An AAL2 link guess algorithm for Iub interface in WCDMA network

In the existing technology for Iub interface AAL2 link parameters configuration there are business interruption,less flexibility and poor expansibility.To solve these problems,an AAL2 link guess algorithm for Iub interface was presented in the paper.With the guess algorithm configurations protocol data unit each layer have for each data frame,in accordance with the FP,MAC and RLC sequence,the pre-guess will traverse three channels(RACH,FACH,PCH).The success guessing parameter was derived from the max value of the success pre-guess parameter and will be written to the configuration file.The algorithm was implemented in WCDMA monitoring system.The experimental results show that the signaling messages of Iub interface can be analyzed accurately and completely.It played an important role for Iub interface signal monitoring and protocol analysis.
