Detailed ways

The main realization principles, specific implementation modes and corresponding beneficial effects of the technical solutions of the embodiments of the present invention will be described in detail below in conjunction with each accompanying drawing.

In order to solve the problems existing in the prior art, an embodiment of the present invention provides a method for proxying network voice services, as shown in FIG. 1 , including the following steps:

Step 101, after receiving the request for entering the energy-saving state sent by the VoIP service device, the device proxying the VoIP service regularly sends a heartbeat message to the softswitch application layer;

Step 102, when the device acting as an agent for the VoIP service receives the call request sent by the softswitch application layer, it replies with a ringback tone to the softswitch application layer, and sends an activation message to the VoIP service device;

Step 103, after receiving the end energy-saving status request returned by the VoIP service device, the device acting as an agent for the VoIP service forwards the call request to the VoIP service device, and stops replying the ringback tone to the softswitch application layer;

In step 104, the device for proxying the VoIP service forwards the received ringback tone sent by the VoIP service device to the softswitch application layer.

Because the network voice service device in the ONT in the prior art must keep working at all times, it consumes a lot of resources of the user terminal. To solve this problem, the embodiment of the present invention establishes a device for acting as an agent for voice over network service at the optical line terminal. When the voice over network device enters an energy-saving state, it will replace it and maintain the working state. Specifically, the specific process for the VoIP service device to register with the softswitch application layer through the device for proxying the VoIP service provided by the embodiment of the present invention includes: after the device for proxying the VoIP service receives the registration request sent by the VoIP service device, Record the registration information carried by the registration request, and build an image of the voice service device according to the registration information; then forward the registration request to the softswitch application layer; after receiving the registration confirmation message returned by the softswitch application layer, you can send the The status of the image is changed to registered, and the registration confirmation message is forwarded to the VoIP service device.

After completing the registration process, the device acting as an agent for the VoIP service receives the request to enter the energy-saving state sent by the VoIP service device, and in the name of the VoIP service device, regularly sends a heartbeat message to the softswitch application layer, so that the softswitch application layer confirms the VoIP status. The service device is still in the working state, for example, using the IP address in the registration information of the VoIP service device to send a heartbeat message to the softswitch application layer, or using other features that can represent the VoIP service device. When the Internet voice service enters the energy-saving state, if it receives a call request sent by the softswitch application layer, it will directly reply the ringback tone to the softswitch application layer, and send an activation message to the Internet voice service device. After receiving the activation message, the VoIP service device ends the energy-saving state to work normally, and notifies the device acting as an agent of the VoIP service. After receiving the end energy saving state request returned by the VoIP service device, the device proxying the VoIP service forwards the call request to the VoIP service device, and stops replying the ringback tone to the softswitch application layer. Then, forward the received ringback tone sent by the VoIP service device to the softswitch application layer.

Through the above process, the VoIP service device can enter the energy-saving state without a call request, and the device proxying the VoIP service will replace it with the softswitch application layer for heartbeat interaction according to the content in the registration information of the VoIP service device, saving energy. resources of the user terminal. And when there is a call request, activate the VoIP service device to restore it to a normal working state.

Of course, the VoIP service device can actively end the energy-saving state. For example, the VoIP service device can actively send a request for ending the energy-saving state to the device acting as an agent for VoIP service, and enter normal work after the device acting as an agent for VoIP service replies to a confirmation message. state.

When the above-mentioned device acting as an agent of the VoIP service detects that the VoIP service device is offline and has not received the logout request sent by the VoIP service device, it sends a logout request to the softswitch application layer; after receiving the logout confirmation message returned by the softswitch application layer, Log off the VoIP service device.

From the above description, it can be seen that using the method for proxying the VoIP service provided by the embodiment of the present invention, when the VoIP service device is in the energy-saving state, instead of maintaining the working state, the VoIP service is activated when a call request is received The device ensures that the resources of the user terminal are saved when the user terminal normally uses the VoIP service.

The process of registering the VoIP service device with the softswitch application layer through the proxy VoIP service device will be described in detail below, as shown in Figure 2, perform the following steps:

Step 201, the VoIP service device sends a registration request to the softswitch application layer;

Step 202: After the device for proxying the VoIP service intercepts the registration request, it records the registration information carried by it; the registration information includes user identification code, softswitch IP address and other information.

Step 203, the device acting as an agent of the VoIP service establishes an image of the VoIP service device according to the registration information; that is, establishes an agent of the VoIP service device according to the information carried in the registered registration information, which can be performed as a VoIP service device Information exchange.

Step 204, the device for proxying VoIP services forwards the registration request to the softswitch application layer;

Step 205, after receiving the registration request, the softswitch application layer replies with an authentication message;

Step 206, the device acting as an agent for the VoIP service forwards the authentication message to the VoIP service device;

Step 207, the VoIP service device sends authentication registration information;

Step 208, the device for proxying the VoIP service forwards the authentication registration information to the softswitch application layer;

Step 209, the softswitch application layer replies with a registration confirmation message;

Step 210, the device proxying the VoIP service forwards the registration confirmation message to the VoIP service device, and changes the status of the image of the VoIP service device to registered.

After the above steps, the device acting as an agent of the VoIP service can replace it to maintain the working state when the VoIP service device enters the energy-saving state, as shown in Figure 3, including the following steps:

Step 301, the VoIP service device sends a request to enter the energy-saving state to the device that acts as an agent for the VoIP service;

Step 302: The device acting as an agent for the VoIP service replies to the VoIP service device with an energy-saving status confirmation message

Step 303, the device that acts as an agent for VoIP services regularly sends a heartbeat message to the softswitch application layer;

Step 304: After receiving the heartbeat message, the softswitch application layer replies a heartbeat confirmation message to the device acting as an agent for voice services over the Internet.

In this way, the device for proxying the VoIP service, in the name of the VoIP service device, interacts with the softswitch application layer for heartbeat messages in real time or periodically, so that the softswitch application layer confirms that the VoIP service device remains in the working state.

When the VoIP service device actively ends the energy-saving state, as shown in Figure 4, the following steps are performed:

Step 401, the VoIP service device sends a request to end the energy saving state to the device acting as an agent for VoIP service;

Step 402: After receiving the request for ending the energy-saving state, the device acting as an agent for the VoIP service replies with an acknowledgment message for ending the energy-saving state, and stops sending heartbeat messages to the softswitch application layer;

Step 403: After receiving the confirmation message of ending the energy-saving state, the VoIP service device sends a heartbeat message;

In step 404, the heartbeat message received by the device acting as an agent for VoIP service is forwarded to the softswitch application layer.

Through the above steps, the VoIP service device changes from the energy-saving state to the normal working state, and the device acting as an agent for the VoIP service stops sending heartbeat messages, so as to avoid reporting errors at the softswitch application layer.

When the network voice service device is in the energy-saving state, when the softswitch layer application layer sends a call request, as shown in Figure 5, the following steps are performed:

Step 501, the application layer of the softswitch layer sends a call request to the device acting as an agent for Internet voice services;

Step 502a, the device acting as an agent for the VoIP service returns a ringback tone to the application layer of the softswitch layer;

Step 502b, the device acting as an agent for the VoIP service sends an activation message to the VoIP service device; the step 502a and step 502b are two steps performed simultaneously;

Step 503: After receiving the activation message, the VoIP service device sends a request to end the energy-saving state to the device acting as an agent for VoIP service;

Step 504, the device acting as an agent for the VoIP service sends a call request to the VoIP service device, and stops replying to the ring-back tone to the softswitch application layer;

Step 505, after receiving the call request, the VoIP service device sends a ringback tone to the softswitch application layer, and rings the user terminal;

Step 506, the device for proxying the VoIP service forwards the ringback tone sent by the VoIP service device to the softswitch application layer;

Step 507: After detecting the off-hook action of the user terminal, the VoIP service device sends an off-hook message;

Step 508, the device acting as an agent for VoIP service forwards the off-hook message to the softswitch application layer;

Step 509, the softswitch application layer replies with an off-hook confirmation message;

In step 510, the device proxying the VoIP service forwards the off-hook confirmation message to the VoIP service device.

Through the above steps, it can be known that when the VoIP service device is in the energy-saving state and the application layer of the softswitch layer sends a call request, the device acting as an agent for VoIP service will respond to the softswitch layer instead of the VoIP service device and activate VoIP at the same time The service device ends the energy-saving state.

When the VoIP service device is abnormally offline, as shown in Figure 6, the following steps are included:

Step 601, when the device for proxying the VoIP service detects that the VoIP service device is offline and has not received the logout request sent by the VoIP service device, it sends a logout request to the softswitch application layer;

Step 602, after receiving the logout request, the softswitch application layer sends a logout confirmation message to the device acting as an agent for VoIP services;

Step 603: After receiving the deregistration confirmation message, the device proxying the VoIP service deregisters the image of the VoIP service device.

Through the above steps, the VoIP service device is formally deregistered in the softswitch application layer, and the image of the VoIP service device in the device acting as an agent for the VoIP service is also deregistered.
