RAN WG3 discussed the respective scenarios, and the associated paging behaviour of the eNB, during RAN WG3#97bis and RAN WG3#98. It is RAN WG3's understanding that the eNB may receive two related IEs within the S1-AP PAGING MESSAGE, specifically: - The UE Radio Capability for Paging IE, which is transparently relayed by the MME and may contain information on UE support of CE modes (or otherwise) - The Assistance Data for CE Capable UEs IE, which contains information on the CE level and last serving cell as reported by the previously serving eNB.

This is feasible and CT WG1 does not see any issue with this Option. - Option 2 will not require any CT WG1 specification changes but will have more system-level impact than Option 1 as it will require adding support for request of ciphering keys by the UE in an MO-LR message, conveying the request from an MME to an E-SMLC, and adding support for the E-SMLC to send the ciphering keys to the UE using LPP.

CT WG4 has discussed the two options considered by SA WG2 for ciphering key distribution to suitably subscribed UEs and would like to convey the following feedback to SA WG2: - Option 1 and Option 2 will have similar specification impacts - Option 2 will have more UE impacts, more MME impacts and more E-SMLC impacts than Option 1 in terms of the procedures that these entities would be required to support and perform - Option 2 will generate additional signalling (since UEs would have to perform an additional MO-LR procedure to obtain ciphering keys) whereas Option 1 will not (since the ciphering keys would be distributed using mobilility management procedures that the UE and network would anyhow need to perform), so Option 2 has more system operation impacts than Option 1 Based on the above comparison, CT WG4 thinks","secretary_remarks":"Reply drafted in S2-182369.
