Abstract: Operation of a satellite-based navigation-signal broadcast system receiver, such as a GPS receiver, on a wireless communications device is controlled by determining whether the device is stationary or in motion. Motion determination is accomplished by analyzing radiofrequency signal traces, e.g. GSM signal traces, received from one or more nearby base stations. A three-tiered analysis provides a progressively more accurate determination as to whether the device is moving or stationary while providing, in certain instances, a more rapid determination than prior-art techniques. When the device is determined to be stationary, the GPS receiver can be deactivated. When the device is determined to be moving, the receiver can be reactivated.

Abstract: First and second communication devices respectively have first and second personal identification numbers (PINs). The first communication device transmits to the second communication device a first encryption key, and receives from the second communication device the second PIN that has been encrypted by the second communication device using the first encryption key. The first communication device receives from the second communication device a second encryption key, decrypts the encrypted second PIN, and encrypts the first PIN using the second encryption key, and transmits the encrypted first PIN to the second communication device. The first communication device conducts, with the second communication, device a peer-to-peer messaging session by transmitting to the second communication device peer-to-peer messages that contain the second PIN and receiving from the second communication device peer-to-peer messages that contain the first PIN.

Abstract: A radio frequency radio (RF) transceiver that defines scheduling logic for generating transmission schedules for orthogonal frequency-division multiple access (OFDMA) RF transmissions from the RF transceiver, wherein the scheduling logic specifies at least one of a modulation type, a code rate, a sub-channel, and a sub-carrier for a plurality of symbols to be transmitted in a communication signal sub-frame. A processor generates outgoing data bits and outgoing test data bits for transmission from the RF transceiver as OFDMA transmission signals and OFDMA test data transmission signals, respectively, according to the transmission schedules to create loading within at least a portion of a cellular service area that corresponds with a test-loading value. The amount of the additional required loading is the difference between the test-loading value and an actual loading value.

Abstract: An electronic device and wireless base station for maintaining a persistent connection are provided. In an embodiment, a system includes an electronic device that connects to a web-server via a physical link that is bandwidth-constrained. The physical link also includes a wireless base station and at least one network address translation (“NAT”) router that is configured to terminate idle connections between the client and the web-server. One of the electronic device and the wireless base station is configured to send keep-alive packets to the web-server in order to reduce the likelihood of the NAT router terminating the connection. The keep-alive packets are sent on a variable basis that is intended to reduce bandwidth consumption while ensuring that the NAT router does not deem the connection idle and terminate the connection.

Abstract: An improved handheld electronic device includes an input apparatus, an output apparatus, and a processor apparatus. The input apparatus includes a multi-axis input device such as a rollerball, trackball, joystick or touchpad, allowing the focus of a user interface program to be moved about a display from one screen object presented on that display to another. Up to four screen objects are presented on the display, each of those screen objects being positioned towards a corner of the display to enable a user to blindly operate the multi-axis input device, making use of a capture effect in which the focus of a user interface program is resisted from moving beyond an edge of the display, to guide movement of the focus to a given one of the up to four screen objects.

Abstract: An improved handheld electronic device having a reduced keyboard provides facilitated language entry by making available to a user certain words that a user may reasonably be expected to enter. In some situations, certain words can be stored, for example, in a temporary dictionary for use in particular situations. For instance, the names of the recipients of an electronic message might be stored in a temporary dictionary for rapid retrieval when entering a salutation in the message. As another example, a number of the words in an existing electronic message may be stored in a temporary dictionary and made available to a user when replying to or forwarding the message since the existing message might include words that the user might reasonably be expected to type in the reply message or the forwarded message.
