Abstract:

For realizing SlAP monitor in LTE network, the implementation scheme of SlAP protocol monitoring module was designed to cope with the insufficiency of protocol decoding and CDR synthesis research scheme effetiveness, on the base of introducing LTE network monitor software platform. The scheme adopted the thought of separating definition and realization for message decoding, improving the code independence and portability. The use of Hash index and overtime management mechanism of SlAP message synthesis ensured the accuracy and validity of synthesis. The scheme had been successfully applied to LTE network monitor. It has been proved to have a good effect by simulation data for testing.

Key words: LTE, SlAP, protocol monitor, Hash index
