The traditional static location area scheme used in the location updating procedure of mobile communications has many problems,such as lack of flexibility,MS oscillating between LA borders,focused signaling load on border cells,etc. In this paper we present a new adaptive location updating scheme,which can solve the above problems,and can change easily to other LA schemes. The scheme uses multi-level LAs,selected according to single MS′s mobility and call characteristics,to make the best tradeoff between wireless signaling cost of location updating and paging.
