Establishing A Session In A Packet-Switched Wireless Communications Network

US Patent:
7596115, Sep 29, 2009
Filed:
Sep 22, 2004
Appl. No.:
10/947656
Inventors:
Anit Lohtia - Plano TX, US
Brian D. Troup - Richardson TX, US
Yuqiang Tang - Plano TX, US
Assignee:
Nortel Networks Limited - St. Laurent, Quebec
International Classification:
H04W 4/00
H04W 72/00
US Classification:
370328, 370310, 370329, 4554351, 455450
Abstract:
A packet-switched wireless communications network includes a mobile station and a radio network controller that are able to establish a radio connection therebetween. Messages are exchanges over one or more traffic channels to establish a packet-switched services session between the mobile station and the radio network controller. The radio connection is not closed until all messages for establishing the packet-switched services session have been exchanged between the mobile station and the radio network controller.

Active Set Management Enhancement For Reliable Soft Handoff In 1Xev-Do System

US Patent:
7936720, May 3, 2011
Filed:
Apr 28, 2006
Appl. No.:
11/412959
Inventors:
Xixian Chen - Nepean, CA
Weigang Li - Nepean, CA
Vasanta Chivukula - Nepean, CA
Shiva Mirzaei-Rezaei - Kanata, CA
Brian Troup - Richardson TX, US
Miroslav Budic - Murphy TX, US
Yong Zhou - Kirkland, CA
Ryan Santa - Kanata, CA
Assignee:
Nortel Networks Limited - Mississauga, ON
International Classification:
H04W 4/00
US Classification:
370331
Abstract:
A method and system for connection management in a wireless data network, such as a 1xEV-DO network adds connections to new network sectors upon receipt of a connection request from an active terminal, but removes data connections that the active terminal requests to be dropped only after confirmation from the active terminal that a channel allocation message has been received and applied. The active network maintains an active set of connections that is at least as large as the active set maintained by the active terminal and does not initiate a connection termination if no confirmation of the channel allocation message is received. This allows for a reduction in the number of dropped connections.

Method And System For Reducing Connection Set-Up Time

US Patent:
8134963, Mar 13, 2012
Filed:
Apr 4, 2008
Appl. No.:
12/098073
Inventors:
Xixian Chen - Nepean, CA
Vasanta Chivukula - Nepean, CA
Weigang Li - Ottawa, CA
Guoqiang Xue - Kanata, CA
Ryan Santa - Kanata, CA
Miroslav Budic - Murphy TX, US
Brian Troup - Richardson TX, US
Martin Kendall - Wylie TX, US
Assignee:
Ericsson AB - Stockholm
International Classification:
H04Q 7/00
US Classification:
370329, 370338
Abstract:
A method of connection setup in mobile wireless data communications systems is disclosed where the connection setup time is decreased for delay-sensitive communications sessions relative to the normal connection setup time for confidence-dependent communications sessions. This is achieved by performing some of the connection set-up steps for delay-sensitive communications sessions after successfully demodulating a smaller number of indications identifying an access terminal's desired serving resource than would be demodulated in the case of a confidence-dependent communication session prior to performing the same connection set-up steps.

Establishing A Session In A Packet Switched Wireless Communications Network

US Patent:
2009031, Dec 17, 2009
Filed:
Aug 21, 2009
Appl. No.:
12/545374
Inventors:
Anit Lohtia - Plano TX, US
Brian D. Troup - Richardson TX, US
Yuqiang Tang - Plano TX, US
International Classification:
H04W 40/00
US Classification:

Abstract:
A packet-switched wireless communications network includes a mobile station and a radio network controller that are able to establish a radio connection therebetween. Messages are exchanges over one or more traffic channels to establish a packet-switched services session between the mobile station and the radio network controller.

Systems And Methods For Implementing Large Cdma Cell Sizes

US Patent:
6577616, Jun 10, 2003
Filed:
Dec 29, 1999
Appl. No.:
09/473712
Inventors:
Shahid Rasul Chaudry - Ottawa, CA
Muhammad Khaledul Islam - Nepean, CA
Hong Ren - Nepean, CA
Azeem Ahmad - Plano TX
Thomas Leonard Trevor Plestid - Ottawa, CA
Neil McGowan - Stittsville, CA
James Russell Weisert - Calgary, CA
Brian Douglas Troup - Garland TX
David Andrew Tetreau - Calgary, CA
David Allan Boettger - Singapore, SG
Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
H04B 7216
US Classification:
370342, 370331, 455561
Abstract:
Methods and apparatuses are provided for CDMA (code division multiple access) access availability to a large cell area, and for traffic channel establishment. A group of cell site modems are configured to look for access attempts generated in respective complete and/or sectorized circular or annular shaped areas centered at the center of the cell area, the areas collectively covering the cell area. To achieve this, each cell site modem has a local clock and the local clock within the first of the cell site modems is synchronized with a standard network time, and the local clock of each of the subsequent cell site modems is offset by a respective delay with respect to the standard network time which causes the cell site modem to search within its respective annular shaped area. A cell site modem is also made available as a traffic cell site modem and is operable to have its traffic acquisition search window centered at a location of an access attempt. Alternatively, a plurality of traffic cell site modems may be provided, each having dedicated circular or annular coverage areas within the cell.
