    • A method for a terminal including a first media access control (MAC) layer and a second MAC layer to create an authorization key includes performing a first network entry process to a base station through the first MAC layer, and performing a second network entry process for a frequency overlay to the base station through the second MAC layer. In this instance, the first network entry process includes acquiring a key for generating an authorization key through an authentication process according to an authentication method negotiated with the base station, and generating a first authorization key through the key for generating the authorization key. The second network entry process includes generating a second authorization key by using the key generated in the first network entry process for generating the authorization key.
    • 一种包括第一媒体接入控制(MAC)层和第二MAC层以创建授权密钥的终端的方法包括:通过第一MAC层对基站执行第一网络进入过程,并且执行第二网络进入处理, 通过第二MAC层对基站的频率覆盖。 在这种情况下,第一网络进入处理包括通过根据与基站协商的认证方法的认证处理来获取用于生成授权密钥的密钥,以及通过用于生成授权密钥的密钥生成第一授权密钥。 第二网络进入处理包括通过使用在第一网络进入处理中生成的密钥来生成授权密钥来产生第二授权密钥。
