To reduce the likelihood that test E911 calls will be improperly connected to a public safety access point (PSAP), while ensuring that mobile devices sold to consumers are correctly routed to a PSAP in an emergency, a system for automatically redirecting test E911 calls to an answering system is disclosed. An unstructured supplementary service data (USSD) node receives a first USSD message from a mobile device during E911 testing procedure at the mobile device. In response to identifying a first code in the first USSD message, the USSD node retrieves an identifier associated with the mobile device. The USSD node sends an instruction to a gateway mobile location center (GMLC) system to redirect E911 calls from the mobile device based on the retrieved identifier such that a subsequent E911 call placed by the mobile device is automatically rerouted by the GMLC to an answering line instead of a PSAP.
A system operating as an unstructured supplementary service data (USSD) node, the system comprising:
At least one computer-readable storage medium, excluding transitory signals and carrying instructions, which, when executed by at least one data processor of a system, cause the system to:
A gateway mobile location center (GMLC) system operating within a telecommunications network, the GMLC system comprising:
