The embodiment of the invention provides a multi-air-interface communication method and apparatus. In the method, a mobile terminal supports a variety of air interfaces, and by adoption of the method,a buffer status report (BSR) sending problem, a power headroom report (PHR) reporting problem and a discontinuous reception (DRX) problem in the case of multiple air interfaces are solved. By adoption of the solution of the BSR sending problem in the case of multiple air interfaces, a base station can allocate wireless resources to the mobile terminal more accurately based on the BSRs sent by themobile terminal on the air interfaces. By adoption of the solution of the PHR reporting problem in the case of multiple air interfaces, the base station can allocate wireless resources to the mobileterminal more accurately. The solution of the DRX problem in the case of multiple air interfaces is more conductive to saving the power of the mobile terminal.
