Abstract
A method for initiating a roaming communication link with a user equipment in a visited communication network comprises: transmitting a registration request by the UE to a network entity of the visited communication network; detecting by the network entity of the visited communication network that the registration request is related to a roaming communication with the UE; determining by the network entity of the visited communication network a home communication network of the UE; retrieving, by the network entity of the visited communication network, subscriber-specific data of the UE from a routing data layer entity of the visited communication network for roaming the UE in the visited communication network, wherein the RDL entity is coupled to the home communication network of the UE via a data base interface; and initiating the roaming communication link with the UE based on the subscriber-specific data of the UE received via the RDL entity.
