Embodiments provide an area, cost, and power efficient multi-service transceiver architecture. The multi-service transceiver architecture simplifies receiver/transmitter front ends needed for a multi-service architecture, by replacing significant portions of multiple receiver and/or transmitter front ends with a single ADC and/or DAC, respectively. In embodiments, a plurality of received service contents are combined into one composite analog/RF signal and applied to an ADC. The ADC converts the composite signal into a composite multi-service digital signal. Digital techniques are then used to separate the plurality of service contents into a plurality of respective digital streams that each can be independently demodulated. Similarly, in the transmit direction, a plurality of digital streams, including a plurality of service contents, are combined into one composite digital signal. The composite digital signal is applied to a DAC to generate a composite multi-service analog/RF signal for subsequent transmission over a coaxial cable or wirelessly via an antenna.

A network of switches includes N input accesses and M output accesses, with each of the switches including four ports and with the network input and output accesses being connection switch ports. The network includes at least one stage of switches, with each stage including: a pair of switch lines whose ports are not used as network input or output accesses, referred to as “interconnection switches”, a line being a set of interconnection switches connected to one another; and at least two transverse arms linking interconnection switches of different lines, a transverse arm consisting of elements that are separate from those of the other transverse arms, a transverse arm including at least two links and a switch, referred to as “transverse switch” with the connection switches being transverse switches. At least two transverse switches from different transverse arms of each stage are connection switches of the network.

A space-based component, such as a satellite, is configured to receive wireless communications from radiotelephones in a satellite footprint over an uplink satellite radiotelephone frequency, and to transmit wireless communications to the radiotelephones over a downlink radiotelephone frequency. An ancillary terrestrial network, that may include one or more ancillary terrestrial components, is configured to transmit wireless communications to, and receive wireless communications from, the radiotelephones over the uplink satellite radiotelephone frequency in a time-division duplex mode. An interference reducer is configured to reduce interference from the wireless communications that are received by the space-based component from the second radiotelephone and/or from the ancillary terrestrial network over the uplink satellite radiotelephone frequency, using the wireless communications that are transmitted by the ancillary terrestrial to, and/or received by the ancillary terrestrial network from, the second radiotelephone over the uplink satellite radiotelephone frequency.
摘要:
A remote unit consisting of an enclosure, equipment providing network access, connections to a limited amount of subscribers and a central office which also provides exterior connectivity. Users and information sources in the vicinity of the remote unit can use a wired or wireless interface to the remote unit for content delivery to a central location.

A communication system includes a first storage section for storing a plurality of pieces of contents information, a second storage section for storing a plurality of pieces of contents information, a control section for accessing the contents information stored in the first storage section and the second storage section based on a single set of management information for managing the contents information stored in the first storage section and the second storage section, a communication section for interconnecting the first storage section, the second storage section and the control section for communication, and an accounting setting section for setting an amount of money to be imposed on a predetermined user in response to use of the first storage section or the second storage section.
摘要:
An information fulfillment system and method for providing information to a caller having a wireless communication device. Upon receipt of sensory prompting and manual or automatic input of access codes to the wireless communication device, the caller's identity and the input access code are verified. Thereafter, the call is connected through the PWN and along the PSTN to the system messaging or fulfillment center for automatic or live-operator delivery of the requested information. Automatic verification, connection, and billing modification processes are provided for implementation of the system and method.

摘要:
Systems and methods for notifying a user that a specified person is within a specified distance of a specified meeting location are disclosed. A method according to the invention includes receiving a location signal that represents a current location of a specified party, storing identity data that represents an identity of the specified party and location data that represents a specified location, and determining from the location signal and the location data whether the specified party has arrived at the specified location. Such a method can also include transmitting a notification message if the specified party has arrived at the specified location.
