6628627, Sep 30, 2003

Filed:

Jul 9, 1998

Appl. No.:

09/112504

Inventors:

Allan M. Zendle - Oakton VA
David Ackerman - Washington DC

Assignee:

Winstar Communications Inc. - New York NY

International Classification:

H04B 700

US Classification:

370310, 370395

Abstract:

A multi-service subscriber radio unit includes an antenna and a transceiver which is operatively coupled to the antenna. The radio unit further includes a modem which is coupled to the transceiver and a packet control unit. The packet control unit provides multi-service packetized data for transmission (up-link) to the modem and receives multi-service packetized data from the modem (down-link). The packet control unit extracts service specific packetized data from the received multi-service packetized data and also generates the transmit multi-service packetized data from a plurality of service specific data from customer premise equipment. A plurality of service interface units are included which provide a suitable electrical interface between the customer premise equipment and the radio unit. A distribution control unit is interposed between the packet control unit and the plurality of service interface units. The distribution control unit directs service specific data to and from the service interface units.

International Classification:

H04B 700

US Classification:

455 381

Abstract:

A two-way communication system for communication between a system network and a mobile unit. The system network includes a plurality of base transmitters and base receivers included in the network. The base transmitters are divided into zonal assignments and broadcast in simulcast using multi-carrier modulation techniques. The system network controls the base transmitters to broadcast in simulcast during both systemwide and zonal time intervals. The system network dynamically alters zone boundaries to maximize information throughput. The system also uses a mobile unit which receives messages from the network and transmits messages to the network. The mobile unit includes a switch that allows a user to request the network to retransmit a received message that contains errors.

International Classification:

H04B 150

US Classification:

455 59

Abstract:

A two-way communication system for communication betweeen a system network and a mobile unit. The system network includes a plurality of base transmitters and base receivers include in the network. The base transmitters are divided into zonal assignments and broadcast in simulcast using multi-carrier modulation techniques. The system network controls the base transmitters to broadcast in suimulcast during both systemwide and zone boundaries to maximize information throughout. The preferred mobile unit inlcudes a noise detector circuit to prevent unwanted transmissions. The system network further provides an adaptive registration feature for mobile units which controls the registration operation by the mobile units to maximize information throughout.

Assignee:

Mobile Telecommunication Technologies - Jackson MS

International Classification:

H04M 1100

US Classification:

379 57

Abstract:

A system for establishing a communication link between a caller and a mobile communication device that includes a mobile telephone and a paging device capable of receiving information transmitted from a paging network. In addition to the mobile communication device, the system includes a telephone network, a first mobile switching center, a conference bridge, a paging network, and a second mobile switching center. The first mobile switching center receives a telephone call transmitted over the telephone network using an identification number of the mobile telephone. If the mobile communication device is not located in the area covered by the mobile switching center, the mobile switching center forwards the received telephone call to a conference bridge using a bridge number assigned to the mobile communication device. The conference bridge receives the forwarded telephone call and transmits an identification number of the paging device in the mobile communication device to the paging network. The paging network receives the paging number and transmits a page to the paging device using the paging number.
