摘要： Apparatus and method are provided for discovery and networking of proximate devices using acoustic messaging. In one novel aspect, a peer discovery protocol is used to discover proximate devices using voting messages encoded in ultrasonic waveform. In one embodiment, the UE receives one or more voting messages from neighboring UEs encoded in ultrasonic waveform, builds its voting message and broadcasts the voting message encoded in ultrasonic waveform. In another embodiment, based on the voting result, a multi-tier wireless LAN is established by the master UEs through two RF interfaces. In another novel aspect, an optimized synchronization by the receiver is used to locate the transmitted frame boundary of the ultrasonic message. In one embodiment, the UE reversed-looks up a pre-calculated boundary-offset table to estimate the tone boundary and searches the maximum synchronization tone energy down to per sampling interval using a predefined search algorithm to optimize locating the tone boundary.

摘要： Apparatus and method are provided for a group gaming platform for mobile devices in proximity. In one novel aspect, a Game Directory Service provides an ad-hoc game list to all registered UEs. A registrar UE collects locally installed games from registered subscriber UEs and updates the list based on trigger events. In another novel aspect, the Executable Distribution Service is provided to expedite the downloading. A game-host UE sends a united resource location of an installer for the group game to all invited UEs together with the invitation message. In another novel aspect, Remote Game Hosting Service enables a passive-client UE to play a group game without installing the game locally. The passive-client UE relays detected sensor readings to a passive-host UE. The passive-host UE uses peer messaging and scene streaming to run the game logic and to stream the scene sequences to one or more passive-client UEs.

摘要翻译： 提供装置和方法用于使用声学信息发现和联接邻近的装置。 在一个新颖的方面，使用对等体发现协议来发现使用以超声波形式编码的投票消息的邻近设备。 在一个实施例中，UE从以超声波波形编码的相邻UE接收一个或多个投票消息，建立其投票消息并广播以超声波波形编码的投票消息。 在另一实施例中，基于投票结果，由主UE通过两个RF接口建立多层无线LAN。 在另一个新颖的方面，使用接收机优化的同步来定位超声波消息的传输帧边界。 在一个实施例中，UE反向查找预先计算的边界偏移表以估计音调边界，并且使用预定义的搜索算法将最大同步音调下降到每采样间隔，以优化定位音调边界。
