System and method for service invocation and response with a communication device based on transmitted code content recognition

摘要

A system and method for enabling a user to invoke a service over a signaling channel in a communication system with a communication device such as a mobile phone. The user dials a series of digits into their phone and enters them into the disclosed system, for example by pressing the send key on a mobile phone. The digits entered by the user include a prefix or routing code, and a data code. The dialed digits are transferred to a call switching system, which determines, based on the prefix code, a processing system to which a message is sent. The processing system further determines, based on the data code of the dialed digits, the service to provide and how the service should be fulfilled. The service can be fulfilled by content over the signaling channel or a transport channel, or both.

主权项

1. A method for fulfilling a service requested via a communication device, the method comprising:
configuring at least one rule for service fulfillment of a data code; receiving, by a call-switching system from the communication device, a dialed digit string comprising a non-numeric prefix code and the data code in a call; suspending the call and recognizing, by the call-switching system, the prefix code in the dialed digit string, and in response, (i) translating the prefix code into a destination address of a service control point (SCP) and (ii) communicating, based on the destination address, a request message comprising the dialed digit string to the SCP which in turn forwards the request message to a service processing-system associated with the SCP; following receipt by the service-processing system of the request message, identifying the data code contained therein; looking up, by the service-processing system in a stored database, the at least one rule for service fulfillment based on the data code; and if the service processing system determines the data code is valid, providing service fulfillment, by the service-processing system, based on the at least one rule; otherwise, transmitting by the service processing system via the SCP to the call-switching system a command configured to cause the call-switching system to continue translate the prefix code and resume the call processing.
