提出了LTE与CDMA数据业务互操作和语音业务互操作的方案。首先介绍了LTE与CDMA数据互操作的非优化切换和优切换化方案,进而对比了LTE与CDMA语音互操作的SVLTE、CSFB和SRVCC等3种方案,其中SVLTE方案相对较为成熟,能够做到语音和数据业务性能互不影响,用户感受最好,而且不需要网络的改动。因此SVLTE是LTE建设初期的优选方案。 Proposed LTE and CDMA data service interoperability and voice service interoperability program. Firstly, the non-optimized handover and excellent handover scheme of interoperation between LTE and CDMA data are introduced, and then three schemes of SVLTE, CSFB and SRVCC for interoperability between LTE and CDMA are compared. The SVLTE scheme is relatively mature and capable of voice And data services do not affect each other, the user experience the best, but does not require network changes. Therefore, SVLTE is the preferred solution in the early stage of LTE construction.
