摘要： A system and method for measuring the Ricean K-factor of a wireless channel in real time are provided. An amplitude sample of a transmitted RE waveform of either fixed or varying amplitude is low-pass filtered to eliminate high frequency noise if present. The magnitude squared of the filtered sample amplitude is squared to obtain the power gain of the sample and the magnitude squared of the power gain is computed. The sums of a window of power gains and the sum of the squares of the power gains are then updated. These sums of the window of amplitude samples are then averaged to estimate the first and second moments of the window of samples. The averages are low-pass filtered to minimize fluctuations. The final average is input to a moment-based set of Greenstein-Michelson-Erceg (GME) equations to obtain estimates for the time average of the power gain and rms deviation of the power gain. The K-factor is calculated in accordance with these equations and low-pass filtered to smooth the result.

摘要： A data communications system includes a controller device and multiple client devices communicating with the controller device through a shared data communications link. The controller device is configured to determine a usage based multiplier value for each of the client devices and monitor the data communications link for congestion. When it is determined that a threshold congestion level has been exceeded, the controller applies a rate-limiting scheme, based on the determined usage based multiplier values, to reallocate client device bandwidth over the data communications link.

摘要： A system and method are described for reducing congestion in a wireless network. A wireless base station becomes congested when substantially all of the available base station airlink resources are being used during a period of time. It is useful, however, to distinguish between periods of congestion with few users and periods where a larger number of users are using the base station. When there are few users a congestion situation is not necessarily a problem, while it is more likely that users' quality of experience and quality of service suffers as the number of users increases. This system and method determines when a base station is congested and implements a congestion prime management scenario when the number of active users is above an activity threshold.

摘要： A networked computing system that utilizes a hybrid rate-limiting scheme to jointly affect both PDU payload throughput and total PDU throughput. The networked computing system includes one or more service provider devices (SPDs), one or more subscriber computing devices (SCDs), and a data communications network facilitating data communications between a SPD and a SCD. The SPD can apply the hybrid rate-limiting scheme to data communications provided to the SCD, based on both protocol data unit (PDU) header and payload characteristics. The hybrid rate-limiting scheme can simultaneously facilitate rate-limiting PDU payload throughput and rate-limiting total PDU throughput.

摘要： A method of supporting voice-band modem-to-modem calls in a wireless communication system is disclosed. In some embodiments, once a modem call is detected, the modem call is terminated. Data in the terminated modem call is then demodulated and relayed from one end of a wireless broadband channel to the other end of the wireless broadband channel. Transfer of the data to the second modem is completed when the other end of the wireless broadband channel places a modem call to the second modem. By sending data in high-rate modem calls via a wireless broadband channel rather than over multiple, dedicated wireless voice channels, resources of the wireless communication system are utilized more efficiently that can result in significant gains in system capacity.

摘要： A wireless device includes a data structure that relates peak channel capacity to the quality of the wireless communication link. The wireless communication link quality forms an index to indicate the expected peak channel capacity for that particular quality value of the wireless communication link. The wireless device uses the data storage structure to determine an expected data transfer throughput based on the quality of the wireless communication link. A transfer rate lower than expected may indicate congestion in the core network or the RAN. In this case, the network may slow the data delivery from the data source or temporarily suspend delivery. Conversely, low data throughput may be the result of a poor quality wireless communication link. If the data structure indicates that the data throughput corresponds to the expected throughput for the quality value of the wireless communication link, the system need not take any steps to reduce congestion.

摘要： A wireless communications system includes a radio resource manager, one or more base stations, and one or more wireless transceivers capable of communicating with the base stations. The wireless transceivers are configured to be able to measure the difference in network parameter (e.g. frequency and timing offset) between base stations within their range. These network parameter differences along with other information are communicated to the radio resource manager which is then able to update or correct the signal or signals of one or more base stations using the information from the wireless transceivers.
