Abstract: A method for reserving and allocating resources for an ultra-low-latency uplink service flow based on an air interface slice includes: virtualizing an air interface resource of a base station side into an ultra-low-latency slice resource and a non-ultra-low-latency slice resource; recording a collision situation on reserved resources in each retry window, and dynamically adjusting a size of the reserved ultra-low-latency slice resource; after detecting that a terminal transmits ultra-low-latency data on the ultra-low-latency slice resource, performing a resource reallocation and determining whether an idle resource is presented; if presented, allocating the idle resource to the terminal transmitting the ultra-low-latency data and returning the borrowed non-ultra-low-latency slice resource after transmitting the ultra-low-latency data; and if not presented, borrowing the non-ultra-low-latency slice resource allocated to a non-ultra-low-latency terminal and returning the borrowed non-ultra-low-latency slice resource after transmitting the ultra-low-latency data.
