Abstract: Embodiments of the present application disclose a traffic offloading method and apparatus. The method includes: calculating, by a first network node, a first packet loss rate of a first forwarding tunnel in a preset period; when the first packet loss rate is higher than a first preset threshold, reducing a rated bandwidth of the first forwarding tunnel by a first preset bandwidth, so as to obtain a first available bandwidth; and when traffic forwarded over the first forwarding tunnel exceeds the first available bandwidth, offloading excess to-be-forwarded traffic to the second data link for forwarding. Because the first available bandwidth is less than an original available bandwidth of the first forwarding tunnel, the to-be-forwarded traffic exceeds the first available bandwidth at an earlier time, traffic is offloaded by the first network node in advance, and a serious packet loss is less likely to occur before traffic offloading.

Abstract: Embodiments of the present application provide a method, device and system for controlling an air interface resource and relates to the field of communications, which improves air interface resource utilization. The method includes: when a core network device or user equipment detects that service data is not transmitted over a communication channel between the two devices by using an air interface resource, switching a first frequency of sending a hello packet to a peer device to a second frequency, and sending a frequency switching message to instruct the peer device also to switch the first frequency of sending a hello packet to the second frequency, so that when the hello packet is not detected within a packet detection period, an access network device releases an air interface resource occupied by a first communication channel.
