摘要： Common authentication and authorization (AA) between networks having disparate access technologies may enable a seamless user transition between the networks. A set of AA credentials from a user attempting to gain access to one of the networks may be received, and a subscriber database of another of the networks may be used to verify the set of AA credentials. A communication protocol common to the networks may be used. Additionally, the user may employ a single set of authentication and authorization (AA) credentials, usable over multiple communication protocol layers. Further, a user may perform a single authentication and authorization (AA) operation when roaming across two or more networks by gathering user's key material during an AA challenge and reply session at a data link layer. The gathered material may be used for an AA challenge at an upper network layer or another network as the user transitions between networks.
摘要翻译：具有不同接入技术的网络之间的通用认证和授权（AA）可以实现网络之间无缝的用户转换。可以接收到来自尝试访问其中一个网络的用户的一组AA凭证，并且可以使用另一个网络的订户数据库来验证该组AA凭证。可以使用网络通用的通信协议。另外，用户可以采用可以在多个通信协议层上使用的一组认证和授权（AA）证书。此外，当在数据链路层的AA挑战和应答会话期间收集用户的密钥材料时，用户可以在两个或更多个网络上漫游时执行单个认证和授权（AA）操作。当用户在网络之间转换时，所收集的材料可以用于上网络层或另一网络处的AA质询。
