The embodiment of the present invention provides a kind of VoIP protocol switching method and device, in order to according to configuration client-requested, switches different VoIP agreements, increases work efficiency.
Refer to Fig. 1, an embodiment of the VoIP protocol switching method in the embodiment of the present invention comprises:
101, configuration management logic entity receives the order of VoIP protocol switching, obtains the wherein information of VoIP agreement;
In the present embodiment, by controlling the configuration management logic entity in client, configuration access entities, and a plurality of VoIP protocol application entity, the seamless switching that completes the use of VoIP agreement.
After system powers on, configuration access entities is carried out to initialization, configuration access entities is non-volatile access arrangement, for example flash memory (FLASH).Initialization comprises carries out subregion by non-volatile access arrangement, specifically can, by bootstrap loader BootLoad to FLASH subregion, by the format of exclusive configuring area, write acquiescence VoIP configuration information.
Configuration management logic entity is the assembly in VoIP terminal system, bears parsing, access, the application of configuration VoIP information, and the different configuration of coupling client's configuration operation, monitors the activity of VoIP protocol application entity.
VoIP protocol application entity is the maximum part in VoIP terminal system, complete digital signal processor (DSP, Digital Signal Processor) scheduling of resource, the control of speech chip, VoIP control protocol stack is connected, and supplementary service realizes, complexity due to VoIP agreement, cause in the realization of supplementary service reconstruct cost large, every kind of corresponding VoIP protocol application entity of agreement, dispatches it by configuration management logic entity.
Configuration management logic entity receives the order of VoIP protocol switching, obtains the information of the VoIP agreement in this switching command.
102,, according to the information of obtained VoIP agreement, whether VoIP agreement corresponding in the information of the VoIP agreement that judgement is obtained is identical with current VoIP agreement;
Configuration management logic entity is by the VoIP agreement of obtaining in step 101, and according to the information of the VoIP agreement of obtaining, in the information of the VoIP agreement that judgement is obtained, whether the VoIP agreement of correspondence, identical with current operating VoIP agreement.
If the 103 VoIP agreements of obtaining are not identical with current VoIP agreement, to VoIP protocol application entity, send the request that stops current VoIP agreement;
If the result of judgement is that obtained VoIP agreement is not identical with current VoIP agreement in step 102, to current VoIP protocol application entity of working, transmission stops the request of current VoIP agreement.
If it is identical with current VoIP agreement that the result of judgement is obtained VoIP agreement, do not need to switch, continue this VoIP agreement of execution.
104, when monitoring VoIP protocol application entity, stop current VoIP agreement, to VoIP protocol application entity corresponding to obtained VoIP agreement, sent the starting command of the VoIP agreement of obtaining.
Configuration management logic entity monitors VoIP protocol application entity and has stopped current VoIP agreement, to VoIP protocol application entity corresponding to the VoIP agreement of obtaining in step 101, send starting command, order this VoIP protocol application entity to start the VoIP agreement of obtaining.
In the embodiment of the present invention, configuration management logic entity receives the order of VoIP protocol switching, obtain the wherein information of VoIP agreement, whether the VoIP agreement that judgement is obtained is identical with current VoIP agreement, if not, to VoIP protocol application entity, send the request that stops current VoIP agreement, when monitoring VoIP protocol application entity, stopped current VoIP agreement, to VoIP protocol application entity, send the order that starts the VoIP agreement of obtaining, thereby complete the switching between different VoIP agreements, make to adopt the VoIP protocol terminal equipment of this kind of technology can be connected into fast next generation network (NGN, Next GenerationNetwork), and interconnect between other VoIP terminals.
For ease of understanding, with another embodiment, describe the VoIP protocol switching method in the embodiment of the present invention in detail below, refer to Fig. 2, another embodiment of the VoIP protocol switching method in the embodiment of the present invention comprises:
201, configuration management logic entity obtains the information of current VoIP agreement;
Configuration management logic entity obtains the VoIP protocol information in configuration access entities, to know the type of current VoIP agreement.
202, to VoIP protocol application entity corresponding to current VoIP agreement, send starting command;
Configuration management logic entity sends starting command to VoIP protocol application entity corresponding to current VoIP agreement, orders this VoIP protocol application entity to start.
203, when monitoring the startup success of VoIP protocol application entity transmission, to VoIP protocol application entity, send corresponding VoIP protocol parameter;
When configuration management logic entity monitors the startup success of VoIP protocol application entity transmission, general, VoIP protocol application entity starts successfully, while bringing into operation, to configuration management logic entity, sends running status message.Then, configuration management logic entity sends corresponding VoIP protocol parameter to VoIP protocol application entity, the parameter of the corresponding agreement of configuration VoIP protocol application entity, is handed down to current configuration information after VoIP protocol application entity, and VoIP terminal just can turn round in existing network.
204, receive the order of VoIP protocol switching, obtain the wherein information of VoIP agreement;
