  • Patent number: 9253025
    Abstract: In one example, a network device includes one or more network interfaces configured to receive a message according to a protocol for reserving a public Internet protocol (IP) address and port for a network connection and to receive one or more packets of a packet flow associated with the public IP address and the port for the network connection, and one or more processors comprising a primary service device, wherein the processors are configured to determine whether the message includes an indication that the network connection is to be checkpointed for high availability, and wherein the primary service device is configured to, based on the indication, checkpoint data of at least one of the received packets to a backup service device. Accordingly, a message of a protocol for reserving a public network address and port may be used to indicate whether a network connection should be checkpointed for high availability.

  • Patent number: 9253720
    Abstract: One or more mobile devices and a cloud server computing device are utilized to provide Internet access to one or more client computing devices. One of the clients is designated as a Wi-Fi access point. The Wi-Fi access point implements a reverse-infrastructure Wi-Fi mode which tethers available mobile devices and other clients to the access point. The cloud server periodically computes an optimal number of the mobile devices to be used for data striping, and transmits a webpage to a requesting client by striping data associated with the webpage across the optimal number of the mobile devices.

  • Patent number: 9253698
    Abstract: Embodiments of system, device, and method configurations for managing inter-radio access technology (inter-RAT) mobility of handovers between a UMTS Terrestrial Radio Access Network (UTRAN) or GSM EDGE Radio Access Network (GERAN) and an evolved UMTS Terrestrial Radio Access Network (E-UTRAN) to avoid scenarios of in-device coexistence (IDC) interference are disclosed herein. In one example, the existence and types of IDC interference with an E-UTRAN Long Term Evolution (LTE)/Long Term Evolution-Advanced (LTE-A) network are determined and communicated to the UTRAN/GERAN in an IDC indication signal. The IDC indication signal may communicate the existence and type of IDC interference occurring at user equipment, such as between licensed LTE/LTE-A and unlicensed industrial scientific medical (ISM) radio frequency bands. Accordingly, the UTRAN/GERAN may use information provided from the IDC indication signal to prevent a handover to the E-UTRAN that would result in IDC interference.

  • Patent number: 9253745
    Abstract: In a communication system, an access point in communication with one or more stations is configured to shift the start of transmission of its downlink data. The access point may automatically shift the transmission of the downlink data in response to receiving downlink data transmitted by a neighboring access point. Shifting the start of transmission of its downlink data permits stations to correctly synchronize to the downlink data. The transmission of data may be synchronized to a synchronization event. In some instances, the access point updates its downlink data with a value corresponding to the shift. The access point may not shift the transmission of the downlink data if the signal strength of the received downlink data is below a threshold.

  • Patent number: 9220115
    Abstract: Techniques are described for channel access in a radio frequency spectrum band shared by a number of asynchronous operators. One or more clear channel assessment (CCA) procedures may be used to contend for one or more transmission periods in the radio frequency spectrum band. When the contention is won for one or more transmission periods, a determination may be made as to whether the a number of transmission periods for which contention has been won is equal to or greater than a threshold number of consecutive transmission periods. If the number of transmission periods for which contention has been won is at or above the threshold number, occupancy of the radio frequency spectrum band may be relinquished for a period of time, in order to allow another operator to access the radio frequency spectrum band.

  • Patent number: 9210668
    Abstract: Techniques for mitigating interference due to peer-to-peer (P2P) communication are described. In an aspect, a P2P UE may measure the signal strength of downlink signals from base stations and may set its transmit power based on (e.g., proportional to) the measured signal strength in order to mitigate interference to WWAN UEs communicating with base stations. In another aspect, the P2P UE may measure the signal strength of uplink signals from WWAN UEs and may set its transmit power based on (e.g., inversely proportional to) the measured signal strength in order to mitigate interference to the WWAN UEs. In one design, the P2P UE may measure the signal strength of an uplink signal from a WWAN UE, estimate the pathloss between the two UEs based on the measured signal strength, and determine its transmit power based on the estimated pathloss.

  • Patent number: 9204320
    Abstract: Systems (100) and methods (200) for dynamically managing Functional Configurations (“FCs”) of network nodes (104, 134-138). The methods involve performing operations by a First End Node (“FEN”) in accordance with a first FC. FEN (104) has a first Software Module (“SM”) stored thereon specifying the first FC. The first SM (122) comprises a total set of codes/functions which determine how a network node is to behave. The first EN detects a trigger event for triggering a transition from the first FC to a second FC. In response to the trigger event, the FEN automatically and dynamically obtains, from a remote network node (134, 136, 138 or 144), a second SM (150 or 126) that is different than the first SM. The first SM (stored on FEN) is then replaced with the second SM. The FEN executes the second SM such that it operates in accordance with the second FC.
