Specifically, when the terminal base station needs to enable the small base station function, it monitors the wireless parameter configuration information of the surrounding small cells in the unlicensed spectrum. The small cells in the unlicensed spectrum are small cells within the coverage of the macro cell of the macro base station. The small cell indicating that the working frequency band or frequency point is an unlicensed spectrum may be a terminalized small cell of other terminal base stations, or a common small cell of an ordinary small base station. Due to the limitations of transmission power and coverage of ordinary small base stations or terminal base stations, terminal base stations can only monitor wireless parameter configuration information of small cells overlapping with their own terminalized small cells. Taking Fig. 1 as an example, assuming that there are three small cells deployed under the macro base station 12, the terminalized small cell 141 of the terminal base station 14 overlaps with the common small cell 131 and the terminalized small cell 151, and the small cells that the terminal base station 14 can monitor The cells are ordinary small cells 131 and terminalized small cells 151 , the small cells that can be monitored by ordinary small base stations 13 are terminalized small cells 141 , and the small cells that can be monitored by terminal base stations 15 are ordinary small cells 13 . After monitoring the wireless parameter configuration information of the small cell, the terminal base station screens the wireless parameter configuration information of the small cell whose working frequency band is the unlicensed spectrum according to the frequency range of the unlicensed spectrum. The wireless parameter configuration information may include the physical cell ID, the maximum emission Power, frequency point and tracking area code, etc.

S202. The terminal base station acquires location information.

Specifically, the terminal-type base station obtains its own location information. The location information can be absolute location information, such as the latitude and longitude of the current location, or relative location information, such as the received signal strength of at least three small base stations obtained according to at least three The received signal strength of the base station can know the relative position relationship between the terminal base station and the three small base stations.

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

Specifically, the terminal base station sends a cell configuration request message to the network side equipment. The cell configuration request message carries the wireless parameter configuration information of the surrounding unlicensed spectrum small cells monitored by the terminal base station and the location information of the terminal base station. The cell configuration request message It is used to instruct the network side device to allocate cell configuration information for the terminalized small cell of the terminal base station. The cell configuration information may be one or more of physical cell identifier, maximum transmission power, frequency point, and tracking area code.

For example, the network side device allocates physical layer cell identifiers for the terminalized small cells of the terminal base station based on the conflict-free allocation rule and the confusion-free allocation principle. The conflict-free allocation rule means that two adjacent unlicensed spectrum small cells cannot use the same physical Layer cell identification, if the same mobile terminal may not be able to read the PSS and SSS, and thus cannot synchronize with the cell; the non-confusing allocation rule means that two adjacent unlicensed spectrum small cells of the same unlicensed spectrum small cell cannot be allocated the same physical layer cell For example, two adjacent unlicensed spectrum small cells of unlicensed spectrum small cell C are A and B, then unlicensed spectrum small cells A and B cannot be assigned the same physical layer cell identity.

Furthermore, the network side device can also allocate physical layer cell identifiers to the terminalized small cells of the terminal base station based on the allocation rules of space division multiplexing, specifically, the allocation of two small cells with the same frequency distance greater than the preset value With the same physical layer cell ID, two adjacent small cells with different frequency points are assigned the same physical layer cell ID. In the case of a tight number of physical layer cell IDs, the utilization rate of the physical layer cell ID is improved. Among them, space division multiplexing The small cells described in the allocation rules are unlicensed spectrum small cells, and the unlicensed spectrum small cells can be ordinary small cells or terminalized small cells.

It should be noted that the preset value can be set as required, and the present invention is not limited thereto. The physical layer cell identifier may be a physical cell identifier or other identifiers used to uniquely represent the identity information of the cell, which is not limited in the present invention.
