Patent number: 9179384Abstract: A map-based mobility robustness optimization (MRO) capability is provided for improving one or more aspects related to mobility in a wireless communication network. The map-based MRO capability may use one or more reference signal strength map associated with a wireless network to determine at least one management function for the wireless network. The at least one management function may include determining at least one configuration action adapted to satisfy a handover failure rate for the wireless network based on the one or more reference signal strength maps, preventing handover race conditions in a cluster of wireless cells covered by the one or more reference signal strength maps, or the like. The one or more management functions may be adapted to improve or optimize one or more of handover failure rate, prevention of handover race conditions, or the like.Type: GrantFiled: December 31, 2012Date of Patent: November 3, 2015Assignee: Alcatel LucentInventor: Carl F.

Patent number: 8437794Abstract: Example embodiments are directed to a method of determining an uplink target signal-to-interference-and-noise ratio (SINR). In one embodiment, the method includes determining the uplink target SINR for a user equipment (UE) based on a downlink signal-to-interference ratio (SIR). The downlink SIR is determined based on a channel quality indication (CQI) index received from the user equipment.Type: GrantFiled: January 28, 2010Date of Patent: May 7, 2013Assignee: Alcatel LucentInventors: Carl F.

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. Meyers, Alexandro Salvarani, Carl F. Weaver

Patent number: 6606496Abstract: 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.Type: GrantFiled: August 25, 2000Date of Patent: August 12, 2003Assignee: Lucent Technologies Inc.Inventors: Alexandro Salvarani, Carl F.

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.
