| Abstract: |
| Four mechanisms for realizing radio level integration of long term evolution（LTE）system and wireless local area network（WLAN）are summarized. Based on analysis of the deficiencies of traditional integration at core network level,the standardization process of radio level integration in 3GPP Release 12 and 13 is introduced. The effect of each mechanism on user equipment,evolved Node B（eNodeB）and WLAN is discussed as well as their characteristics,merits and application scenarios,which provides a thought for operators to deploy their integrated LTE/WLAN networks. |
| Key words: long term evolution（LTE） wireless local area network（WLAN） radio level integration interworking aggregation |
