Cellphones are always looking for "Where's the closest cell tower" and to the providers, they refer to this as a PING.
If at least two towers receive this PING from the same phone, then navigational triangulation becomes possible.
 
BTW: Sonar and Radar operate on the 'reflected wave' principle and the reflection itself is often referred to as a Ping.
