Method for roaming in mobile radio network using additional Remote Home Location Register which is integrated into calling subscriber network

摘要

Calls are connected through to a subscriber or from a subscriber who stays in a mobile radio network different to the network stated in the contract. The connection does not have to be routed over the subscriber's contract network. An additional Remote Home Location Register is integrated into the network in which the calling subscriber stays. The RHLR includes data of subscribers who are logged into mobile radio networks which can be reached from the network of the calling subscriber and connected via roaming agreement.
