Abstract: An access device receives content from a broadband IP network to be communicated to a wireless handset over a radio access network (RAN). The access device acquires a user profile utilized in the radio network for the wireless handset. Based on the acquired user profile, the access device determines transmission parameters utilized for communicating the received content to the wireless handset using an air interface protocol over the radio access network. A security level and/or a security protocol, a transcoding mechanism, and/or transmission bit rate are determined based on the acquired user profile. A resolution, transmission bit rate, coding structure, security protocol and/or security level for transmitting the received content to the wireless handset are adjusted based on the acquired user profile. Alternately, the access device is enabled to receive content from the wireless handset using a transmission profile determined Lased on user profile of the wireless handset.

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: A multi-standard GNSS receiver, handle different global navigation satellite systems (GNSSs), determines with respect to a current time instant, the earliest broadcast timing based on corresponding satellite broadcast cycles for satellites in the different GNSSs. The multi-standard GNSS receiver acquires broadcast ephemeris at the determined earliest broadcast timing to determine its own first position. A search order is determined based on the corresponding satellite broadcast cycles and the current time instant. The multi-standard GNSS receiver may selectively utilize appropriate satellite receivers such as the GPS receiver and the GLONASS receiver to search for satellite signals based on the determined search order. Channels for different GNSSs are scanned to identify transmitting satellites based on the corresponding satellite broadcast cycles for ephemeris downloading. The satellite search is prioritized by comparing the current time instant with the corresponding satellite broadcast cycles.

Abstract: A transmitting communication device may iteratively adjust its transmit power, and may estimate, based on iterative transmit power adjustment, relative location of a receiving communication device. The transmit power may be initialized to a maximum value, and the transmit power may be iteratively reduced until connectivity with the receiving communication device is lost. The loss of connectivity may be determined based on reception of responses to ping messages transmitted by the transmitting communication device. The transmitting communication device may authenticate the receiving communication device and/or a user of the receiving communication device. The authentication may comprises utilizing transmit power adjustment and/or relative location estimation therefrom to ensure that a separation between the devices does not exceed a maximum value. The transmitting communication device may generate location info associated with the receiving communication device based on the relative location estimation, and may communicate the location info to a location server.

Abstract: A combined GPS and GLONASS receiver receives GPS signals and GLONASS signals. A calibration signal is generated utilizing the received GPS signals and/or the received GLONASS signals to offset group delay errors in the received GLONASS signals. The generated calibration signal is filtered through Kalman filters to estimate group delay variations in the received GLONASS signals. The estimated group error delay variations are combined with the received GLONASS signals to calibrate the received GLONASS signals by offsetting the estimated group error delay variations. When GPS signals are not available for use, the combined GPS and GLONASS receiver obtains group delay errors stored or in the received GLONASS signals to estimate calibration coefficients. The estimate calibration coefficients are updated utilizing received GPS and/or GLONASS signals. The updated estimated calibration coefficients are stored before turning off the combined GPS and GLONASS receiver to expedite calibrating of GLONASS signals received upon turning on.
