IDENTIFICATION OF USER HOME SYSTEM IN A DISTRIBUTED ENVIRONMENT

摘要

Described is a method of identifying a home network of a user, for example, a roaming user connecting using a Wi-Fi connection, for example, via a wireless router, based on a user identification received by a first device of the network visited by the user. If the authentication device of the visited network cannot determine the home network of the user based on the user identification, then it queries a core platform, which may be outside the first network. The core platform queries nodes associated with possible home networks and, based on the responses received from the nodes, determines the home network of the user. The user can then be authenticated using the home network information.

1. A non-transitory processor-readable medium comprising instructions configured to cause, when executed by a processor of a user identification service core node, identification of a home network of a user based on a user identification of the user received by a first module of a first network visited by the user, the instructions comprising:
user identification receiving instructions configured to receive the user identification from a querying user identification service node of the first network, the querying user identification service node being associated with the first module of the first network; node querying instructions configured to query at least two target user identification service nodes as to whether the user identification belongs to one of the at least two target user identification service nodes, each node of the at least two target user identification service nodes associated with a respective network of a plurality of networks, and to receive a response from each of the at least two target user identification service nodes; and reply providing instructions configured to determine the home network of the user based on the response received from each of the at least two target user identification service nodes, and to transmit to the querying user identification service node of the first network a reply indicating the home network determined.
