Abstract

The present invention discloses a Bluetooth relay device and a method to realize the relay, which are suitable for wireless communication systems of Bluetooth terminals and Bluetooth gateways. The device comprises a processor module arranged with a memory for a Bluetooth protocol stack at an intermediate operation layer and an upper layer and to realize conversion between a Bluetooth earphone protocol and a cordless phone protocol, a Bluetooth module connected with the processor module and arranged with a Bluetooth radio frequency and base band processing chip, a power amplifier and a low-noise amplifier respectively connected with the Bluetooth radio frequency and base band processing chip to operate a lower layer of Bluetooth protocol stack, communicate with the processor module and conduct receiving/sending of Bluetooth radio frequency and base band processing. The present invention realizes interconnection between a Bluetooth earphone or a handheld Bluetooth terminal and a voice gateway based on a Bluetooth cordless phone protocol in a specific scope, thus making full use of fixed network resource, improving call quality and reducing call expense.

Description

technical field [0001] The invention relates to a device for wireless radio frequency relay and protocol conversion based on bluetooth technology, in particular to a method and device for realizing portable wireless voice and data relay and conversion based on bluetooth technology. Background technique [0002] As a short-distance and low-cost wireless communication technology, Bluetooth technology is attracting more and more people's attention. A large number of mobile phones, PDAs, and notebook computers are embedded with Bluetooth modules, and Bluetooth data gateways and Bluetooth voice gateways have emerged as the times require. In recent years, Bluetooth technology is expanding from the original headset, phone book transmission and other applications to cordless phones, stereo headsets and other applications, which requires more and more Bluetooth communication distance, bandwidth and Bluetooth protocol support. At present, a large number of PDAs (Personal Digital Assis...
