At the 3GPP TSG RAN #61 meeting, the Study Item description on "Study on Smart Congestion Mitigation in E-UTRAN" was approved [2]. This study covers improvement of congestion mitigation handling mechanisms in RRC_IDLE, in order to ensure prioritization of access for initiation of MMTEL voice calls, depending on the operator scenario.

The present document is related to the technical report for the study item "Study on Smart Congestion Mitigation in E-UTRAN" [2]. This activity involves the Radio Access work area of the 3GPP studies and has impacts both on the Mobile Equipment and Access Network of the 3GPP systems. This document is intended to gather all technical outcome of the study item, and draw a conclusion on way forward.
