Abstract: In one embodiment, the method includes determining, at a first network element, whether to turn on compression of a header for a packet transport protocol used for a communication flow between the first network element and a second network element. The determining is based on a type of the communication flow, and the packet transport protocol is a protocol for transport of packets between the first and second network elements. The method further includes sending a compression mode indictor to the second network element along with a context identifier. The compression mode indicator indicates the determination, and the context identifier for use in identifying the communication flow.

Abstract: Apparatus and method are provided for detecting vehicles which are moving through a predetermined zone. The apparatus includes a plurality of acousto-electric transducers trained on the zone. A bandpass filter is provided for processing electrical signals from the plurality of acousto-electric transducers. A correlator having at least two inputs and an output is provided for correlating filtered versions of the electrical signals originating from at least two of the plurality of acousto-electric transducers. An integrator is provided for integrating the output of the correlator means over time. Finally, a comparator is provided for indicating detection of a vehicle when the integrated output exceeds a predetermined threshold.

Abstract: The performance of a wireless telecommunications system is enhanced by the exchange of frame error rate (FER) setting data between base stations and an FER control system within a selection/distribution unit. This exchange occurs when radio facilities from other base stations are added to a call during a soft handoff procedure.

Abstract: A method and apparatus for acoustically monitoring a highway is disclosed which is inexpensive to maintain and install and does not require that the roadway be closed, torn-up or repaved. These results are obtained in an illustrative embodiment of the present invention which comprises a Mill's Cross acoustic array mounted proximate to a highway, spatial discrimination circuitry, frequency discrimination circuitry and interface circuitry that generates a binary signal which indicates when a motor vehicle is, or is not, within a detection zone on the roadway.
