Abstract
The invention provides a method of roaming services for global roaming subscribers in the third generation mobile telecommunication networks in which a visitor network GLR(Gateway Location Register) is connected to a home network GLR so that the home network GLR can download subscriber information from HLR(Home network Location Register) to the visitor network GLR. In this manner, the visitor network GLR is blocked from direct contact to the home network HLR in the roaming service about the terminal moved to other network and downloaded with the subscriber information stored in the home network HLR in which the terminal is registered via the GLR so that the subscriber information stored in the home network HLR can be prevented from being exposed by the visitor network GLR. The visitor network GLR is associated with the home network GLR only in contrast to conventional association with all HLR of the home network so that a signal track can be remarkably reduced. Furthermore, the visitor network GLR can be downloaded with programs for various application or intelligent network services provided in the home network so that the terminal can be provided with the same services in the visitor network as in the home network.
