US Patent:

7260394, Aug 21, 2007
Filed:

Oct 13, 2004
Appl. No.:

10/964182
Inventors:

William E. Welnick - Poway CA, US
Assignee:

Motorola Inc. - Schaumburg IL
International Classification:

H04Q 7/20
US Classification:

4554321, 455450, 455436
Abstract:

A method () in a CDMA terminal device for acquiring a system identified in an enhanced preferred roaming list (enhanced PRL), with at least one entry containing a mobile country code, includes the steps of obtaining () system identifiers from SYNCH channels on a scan list, determining () if the system identifiers match entries on the enhanced PRL, and inserting () channel information items on a first list if the system identifiers do not match entries on the enhanced PRL. If all channels on the scan list have been scanned without any system identifiers matching entries on the enhanced PRL, the method obtains () mobile country codes using channel information items from the first list, determines () if the mobile country codes match entries on the enhanced PRL, and camps () on a system if its mobile country code matches an entry on the enhanced PRL.

US Classification:

370328, 370342, 455552
Abstract:

A circuit () and method employing logic circuitry () and memory () identifies a reverse link limited channel (). The logic circuitry () identifies a reverse link limited channel based on determining that an access probe failure occurred on a channel (). The logic circuitry () causes the memory to store reverse link limited channel data () in response to the logic circuitry () determining that the access probe failure occurred. The reverse link limited channel data (), for example, may be a channel identification associated with the channel (), a base station identification associated with the channel (), a location identification of the circuit () or any data suitable for identifying and adapting dynamically to the reverse link limited channel.

US Patent:

7466679, Dec 16, 2008
Filed:

Dec 31, 2003
Appl. No.:

10/749819
Inventors:

Samuel J. Liggett - Encinitas CA, US
William E. Welnick - Poway CA, US
Assignee:

Motorola, Inc. - Libertyville IL
International Classification:

H04Q 7/00
US Classification:

370331
Abstract:

A method and system for maintaining registration information for multiple communication areas within a network is provided. For a particular mobile subscriber, information associated with at least some prior registrations are retained, and in some instances are re-used upon re-entry into a communication area in which the mobile subscriber was previously located. The retention of registration information for multiple communication areas is managed as the default, without requiring additional signaling associated with each registration.

US Patent:

7489913, Feb 10, 2009
Filed:

Jan 4, 2005
Appl. No.:

11/028870
Inventors:

William E. Welnick - Poway CA, US
Robert T. Love - Barrington IL, US
Assignee:

Motorola, Inc. - Schaumburg IL
International Classification:

H04B 1/18
US Classification:

455140, 455135, 4552261
Abstract:

A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (), using a first receiver and a second receiver for diversity () if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning () if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.
