    • A network controller operates in an unlicensed wireless communication system including a first radio access network. The network controller includes a Up interface for communicating with a mobile station and an IP network interface. The network controller includes a network interface for connecting the network controller to a UMTS core network that is accessible to a second radio access network that includes a UTRAN. The network interface includes an Iu-CS interface to communicate with a MSC in the UMTS core network. The network interface supports signaling protocols for circuit-switched services while inter-working with the UMTS core network via the Iu-CS interface using a layered protocol that includes a RANAP layer over a SCCP layer and several Iu-CS control plane lower layers. The network controller includes modules for generating and/or processing messages transmitted over the network interface. The network controller appears to the UMTS core network as a UTRAN RNC.
    • 网络控制器在包括第一无线电接入网络的未许可无线通信系统中操作。 网络控制器包括用于与移动台通信的Up接口和IP网络接口。 网络控制器包括用于将网络控制器连接到可包括UTRAN的第二无线电接入网络可访问的UMTS核心网络的网络接口。 该网络接口包括用于与UMTS核心网络中的MSC进行通信的Iu-CS接口。 该网络接口支持用于电路交换业务的信令协议,同时通过Iu-CS接口与UMTS核心网络相互作用,该分层协议包括SCCP层上的RANAP层和多个Iu-CS控制层下层。 网络控制器包括用于生成和/或处理通过网络接口发送的消息的模块。 网络控制器作为UTRAN RNC出现在UMTS核心网络中。
