    • A radio access device includes a controller signal processing unit (RNSAP unit) that processes a signal exchanged with a radio network controller (RNC); and a switching center signal processing unit (RANAP unit) that processes a signal exchanged with a switching center. The RNSAP unit requests to establish a communication path between the radio access device and the RNC and a communication path between the RNC and a BTS by transmitting a request signal to the RNC. Subsequent to receiving an acknowledgement signal corresponding to the request signal from the RNC, the RANAP unit requests to establish a communication path between the switching center and the RNC. Subsequent to receiving, by the RANAP unit, an acknowledgement signal corresponding to the request signal from the switching center, a communication path between the radio access device and the UE is released.
    • 无线电接入设备包括处理与无线电网络控制器(RNC)交换的信号的控制器信号处理单元(RNSAP单元); 以及处理与交换中心交换的信号的交换中心信号处理单元(RANAP单元)。 RNSAP单元通过向RNC发送请求信号来请求建立无线接入设备与RNC之间的通信路径以及RNC与BTS之间的通信路径。 在从RNC接收到与请求信号相对应的确认信号之后,RANAP单元请求建立交换中心与RNC之间的通信路径。 在由RANAP单元接收到与来自交换中心的请求信号相对应的确认信号之后,释放无线接入设备与UE之间的通信路径。
