A Modified Profile-Based Location Caching With Fixed Local Anchor for Wireless Mobile Networks

Profile-Based Location Caching with Fixed Local Anchor (PCFLA) Strategy can reduce the frequent access to the HLR. As a result, the total management cost is minimized in a wireless mobile network. However, if the MT's information is not found at calling MSC then the HLR is accessed to get that information every time. Middle Location Register (MLR) is located between VLR and HLR. It helps to reduce the heavy load at HLR. Modified PCFLA (MPCFLA) combines the MLR with PCFLA to improve the performance of PCFLA. The analytical results show that the authors' proposed method reduces the overall cost than PCFLA strategy.
