Embodiment Construction

[0023] figure 1 It is a system block diagram of a Bluetooth cordless phone device (gateway or terminal). exist figure 1 Among them, the Bluetooth cordless phone device 100 is composed of several functional modules. Wherein, the bluetooth cordless phone application 110 provides various functions of the cordless phone to the user, and its required voice is provided by the baseband controller 150; supply. 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 for the information transmission ...

Description

technical field [0001] The invention relates to the field of bluetooth mobile phone and bluetooth communication technology in wireless communication, in particular to a call processing method. Background technique [0002] With the rapid increase in the number of users of cellular phones (including GSM mobile phones, CDMA mobile phones, PHS mobile phones, 3G mobile phones, etc.) high. Although the current mobile phone network almost covers the entire earth, and the signal can reach special areas such as subways and elevators, however, the signal of the mobile phone network is unstable to a certain extent. Between high-rise buildings and indoors, interference and attenuation of cellular phone signals are unavoidable. [0003] At the same time, the fixed telephone network has also been extended to every household. Compared with mobile phones, the biggest advantages of landline phones are: stable and reliable signal, and cheap communication costs. [0004] At present, cellu...
