The number of slave base stations may be one or multiple, and the preset distance threshold may be set according to actual needs, which is not specifically limited by the present disclosure.
In the embodiment of the present disclosure, the master base station may be a first base station in the cascaded at least one base station, and only one slave base station may be connected; the first base station may be a non-first base station in the at least one base station, that is, the middle base station in the at least one base station, and the left side and the right side may be connected to a slave base station, respectively.

As shown in fig. 3, fig. 3 is a flowchart illustrating a further base station handover method according to an exemplary embodiment, including the following steps:
step 301, sending the same cell serial number to at least one base station, so that the total coverage area of at least one base station corresponds to the same cell, where at least one base station includes a master base station and a slave base station, the master base station is a current access base station, and the slave base station is an adjacent base station of the master base station.

The base station handover threshold may be defined according to actual needs, and this disclosure is not particularly limited thereto. For example, the deployment density of base stations in a certain area is particularly high, and the base station handover threshold may be set to be relatively low, so that when the difference between the reference signal received power and the reference signal received power of the currently accessed base station meets the base station handover threshold, the terminal device is immediately accessed to the base station corresponding to the reference signal received power, and the situation that the base station handover threshold is set to be too high and a plurality of base stations meet the access requirement is avoided.
