Abstract: A method for regulating a call placement rate (CPR) of an autodialer (AD) (100) includes: measuring a time delay between a first event and a second event; and, adjusting the CPR of the AD (100) in response to the measured time delay.

Abstract: A switch-based feature that dynamically designates a class B line as class A if the call is a GETS call. The line remains class A until a non-GETS call is placed, whereupon the line reverts to its normal class B designation.

Abstract: A network entry switch based statistical authenticating entity validation scheme wherein the level of IEPS call validation by authenticating entity is dependent on network load and the level of failed validations for a given authenticating entity.

Abstract: A method is provided for routing an emergency call. The method comprises receiving an emergency call and identifying an end node associated with the call. The end node may be a communications device involved in establishing the emergency call that is geographically near the originator of the emergency call. A look-up table is then accessed to identify the appropriate public safety answering point (PSAP) associated with the end node, and the emergency call is routed to the identified PSAP.

Abstract: In a packet network, a feature wherein each node in the call path grants immediate admission to the network at a possibly reduced or even zero initial bandwidth. Additional bandwidth is incrementally allocated to the call as it becomes available until the maximum requested bandwidth has been allocated to the call for each node in the call path.

Abstract: A switch based feature that allows subscribers to adjust their incoming or outgoing audio signal strength. The value of the transmit or receive pad values on the subscriber line card are adjusted to control the strength of the audio signal transmitted to, or received from, the network. The subscriber controls the feature by sending a hook flash to the switch, entering the DTMF keypad feature code and transmit or receive volume parameters, and then returning to the call.

Abstract: A network entry switch based statistical authenticating entity validation scheme wherein the level of IEPS call validation by authenticating entity is dependent on network load and the level of failed validations for a given authenticating entity.

Abstract: An enhancement to AIN fault handling that allows SSP triggers to access an alternative treatment application when fault handling is invoked. If an alternative treatment application is referenced in the BCM fault handling attribute, then the application is called when AIN fault handling is invoked. If the alternative treatment application is not successful in completing the service function, then one of the traditional fault handling options is applied, (i.e., routing to a specific directory number, voice announcement then terminate call, continue, or final treatment). The present invention allows a last attempt at completing the service function by the alternative treatment application after fault handling is called, but before default handling or final treatment is invoked.

Abstract: An addition to AIN that allows SSP triggers to jump to internal SSP addresses for feature processing without a return. There is no query sent to an SCP nor the associated response message, call processing is not suspended, and there is no need for fault handling associated with the trigger.

Abstract: A system in which centralized announcement platforms are connected to host switches over dedicated trunks, and remote switches needing announcement services send a signaling message to a host switch requesting a connection to the announcement platform. A connection is then established between the host switch and the remote switch over a regular trunk, and the full connection is completed over a dedicated circuit between the host switch and the announcement platform. Announcement message ID and other information required by the announcement platform is coded in the available parameter fields of a signaling message. Less total circuits are required and redundancy is provided.

Abstract: Means and methods of producing catalytically coated microspheres of hydrocarbon fuel in a tower into which precharged free floating initially frozen globules of hydrocarbon fuel are drawn through a catalytic plasma field by an attracting electrostatic force disposed thereabove for catalytic coating and partial neutralization of the globule precharge until the coated globules descends in response to gravitational forces through the plasma field into a container disposed therebeneath.

Abstract: A catalyst/substrate delivery system providing a more efficient combustion of hydrocarbon fuels while reducing environmental pollutants emitting therefrom. A light hydrocarbon is misted into a cold environment to form frozen pellets which are then coated with plasma of an atomized catalyst such as platinum, palladium, lithium, zirconium organometals to form microspheres of from about 1 but less than 2000 microns in size.

Abstract: An improved cellular mobile radio telephone system is described wherein the switching matrices used to provide communication paths between subscribers is also used to provide paths for carrying control information between a network control and the various transceivers, receivers and transmitters at cell sites. Additionally, statistical multiplexers are provided at the cell sites for multiplexing control signals for many transceivers, receivers and transmitters onto the transmission facilities connecting the cell site with the network control system. At the network control system, apparatus is provided to reformat and packetize control signals from many statistical multiplexers and present the reformatted, packetized information to a network control processor.

Abstract: The locating function of a cellular mobile radio telephone system is implemented so that, when the locating radio detects a sustained change from a very low signal quality or amplitude (indicating background noise rather than an active call in an adjacent cell) to a higher quality or amplitude (indicating the start of a call in one of the adjacent cells), the radio will modify its filtering process so that previous sample values (which can be attributed, for example, to noise before the start of the call) will not be used in the averaging process. The result of this improvement is that values reported from the locating radio during the initial portion of the call (0 to 20 seconds) will not be reported artifically low. This allows the system to make decisions about handoff during this initial portion of the call. Additionally, rather than having the locating radio take equal samples from each of the possible voice channels, in accordance with the invention, there are two scanning tasks.

Abstract: In a cellular mobile radio-telephone system, a hand-off procedure is implemented by use of idle voice channel transceiver at relay stations of cells contiguous the site of a mobile station. The receiving portion of each transceiver is provided with tuning circuitry permitting a detuning from a preassigned idle channel frequency to the present broadcast frequency assignment of the mobile station. A set of measurements of broadcast signal is made at the detuned idle channels to determine the cell of best signal. The mobile station is then handed off to the cell of best signal.

Abstract: In a telephone system, particularly a mobile radio-telephone system, incorporating statistical multiplexers and control concentrators for the arranging and formatting of digitized data, the data is formatted with operational codes designating specific meaning and any one of a plurality of levels of protection to be offered data transmitted via the telephone system. A back-up memory is connected to the statistical multiplexer to enable a retransmission of a batch of data in the event that the batch had been received with error. Full duplex communication is provided. A circular sequence number interleaved among batches of the data is utilized by an error detector at a receiving site to determine the presence of all portions of a batch of data. Transmission of specified operational codes and additional data as required in the reverse direction commands a retransmission and also provides for acknowledgement of receipt of a data batch with and without error.
