Abstract: Embodiments of this application provide a communication method, an apparatus, and a system. In this solution, after determining that a connection failure occurs, a terminal device records and sends a first report. The first report includes cell information of a first logical cell, or the first report includes a PLMN identifier of a first logical cell and cell information of a second logical cell. The first logical cell includes a source logical cell and/or a failed logical cell in which the connection failure occurs. The second logical cell includes a 1st logical cell that shares a same physical cell with the source logical cell and/or a 1st logical cell that shares a same physical cell with the failed logical cell. Based on this, a connection failure rate of the terminal device in a RAN sharing scenario can be reduced, and a handover success rate can be improved.
