A method of supporting reverse channel gating in a BS (Base Station) of a
mobile communication system. At a handoff from a first BS to a second BS,
the first BS transmits to the second BS information about whether an MS
(Mobile Station) transmits data on the channel to the first BS in a
reverse gating mode. The second BS determines whether to support the
reverse gating mode after the handoff. Then the second BS transmits to
the first base station a handoff request acknowledgement message
including information whether the second BS supports the reverse gating
mode after the handoff.
