    • A mobile station can be authenticated by, for example, sending a challenge to a mobile station, and receiving a first authentication response from the mobile station through a wireless link, the first authentication response being generated based on the challenge and an authentication key stored at the mobile station. A second authentication response is generated based on the first authentication response. The second authentication response is provided to an IMS network for authenticating the mobile station to enable the mobile station to access the IMS network. In some examples, an authentication response of the mobile station is carried in an SIP message sent from the femtocell to a server that can authenticate the mobile station or forward the authentication response to another server that can authenticate the mobile station. Authentication of the mobile station can be performed as an integrated part of or separate from a registration process.
    • 移动台可以通过例如向移动台发送挑战以及通过无线链路从移动台接收第一认证响应来进行认证,所述第一认证响应是基于挑战生成的,以及存储在 移动台。 基于第一认证响应生成第二认证响应。 将第二认证响应提供给IMS网络,用于认证移动台以使移动台能够访问IMS网络。 在一些示例中,移动站的认证响应在从毫微微小区发送到可以认证移动台的服务器的SIP消息中携带,或者将认证响应转发给可以认证移动站的另一个服务器。 移动台的认证可以作为注册过程的集成部分或与注册过程分离来执行。
