System and method for identifying an off-channel radio frequency source
In a shared radio frequency (RF) band, regulations or standards can stipulate that a device using an RF channel must vacate the RF channel if another device having priority to the channel is detected. It takes time, however, to move channels and this added time reduces the effective speed of the communication. In some cases, a received signal from the other device may be received on the channel when the other device is not, in fact, operating on the channel. These received signals can lead the device to move channels, thereby slowing communications unnecessarily. Accordingly, disclosed herein are a system and method for checking the characteristics of a received signal's spectrum to determine if the source of the received signal is on-channel or off-channel. This determination may be used to minimize the device from taking unnecessary interference avoidance measures, such as dynamic frequency selection. |

600 MHz spectrum access systems and methods
Systems and methods for utilizing secondary frequency spectrums for increased throughput. When faced with a shortage of primary cellular frequencies, a base station in a cellular network can determine whether secondary frequency spectrum, such as 600 MHz spectrum, frequencies are available. The 600 MHz frequencies can include frequencies licensed to the provider and frequencies licensed to other providers that can nonetheless be used under FCC “Whitespace” rules. Thus, the system can determine whether licensed (“Tier(2)”) or unlicensed (“Tier(3”) 600 MHz frequencies are available. Tier(2) frequencies can essentially be used in the normal manner—e.g., at normal power levels and emissions patterns. Tier(3) frequencies can be used under the Whitespace rules. The system can then provide these 600 MHz frequencies to capable user equipment (UE). The system can also prioritize frequencies based on UE capabilities, location, and other factors. |

An information pushing method reduces the interference to the user and improves the utilization rate of information resources during the process of the information pushing. For example, the server sends the triggering condition in the form of triggering condition information, and the identification information corresponding to the information to be pushed to the client terminal. The client terminal determines whether to push the information to be pushed to the user based on the terminal information on its own and sends the identification information to the server. Then the server sends the information to be pushed to the client terminal according to the identification information so that the client terminal may push the information to be pushed to the user. Alternatively, the server determines whether to push the information to be pushed to the user according to the terminal information, and sends the information to be pushed to the client terminal so that the client terminal pushes the terminal information to the user. |

Local inspection involves identifying potentially suspect packet features based on statistical prevalence of recurring commonalities among the packets; pre-defined threat patterns are not required. For network-wide coherence, each host/NIC uses the same packet-identifying and occurrence-measuring algorithms. An overlay or control server collects and combines the local occurrence-measures to derive the network-wide occurrence-measures. The network-wide occurrences can be used to automatically detect and mitigate completely new types of attack packets. |
