摘要:
In accordance with the invention, there is disclosed a system for determining location of a mobile station. The mobile station includes a transceiver operating in a wireless network and a GPS receiver. The system includes a wireless network control system including GPS receivers for obtaining ephemeris data. The control system develops assistance information from the ephemeris data and transmits the assistance information to the mobile station via the wireless network. The assistance information represents range at a fixed location in the wireless network in proximity to the mobile station at a select time, and derivatives of the range, relative to plural select satellites in the GPS. The mobile station utilizes received assistance information for searching the composite received signals from the plural select satellites in the GPS to measure a code phase for plural ones of the select satellites in the GPS and returning the measured code phases to the wireless network control system via the wireless network. The wireless network control system computes location of the mobile station in the wireless network utilizing a fixed location and the measured code phases.

A technique for obtaining caller-originated alert signals in IP-based communication sessions is disclosed. According to one embodiment, the technique may be realized as a method comprising the steps of: receiving, from a first user equipment and via a first communication channel, a request to initiate a communication session, the request being received at a second user equipment; in response to the request, causing a phonepage server to transmit, via a second communication channel, a caller-originated alert to the second user equipment; and rendering the caller-originated alert to alert a user associated with the second user equipment.

A dual mode user terminal for a calling party can make calls over both a conventional cellular network and a packet data network using VoIP protocols. If the called party is not available to receive a VoIP call over the packet data network, the user terminal for the calling party can request a third party user terminal available on the packet data network to relay the call between the calling party and the called party.
摘要:
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.
摘要:
The wireless communication device and corresponding method described herein selectively switches between a single-frequency mode, such as appropriate for an EDGE network, and a multiple-frequency mode, such as appropriate for a multi-carrier EDGE network. Accordingly, a transmitting wireless communication device selectively switches between a single-channel mapping unit, used during the single-frequency mode, and a multi-channel mapping unit, used during the multiple-frequency mode. The multi-channel mapping unit modulates input data to output a modulated data stream for each of multiple adjacent frequency channels that, when combined, produce a multiple-frequency signal with reduced peak-to-average ratio. A receiving wireless communication device selectively switches between a single-channel demodulator, used during the single-frequency mode, and a multi-channel demodulator, used during the multiple-frequency mode.
摘要:
Some embodiments of the present invention provide methods of operating an electronic device, such as a wireless communications terminal, a personal digital assistant and/or a media player, having a personal information manager, such as a scheduling application and/or a contact management application. Data is received at the electronic device, the received data including audio and/or visual content and associated personal information manager data. The personal information manager is controlled responsive to the personal information manager data.
摘要:
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 receives a request for a communication session from a second user's communications device. Upon failure to accept the request, a server automatically forms a calendar data object, 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, and a time is selected. The server then notifies the other device of the selected time. Corresponding devices are also described.

A wireless communication device includes a Near Field Communication (NFC) interface, a transceiver, and a controller. The NFC interface receives data related to multimedia content from an external NFC tag responsive to establishing an NFC link with the NFC tag. Based on the received data, the controller establishes a communication link with a multimedia server via a wireless communication network, and controls the multimedia server to download information associated with the multimedia content to a user-specified destination device.
摘要:
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.
摘要:
A mobile device including a location module configured to determine a location of the mobile device, and a caller identification (ID) and/or caller ID blocking module configured to provide caller ID and/or caller ID blocking features by sending and/or receiving a signal with caller ID and/or caller ID blocking information. The caller identification and/or caller ID blocking module is configured to enable and disable the caller ID and/or caller ID blocking features based upon the location of the mobile device determined by the location module.
