Abstract: Communication between virtual and physical management tools can be hindered as new features or data are added to virtual network management tools which are incompatible with older versions of traditional network management software. To maintain compatibility with older software, a virtual network manager stores version compatibility numbers for data within an entity inventory. The entity inventory indicates active entities in a virtual network. When another management tool communicates with the virtual network manager, the management tool can register with a software version number or include a version number in a data request. The virtual network manager uses the version number to retrieve compatible data from the entity inventory and generate compatible entity models. The entity models may include more or less data and be formatted differently based on the version number received.

Abstract: To effectively manage virtualized components, a virtual network manager aggregates components into entities and maintains an entity inventory that indicates available resources within a virtual network. However, aggregating components into entities and managing the entity inventory as components come on/offline can be computationally intensive. To reduce computation time and improve consistency, the virtual network manager uses a key service that associates components with entity keys. When a component is again instantiated within a virtual network, the virtual network manager passes an identifier for the component to the key service to retrieve an associated entity key. The virtual network manager then uses the entity key to quickly determine an entity that comprises the component and updates a record of the entity in the entity inventory with the component's data.

A message of the plurality of messages comprises a quantity and attributes of a set of network elements of the plurality of network elements having network element type that is the same, wherein the attributes of the set of network elements are from a technology-specific perspective.

Normalized versions of the plurality of network elements are created based on the type and the quantity defined by the set of declarations. The network simulation of the simulated network is executed and includes outputting the plurality of mock inventory messages that include attributes and status of the plurality of network element from a perspective of the at least one technology type.

Abstract: A geo-fence capable device is disclosed that is capable of performing an accurate geo-fence operation while minimizing power consumption. The device includes sensors, Wi-Fi connectability and GNSS. Sensors intermittently detect whether the device is in motion. When determined to be in motion, Wi-Fi is used to acquire a wireless access point list and to compare the access point list to previously-stored access points in order to determine whether the device is still within a particular region. GNSS is used to confirm exit from a region and to intermittently monitor whether the device has entered a new region. GNSS and application processor use can be minimized by utilizing sensor and Wi-Fi functionality as preliminary region monitors.

Abstract: A GNSS enabled device that is communicatively coupled to a network, receives time stamps via the network. The time stamps are generated based on reference clock signals within the network. GNSS receiver clock signal frequency may be adjusted based on the time stamps. When GNSS satellite signals and/or SRN signals are not available, the time stamps enable synchronization with GNSS satellites. Network clock signals and/or time stamps may be generated by an access point, a DSL modem, a cable modem and/or a primary reference clock within the network. A series of time stamps may be utilized for adjusting frequencies. Clock signals may be generated for adjusting frequencies based on a comparison between time stamps and oscillator or mixer output. Clock signals are generated for baseband, intermediate and/or RF frequency signal processing. GNSS satellite signals may be demodulated, correlated with a pseudonoise code sequence and/or synchronized based on the time stamps.

The RF characterization may indicate signal strength of signals received from RF sources detected and indentified by the communication device at the location.

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.

The narrowband GLONASS data streams and/or the narrowband GPS data stream may be processed at reduced sampling rates utilizing a shared sample memory in the integrated GNSS receiver. The narrowband GLONASS data streams and/or the narrowband GPS data stream may be stored in allocated sections of the shared sample memory. The stored narrowband GLONASS data streams and/or the stored narrowband GPS data stream may be processed using a correlation such as a fast Fourier transform (FFT) correlation.

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.

Abstract: A frequency synthesizer in a GNSS receiver chip enables duty cycling operation of the frequency synthesizer. The frequency synthesizer is cycled on to generate required clock signals for the GNSS receiver chip, and cycled off during a measurement duty cycle comprising measurement available intervals and measurement unavailable intervals. A reference clock inputted to the frequency synthesizer is on during the measurement duty-cycle. During the measurement available intervals, the frequency synthesizer is cycled on to generate the required clock based on the reference clock. During the measurement unavailable intervals, the frequency synthesizer is cycled off and clock timing is maintained based on the reference clock. A number of elapsed clock cycles of the reference clock is captured for a measurement unavailable interval and transferred to a clock offset. The GNSS receiver chip processes signals received using the required clock and the clock offset in a following measurement available interval.

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.
