Problems solved by technology

It can be seen that although the Bluetooth mobile phone is within the Bluetooth range of the gateway, the incoming call signal is still transmitted through the mobile phone network, and the user still has to endure the interference and attenuation of the Bluetooth mobile phone signal, and the communication fee for answering cannot be reduced

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 ...

Abstract

The invention discloses a method for realizing call shift of Bluetooth mobile phone. The method includes: the gateway receives the application information that the Bluetooth mobile phone applies to join in the network in which the gateway is, and informs the connected outer line telephone number information to Bluetooth mobile phone; the Bluetooth mobile phone registers the telephone number connected by the gateway as the shift number of power-off call shift service; the Bluetooth mobile phone is shut down to the mobile network communication model; the mobile network shifts the call to gateway according to the power-off call shift registered by user, the gateway informs the mobile phone to ring bell. When the Bluetooth mobile phone measures that it left the micro-network of gateway, the Bluetooth mobile phone opens the model communicating the mobile network, and cancels the gateway number through the mobile network, finishes the call shift of the network telephone number. The invention reduces the energy consumption of mobile phone, prolongs the stand-by and communication time; at the same time, the call is transmitted through fixed telephone wire, not through the mobile network, the quality is upgraded, the cost is reduced too.

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 sharp increase in the number of users of Bluetooth mobile phones (including GSM mobile phones, CDMA mobile phones, etc.) (the number of users of Bluetooth mobile phones in my country has exceeded 140 million at present), Bluetooth mobile phone users have higher and higher requirements for network services. 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 Bluetooth mobile phone signals are inevitable. At the same time, the fixed telephone network has also been extended to every household. Compared with...
