    • There is provided a mechanism for controlling communications conducted via different frequency bands or communication spectrums. When a communication via a first communication path, for example an unlicensed or white space communication spectrum, is to be established, e.g. for offloading traffic from a second communication path, for example a licensed cellular communication spectrum, a preamble transmission command is generated and transmitted from a communication network control element, such as an eNB, via the second communication path to a communication element, such as a UE. By means of the preamble transmission command, the transmission of a preamble signal by the receiving communication element on the first communication path with predetermined communication resources is triggered. Based on a receipt or non-receipt of the preamble signal via the first communication path, the communication network control element is able to determine that the communication element can establish a connection on the first communication path, for example the unlicensed or white space communication spectrum.
    • 提供了用于控制经由不同频带或通信频谱进行通信的机制。 当通过第一通信路径进行通信时,例如未许可或白空间通信频谱,将被建立,例如, 为了从第二通信路径(例如许可的蜂窝通信频谱)卸载业务,生成前导发送命令,并且经由第二通信路径从诸如eNB的通信网络控制元件发送到通信元件,诸如 UE。 借助于前导码传输命令,触发由具有预定通信资源的第一通信路径上的接收通信元件的前导码信号的传输。 基于经由第一通信路径的前导信号的接收或不接收,通信网络控制元件能够确定通信元件可以在第一通信路径上建立连接,例如,未许可或白空间通信频谱 。
