Abstract

A system and method for exchanging location assistance information between electronic devices (12, 16) using a near field communication (NFC) interface (20). Positioning satellite signals are received from one or more position satellites (14). Location assistance information is generated based at least in part on the received positioning satellite signals and / or navigation information. The location assistance information is transferred through a near field communication interface from the first electronic device to another electronic device, wherein the location assistance information includes one or more contemporaneous positioning satellite signals received by the first electronic device.

Description

technical field [0001] The disclosed technology generally relates to electronic devices, and more particularly, to a system and method for transmitting positioning assistance information between electronic devices. Background technique [0002] Mobile wireless electronic devices are becoming more and more popular. For example, mobile phones, global positioning systems, portable media players, and portable gaming devices are widely used today. Furthermore, the features associated with particular types of electronic devices are becoming increasingly diverse. Many electronic devices have communication capabilities, navigation capabilities, imaging capabilities, text messaging capabilities, Internet browsing capabilities, e-mail capabilities, video playback capabilities, audio playback capabilities, image display capabilities, and hands-free capabilities, to name a few examples. [0003] While mobile electronic devices can provide users with the ability to use many features, c...
