1. A method of operating a wireless communication network to attest to a geographic location of a wireless user device, the method comprising:
a network access node receiving signaling transferred by the wireless user device that indicates the wireless user device, the geographic location, satellite signal characteristics for satellite signals received by the wireless user device at the geographic location, and terrestrial signal characteristics for wireless signals received by the wireless user device at the geographic location;
the network access node transferring the signaling for delivery to a location attestation node;
the location attestation node receiving the signaling transferred by the network access node, determining known signal characteristics for the geographic location, comparing the known signal characteristics to the satellite signal characteristics and the terrestrial signal characteristics, and generating a location-attestation score based on the comparison;
the location attestation node encrypting information that indicates the wireless user device, the geographic location, and the location-attestation score; and
the location attestation node transferring the encrypted information for delivery to an information consumer that has a decryption key for the encrypted information.
