ishmael,
don’t do that !! it’s a bad choice. Keep the same LAC over the whole village.
If you go on with your idea:
– lot of location updates –> you need to add more SDCCH timeslots on all BTS (1 -> 6)
– inter BSC HO are slower and usually are restrictive (not all causes available ? it’s vendor dependent)
– risk of some pagings repetitions over the whole MSC (if one MS is chaging LAC often, it might miss a paging, and the MSC might repeat it in all cells of MSC)
