    摘要: Aspects of a method and system for controlling data distribution via cellular communications with an integrated femtocell and set-top-box (IFSTB) device are provided. In this regard, a cellular enabled communication device may detect when it is within cellular communication range of a femtocell. Upon detection of the femtocell, the cellular enabled communication device may communicate instructions to a content source instructing the content source to deliver multimedia content to the femtocell. In instances that multimedia content is already being delivered to the cellular enabled communication device prior to the detection, the instructions from the cellular enabled communication device may instruct the content source to redirect the multimedia content to the femtocell. In this regard, the multimedia content may be delivered from the content source to the cellular enabled communication device via the femtocell. The femtocell may deliver at least a portion of the multimedia content to other communication devices.
