Due to the limitation of the transmission power and the coverage of the ordinary small base station or the terminal type base station, the terminal type base station can only listen to the wireless parameter configuration information of the small cell that overlaps with its own terminal small cell. Taking FIG. 1 as an example, it is assumed that three small cells are deployed under the macro base station 12, and the terminalized small cells 141 of the terminal type base station 14 are used. The small cell 131 and the terminal small cell 151 are overlapped, and the small cell that the terminal base station 14 can monitor is the normal small cell 131 and the terminal small cell 151, and the small cell that the ordinary small base station 13 can monitor is the terminal small cell 141. The small cell that the terminal type base station 15 can monitor is the normal small cell 13. After the wireless parameter configuration information of the small cell monitored by the terminal type base station, the wireless parameter configuration information of the small cell whose working frequency band is the unlicensed spectrum is filtered according to the frequency range of the unlicensed spectrum, and the wireless parameter configuration information may include the physical cell identifier and the maximum transmission. Power, frequency and tracking area code.

S202. The terminal type base station acquires location information.

Specifically, the terminal type base station acquires its own location information, and the location information may be absolute location information, such as latitude and longitude of the current location, or may be relative location information, such as acquired received signal strengths of at least three small base stations, according to at least three The received signal strength of the base station can be used to know the relative positional relationship between the terminal type base station and the three small base stations.

S203. The terminal type base station sends a cell configuration request message.
