Method and system for automatically accessing and invoking switch-based services in an advanced intelligent network

For use in an Advanced Intelligent Network (AIN) equipped with O-Called-Party-Busy trigger and leg manipulation functionality and having at least one service node and a Service Control Point (SCP) in electrical communication with a plurality of central offices via Transaction Capability Application Part (TCAP) signaling protocol, said service node operative as a virtual Service Switching Point (SSP) for subscribers to existing switch-based services, a method for automatically accessing and invoking said switch-based services without going off-hook, comprising:

• monitoring said TCAP signaling to detect predetermined triggers and line conditions associated with selected switch-based services;
• generating a first electrical signal for receipt by said SCP corresponding to said detected predetermined triggers and line conditions;
• automatically suspending normal call processing upon receipt of said first electrical signal and transferring call handling to said service node;
• generating a second electrical signal prompting said subscriber to select said associated switch-based service;
• generating a subscriber initiated electrical signal in response to said second electrical signal and for receipt by said SCP corresponding to said subscriber's selection decision;
• analyzing said subscriber initiated electrical signal;
• and
• automatically invoking said switch-based service selected by said subscriber.

For use in an Advanced Intelligent Network (AIN) equipped with O-Called-Party-Busy trigger and leg manipulation functionality and having at least one service node in electrical communication with a plurality of central offices via Transaction Capability Application Part (TCAP) signaling protocol, said service node operative as a virtual Service Switching Point (SSP) for subscribers to existing switch-based services, a method for automatically accessing Custom Local Access Signaling Services (CLASS) Automatic Callback (AC), without going off-hook so as to effect communication between participating stations, comprising:

• monitoring said TCAP signaling to detect said O-Called-Party-Busy trigger and predetermined line conditions necessary to invoke said CLASS AC feature;
• generating a first electrical signal for receipt by said SCP corresponding to said detected trigger and line conditions;
• automatically suspending normal call processing upon receipt of said first electrical signal and transferring call handling to said service node;
• obtaining the Directory Number (DN) associated with the most recent outgoing call by said subscriber;
• generating a second electrical signal prompting said subscriber to select said CLASS AC feature;
• and
• automatically invoking said CLASS AC feature if selected such that call completion may be attempted when said participating stations are idle.

For use in an Advanced Intelligent Network (AIN) equipped with O-Called-Party-Busy trigger and leg manipulation functionality and having at least one service node in electrical communication with a plurality of central offices via Transaction Capability Application Part (TCAP) signaling protocol, said service node operative as a virtual Service Switching Point (SSP) for subscribers to existing switch-based services, a method for automatically accessing Custom Local Access Signaling Services (CLASS) Automatic Recall (AR), without going off-hook so as to effect communication between participating stations, comprising:

• monitoring said TCAP signaling to detect said O-Called-Party-Busy trigger and predetermined line conditions necessary to invoke said CLASS AC feature;
• generating a first electrical signal for receipt by said SCP corresponding to said detected trigger and line conditions;
• automatically suspending normal call processing upon receipt of said first electrical signal and transferring call handling to said service node;
• obtaining the Directory Number (DN) associated with the most recent incoming call to said subscriber;
• prompting said subscriber to select said CLASS AR feature;
• and
• automatically invoking said CLASS AR feature if selected such that call completion may be attempted when said participating stations are idle.

For use in an Advanced Intelligent Network (AIN) equipped with O-Called-Party-Busy trigger and leg manipulation functionality and having at least one switch and a Service Control Point (SCP) in electrical communication with a plurality of central offices via Transaction Capability Application Part (TCAP) signaling protocol, said switch operative as a virtual Service Switching Point (SSP) for subscribers to Custom Local Access Signaling Services (CLASS), including Automatic Recall and Automatic Callback Services, a method for automatically accessing and invoking said Automatic Recall or Automatic Callback Services without going off-hook, comprising:

• monitoring said TCAP signaling to detect predetermined triggers and line conditions associated with invoking said Automatic Recall and Automatic Callback Services;
• generating a first electrical signal for receipt by said SCP corresponding to said detected predetermined triggers and line conditions;
• automatically suspending normal call processing upon receipt of said first electrical signal and transferring call handling to said switch;
• generating a second electrical signal prompting said subscriber to select said Automatic Recall or Automatic Callback Services;
• and
• automatically invoking said Automatic Recall or Automatic Callback Services if selected by said subscriber.
