Abstract:
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; andthe 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.
