2. Description of the Related Art As a configuration of a service control node in an intelligent network, for example, "public network switching service software" (Journal of the Institute of Electronics, Information and Communication Engineers V.
ol.74, No.2, pp.121-124 (1991)) are known. By the way, the service control node in the intelligent network can predict the required subscriber accommodation capacity or processing capacity in order to realize various services by one node,
Generally, it is often difficult. In order to solve this difficulty, for example, by adopting a function distributed configuration with a plurality of types of devices, each type of device also has a load distribution configuration that allows the number of devices to be increased or decreased according to the required performance, It is possible to construct a flexible service control node. When the input / output signal control device or the service control execution device accesses the service data of a specific user, if it is stored in any of the service data management devices existing in plural units, It may be considered that the input / output signal control device or the service control execution device, which is the access source, specifies the service data management device of the storage destination by using the information and directly accesses the corresponding service data management device.

[0003]

However, in the above-mentioned technique, it is necessary for the input / output signal control device or the service control execution device to be aware of the configuration and data management division of the service data management device which exists in plural units. become. Further, in such a configuration, since it is necessary to add a service data management device as the number of accommodated subscribers increases, as described above, the input / output signal control device or the service control execution device can store the service data for each user. When managing which of a plurality of service data management devices is stored, a change in the configuration on the service data management device side always affects the input / output signal control device or the service control execution device. Occurs.
The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems in the prior art and execute an input / output signal control device or service control that employs the above-described load balancing configuration. An object of the present invention is to provide an operation control method within a service control node in which the device does not need to be aware of what kind of service data is stored in each of the plurality of service data management devices.

[0004]

The above object of the present invention is to provide an input / output signal control device having a plurality of load distribution configurations, a service control execution device having a plurality of load distribution configurations, and a plurality of load distributions. A method for controlling operation in a service control node having a service data management device having a configuration, for identifying a service data management device that manages service data of the user from a user identifier in each of the service data management devices. Of the service data management device that manages the directory of the user and receives a request to access the service data of a specific user, identifies the service data management device that manages the service data of the user by referring to the directory, and specifies the service data management device. A service control node for transferring the access request to a service data management device Operation control method, or is accomplished by the service control node operation controlling method characterized by returning the identifier of the specific service data management device to the requesting of the access request.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION When the I / O signal control device or the service control execution device accesses the service data of a specific user, the service data of the user is stored from the identifier of the user. By specifying the service data management device that is present and directly accessing the service data management device, the configuration and the data management sharing of the service data management device in which a plurality of input / output signal control devices or service control execution devices exist It is due to being aware of. Therefore, in the operation control method in the service control node according to the present invention, in each service data management device among the service data management devices existing in plural, the service data management device for managing the service data of the user from the user's identifier. Manages a directory for identifying the service data, and the service data management device that has received the access request to access the service data for a specific user identifies the service data management device that manages the service data of the user by referring to the directory. , The request is directly transferred, or the identifier of the specified service data management device is returned to the access request source, and the access request source sends the request to the target service data management device again Signal control device or service control execution device Without being aware of what service data are respectively stored in the bis data management apparatus, it is obtained by enabling transmits an access request to any service data management device. When the number of users or the number of service data management apparatuses themselves is increased or decreased, the number of users or the number of service data management apparatuses themselves is increased or decreased by changing or adding only the directory managed by each service data management apparatus. Even if the setting occurs, it does not affect the input / output signal control device or the service control execution device at all, and so-called distributed invisibility for a plurality of service data management devices can be realized.
