This standard describes signaling support for Operator Services when the application providing the services resides in the Next Generation Network (NGN). The scope of this standard includes: (1) SS7 to SIP interworking for a call originating into the PSTN and directed toward the Operator Services System (OSS) in the NGN and (2) SIP signaling for a call originating into the NGN and directed toward the Operator Services System (OSS) in the NGN.In addition, this standard describes the signaling for establishing a call/session from the OSS to a further destination, noting the similarities to normal call/session setup signaling. Interconnection is assumed to be between trusted domains; the information and parameters required for this service are only available either within a trust domain or between trusted domains. In addition, in the absence of trust, and depending on exactly which information is not trusted, basic call setup may not function as expected. See more
