    • Apparatus, and an associated method, for requesting a measurement to be performed at a communication station of a radio communication system, such as a WLAN. A measurement request message is generated at a requesting station. The measurement request message includes fields identifying a selected measurement type and a field identifying a duration period for which the measurement is requested to be made. The duration period is mandatory or non-mandatory. The request message is communicated to a communication station whereat the message is detected and the values contained therein are identified. Selection is made at the communication station to which the message is delivered whether to perform the requested measurement for the requested duration period. If the requested duration period is non-mandatory, the communication station is able to select a duration period of lesser length during which to perform the requested measurement.
    • 用于请求在诸如WLAN的无线电通信系统的通信站处执行测量的设备和相关方法。 在请求站产生测量请求消息。 测量请求消息包括标识所选择的测量类型的字段和标识要求进行测量的持续时间段的字段。 持续期是强制性的或非强制性的。 请求消息被传送到通信站,在那里检测到消息,并且识别出其中包含的值。 在发送消息的通信站进行选择是否对所请求的持续时间段执行所请求的测量。 如果请求的持续时间段是非强制性的,则通信站能够选择执行所请求测量的较短长度的持续时间段。

    • The invention provides a method of providing secure data communication between a client device and a network device, wherein the method comprises arranging a periodically varying broadcast code (N) to be transmitted such that the network and client devices have knowledge of the broadcast code (N), providing the network and client devices each with the same secret key code (K) and encryption/decryption algorithm, wherein the algorithm is arranged to encrypt and decipher a encrypted transmission data code used for network authentic data transmissions between the client and network devices, and wherein the encrypted data code is generated from a combination of the data and a secret key (X) which is itself derived from a combination of the secret key code (K) and broadcast code (N). One embodiment provides that the broadcast code (N) is transmitted on request by a network/client device. Another embodiment provides that the ACK frame of a data transmission between client/network devices is used to send notifications of the fact that the broadcast code (N) has changed.
    • 本发明提供了一种在客户端设备和网络设备之间提供安全数据通信的方法,其中该方法包括安排要发送的周期性变化的广播代码(N),使得网络和客户端设备具有广播代码(N ),为网络和客户端设备提供相同的密钥密码(K)和加密/解密算法,其中该算法被安排为加密和解密用于客户端和网络设备之间的网络真实数据传输的加密传输数据代码 ,并且其中所述加密数据代码是从数据和秘密密钥(X)的组合产生的,秘密密钥本身是从秘密密钥码(K)和广播代码(N)的组合导出的。 一个实施例规定,广播代码(N)是由网络/客户端设备根据请求发送的。 另一实施例规定,客户机/网络设备之间的数据传输的ACK帧用于发送广播代码(N)已经改变的事实的通知。
