A propagated control channel signal for use in a shared radio access
network is disclosed. The control channel signal comprises common control
data for use by mobile terminals authorized to access the shared radio
access network and operator-specific data for use by those of the mobile
terminals that are associated with a first mobile operator. The common
control data may comprise handover-related data for handovers within the
shared radio access network and the operator-specific data may comprise
handover-related data for handovers from the shared radio access network
to an unshared radio access network having overlapping coverage with the
shared radio access network. The common control data and the
operator-specific data may comprise values for one or more mobile
terminal settings, wherein the operator-specific values are for use
instead of the common values by those of the mobile terminals that are
associated with the first mobile operator. Methods and apparatus for
using and generating the disclosed propagated control channel signals are
also disclosed.
