  • Patent number: 10412597
    Abstract: Systems and methods for selectively enabling Robust Header Compression (RoHC) for Voice over Internet Protocol (VoIP) calls in a cellular communications network are disclosed. In one embodiment, a data radio bearer for a VoIP call is established between a base station and a mobile terminal. During the VoIP call, a radio frequency parameter for the data radio bearer is monitored. When the radio frequency parameter for the data radio bearer satisfies a predefined coverage-based condition, the base station enables RoHC for the VoIP call. In one preferred embodiment, the radio frequency parameter is a Signal-to-Interference-plus-Noise Ratio (SINR) for the data radio bearer for the VoIP call, and the predefined coverage-based condition is a predefined SINR threshold below which the base station enables RoHC. By enabling RoHC in this manner, RoHC resources are selectively made available for those VoIP calls that will benefit most from increased cell coverage provided by RoHC.

  • Patent number: 10375721
    Abstract: A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first.

  • Patent number: 10334521
    Abstract: An information processing device includes a wireless communication unit, a main system, and a subsystem. The information processing device is enabled to selectively execute a ready mode in which at least the main system in its entirety is activated, and a sleep mode in which at least a portion of the main system is not activated. When the information processing device transitions from the ready mode to the sleep mode, if the main system determines that the main system is connected to the wireless network and that peer-to-peer networking is ineffective, the main system carries out configuring of the subsystem to enable the subsystem to respond to the external device via the wireless communication unit during the sleep mode, and the main system transitions to, as the sleep mode, a first sleep mode in which the subsystem is activated without the main system in its entirety being activated.

  • Patent number: 10212125
    Abstract: The subject matter described herein relates to methods, systems, and computer readable media for testing network equipment devices using connection-oriented protocols. In some examples, a method for testing a network equipment device under test (DUT) includes executing, by a network equipment test device, a test script to test the network equipment DUT using a connection-oriented protocol. The method includes inserting, during a connection establishment process of the connection-oriented protocol for a network flow to the network equipment DUT, a flow-identifying sequence number into a sequence number field of a first message of the network flow. The flow-identifying sequence number is a number uniquely identifying the network flow from other network flows. The method includes receiving a second message from the network equipment DUT and determining that the second message belongs to the network flow by extracting the flow-identifying sequence number from the second message.

  • Patent number: 10212648
    Abstract: Systems and methodologies are described that facilitate efficient cell acquisition in a wireless communication system. In one aspect, a reference signal for use in cell acquisition can be constructed in a bandwidth-agnostic manner such that it contains a common central portion in a predetermined frequency band that is independent of a bandwidth utilized by an associated wireless communication system. The central portion can be constructed as a two-dimensional block in time and frequency that spans a default cell search bandwidth, a predetermined bandwidth specified by synchronization codes or other signals, or another suitable bandwidth. A reference signal can then be constructed form the central portion by tiling or expanding the central portion such that it spans the entire system bandwidth.
