Abstract

Systems and methods which provide data communication content delivery through, a hybrid network implementation are disclosed. A hybrid network configuration may utilize a broadcast communication technique to deliver large amounts of data communication content to one or more mobile communication device via uni-directional network links and a uni-cast communication technique via bi-directional network links with the one or more mobile communication device to facilitate delivery and utilization of the data communication content. Data content delivery loss recovery techniques implemented according to embodiments of the invention utilize network links of the hybrid network other than or in addition to the uni-directional network links to implement loss recovery techniques such as a hybrid repeat technique, a hybrid retransmission technique, hybrid statistical feedback technique, and/or combinations thereof.

Claims20

Dependent claims

A method comprising:

establishing a bi-directional network link with a host of data communication content;
establishing a uni-directional network link with the host;
receiving data communication content from the host at least in part through the uni-directional network link, wherein the data communication content is received as one or more data packets;
determining lost packet information associated with the one or more data packets from a plurality of user devices;
transmitting the lost packet information from each of the plurality of user devices to the host via the bi-directional network link, wherein the host implements a data content delivery loss recovery technique based on the lost packet information, wherein the data content delivery loss recovery technique includes
aggregating lost data packets identified based on the lost packet information transmitted to the host via the bi-directional network link, wherein the host transmits the aggregated lost data packets in response to a determination that a size of the aggregated lost data packets satisfies a threshold corresponding to a frame size, wherein said aggregated lost data packets are transmitted to each of the plurality of user devices, whether said lost data packets are associated with a same or different user device of the plurality of user devices.

A system comprising:

a communication device hosting transmission of data communication content, the communication device including:
an intelligent multiplexing module adapted to coordinate communication, associated with transmission of the data communication content, through both a bi-directional network link and a uni-directional network link;
logic adapted to implement at least one data content delivery loss recovery technique with respect to the data communication content transmitted through the uni-directional network link in response to receiving feedback from one or more of the plurality of user devices via respective bi-directional communication links, wherein particular feedback received from a particular user device of the plurality of user devices identifies one or more data packets associated with the data communication content that are regarded as lost by the particular user device, wherein the at least one data content delivery loss recovery technique includes:
aggregating lost data packets identified based on the feedback;
and
transmitting the aggregated lost data packets in response to a determination that a size of the aggregated lost data packets satisfies a threshold corresponding to a frame size, wherein said aggregated lost data packets are transmitted to each of the plurality of user devices, whether said lost data packets are associated with a same or different user device of the plurality of user devices.
