Embodiment 1
[0077] Embodiment 1: The inventor provides a specific example to support the feasibility of the present invention.
[0078] 1) Software and hardware configuration
[0079] In this embodiment, the hardware block diagram of the bluetooth node is as follows figure 2 shown. The bluetooth adopts the DFBM-CF121 module of DETA company, and the firmware below the host control interface layer (Host Control Interface, HCI) of bc02 is programmed in the bluetooth chip. The host computer is a PC, and its Linux installation version is Redhat2.4.20-8. The Bluetooth protocol stack above the HCI layer runs on the PC, using the open source Bluetooth protocol stack BlueZ, and its installed version is bluez-libs-2.3-3, bluez-utils-2.2-3, bluez-libs-devel-2.3-3 . RTP / RTCP uses the open source jrtplib library, and its installed version is jrtplib3.6.0. The sound card model of the PC is VT8233 AC97 Audio Controller. The analog voice digitization and voice playback programming uses the open so...
Embodiment 2
[0095] Embodiment 2: The inventor provides an application model to expand the scope of application of the present invention.
[0096] Such as Figure 8 Shown is an extended application model of multi-hop voice transmission based on Bluetooth technology, in which multiple Bluetooth multi-hop links can be connected to the Internet or GPRS through the gateway, so as to realize the integration of Bluetooth multi-hop links with Internet and GPRS, namely The end nodes in the Bluetooth multi-hop link can communicate with any node in the Internet or GPRS network. Since the Bluetooth multi-hop link provides support for IP, as long as the gateway is modified to connect to other IP networks, the integration of the Bluetooth multi-hop link and other IP networks can be realized.
