Time Advance refers to the round trip propagation delay between the antenna and the mobile terminal at the time the message was generated.

If signalling data are extracted from the Radio Access Network (RAN) they may contain some parameter values related to the radio channel between the antenna and the mobile terminal that are useful to narrow down the possible location of the latter.

It is linked to the (quantised value of the) physical distance between antenna and mobile device.
