CSFB Success Rate Based Handover (LTE to CDMA2000)

Description

The CSFB Success Rate Based Handover (LTE to CDMA2000) KPI indicates the success rate of handover-based LTE-to-CDMA2000 CSFB.
The number of handover-based LTE-to-CDMA2000 CSFB attempts increases by 1 at point B as shown in Figure 1 after the eNodeB sends a Mobility From EUTRA Command message to the UE and performs CSFB to a CDMA2000 network. The number of successful handover-based LTE-to-CDMA2000 CSFB executions increases by 1 at point C, where the eNodeB receives a UE CONTEXT RELEASE COMMAND message from the MME after the UE successfully accesses the CDMA2000 network.

Definition

The CSFB Success Rate Based Handover (LTE to CDMA2000) KPI is defined in Table 1. The number of handover-based LTE-to-CDMA2000 CSFB attempts and the number of successful handover-based LTE-to-CDMA2000 CSFB executions are collected as described in Description.
