REALM BASED NETWORK-ACCESS-IDENTIFIER (NAI) MODIFICATION FOR A ROAMING PARTY NEEDING TO AUTHENTICATE WITH HOME NETWORK

摘要

A method and apparatus can be configured to find a service broker based on at least one identifier and communication with a home service provider via this service broker. The service broker acts as a proxy service provider for a service provider like the home service provider. The method can also include determining a realm associated to the at least one identifier. The method can also include creating a network-access-identifier based on the determined realm. The method can also include transmitting the network-access-identifier to the service broker for performing authentication of the user equipment in the home service provider.
