SYSTEM AND APPARATUS FOR POWER EFFICIENT DELIVERY OF SOCIAL NETWORK UPDATES TO A RECEIVER DEVICE IN A BROADCAST NETWORK

摘要

Systems and methods for delivering social network updates from popular entities to broadcast or multicast networks to receiver devices obtain updates from very popular entities. Updates may be accomplished by a server that crawls social network sites. To enable selective reception, the obtained updates may be broadcast / multicast, depending on the schedule previously communicated to the receiver devices, such as the catalog file. The receiver devices receive the catalog file and, using the information contained therein, selectively receive updates associated with the user of the receiver device. Updates received from broadcasts or multicasts are cached in the memory of the receiver device. When a user requests access to a particular social network entity on the receiver device, the request may be satisfied by accessing cached social network updates on the receiver device. Broadcasting and / or multicasting very popular social network updates may mitigate the burden on unicast networks.
