Step 101: Obtain a first measurement report.

The information identification method described in this embodiment is applied to a device, and the device may be an information identification device; the information identification device may serve as a drive test data mining platform. Here, the first measurement report is a measurement report reported by the user, that is, the device directly obtains the measurement report reported by the user.

Step 102: When the first measurement report carries information representing a handover event and it is determined that handover triggering fails, search for a plurality of second measurement reports within a first time range before obtaining the first measurement report.

Here, the first measurement report carries information representing a handover event, including: when the first measurement report carries a field representing an intra-frequency handover event or an inter-frequency handover event, determining that the first measurement report Carries information that characterizes the switching event.

Wherein, the intra-frequency handover event may be called an A3 event, and the inter-frequency event may be called a B2 event. Then, when the preset field of the first measurement report is set with the character bit representing the A3 event or the character bit representing the B2 event, it is determined that the first measurement report carries information representing the handover event.

In this embodiment, the determining that the handover trigger fails includes: determining that the handover trigger fails when no handover signaling is received within a preset time range after obtaining the first measurement report carrying the information representing the handover event.

Specifically, a preset time after the first measurement report is obtained, and the first measurement report carries information representing a handover event (for example, carrying information representing an A3 event or carrying information representing a B2 event) Within the range (for example, T1 time), when no radio resource control (RRC, Radio Resource Control) reconfiguration message carrying the handover command is received, it is determined that the handover trigger fails.

In this embodiment, when it is determined that the handover trigger fails, search for multiple second measurement reports within the first time range before the first measurement report is obtained, that is, search for the first time before the first measurement report is received Multiple measurement reports for a range (eg T2 time).

In this embodiment, the preset time range (for example, within T1) and the first time range (for example, within T2) may be preconfigured according to actual network conditions or in combination with experience.
