International Classification:

H04B 720

US Classification:

455457, 455456, 455414, 455426, 455458

Abstract:

A system and method for locating mobile telephone devices via the Web. The mobile telephone device obtains and provides its location to a Web server in GPS latitude and longitude format. The communication between the Web server and the mobile telephone device may be through a browser or through mobile originated short message service. The Web server records the location information along with the time of receipt. Over time, the Web server may record several locations for a single mobile telephone device so that the progress of the mobile unit may be mapped. The information contained in the Web server is accessible to devices with Web browsing capabilities. A Web browsing device queries the Web server for location information pertaining to a particular mobile telephone device. The Web server may require authorization for such information before sending the location to the requesting device. The location information may be sent in a text only format or as text with graphics, depending on the display capabilities of the requesting Web browsing device.

Appl. No.:

9/245827

Inventors:

William Y. Son - San Diego CA
Jong T. Chung - San Diego CA

Assignee:

Neopoint, Inc. - La Jolla CA

International Classification:

H04B 116
G09G 336

US Classification:

455566

Abstract:

A wireless communication handset includes at least one processor and is configured to shutdown at least one of a display, display backlight and keypad backlight of the handset. A first timer is set when the display is turned on, and the first timer is started to time a display time-out period. If a keypad entry is made by a user during the timeout period, the first timer is reset. On the other hand, if a keypad entry is not made by the user before the time-out period expires, the display is shut off to conserve power. Likewise, a time-out period can be implemented to control automatic shut-off of other power-consuming features such as a display backlight and a keypad backlight. Features can be included to automatically re-enable shut-down features upon the occurrence of events such as the receipt of an incoming call, a keypad entry, or the opening of a flip panel on the handset.

Jong T. Chung - San Diego CA

Assignee:

Neopoint, Inc. - La Jolla CA

International Classification:

H04Q 720

US Classification:

455406

Abstract:

A system and method for providing one or more tiers of alternative rates or rate plans to wireless telephone subscribers utilizes one or more home regions, in which the subscriber can make and receive wireless calls at reduced service rates. The home regions are preferably defined within the wireless subscriber's local calling area and can be defined as a region in proximity with the subscriber's home, office, or other location. Additionally, a second tier of reduced rate services can be provided in another region referred to as the home-perimeter region. The home-perimeter region, in one embodiment, is a subset of the home region, and preferably covers an area somewhat equivalent to the area covered by the subscriber's conventional land line services. As such, the subscriber can make wireless calls in or near his or her home, office, or other location at rates competitive to those offered by land line service providers.
