Shopping centre uses mobile phone data to "monitor visitor levels"

The Mall should only have transient knowledge of the TIMSI, only so long as
it sees the base station & mobile device maintaining their registration.
(Every 10 minutes or so if I remember correctly.) Then the system can log
that visitor N appeared at time X, and spent Y minutes in the Mall.
The number of mobile phone visitors can then be used as a proxy for footfall
in the Mall, and the property company can justify the rent it charges. No
personal or identifying data is needed.
