Patent Details: US 6,628,629 B1

Title: Reservation based prioritization method for wireless transmission of latency and jitter sensitive IP-flows in a wireless point to multi-point transmission system

Assignee: Malibu Networks Inc.

Inventor: Jacob W. Jorgensen

Filing Date: July 9, 1999

Issue Date: September 30, 2003

Abstract:
The invention describes a method for managing data traffic in a wireless network. It uses an "advanced reservation algorithm" to prioritize and schedule the transmission of data packets, especially those sensitive to delays and variations in delay (jitter). This system aims to improve the quality of service (QoS) for various types of data, such as voice and video, transmitted over a wireless connection.

Plain-Language Summary of Independent Claims:

• Claim 1: This claim outlines a method for assigning future time slots in a transmission frame for data packets in a wireless network. The core of this method is an "advanced reservation algorithm" that reserves a first slot for the initial data packet of an internet protocol (IP) flow and then reserves a second slot in a subsequent frame. This ensures that the second packet is placed in a way that maintains a consistent, or "isochronous," timing with the first, which is crucial for applications like voice and video.
• Claim 14: This claim describes a system for assigning these future time slots. It includes components for applying the "advanced reservation algorithm," reserving a first slot for an initial data packet, and then reserving a second slot in a later frame to maintain a consistent timing for the data flow.
• Claim 26: This claim focuses on a machine-readable medium (like a computer disk) that contains instructions for a processor. When executed, these instructions cause the processor to perform the method described in claim 1. This essentially covers the software or firmware that would implement the patented process.
• Claim 38: This claim details a method for providing isochronous (time-sensitive) data packets in a telecommunications system. This system includes a wireless base station, host workstations, and subscriber equipment. The key element is the use of an "advanced reservation algorithm" to reserve time slots in future transmission frames, ensuring a steady and predictable flow of data.
• • Claim 50: This claim describes a system that provides isochronous data packets within a telecommunications network. This system includes a wireless base station, host workstations, and subscriber equipment, along with a means for allocating bandwidth. The system uses an "advanced reservation algorithm" to reserve slots in future transmission frames in a time-synchronized manner.

Litigation Status:

A search of the U.S. Court of Appeals for the Federal Circuit (CAFC) dockets for the year 2026 reveals no cases involving US Patent 6,628,629. However, historical records indicate a PTAB (Patent Trial and Appeal Board) case, IPR2018-00727, which resulted in a settlement. There was also a case filed in the Texas Eastern District Court (2:17-cv-00577).

Note: The legal status of this patent is listed as "Expired - Lifetime" as of the current date.
