Abstract: Aspects of a method and system for service mobility via a femtocell infrastructure are provided. In this regard, a mobile cellular enabled communication device may detect a femtocell operable to deliver content for one or more services to the mobile cellular enabled communication device, where the one or more services may be provided via a set-top-box communicatively coupled to the femtocell. The mobile cellular enabled communication device may communicate a user profile to the femtocell, wherein information in the profile may be utilized by the set-top-box to authenticate and/or authorize access to the services by the mobile cellular enabled communication device and thus the mobile cellular enabled communication device may receive the content from the set-top-box based on the authentication and/or authorization. The content may comprise voice, video, data, text and/or still images. The mobile cellular enabled communication device may detect the femtocell by receiving one or broadcast messages from the femtocell.

Abstract: Aspects of a method and system for controlling access and utilization of femtocells via a network based service are provided. In this regard, a femtocell management entity communicatively coupled to a network and operable to manage one or more femtocells may be accessed via an end-user communication device. In this manner, the femtocell(s) may be managed via the end-user device such as one of the cellular enabled communication devices. The femtocell management entity may enable establishing one or more SLAs between the femtocell(s) and the cellular enabled communication device(s). The SLA(s) may enable the cellular enabled communication device(s) to establish one or more cellular communication channels with the femtocell(s). The SLA(s) may determine when the cellular communication channels may be established. The SLA(s) may determine how a femtocell owner/operator may be compensated for providing cellular service. The femtocell(s) may be accessed utilizing Internet Protocol.

Abstract: Upstream frequency response measurement and characterization. Signaling is provided between respective communication devices within a communication system. Based upon at least one of these signals, one of the communication devices captures a number of sample sets corresponding thereto at different respective frequencies (e.g., a different respective center frequencies, frequency bands, etc.). Then, spectral analysis is performed with respect to each of the sample sets to generate a respective and corresponding channel response estimate there from. After this number of channel response estimates is determined, they are combined or splice together to generate a full channel response estimate. In implementations including an equalizer, different respective sample sets may correspond to those that have undergone equalization processing and those that have not.

Abstract: Methods, systems and computer program products to synchronize timing of data transmissions between wireless and wired networks using a combined wireless gateway and cable modem are provided herein. The method includes the step of generating an indicator prior to a look-ahead time period and transmitting a poll to a wireless device upon sending the indicator. The look-ahead time period is a time period from transmitting the indicator to transmitting the DOCSIS frame. The method further includes the step of receiving data from the wireless device and encapsulating the data in a DOCSIS format to generate a DOCSIS frame. The method also includes transmitting the DOCSIS frame at a start of a next transmit opportunity to a cable modem termination system (CMTS).

Abstract: Aspects of a method and system for mitigating interference among femtocells via intelligent channel selection are provided. In this regard, signals which may interfere with cellular communications between a femtocell and a cellular communication device may be detected via the femtocell. Based on the detection, the femtocell may be configured to transmit and/or receive signals on one or more frequencies and/or channels. The one or more frequencies and/or channels may be determined in the femtocell and/or in a network management entity. Detecting interfering signals and configuring the one or more femtocells may occur periodically, upon installation of a femtocell, upon power-up of a femtocell, and/or upon command from a network administrator. The results of the detection may be communicated to one or more other femtocells and/or to a network management entity.
