Abstract

Transferring communication within a communication system occurs as follows: during communication with a serving base station (101), in order to shorten the duration before downlink data can be initiated to a remote unit (113) that has performed cell reselection, an automatic downlink procedure is executed. The auto downlink procedure transfers remote unit related information to a scheduler for appropriate allocation of air interface resources for a remote unit that recently has undergone a cell reselection procedure. When the remote unit reestablishes itself in a target cell (107'), the source packet control unit (107) determines that the cell reselection was successful and selectively transfers radio access capability information to the target packet control unit. The target packet control unit immediately is able to transfer downlink data arriving from the serving GPRS support node (105) to the remote unit without first establishing a downlink temporary block flow, thereby significantly reducing the time required for cell reselection.
