Abstract
Aspects of the subject disclosure may include, for example, a network device that comprises a processing system including a processor and a memory storing instructions that, when executed by the processing system, facilitate performance of operations. The operations include obtaining timing advance data regarding a communication device served by the network; the timing advance data is collected by a network element coupled to the network device, and the network element communicates with the communication device using control-plane signaling. The timing advance data is processed using location data regarding the network element to determine a geolocation of the communication device. The geolocation is stored at a storage device; the network device and storage device are included in a secure portion of the network. The geolocation is provided to equipment of a network customer accessing the secure portion of the network via a secure interface. Other embodiments are disclosed.
