The VoIP protocol entity is refined into SIP VoIP application process (SIP VOICE APP) module 307, H238 VoIP application process (H238 VOICE APP) module 308, and H323 VoIP application process (H323VOICE APP) module 309. the

The specific functions of the above modules are:

Flash memory 301: There is a configuration subject, which needs to be initialized before it can be used, and provides an interface for device access;

Configuration management logic module 302: process the interaction of configuring the client, such as setting/obtaining configuration, querying device status, protocol stack switching, etc., manage the internal modules of the configuration entity, and establish an internal module communication routing mechanism;

Process control logic module 303: control the process cycle, record the running status of each process from generation to end;

VoIP management module 304: manage SIP VoIP application process module 307, H238 VoIP application process module 308, H323 VoIP application process module 309, handle the interaction with these three modules, such as VoIP start/stop is completed, device VoIP registration is successful, VoIP is abnormal quit;

VoIP configuration module 305: VoIP configuration analysis, distribution, application to management SIP VoIP application process module 307, H238 VoIP application process module 308, H323 VoIP application process module 309;

Network data reporting module 306: providing necessary network operation data for VoIP;

SIP VoIP application process module 307, H238 VoIP application process module 308 and H323 VoIP application process module 309: entities that carry various protocol stack business processes. the

Above each module participates in the flow process in the embodiment of the present invention, then an example of the VoIP protocol switching method in the embodiment of the present invention comprises: after the system is powered on, the flash memory 301 is partitioned by BootLoad, and the system default configuration is written into; The configuration management logic module 302 reads the VoIP initial configuration information in the system default configuration information of the flash memory 301, initializes the entire management logic module 302, and prepares to run the VoIP application entity. The VoIP management module 304 judges the specific type of the VoIP protocol information according to the read VoIP initial configuration information, and requests the process control logic module 303 to start the VoIP application entity. The process control logic module 303 creates (fork) a child process, and draws a blank process control block, records the process identification number (PID, Process Identifier) of the child process, the corresponding process name, and the running state, and monitors the process The sub-process enters different processing flows according to the exit situation of the sub-process. If it exits abnormally, it will notify the VoIP management module 304 to restart, and if it exits the system normally, it will actively stop running. the

When the VoIP configuration module 305 receives the VoIP startup success message, the configuration of VoIP is applied to the SIP VoIP application process module 307, the H238 VoIP application process module 308, and the corresponding VoIP protocol application process in the H323 VoIP application process module 309.

If the SIP VoIP application process module 307, the H238 VoIP application process module 308, and the corresponding VoIP protocol application process in the H323 VoIP application process module 309 need to wait until the resource release is successful because resources cannot be released, the VoIP management module 304 receives the stop VoIP request confirmation, instructs the process control logic module 303 to terminate the VoIP protocol application process. The process control logic module 303 finds the corresponding VoIP application process module, sends a termination signal to the running VoIP protocol application process, and releases the corresponding VoIP application process module after the VoIP protocol application process exits normally, and reports to the VoIP management Module 304 reports that the VoIP protocol application process has been destroyed. the

The VoIP management module 304 receives the report that the VoIP protocol application process terminates, and according to the task of the current protocol switching, requests the process control logic module 303 to start the VoIP application entity corresponding to the protocol that needs to be switched, and repeats the above-mentioned corresponding steps until the corresponding The VoIP application entity is in a stable running state. the
