Rapporteur:  Mr. Yao, Yizhi
The present document studies the following OAM aspects of LWA (for both co-located and non-co-located deployment scenarios) and LWIP, based on the solutions defined by 3GPP RAN WGs:
  • the WLAN related information needs to be configured to the eNB to support LWA and LWIP
  • how the NM/EM of the eNB gets the required WLAN information for the cases that the WLAN nodes are managed by 3GPP or non-3GPP management system
  • the management model for WT for co-located and non-co-located LWA deployment scenarios
  • the performance measurements to monitor the LWA and LWIP
  • the alarm information needs to be enhanced to support FM (Fault Management) for LWA and LWIP
The study also makes conclusions on the preferred solution(s), and provides recommendations for the normative work based on the conclusions of the study.
