  • Patent number: 9907006
    Abstract: Systems and methods for adaptive access and handover configuration based on historical data are provided. Access and handover decisions are optimized in a multiple radio access technology environment using historical data associated with network performance. Future needs for access and handovers are predicted using historical data associated with the user and historical data associated with network performance. Performance metrics are received periodically or continuously from nodes in one or more networks at a centralized controller. The centralized multi RAT controller correlates these performance metrics and determines predicted handovers for a user device. Preparations for the predicted handovers can then be made prior to the handover event.

  • Patent number: 9763155
    Abstract: Systems and methods for staged connectivity and sleep mode are provided. Embodiments of the present disclosure optimize power consumption for a user across user devices by creating an ad hoc co-located network of user devices and establishing a device in the co-located network to act as a master (hub) device. In an embodiment, the system includes multiple user wireless devices and a network controller. The network controller identifies a set of proximate wireless devices and the power capability for each wireless device in the set. The network controller then selects a wireless device in the set to act as the hub (master) wireless device based on factors such as the power capabilities of each wireless device. The network controller then instructs the other wireless devices in the set to power down and instructs the appropriate network providers to handover communications to the hub (master) device.

  • Patent number: 9590688
    Abstract: Cellular processors are cascaded to provide different configurations, which result in higher-capacity base stations, increased numbers of simultaneous users over one frequency band, and/or aggregation of several carriers while still using only one radiofrequency (RF) chipset. The processors are aligned in both time and frequency, with each processor having a data port that allows data exchange with the other processors. The data alignment and exchange allow the processors, in the aggregate, to act as a single unit, resulting in a scalable architecture that can accommodate different system configurations.

  • Patent number: 9479978
    Abstract: Embodiments of this disclosure include methods in which a core network controller determines which femtocell base station to handover a cellular device to. Methods include comparing a cell parameter difference provided by a base station with a cell parameter difference provided by the cellular device. The cell parameter difference provided by the base station is the cell parameter difference between the base station and each neighboring base station. The cell parameter difference provided by the cellular device is the cell parameter difference between the base station through which the cellular device is currently associated with to the core network and each neighboring base station. The core network controller compares the cell parameter difference provided by the cellular device with the cell parameter difference provided by the base station. The core network hands the cellular device to the base station when the cell parameter difference provided by each are substantially equivalent.

  • Patent number: 9408100
    Abstract: Recent LTE communications schemes utilize such large amounts of data traffic, that there is little available bandwidth for performing sniffing of nearby base stations and/or cells, which is often integral in performing carious calibrations. Utilizing an LTE scheduler, small data traffic gaps can be detected in one or both of the receive chain and transmit chain. During these data traffic gaps, portions of sniffing data can be acquired and stored without significant interruption to the communication chains, where the overall process may be referred to as “blinking.” Over time, these portions can be accumulated in memory until a sufficient. Over time, these portions can be accumulated in memory until a sufficient amount of sniffing data has been acquired. Once sufficient data has been acquired, sniffing analysis can be performed in the background on the combined data.

  • Publication number: 20160066290
    Abstract: The present disclosure is directed to a system and method for performing timing synchronization via network listening. The system and method can be implemented in a non-synchronized base station to receive Cell-Specific Reference Signals (CRSs) of a synchronized base station during guard periods of special subframes. To allow the non-synchronized base station to receive the CRSs, the non-synchronized base station can configure one or more of its special subframes to have a shorter downlink part than corresponding special subframes of the synchronized base station. The system and method of the present disclosure can use the received CRSs to synchronize the timing of the non-synchronized base station to the timing of the synchronized base station. To prevent a substantial loss in downlink throughput due to the non-synchronized base station using a shorter DwPTS part, tracking can be performed on a once per multiple radio frame basis.

  • Patent number: 8934891
    Abstract: A system, method, and apparatus to facilitate the synchronization of oscillators between members of a Heterogeneous Network (HetNet) to form a self-synchronizing network (SSN). The network members are configured to broadcast information indicative of the reliability of their oscillator. Network members attempt to look for reliable sources such as those originating from a macrocell base station or GPS. If such a source is found, the member cell updates it clock accuracy confidence level number (CACL) to indicate this. Network members also share information regarding the frequency offsets between one another. Every cell member then applies a weighted average function to determine how to update its own oscillator and CACL value accordingly. Cell members can also update their functionality, such as RF power level, in response to varying degrees of CACL values. This operation results in a convergence of all cell members to the most accurate oscillator offset value.

  • Patent number: 8781497
    Abstract: Passive location determining of a 3G handset is provided. The method may include the following steps: sending a sequence of 3G ‘Pings’ directed at a specified handset over a 3G network; determining the specified handset user identifier and the sewing base station of the specified handset based on reoccurrences of user identifiers responsive of the ping requests, captured from the forward access channel (FACH) of each base station; decoding the FACH of the serving base station responsive to an additional ping, yielding parameters required for receiving uplink dedicated channel (UL DCH); estimating, in each location associated with a base station, a time difference between fastest possible and actual arrival of a signal over the UL DCH sent by the specified handset, wherein the estimating is synchronized to the serving base station; and calculating the location of the specified handset, based on the estimated time differences associated with the locations.
