US Classification:

370350, 370338, 370466

Abstract:

Aspects of a method and system for preserving content timing across femtocell interfaces via timestamp insertion are provided. In this regard, a femtocell may receive a first time-stamped packet via a first interface and transcode the time-stamped packet. The femtocell may buffer the transcoded packet based on a time-stamp recovered from the packet and may transmit the buffered transcoded packet via a second interface. One of the first interface and the second interface may utilize the Internet Protocol. One of the first interface and the second interface may be a non-cellular interface and the other interface may be a cellular interface. The femtocell may be operable to generate a timestamp corresponding to a time instant at which a time-stamped packet arrived via the first interface or the second interface. The timestamp may be referenced to a clock within a cellular enabled communication devices communicatively coupled to the femtocell.

Abstract:

Aspects of a method and system for timely delivery of multimedia content via a femtocell are provided. In this regard, a femtocell may receive data via an upstream path and transmit data via a downstream path. One of the upstream path and downstream path may comprise a cellular path and the other may comprise a non-cellular path. One or both of the upstream path and the downstream path may be audio video bridging (AVB) paths. Data may be stored in the femtocell based on timing characteristics of one or both of the upstream path and the downstream path. Data may be delivered to the femtocell utilizing best effort delivery and the data may be forwarded by the femtocell with guaranteed quality of service. Resources in the femtocell may be reserved and/or synchronized, utilizing AVB protocols, for communication of one or more data streams.

Abstract:

Aspects of a method and system for communication are provided. In this regard, a femtocell may receive messages from a plurality of different sources comprising one or more other femtocells, one or more cellular enabled communication devices, and one or more non-cellular network nodes. The femtocell may select, based on the received messages, a master clock within one of the plurality of different sources as a master clock for synchronization of the plurality of different sources. A femtocell clock, a global navigational satellite signal (GNSS) clock, a cellular base station clock, or a cellular enabled communication device clock may be selected as the master clock. The femtocell may transmit and/or receive synchronization messages to and/or from the one or more cellular enabled communication devices and the one or more non-cellular network nodes.
