1. A method comprising:
obtaining, by a processing system including a processor of a network device of a network, timing advance data regarding a communication device, wherein the timing advance data is obtained via control-plane signaling by the communication device in a network registration procedure;
processing, by the processing system, the timing advance data to determine a geolocation of the communication device;
storing, by the processing system, the geolocation at a storage device of the network; and
providing, by the processing system, the geolocation of the communication device to equipment of a network customer communicating on the network,
wherein the timing advance data is obtained and the geolocation is provided without requiring the communication device to engage in a user-plane session.
