Abstract: A method for storing and retrieving telemetry which can reduce the size of a data storage tape and the time for retrieving data by overcoming the problems in a conventional satellite control system wherein all telemetry received from a satellite are stored without being subject to a filtering operation in a hard disk or memory of a computer for a predetermined time, and when needs arise for replaying previously stored data, a tape which stores required data is first located and mounted on a driver in order to load the required data. In accordance with the method of the present invention, data is filtered with respect to a variation of each telemetry. The data is stored step by step according to the period for which data should be stored. The data which should be stored for a long term is compressed and stored as an average value, maximum value, minimum value and variance of daily data. The generation and storage of long term data are offline processed.

Abstract: Allowing a separate system owned by a service provider to access telephone terminals of consumers to determine the calling patterns of each consumer, utilize service plan information of different network carriers, automatically change the network carriers used by an individual consumer to more closely match the calling patterns of the consumer and the plan incentives, and to store information in the telephone terminal so that calling information is provided to the individual consumer in accordance with the service plan of the selected network carrier. The information stored in the telephone terminal of the consumer causes that telephone terminal to alert the consumer to special times during which the consumer should make telephone calls. In addition, the telephone terminal will warn the consumer upon the consumer attempting to place a call if there is a more advantageous time to place the call within some predefined time period.

The user can directly record the telephone conversation while he or she is on the phone, and record a voice message to be transmitted to the family when he or she goes out. The user can call the family in the house using the indoor broadcasting function. It is possible to rapidly effectively clean the polluted air and the various smell generated in the kitchen.

Abstract: A data collection method and system is provided, by which blank time due to a time lag is not generated and a call probability to be broadcast can be calculated based on the number of potentially calling terminals which was counted as recently as possible. In the method, the center broadcasts to terminals a call probability and a control ID number which is increased by one for each broadcast. Each terminal calls up the center based on the received probability value, and if calling up, the terminal informs the center of terminal data and the received ID number. The center manages the probability value and the number of received calls for each ID.

Abstract: The invention concerns a method for the implementation of charging in a telecommunications system including customer terminals used by customers for ordering services and servers for providing services to customers. In order to implement the charging of services easily especially in a multimedia environment, at least one separate billing server is used in the network so that each customer terminal has a dedicated billing server. A contract message is sent to the customer terminal stating that the customer must make a contract on the selected service, and the customer's acceptance of the contract is sent from the customer terminal to the billing server in the network. The billing servers of the network are used for transferring charging records to the billing system so that the transfer of the charging record(s) concerning the selected service involves at least one billing server.

Abstract: A method of providing direct communication between a pair of mobile stations over a single voice channel is disclosed, as well as a novel mobile station equipped with the capability to function in a so-called base-station-emulation (BSE) mode. A mobile switching center (MSC) first determines whether direct communication between two mobile stations is possible, by verifying that at least one of them can function in BSE mode. The MSC then establishes whether a clear radio link between the two mobile stations can be established and assigns a single voice channel for the conversation. In this way, the number of base station transceivers required to service a cell can be reduced. If the locations of the two mobile stations are known, feasibility of direct communication can be easily determined. Optionally, the MSC might order the two mobile stations to exchange modulated audio tones and report measured received signal strengths. Direct communication is then established subject to an evaluation by the MSC.

Abstract: A telecommunications system includes an access terminal coupled to subscriber lines, a local exchange carrier (LEC) network, and a channel unit card coupling the access terminal to the LEC network. The channel unit card includes a processor configured to convert call processing signals received from the LEC network and formatted according to a protocol used by the LEC network to a message-oriented signal whose format is independent of the protocol used by the LEC network. The message-oriented signal then can be delivered to the access terminal. The channel unit card processor is further configured to convert message-oriented signals representing call processing communications received from the access terminal and having a format independent of a protocol recognized by the LEC network to one or more signals formatted according to the protocol recognized by the LEC network. The signals converted to the format recognized by the LEC network then can be routed to the LEC network.

Abstract: In a mobile communication system of this embodiment, when a terminal device starts communications using a system that does not register the terminal device, it transmits a temporary use registration request to an exchange apparatus after it confirms based on message information from the exchange apparatus that use registration is permitted. Upon reception of the temporary use registration request, the exchange apparatus authenticates the request source terminal device, and thereafter, supplies the terminal identification number of the own system to the terminal device. In addition, the exchange apparatus stores the supplied terminal identification number in correspondence with the home terminal identification number of the request source terminal device, so as to process incoming/outgoing traffic or calls associated with the terminal device on the basis of the stored information.

Abstract: A computer integrated telephony system embodied in a PC that includes a telephony interface connected to the local loop that detects whether one or more extension phones are off-hook by using the signal generating and detection capabilities found on a typical telephony interface card. In the preferred embodiment, the telephony interface is based on a programmable DSP that generates and injects onto the local loop a subsonic signal having a known shape and amplitude. If one or more extensions are off-hook, the amplitude of the subsonic signal detected on the line will be significantly attenuated. The amplitude of the detected signal is compared against a threshold value and an indication is made if the detected signal amplitude is below the threshold value.

Abstract: A micro-diverse directional antenna array positioned proximately upon the boundary of a convex shape whereby the primary attenuation lobes of neighboring antennae overlap. This creates a situation in which the reception of signals by said array from the space-time-delay domain of transmission can be effectively modeled as a banded linear transformation upon discretized space-time-delay domain of transmission yielding the antenna reception at discrete time steps.

Abstract: An external adapter circuitry is plugged into the printer port of a host computer to provide the utility of computer telephony for the host computer. The circuitry is housed in a compact box which is about the size of a common parallel port connector. The circuitry consists of a telephone line interface for receiving and sending signals from/to the telephone line; a printer port interface for sending data to and receiving data from the host computer; a couple of registers for latching signal-in and signal-out; a A/D converter for converting analog signals to digital signals; and a D/A converter for converting digitized signals to analog signals. More specially, the electricity of the entire circuitry is supplied from a signal-to-power converter which obtains voltages from the printer port. Therefore, the external adapter circuitry does not need a power line for external power supply.
