Octet 5 indicates if WLAN Offload has been authorized for the UE:
– Bit 8 to 3 Spare, for future use and set to zero.
– Bit 2 – reflects the information available at the UE regarding E-UTRAN Offloadability. When set to ‘1’, this indicates that the UE has been authorized to perform WLAN offload from E-UTRAN. When set to ‘0’, this indicates that the UE has not been authorized to perform WLAN offload from E-UTRAN.
– Bit 1 – reflects the information available at the UE regarding UTRAN Offloadability. When set to ‘1’, this indicates that the UE has been authorized to perform WLAN offload from UTRAN. When set to ‘0’, this indicates that the UE has not been authorized to perform WLAN offload from UTRAN.
