Automated Wireless Network Design

View page
US Patent:
6539221, Mar 25, 2003
Filed:
Dec 28, 1999
Appl. No.:
09/473746
Inventors:
Mini Vasudevan - Richardson TX
Carlos Garcia - Allen TX
Chang Yu - Plano TX
Hakan Ernam - Wilmington MA
Will Egner - Allen TX
Sairam Subramanian - Dallas TX
Kenni Rasmussen - Holte, DK
Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
H04B 1700
US Classification:
455423, 455 671, 455453, 455424, 455425, 455449
Abstract:
The present invention is a system for optimizing an existing wireless network and additions to an existing network. The system determines a value representing estimation of traffic in discrete bins within a geographic area. The traffic estimation includes a distribution of handover and new cell traffic based at least in part on the presence of a road in any bin or the proximity of a bin to a handover boundary. The cell coverage and carrier allocations of existing cells are adjusted in view of the traffic estimation.

Distributed Signaling Message Routing In A Scalable Wireless Communication System

US Patent:
6553227, Apr 22, 2003
Filed:
Jul 17, 2000
Appl. No.:
09/617448
Inventors:
Joseph S. M. Ho - Dallas TX
Nhut Nguyen - Richardson TX
Hakan Ernam - Plano TX
Assignee:
Nortel Networks LTD - St. Laurent
International Classification:
H04Q 720
US Classification:
455433, 455560, 455445, 455453
Abstract:
A wireless communication system constructed according to the present invention assigns each serviced mobile unit to a serving mobile switching center to minimize mobility management overhead and to equalize loading among a plurality of mobile switching centers. The wireless communication system includes the plurality of mobile switching centers and a base station system which includes a plurality of base station controllers, each of which couples to a plurality of base stations. A plurality of mobile units served by the system are assigned to the mobile switching centers so that loading is equalized. In one particular construction of the wireless communication system, a dispatching switch couples the base station system to the plurality of mobile switching centers and performs the assignments of the mobile units. In an example of operation, upon attachment of a mobile unit, the dispatching switch determines loading of each of the mobile switching centers. Then, based upon the loading, the dispatching switch assigns the mobile unit to one of the mobile switching centers, the âservingâ mobile switching center.

US Patent:
61482013, Nov 14, 2000
Filed:
Jul 31, 1998
Appl. No.:
9/127104
Inventors:
Hakan Ernam - Dallas TX

US Patent:
60979518, Aug 1, 2000
Filed:
Aug 6, 1998
Appl. No.:
9/130293
Inventors:
Hakan Ernam - Plano TX
Jim Xu - Plano TX
Christopher S. Reece - Plano TX
Assignee:
Northern Telecom Limited - Montreal
International Classification:
H04Q 720
US Classification:
455433
Abstract:
A method and apparatus for scaling a wireless telecommunications network having an architecture based upon subscriber distribution includes providing a base station subsystem (BSS) and a pool of mobile switching centers (MSCs) interconnected with one another. The mobile switching centers include visitor location registers (VLRs). Lastly, a dispatcher mobile switching center (DMSC) is provided, the dispatcher mobile switching center being coupled between the base station subsystem (BSS) and the pool of mobile switching centers (MSCs) for establishing communication between the base station subsystem (BSS) and the pool of mobile switching centers (MSCs). The dispatcher mobile switching center (DMSC) further provides for distributing mobile station subscribers and call related work among the pool of mobile switching centers (MSCs).
