Abstract

PURPOSE:To relieve the quantity of load of the maintenance personnel by automating the link setting job with all exchange nodes under the control of a sub service control node at the extension of a sub service control node. CONSTITUTION:A notice means of a number of exchange nodes 110 under the control of a sub service control node 105 relating to itself is provided in a main service control node 101 and a communication means with the main service control node 101 is provided in the sub service control nodes 105. Then the processing setting a link to all the exchange nodes under the control is executed by allowing the extended service control node to inquiry about a list of the exchange node numbers under the control to the main service control node at the extension of the sub service control node. Thus, a job for exchange nodes under the control to set a link is not required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control method when adding nodes in an intelligent network.

[Prior Art] In a conventional intelligent network, a service control node consists of a main service control node that is uniquely determined for each switching node, and a secondary service control node that is arbitrarily assigned to each switching node for each call. was not stratified. Therefore, when adding a service control node, it was necessary to set up links from all subordinate exchange nodes to the added service control node. As an example of such an intelligent network, NTT Research Practical Application Report, V
OL 38. No. 41989 ``Advancement of r-networks and future trends''.

[Problems to be Solved by the Invention] The above-mentioned conventional technology does not take into account the link membrane chamber method for expansion nodes, and when adding a service control node, it is necessary to set links for the expansion nodes at all subordinate exchange nodes. It required

An object of the present invention is to automate the link setting work for the expansion node in all subordinate exchange nodes when a service control node is expanded.

[Means for Solving the Problem] The above purpose is to provide a main service control node that is uniquely determined for each switching node and a secondary service control node that is arbitrarily assigned to each switching node for each call. and within the main service control node,
This is achieved by providing means for notifying the subordinate switching node number and the switching node number of the sub-service control node to which it corresponds, and providing means for communicating with the main service control node within the sub-service control node.

Furthermore, the above purpose is to hierarchize multiple service control nodes into a main service control node that is uniquely determined for each switching node and a subservice control node that is arbitrarily assigned to each switching node for each call. This is achieved by providing within the service control node a means for notifying the subordinate switching node number of the sub-service control node to which it corresponds and the subordinate switching node of the sub-service control node number.

[Operation] When adding a sub service control node, the added service control node can execute the process of setting links for all subordinate exchange nodes by inquiring the main service control node for a list of subordinate exchange node numbers. This eliminates the need to set up links.

In addition, when adding a secondary service control node, the main service control node can perform the process of setting up links for all subordinate exchange nodes by notifying the subordinate exchange nodes of the expansion node number, so the links can be set at the subordinate exchange nodes. This eliminates the need for additional work.

In FIG. 4, the basic service of simply connecting an originating subscriber and a terminating subscriber, as seen in conventional telephone services, is provided only by the switching node 409, but additional services (for example, call forwarding, Advanced communication services (such as three-way calls) are provided by sharing functions between the main service control node 401 and the sub-service control node 405. That is, the secondary service control node 405 is entrusted with service control by the switching node 409.

It analyzes and translates the service and issues instructions to the exchange node 409 regarding the connection details necessary to provide the service.

The switching node 409 interprets the connection details and sends the communication path device 41

In FIG. 4, after the sub service control node 405 is added, the sub service control node notification process 403 of the main service control node 401 is activated, and as shown in FIG. The replacement node 409 is notified of the addition of the sub-service control node (501), and the link setting processing program 413 of the replacement node 9 starts the node variable time limit processing 411 (502) and waits. When the time-limited processing times out, the link setting processing program 7 is activated for the additional sub-service control node 405 based on the information (503). The link setting processing program 407 of the additional secondary service control node 405 executes link setting processing according to the link setting processing program 413 of the exchange node 4.9.
