    摘要: A receiver in a wireless communication system detects a possibly interfering radar signal, and uses dynamic frequency selection to switch to a non-interfering channel. The power level and the channel of the radar signal may be detected. When a radar signal that exceeds a predetermined power level is detected, the receiver may be tuned until the channel of the radar signal matches the communication receiver channel. The communication receiver may then be tuned to a higher quality channel to mitigate or avoid interference between communication signals and the radar signal.

    摘要: Embodiments of the present invention disclose a service processing method, a communication device, and a communication system. The service processing method includes: receiving a request message initiated by a user equipment (UE); and changing a current default bearer of the UE according to the received request message, to a bearer corresponding to a service that the UE needs to obtain in a current serving cell. The communication device includes: a generating unit, configured to generate a request message, where the request message carries information indicating a service required by the UE; and a sending unit, configured to send the request message generated by the generating unit to a network side, where the network side changes a current default bearer of the UE according to the information carried in the request message, to a bearer corresponding to a service that the UE needs to obtain in a current serving cell. According to the technical solution disclosed in the embodiments of the present invention, the UE can obtain the required service when moving between different serving cells.
