This invention discloses an IC phone communication method based on the FSK mode including: loading and transmitting ciphered sequences, ciphered card information, called number information and other interaction information between an IC terminal and a process platform in the mode of FSK information, in which, the platform authenticates the authority and charges, if the deduction at the IC terminal is correct, then it sends signals of anti-stealing making phone calls periodically to the platform, which differentiates the correctness of the signals, if they are wrong, it releases the call, when the communication is finished and the calling rings off first, the platform receives the identification signals of the ring-off of the calling to cut off the call of the called side and release the voice channel between the platform and the called side, then processes balance information and releases the call finally.

本发明公开了一种基于频移键控方式的IC卡电话通信方法，其主要方案是IC卡终端与处理平台之间通过FSK信息方式承载和传输加密序列、加密卡信息、被叫号码信息及其它交互的信息，由处理平台进行鉴权和计费；如果IC卡终端扣费正确则周期性向处理平台发送防盗打信号，处理平台鉴别防盗打信号的正确性，如果错误则释放呼叫；当通信结束后主叫先挂机时，处理平台收到主叫挂机标识信号后首先切断被叫侧的呼叫，释放处理平台与被叫侧之间的话路，然后再进行余额信息的处理和最后释放呼叫。使用本发明提出的方法，使得IC卡终端与处理平台之间的信息交互流程更加简单、清晰，提高了信息交互效率，并能及时释放话路，节约中继资源。

D. This command is required for all Frame Relay configurations.E. The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC.

因为在默认的情况下，帧中继的网络为非广播的，而 RIP 在其上是无法发包的。

However, DAF requires the relay to have the likelihood-ratio distribution, typically modeled as a Gaussian mixture.

然而，解码放大转送模式的中继端需要知道Log-Likelihood Ratio的分布，一般被模拟成高斯混合。

In the opener against Seattle, 50,724 fans participated in a gimmick associated with the dance craze of the moment by forming the largest Macarena line ever, and then watched as Dave Pavlas, Bob Wickman and Jeff Nelson could not do Rivera's job, allowing three runs in a 6-5 Seattle win.

然而牛棚投手Dave Pavlas， Bob Wickman 和Jeff Nelson都无法做好原本Mo的中继角色，丢了3分让水手以6-5赢球。

Reliability in the Internet is achieved through the use of acknowledgments and retransmissions.

网络中的可靠性是通过安全证书和中继达到的。

When the relay is more than 3 layers, the calculation job of concentrators increase a lot.

当中继参数超过3级，集中器的计算量，呈几何级数上升。

Dr Shields's photon detector, however, permits cryptographers to use a phenomenon called quantum entanglement to make a repeater that does not destroy quantum states.

史立德博士的光子探测器允许密码器利用一种叫量子纠结的现象来建立中继器，而又不破坏量子形态。
