A communication system transitions from a high velocity mode of operation
to a non-high velocity mode of operation based on a movement of a mobile
station. When the communication system is in a high velocity mode of
operation, the communication system promotes pilots from a High Velocity
Neighbor Set of the mobile station or a controller. When the
communication system is in a non-high velocity mode of operation, the
communication system promotes pilots from a Neighbor Set of the mobile
station or the controller. The communication system may further include a
high velocity repeater that, when co-located with the mobile station, is
capable of providing a communication link between the mobile station and
a radio access network servicing the mobile station.
