A CATV head end, terminal unit, and system permits time reservation of selected programs by the simple process of entering a program number at the terminal unit. At the head end selected programs are transmitted via cable to the terminal units and include a timer start command located at the start of a program, and a timer end command located at the end of a program. The commands identify the program by a program number, and the start command also identifies the channel on which the program is t...
A method of collapsing a communication path among at least two communication units (104-107) reduces the number of sites normally required to provide a communication. Each of a plurality of site controllers (103) in a radio communications system has a corresponding coverage area (100, 101), and at least some of the coverage areas (710-712) overlap one another. The method includes the step of determining (402) whether the communication units are currently being serviced by different sites, and th...
A dual or multi mode telephone can be connected to at least one cellular network or at least one cordless network. The telephone continuously monitors system information messages from said at least one cellular network and said at least one cordless network to maintain an idle mode connection. The telephone comprises first memory means for storing cell identification information about the cell in the cellular network concerned covering the telephone, and second memory means for storing cell iden...
A base station power control for dynamically introducing transmission power to compensate for rain fade in a broadband wireless system operating at millimeter wave frequencies. The base station periodically polls a selected network interface unit at a customer site to obtain status information such as the power level of the received signal. Variations in the power level of the received signal, indicative of variations in the attenuation of the wireless link, are used by the base station power co...
A system for establishing a telephone connection to a portable telephone in a telephone system, comprises a telephone line connected to a base station, a plurality portable telephones each connectable to telephone line via the base station. The base station monitors the telephone line and outputs a trigger signal when it detects ringing at the telephone line. The trigger signal comprises an address or an ID for the address which addresses at least a group of the plurality of telephones whereby t...
A method and apparatus is provided for notifying a subscriber via a telephone calling card that a message has arrived at the message center of a service subscriber. The messaging center may be a voice mail or e-mail system. In accordance with the method, the service provider receives and stores an incoming message for the subscriber. The service provider then transmits a radio signal to the telephone calling card of the subscriber indicating that the incoming message has arrived.
The invention provides a method for "adjusting" an identified or measured time-of-arrival of the first-arriving component of an incoming to more accurately reflect the time-of-arrival of the line-of-sight component of the incoming signal by reducing the so-called time-shift due to multipathing. In accordance with the principles of the present invention, the adjustment to the identified time-of-arrival of the first-arriving component is based on at least one parameter of an RF model that characte...
A peak power regulator is disclosed that functions within a Code Division Multiple Access (CDMA) transmitter to reduce peak power spikes within baseband signals while maintaining the average output power consistent with the average input power, controlling the out-of-band emissions, and maintaining the in-band signal quality within an acceptable degradation. In-phase and quadrature baseband signals are input to a delay block and an envelope magnitude predictor within the peak power regulator. Th...
A mobile phone uses a subscriber identification card which includes memory used by the mobile phone as external auxiliary memory. The mobile phone itself includes memory and can transfer data from the card's memory to the phone's memory. The card executes commands for updating data contained in the card's memory which is transmitted by short mobile phone messages to the mobile phone and eliminates the commands contained in the short messages after they are executed. The mobile phone can detect i...
To set up a telecommunication link to a person who is in a substantially enclosed facility such as an airplane, inside which there are several internal communication transmitting terminals operated by a private branch exchange of the facility, a personal call number is assigned to a private telecommunication transmitting terminal of the person in a public telecommunication network at least during the person's stay in the facility, the assignment is stored of his/her personal call number to the i...
