ABSTRACT:
A manual home location register (M-HLR) for use in a cellular telecommunication system provides manual visitors in a visited network with the same registration capabilities as automatic visitors from networks that have automatic roaming agreements with the visited network. The M-HLR maintains a database of manual visitor information separate from the network's database of home subscribers and automatic visitors. Initial registration in the visited network by a manual visitor is recorded in the M-HLR and enables the manual visitor to roam freely between multiple mobile switching centers (MSCs) in the visited network without having to re-register in each MSC.
