摘要： A method and an apparatus for authentication are disclosed. The method includes: deciding to release a connection or continue a current service according to native information and network policy after an AKA authentication procedure fails. When the EPS AKA authentication procedure fails, the connection is not released immediately in the present invention, but the connection is released or the current service is continued according to the native information and network policy, thus avoiding unnecessary release of connections and saving resources.

摘要： Method, device, and system for deriving keys are provided in the field of mobile communications technologies. The method for deriving keys may be used, for example, in a handover process of a User Equipment (UE) from an Evolved Universal Terrestrial Radio Access Network (EUTRAN) to a Universal Terrestrial Radio Access Network (UTRAN). If a failure occurred in a first handover, the method ensures that the key derived by a source Mobility Management Entity (MME) for a second handover process of the UE is different from the key derived for the first handover process of the UE. This is done by changing input parameters used in the key derivation, so as to prevent the situation in the prior art that once the key used on one Radio Network Controller (RNC) is obtained, the keys on other RNCs can be derived accordingly, thereby enhancing the network security.

摘要翻译：在移动通信技术领域提供了用于导出密钥的方法，设备和系统。用于导出密钥的方法可以用于例如用户设备（UE）从演进的通用陆地无线电接入网络（EUTRAN）到通用陆地无线电接入网络（UTRAN）的切换过程。如果在第一切换中发生故障，则该方法确保由UE的第二切换过程的源移动性管理实体（MME）导出的密钥与针对UE的第一切换过程导出的密钥不同。这是通过改变在密钥推导中使用的输入参数来完成的，以便防止现有技术的情况，一旦获得了在一个无线电网络控制器（RNC）上使用的密钥，则可以相应地导出其他RNC上的密钥，由此增强网络安全。
