Appl. No.:

09/568687

Inventors:

Jie Chen - Bridgewater NJ, US
Jit Kumar - Basking Ridge NJ, US

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

G06F 15/16

US Classification:

709250, 709230, 709236, 709245

Abstract:

A system for, and method of, selectively detaching point-to-point protocol header information from a packet received from a network and a network adapter incorporating the system or the method. In one embodiment, the system includes: (1) a sub-protocol detector that receives the packet and identifies therefrom a sub-protocol employed with respect to the packet and (2) a header detacher, coupled to the sub-protocol detector, that detaches at least some of the point-to-point protocol header information from the packet based on an identity of the sub-protocol thereby to reduce an overall size of the packet.

US Classification:

379351

Abstract:

A DTMF digit detecting method and apparatus includes signal state identifier (32) for identifying whether the received signal is in a DTMF-digit-detect state, a no-detect high-energy state, or a no-detect low-energy state, digit candidate identification processor (34) for identifying a digit candidate when the presence of a state other than the no-detect low-energy state is detected following a detection of the presence of the no-detect low-energy state for a first predetermined period of time, digit identifier (32) for identifying a DTMF digit corresponding to a sample group in a DTMF-digit-detect state, and valid digit identifier (34) for identifying a valid DTMF digit when at least a first predetermined number of sample groups are all in the DTMF-digit-detect state or in an allowable combination of states. An allowable combination of states exists provided the following conditions are met: (1) at least half of the first predetermined number of sample groups are in the DTMF-digit-detect state and correspond to the same DTMF digit; (2) no two sequential sample groups are in a state other than the DTMF-digit-detect state; and (3) no two sequential sample groups in the DTMF-digit-detect state correspond to one or more DTMF digits other than the DTMF digit corresponding to at least half of the first predetermined number of sample groups.

Abstract:

The technologies described herein are generally directed to facilitating operation of a system for implementing fifth generation (5G) or other next generation networks. In accordance with one or more embodiments, a method described herein can include identifying, by a device comprising a processor, predicted resource usage of a first antenna covering a geographic zone. Further, the method can include selecting, by the device, a group of geographic siting locations within the geographic zone for potentially siting ones of a group of second antennas. In addition, selecting, by the device, a spatial arrangement in relation to the first antenna, of a subset of the group of geographic siting locations can occur, with a selected spatial arrangement including an arrangement to maintain the predicted resource usage in the condition.

G01S 5/10

Abstract:

Techniques for locating a mobile device using a time distance of arrival (TDOA) method with disturbance scrutiny are provided. In an aspect, for respective combinations of three base station devices of a number of base station devices greater than or equal to three, intersections in hyperbolic curves, generated using a closed form function with input values based on differences of distances from the device to pairs of base station devices of the respective combinations of three base station devices, are determined. The intersection points are then tested for robustness against measurement errors associated with the input values and a subset of the intersection points that are associated with a degree of resistance to the measurement errors are selected to estimate a location of the device.

International Classification:

G06F 21/55
G06F 21/85

Abstract:

A system detects a covert timing channel on a combinational structure or a memory structure. The system identifies the events behind conflicts, and constructs an event train based on those events. For combinational structures, the system detects recurrent burst patterns in the event train. The system determines that a covert timing channel exists on the combinational structure if a recurrent burst pattern is detected. For memory structures, the system detects oscillatory patterns in the event train. The system determines that a covert timing channel exists on the memory structure if an oscillatory pattern is detected.
