A cellular system comprising at least one moving non-stationary base station for enabling cellular communication between at least two mobile stations in a geographic area that lacks adequate cellular coverage by at least one stationary base station.

Moving cellular communication system

In a mobile communication system including a network having at least one base station operative to receive information in resource allocation terminology understandable to the base station and to allocate downlink bandwidth accordingly, at least one relay operative to convey to the base station information regarding needs of mobile communicators associated with the relay, using the resource allocation terminology understandable to the base station, and when receiving uplink bandwidth, from the base station, which generates an uplink between itself and the base station, to distribute the uplink bandwidth between the mobile communicators associated with the relay.

Various traffic management methods for dynamic multi-hop backhauling cellular network and systems useful in conjunction therewith

A method for repetition of uplink transmissions comprises: a repeater apparatus, aka uplink repeater, has a controller, a downlink receiver and an uplink transmitter and receiver. Use the downlink receiver to receive a downlink signal from a base station whose cell the uplink repeater is serving. For downlink frame(s) thus received: the controller demodulates at least a portion of the downlink frame and extracts MAP_D data describing allocation of an uplink transmission in upcoming uplink frame(s) to be transmitted after the downlink frame; controller determines a subset of UL transmission allocations to be repeated, to define a subset of mobile stations in the cell, whose uplink transmissions are to be repeated; the uplink receiver receives the UL transmissions to be repeated from each mobile station, and repeats the UL transmissions to be repeated by commanding the UL transmitter to send the content.

Partial uplink repeater system, method and computer program product

System for ex post facto upgrading of at least one Legacy personal communication device including a legacy modem and lacking at least one desired wireless communication feature, the system comprising an up-graded communication device including an auxiliary modem physically connected via an ex post facto physical connection to a Legacy personal communication device having at least one legacy wireless output channel which has been neutralized or disabled.

Add-on modem for wireless devices and methods useful in conjunction therewith

For use with a cellular communication network having a base station transmitting downlink signals received by mobile device/s: a downlink signal reception enhancement system including partial repeater apparatus enhancing quality of reception of at least a portion of downlink signal/s by mobile device/s, the partial repeater apparatus including a downlink receiver receiving at least a portion of downlink signal/s arriving from the base station; a controller including a critical region selector, selecting only a portion of at least one individual downlink signal; and a partial transmitter generating signal/s by regenerating, according to characteristic/s of at least one of a downlink signal and the mobile device, at least the portion selected by the critical region selector, and to transmit a signal including at least the regenerated portion plus less than all of the individual downlink signal.

Partial downlink repeater apparatus and methods useful in conjunction therewith

A moving cellular communication system comprising at least one upgraded moving relay including at least two base station functionalities and at least one mobile station functionality and a relay resource manager, all co-located, wherein each base station functionality from among the at least two base station functionalities of the upgraded moving relay is operative to communicate via antennae with at least one mobile station thereby to define a first radio link therebetween, and wherein each base station functionality has a connection to its co-located relay resource manager, wherein each mobile station functionality of the upgraded moving relay communicates via antennae with a unit which has base station functionality thereby to define at least one second radio link, respectively, wherein the relay resource manager in each individual moving relay comprises a radio resource manager; and functionality for exchanging information with relay resource managers is included in moving relays other than the individual moving relay.

Cellular communication system utilizing upgraded moving relays and methods useful in conjunction therewith

A cellular system that includes one or more moving relays, each having one or more add-on Interference Cancellation Modules (ICMs) capable of generating a cleaner signal by increasing the Signal-to-Interferer Ratio (SIR), thereby cancelling interference. The interference originates from intra-network or from out-of-network source. The system enables cellular communication between two or more mobile stations, in a geographic area that lacks adequate cellular coverage by one or more stationary base station.

A mobile communication system including at least one individual mobile communicator in a population of mobile communicators served by a plurality of nodes, including at least one base station; wherein at least one individual mobile communicator is operative to at least once associating itself with a serving node from among the plurality of nodes using a serving node selection functionality operative for selecting the serving node so as to increase use of available bandwidth to and from at least one node which provides the individual communicator with an acceptable signal to noise ratio.

Handover initiation methods and systems for improvement of cellular network performance

A cellular device architecture, including two application processors connectible through a Modem-AP Switch to two modems, each communicating with a respective antenna. A Controller module coupled to the switch and being configured, in response to receipt of data received in the Modem-AP switch as received through an antenna, to command the switch to select a processing route, whereby one of the application processors is switched to connect to one of the modems and to its associated antenna.

Switched application processor apparatus for cellular devices

A communication system comprising at least one communication network node having a capacity for communicating with at least one additional communication network node at a given center frequency; and at least one external frequency converter, external to said node, operative to cause at least one communication network node, from outside said node, to communicate with at least one additional communication network node, at least on occasion, according to a given communication protocol, at at least one converted center frequency which differs from the given center frequency, and also comprising beacon functionality.
