Abstract
Abstract A method and system is provided for use in an Advanced Intelligent Network (AIN) for automatically accessing and invoking existing switch-based services without going off-hook. To be operative, the Advanced Intelligent Network must be equipped with O-called-party-busy trigger and leg manipulation functionality such as in AIN release 1.0 architecture and have at least one service node or suitable switch in electrical communication with a plurality of central offices via a suitable signaling protocol such as Transaction Capability Application Part (TCAP) protocol. The switch or service node must be operative as the home switch or virtual Service Switching Point (SSP) for subscribers to existing switch-based services. In operation, the signaling protocol is monitored to detect predetermined triggers and line conditions associated with selected switch-based services. Upon the detection of such predetermined triggers and line conditions, a first electrical signal corresponding thereto is generated for receipt by the service node SCP. Upon receipt, normal call processing is automatically suspended and call handling is transferred to the service node whereupon a second electrical signal is generated prompting the subscriber to select the associated switch-based service. If selected, by the entry of a Dual Tone MultiFrequency (DTMF) signal or other suitable response, the switch-based service will be automatically invoked without the user going off-hook.
