This post explains how mobile phones discreetly transmit their GPS location to carriers using protocols such as RRLP (Radio Resource LCS Protocol) and LPP (LTE Positioning Protocol). These mechanisms, operating within the control plane of cellular networks, enable carriers to pinpoint a device's location without user intervention. The process relies on automated exchanges between the device and the network to provide geolocation data.
