System, method, and device for scheduling a future time for a communication session

A method for scheduling another time for a communication session when a called party is presently unable or unwilling to accept an incoming call. A first user's communications device (100) receives a request for a communication session (from a second user's communications device (100). Upon failure to accept the request (210), a server (170) automatically forms a calendar data object (230), such as in response to receipt of a scheduling trigger message from the first communications device that includes an indication of the failure to accept and an identifier of the second user. The calendar data object includes scheduling information indicating, explicitly and/or implicitly, future time(s) when the first user is available. The calendar data object is sent to either one of the devices (100), and a time is selected (240). The server (170) then notifies the other device (100) of the selected time (250). Corresponding devices are also described.

Adaptively selecting signal constellations for peak-to-average ratio improvement in mult i -carrier edge

Wireless transmitter switches between single-frequency EDGE mode and multicarrier EDGE mode. In single-frequency EDGE mode the transmitter uses a single-channel mapping unit and the receiver uses a single-channel demodulator. In multicarrier EDGE mode the transmitter uses a multi-channel mapping unit and the receiver uses a multi-channel demodulator. In multicarrier EDGE mode there is a high peak-to-average ratio. The multi-channel mapping unit uses one of the following solutions to overcome this: 1) a rotational offset (that is a phase offset ) between the constellations on the different channels; 2) jointly choosing the constellation transforms used on each of the frequency channels to produce the best, or an acceptable peak-to-average ratio; 3) offsetting the timing of modulation between the frequency channels so that the same constellation point does not occur on different frequency channels simultaneously..

Evolved edge receiver

The wireless receiver of the present invention accommodates dual-carrier Evolved EDGE without significantly impacting existing receiver architectures. The inventive receiver comprises a shared local oscillator and two image-rejecting downconverters. The local oscillator generates a local oscillator frequency between two carrier frequencies of adjacent radio channels. The receiver receives a signal in each of the adjacent radio channels. In a dual-carrier mode, a first image-rejecting downconverter uses the local oscillator frequency to downconvert a first signal received in the first radio channel while rejecting a second signal received in the second radio channel. A second image-rejecting downconverter uses the local oscillator frequency to downconvert the second signal while rejecting the first signal. In a diversity mode, the first and second image-rejecting downconverters use the local oscillator frequency to downconvert the signal received in one of the radio channels while rejecting the signal received in the other radio channel.

Active acoustic multi-touch and swipe detection for electronic devices

An electronic device has a display, a controller, and a pair of haptic transducers connected to the display. The controller configures the haptic transducers to momentarily vibrate the display. A pair of sensors disposed on the display detects variations caused by the user touch in the vibrations. Based on an analysis of these variations, the controller can determine whether a user performed at least one of a swipe action and a multi-touch action, across the display.

Event triggered pairing of wireless communication devices based on time measurements

An event-triggered pairing mechanism allows pairing wireless devices having short range interfaces (e.g., Bluetooth devices) by bumping the wireless devices together. A wireless device being paired with a connecting device detects a bump event, determines time information about the bump event, and then generates a private session key based on the time information. Once the devices are paired and the private session key is generated, user content can be securely exchanged between the devices.

A method and apparatus for routing emergency calls in a voip system

Methods and apparatuses for routing emergency calls originated from mobile wireless devices in a Voice-over-IP (VoIP) system (10) are described herein. In one or more embodiments, emergency calls are routed in a VoIP system (10) by receiving incoming emergency calls originated from dual-mode mobile devices (12) connected to the VoIP system (10) through wireless access points (WAPs) (14), determining locations associated with the incoming emergency calls, and redirecting callers to a cellular network (38). In other embodiments, emergency calls are routed in a VoIP system (10) by mapping WAP identifiers to emergency answering points (EAPs) (30), receiving an incoming emergency call from an originating WAP (14), identifying an EAP (30) relating to the originating WAP (14), and directing the emergency call to the identified EAP (30).

System and method for dynamically updating and serving data objects based on sender and recipient states

Methods and apparatus for managing the distribution of data objects (265) in a communication network are disclosed. In an exemplary method, such as might be implemented at a data object server (215), a plurality of data objects (265) corresponding to a first user of a first communication device (205) are stored. State information (270) for the first communication device (205) is received from the first device. The occurrence of a trigger event related to communications between the first communication device (205) and a second communication device (210) is detected, and one of the stored data objects (265) is selected, based on the detected trigger event and the received state information (270), and forwarded to the second communication device (210). In some embodiments, the selection of the data object is further based on an identifier corresponding to the second communication device (210).

Methods, mobile stations and systems for acquiring global positioning system timing information

Methods, systems and mobile stations are provided which determine GPS timing by collecting energy from transmitted signals from one and preferably more acquired satellites to determine a single timing value, which may increase sensitivity. In addition, the receiver devices may use the entire navigation message from each satellite to obtain timing information which may further improve sensitivity and possibly remove latency from having to wait for the time-of-week (TOW) field to be received in the GPS satellite transmission. This is preferably accomplished by maximizing a single delay metric created based on expected (known in advance from some source) and actual (received) navigation symbols from the acquired satellites. As a result, position fixes may possibly be obtained under disadvantaged conditions where the signal quality from the GPS satellites is poor. Furthermore, the timing information obtained pursuant to the present invention does not require a timing relationship between GPS and communication network time.

Interference reduction in high-speed wireless data networks

Methods, apparatus, and systems are described, in which mobile stations in gaps between conventional cells obtain access to high speed data services by initiating an ad hoc, peer-to-peer connection with an intermediary mobile station and transmitting an access request message to the intermediary mobile station for relaying to a nearby base station. Upon receiving such an access request, a base station determines the approximate location of the mobile station, estimates an angular direction from the base station to the mobile station, and forms a directed antenna beam aimed towards the mobile station for transmission of high speed data to the mobile station. Corresponding techniques in which a base station initiates the establishment of a high speed data link are also disclosed.
