  • Patent number: 9930716
    Abstract: Apparatus and methods to support IP flow mobility (IFOM) via multiple wireless accesses in a wireless device are disclosed. The wireless device initiates network-based IFOM (NB-IFOM) to establish and manage IP flows. Support for NB-IFOM is negotiated during initial attach procedures to either or both wireless accesses and by using packet data network (PDN) connectivity procedures. The wireless device sends routing rules including priorities to apply to both existing and future IP flows or to future IP flows only. The wireless device requests to move IP flows from a source access to a target access. When a new wireless access is added to an existing PDN connection, an identical IP address for the wireless device is allocated as used for the existing PDN connection. The network establishes a GPRS tunneling protocol (GTP) tunnel for the new wireless access while maintaining a previously established GTP tunnel for the existing wireless access.

  • Patent number: 9825674
    Abstract: The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.

  • Patent number: 9826101
    Abstract: Policies that govern allocation of spectrum access credentials are established. The policies are configured to implement regulatory rules governing spectrum use in a geographic area. Policy establishment includes selecting, from a collection of predetermined general policy constructs that are generic to plural regulatory domains, general policy constructs to transform into protection instances. Policy parameter inputs are applied to policy parameter fields of the selected general policy constructs to establish the protection instances, the protection instances specify how regulatory rules are applied in the geographic area. Protection data values are applied to protection data fields of the protection instances to create instances of policies that are specific to the geographic area according to incumbent spectrum use in the geographic area.

  • Patent number: 9794403
    Abstract: Performing data communications by a Dual SIM Dual Active (DSDA) user equipment (UE), while simultaneously conducting two concurrent voice calls. The UE may receive a request to perform data communications while conducting a first voice call on a first radio and concurrently conducting a second voice call on a second radio. The UE may then determine whether one of the voice calls is currently on hold. The UE may perform the data communications using the radio on which the held call is being conducted. The UE may therefore dynamically select available slots from the first radio and the second radio for performing the data communication, based on which of the first radio and the second radio has a voice call that is currently on hold. In some embodiments, the data communications may be performed using a Long Term Evolution (LTE) protocol stack.

  • Patent number: 9794872
    Abstract: A method and system for minimizing battery power consumption of user equipment (UE) during inter-frequency cell discovery in heterogeneous network is disclosed. UE receives background scan configuration for specified frequency from the network and performs the background scan for detecting inter-frequency cell. The UE detects an inter-frequency cell on the frequency indicated in the background scan configuration, during the inactive time of DRX cycle. Further, UE indicates the physical cell identity of the detected cell to the network. Then the UE activates the normal measurement gap provided previously or the network configures normal measurement gap to the UE if not provided previously. Further, UE performs Reference signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ) measurements of the detected cell. Then the UE reports these measurements to the network when the measurement report event condition is satisfied and the network handovers the UE to the detected cell.
