OAM (Operations, Administration and Maintenance) system is a very important component of the 3G cellular network. In order to acquire overall management, fast response and steady operation, a SCTP (Stream Control Transmission Protocol) based OAM (SOAM) system is proposed. The SOAM system implements the new characters of SCTP such as multi-stream, enforced SACK and heartbeat mechanism on its transport layer, which helps to decrease the message transmission delay and accelerate the link failure detection. Moreover, a new component named SOAM agent is introduced to improve the operation efficiency of the SOAM system. Test results prove that SOAM system achieves better performance on signaling transmission compared with conventional TCP based OAM system.
