Method and apparatus for providing voice assisted call management in a telecommunications network

This invention provides a novel switch for use in a telecommunications network that is capable of interacting with a voice assisted services server, such as a voice activated dialing (VAD) server. The switch is configured to set-up a calling session between an originating terminal and the VAD server that creates a voice connection between the user at the originating terminal and the VAD server, the voice connection passing through the switch. The VAD server can then in response to a spoken utterance indicative of the party the user wishes to call, generate a transcription of the utterance and extract from a database the telephone number associated with this transcription. The VAD server then formulates a call session redirect message in which is embedded the telephone number of the party the user wishes to call. This call session redirect message is received by the switch and the command implemented such that the call session is redirected toward the desired location. After this procedure is completed, the connection between the switch and the VAD is released. The invention also extends to a novel voice assisted services server capable of remotely effecting call management at a switch based on a spoken utterance conveyed to the voice assisted services server over a voice connection. Further, the invention also extends to methods for operating a switch and a voice assisted services server to implement the above described functionalities. Yet, the invention also extends to a novel method and apparatus to effect billing operations allowing to differentiate for a single call session the part of the call session involving the voice assisted services server and the part following the call session redirect event.

Transmission of urgent messages in telemetry system

A radio transmission system including many radio transmitters using frequency hopping carriers to intermittently transmit very short messages indicative of status of stimuli associated with the transmitters. The transmitters transmit transmissions independently of a receiver receiving the transmissions and independent of each other. In operation, radio transmitters transmit messages at varying frequencies at time intervals that can be varied as well. The frequency and time intervals are varied according to patterns that can be determined individually for each transmitter. A receiver holds data indicative of the future transmission frequency and time for each transmitter and updates the data based on the time and the content of the received messages. In addition, a simple method is provided to generate a very large number of orthogonal frequency-time hopping sequences that are individual for each transmitter and based on the transmitter ID. The problem of transmission of urgent messages is solved by transmitting urgent transmissions at transmission opportunities having precise time and frequencies that, advantageously, are in relations with the routine transmissions. The problem of power-up synchronization in such system is solved by rapidly transmitting, at transmission opportunities, a sequence of synchronization transmissions that carry information about the time and the frequency of a future routine transmission.

A telemetry system includes many radio transmitters using frequency hopping carriers to intermittently transmit transmissions indicative of status of sensors associated with the transmitters. The transmitters transmit transmissions independently of a receiver receiving the transmissions and independently of each other. The carrier frequency and the time between transmissions are changed according to a frequency-time hopping sequence that is different for each transmitter. The sequences and the resulting frequency ad time hopping are predictable and can be reproduced in the receiver based on the transmitter ID number. The system also includes one or more receivers containing a plurality of memory registers to hold, simultaneously for each transmitter, digital data indicative of (a) expected time and (b) expected frequency of the next transmission occurrence. The data is updated based on the time and the content of the received transmissions. The receiver authenticates the received transmissions by discriminating transmissions received at a wrong frequency and time. In addition, each transmitter encrypts the transmission using a variable encryption key that is varied with each transmission. The key variations are based on the frequency and time hopping sequence and are different for each transmitter. Alternatively, prior to encryption, each transmitter modifies data for transmission, using a modifier that is varied based on the frequency and time hopping sequence that is different for each transmitter. In addition, for faster acquisition and robust operation, the receiver includes and RSSI circuit based on FFT to detect transmitted carrier power at several different frequencies. The receiver also includes one or more frequency selective circuits that are tuned in response to the outputs from FFT and the status of the time and frequency registers.
