Patent number: 7899034Abstract: A plurality of base station devices are linked together and synchronized to facilitate communication between the respective base station devices and respective downlink subscriber stations. According to one embodiment of the invention, one of the base station devices is designated as a master device, and the other base station devices are designated as slave devices. The respective base station devices are connected to each other by means of a synchronization bus.

Patent number: 7796650Abstract: A direct way to measure network delay of a packet switched network uses a ping signal injected into the voice stream at a source telephone. The ping signal travels together with the voice stream to a destination telephone. The destination telephone detects the ping signal and returns it to the source telephone through the packet switched network. The source telephone detects the return ping signal sent by the destination telephone and calculates the network delay between the two telephones based on the difference between the time of transmitting the ping signal and the time of detecting the return ping signal. As the ping signal travels in the same path as the voice stream, the network delay between the two telephones is calculated directly and accurately.Type: GrantFiled: March 10, 2006Date of Patent: September 14, 2010Assignee: Acterna LLCInventors: David John Boyes, Jason Lee Davis, Bill Michael Kowalkowski

Patent number: 7792935Abstract: An IP-based group communication feature in a mobile communication network is based on the pre-established logical connections established between a gateway node (GGSN) and members of a group in the mobile communication network. No separate call establishment procedures using VoIP signaling are used for connecting a user equipment (UE) logically to group(s), but the procedure is preferably based on the normal logical connection establishment signaling (e.g. PDP context creation) as used for data service. The UE implements a host supporting the IP multicasting, and the next IP layer peer for the UE host is located in the gateway node. The gateway node provides an IP interface towards an external multicast router so that the UE host looks like a normal IP host supporting IP multicasting. The IP-based voice traffic is mapped and transferred over pre-established connections between the gateway and the UEs of the specific group.Type: GrantFiled: December 13, 2001Date of Patent: September 7, 2010Assignee: Nokia CorporationInventor: Juha Karjanlahti

Patent number: 7684324Abstract: The present invention provides a system and method for prioritizing delay-sensitive packets relative to each other for transmission from a router in a network, based on a delay variation estimated for each delay-sensitive packet by a quality of service monitor. In accordance with the present invention, late delay-sensitive packets are assigned a higher priority than, and are transmitted before, other delay-sensitive packets, thereby reducing the level of jitter and improving the quality of the packet streams that comprise late delay-sensitive packets.Type: GrantFiled: December 20, 2005Date of Patent: March 23, 2010Assignee: Telchemy, Inc.Inventor: Alan D. Clark

Patent number: 7672661Abstract: A management server includes a determination unit and a notification unit. The determination unit determines a communication network to which a mobile terminal connectable to a plurality of the communication networks by one telephone number is connecting. The notification unit issues a notice on the communication network connecting to the mobile terminal based on a result of the determination by the determination unit.Type: GrantFiled: October 21, 2005Date of Patent: March 2, 2010Assignee: NTT DoCoMo, Inc.Inventors: Motoharu Miyake, Hiroshi Inamura, Takashi Yoshikawa

Patent number: 7668200Abstract: The present invention provides a method for controlling transmission latency in a communications system, wherein the communications system is subject to a noise signal having at least a first noise phase and a second noise phase. The method includes determining a first bit rate for symbols transmitted during the first noise phase, and a second bit rate for symbols transmitted during the second noise phase, the first bit rate and the second bit rate being constrained such that a transmission latency does not exceed a pre-determined maximum allowed transmission latency; and transmitting symbols at the first bit rate during the first noise phase and at the second bit rate during the second noise phase. In other variants, the invention provides an apparatus, a constrained rate receiver, a transmitter and a signal.Type: GrantFiled: June 30, 2004Date of Patent: February 23, 2010Assignee: Broadcom CorporationInventors: Richard Greenfield, Miguel Peeters

Patent number: 7656904Abstract: In conjunction with a data communication network carrying multiple telephony signals and allowing for connection of telephone sets, a system and method in which two external feeders connect to the data network at two distinct points via two distinct devices. The data network can be based on dedicated wiring or can use existing in-premises medium such as telephone, powerlines or CATV wiring. In the latter case, the wiring can still carry the original service for which it was installed. The external telephone connections can be based on the traditional PSTN, CATV network, cellular telephone network or any other telephone service provider network, using specific adapter for any medium used. In the case of connection to a POTS telephone signal, VoIP gateway (or any other converter) is required.Type: GrantFiled: February 22, 2007Date of Patent: February 2, 2010Assignee: Mosaid Technologies IncorporatedInventor: Yehuda Binder

Patent number: 7633931Abstract: A method for dynamically handling the data path of a wireless IP phone is provided. The method comprises establishing a first communication link between the wireless IP phone and a wireless local area network (WLAN), establishing a second communication link between the wireless IP phone and a general packet radio service (GPRS) network, establishing a conversation session between the wireless IP phone and a second IP phone via a voice over internet protocol (VoIP) through the first or second communication link, determining whether the data path of the conversation session passes through the first or the second communication link according to a signal strength of the first communication link, and exchanging a plurality of packets of the conversation session through the data path.Type: GrantFiled: May 15, 2006Date of Patent: December 15, 2009Assignee: Lite-On Technology CorporationInventor: Ruey-Yuan Tseng

Patent number: 7619995Abstract: Transcoders and mixers having reduced algorithmic delay and processing complexity. An improved mixer for signals having encoded speech parameters wherein the parameters obtained through decoding are used by a parameter estimator to improve the encoding by providing a parameter estimate for the mixed signal. In the case of pitch parameters, the mixer uses the principle of strong-pitch-domination. The mixing of wideband signals is simplified by performing mixing of individual lower and upper sub-bands. A transcoder and a mixer that converts a wideband signal into a narrowband signal relies upon high frequency suppression. A transcoder and a mixer that converts a narrowband signal into a wideband signal relies upon filter combination.Type: GrantFiled: July 15, 2004Date of Patent: November 17, 2009Assignee: Nortel Networks LimitedInventors: Mohamed Samy El-Hennawey, Rafik A.

Patent number: 7609646Abstract: A system in a Voice Over Internet Protocol (VOIP) network eliminates false voice detection in voice band data service (e.g., modem or facsimile transmission) by sequentially enabling silence detection then voice detection. In Voice Band Data (VBD) mode, the system initially enables silence detection and disables voice detection. If silence is detected in a VOIP signal associated with a VOIP call, the system enables voice detection. If voice is detected, the system switches from VBD mode to voice mode and enables processing (e.g., echo cancellation and/or data compression) that improves voice communications.Type: GrantFiled: April 14, 2004Date of Patent: October 27, 2009Assignee: Cisco Technology, Inc.Inventors: David Cheng-Song Qi, Yan Wang, Timothy G.
