The purpose is to track the location of a specific phone using triangulation based on the closes cell towers which receive the phone’s signals. The phone maintains a connection to the nearest cell tower(s) to be on the network in case a call is initiated.
It’s not necessarily intended to intercept, although I believe there were some that downgraded G3 to G2 to be able to potentially do that.
I don’t know whether downgrade attacks are still viable (or needed).

As far as I understand, outside of active interception the only use for these things is warrantless dragnet surveillance of location. (And active interception is increasingly not possible due to better security practices.)
