20080291930 | Handling Quality of Service in a Communication System - A method of ensuring an end-to-end Quality of Service for calls traversing an IP Multimedia Subsystem. The method comprises interposing a Home IP Multimedia Subsystem Gateway at the control plane between the IP Multimedia Subsystem and at least one non-SIP client. At the Home IP Multimedia Subsystem Gateway, SIP signalling is exchanged with a remote client on behalf of said non-SIP client, the Gateway performing a mapping between a media type identified within the SDP part of one or more SIP messages and a Quality of Service type specified for a protocol used to control the Quality of Service in the call leg between the non-SIP client and a Residential Gateway. The call leg is configured in accordance with the mapped Quality of Service type. | 11-27-2008 |
20090141735 | Multicast Control - A method and arrangement for optimizing bandwidth usage in a Multicast Services Control System (MSCS), which transports digital information in a multicast stream from a broadband network to a Set Top Box (STB) connected to a terminal TV. When the terminal TV is disabled, and can no longer utilize the multicast stream, the terminal TV sends a terminal status signal to the STB indicating deactivation of the terminal TV. In response, the STB sends an IGMP leave report signal to the broadband network, which then ceases its transmission of the multicast stream to the STB. | 06-04-2009 |

20100121985 | Large Scale Mobile Network Address Translation - A method and system for enabling a mobile station (MS) to transfer from one Network Address Translation (NAT) domain to another NAT domain. Dynamic rules created in the first NAT domain are transferred to the second NAT domain via a first Media Policy Routing function. A tunnel is created between the second NAT domain and the first MPR for transferring a MS session. A new session from the MS is created outside the tunnel and once the MS session times out, the MS session, the states existing in the first MPR and the second NAT domain utilizing a new set of dynamic NAT rules created in the second NAT domain are all removed. The tunnel is then removed and communication via a second MPR and the second NAT domain is available. | 05-13-2010 |

20100271981 | METHOD AND SYSTEM F0R DATA STREAMING - The present invention is a hybrid of a centralized solution and totally distributed peer-to-peer solution. It uses the load distribution idea of the peer-to-peer world. By splitting the multicast stream into a number of segments and transferring them through different trees, it overcomes the unbalanced resource usage faced by traditional single tree multicasting, thus improves the bandwidth efficiency of the network system and performance of the multicast application. In other words, it introduces the high resource efficiency of a peer-to-peer system into a network provider domain. | 10-28-2010 |

20100312861 | METHOD, NETWORK, AND NODE FOR DISTRIBUTING ELECTRONIC CONTENT IN A CONTENT DISTRIBUTION NETWORK - A method, network, and node for distributing content across a plurality of content cache nodes to provide optimal access to the content. Relevant, e.g. popular, content is distributed as close as possible to the user or group of users that have the highest probability of requesting the content. In addition, content is relocated to caching nodes higher in the aggregation network as content become less demanded, e.g. less popular. Portions of the content are distributed in a plurality of content cache nodes, and locations where particular portions of the content are requested by users with greater frequency than other locations are determined. The content portions are then migrated to content cache nodes closer to the locations where the particular portions of the content are requested by users with greater frequency. | 12-09-2010 |

20150085875 | ADAPTIVE VIDEO WHITE SPOT LEARNING AND USER BANDWIDTH DELIVERY CONTROL SYSTEM - A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage. | 03-26-2015 |
