About the issue 'whether and how using WUS may affect MME paging strategies' in R15, regarding the solution in SA WG2 approved TS 23.401 CR 3582 release 15, RAN WG3 detected some issues and would like to provide following feedback: - It is assumed by many companies that the MME is not able to interpret the UE Radio Capability for Paging IE as it is encoded as RRC container. - There is no agreement in RAN WG3 to inform the eNB WUS supporting to MME in S1 SETUP REQUEST and ENB CONFIGURATION UPDATE messages. - The Assistance Data for Recommended Cells is now defined as transparent to EPC, besides this information, the MME is also able to get the last cell info from the received User Location Information IE and the Cell Identifier and Coverage Enhancement Level IE. RAN WG3 will further discuss how to address these and update the solution in next meeting. Action: RAN WG3 kindly asks SA WG2 to take above feedback into account.","secretary_remarks":"Responses drafted in S2-2002885 and S2-2002897.
