Patent number 8615648 is assigned to
The following quote was obtained by the news editors from the background information supplied by the inventors: "The invention relates to hardware and software based customer premise equipment (CPE) for use in interactive user sessions that involve multimedia. The invention further relates to an automated boot process, and to provisioning and activation technologies for these hardware and software clients.
"Session initiation protocol (SIP) is an existing request/response protocol for initiating, modifying, and terminating interactive user sessions that involve multimedia. SIP-based clients include both hardware and software based customer premise equipment (CPE). Generally, SIP provides signaling and session setup for Internet protocol (IP) communications involving multimedia.
"Traditional provisioning approaches used with SIP clients utilize a pull model for provisioning, in which the client checks for configuration changes periodically or requires to be rebooted to get configuration updates. As a result, updates to the SIP clients are traditionally not real-time updates. In addition, by design, SIP is a peer-to-peer protocol. As a result, traditional SIP applications are not configured to maintain persistence of data in a centralized place to enable the subscriber to have a consistent experience across a variety of platforms and hardware solutions. Also, the traditional back-office system does not support clients behind in-home NAT devices or nomadic clients.
"For the foregoing reasons, there is a need for a method and system for booting, provisioning, and activating hardware and software clients that address some of the shortcomings in existing approaches."
In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "It is an object of the invention to provide an improved method and system for booting, provisioning, and activating hardware and software clients.
"Some embodiments of the invention involve SIP clients; however, it is to be appreciated that various aspects of the invention may be used with other hardware and software clients used in interactive user sessions using other protocols.
"In one embodiment, the invention provides an automated method for booting up SIP-based clients, including both hardware and software based customer premise equipment (CPE). A top-down push mechanism is used for provisioning the user, service, and device information for a subscriber. Boot up configuration information is stored in the network, and supports stationary as well as nomadic SIP-based clients. In preferred embodiments, network address translation (NAT) traversal allows the booting up of SIP-based clients behind NAT devices.
"By using the top-down push mechanism, in some embodiments it may be possible to propagate updates from the billing system, provisioning system, self-care portal, etc., to SIP-based clients in real-time if the client is online. In the event that the client is not online, the updates could be provided at the next log in or boot up of the client.
"In some embodiments, configuration parameters (for example, user preferences, etc.) from the soft client or hard client may be uploaded to the provisioning system."
