Abstract:
Methods and apparatuses bind a user's IMS public identity to, and unbind it from, a mobile device (MD) shared among multiple users. In binding the user's IMS public identity, a message is received from the MD, which message comprises a shared service authorization access token that is associated with a shared service and that comprises an identifier of a user of the MD. The message further comprises a default public identity of the MD. Based on the user identifier and the default public identity, the user is determined to be authorized to use the MD for the shared service. In response to the determination, a public identity of the user is obtained and mapped to the MD to bind a private identity and a public identity of the MD and the public identity of the user, and a user subscription database is instructed to update the user's service subscription information.
Abstract:
A method and apparatus for bootstrapping secure connections between wireless devices and deployable wireless communications networks. Using the method, a wireless device establishes a connection to an auxiliary network, and then establishes a connection with a deployable subscription bootstrapping service. The deployable subscription bootstrapping service generates a temporary subscription profile, including a temporary shared symmetric key, for the wireless device, writes the temporary profile to a deployable home subscriber server, and communicates the temporary profile to the wireless device, which stores the temporary profile. The wireless device then terminates the connection to the auxiliary network, and initiates a connection with the deployable wireless communications network using the temporary subscription profile.
Abstract:
A system for, and method of, single sign-on collaboration among a plurality of mobile devices, includes a server for issuing a first identity token to subsequently authenticate a user of a first of the mobile devices to a service provider, and for generating and sending a collaboration credential to the first device based on the first identity token or user authentication. The first device sends the collaboration credential generated by the server to a second device paired with the first device. The server also issues a second identity token to subsequently authenticate to the service provider the user of the second device based on the collaboration credential received from the first device, to support single sign-on collaboration for the user across the plurality of mobile devices.
