1. 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
   在移動通信的位置更新過程中，傳統(tǒng)的靜態(tài)位置區(qū)方案存在著缺乏變化的靈活性、邊界振蕩、信令負載過于集中問題，本文提出了一種新的自適應位置更新方案，采用不同級別的位置區(qū)，位置區(qū)的選擇根據(jù)移動臺當時的移動和呼叫情況，按照使位置更新和尋呼的無線信令總代價最小的原則確定.該方案可有效地解決靜態(tài)位置區(qū)的各種問題，并能方便地與其它位置區(qū)方案切換
