Step 7, the main transmission to spare module with module needs synchronous business information;
Step 8, spare module sends the ARP request to main with module;
Step 9, repeating step 7,8 breaks down with module up to main, and spare module is upgraded to the main module of using.
On the basis of technique scheme, the said master of step 7 sends to spare module with module needs synchronous business information to comprise following concrete steps:
Step 71, the master sends the current RTP port numbers with module to spare module;
Step 72, the master sends current arp entry with module to spare module;
Step 73 if the master receives user action with module, is then transmitted the user side action message to spare module;
Step 74 if the master revises session connection with module, is then transmitted session connection to spare module;

On the basis of technique scheme; The said spare module of step 1 powers on; Send announcement information with module and be meant to main: if spare module with main with module at same device interior; Spare module only need send to the main module of using as announcement information with its mac address information, otherwise spare module need send to the main module of using as announcement information with its IP address information.
On the basis of technique scheme; Lead in the step 2 with module before spare module sends configuration information; Main active and standby with the communication mechanism between the module with setting up earlier between module and spare module; If at same device interior, directly the intercommunication mechanism through equipment realizes, otherwise realizes through the SOCKET communication mechanism with module for spare module and master; Said configuration information comprises address, the port numbers of soft-switch platform, the main local port number with module with the soft-switch platform swap data, the main local ip configuration information and the main local VOIP voice configuration information with module with module of soft-switch platform at least; After spare module was received whole configuration informations, spare module was accomplished announcement information to main with module transmission configuration information synchronously.
On the basis of technique scheme, after step 7 executes, active and standbyly at first together go on foot complement mark with tense marker with module, and then execution in step 8.
As stated, the synchronous process that powers on being arranged after spare module powers on, mainly is to be synchronized to spare module with main with module configuration information and business information at this moment.Specifically: after spare module powers on, the first, spare module execution in step 1 is communicated by letter the main existence with module oneself of notice with main foundation with module; The second, main with module execution in step 2～5, will lead with modules configured information etc. and send to spare module; And inquire about spare module and whether register the information that completing steps 2 to 4 is sent, the configuration information in the step 2 comprises signaling ip/ mask/gateway, medium ip/ mask/gateway; Local port number; Soft-switch platform information, WMG domain name, configuration information that each port user name or the like is relevant with the NGN agreement and relevant voice configuration information with speech business; What send out in the step 3 is the MGC information of current use; What send out in the step 4 is the information which port is opened speech business; The 3rd, spare module execution in step 6 is initiated to confirm with module to main, confirms it and has accomplished the registration of step 2 to 4 each information of being sent; The 4th, main with module execution in step 7, give spare module synchronously with main business information with module; The 5th, spare module sends synchronous complement mark, active and standby with module with the synchronous complement mark of tense marker.Synchronous this link that powers on spare module finishes, and begins real-time data sync, and promptly repeating step 7,8, breaks down with module up to main, and spare module is upgraded to the main module of using.Synchronously complement mark is put on after step 7 is carried out, it just sign this link that powers on synchronously accomplish, when having execution in step 7 when synchronous in real time, but can not indicate this flag bit once more yet.The master sends current arp entry with module in spare module powers on synchronism link to spare module; Be that current arp entry is synchronized to spare module; Current master also need arp entry synchronous in the real-time data sync link, because can cause the increase and decrease of arp entry with the dynamic change of call-information on the module.
(master is the main module of use among the figure, is equipped with to coil to be spare module) as shown in Figure 2, spare module power on handling process specifically the branch following components realize:
1, the main module of using of spare module notice.If the position that needs the notice spare module at same device interior, only needs the mac address information of notice spare module, if spare module with main independent with module, then need be notified the IP address information of spare module.
2, the main information of putting forward according to spare module with module is set up active and standby with the communication mechanism between the module.Same equipment can realize that external equipment is taked the SOCKET communication mechanism through intercommunication.
3, the master sends to spare module with module with existing configuration information.The address, the port that comprise soft switch, local ip and port, VOIP voice configuration information (containing domain name, port name) etc.
4, spare module request synchronous protocol has related parameter.
5, the master sends current media gateway controlling MGC information with module to spare module.
6, after all configuration synchronization are accomplished, the master sends configuration synchronization with module to spare module and accomplishes.
7, the main information synchronization that will converse this moment with module is to spare module.Main with all link informations of conversing of module collection, the order of composition signaling sends to spare module.Spare module is ordered according to these, connects synchronously at spare module, and is consistent to reach active and standby information with module.Spare module is to be responsible for the backup master with module configuration data and business datum; But realization mechanism of the present invention is to issue spare module with module with the form of signaling packet through main; Resolve by spare module oneself, carry out then, be equivalent to carry out the whole process that connects this signaling of creating.
8, the main transmission with module accomplished mark synchronously to spare module.Active and standbyly accomplish mark synchronously with tense marker, the active and standby simultaneous data sync of beginning back with module.
Secondly, active and standbyly exist simultaneously, accomplish the synchronous process that powers on after, spare module needs the main synchronously in real time information with module.Because spare module is only used module communication with the master, so all need synchronizing information all send to spare module by main with module, notice has informational needs synchronous.Main with module when having user side event handling, signaling process and new configuration to obtain, all needs elder generation with relevant information synchronously to spare module, carry out relevant treatment work again.And as long as spare module is with the synchronizing information of receiving; Correspondingly handle, this handle with main processing with module this moment unique different be exactly that spare module does not send any information to module is outer, target is exactly to accomplish and main synchronous with module status; When guaranteeing to switch in real time; Spare module can be upgraded to the main module of using immediately, launches to use, and realizes active and standby seamless switching.
In this link, need synchronous information to divide three aspects, see Fig. 3 for details:
(1) user action information; The master needs earlier this information is sent to spare module with module; The master almost is converted into signaling data with user action information simultaneously with module and spare module then; To organize good signaling bag by the master with module and send to soft-switch platform; Spare module is only accomplished related data and state synchronization, does not externally send the signaling bag;
(2) the soft-switch platform signaling that receives; The master also needs earlier this information is notified to spare module with module, then accomplishes signaling and resolves, and carries out the preceding preparation of user side action; Notify user side to carry out relevant action at last; After spare module is received synchronizing information, also need accomplish signaling and resolve and relevant preparation, but not notify user side to carry out actual operation;
(3) configuration information that issues from main control module; The master at first notifies spare module will carry out the change of relevant configuration with module; Realize own module configuration information change again, after spare module is received the synchronous update command of configuration information, also can be updated to latest configuration in real time.
Active and standby existence simultaneously in real time synchronously provides assurance for active and standby seamless switching, and the very key so this link becomes is moved below needing to accomplish:
1, after the master receives user's action with module, at first these is moved synchronized transmissions to spare module, again these actions are sent to soft switch with the signaling form.(seeing Fig. 4 for details)
2, after spare module was received and led the user action that sends over module, all were walked by normal flow, but these signalings are not sent to soft switch.
3, main when receiving the order that soft switch gets off with module, at first these orders are sent to spare module, and then handle.(seeing Fig. 5 for details)
4, spare module is received main soft switch order of coming synchronously with module, handles by normal flow.
5, main when receiving the configuration that main control module issues with module, also to give spare module synchronously with configuration information.(seeing Fig. 6 for details)
When 6, spare module is received main new configuration information of coming synchronously with module, need to change be configured to consistent with the main module of using.
At last, when main with module when running into the fault paralysis, can realize the active and standby switching of using module, the master moves back with module and is spare module, and spare module can be upgraded to the master fast and uses module, realizes the speech business function well.On the basis of second fine realization of link, this link becomes simple relatively on the contrary at last, mainly is the transformation that realizes active and standby sign, and the master is with the exchange (seeing Fig. 7 for details) of the spare module essential information of module preservation.When active and standby switching starts, can accomplish the conversion of active and standby sign by hardware, and the hardware completion, in time, consumed still less.
Main with after the module switching, the master with self resetting as spare module, repeats above process, to reach the impregnable purpose of customer service with module again.
Among the present invention, no matter come to user side information, or the soft-switch platform signaling; Or configuration information; Main backup module all carries out the processing of identical information separately, and such way is to hope active and standby synchronizing information with module is reduced as much as possible, alleviates the load of main backup module communication.Real-time synchronizing information has guaranteed active and standby strict conformance with module data, and making active and standbyly becomes possibility with the module real-time reversion, guarantees active and standby seamless switching.
In this main backup module redundancy backup mode that the present invention adopts; The information of the real-time synchronous interaction of main backup module is signaling packet; Adopt this mechanism; Can reduce active and standby synchronizing information as much as possible, alleviate the main backup module traffic load, and can also guarantee active and standby strict conformance with module data with intermodule.On the basis of this mechanism, the required work of doing just becomes seldom when switching, and making active and standbyly becomes possibility with the module real-time reversion, guarantees the seamless switching of main backup module.
In the soft switch agreement, megaco protocol or MGCP agreement belong to principal and subordinate's control protocol.For SGW, it belongs to Be Controlled one end, and groundwork is: accomplish action with the user and convert signaling into and issue soft switch, the order of sending according to soft switch then changes the attribute of ustomer premises access equipment, reaches the purpose of setting up conversation.When two kinds of agreements are used on the SGW, identical property is arranged on realization mechanism, this invention is with being applicable to two kinds of agreements of MEGACO and MGCP simultaneously.
