[0039] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present invention can be more thoroughly understood and the scope of the present invention can be completely conveyed to those skilled in the art.

[0040] Refer to Figure 1-2 , an embodiment of the present invention proposes a terminal call routing method, which is applied to a gateway device with a self-survival function, and the method includes:

[0041] Step 11, sending a detection request to an external server and obtaining a detection result;

[0042] Step 12: Receive a call request sent by a terminal;

[0043] Step 13: Forward the call request of the terminal to the external server or the public switched telephone network according to the detection result.

[0044] In this embodiment, the sequence of the above steps 11 and 12 is not limited by the serial numbers. Without affecting the achievement of the object of the present invention, the sequence between the above steps 11 and 12 can be changed; in this embodiment, a gateway device with self-survival ability can be used to send a detection request to an external server, receive a call request sent by a terminal, and forward the call request; the detection request can be sent in real time or periodically; the terminal can be an Internet phone. By sending a detection request to the external server and obtaining the detection result of the working state of the external server, the call request of the terminal is forwarded according to the detection result, ensuring the stability and continuity of the call request of the terminal and further improving the quality of the call communication of the terminal.

[0045] In an alternative embodiment of the present invention, before the step 12, it further includes:

[0046] Step S11: Receive a subscription configuration request initiated after the terminal is powered on;

[0047] Step S12: Feedback subscription configuration information to the terminal according to the subscription configuration request.

[0048] In this embodiment, the gateway device generates the configuration information required by the terminal according to the subscription configuration request. The configuration information may include information such as the resource address of the gateway device itself or the external server; the gateway device feeds back the configuration information to the terminal to ensure that the terminal can normally use the functions of the gateway device.

[0049] Further, after feedbacking the subscription configuration information to the terminal according to the subscription configuration request, it further includes: receiving a registration request sent by the terminal and forwarding the registration request to an external server for processing. In this embodiment, after the terminal receives the configuration information sent by the gateway device, the terminal sends a registration request to the gateway device, and the gateway device forwards the registration request to the external server after receiving it to implement the registration of the terminal.

[0050] In an alternative embodiment of the present invention, the step S12 may include:

[0051] Step S121: Send the download path of the subscription configuration file to the terminal according to the subscription configuration request, and the terminal downloads the subscription configuration file according to the download path.

[0052] In this embodiment, the gateway device generates a subscription configuration file and the download path of the configuration file according to the subscription configuration request. After the terminal downloads the subscription configuration file through the download path and performs automatic deployment, the registration request can be forwarded through the gateway device.

[0053] In an optional embodiment of the present invention, the step 11 includes:

[0054] Send a detection request to the external server; if the response information feedback by the external server according to the detection request is received, obtain the detection result that the external server is normal; after an interval of a preset duration T, send a detection request to the external server again. If the response information feedback by the external server is not received, obtain the detection result that the external server is abnormal.

[0055] In this embodiment, the detection request includes: a first detection request and a second detection request. After the gateway device sends the first detection request to the external server, if the response information feedback by the external server according to the first detection request is received, obtain the detection result that the external server is normal, which means the external server is online; after an interval of a preset duration T, send the second detection request. If the response information feedback by the external server according to the second detection request is received again at this time, it means the external server is normally online. If the response information feedback by the external server according to the second detection request is not received at this time, obtain the detection result that the external server is abnormal, which means the external server is not online; the first detection request is sent by the gateway device to the external server in real time or at regular intervals, and the second detection request is sent after a preset time interval after the first detection request is sent. The sending of the first detection request and the second detection request ensures real-time monitoring of whether the external server is normal, so as to ensure that the system makes timely adjustments according to the detection results, ensure that the terminal call routing is not affected by the external server, and improve the quality of the terminal call routing; the first detection request and the second detection request may include OPTIONS, and the external server is detected as normal or abnormal through OPTIONS.

[0056] In an optional embodiment of the present invention, the step 13 includes:

[0057] Step 131: If the detection result that the external server is normal is obtained, forward the call request of the terminal to the external server.

[0058] Step 132: if a detection result indicating that the external server is abnormal is obtained, the call request of the terminal is forwarded to a public switched telephone network.

[0059] In this embodiment, it should be known that the order of step 131 and step 132 is not used to limit the order of precedence, but is only used to distinguish the execution actions performed after the gateway device obtains different detection results; when the external server is normal, the gateway device forwards the call request to the external server; when the external server is abnormal, the gateway device forwards the call request to the public switched telephone network to ensure the normal terminal call communication.

[0060] Furthermore, when the detection result of the external server anomaly is obtained, it also includes: receiving a registration request from a terminal; processing according to the registration request of the terminal, and feeding back the processing result to the terminal.

[0061] In this embodiment, when the external server is abnormal, the gateway device no longer forwards the registration request of the terminal to the external server after receiving it. The gateway device processes the registration request and feeds back the processed structure to the terminal to ensure that the terminal can continue to communicate when the external server is abnormal, thereby ensuring the stability and continuity of the system communication.

[0062] The above method will be described below with reference to a specific example, taking the example that the terminal is a VOIP (Voice over Internet Protocol) terminal device and the external server is a cloud IP PBX:

[0063] like Figure 3 As shown, when the external server cloud IPPBX is normal, the call routing steps of the VOIP terminal device are as follows:

[0064] Step (1), the VOIP terminal device is powered on to initiate a subscription configuration request, and the gateway device responds to the request and generates a configuration file, and sends down the configuration path;

[0065] Step (2), the VOIP terminal device downloads the configuration file according to the allocated path;

[0066] Step (3), the VOIP terminal device initiates registration, and the gateway device forwards the registration request to the external server;

[0067] Step (4), the VOIP terminal device initiates a call, and the gateway device forwards the call request to the external server.

[0068] like Figure 4As described above, when the external server cloud IPPBX is abnormal, the call routing steps of the VOIP terminal device are as follows:

[0069] Step (5), the VOIP terminal device initiates registration, and the gateway device acts as a registration server to process the registration request

[0070] Step (6), the VOIP terminal device initiates a call, and the gateway device forwards the call to the public switched telephone network to ensure normal communication even when the external server is not working;

[0071] In this embodiment, it should be noted that whether the external network device is normal or abnormal, before the terminal device initiates a registration request, a subscription configuration request will be initiated first to establish information exchange between the terminal device and the gateway device and use the functions of the gateway device; when the external server is abnormal, through the self-survival ability function of the gateway device, the registration request is processed on the local gateway device without passing through the external server, and the call request of the terminal device is transferred to the public switched telephone network to ensure normal call communication of the terminal device and improve the reliability of call communication of the terminal device.

[0072] Such as Figure 5 shown, an example of the present invention further provides a gateway device, and the gateway device 50 includes:

[0073] A transceiver module 51, configured to send a detection request to an external server, obtain a detection result, and receive a call request sent by a terminal;

[0074] A processing module 52, configured to forward the call request of the terminal to the external server or the public switched telephone network according to the detection result.

[0075] Optionally, before the transceiver module 51 receives a call request sent by a terminal, it further includes: receiving a subscription configuration request initiated after the terminal is powered on; and feeding back subscription configuration information to the terminal according to the subscription configuration request.

[0076] Optionally, the transceiver module 51 feeding back subscription configuration information to the terminal according to the subscription configuration request includes:

[0077] Sending a download path of a subscription configuration file to the terminal according to the subscription configuration request, and the terminal downloads the subscription configuration file according to the download path.

[0078] Optionally, after the transceiver module 51 feeds back subscription configuration information to the terminal according to the subscription configuration request, it further includes: receiving a registration request sent by the terminal; and forwarding the registration request to an external server for processing.

[0079] Optionally, the transceiver module 51 sends a detection request to an external server and obtains a detection result, including: sending a detection request to the external server; if receiving response information fed back by the external server according to the detection request, obtaining a normal detection result of the external server; after an interval of a preset duration T, sending a detection request to the external server again, and if not receiving the response information fed back by the external server, obtaining an abnormal detection result of the external server.

[0080] Optionally, according to the detection result, the processing module 52 forwards the call request of the terminal to an external server or a public switched telephone network, including: when obtaining a normal detection result of the external server, forwarding the call request of the terminal to the external server; when obtaining an abnormal detection result of the external server, forwarding the call request of the terminal to the public switched telephone network.

[0081] Optionally, when obtaining an abnormal detection result of the external server, the processing module 52 further includes: receiving a registration request of the terminal; processing according to the registration request of the terminal, and feeding back a processing result to the terminal.
