Description

Incoming call bridging method and mobile communication device

The invention relates to an incoming call bridging method and a mobile communication device, in particular to an incoming call bridging method and a mobile communication device without a telephone exchange switchboard.

With the advancement of technology, mobile communication devices have become more and more popular, and the portability of mobile communication devices allows users to carry them around and can be used in many occasions anytime and anywhere. However, once the user forgets to carry the mobile communication device out of the door or is not near, he will not be able to answer the call in time and may miss important calls.

To this end, the traditional way is to use the Internet Protocol Private Branch Exchange (IP PBX) to transfer incoming calls to the network phone. However, with the IP PBX for telephone transfer, the mobile communication device usually has to be connected to the IP PBX to complete the transfer. In other words, it is still necessary to connect to the external switchboard system to complete the call transfer, which will cause inconvenience to the user. At the same time, the construction of the switchboard system also requires additional costs. Therefore, the prior art is necessary for improvement.

Accordingly, it is a primary object of the present invention to provide an incoming call bridging method and a mobile communication device that do not require a telephone exchange switchboard to solve the above problems.

The present invention provides an incoming call bridging method, including: establishing a network telephone connection to a second communication device when a telephone call from a first communication device is not answered within a first period; And a communication path between the first communication device and the second communication device to transmit voice data about the incoming call when the network telephone connection is connected.

The invention further provides a mobile communication device, comprising: a control unit, configured to establish a network to a second communication device when a call from a first communication device is not answered within a first period of time a telephone connection; and a modulation and demodulation unit for receiving and transmitting voice data related to the telephone call of the first communication device; a memory; wherein the control unit is connected to the modulation and demodulation unit And the memory to establish a communication path between the first communication device and the second communication device, so that the voice data about the incoming call is transmitted when the network telephone connection is turned on.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a mobile communication device 1 according to an embodiment of the present invention. The mobile communication device 1 includes a control unit 102, a modulation and demodulation unit 104, and a memory 106. The control unit 102 is configured to establish a network telephone connection to a second communication device when a call from a first communication device is not answered. Further, the control unit 102 is configured to connect the modulation and demodulation unit 104 and the memory 106 to establish a communication path between the first communication device and the second communication device. The modulation and demodulation unit 104 can receive and transmit voice data related to incoming calls. In this way, when the network telephone connection established by the control unit 102 is turned on, the purpose of the telephone transfer can be realized by transmitting the voice data about the telephone call through the established communication path.

In detail, regarding the operation mode of the mobile communication device 1, please refer to FIG. 2, which is a schematic diagram of a process 20 according to an embodiment of the present invention. According to the process 20, it is assumed that the first communication device at the far end makes a telephone call to the mobile communication device 1. In this case, when the mobile communication device 1 receives a telephone call from the first communication device, it starts counting and determines whether the telephone call has been answered within a first period (step 202). If the incoming call is answered during the first period, the mobile communication device 1 performs a general call function (step 204). If the incoming call is not answered within the first period, the mobile communication device 1 performs a telephone bridge function to transfer the incoming call to a second communication device. Therefore, the control unit 102 establishes a network telephone connection to the second communication device when the telephone call is not answered within the first period (step 206). In more detail, when the incoming call is not answered within the first period, the control unit 102 then activates a call hold function to reserve the call. Then, the control unit 102 dials a corresponding network phone to the second communication device according to the preset network phone contact. When the corresponding network telephone is answered, the control unit 102 cancels the previously activated call reservation function, so that the network telephone connection is successfully established.

In addition, when the incoming call is not answered within the first period, the control unit 102 is further connected to the modulation and demodulation unit 104 and the memory 106 to establish a relationship between the first communication device and the second communication device. A communication path, such that the voice data relating to the incoming call will be transmitted when the network telephone connection is turned on (step 208). That is to say, a communication path is formed between the modulation and demodulation unit 104 and the memory 106 by the processing of the control unit 102. At this time, for the incoming call, the voice data about the downlink of the first communication device will be received by the modulation and demodulation unit 104 and transmitted to the memory 106 for storage. Then, the voice data stored in the memory 106 and associated with the downlink of the first communication device can be transmitted to the second communication device through the established network telephone connection. Similarly, for the incoming call, voice data relating to the downlink of the second communication device will be received and stored in memory 106 via the established network telephone connection. The voice data stored in the memory 106 with respect to the downlink of the second communication device will be transmitted to the modulation and demodulation unit 104 for transmission to the first via the modulation and demodulation unit 104 and the associated radio frequency module. Communication device. In short, when the incoming call from the first communication device is not answered within the first period, the mobile communication device 1 establishes a connection to the second communication device through the control unit 102, and in the first communication device and the second communication device. A communication path is provided between the communication devices to transmit voice data about the incoming call of the phone. Therefore, the user can receive and transmit the incoming call by using the communication path between the first communication device and the second communication device by answering the incoming call of the second communication device. The purpose of the telephone call bridging is achieved by the associated voice material (step 210).

For example, in an embodiment, referring to FIG. 3, the control unit 102 can be a radio interface layer (RIL) component and/or a driver layer (Kernel Layer) component of the mobile communication device operating system. to realise. It is assumed that the first communication device at the far end makes a telephone call to the mobile communication device 1. If the user does not carry the mobile communication device 1 and cannot answer the incoming call within the first period (for example, within 20 seconds), the mobile communication device 1 performs a telephone bridge function to transfer the call to the call. The second communication device. At this time, the control unit 102 activates a call hold function to reserve the call, and makes a network call to the second communication device according to the preset network telephone contact. When the corresponding network telephone is answered by the second communication device, the control unit 102 cancels the call reservation function, so that the network telephone connection with the second communication device is established. At the same time, the control unit 102 also turns on the connection relationship between the modulation and demodulation unit 104 and the memory 106. Once the network telephone connection is connected, it will be used to transmit voice data about the incoming call. . In this case, if the user forgets to carry the mobile communication device 1 and arrives at the place where the second communication device is located (for example, in an office or other networked environment), the mobile communication device 1 receives the voice call and is not received. In the case of answering, the network call will be dialed to the second communication device through the aforementioned bridging mechanism. Therefore, the user can receive the incoming call of the second communication device and receive and transmit the related voice data of the incoming call through the communication path between the first communication device and the second communication device. And achieve the purpose of telephone transfer. In this way, even if the user forgets to carry the mobile communication device 1, the telephone call can be received without missing any incoming calls.

On the other hand, please continue to refer to FIG. 3, the path bridge relationship between the traditional voice telephone and the network telephone is as follows, the signal transmission downlink of the voice telephone: the modulation and demodulation unit 104 via the P2 pin → code decoding (codec ) P3 pin of unit 108. The signal transmission uplink of the voice telephone: The code decoding unit 108 modulates the P1 pin of the demodulation unit 104 via the P4 pin. The signal transmission downlink of the network telephone: P5 pin of the memory 106 → P3 pin of the code decoding unit 108. The signal transmission uplink of the network telephone: the P4 pin of the codec unit 108 → the P6 pin of the memory 106. That is to say, the conventional mobile communication device transmits the voice data received by the modulation/demodulation conversion unit 104 or the voice data of the network telephone received via the memory 106 when performing a normal telephone call. To the code decoding unit 108, the conversation content is broadcasted by the speaker. And the user's voice is transmitted through the microphone and then transmitted to the modulation and demodulation unit 104 or the memory 106 via the codec unit 108. In contrast, when the mobile communication device 1 of the present invention performs the telephone bridging mechanism, since the mobile communication device 1 does not answer the incoming call, the associated voice data is not transmitted to the code decoding unit 108. In actual operation, the present invention forms a transmission path between the modulation and demodulation unit 104 and the memory 106 through the arrangement processing of the control unit 102 to provide communication between the first communication device and the second communication device. path. In this case, when the control unit 102 establishes a connection with the network telephone of the second communication device, it can be used to transmit the voice data related to the telephone call to achieve the purpose of the telephone bridge. That is to say, the downlink of the voice data of the present invention is the P2 pin → P6 → memory 106 of the modulation and demodulation unit 104 by the arrangement processing of the control unit 102. The uplink of the speech data of the present invention: the P5 pin of the memory 106 → the P1 pin of the modulation demodulation unit 104.

In summary, the traditional telephone switching mode mobile communication device usually has to be connected to a traditional telephone exchange switchboard or a network telephone exchange switchboard to be transferred. In contrast, the mobile communication device of the present invention does not need to be connected to the telephone exchange switchboard. The present invention establishes a network telephone connection and establishes a communication path through the control unit to transmit voice data related to the telephone call to achieve the purpose of telephone bridging. In this way, in addition to saving the cost of the construction of the telephone exchange switchboard, the unanswered telephone calls can be immediately transferred to the network telephone end without missed the telephone call. The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
