The present document studies potential enhancements to the "Isolated E-UTRAN Operation for Public Safety" feature
specified in TS 23.401
Whereas this feature assumes a complete absence of backhaul, the present study considers following cases:
the backhaul is not completely lost but suffers from a limited bandwidth, which does not suffice for normal
the backhaul is completely lost and a backup link is set up (by means outside the scope of this study) to provide
backhaul with a limited bandwidth as above.
Under such scenario it is desirable to use the available backhaul for signalling between an E-UTRAN site and other
PLMN entities, for local mission critical communications. The present document studies enhancements to realize this in
an optimal manner.
