  • Patent number: 10212617
    Abstract: A method of throughput and data volume measurement for minimization of drive test (MDT) is proposed. A base station establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The base station or UE measures transmitted or received data volume during a transmission time of a data burst between the base station and the UE. When the data burst spans multiple measurement periods and the data burst is split at each measurement period boundary. For each measurement period, data volume during the measurement period is measured to generate a measurement result. When throughput measurement is performed by the network, the base station receives location information that is available during the transmission time of the data burst. The data volume measurement is logged with time stamp such that each measurement result can correlated with the location information.

  • Patent number: 10200958
    Abstract: In order to solve a problem in which when a terminal is converted from an active state of transmitting data to an inactive state, the transmission power of the terminal rapidly increases, a base station can control the transmission power by predicting and reflecting, in a target SIR, a decrease in SIR which results from an increase in interference amount due to data transmission of another terminal. The present invention can ensure the quality of an uplink control channel by controlling power in consideration of the effect of interference, even when the terminal is in an inactive state.

  • Patent number: 10021548
    Abstract: Encoding and decoding schemes at an encoding device/transmitter and decoder device/receiver, respectively, for use in communicating the state of a system. In an example method carried out by an encoding device, state information x(k), which represents the current state of a monitored system, is measured. The encoding device calculates a state update parameter, based on: a message power constraint P; the covariance N of measurement noise associated with the channel over which encoded state information is to be transmitted; and the norm of the signal vector [s(k), x(k)], where s(k) is a stored state information parameter. The encoding device then calculates a message signal z(k)=G(k)*(x(k)?s(k)), which may then be transmitted to a remote decoder device, and calculates an updated version of the stored information s(k+1)=A*(s(k)+F(k)*z(k)). The encoding device replaces the stored state information s(k) with s(k+1).

  • Patent number: 10015808
    Abstract: Provided are resource-utilization controlling methods for a device-to-device communication and wireless devices therefor. The method performed by a first wireless device comprises steps of: detecting current utilization state of the resource for the device-to-device communication as a resource utilization state; and explicitly or implicitly signaling the resource utilization state through broadcasting in the physical layer. The method performed by a second wireless device comprises steps of: receiving one or more resource utilization states explicitly or implicitly signaled from one or more other wireless devices; and determining whether and/or how to adjust the transmission behavior of the second wireless device based on the received one or more resource utilization states.

  • Patent number: 9980310
    Abstract: A method of enhanced session management procedure is proposed. A user equipment, upon receiving a rejected PDN connectivity request with a cause code, automatically alters the rejected factor to fit network restrictions based on the received cause code. The UE then retries the PDN connectivity procedure by sending a subsequent PDN connectivity request using the altered factor. By automatically altering the rejected factor and reattempting to establish an EPS bearer for data service without user interaction, possible permanent rejection can be avoided in case of user error or unawareness.

  • Patent number: 9980192
    Abstract: A method and apparatus are disclosed for steering a UE (103) from a WLAN (105) to a cellular network (106) with an overlapping coverage area. The UE (103) is connected to the WLAN (105) through an access point (AP) (102). The AP (102) suppresses the broadcast of a network identifier of the WLAN (105) and de-authenticates the UE (103) from the WLAN (105). After de-authenticating the UE (103), the AP (102) ignores probe requests from the UE (103). The UE (103) will conclude that the WLAN (105) is no longer available and will connect to the cellular network. From the perspective of the UE (103), the suppression of the network makes it appear to the UE (103) that it has moved out of range of the AP (102) so the UE (103) will not “blacklist” the WLAN (105). The suppression of the network ID will not impact UEs not targeted, which will continue to communicate via WLAN (105) even when the network ID is suppressed.

  • Patent number: 9900251
    Abstract: Minimum guaranteed wireless network bandwidth is provided to client network devices by monitoring the performance of network connections to identify client network devices experiencing network congestion. Congested network connections are then analyzed to determine the source of the network congestion. Depending upon the source of the network congestion, an embodiment of the invention may undertake steps to either improve the quality of the network connection or to mitigate the impact of this network connection on other network connections. High quality network connections may be allocated additional bandwidth, airtime, or other resources to reduce the network congestion. Low quality network connections are not allocated additional bandwidth, airtime, or other resources. Instead, the impact of this network connection on the other network connections is mitigated.
