Inter-Frequency Handover Out Success Rate -- LTE

Inter-Frequency Handover Out Success Rate

Description

The Inter-Frequency Handover Out Success Rate KPI indicates the success rate of inter-frequency handovers (HOs) from the local cell to neighboring E-UTRAN cells. The measurement methods of the related counters are similar to those for intra-frequency HOs described in Intra-Frequency Handover Out Success Rate > Description. The only difference is that the source and target cells operate on different frequencies and both work in FDD or TDD mode.

Figure 1 and Figure 2 illustrate intra-eNodeB HOs, and the source and target cells operate on different frequencies. The source eNodeB counts the number of intra-eNodeB inter-frequency outgoing HO execution attempts in the source cell at point B and counts the number of successful intra-eNodeB inter-frequency HO executions in the source cell at point C. Figure 3, Figure 4, Figure 5, Figure 6, Figure 7, and Figure 8 illustrate inter-eNodeB HOs, and the source and target cells operate on different frequencies. The source eNodeB counts the number of inter-eNodeB inter-frequency outgoing HO execution attempts in the source cell at point B and counts the number of successful inter-eNodeB inter-frequency HO executions in the source cell at point C.
 

Definition

The Inter-Frequency Handover Out Success Rate KPI is defined in Table 1. Note that the number of outgoing HO execution attempts and the number of successful outgoing HO executions are collected based on the description in Description.
