Method And System For Reducing Call Setup By Roaming Number Caching

View page
US Patent:
6408181, Jun 18, 2002
Filed:
Feb 4, 1999
Appl. No.:
09/244923
Inventors:
Joseph S. M. Ho - Dallas TX
Jim Xu - Plano TX
Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
H04Q 720
US Classification:
455432, 455445, 455560
Abstract:
A method and system for improving overall system capacity in GSM networks by reducing the number of home location register and visitor location register queries is disclosed. The method and system allows the reuse of the MSRN by allocating the MSRN to a mobile terminal and using it for future calls. The method of the present invention allows the GMSC to cache the MSRN for a called mobile terminal. During a first call setup, an entry is recorded at a cache register that maps the Mobile Subscriber ISDN Number (MSISDN) of the mobile terminal to a previously allocated MSRN. Additionally, the Bearer Capability (BC) associated with this MSRN is also recorded in the cache register. When the next call arrives, the GMSC first checks if a MSRN for that called mobile terminal already exists in its cache register. If a cached MSRN is available and the BC associated with the cached MSRN matches the BC requested by the current call, then the GMSC uses the cached MSRN to route the call to the VMSC. The method and system of the present invention makes it unnecessary to query the HLR and VLR when a land-to-mobile call arrives thereby increasing network capacity while reducing processing load.

Method And Apparatus For Enhanced Call Setup

View page
US Patent:
63142929, Nov 6, 2001
Filed:
Aug 15, 1997
Appl. No.:
8/911628
Inventors:
Joseph S. M. Ho - Dallas TX
Jim Xu - Plano TX
Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
H04Q 720
US Classification:
455450
Abstract:
A method is illustrated for reducing the call setup time of high priority calls such as voice or high speed user generated data without unduly wasting RF frequency resources on non priority calls such as short message calls. This is accomplished by ascertaining the call priority at the base station controller (BSC) level in a GSM system soon after call initiation and immediately changing the channel assignment for use by the remaining signalling type messages to a different operational speed where appropriate. The concept is further extended by supplying the call priority data to a called party's BSC such that all signalling messages after initial contact can be at the operational speed appropriate to the priority of the call.

Method And Apparatus For Tracking Mobile Stations In A Wireless Communications System

View page
US Patent:
59436212, Aug 24, 1999
Filed:
Jul 24, 1997
Appl. No.:
8/923927
Inventors:
Joseph Ho - Dallas TX
Jim Xu - Plano TX
Assignee:
Northern Telecom Limited - Montreal
International Classification:
H04B 100
US Classification:
455456
Abstract:
A method and apparatus in a communications system for tracking mobile stations. The length and identify of the path of the mobile station is tracked at the mobile station. The path is monitored for a presence of a loop. In response in identifying the presence of a loop, the loop is removed from the path, wherein the length of the path is reduced. Additionally, the length of the path is compared to a threshold and a location update is performed in response to the length of the path being greater than the threshold. The threshold may also be updated at a MSC and then sent to the mobile station.

Method For Ordering Subscriber Records Of Wireless Communication Networks

View page
US Patent:
62244779, May 1, 2001
Filed:
Dec 28, 1998
Appl. No.:
9/221357
Inventors:
Joseph S. M. Ho - Dallas TX
Julie Y. C. Liu - Dallas TX
Jim Xu - Plano TX
Assignee:
Nortel Networks Limited - Montreal
International Classification:
H04O 720
US Classification:
453433
Abstract:
A method for ordering subscriber records in a location database stored in at least one of a Visitor Location Register (VLR) or a Home Location Register (HLR) of a wireless communications network by ordering the subscriber records in subsets according to the access rates of the records. Records within the respective subsets are then ordered in a middle-rootage order based on the subscriber ID of each subscriber record. The subscriber records are then inserted into a binary tree in subset order beginning with the subset containing subscriber records having the highest access rate. This method enables subscriber records to be more economically stored and used than is possible using conventional binary trees and, thereby, increases network capacity.

Scalable Wireless Network Architecture Based On Subscriber Distribution

View page
US Patent:
61482013, Nov 14, 2000
Filed:
Jul 31, 1998
Appl. No.:
9/127104
Inventors:
Hakan Ernam - Dallas TX
Christopher S. Reece - Plano TX
Jim Xu - Plano TX
Assignee:
Nortel Networks Corporation - Montreal
International Classification:
H04Q 720
US Classification:
455433
Abstract:
A wireless communication system constructed according to the present invention assigns mobile units 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 "serving" mobile switching center.

Channel Reservation And Power Control For Improved Handoff Performance

View page
US Patent:
58059954, Sep 8, 1998
Filed:
Oct 28, 1996
Appl. No.:
8/739012
Inventors:
Hua Jiang - Plano TX
Jim Xu - Plano TX
Assignee:
Northern Telecom Limited - Montreal
International Classification:
H04Q 700
US Classification:
455436
Abstract:
A method and system for handing over on-going communications to a target cell including a plurality of low power channels, for handling ongoing calls, and a plurality of higher power channels for handoff. The ongoing call is switched from a low to a higher power channel upon receiving a handoff request. The on-going call is using the higher power channel until a determination is made that the handoff is necessary or unnecessary. The quality of reception of the serving cell and target cell is compared to determine the necessity.

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).
