copy/paste from one of the 3g books:
--------------------------------------
Service Area (SA)
The SA identifies an area of one or more cells of the same LA (Location Area). And is used to indicate the location of a UE (User Equipment) to the CN (Core Network).The combination of SAC (Service Area Code), PLMN -Id (Public Land Mobile Network Identifier) and LAC (LocationArea Code) is the Service Area Identifier.
SAI = PLMN-Id + LAC + SAC
---------------------------------------
I would like to clarify what is direct/main purpose of CN to know where the UE is located?
Is it only for government to track your way? :)
or is it mainly for location based services ? (like example: .. you are traveling via highway, suddenly you get (free) sms message "Hi, you are approaching Las Vegas city .. please find SuperDuper hotel on your right side, check-in in next 30 minutes and you get 30% discount and lunch for free.." )
any other idea?
