  • Patent number: 11012504
    Abstract: Various exemplary embodiments relate to a method for determining whether to admit a query in a network, the method including determining a load for a network element type based on an adaptive history for that network element type; determining a cost of admitting the query based on the relative load that the query generates accounting for the amount of traffic the network element has admitted in the past; decreasing a total cost of all queries that can be budgeted during a subsequent interval when the change in load is within a specified range; increasing the total cost of all queries that can be budgeted during a subsequent interval when the change in load is below a threshold; and adding the query to a data structure which keeps track of potentially admittable queries.

  • Patent number: 10292205
    Abstract: A cellular-WLAN integration capability is presented herein. The cellular-WLAN integration capability provides an integration of a cellular network and a WLAN network that supports more efficient routing of downlink and uplink bearer traffic via cooperation of the cellular and WiFi interfaces in both the radio access network and at the end user device. The cellular-WLAN integration capability provides an integration of a cellular network and a WLAN network in which downlink bearer transmissions to an end user device may be selectively distributed between the cellular and WLAN networks and, similarly, uplink bearer transmissions from an end user device may be selectively distributed between the cellular and WLAN networks. The cellular-WLAN integration capability provides an integration of a cellular network and a WiFi network that tends to increase capacity for downlink bearer traffic while providing a reliable and efficient path for uplink bearer traffic.

  • Patent number: 10148825
    Abstract: A base station receives packets at a base station in a first network that operates according to a first radio access technology (RAT).

  • Publication number: 20180049156
    Abstract: A broadcast manager identifies a time interval that encompasses paging windows for a plurality of user equipment. The plurality of user equipment operate according to a plurality of discontinuous reception cycles that include sleep intervals separated by the paging windows. The broadcast manager generates messages for wireless transmission to the plurality of user equipment in corresponding paging windows during the time interval. The messages include information indicating a transmission time at which the plurality of user equipment are to receive broadcast or multicast data. The transmission time is subsequent to the time interval.

  • Patent number: 9866334
    Abstract: Successfully decoded data received from a mobile terminal as well as the transmission format of that data is relayed over the backhaul from a base station receiver that successfully decoded the mobile terminal's transmission to the base stations in the mobile terminal's active set that presumably were unable to decode the mobile terminal's transmission due to inadequate signal-to-noise ratio. A base station that receives this transmission from the relaying base station that did successfully decode and demodulate the mobile terminal's transmission is then able to reconstruct the data and subtract it from the total interference, thereby increasing the signal-to-noise ratio at this base station for its in-cell processing.

  • Patent number: 9807620
    Abstract: A method is provided a wireless system for providing small “guard” cells in a heterogeneous network at locations proximate to privately-maintained HeNB (or femto) cells in the heterogeneous network. More particularly, the methodology of the invention addresses the problem of a mobile user in a heterogeneous network located nearby to a privately maintained HeNB cell in the heterogeneous network, and the inherent interference created for the HeNB cell by the necessity of the mobile user having to transmit and receive communications from a distant public macro eNB. By deploying small public “guard” cells in the macro cell proximate to the private HeNB cells, such a public mobile terminal is enabled to communicate with the public small cell at generally lower power than would have been necessary for communication with the distant macro eNB, with a resulting reduction in interference for the nearby HeNB cell. The FL interference between the macro cell and the HeNBs is also mitigated.
