IMSI (International Mobile Station Identity) is a unique number associated with all GSM and UMTS network mobile phone user. IMSI filtering—a prefix filtering, is an important function in the 3G firewall. It is an indefinite filtering which affects the efficiency of the security device. This paper brings forward a parallel processing method which uses vector coding and structure of bloom filter. This method is realized in Intel network processor—IXP 2850. The features of parallel multithreads and hash unit in network processor are taken advantages. The experiments show the excellent performance of the method in 3G firewall.
