摘要： A distributed radio system is disclosed. Transmit and receive packets of data are transported over a relatively high-speed multiplexed network, which in one embodiment may be an Ethernet network. The distributed radio system comprises in one embodiment a centrally-located network-level processing unit connected via network connections to one or more intermediate-level processing units. The intermediate-level processing units may be distributed throughout the coverage area. The processing units perform digital signal processing, as well as higher level processing such as signal routing, speech transcoding and proper interfacing to external environments, such as a macrocellular environment. Radio elements are provided that are accurately timed or synchronized, such that the radio elements have their own time base to ensure proper transmission, even when unpredictable network delays occur.

摘要： Crystal oscillator control and calibration is disclosed. Temperature and frequency control circuits included on a printed circuit board (PCB) comprising a crystal oscillator are used to determine, for each of a plurality of set points in a range of sensed internal temperatures sensed by an internal temperature sensing circuit or device located adjacent to the oscillator in a thermally insulated region of the PCB, a corresponding compensation required to be applied to maintain a desired oscillator output frequency. The PCB is configured to use at least the determined compensation values and a sensed internal temperature to determine during operation of the PCB a compensation, if any, to be applied to maintain the desired oscillator output frequency.

摘要： Providing mobile network security is disclosed. A first mobile network provider equipment registers using a secret data that is known to a registration entity with which the first mobile network provider equipment is configured to register and embodied in a physical device associated with the first mobile network provider equipment in a manner that enables the physical device to be used to perform a cryptographic function using the secret data but prevents the physical device from being used to provide the secret data as output. An encryption data usable to communicate securely with a second mobile network provider equipment over a packet data network is received from the registration entity.

摘要： A phase locked loop with phase clipping and/or resynchronization is disclosed. A reference signal is compared to a feedback signal derived at least in part from an output signal of an oscillator to determine a phase error. A magnitude of at least one of the phase error and a change in the phase error, if required, is clipped to provide at least one of a clipped phase error that has a clipped magnitude that does not exceed a prescribed maximum phase error and a clipped change in phase error that has a clipped magnitude that does not exceed a prescribed maximum change in phase error. If a resynchronization triggering event is detected, the oscillator is resynchronized with the reference signal.
