Improved Location Management for Reducing Traffic Cost in 3G Mobile Networks

摘要

For reducing the load of Home Location Register (HLR) in 3G mobile networks, we propose a mobility scheme to efficiently provide Intelligent Networks Service (INS). Once INS service profile is downloaded from Service Control Point (SCP) into Visitor Location Register (VLR), the INS is managed by only VLR not to connect SCP, so the service management cost is hardly affected by the call arrival rate as INS profile is provided by VLR where Mobile Host (MH) locates, not SCP. The proposed scheme is better performance than previous methods in 3G mobile networks.
