Abstract

An electronic device that has a lower portion that unfolds to reveal an extendable keyboard. When the keyboard is folded closed, a number pad is visible and the device looks similar to a traditional portable or cellular telephone. The device can be used as a personal digital assistant, a cellular telephone, a cordless telephone or as the handset of a traditional wire line telephone. The fold-out keyboard of the electronic device can be used for easy entry of text data while a communication channel is active. The device includes two way messaging and Internet browsing capabilities.

Description

technical field [0001] The present invention relates generally to the field of telephones, and more particularly to telephones with deployable keypads. Background technique [0002] Cellular telephones are designed to give the user maximum freedom of movement when using the telephone. Cell phones use radio signals to communicate between the "cell phone" and a base station through an antenna. Somewhat similar to a honeycomb, the service area is divided into multiple cells (cells), and the antennas are placed in each cell and connected to a switchboard dedicated to cellular-telephone calls through telephone lines. The switchboard interconnects the cellular phones and, if the call is between a cellular phone and a non-cellular phone, forwards the call to a conventional switchboard, the public switched telephone network. This special cellular switchboard, controlled by a computer, selects the antenna closest to the phone when service is requested. When the phone is roaming, t...
