Adjusting Maximum Transmit Power To Maintain Constant Margin For Adjacent Channel Power Rejection

View page
US Patent:
6374116, Apr 16, 2002
Filed:
Sep 22, 1999
Appl. No.:
09/401578
Inventors:
Paul Peterzell - San Diego CA
Sheikh A. Hafiz - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04B 104
US Classification:
455522, 455 69, 455115, 455126, 455138, 4552321, 4552501
Abstract:
A method of adjusting transmit power in a CDMA portable phone to maintain adjacent channel power rejection (ACPR) passing margin includes the steps of amplifying a first radio frequency (RF) signal according to a first gain to produce a second RF signal, and amplifying the second RF signal according to a second gain to produce a third RF signal. A desired power level of the third RF signal is determined and a new gain value is computed from the desired power level. The first gain value is adjusted to the new value. A system for adjusting transmit power in a CDMA portable phone to maintain adjacent channel power rejection (ACPR) passing margin includes an automatic gain control (AGC) amplifier having an AGC input terminal, an AGC output terminal, and a control signal input terminal. The system also includes a power amplifier (PA) having a PA input terminal and a PA output terminal, wherein the PA input terminal is connected to the AGC output terminal. In addition, the system includes an output power controller having a controller input terminal and a controller output terminal, wherein the controller input terminal is connected to the PA output terminal and the controller output terminal is connected to the AGC input terminal.

System And Method For Establishing A Communication Link Between A Mobile Station And A Base Station Controller

US Patent:
6505042, Jan 7, 2003
Filed:
Jun 10, 1999
Appl. No.:
09/332257
Inventors:
Sheikh A. Hafiz - San Diego CA
Assignee:
Qualcomm, Incorporated - San Diego CA
International Classification:
H04Q 720
US Classification:
455434, 455552, 455458
Abstract:
A system including a user station that prioritizes multiple cell sites (BTSs) based on the strength of a paging message being transmitted by the BTSs. The user station transmits a response message to one of the BTSs transmitting the paging message based upon selecting the access channel associated with the BTS from which the user station received the paging message having the strongest signal strength until a timeout period has expired, and subsequently transmits the response message on the access channel associated with the BTS from which the user station received the paging message having the next strongest signal strength. The user station includes a receiver to receive the paging message transmitted by multiple BTSs. The user station further includes a processor to analyze and prioritize the multiple BTSs into a sequence according to the signal strength of the paging message received. Coupled to the processor is a timer for timing the timeout period.

Facilitating Transfer Of Push And Pull Messages For Remotely Testing Mobile Devices

US Patent:
8284682, Oct 9, 2012
Filed:
May 16, 2008
Appl. No.:
12/122615
Inventors:
Rana Huq - San Diego CA, US
Sheikh Ashik Hafiz - San Diego CA, US
Assignee:
QUALCOMM, Incorporated - San Diego CA
International Classification:
G01R 31/08
US Classification:
370250, 455424
Abstract:
Providing for remote field testing of mobile communication devices is described herein. By way of example, network initiated data received at a mobile device or like device activated on a mobile network can be monitored. Further, an over the air (OTA) message sent by the mobile network to the monitored device can be identified and forwarded to a test device. Additionally, an IP gateway of the mobile network can be monitored for mobile originated pull messages or network originated push messages associated with or identifying the test device. A data translator can reconfigure or reroute data to and from the mobile device and mobile network utilizing information associated with the activated device. Accordingly, remote data exchange can be implemented even if the mobile device is not pre-activated on the mobile network.

Providing Remote Field Testing For Mobile Devices

US Patent:
20090207745, Aug 20, 2009
Filed:
May 16, 2008
Appl. No.:
12/122580
Inventors:
Rana Huq - San Diego CA, US
Sheikh Ashik Hafiz - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
G06F 11/00
US Classification:
370252
Abstract:
Remote field testing of mobile communication devices is provided herein. By way of example, an IP gateway of a target mobile network can be monitored. A mobile originated data packet associated with a test device can be updated or translated to include information of a device that is activated on the mobile network. Likewise, a mobile network originated data packet, routed to the activated device and/or identifying the test device, can be forwarded to the test device. As described herein, two way data exchange between the mobile network and the test device can be implemented even if the test device is not pre-activated on the mobile network. Further, an interface for the two way communication can comprise any suitable Internet Protocol (IP) network, enabling application testing remote from wireless access points of the mobile network.

Voice Activated Mobile Telephone Call Answerer

US Patent:
6349222, Feb 19, 2002
Filed:
Feb 1, 1999
Appl. No.:
09/241809
Inventors:
Sheikh A. Hafiz - San Diego CA
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H04Q 732
US Classification:
455569, 455568, 455563, 455550, 455567, 455347, 379 8801, 379 8802, 379 8803, 379 8804
Abstract:
A mobile telephone system and a method for answering a mobile telephone incoming call by a users verbal command, to allow hands-free voice. The mobile telephone system includes a carkit and a mobile telephone. The mobile telephone has a programming key for pre-programming the users voice greeting, a keypad for answering the call in telephone mode, a microphone for entering a users verbal command for answering the call in carkit mode, a digital processor connected to the microphone for performing spectrum analysis and feature extractions of the users verbal command in carkit mode, and a memory connected to the digital processor, having a database for storing the users pre-programmed voice greeting digitized speech pattern. The pre-programmed voice greeting may be a factory-programmed voice greeting or the users pre-programmed voice greeting, if previously initialized after pressing the programming key. The digital processor performs spectrum analysis and feature extractions of the users verbal command for determining if a match exists between the users verbal command and the stored user pre-programmed voice greetings.
