    • In the preliminary authentication stage, the mobile station (35) is authenticated by sending from the home network (30) to the roamed network (31), a plurality of pairs of first random numbers (RNDa.sub.1, . . . , RNDa.sub.n) and calculation results (SRESa.sub.1, . . . , SRESa.sub.n) of the cipher function (f), which calculation is performed at the home network using the secret key (ki) and the first random numbers (RNDa.sub.1, . . . , RND.sub.an), by sending, from the roamed network to the mobile station, third random numbers formed by coupling second random numbers (RNDb.sub.1, . . . , RNDb.sub.m) produced at the roamed network with the first random numbers (RNDa.sub.1, . . . , RNDan), by sending, from the mobile station to the roamed network, calculation results (SRESa.sub.1, . . . , SRESa.sub.n, SRESb.sub.1, . . . , SRESb.sub.m)) of the cipher function (f), which calculation is performed at the mobile station using the secret key (ki) and the sent third random numbers, and by confirming, at the roamed network, coincidence of the calculation results (SRESa.sub.1, . . . , SRESa.sub.n) sent from the mobile station with the calculation results (SRESa.sub.1, . . . , SRESa.sub.n) sent from the home network. In the main authentication, the mobile station is authenticated by using a pair of the second random number (RNDb.sub.1, . . . , RNDb.sub.m) and of the calculation result (SRESb.sub.1, . . . , SRESb.sub.m) with respect to the second random number (RNDb.sub.1, . . . , RNDb.sub.m), sent from the mobile station.
    • 在初步认证阶段,通过从家庭网络(30)向漫游网络(31)发送多对第一随机数(RNDa1,...,RNDan)和计算来对移动台(35)进行认证 使用密钥(ki)和第一随机数(RNDa1,...,RNDan)在家庭网络中执行计算的密码函数(f)的结果(SRESa1,...,SRESan),通过发送 从漫游网络到移动台,通过将在漫游网络产生的第二随机数(RNDb1,...,RNDbm)与第一随机数(RNDa1,...,RNDan)相耦合而形成的第三随机数,通过发送 ,从移动站到漫游网络,计算结果(SRESa1,...,SRESan,SRESb1,...,SRESbm)),该密码函数(f)在移动站使用密钥执行计算 (ki)和发送的第三个随机数,并通过在漫游网络上确认计算结果的一致性 lts(SRESa1,。 。 。 ,SRESan)从移动台发送来自家庭网络的计算结果(SRESa1,...,SRESan)。 在主认证中,通过使用一对第二随机数(RNDb1,...,RNDbm)和计算结果(SRESb1,...,SRESbm)对第二随机数( RNDb1,...,RNDbm),从移动台发送。

    • A mobile communication system includes a first and second systems. Each of the first and second systems has a land station and at least one mobile terminal capable of communicating with the land station. The land station of the first system has a broadcasting channel transmission unit for transmitting status information via a broadcasting channel, and the mobile terminal of the second system has a broadcasting channel receiving unit for receiving information in the broadcasting channel to obtain a broadcasting channel receiving condition and the status information, a giving interference estimation unit for estimating giving interference level onto communication of the first system by the second system based upon the obtained broadcasting channel receiving condition and the obtained status information, and an output signal level control unit for controlling output signal level of the mobile terminal of the second system based upon the estimated giving interference level.
