20090086740 | Customer Premises Gateway providing User Devices with Access to Internet Protocol Multimedia Subsystem (IMS) Services and Non-IMS Services - A customer premises gateway includes a connection manager, a registration manager and data storage. The registration manager registers the user devices connected to the gateway at the customer premises and stores information for the registered user devices, including identities for the user devices, at the gateway. The connection manager is operable to provide Internet Protocol Multimedia Subsystem (IMS) services and non-IMS services via a broadband network to the user devices connected to the gateway. The connection manager is also operable to provide the IMS services and non-IMS services to the registered devices based on the information stored for the registered user devices. | 04-02-2009 |
20090132712 | METHOD AND SYSTEM FOR SESSION MOBILITY BETWEEN END USER COMMUNICATION DEVICES - A method and system for providing session mobility between end user communication devices, such as between session initiation protocol (SIP) devices and universal plug and play (UPnP) devices. The session mobility methods and systems make use of a session manager, which can be part of a bridge coupled between the communication devices involved in a communication session, that allows the session to be moved to another end user communication device. The session manager controls the transfer of communication sessions between the end user communication devices. The session manager also is configured to control and manage the addition of end user communication devices to existing sessions between communication devices. As part of this session mobility between communication devices, the session manager can create a virtual device within the bridge to represent an actual communication device that is communicating with a different communication device in a different domain within the communication session. | 05-21-2009 |

The method involves a remote access device transmitting a remote access request to a service control application in the IMS-based network, the service control application authorizing the remote access request based on a number of criteria, and forwarding the remote access request to the home network. The forwarded remote access request includes information that allows protected content requested by the remote access request to be transmitted from a home network device in the home network to the remote access device upon appropriate verification of the remote access device by the home network device using home network device DRM schemes. Remote access of the protected content can be allowed by relaxing proximity restriction requirements of the home network. | 06-03-2010 |
20120290570 | IMPACT-BASED ARRANGEMENT OF IMAGES ON AN ELECTRONIC DISPLAY - Disclosed are methods for arranging list elements (e.g., results returned by a user search) according to anticipated “impact.” Thumbnails of the top elements are displayed on a screen of the user's device, with the size of each thumbnail related to that result's anticipated impact. In some embodiments, the arrangement of these thumbnails on the display screen is also based on the anticipated impacts with larger thumbnails placed near the center of the screen and successively smaller thumbnails arranged farther away. Different embodiments may calculate the anticipated impacts differently. The impact can be related to the rank order as assigned by a search engine. Any information about the user's current situation can go into the calculation of the anticipated impact. When the user is searching for information, longer video results may be assigned a larger anticipated impact because they are more likely to contain the wanted information. | 11-15-2012 |
