20110176543 | METHOD AND APPARATUS FOR REDUCING EFFECTS OF LOST PACKETS ON REDUNDANCY REDUCTION IN COMMUNICATION NETWORKS - A capability is provided for reducing the effects of lost packets on algorithms used for reducing or eliminating redundant traffic in cellular wireless networks. An encoding node encodes a target packet using a reference packet from a packet cache of the encoding node, and transmits the encoded packet to a decoding node having a packet cache. The decoding node receives the encoded packet and attempts to decode the encoded packet to recover the target packet. The decoding node detects that the reference packet identified in the encoded packet is missing from the packet cache of the decoding node. The decoding node generates a control packet identifying the missing reference packet and transmits the control packet to the encoding node. The encoding node receives the control packet and processes the reference packet stored in the packet cache of the encoding node in a manner for preventing use of the reference packet, by the encoding node, for encoding packets for transmission to the decoding node. | 07-21-2011 |

20120005276 | METHOD AND APPARATUS FOR REDUCING APPLICATION UPDATE TRAFFIC IN CELLULAR NETWORKS - An application proxy is disposed between a user device and an application server. The application server supports an application that is available on the user device. The user device registers with the application proxy for the application. The user device is prevented from transmitting application update request messages to the application server. The application proxy transmits application update request messages to the application server on behalf of the user device. The application proxy receives application update response messages from the application server. The application proxy determines, based on the application update response messages from the application server, whether to send an application update notification message toward the user device. In this manner, application update traffic normally transmitted via the network between the user device and the application proxy is reduced. The application update request and response messages may be polling messages, keep-alive messages, and the like. | 01-05-2012 |
