The enhanced Multi-Level Precedence and Pre-emption (eMLPP) fea-
ture enables the operator to give high priority users good access to
the network. This is achieved by means of removing connections of
low priority users from a congested cell required by a high priority
connection. Up to two attempts to hand over a low priority connection
to another cell is made. If the handovers fail the low priority
connection is disconnected.
