Patent number: 7095866Abstract: A high frequency signal transmission apparatus includes a transmitter for transmitting received signals from a signal source as a modulated signal on a high frequency 900 MHz carrier to a remote receiver. The remote receiver converts the high frequency carrier in at least one conversion step to a lower frequency carrier signal. The lower frequency carrier signal carrying the modulated signal is then converted to an audio output or to another carrier signal and retransmitted as a modulated second signal to another remote receiver capable of demodulating the signal and broadcasting the audio sounds or video images. The oscillators in the transmitter and receiver are selectable to operate at discrete frequencies. Automatic fine tuning control is provided in the receiver to accommodate drift of the oscillator in the receiver.Type: GrantFiled: July 11, 2001Date of Patent: August 22, 2006Assignee: Akoo, Inc.Inventors: Niko Drakoulis, Ronald G.

Patent number: 7013129Abstract: Apparatus and a method for establishing a cellular mobile call. If no radio traffic (voice or data) channels are available for a calling Mobile Station (MS), then a test is made to determine the expected wait time before a channel becomes available. If the expected wait time is less than a first threshold, then the call request is queued. If a channel does not become available before a second time threshold, then the caller is notified that the call has been queued and is expected to be established in a short time. A control message is sent to the MS to trigger an indication of the queued status to the user. The indication may be one or more tones, a data display, or the playing of a pre-recorded announcement. If the expected wait time is more than the first threshold, the caller is given the opportunity to be called back when a radio channel becomes available. Advantageously, the number of failed calls because of unavailable traffic channels is reduced, and the caller's annoyance level is reduced.Type: GrantFiled: June 14, 2001Date of Patent: March 14, 2006Assignee: Lucent Technologies Inc.Inventors: Stephen C.

Patent number: 6882862Abstract: The present invention provides a system and method for using a standard private branch exchange (PBX), such as e.g., the Lucent Technologies, Inc. DEFINITY® PBX, for interfacing with a wireless (e.g., cellular, etc.) communication network and the public switched telephone network (PSTN). The system employs an adjunct controller and uses computer telephony integration (CTI) associated with a standard PBX to communicate directly with an audio switch and the PSTN. Through the use of CTI, the standard PBX also provides feedback to the caller. For example, when an inbound call arrives (i.e., from the PSTN to a radio transceiver), the adjunct controller determines whether the wireless system has available resources (i.e., an available link) to grant calls and instructs the PBX to provide an audio connection between dynamically assigned wireless links (e.g., RF channels). If no link is available, a busy signal is referred back to the PSTN, and eventually back to the originating switch.Type: GrantFiled: January 21, 2000Date of Patent: April 19, 2005Assignee: Avaya Technology Corp.Inventors: Shiann-An Chia, Ya-Tien Ko, Christopher Foard, William E.

Publication number: 20040192378Abstract: A remote telephone system for wireless telephony devices includes a remote server having communication control support to provide digital communication function control. Wireless telephony devices are grouped and the support is independently programmable for each group. The remote server further includes a data port connected to the communication control support for supporting a wireless data link to an individual wireless telephony device, and the remote server uses the data port to exchange programmed digital communication function control with the individual device. The data link to the control support gives the wireless device the functionality of a smart handset and bestows upon the group properties of an office exchange.Type: ApplicationFiled: March 25, 2003Publication date: September 30, 2004Applicant: COMVERSE, LTD.Inventor: Itzhak Wulkan

Patent number: 6785560Abstract: The instant invention discloses a method and system for providing a novel wireless centrex service that untethers subscribers from the immobility associated with traditional desktop telephones. Essentially, the present invention extends the benefits of wireless voice and data services to subscribers having a need to move within a plurality of localities such as business and hospital campuses. In accordance with the invention, a wireless telephone subscriber can use a standard cellular/PCS telephone as a wireless extension of their desktop phone, while in the proximity of a miniature radio base station capable of communicating with the PCS/cellular telephone. The advantage of such a system is that a subscriber can use the same cellular/PCS telephone that provides service in the public network in the wireless centrex environment. Additionally, the wireless centrex system provides services and features which are similar to those offered to regular centrex telephone subscribers.Type: GrantFiled: December 13, 1999Date of Patent: August 31, 2004Assignee: AT&T Corp.Inventors: Albert Chow, Jinman Kim, Hopeton Walker, Spencer Wang, Wenchu Ying

Patent number: 6775556Abstract: A system, device and method are provided for processing a call between a private exchange network and a mobile communication network in which a wireless trunk connection system or the like is used. A call is processed through the wireless trunk connection system in the private exchange network without passing through a public communication network when it is intended to establish a communication between an extension subscriber to the private exchange network and a subscriber to the mobile communication network. The wireless trunk connection system can have connections to a first mobile station for transmitting the destination telephone number dialed by the extension subscriber of the private exchange network to the mobile communication station through the first mobile station when the extension subscriber to the private exchange network requests communication services to the mobile communication network.Type: GrantFiled: May 24, 2000Date of Patent: August 10, 2004Assignee: LG Information & Communications, Ltd.Inventors: Gi Moo Ghoi, Hwan Jong Kang, Pill O Hong

Publication number: 20040121772Abstract: A method is for supporting mobility of a WLAN voice terminal which can guarantee mobility, when a data line such as an ISDN line is used as a communication line between a switching system and access points and when the WLAN voice terminal roams from a basic service set of one access point which it intends to be associated with to a basic service set of another access point during signaling. It also guarantees mobility when the WLAN voice terminal roams from a basic service set of one access point which it is currently associated with to a basic service set of another access point during an active call.Type: ApplicationFiled: December 12, 2003Publication date: June 24, 2004Inventor: Seon-Soo Rue

Patent number: 6745030Abstract: In a mobile communication system, when a mobile visitor terminal registered at a first network enters a second network, it sends a registration signal to a first exchange belonging to the second network. The first exchange sends a roaming start request signal to the first network. On receiving authentication information from the first network, the exchange writes it in a VLR (Visitor Location Register) storage. On the origination of a call on the visitor terminal, call information is written to a call information storage. A third exchange stores in an VLR holding node number storage the fact that the call information is stored in the first exchange. When the visitor terminal moves to the area of a second exchange, the second exchange sees, based on the content of the VLR holding node number storage, that the authentication information is stored in the first exchange, and obtains it. The second exchange switches connection thereto on the basis of the authentication information and call information.Type: GrantFiled: March 29, 2001Date of Patent: June 1, 2004Assignee: NEC CorporationInventor: Junichi Koyama
