Abstract
A method of reducing loading on backhaul communications links in a wireless communications system suppresses a portion of the upward flow of frame information for idle and/or erased frames in certain situations, such as when multiple ones of such frames are successively encountered. A radio base station abstains from sending a frame header to a BSC/ANC for second and following frames of the Idle type and/or the radio base station abstains from sending a frame header to a BSC/ANC for second and following frames of the Erased type. The header may also or alternatively be suppressed for an Idle frame immediately following a Good frame. The BSC/ANC in effect fills in the suppressed frame information in such situations, forwards appropriate indications of frame type to the frame selection algorithm.
