<p>The present invention provides a‘411xx’value added service to wireless users. The disclosed‘411xx’service allows a mobile user who may be unfamiliar with their current geographic location to nevertheless obtain quick, accurate, and current information relating to the geographic area, e.g., different services in their current location, stores, libraries, gas stations, etc., via a mobile terminated (MT) short message system (SMS) message. In addition to the traditional‘4-1-1’dialed digits, a mobile user would also dial a number (or numbers) representing a feature code for a particular service, e.g., nearby ATMs, or traffic information. Upon receiving a 411xx call, the MSC generates an ORREQ/TCAP trigger based on a translation of the requested service represented by the extra‘xx’digits. The 411xx call is terminated on the MSC after an audible whisper notice plays to the caller, e.g.,“thank you for calling, your requested information will be sent momentarily”.</p> |
