Title: Methods and apparatus for controlling wireless network resources for data sessions based on ip address usage
Inventor: XUE HAO
IPC: H04L12/56
Filed: 2005-06-29
Abstract: One illustrative method of controlling wireless network resources for data sessions involves the steps of identifying IP address usage for mobile stations operating in a wireless communication network and causing a data inactivity timer of a data session for a mobile station to be set to an initial value that depends on the IP address usage. The data inactivity timer is set to a relatively large value when the IP address usag e is low, but to a relatively small value when the IP address usage is high in order to expeditiously release underutilized network resources. The data session may be Point-to-Point Protocol (PPP) session for which an IP address is dynamically-assigned to the mobile statio n.

Inventor: ROSE CONRAD
IPC: G01S3/46
Filed: 2004-07-16
Abstract: A method of and apparatus for passively determining agile-frequency-emitter location and computer-readable medium bearing instructions therefor. Unless a specified accuracy threshold is met or exceeded, phase, frequency, and baseline position are measured during a single receiver dwell and processed.  An array of gains and phase difference ambiguity integers for all phase difference measurements are computed. An emitter DOA unit vector or COS(AOA) is estimated and an LBI phase difference is predicted. If the rank of the set of baseline-frequency product differences is greater than 1, each DOA unit vector is projected and scaled by the measured frequency corresponding to the baseline measurement. Otherwise, if the rank is 1, the product of the COS(AOA) and baseline length is formed and scaled by the measured frequency. The corresponding ambiguous measured phase difference, resolved and differenced, is used to estimate the resulting integer value and the resolved phase change and emitter range is estimated from the angle change.
