

In the originating switchboard 1, the originating switch information and the originating switch incompletion information are added as traffic information to the call control signal of the common line to the signaling relay station 5, and in the repeating switch 2 the common line to the signaling relay station 5 is added. Relay switch information is added as traffic information to the call control signal, relay switch information is added as traffic information to the call control signal of the common line to the signal relay station 6 in the relay switch 3, and the signal is relayed in the termination group switch 4 at the end. The destination switch information is added to the call control signal of the common line to the station 6 as traffic information and is collectively sent as one call information. In the signal relay stations 5 and 6, the traffic information is sequentially extracted and stored from the common line call control signal from each station, and the stored traffic information is transferred to the processing center 7 via the packet network 8. The processing center 7 is configured to collect, accumulate, statistically and analyze the traffic information for each call extracted by the signal relay stations 5 and 6 in real time.

[0013]

The function of the exchange according to the present invention has the following three points. (1) Provide a common line signal monitor function in the signal relay station (STP). As a method of using the existing call control signal, a function of referring to existing control signals (subscriber ID, SUB class, start time, exchange ID, etc.) flowing between stations to monitor traffic information in the exchange network. In addition to the above functions, the switch adds traffic information to monitor traffic information in the switching network. (2) A call-supporting assembling function is provided in the exchange and the signal relay station.
A function that manages a call control signal (for example, a correspondence between a calling signal and a disconnection signal) that can be determined by associating a common line signal from calling to disconnection as information completed as a call. This corresponding function can be shared by the exchange and the signal relay station. (3) Provide a traffic collection / storage function in the signal relay station (STP). A function that accumulates the information collected for each call.
