    • The present invention relates to a method, terminal device, network element, authentication server, and computer-readable medium for controlling prioritized access to a wireless access network. An identifier portion in an authentication response is set to a service-specific unique default identifier portion, dedicated to a predetermined prioritized call, at a terminal device, when the predetermined prioritized call is activated. The authentication response is forwarded to a predetermined default authentication server where a predetermined default service-specific authentication method is initiated for authorizing the terminal device to access the predetermined prioritized service. Thereby, emergency calls or services are made by terminal devices without SIM or USIM, and no new authentication functionality related to prioritized calls is required due to the transparent character of the service-specific unique default identifier portion.
    • 本发明涉及一种用于控制对无线接入网络的优先接入的方法,终端设备,网络元件,认证服务器和计算机可读介质。 当预定的优先呼叫被激活时,认证响应中的标识符部分被设置为在终端设备处专用于预定的优先呼叫的特定服务的唯一默认标识符部分。 认证响应被转发到预定的默认认证服务器,其中启动预定的默认服务特定认证方法以授权终端设备访问预定的优先级服务。 因此,紧急呼叫或服务由没有SIM或USIM的终端设备进行,并且由于服务专用唯一默认标识符部分的透明特征,不需要与优先呼叫相关的新认证功能。
