DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conflict judging method between an IN service and a non-IN service of various communication services provided in an intelligent network (hereinafter referred to as IN).

[0002]

2. Description of the Related Art Conventionally, conflict determination for non-IN services has been realized by a service operation function electronic exchange, and conflict determination for IN services has been realized by providing an electronic exchange controller with a dedicated processing function.

[0003]

In the conventional conflict determination method, the non-IN service and the IN service are determined by the service operation function electronic exchange or the electronic exchange control device, respectively. Non-I
In providing the N service and the IN service at the same time, it has been difficult to determine the conflict.

[0004] Further, since the service operation function electronic exchange controlling the non-IN service and the IN service is different, each time the conflict determination processing is executed, service attribute information is transmitted between the service operation function electronic exchanges. Therefore, there is a problem that the telephone exchange processing capacity and the connection delay time per unit time exceed the practical range.

[0005]

According to the conflict judging method of IN service and non-IN service of the present invention, a service operation function electronic exchange for performing telephone exchange processing and an electronic signal line connected to the service operation function electronic exchange. Competition determination between IN service and non-IN service when simultaneously providing IN service realized by an electronic exchange control device for performing telephone exchange and non-IN service realized by an electronic switching network having a plurality of service operation function electronic exchanges A service operation function for mutually transmitting service attribute information of factors competing in providing a plurality of services between the service operation function electronic exchange and the electronic exchange control device, and detecting a change in the service provision status. At this point, any one of the service operation function electronic exchange and the electronic exchange control device becomes independent. And executes a contention determination process of whether an acceptable change in-bis providing situation.

[0008] The factors competing in providing the plurality of services include a charging condition, a signal transmission / reception method, and a connection condition of the service to be provided.

The service operation function electronic exchange controls a first signal transmission / reception unit for transmitting / receiving the service attribute information to / from the electronic exchange control device via the electric signal line, and controls a connection operation of a non-IN call. A non-IN call control unit,
A first contention determination unit for determining whether or not the change in the service providing state is acceptable; wherein the electronic exchange control device includes the service operation function electronic exchange and the service attribute information via the electrical signal line. A second signal transmission / reception unit for transmitting / receiving data, an IN call control unit for controlling a connection operation of an IN call, and a second contention determination unit for determining whether or not the change in the service providing state is allowable. When a new non-IN service provision request is issued to a communication device while an IN service is being provided to a certain communication device, the service attribute information of the IN service determined by the electronic exchange control device is transmitted to the electronic exchange control device. When the IN service is started to be provided from the exchange control device to the service operation function electronic exchange, the IN service is handed over to the service operation function electronic exchange. The first conflict determination unit performs a conflict determination based on the service attribute information of the non-IN service and the service attribute information of the IN service when requesting the provision of the non-IN service, and is providing the non-IN service to a certain communication device. When a new request for providing an IN service is issued to the communication device, the service operation function electronic exchange changes the service attribute of the non-IN service when making a request for providing the IN service to the electronic exchange control device. The second contention determination unit of the electronic exchange control device performs the contention determination between the non-IN service and the IN service by delivering the additional information as additional information.

[0021]

As described above, according to the present invention, in various communication services provided by the IN system, service attribute information determined by the electronic exchange control unit and service attribute information managed by the service operation function electronic exchange are provided. Since the information is mutually communicated and held according to the change in the service provision status, the service operation function of the electronic exchange or the electronic exchange control device independently determines the conflict between the non-IN service and the IN service. This makes it possible to minimize the transmission and reception of information in the provision of the IN service, and has the effect of reducing the connection delay time required for contention determination.
