  • Publication number: 20250185050
    Abstract: In the present invention, a buffer state of a mobile terminal is estimated based on a traffic pattern identified by profiling traffic of the mobile terminal to then preemptively allocate a resource. In order to prevent an allocated radio resource from being wasted, a resource requested through a buffer state report or the like is first allocated, and the remaining resources are preemptively allocated according to the estimated buffer state.
