摘要: In the preliminary authentication stage, mobile station (35) is authenticated by sending from home network (30) to roamed (31), a plurality of pairs first random numbers (RNDa 1 , . RNDa n ) and calculation results (SRESa SRESa cipher function (f), which performed at using secret key (ki) RND an ), sending, station, third formed coupling second (RNDb RNDb m produced with RNDan), network, SRESb )) sent numbers, confirming, coincidence network. main authentication, pair number result (SRESb respect station.
