Referring to FIG. 3, which is a schematic diagram of steps of a voice control method provided by an embodiment of the present invention, the method may include the following steps:

Step 301: Perform a preprocessing operation on the received session initiation protocol SIP configuration request to obtain a first sub-SIP configuration request.

Optionally, perform a preprocessing operation on the received session initiation protocol SIP configuration request to obtain the first sub-SIP configuration request, which specifically includes one or a combination of the following operations:

The operation of parsing the configuration request: parsing the received session initiation protocol SIP configuration request to obtain a first sub-SIP configuration request and a second sub-SIP configuration request;

Save configuration operation: save the parsed first sub-SIP configuration request and the second sub-SIP configuration request;

Distributing configuration request operation: Distributing the first sub-SIP configuration request and the second sub-SIP configuration request.

Further, the distribution configuration request operation can be performed in the following two ways:

method one:

The first sub-SIP configuration request is parsed to obtain the SIP user circuit attribute configuration, the configuration is delivered to the user plane through the southbound interface, and the user circuit SIP attribute is configured through the user plane. The SIP user circuit attributes include: SIP control mode (local SIP control, VOIP-CP SIP control), dial matching mode (local number matching, VOIP-CP number matching), dial plan table and the like.

Method two:

Parse the second sub-SIP configuration request to obtain the SIP protocol service related configuration, and deliver the configuration to the SIP protocol component through the iCM-SIP. The configuration distribution module in the SIP protocol component distributes the configuration.

Further, when the configuration distribution module in the SIP protocol component distributes the configuration, it can be specifically executed as follows:

Step 1: Distribute the SIP protocol related configuration to the SIP protocol module. The SIP protocol-related configuration includes a SIPAgent, a protocol-related timer, and the like.

Step 2: Distribute the SIP service related configuration to the SIP service module. The configuration related to the SIP service includes a dial plan table, playback duration, and the like.

Step 3: Distribute the gRPC client-related configuration to the gRPC client module.

Step 302: Control the user plane to establish a calling media session according to the first sub-SIP configuration request.

Optionally, when the control user plane establishes the calling media session according to the first sub-SIP configuration request, step 302 is specifically performed as follows: parsing the circuit attribute configuration in the first sub-SIP configuration request, if the SIP user circuit attribute If "SIP Control Mode" is configured as "Local SIP Control", the SIP VOIP control process is handled in the original way of the traditional access gateway.

Further, under the configuration of "VOIP-CP SIP control", the user circuit of VOIP-UP goes off-hook, when configured according to the "dial matching mode" attribute of the SIP user circuit, the specific implementation can be as follows:

Step 1: If it is "local number matching", start dial matching processing on VOIP-UP, complete all dialing on VOIP-UP, and report the matching result to the SIP service module. The SIP service module executes the fourth step after receiving the matching result.

Step 2: If it is "VOIP-CP number match", report the off-hook event to the VOIP-CP.

Step 3: After the SIP service module receives the off-hook event, it starts the dial-up matching process, interacts with the VOIP-UP for dial-up, and completes the dial-up match.

Further, after the SIP service module receives the off-hook event, the dial matching process is started, and the dialing interaction with VOIP-UP is performed. When the dialing matching is completed, the specific execution can be as follows:

Step (1): Notify VOIP-UP to play dial tone.

Step (2): VOIP-UP dial-up report.

Step (3): carry out dial matching processing, if the dial matching is completed, end, otherwise go to step (4).

Step (4): Notify VOIP-UP to dial the next number and return to step (2).

Step 4: The SIP service module applies to VOIP-UP to create a VOIP channel resource according to the dial-up matching result, and then notifies the SIP protocol module to start the SIP session establishment process and exchange SIP signaling with the SIP proxy.

Step 5: The SIP protocol module issues a ringback tone instruction to the SIP service module, the SIP service module forwards the release instruction to the VOIP-UP, and the VOIP-UP user plays the ringback tone after receiving the instruction.

Step 6: The SIP protocol module issues a session establishment success command to the SIP service module, the SIP service module issues a bidirectional VOIP channel establishment command to the VOIP-UP, and the VOIP-UP completes the channel establishment.

Step 303: Control the user plane to establish a called media session according to the first sub-SIP configuration request.

Optionally, when the control user plane establishes the called media session according to the first sub-SIP configuration request, step 303 may be specifically performed as follows:

In the first step, the SIP protocol module sends a ringing command to the SIP service module, and the SIP service module forwards the command to VOIP-UP; the VOIP-UP user rings after receiving the command.

In the second step, the VOIP-UP user goes off-hook and reports the off-hook event to the VOIP-CP.

In the third step, after receiving the off-hook event, the SIP service module applies to VOIP-UP to create a VOIP channel resource, completes the establishment of a two-way VOIP channel, and then notifies the SIP protocol module to complete the SIP session establishment.

Step 304: Control the user plane to release the media session.

Optionally, when controlling the user plane to release the media session, step 304 may be specifically performed as follows:

In the first step, when the user on one side of the VOIP-UP hangs up, the VOIP channel resources are released, and the on-hook event is reported to the VOIP-CP.

Step 2: After the SIP service module receives the on-hook event, it notifies the SIP protocol module to start the SIP session release process, and exchanges SIP signaling with the SIP proxy.

Step 3: After receiving the SIP signaling of session release, the SIP protocol module on the VOIP-CP of the other party notifies the SIP service module to play the busy tone, and the SIP service module forwards the notification to the VOIP-UP to play the busy tone.

Step 4: The VOIP-UP user hangs up to release the VOIP channel resources, and informs the SIP service module that the resources are released successfully.

Through the above technical solution, the SIP module is separated from the gateway device and placed in the cloud server. The virtualized SIP component software runs on the server and remotely controls the establishment and release of the VOIP media channel on the gateway device through a standardized API interface. There is no need to change the device version when the SIP component version is upgraded, and services will not be interrupted, realizing a smooth transition during the version upgrade process; at the same time, it has the advantages of server memory and CPU resources, and the performance of large calls will not be affected.
