摘要： A reverse link load control strategy utilizes a total call load metric in place of a reverse signal strength indicator metric for managing reverse link resources. In a disclosed example, a load control module (40) measures the reverse signal strength indicator (62) and measures an active cell load (64) using known techniques. A relationship between the reverse signal strength indicator, the active cell load, an other cell load component and a jammer component provides the ability to determine the other cell load component and the jammer component. Once the other cell load component has been determined, a total call load based upon the active cell load component and the other cell load component provides a useful metric for allocating reverse link resources between existing users and for determining whether to allow a new user, for example.

摘要： A method/apparatus identifies other cell interference in a wireless network and determines whether a handoff to an affected base station should occur. In one implementation, a base station of a CDMA-based wireless network continuously monitors reverse link interference levels to detect an increased interference condition, and initiates a CDMA mobile identifying sequence to determine whether the interfering signal source is a proximate mobile being served by a neighboring base station of the network. The affected base station obtains a list of long code masks for mobiles being served by neighboring base stations, and instructs at least one receiver unit to sequentially despread received signals using each of the listed long code masks. When the receiver unit detects a signal transmitted by a non-served mobile, the base station analyzes relative reverse link signal strength for the non-served mobile, e.g., using Ec/Io measurements, to determine whether the non-served mobile is likely be the source of interference. Having determined that a nearby CDMA mobile is the source of interference, the affected base station may initiate one of a number of possible actions, including triggering a handoff to the affected base station so that the affected base station could control the transmit power level of the mobile, requesting that the interfering mobile be switched to a different frequency carrier or dropped, or merely recording the interference condition.

摘要： Inter-frequency handoffs in a CDMA or other wireless communication system are controlled using a noise-limited coverage trigger metric which is able to distinguish between same-frequency cell boundaries and other-frequency cell boundaries in the system. The trigger metric may be generated as a function of an average signal-to-noise measure for pilot signals received at a mobile station of the system and a linear sum of the signal-to-noise measures. The signal-to-noise measures may be generated in the mobile station and included in messages transmitted from the mobile station to one or more base stations of the system. The trigger metric is used to control a handoff from a current frequency to a new frequency in an ongoing call. The trigger metric may alternatively be based on a measure of mobile receive power alone. Other aspects of the invention reduce unnecessary searching for a new frequency and decrease the likelihood of “ping-ponging” from a current frequency to a new frequency by providing additional checks in the handoff process. For example, receive power and pilot signal-to-noise measures may be generated at a mobile station for both current and new frequencies. The mobile station then continues to operate at the current frequency as long as certain predetermined threshold conditions based on the measures are satisfied.

摘要翻译： CDMA或其他无线通信系统中的频率间切换是使用能够区分系统中的同频小区边界和其它频率小区边界的噪声限制覆盖触发度量来控制的。可以根据在系统的移动台处接收的导频信号的平均信噪比测量值和信噪比测量的线性和来产生触发度量。信号噪声测量可以在移动台中产生，并且包括在从移动站发送到系统的一个或多个基站的消息中。触发度量用于控制正在进行的呼叫中从当前频率到新频率的切换。触发度量可以替代地基于单独的移动接收功率的量度。本发明的其他方面通过在切换过程中提供额外的检查来减少对新频率的不必要的搜索并且减少从当前频率到新频率的“乒乓”的可能性。例如，可以在移动台处为当前和新频率产生接收功率和导频信号噪声测量。只要满足基于措施的某些预定阈值条件，移动台就继续以当前频率工作。

摘要： Telecommunications processing is applied to a reference signal to generate a signal under test. A fidelity measure is generated characterizing the fidelity of the signal under test relative to the reference signal. A control signal is generated from the fidelity measure, where the control signal is used as a feedback signal to adjust the telecommunications processing. In one embodiment, the reference signal is a speech signal and the signal under test is a decoded speech signal generated by encoding, transmitting, and decoding the reference speech signal. The fidelity signal is an average mean opinion score (MOS) and the control signal is used to control the speech decoding processing. For example, the speech decoding processing may involve a speech decoder followed by a post filter, and the control signal is the cut-off frequency of the post filter. Such an embodiment may be applied to real-time speech processing to adjust the speech decoding processing in the receiver of a telecommunications system that includes a speech encoder in a transmitter and a communications network. Intermittently, the transmitter encodes reference signals that are also known to the receiver. The receiver performs the processing of the present invention to update its speech decoding processing to optimize speech quality.
