In mission critical networks ensuring the ability of Public Safety officers to communicate is of the utmost importance. Isolated E-UTRAN Operation seeks to enhance the ability of Public Safety officers to communicate by investigating improved support for situations where users move out of E-UTRAN coverage or following the loss of backhaul communications.
This TR studies use cases and identifies potential requirements for Isolated E-UTRAN Operation in support of mission critical network operation for Public Safety.
