In this embodiment, the gravity switch may be a pressure sensor.

In this embodiment, the key module for implementing call transfer is the call management module. After the call management module receives the mobile phone call information sent by the Bluetooth communication module, it performs corresponding processing according to the overall call situation of the current mobile phone call transfer system.

1) When there is an incoming call from the mobile phone but no incoming call from the landline, the incoming call management module sends the incoming call information from the mobile phone to the landline through the telephone interface module, and displays corresponding prompt information through the user panel module. If supported by the base phone, the display screen of the base phone will display the phone number of the incoming call from the mobile phone.

2) When there is an incoming call from the landline but no call from the mobile phone, the incoming call management module sends the incoming call information of the landline to the landline through the telephone interface module, and displays corresponding prompt information through the user panel module. If supported by the base phone, the base phone display shows the phone number of the incoming call from the base phone.

3) When the mobile phone calls and the landline is answering the landline call, the incoming call management module returns busy information to the mobile phone through the Bluetooth communication module, and displays corresponding prompt information through the user panel module.

4) When the landline calls and the landline is answering the mobile phone call, the incoming call management module returns the busy information to the landline, and displays the corresponding prompt information through the user panel module.

Figure 3 shows the basic flow of the mobile phone call transfer system when the mobile phone is calling, and the specific steps are as follows:

Step S3.1: The mobile phone obtains the incoming call sent by the network

Step S3.2: The mobile phone sends the incoming call information to the Bluetooth communication module of the mobile phone call transfer device through the built-in Bluetooth module

Step S3.3: The bluetooth communication module transmits the incoming call information of the mobile phone to the incoming call management module, and the incoming call management module handles it according to the overall incoming call situation of the current mobile phone call transfer system. When there is no call from the landline, go to step 3.4; when there is an incoming call from the landline, go to step 3.5.

Step S3.4: The incoming call management module transmits the incoming call information of the mobile phone to the landline through the telephone interface module, and gives prompt information through the user panel module.

Step S3.5: The incoming call management module returns the busy status to the mobile phone through the Bluetooth communication module, and gives a prompt message through the user panel module.

Figure 4 describes the flow of the mobile phone accessing the mobile phone call transfer system, the specific steps are as follows:

Step S4.1: Turn on the built-in Bluetooth module of the mobile phone;

Step S4.2: Turn on the mobile phone call transfer device;

Step S4.3: Place the mobile phone on the supporting deck of the mobile phone call transfer device;

Step S4.4: The Bluetooth communication module on the incoming call device of the mobile phone is turned on by gravity

Step S4.5: the mobile phone and the mobile phone call transfer device are bound through the Bluetooth protocol;

Step S4.6: The mobile phone call transfer device gives a binding prompt message through the user panel module

Figure 5 describes the process of the mobile phone leaving the mobile phone call transfer system, and the specific steps are as follows:

Step S5.1: The mobile phone is taken out from the supporting holder of the mobile phone call transfer device;

Step S5.2: The Bluetooth communication module on the mobile phone caller device is turned off

Step S5.3: Unbind the mobile phone and the mobile phone caller device

Step S5.4: The mobile phone call transfer device gives a prompt message for unbinding through the user panel module

In this embodiment, the working mechanism of switching the mobile phone call transfer mode to the fixed phone mode is as follows:

After the incoming call management module receives the mobile phone incoming call information sent by the Bluetooth communication module, it detects the state of the line that will be connected to the telephone line, and judges whether the line is not occupied according to the electric signal of the telephone line. If it is found to be occupied, the incoming call management module returns a busy instruction of the telephone line. If it is not occupied and the telephone line is in an idle state, then the circuit is adjusted to switch the voice path, the user terminal is connected to the circuit of the mobile phone incoming call, and the central office circuit (fixed telephone terminal circuit) is disconnected. At this time, the mobile phone provides the electrical signal required by the phone and generates a ringing signal.

The line state detection of the above-mentioned telephone line is to judge whether the telephone line is busy according to the different states of the electric level on the telephone line. The voltage of the telephone is about 30v ~ 40v when it is not talking, 48v when it is ringing, and about 5v after picking up the answer. Therefore, in this embodiment, if the voltage of the telephone line is less than 23V, it is considered that the telephone line is occupied and in a busy state, and the incoming call management module generates a busy command and returns it to the Bluetooth communication module. In this embodiment, the incoming call management module provides a busy instruction for the Bluetooth communication module, so that the Bluetooth communication module generates an AT instruction (ie, an Attention instruction) of AT+CHUP\r, and returns it to the mobile phone. When the voltage of the telephone line is not less than 23V, disconnect the fixed line connection line, connect the mobile phone call forwarding line, and provide 5v level to the fixed line network interface at the same time, simulating the busy state of the fixed line network, so that in the mobile phone call forwarding mode , incoming calls over the fixed network will automatically return a busy status to the caller.

In addition, the mobile phone call transfer device in this embodiment can cooperate with multiple mobile phones, that is, the mobile phone call transfer device can be bound to multiple mobile phones. But at the same time, the mobile phone call transfer device only cooperates with a mobile phone placed on the deck.

The specific embodiments described above have described the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above content is only a specific embodiment of the present invention, and is not intended to limit the present invention. All modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
