The corresponding terminal small cell is a licensed spectrum small cell, and the macro cell where the terminal type base station is located also works in the licensed spectrum, and the method includes:

S201. Monitor wireless parameter configuration information of the surrounding licensed small cell and the macro cell.

Specifically, the terminal type base station resides in the macro cell and the authorized spectrum of the macro cell operation; when the terminal type base station needs to enable the small base station function, the terminal parameter base station monitors the wireless parameter configuration information of the surrounding licensed spectrum small cell, and the licensed spectrum small cell is the macro base station. A small cell in the coverage of the macro cell, the small cell in the licensed spectrum indicates that the working frequency band or the frequency point is a small cell of the licensed spectrum, and the authorized spectrum small cell may be a terminal small cell of another terminal type base station, or may be a common small base station. Small cell. 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, assume that the macro of the macro base station 12 Three small cells are deployed in the cell 121, and the terminal small cell 141 of the terminal type base station 14 overlaps with the normal small cell 131 and the terminal small cell 151. The small cell that the terminal type base station 14 can monitor is the ordinary small cell 131 and the terminal. The small cell 151, the small cell that the ordinary small base station 13 can listen to is the terminal small cell 141, and 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 in which the working frequency band is the licensed spectrum is filtered according to the frequency range of the licensed spectrum, and the wireless parameter configuration of the macro cell 121 where the terminal base station is located is monitored. The information, the wireless parameter configuration information may include a physical cell identifier, a maximum transmit power, a frequency point, and a 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 obtain the relative positional relationship between the terminal type base station and the at least three small base stations.

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

Specifically, the terminal type base station sends a cell configuration request message to the network side device, where the cell configuration request message carries the wireless parameter configuration information of the surrounding authorized spectrum small cell and the macro base station where the terminal type base station is located, and the terminal type base station The location information, the cell configuration request message is used to indicate that the network side device allocates cell configuration information for the terminalized small cell of the terminal type base station, and the cell configuration information may be one of a physical cell identifier, a maximum transmit power, a frequency point, and a tracking area code. Or a variety. Preferably, the terminal type base station sends the cell configuration request message to the network side device to transmit the data connection above the IP layer, so as to avoid occupying the RRC signaling or NAS signaling of the communication system, and improving the scalability of the control. In this case, a secure control plane connection needs to be established and maintained between the terminal type base station and the network side device.

S204. The network side device receives a cell configuration request message.

Specifically, the network side device receives the cell configuration request message, and after parsing the cell configuration request message, obtains the wireless parameter configuration information of the surrounding authorized spectrum small cell and the macro cell where the terminal type base station is located, and the location information of the terminal type base station. .

The cell identifier, if the same mobile terminal may not be able to read the PSS and the SSS, and thus cannot synchronize with the cell; the non-obfuscated allocation rule indicates that two adjacent authorized spectrum small cells of the same authorized spectrum small cell cannot allocate the same physical layer cell identifier, for example, The value range of the dedicated physical layer cell identification interval of the terminalized small cell is: X1 to X2, and the two adjacent authorized spectrum small cells of the terminalized small cell C are A and B, and the licensed spectrum small cells A and B cannot be allocated. The same physical layer cell identifier, the terminalized small cell C and the licensed spectrum small cell A cannot be assigned the same physical layer cell identity, and the terminalized small cell C and the licensed spectrum small cell cannot be assigned the same physical layer cell identity, and the network side device Selecting unused physical layer cell identity allocation in the cell identification interval of the dedicated physical layer of the terminalized small cell Small cell of the terminal C.

Further, the network side device may also allocate a physical layer cell identifier to the terminalized small cell of the terminal type base station based on the allocation rule of the space division multiplexing, specifically, the small cell allocation of the two co-frequency points whose distance is greater than the preset value. The same physical layer cell identifier, two adjacent small cells at different frequency points are assigned the same physical layer cell identifier, and when the number of physical layer cell identifiers is tight, the utilization of the physical layer cell identifier is improved, wherein the air separation is performed. The small cells described in the allocation rule are small cells of the authorized spectrum, and the small cells of the authorized spectrum may be ordinary small cells or terminal small cells. For example, the preset distance is 4 cell radii, the frequency of the small cell D and the small cell F are the same, and the small cell D and the small cell F all work on the licensed spectrum, and the distance between the two is 10 cell radius, which is greater than the pre- If the distance is 8 cell radii, the small cell D and the small cell F can be assigned the same physical layer cell identifier; for example, the working spectrum is licensed. The small cell F and the small cell G are adjacent, but the frequency points of the two are different, and the small cell F and the small cell G can be allocated the same physical layer cell identifier. It should be noted that the preset value may be set according to requirements, and the present invention is not limited. The physical layer cell identifier may be a physical cell identifier or other identifier for uniquely indicating the identity information of the cell, which is not limited by the present invention.
