Patent number: 6031825Abstract: A system for providing an IR-link between a mobile phone and its accessories to transmit audio, control, and data signals between them in an apparent full-duplex real time mode using a conventional half-duplex IR-transceiver with suitable FIFO registers and control means. The "direction" of the half-duplex channel is "switched" by the system which may be embodied in an IR-link module, having transmission channels for digital full-duplex audio signals, slow data messages and fast data messages, and for some control data. The module is connected to the baseband of a phone through a baseband interface (BBIF) and communicates through a media interface (MIF) and an infrared interface (IRIF) with free air space or a lightguide. A link-specific low-level protocol is used for audio and slow data message transmission but the link hardware of the module may also support other protocol implementations. The system may be implemented in hardware and/or software.Type: GrantFiled: July 23, 1996Date of Patent: February 29, 2000Assignee: Nokia Mobile Phones LimitedInventors: Terho Kaikuranta, Markku Lipponen, Seppo Jarvensivu, Toni Sulavuori
