2. Description of the Related Art A network service control node that constitutes an intelligent network provides a variety of communication services such as an automatic call charging service, a toll-free service, a Q2 service, and the status of execution of each of these communication services. Traffic information that is statistically shown is being collected. The collection of the traffic information is conventionally limited to the collection of the traffic statistical information fixedly determined by the system.

As described above, in the conventional traffic information collection technique, the traffic information that can be collected is fixed in advance in the system, and the traffic statistical information of the new communication service desired by the customer or the network operator is obtained. It was difficult to collect. In order to dare to collect such new traffic information, it is necessary to add a function to the system program, and it takes an enormous amount of time and money from the generation of the collection request to the realization of the collection. Note that traffic management in a network is described in, for example, pages 2050 and 2051 of "Electronic Information and Communication Handbook" edited by The Institute of Electronics, Information and Communication Engineers (1988, Ohmsha).

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the configuration of an intelligent network system provided with a network service control node equipped with the traffic information collecting system of the present invention. In FIG. 1, 10a,
10b is an exchange that can be connected by common line signaling
a and 11b are communication terminals accommodated in the exchanges 10a and 10b, 20 is a network service control node that applies a communication service corresponding to a request from the communication terminals 11a and 11b, and 30 is a service that performs network management of the entire network. A management / operation device 40 is a service generation environment for generating a service logic program (SLP) used to execute each communication service.

In the network service control node 20, an SLP execution control function unit 21 that executes an SLP corresponding to a communication service in response to a service activation request from the exchanges 10a and 10b, and a service generated by the service generation environment 40. SLP2 downloaded from the management / operation device 30
A management function unit 22 for storing 2a and a traffic information generation function unit 23 for generating traffic information according to the present invention are provided. Each time the SLP for the communication service requested by the communication terminals 11a and 11b is activated, this SLP
The SLP execution control function unit 21 instructs the traffic information generation function unit 23 to control the counter according to the traffic information generation procedure described in
Traffic information for each communication service requested from the communication terminals 11a and 11b is generated.

In particular, the traffic information generation function unit 23 in this example comprises a traffic counter management function unit 23a, and this traffic counter management function unit 23a generates traffic information. That is, the traffic counter management function unit 23a has a counter 23b for each request item accessed by SLP (described as "CNT" in the figure).
Corresponding counter 2 based on an instruction from the SLP.
3b is counted, and the counted counter value is held as traffic information. The network service control node 20 uses the counter values held by the traffic information generation function unit 23 periodically or in the service management / operation device 30.
The service management / operation device 30 is notified by an instruction from the user.

The operation of collecting traffic information when performing service control of a certain service in the network having such a configuration will be described below with reference to FIG. Figure 2
It is explanatory drawing which shows the operation example based on this invention in the intelligent network in FIG. First, the communication terminal 11a requests the exchange 10a to start a service by using certain specific dial information. With this as an opportunity,
The exchange 10a sends the network service control node 20
Request to start service control.

The network service control node 20 uses the SLP execution control function unit 21 in advance to manage the service management / operation device 3
The execution of the SLP 22a downloaded from 0 and stored in the SLP management function unit 22 is started. SLP22a
Is a program that includes logic for controlling individual services, and is associated with the execution of the SLP 22a.
By transmitting the operation control instruction of 0a from the SLP execution control function unit 21 to the exchange 10a, service control in the intelligent network is performed.

Here, consider a case where it is desired to count the occurrence of a specific trigger depending on the service specifications, for example, when the telephone number of the communication terminal 11a on the calling side indicates that it is within a specific area. In such a case, the SLP 22a checks whether or not the trigger has occurred, that is, in the above-mentioned case, whether or not the upper digit of the telephone number of the communication terminal 11a on the calling side matches the specific numeral string. If they match, a specific counter in the traffic counter management function unit 23a according to the present invention is designated and updated. The designation of the specific trigger depending on the service specification and the designation of the counter to be updated are all performed by the program in the SLP 22a.

As described above, in the network service control node 20 of the present example, when collecting traffic statistical information that needs to be collected for each of various services, each SLP is
Allocate some counters and set the counter control to S
By programming the LP itself, the collection of traffic information that depends on various service specifications can be performed by the SLP.
Can be achieved by programming. Then, the counter update characterized by the communication service is updated by the SLP.
Since it can be realized by the instruction from 22a, it is possible to immediately respond to the change of the traffic data collection condition or the addition of the collection item without affecting the system program of the network service control node 20.

On the other hand, in the network service control node 20, the counter values of all the counters held in the traffic counter management function unit 23a are set at fixed cycle times, or at a specific time or when the maintenance operator designates them. , Service management / operation device 30. Since the service management / operation device 30 previously receives from the service generation environment 40 information regarding from which SLP and from which SLP each counter is updated at the time of SLP generation, the service management / operation device 30 has a unique condition for each service. The matched traffic information can be obtained.

As described above with reference to FIGS. 1 and 2, according to the traffic information collecting system of this embodiment,
Since the SLP instructs the update of the counter characterized by the service, it is not necessary for the system program of the network service control node 20 to be aware of the update condition of each counter, and the system program of the network service control node 20 can be deployed. It is only necessary to determine the total number of counters that can be used by these SLPs as a system operating condition based on the number of SLPs to be set, and to notify the service management / operation device 30 of the values of those counters. good.
Then, the counter update condition can be changed or added only by adding or modifying the SLP.

Further, the system program of the network service control node 20 need only have a function of notifying the higher-level service management / operation device 30 of the traffic information generated by the SLP, and the update condition of the individual traffic information. There is no need to be conscious of such things. The present invention is not limited to the embodiment described with reference to FIGS. 1 and 2, and various modifications can be made without departing from the scope of the invention. For example, in this example, one service management / operation apparatus 30 manages one network service control node 20, but one service management / operation apparatus 3
A configuration in which a plurality of network service control nodes are connected and managed by 0 may be used.
