Implementing method for network entity to separately independent control protocol heart-beat

Abstract

Provided is an implemental method for a network entity to independently control protocol heartbeats, which is to transmit heartbeats information between network elements such as a gateway, a media server,etc., the network elements are those successful login of soft-switch, the transmission period of the heartbeats information is self-controlled by the transmitter, and survival statuss of the opposite terminal is found in time, so scheduled countermeasures are adopted in time according to the variety of the opposite terminal such as the scheduled transmission period, response results to the heartbeats information of the opposite terminal network entity from each equipment. The present invention adopts each network entity of H.28 protocol, heartbeats information is indepedently and self-controlled transmitted between the soft-switch and the network equipment without mutual interference and restriction, discontinuity of a chain-route is determined by an information retransmission mechanism which adopts the H.248 protocol, so the survival statuss of the opposite terminal is found by both the soft-switch and the network equipment, scheduled countermeasures are adopted in time according to the variety of the opposite terminal, and then the network performance and the operation function quality are improved.

Description

technical field [0001] The present invention relates to a technology for solving the reliability of Internet-based User Datagram Protocol (UDP) transmission of protocol messages between soft switches and gateway devices. Specifically, it relates to a method for implementing independent control of protocol heartbeats by network entities, belonging to Softswitch network communication technology field. Background technique [0002] The softswitch network is a layered network in which the signaling control layer and the underlying bearer are completely separated. In addition to the media connection control function between the softswitch MGC and the media gateway MG, a certain mechanism is required due to the unreliable transmission of the UDP protocol. To realize the discovery function of fault detection and fault recovery between the two devices, and reduce the impact of device faults on network services by adopting a set business processing strategy. [0003] The H.248 proto...

Problems solved by technology

[0008] This method is very inflexible and has many disadvantages: the gateway does not have an independent heartbeat message, and must be able to "set the sleep time, and after the sleep time is reached, be able to judge the link failure between it and the softswitch and start the relevant strategy" function; and the heartbeat message sent by the softswitch must be subject to the gateway, that is, the softswitch must ensure that the time interval for sending messages to the gateway does not exceed the maximum sleep time

This makes the performance of softswitches and gateway devices more difficult, complicated to set up, and difficult to implement, that is, it is easy to fail to implement the above-mentioned heartbeat mechanism due to device performance, and it is misjudged as a link interruption

Especially in the case of many types of gateways, a softswitch needs to set multiple maximum sleep times, which is very difficult to implement in the entire network

Moreover, the maximum sleep time of the gateway is always set to 7 times the heartbeat period of the softswitch, which is also very unreasonable, because the length of the heartbeat period of the softswitch will directly affect the efficiency of the gateway in judging link interruptions

Therefore, the current heartbeat method is a method that consumes equipment performance and is inefficient. Relying on it cannot guarantee that the equipment can accurately and timely detect and judge link interruptions.
