Abstract: A system and method for capturing and modifying roaming mobile subscriber information such as Serving MSCID, cell and sector location information, original dialed digits, subscriber profile and return address point code in support of service applications, such as wireless prepaid service for roaming subscribers. A network platform is inserted into the signaling path between a roaming subscriber's HLR and all Serving MSCs. The network platform intercepts messages exchanged between the roaming subscriber's Serving MSC and HLR, and extracts and stores information such as Serving MSCID, cell and sector data. The network platform may also modify the exchanged messages in support of service applications.

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.
