SA WG2 acknowledges that the PARLOS feature in Rel-16 is related to E-UTRA\/EPC. SA WG2 would like to provide further clarifications to the following statement: - Addition of RRC establishment cause for RLOS for congestion control and MME selection. TSG RAN noted that the number of spare cause value and spare bits in LTE connection set up procedure is very limited and thus more discussion would be required in RAN WG2 to fully answer the feasibility of adding additional information. There was no support to use the remaining spare bits for this feature. SA WG2 understands that the number of spare cause values in the E-UTRA RRC connection establishment request is limited. SA WG2's intention is to inform the E-UTRAN (e.g. eNB) that the RRC connection establishment procedure is for RLOS, so that E-UTRAN can apply congestion control and\/or MME selection accordingly.

SA WG2 has discussed the following alternative NAS based solution for informing the E-UTRAN that the access is for RLOS and has asked for feedback: 2) During the RRC connection establishment procedure, the UE uses a special decorated S-TMSI\/M-TMSI (or a reserved S-TMSI\/M-TMSI bit sequence) in the InitialUE-Identity information element. It means that this S-TMSI\/M-TMSI is not derived from GUTI even if GUTI is available in the UE. At the NAS level, the UE includes the GUTI (if available) in the NAS message. The impacts of this alternative (including Service Request procedure, MME selection in case of UE context already existing in CN, etc.) have to be studied. CT WG1 discussed the alternative NAS based solution and would like to provide the following feedback. The NAS based solution is feasible from a CT WG1 point of view.
