TR 23.798 (SA2)
Study on Isolated E-UTRAN Operation for Public Safety –

ToC      3GPP‑Page      Help       
V15.0.0 (Wzip)    2017/06    19 p.

Rapporteur:  Mr. Mouquet, Antoine
See also:  IOPS-related TS/TR    

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 operation; or
  • 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.
