Embodiment Construction

[0021] figure 1 is a system block diagram of a Bluetooth headset (gateway or headset). exist figure 1 Among them, the Bluetooth headset device 100 is composed of several functional modules. Among them, the Bluetooth headset phone application 110 provides various functions of the headset to the user, and the required voice is provided by the baseband controller 150 ; the required control signaling is provided by the FRCOMM protocol 120 . The standard communication protocol L2CAP (Logical Link Control and Adaptation Protocol) 130 multiplexes various protocols of the upper layer. HCI (Host Control Interface) driver 175 allows sending standard HCI commands and receiving responses resulting therefrom; and receiving and sending data through L2CAP 130 . The HCI transport layer 180 is optional. When the upper layer functional modules and the lower layer functional modules of the HCI transport layer are running on different processor platforms, the HCI transport layer is responsible...

Abstract

The invention discloses a method for automatic call shift of Bluetooth earphone. The method includes: the Bluetooth earphone couples with the gateway, and enters the searching state; in the searching state, the earphone is in call scanning mode, the gateway call the earphone; the gateway create connection to the earphone and assures the quality has enough security, then the earphone and the gateway enter the holding state; in the holding state, if the quality is stable, the gateway registers the mobile phone number fixed network, the ear phone and the gateway enters the on-line state; in the on-line state, when the fixed telephone call the mobile phone, the call is transformed to the gateway, then uses the Bluetooth earphone to receive the call; in the on-line state, the close and connection between the earphone and the gateway or the quality is decreased to the threshold value, the gateway logouts the mobile phone number, the gateway and mobile phone enters the searching state. When the earphone and the gateway have the cal shifting function, the user needn't to bear the interruption and fading of mobile phone signal, the quality is upgraded. The saves the speak time, at the same time; it prolongs the communication and waiting time.

Description

technical field [0001] The invention relates to bluetooth technology in the field of wireless communication. Background technique [0002] In the prior art, there is a short-distance wireless communication technology called Bluetooth (Bluetooth), which operates in the 2.4GHz ISM (Industrial-Science-Medical) frequency band. The basic network structure of Bluetooth is a piconet (Piconet) composed of a master device and up to seven slave devices. The master device and slave devices communicate by means of time division multiple access (TDMA). Using Bluetooth technology, various devices can be connected in a low-cost way. The Bluetooth Special Interest Group (SIG) is a non-governmental organization that formulates and guides Bluetooth specifications and applications. In its defined headset application framework (Headset Profile), it proposes a way to use Bluetooth technology to realize wireless headsets. That is, both the voice gateway and the headset are equipped with a Bluet...
