Methods and apparatus for reducing data capture and storage requirements for call and transaction related message monitoring and fraud detection

A method comprising:

• detecting, at a first monitoring system in a first network portion, that a first telephone call-related signaling message originating from the first network portion is directed to a second network portion via an intermediate network, the first telephone call-related signaling message containing first telephone call-related signaling information;
• storing at least a portion of said first telephone call-related signaling information in a data store associated with the first monitoring system;
• sending a notification message from the first monitoring system to a second monitoring system in said second network portion using said intermediate network, said notification message indicating that the first telephone call-related signaling message is being communicated to said second network portion;
• sending said first telephone call-related signaling message to said second network portion through said intermediate network;
• receiving said notification message at said second monitoring system;
• receiving at said second network portion from said intermediate network a second telephone call-related signaling message corresponding to the first telephone call-related signaling message, the second telephone call-related signaling message containing second telephone call-related signaling information;
• and
• in response to said received notification message, storing at least a portion of said second telephone call-related signaling information in a data store associated with the second monitoring system.

• sending a notification message from the first monitoring system to a second monitoring system in said second network portion using said intermediate network, said notification message indicating that the first signaling message is being communicated to said second network portion;
• sending said first signaling message to said second network portion through said intermediate network;
• receiving said notification message at said second monitoring system;
• receiving at said second network portion from said intermediate network a second signaling message corresponding to the first signaling message, the second signaling message containing second signaling information;
• and
• in response to said received notification message, storing at least a portion of said second signaling information in a data store associated with the second monitoring system.

A method, comprising:

• receiving, at a first monitoring system in a first network portion, an indication of a specific group of telephone calls for which monitoring is requested;
• detecting that a first telephone call-related signaling message originating from the first network portion is associated with the selected group of telephone calls and directed to a second network portion, the first telephone call-related signaling message containing first telephone call-related signaling information;
• storing at least a portion of said first telephone call-related signaling information in a data store associated with the first monitoring system;
• sending a notification message from the first monitoring system to a second monitoring system in said second network portion using an intermediate network, said notification message indicating that the first telephone call-related signaling message is being communicated to said second network portion;
• sending said first telephone call-related signaling message to said second network portion through said intermediate network;
• receiving said notification message at said second monitoring system;
• receiving at said second network portion from said intermediate network a second telephone call-related signaling message corresponding to the first telephone call-related signaling message, the second telephone call-related signaling message containing second telephone call-related signaling information;
• and
• in response to said received notification message, storing at least a portion of said second telephone call-related signaling information in a data store associated with the second monitoring system;
• wherein the selected group of telephone calls includes telephone calls directed to at least one telephone number associated with the second network portion.
