Patent number: 11018820Abstract: In one aspect, the present invention provides a simple method of signaling reference signal muting information to receiving radio equipment, such as items of user equipment (UEs). The reference signals may be positioning reference signals and/or cell-specific reference signals, for example. In one or more embodiments, the present invention proposes a general solution whereby the receiving radio equipment is informed not only on whether muting is used in general in a cell, but also the particular timing and formatting of such muting. Further, the contemplated method provides for the use of dynamic muting patterns, and thus avoids the need for statically defined muting patterns, and provides for coordinated muting control, across two or more network cells. In at least one embodiment, static or less dynamic aspects of the muting configuration is signaled via higher-layer signaling, while lower-layer signaling is used to signal more dynamic aspects of the muting configuration.Type: GrantFiled: October 16, 2015Date of Patent: May 25, 2021Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Iana Siomina, Muhammad Ali Kazmi

Patent number: 7515927Abstract: A closed loop power control based on receiving a continuous quality feedback is described. A main reverse link (RL) pilot is controlled by the quality feedback of a substantially continuous delay sensitive traffic stream, such as Voice-over-IP (VoIP), when such a stream is enabled. When such a stream is not enabled, the quality of a continuous RL overhead channel is used to control the pilot power. At the same time, the Traffic-to-Pilot Ratios (TPR) of contemporaneously transmitted delay sensitive data streams are independently adjusted based on a quality feedback associated with each such data stream.Type: GrantFiled: January 13, 2006Date of Patent: April 7, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Suman Das, Pantelis Monogioudis, Shirish Nagaraj, Subramanian Vasudevan, Harish Viswanathan, Jialin Zou

Patent number: 7489674Abstract: A method for wireless LAN communication using multiple channels is provided. An ATIM containing channel information is generated when there is data to be sent, and the ATIM is transmitted via a main channel after a predetermined period of time. When a station loses a channel reservation competition, the station generates and transmits via the main channel another ATIM containing channel information regarding another channel to be used from data transmission. The station then performs channel switching to the other channel corresponding to the channel information, transmits the data via the other channel, and switches the channel back to the main channel at the time of a subsequent beacon.Type: GrantFiled: May 17, 2004Date of Patent: February 10, 2009Assignee: Samsung Electronics Co., Ltd.Inventor: Jun-whan Kim

Patent number: 7463731Abstract: A dual mode packet phone is provided, comprising a first connector to connect the phone with a data network, and a second connector to connect the phone with a backup network. The phone automatically switches between the data and backup networks in the event that the data network fails to process the call in a timely manner. In a preferred embodiment, the phone is a Voice-over-IP phone, and comprises a voice processing unit, a control unit, a line interface, a data network interface, and a backup switch.Type: GrantFiled: September 5, 2003Date of Patent: December 9, 2008Assignee: Siemens Communications, Inc.Inventors: William J. Beyda, Florin Gheorghiu

Patent number: 7411982Abstract: Simultaneous transmission of voice and data over the voice channel of a digital wireless communications network, such as a “cell phone” network, is reconfigurable on the fly among multiple operating modes, including a lull detection mode in which data is transferred during a lull or quiet period in the voice content. Additionally, control signaling in the voice channel, rather than over a separate control or “overhead” channel is employed to support SVD. The described system operates transparently over any wireless telecommunications system.Type: GrantFiled: July 31, 2007Date of Patent: August 12, 2008Assignee: Airbiquity Inc.Inventor: Philip Ray Smith

Patent number: 7397791Abstract: An improved telephone system over a single telephone line within a residence or other building is disclosed, supporting exchange features and enabling easy expansion for multiple external lines. The existing telephone wiring is used as the medium for a local data communication network carrying multiple voice channels. In each outlet, one or more voice channels are converted into a standard telephone-line interface. Life-line functionality is facilitated by using the lower band of the spectrum isolated from the data communication network, and a dedicated connector in the outlet provides access to this band. External telephone feeders are converted to digital form for interfacing to the in-home data communication network.Type: GrantFiled: January 3, 2005Date of Patent: July 8, 2008Assignee: SERCONET, Ltd.Inventor: Yehuda Binder

Publication number: 20080002672Abstract: A method and device for communicating multiple communications networks from a single chassis is disclosed. In an exemplary embodiment, the communication device includes a processing unit, a network interface, a service interface, an endpoint interface, and a cluster interface. The processing unit controls various data flows in the communication device. The network interface communicates to at least one other communications network. The endpoint interface provides communication to local end devices and between local systems. While the service interface is designated to enhance service capabilities, the cluster interface is devised to expand system capacity. In this embodiment, the processing unit, the network interface, the service interface, the endpoint interface, and the cluster interface are assembled in one unit.Type: ApplicationFiled: June 27, 2007Publication date: January 3, 2008Applicant: V2 Technology Inc.Inventor: Tzerng-Hong Lin

Patent number: 7283512Abstract: An illustrative intelligent network and method for providing voice telephony over ATM and point-to-multipoint connectivity are provided that can provide significant advantages. A method for providing a point-to-multipoint service to control point-to-multipoint connections using an intelligent network and a switched virtual circuit over an ATM network includes receiving a request from a calling party to establish a point-to-multipoint connection, determining if the calling party is authorized to make point-to-multipoint connections, rejecting the request if the calling party is not authorized to establish point-to-multipoint connections, analyzing the request to determine if the bandwidth requested for the point-to-multipoint connection is within authorized bandwidth limits, and rejecting the request if the bandwidth requested is not within authorized bandwidth limits. An intelligent network for providing VToA and point-to-multipoint connectivity is also provided.Type: GrantFiled: January 22, 2001Date of Patent: October 16, 2007Assignee: Verizon Business Global LLCInventor: Thomas Glenn Hall, Jr.
