2. Contents  Common Tag Mobile System is…  Advantage of Common Tag Mobile System  Both Nodes interface  Packet Control Manager  Tag Mobile System Protocol  System Architecture 2

3. Channel Switching Tag Mobile System Monitoring Server Monitoring Client TAG Mobile Node Channel#1 Channel#2 Tag Parent Node TAG Mobile Node Local Channel 3 M M M M Mobile Node

4. Why use Local Channel? 4

5. Common Channel Tag Mobile System Monitoring Server Monitoring Client TAG Mobile Node PAN#1 Same Channel PAN#2 Tag Parent Node TAG Mobile Node PAN#Local 5

6. Advantage  Reduced Channel Switching Overhead  Don’t interfere Basic Work  Routing  Message delivery  Emergency call  Etc.  Protocol Simple  Implementation Simple 6
