Abstract
Enhanced services are accessed from an enhanced services network element of a cellular radio telecommunications system using a cellular carrier specific code (#CCSC) string based office-level trigger and IS-41 messaging protocol message types. The invention takes advantage of the #CCSC standard to define MSC office-based trigger criteria wherein the dialed digits must start with the '#' character. When a call is received by the MSC in which the digits dialed start with '#' followed by a digit sequence, and an office-based trigger is provisioned for the '#' sequence dialed, the MSC suspends call processing and a service query message is generated and sent to the SCP of the requested enhanced service. The SCP then sends a response message back to the MSC, which resumes call processing in accordance with the response from the SCP.
