  • Patent number: 11445570
    Abstract: A mobile User Equipment (UE) uses Transmission Control Protocol (TCP) to deliver mobile data services over different radios. The mobile UE qualifies the individual radios that have adequate signal strength at a geographic location. The mobile UE estimates TCP retransmission rates at the location for the qualified radios. The mobile UE identifies individual qualified radios that have adequate TCP retransmission rate estimates. The mobile UE selects one of the identified radios that has the lowest power usage. The mobile UE exchanges TCP packets over the selected radio which includes participating in TCP retransmissions at the location. The selected radio wirelessly exchanges the TCP packets with a wireless access node. The mobile UE stores resulting TCP retransmission data for the selected radio in association with the location for future TCP retransmission rate estimates.

  • Patent number: 11388728
    Abstract: Methods, systems, and devices for wireless communications are described. A transmitter may identify a contention window for a no-energy-detection protocol for determining a channel availability for a data transmission. After the contention window expires, the transmitter may send a request message to a receiver. The receiver may measure a quality of the request message against a request threshold and transmit a response message if the measured quality exceeds the request threshold. The transmitter may then measure a quality of the response message against a response threshold. If the measured quality exceeds the response threshold, the transmitter may initiate a data transmission with the receiver. If the quality falls below the response threshold or the response message is not received, the transmitter may adjust the contention window and reattempt the no-energy-detection protocol. The contention window may also be adjusted based on an acknowledgement message received after the data transmission.

    Abstract: Systems and methods provide solutions for testing an 8Rx capable UE using test cases for 4Rx capable UEs. An example method establishes a connection from a first Tx source and a second Tx source to each of 8Rx antenna ports. The connection duplicates a fading channel from both the first Tx source and the second Tx source to each of the eight Rx antenna ports, and adds independent noise for each of the 8Rx antenna ports. One test scenario uses 4Rx supported RF bands by connecting four of the Rx ports with data from a system simulator, and the other four Rx ports are connected with zero input. Same requirements specified with 4Rx capable UEs are applied. Another test scenario uses 8Rx supported RF bands and applies lower dB SNR requirements than those specified for 4Rx tests.

Respective values for the composite indicator can be assigned in response to comparisons of the multiple signal strength indicators to one or more defined threshold(s). An idle time metric of the first channel can be determined based on a combination of the respective values and a best channel from among the group of frequency channels can be determined based on the idle time metric. The communication module can be updated to communicate via the best channel.

    Abstract: An in-flight entertainment system includes a plurality of static transceivers and an ISM band communication interference manager. The static transceivers are configured to transmit and receive radio frequency signals in the ISM band. The static transceivers are further configured to measure signals received within the ISM band from mobile transceivers within the aircraft and to measure signals received from proximately located ones of the static transceivers, and to generate measurement reports containing the measurements and containing identifiers of the proximately located ones of the static transceivers and the mobile transceivers. The ISM band communication interference manager is communicatively connected to the static transceivers, and performs operations that include receiving the measurement reports from the static transceivers, and controlling transmission power levels used by the static transceivers and the mobile transceivers responsive to the content of the measurement reports.

  • Patent number: 10628276
    Abstract: Aspects of the present invention provide an approach for integrated testing of gateway appliance software services. In an embodiment, a test request is received at a unit test framework installed on the gateway appliance. The unit test framework dynamically generates a set of stub code for processing the test request. This set of stub code executes target code (e.g., code that is being tested) of the software services. Results of the execution are verified to determine whether the code passes the test.

  • Patent number: 10631198
    Abstract: Systems and methods are described herein for identifying areas of maximum congestion so that small cells can be deployed at those specific sites to obviate network congestion problems. The systems and methods identify several input sources (e.g., call data records, passively collected data using Mobile app, etc.) that can be used to identify data congestion. The systems and methods divide a particular geographic area into smaller tiles of a certain shape (e.g., hexagon, square, etc.). For each of the geographic tiles, the systems and methods sort and group the input data samples based on their associated congestion discriminating characteristics (e.g., timestamps, type of input data, etc.). The systems and methods then compute a congestion index for each geographic tile area based on the grouped data samples. In this manner, the systems and methods identify geographic tile areas and time periods of high congestion.

  • Patent number: 10588090
    Abstract: In aspects of homogeneous and heterogeneous system determination in a network, a device can receive a first management frame and a second management frame communicated in separate data messages using a common communication protocol. The device implements a system identification module that can detect the first and second management frames are communicated in data messages from a radio device. The system identification module can determine that the first and second management frames are communicated from a homogeneous system that includes the radio device based at least in part on source addresses included in the first and second management frames. The system identification module can then determine to associate with the homogeneous system based on an operational state of services associated with either the first or the second management frames.
