  • Patent number: 9215658
    Abstract: The present invention provides a method and a device for adjusting the sleep mode of a mobile station in order to solve the problem in current multi-hop relay systems of long time delays in data transmission caused when data packets have to wait for the next listening window to reach the mobile station because of packet errors. Wherein, a relay apparatus judges whether the previous hop network apparatus needs to retransmit data packets to the mobile station; when the previous hop network apparatus needs to retransmit data packets to the mobile station, the relay apparatus transmits to the mobile station the adjustment related information for adjusting the sleep mode of the mobile station. The mobile station adjusts the sleep mode according to the adjustment related information. Preferably, the adjustment related information comprises indicating information for indicating that the mobile station is in triggered listening status within predetermined time interval.

  • Patent number: 9173154
    Abstract: A wireless device can initiate a network connection without using a network operator's home location register. The wireless device sends data to a server that defines a call request; and the server decides on the appropriate routing over all available networks for that call request. But, unlike a conventional HLR, the server can receive communications from the device using any one of several different protocols, and is not limited to the MAP (mobile application part) protocol. For example, the wireless device can use SMS or HTTP over the internet to communicate with the server. The server then determines the appropriate least cost routing.

  • Patent number: 8886115
    Abstract: A method for controlling gain in a wireless repeater includes computing a gain control metric indicative of a loop gain of the repeater and detecting changes in a signal power of a gain control input signal where the gain control input signal is taken from any point in the feedback loop of the repeater. When a large power swing in the gain control input signal is detected, the method operates to discard at least a portion of each gain control metric measurement for a first duration before continuing with computing the gain control metric. In another embodiment, the method may include discarding samples of the gain control input signal used in computing the gain control metric for a first duration when a large power swing in the gain control input signal is detected.

  • Patent number: 8867429
    Abstract: Plural repeaters (1111 to 111n) are connected one another via a system bus (115), and each of which detects the state of another repeater by checking a signal transmitted over the system bus (115). When stopping the operation of home repeater (e.g., the repeater (1111)) which performs relaying process among wireless terminal devices (TA) to (TH), a secondary repeater (e.g., the repeater (1112)) set beforehand detects that the home repeater breaks down as the secondary repeater becomes unable to detect the signal over the system bus (115). The secondary repeater responds to the detection and bears the relaying process instead of the home repeater.

  • Patent number: 8867987
    Abstract: A method for computing a gain control metric used in controlling gain in a wireless repeater operates to store correlation and normalization values associated with the gain control metric for the previous N samples in registers. For each new sample of the gain control input signal, the correlation and normalization values are computed by discarding the multiplication terms of the obsolete sample and adding the multiplication terms of the new sample to the stored correlation and normalization values. In this manner, the complexity of the computation is greatly reduced and the complexity of the computation does not increase with the integration length.
