NOTE: Due to a specification oversight, the CMI values in the above table are reversed from the values of the CSG-Membership-Indication AVP in 3GPP TS 32.299 [54], as well as from the values of the CMI in the UCI IE (see clause 8.75). Therefore, when the above CMI values are sent over the charging interface, the values are encoded as specified in 3GPP TS 32.299 [54].
