Overflow control in mobile communication using N -class replacement
Kuen-Liang Sue, Chi-Chun Lo · Electronics Letters · 2003
A strategy called N-class replacement (NR) policy is proposed to overcome visitor location register (VLR) overflow in a mobile communication system. The NR policy requires only few bits in the VLR record. It is feasible for separated VLR databases in real mobile networks. For the rate of excellent replacement, the simulation results show that the NR policy outperforms currently proposed policies.
