Terminal Unique Number Assignment and Operation Method in Mobile Communication System

摘要

The present invention relates to an effective operating method of the ESN for the normal operation of the terminal and the system in a mobile communication system. In the present invention, the manufacturer code of the terminal unique number is reassigned to the terminal, and the reassignment type (RECYCLED_TYPE) is given to the terminal for multiple reassignments, and the SCM is newly set according to the given reassignment type, and according to the existing value. PLCM is created so that it does not collide with the long code mask. Therefore, even if the ESN is exhausted, it is possible to allocate additional ESNs without collision of the PLCM by the above method, thereby effectively solving the ESN exhaustion problem and the PLCM collision problem.;ESN, Terminal ID, PLCM, UIM_ID
