Method and apparatus for binding of a user-based public identity to a shared device in an internet protocol multimedia subsystem (IMS)-based communication system

摘要

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.

主权项

1. A method for binding a user's Internet Protocol Multimedia Subsystem (IMS) public identity to a mobile device that is shared among a plurality of users, the method comprising:
receiving, by an infrastructure element from a mobile device, a message comprising a shared service authorization access token that is associated with a shared service, wherein the shared service authorization access token comprises an identifier of a user of the mobile device and wherein the message further comprises a default public identity of the mobile device; based on the identifier of the user and the default public identity of the mobile device, determining that the user is authorized to use the mobile device for the shared service; in response to determining that the user is authorized to use the mobile device for the shared service, obtaining a public identity of the user; mapping the public identity of the user to the mobile device to bind a private identity and a public identity of the mobile device and public identity of the user; instructing a user subscription database to update the user's service subscription information; and registering the mobile device with an IMS using the public identity of the mobile device and the public identity of the user.
