摘　　要：LTE网络的CSFB方案主要选择回落到GSM网络,但现网存在着局部场景更适合选择回落到TD-SCDMA网络的情况。为此,中山移动在现网开展了TD-LTE CSFB回落到TD-SCDMA的可行性测试,并结合测试探讨了更适合回落到TD-SCDMA的若干场景。CSFB in LTE network mainly falls back to GSM network. However, some local scenarios in existing network are more suitable for falling back to TD-SCDMA network. Therefore, Zhongshan Mobile deployed feasibility tests on TD-LTE CSFB falling back to TD-SCDMA; combined with tests, several scenarios suitable to fall back to TDSCDMA network were discussed.
