Abstract: Exemplary embodiments include a method for managing user authentication credentials in relation to different types of core networks, CNs. The exemplary methods can include receiving (1010) a request to authenticate a user for access via a first CN, and determining (1020) that user authentication credentials are unavailable in relation to the first CN. The exemplary methods can also include sending (1030), to a translator function associated with a second CN that is different than the first CN, a request to provide user authentication credentials associated with the first CN. The exemplary methods can also include receiving (1040) user authentication credentials associated with the first CN and, based on the received user authentication credentials, authenticating (1050) the user for access via the first CN. Embodiments also include data management nodes configured to perform the exemplary methods, as well as complementary methods and nodes configured to perform such methods.

Abstract: Described is a system for characterizing communication devices by device type. The system obtains device information for a variety of communication device types, each device type associated with a user account of a bidirectional network. The communication device types are analyzed to perform regional and temporal device characterization, behavioral and feature device characterization, and device homophily analysis on the bidirectional network. The analysis is then used for targeted regional marketing.
