A.LTE inter-frequency switching can only be switched through the S1 interface and cannot be switched through the x2 interface.

B.Frequency-prioritized inter-frequency switching can be triggered based on A1 events or triggered based on A2 events depending on the coverage scenario.

C.LTE inter-frequency handover will send a GAP to the mobile phone for measurement. There are 2 different GAP modes.

D.If the center frequencies of the two cells are the same, but the spectrum bandwidth is different, the switching between the two cells belongs to the inter-frequency handover.
