TCAP Application Context Aliases

Overview

When sending TCAP messages, the Application Context (AC) in the dialogue portion indicates the intended service for the message. These values are a reference to an explicitly defined set of the TC-User Application Service Elements, related options, and any other necessary information for the interworking of two TC-Users during an instance of communication.

The N2SVCD platform allows for generated ACs to be arbitrarily defined or be specified as an alias value for well-known ACs.
