Description
Technical field
The present invention relates to a kind of reliability engineering that transmits protocol message between soft switch and the gateway device based on the User Datagram Protoco (UDP) UDP of the Internet that is used to solve, exactly, the implementation method that relates to a kind of network entity to separately independent control protocol heart-beat belongs to the flexible exchanging network communication technical field.
Background technology
Flexible exchanging network is that a signaling key-course carries the hierarchical network that separates fully with bottom, wherein between soft switch MGC and the media gateway MG except needs medium connection control function, because it is unreliable that udp protocol transmits, also need to realize the fault detect between these two equipment and the discovery feature of fault recovery, and reduce the influence that equipment fault produces Network by the Business Processing strategy of taking to set by certain mechanism.
H.248 agreement is a kind of interface protocol that is applied between gateway controller and the gateway, also is one of the most active communication protocol of present industry.Now based on Softswitch technology with based on the next generation network (comprising 3G network) of instantaneous communication system IMS, all adopt H.248 agreement as the first-selected agreement between network core control section (as soft switch, IMS etc.) and the media gateway, for the user provides solution.
At present, in the flexible exchanging network, carry out signaling control by agreement H.248 between soft switch and the media gateway, the medium of being finished calling by soft switch control media gateway connect.But the existing H.248 standard of IETF and ITU approval has only been carried out general definition to framework, function, order and the parameter of agreement, does not relate to the regulation of heartbeat mechanism aspect.
For this reason, the domestic standard tissue has defined a kind of heartbeat mechanism scheme of only being controlled by soft switch between soft switch and gateway at present, is implemented as follows:
Soft switch MGC adopts audit parameter value order AuditValue message as heartbeat message, periodically sends to media gateway MG, and the transmission cycle can be set.When heartbeat message retransmits the response message of all not receiving gateway for 7 times, then judge gateway fails, i.e. the link down of itself and gateway.
Simultaneously, soft switch is that gateway is set a maximum sleep time, and soft switch must guarantee that the time interval that sends message to gateway is no more than the maximum sleep time.The suggestion maximum sleep time is 7 heart beat cycles.When gateway at 7 heart beat cycles all not when soft switch receives any message from soft switch, then judge the soft switch fault, i.e. the link down of gateway and soft switch.
This mode is very dumb, disadvantage is more: gateway does not have independent heartbeat message, must possess the function of " dormancy time is set, and after dormancy time reaches, can judges the link down fault between itself and the soft switch and start corresponding strategies "; And soft switch transmission heartbeat message must be limited by gateway, i.e. soft switch must guarantee that the time interval that sends message to gateway is no more than the maximum sleep time.So just make soft switch and gateway device all strengthen the performance difficulty, complexity is set, realize difficulty, promptly be easy to because the reason of equipment performance causes normally realizing above-mentioned heartbeat mechanism, and mistake is judged as link down.Particularly under the more situation of gateway type, a soft switch need be provided with the multiple maximum sleep time, and the whole network is implemented very difficulty.And the maximum sleep time of gateway always is set to 7 times of soft switch heart beat cycle, and is also very unreasonable, because the length of soft switch heart beat cycle can directly influence the efficient that gateway is judged the link down fault.Therefore, present this heartbeat method is a kind of method that expends equipment performance, inefficiency, relies on it can not guarantee that equipment detects accurately and timely and judges link down.Therefore, how to adopt a kind of reasonable, feasible method to solve the integrity problem that transmits protocol message between soft switch and the gateway device based on the User Datagram Protoco (UDP) UDP of the Internet, just become the new problem that the insider pays close attention to.
