  • Patent number: 10326540
    Abstract: A method for coordinating testing of a wireless device under test (DUT) using non-link testing resources. Coordination between the tester and DUT is achieved by transmitting, from the tester to the DUT, predetermined numbers of data packets associated with predetermined tester identification data (e.g., MAC addresses identifying the tester transmitter). During test phases involving measurement and/or calibration of DUT transmit signals, the tester sends a number of data packets associated with one or more versions of tester identification data, in response to which the DUT performs internal operations (e.g., revising transmit power offsets). During later test phases involving validation of DUT performance, the tester sends another number of data packets associated with one or more versions of the tester identification data to inform the DUT that its testing has passed or failed, and/or is to be repeated.

  • Patent number: 10310518
    Abstract: A system and method for generating an artificial topography in a distributed array of robotic agents. Each robotic agent stores, and periodically updates a parameter value or “A-value” in accordance with a process including, e.g., averaging neighboring A-values, received from close neighbor robotic agents, biasing the A-value based on external commands or measured environmental parameters, and decreasing the A-value by a cooling rate factor. Averaging among neighboring robotic agents results eventually in a globally smoothed distribution of A-values. A gradient may be estimated for the distribution of A-values, and the robotic agents may be programmed to move in the direction of the gradient, toward increasing A-values. This behavior may be employed to cause the robotic agents to follow a robotic agent with a fixed, relatively large, A-value, or, if the A-values are biased by features (e.g., gradients or steps) in environmental parameters, to converge on such features.

  • Patent number: 10172148
    Abstract: A data-storing-terminal counting unit counts the number of communication terminals in which each of a number of data are stored. Based on the results of the counts, a communication terminal count estimation unit estimates the number of communication terminals that will transmit data with the same timing. An adjustment reference value calculation unit computes an adjustment reference value for constraining the number of communication terminals estimated by the communication terminal count estimation unit to be less than or equal to a preset allowable number. On the basis of the adjustment reference value computed by the adjustment reference value calculation unit, a determination unit determines whether or not to permit transmission of data stored by a storing means. If the determination unit permits the transmission of said data, a data transmission unit transmits the data to a communication terminal in which said data is not stored.

  • Patent number: 10142436
    Abstract: Described herein are techniques and systems for controlling a broadcast mode and a timer mode to update data stored in respective caches of multiple cache servers. When a cache server is operating in the broadcast mode, the cache server receives a data update or a notification of a data update from a broadcast server. When a cache server is operating in the timer mode, the cache server updates its cache without the use of, or reliance upon, the broadcast server. A cache server is configured to operate in the broadcast mode based on a determination that the broadcast server is capable of broadcasting (e.g., sending) messages and/or data updates to the cache servers. In contrast, a cache server is configured to operate in the timer mode based on a determination that the broadcast server is incapable of broadcasting messages and/or data updates to the cache servers.

  • Patent number: 10142203
    Abstract: Ethernet fault management systems and methods using programmable Type-Length-Value (TLV) offsets combine software-based Operations, Administration, and Maintenance (OAM) protocol support with hardware-based fault management support to delegate generation and processing of OAM protocol messages to hardware devices with the software-based protocol support used to program hardware based on fixed offsets in the OAM protocol messages. The hardware can be designed to be flexible since the hardware can be agnostic to the logic within the OAM protocol which would reside in the software. The Ethernet fault management systems and methods combine the flexibility of software-based approaches with the speed and efficiency of hardware-based approaches.

  • Patent number: 10122700
    Abstract: Upon receiving a triggering message from a MTC server (20), a network (10) verifies if the MTC server (20) is authorized to trigger a target MTC device (30) and also if the MTC device (30) is authorized to respond the triggering message, by comparing an MTC device ID and MTC server ID (and optionally information on subscription) which are include in the triggering message with authorized ones. Upon succeeding in the verification, the network (10) checks a trigger type included in the triggering message to verify if the triggering message is authorized to be sent to the MTC device (30). Upon succeeding in the check, the network (10) forwards the triggering message to the MTC device (30). The network (10) also validates a response from the MTC device (30), by checking whether the MTC device (30) is allowed to communicate with the addressed MTC server (20).
