a secondary base station adding method based on the strongest measuring level mainly judges according to the level of adjacent cells reported by users, and selects the cell with the strongest level as a secondary base station. The method has certain defects and limitations, only level values are considered in the adding process of the auxiliary base station, the level values cannot reflect the most reasonable cells of the user traveling direction, and the strongest level is not necessarily the most reasonable cell in the moving process of the NSA terminal user, so that the adding of redundant auxiliary base stations is caused, and unnecessary switching and signaling expenses are increased.
The method is mainly characterized in that the auxiliary base station is added according to anchor points occupied by NSA terminal users and anchor point co-coverage sectors. The method has certain defects and limitations, and a user is moving, so that a common coverage site is not necessarily a cell with the most reasonable traveling direction, and a subsequent service is added, and a base-auxiliary base station is deleted again and selected, so that redundant auxiliary base station addition is performed for many times, and the perception of a client is influenced.

When the terminal carries out continuous cell switching, the terminal is switched from a target cell m to a first cell s and is switched from the first cell s to a second cell j, and the base station of the first cell s is added as an auxiliary base station, namely the terminal is althoughThe switching is carried out twice, but only one auxiliary base station needs to be added, the time for a user to occupy the auxiliary base station is longest, the pilot frequency measurement is reduced, the rate loss is reduced, the auxiliary base station in the advancing direction is added at the maximum probability, the unnecessary switching times and the signaling overhead are reduced, and the rapidity of adding the auxiliary base station is ensured.

the second probability is the probability of the terminal performing single cell switching;
the terminal carries out cell single switching, which comprises the following steps: the terminal is handed over from the target cell to the first cell.
Specifically, on the basis of the above embodiment, if none of the first cells corresponding to the first probabilities satisfies the preset condition, that is, none of the first cells corresponding to the first probabilities have co-sited 5G sites, step S210 is executed.

That is, the first cell s corresponding to the second probability has co-sited 5G sites, and the 5G site of the cell is a traveling-direction site. The terminal carries out cell single switching, switches from a target cell m to a first cell s, adds a base station of the first cell s as an auxiliary base station, adds the auxiliary base station in the traveling direction with the maximum probability, and ensures the most smooth addition of the auxiliary base station and the stability of the addition of the auxiliary base station. The maximum possible handover cell decider is configured to calculate a decision of the maximum possible handover cell under discontinuous handover.
