| 20080244040 | Method and Apparatus for Dynamically Pushing Content Over Wireless Networks - The invention includes a method and apparatus for dynamically pushing content over a wireless network A method includes obtaining network-level state information and user-level state information for a user in response to an indication that content is available for the user, determining whether a network-level condition is satisfied using the network-level state information, determining whether a user-level condition is satisfied using the user-level state information, and pushing the available content toward the user terminal of the user using the wireless network in response to the conditions being satisfied. The network-level state information includes cell utilization information for a cellular region associated with the user terminal of the user. The user-level state information includes at least one of a user channel quality, a user terminal power state, a user terminal battery power status, a user terminal memory status, at least one user terminal capability, and user subscription information for the user. | 10-02-2008 |
| 20090089882 | Methods and Apparatus for Restricting End-User Access to Content - Methods and apparatus are provided for restricting end-user access to content Access of an end-user to content is restricted by receiving a request from the end-user to access the content; identifying and authorizing user associated with the end-user; providing an authorization message to the authorizing user, wherein the authorizing user is remote from a location of the end-user; and providing the end-user with access to the content if authorized by the authorizing user. For example, the end-user can be a child and the authorizing user can be an individual responsible for the child, such as a parent or guardian. In a further variation, the end-user can be an automated recording device and authorization request is responsive to an attempt by the recording device to record the content. | 04-02-2009 |
| 20090213775 | DETERMINISTIC FEEDBACK CONTROL FOR MULTICAST OR BROADCAST SERVICES - The invention relates to a method for controlling the transmission of feedback of mobile terminals receiving via an air interface of a mobile communication system a multicast or broadcast service transmitted or forwarded by a feedback control entity and to a mobile terminal, the feedback control entity using this method. Further, a communication system comprising a feedback control entity and a mobile terminal receiving a multicast or broadcast service is provided. To enable configurable and adaptive feedback for multicast or broadcast services provided via an air interface maintaining the end-to-end session concept the invention suggests that a feedback control entity deterministically selects a subset of the mobile terminals of the mobile communication system and which receive the multicast or broadcast service for providing feedback to the feedback control entity. In one embodiment of the invention the terminals are instructed to start or stop feedback provision by the feedback control entity by means of signaling. | 08-27-2009 |
| 20100057748 | Method and Apparatus for Parameterized Promotion and Delivery of Data - The invention includes a method and apparatus for promoting a data item within a data distribution network. In one embodiment, a method includes monitoring at least one parameter for the data item where the data item is associated with an application or service, propagating the data item from a first data server toward a second data server based on the monitoring of the at least one parameter for the data item, and propagating, toward at least one device, a message indicative of the propagation of the data item from the first data server toward the second data server. The message is for adapting the at least one device to identify the second data server as a source of the data item capable of serving future requests for the data item. | 03-04-2010 |
| 20100070700 | CACHE MANAGEMENT SYSTEM AND METHOD AND CONTENT DISTRIBUTION SYSTEM INCORPORATING THE SAME - A cache management system and method and a content distribution system. In one embodiment, the cache management system includes: (1) a content request receiver configured to receive content requests, (2) a popularity lifetime prediction modeler coupled to the content request receiver and configured to generate popularity lifetime prediction models for content that can be cached based on at least some of the content requests, (3) a database coupled to the popularity lifetime prediction modeler and configured to contain the popularity lifetime prediction models and (4) a popularity lifetime prediction model matcher coupled to the content request receiver and the database and configured to match at least one content request to the popularity lifetime prediction models and control a cache based thereon. | 03-18-2010 |
| 20100217869 | TOPOLOGY AWARE CACHE COOPERATION - A content distribution network (CDN) comprising a hierarchy of content storage nodes (CSNs) or caches having storage space that is allocated between local space for storing locally popular content objects and federated space for storing a portion of the less popular content objects. Local space and federated space based upon changes in content object popularity and/or other utility factors. Optionally, parent/child (upstream/downstream) communication paths are used to migrate content between CSNs or caches of the same or different hierarchical levels to avoid utilizing higher price top hierarchical level communications channels. | 08-26-2010 |
| 20100293294 | PEER-TO-PEER COMMUNICATION OPTIMIZATION - A peer-to-peer communication optimizer uses both peer locality and content diversity in a peer group to reduce network usage cost associated with using remote peers in a peer-to-peer system while reducing impact on the download time relative to peer-to-peer protocols operating with locality optimization alone or no localization of peers. The optimizer intercepts control messages in the peer-to-peer system and substitutes peer lists that meet both diversity indicator and network usage cost thresholds. Transparent embodiments operate without requirement to change peer or tracker implementations. Such embodiments include control message redirection, interception, and modification transparent to the client and tracker applications. Other embodiments include proxy designation. Still other embodiments include the use of gateway peers selected as function of diversity of content and network topology. Still other embodiments involve modification to one or more of client and/or tracker software and potentially the use of a standard interface for network topology determination. | 11-18-2010 |
| 20110078312 | Method and system for monitoring incoming connection requests in a Peer-to-Peer network - The present invention relates to a system and method for controlling peer-to-peer (P2P) traffic in an internet service provider (ISP) network. The system includes an ISP server configured to determine whether to accept or reject an incoming connection request to connect to a requested peer from a requesting peer in a P2P application. According to one embodiment, the ISP is configured to determine whether to accept or reject the incoming connection request based on current peer connectivity and cost of the incoming connection request. According to another embodiment, the ISP server determines whether to accept or reject the incoming connection request based on preference information available at the ISP server. | 03-31-2011 |
| 20110153802 | LOCALIZATION OF PEER TO PEER TRAFFIC - A method of processing peer-to-peer requests is provided. The method may include; storing, at a network element, peer information in a database for each peer of a plurality of peers, the peer information indicating at least one ISP associated with the peer and the content contained by the peer, receiving a request for content from a requester, and sending a response to the content requester based on the ISP with which the requester is associated and the stored peer information. | 06-23-2011 |
| 20110153835 | SYSTEM AND METHOD FOR CONTROLLING PEER-TO-PEER CONNECTIONS - The present invention relates to a system and method for controlling peer-to-peer connections in a Peer-to-Peer (P2P) streaming application for individual Internet Service Provider (ISP) networks over a localized overlay. The system may include a tracker local to a first ISP network configured to select edge peers among local peers of the first ISP network. The selected edge peers have external connections to peers outside the first ISP network in order to transfer sub-streams to or from the first ISP network, and the local peers not selected as edge peers have internal connections to other local peers within the first ISP network to transfer the sub-streams over the localized overlay. | 06-23-2011 |
