Call control system in an intelligent network
First Claim
1. A call control processing system in an intelligent network, comprising:
- a plurality of service switching devices, each includingconverting means for converting between a call number and a LEG identifier, wherein the call number identifies an outgoing call from a first subscriber accommodated in the corresponding service switching device to a second subscriber or the call number identifies an incoming call to the first subscriber accommodated in the corresponding service switching device from the second subscriber, and wherein the LEG identifier is commonly recognizable by the plurality of service switching devices,a first CONNECTOR management table storing a used/unused state of a plurality of corresponding first CONNECTOR identifiers, each first CONNECTOR identifier defining a group including two or more first LEG identifiers,a first associated LEG table storing a plurality of first LEG identifiers each corresponding to a first CONNECTOR identifier whose state is registered as being used in said first CONNECTOR management table, andfirst control means for updating said first CONNECTOR management table and said first associated LEG table according to an indication received from a service control device, and for establishing a call according to said first associated LEG table; and
the service control device includinga second CONNECTOR management table storing a used/unused state of a plurality of corresponding second CONNECTOR identifiers,a second associated LEG table storing second LEG identifiers each corresponding to a corresponding second CONNECTOR identifier whose state is registered as being used in said second CONNECTOR management table, the second LEG identifiers being stored corresponding with the corresponding second CONNECTOR identifier, andsecond control means for determining a second LEG identifier and a second CONNECTOR identifier to be used according to a destination and a service of a call designated by a subscriber accommodated in the corresponding service switching device, for setting a determined result in said second CONNECTOR management table and second associated LEG table, and for transmitting an instruction to accord said first CONNECTOR management table and first associated LEG table with said second CONNECTOR management table and second associated LEG table to the service switching device.

Abstract
A call control processing system in an intelligent network providing a service to a subscriber terminal of a user when the user requests a service such as a conference call. The call control processing system has an internal primitive unit for managing the physical requirements of the subscriber terminal in response to a number allocated to the call and requests a concept generating and managing unit to execute the service request processing. The concept generating and managing unit generates and manages a concept independent of the physical condition, such as a concept expressing a path between the service switching point and the service control point and a concept for connecting more than two paths and transmitting a message based on the concept through a telephone signal network to the service control point.

5. A service switching device as one of a plurality of service switching devices provided in an intelligent network including a service control device and the plurality of service switching devices, said service switching device comprising:
-
converting means for converting between a call number and a LEG identifier, wherein the call number identifies an outgoing call from a first subscriber accommodated in the corresponding service switching device to a second subscriber or the call number identifies an incoming call to the first subscriber, accommodated in the corresponding service switching device from the second subscriber, and wherein the LEG identifier is commonly recognizable by the plurality of service switching devices, a first CONNECTOR management table storing a used/unused state of a plurality of corresponding first CONNECTOR identifiers, each first CONNECTOR identifier defining a group including two or more first LEG identifiers, a first associated LEG table storing a plurality of first LEG identifiers each corresponding to a first CONNECTOR identifier whose state is registered as being used in said first CONNECTOR management table, and first control means for updating said first CONNECTOR management table and said first associated LEG table according to an indication received from a service control device, and for establishing a call according to said first associated LEG table; and
wherein the service control device includesa second CONNECTOR management table storing a used/unused state of a plurality of corresponding second CONNECTOR identifiers, a second associated LEG table storing second LEG identifier each corresponding to a corresponding second CONNECTOR identifier whose state is registered as being used in said second CONNECTOR management table, the second LEG identifiers being stored corresponding with the corresponding second CONNECTOR identifier, and second control means for determining a second LEG identifier and a second CONNECTOR identifier to be used according to a destination and a service of a call designated by a subscriber accommodated in the corresponding service switching device, for setting a determined result in said second CONNECTOR management table and second associated LEG table, and for transmitting an instruction to accord said first CONNECTOR management table and first associated LEG table with said second CONNECTOR management table and second associated LEG table to the service switching devices.
