Background
The network side can configure the UE to collect and record the measurement result of the local cell/adjacent cell (such as Reference Signal Received Power (RSRP)/Reference Signal Received Quality (RSRQ) and the like), the location information (such as detailed location information of radio frequency fingerprint (RF fingerprint) or Global Positioning System (GPS) location and the like), the cell identification of the local cell and/or adjacent cell, the data packet delay, the log ending time and the like.

Where T0-T represents another time that is prior to the current time and that is separated from the current time by a time period T.
Through the steps, the network equipment of the embodiment of the invention configures the terminal to record the cell reselection information, thereby controlling the terminal to record the cell reselection information and providing reference data for optimizing multi-beam deployment and/or reselection parameters on the network side.
After sending the configuration message to the terminal, the terminal may record the cell reselection information according to the configuration message after the terminal itself enters an idle state or an inactive state.

After receiving the log or the indication information, if the log or the indication information indicates that the terminal has updated the cell reselection information, the network device sends a request message for requesting the cell reselection information of the terminal to the terminal, so that the cell reselection information returned by the terminal according to the request message can be received.
