At the initial stage of LTE network deployment, the users’ perception and experience wil be influenced by the deficiency of network coverage. By adopting the interoperation solutions of the data service between LTE and 3G under the condition of imperfect coverage of LTE, the users’ smooth handoff between 4G and 3G networks can be guaranteed. Starting from the research on the C/L interoperation theory, the article has an exploration on the theory-realization, interactive process and classification of the C/L interoperation.
