Patent number: 8219106Abstract: 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.Type: GrantFiled: September 7, 2005Date of Patent: July 10, 2012Assignee: Alcatel LucentInventors: Martin H.

Patent number: 7647050Abstract: A method of adjusting a power level of communications over a channel in a wireless communications network. In the method, a determination (e.g., by a radio network controller (RNC)) is made regarding a number of base stations actively communicating with a mobile station. For example, the determination may indicate whether the mobile station is engaged in soft handoff or simplex mode. One of a plurality of power control algorithms (e.g., a fixed offset power control algorithm, a channel quality indicator (CQI) power control algorithm, etc.) is selected based on the determination. A power level of communications over the channel (e.g., a downlink communications channel to the mobile station) is then adjusted in accordance with the selected power control algorithm.Type: GrantFiled: December 28, 2005Date of Patent: January 12, 2010Assignee: Alcatel-Lucent USA Inc.Inventors: Francis Dominique, Ali Masoomzadeh-Fard, Martin H. Meyers, Walid E. Nabhane

Patent number: 7583637Abstract: In an aspect of the method, a received data packet is decoded in order to determine a packet error rate value, and an average package error value for N received data packets is updated based on the determined packet error rate value. The updated average packet error rate value is then compared against a threshold value and a data rate request is issued based on this comparison. In another aspect, a response to a transmitted data packet is received, the response being related to an average packet error rate value. The average packet error rate value is compared against a threshold and a data rate is modified based on the comparison. In each of the above aspects, a data rate control margin that is used to overcome channel estimate errors resulting from transmission delays may be dynamically adjusted, e.g., in real time, in order to optimize system resources.Type: GrantFiled: January 31, 2003Date of Patent: September 1, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Kin Nang Lau, Youjian Liu, Martin H.

Publication number: 20090059831Abstract: A disclosed method of communicating includes using a group identifier within a multi-user packet (MUP) to indicate at least one packet within the MUP is intended for a plurality of members of a group corresponding to the group identifier. In a disclosed example, the group identifier comprises a group MAC identifier that is included in a header of the MUP. Mobile stations receiving the MUP process the MUP to determine whether any individual user identifier or any group MAC identifier within the MUP indicates that an associated packet is intended for that mobile station. If so, the mobile station proceeds to process the associated packet or packets from within the MUP.Type: ApplicationFiled: August 28, 2007Publication date: March 5, 2009Inventors: Gang Li, Ming Lu, Martin H.

Patent number: 7489929Abstract: A wireless communication network (20) utilizes a hard handoff procedure for switching between cells serving a mobile station (40). In a disclosed example, the existing link between the mobile station (40) and a serving base station (38) is not released until a new link between a target base station (32) and a mobile station (40) is established. At the same time, however, the mobile station maintains only one base station or link within its active set at all times. The disclosed example is useful for dedicated channel and shared channel communications in CDMA systems, for example.Type: GrantFiled: March 31, 2005Date of Patent: February 10, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Suman Das, Ali Masoomzadeh-Fard, Martin H.

Patent number: 7245919Abstract: A method of processing, in parallel fashion, messages from a User Equipment (UE) in soft handoff with a plurality of base stations of a wireless communication system. Measurement Messages from the User Equipment are received and stored in a message buffer for a defined period of time. Later arriving messages replace previous messages during the defined period of time. When the defined period of time elapses, the latest stored message is processed in parallel fashion in a processing pipeline with other messages for the UE and other UEs. The latest message is processed by first converting it to soft handoff actions and inserting such actions into a processing pipeline. A conflict table is generated during the parallel processing of the soft handoff actions to avoid the processing of messages that conflict with each other. Conflicting messages are put into a pending state and remain in such state until they are canceled by subsequent messages or the conflict no longer exists.Type: GrantFiled: June 19, 2003Date of Patent: July 17, 2007Assignee: Lucent Technologies Inc.Inventors: Kin Nang Lau, Ali Masoomzadeh-Fard, Martin H.

Patent number: 6766164Abstract: An apparatus and a method for recreating radio frequency (RF) conditions of a cellular network extracts significant RF effects from field test data, and recreates variable RF attenuation using a multi-channel attenuator. A field data processor converts the field test data to time-varying attenuator control values for each channel of the multi-channel attenuator. Accordingly, a mobile in the lab which is connected to the multi-channel attenuator sees the same carrier and interference levels that were observed in the field environment, allowing cellular communication equipment testing without repeated field testing.Type: GrantFiled: January 19, 1999Date of Patent: July 20, 2004Assignee: Lucent Technologies Inc.Inventors: Robert B.

Patent number: 6574203Abstract: 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.Type: GrantFiled: June 25, 2001Date of Patent: June 3, 2003Assignee: Lucent Technologies Inc.Inventors: Neil E. Bernstein, Xiao C. Bernstein, Wen-Yi Kuo, Martin H. Meyers, Xiao Wang, Carl F. Weaver

Patent number: 5978783Abstract: 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.Type: GrantFiled: June 25, 1997Date of Patent: November 2, 1999Assignee: Lucent Technologies Inc.Inventors: Martin H.

Patent number: 5715372Abstract: The present invention provides a method and apparatus for measuring at least one signal characteristic. Initially, a set of features is selected which characterize a signal. An intelligent system, such as a neural network, is trained in the relationship between feature sets and signal characteristics. The selected feature set is then extracted from a first input signal. The extracted feature set from the first signal is input to the trained intelligent system. The intelligent system creates an output signal based on the feature set extracted from the first input signal. This output signal is then used to characterize the input signal. In one embodiment, the invention assesses voice quality, typically as expressed in MOS scores, in a manner which accurately corresponds to the analysis of human evaluators. For voice signals processed by voice coders, the present invention provides a measurement technique which is independent of various voice coding algorithms and consistent for any given algorithm.Type: GrantFiled: January 10, 1995Date of Patent: February 3, 1998Assignee: Lucent Technologies Inc.Inventors: Martin H.

Patent number: 4759036Abstract: An improved decision-directed control circuit is disclosed which supplies adjustments to adaptive circuitry in a communications system. The improvement is achieved by only supplying adjustments when there is a high probability that the adjustment is correct. In the disclosed embodiments, this high probability equates, at a minimum, to times when the adaptive circuit output has an amplitude which lies outside of a range extending from the largest to the smallest value of the digital signal. This adjustment approach can be used to adjust a variety of adaptive circuits including transversal equalizers, timing recovery circuits, cross-polarization cancellers and carrier recovery circuits.Type: GrantFiled: March 2, 1987Date of Patent: July 19, 1988Assignees: American Telephone and Telegraph Company, Bell Telephone Laboratories, IncorporatedInventor: Martin H.
