Fig. 2 is a flowchart of a method for determining radio parameters of a small cell according to a second embodiment of the present invention, and this embodiment is based on the foregoing embodiment, and in this embodiment, a detailed description is given to determine sub-radio parameters of each frequency point according to system information of a cell in the first embodiment. Correspondingly, the method of the embodiment specifically includes the following operations:
Optionally, obtaining the cell under each frequency point by scanning may include: acquiring scanning information from a configuration file of a small base station, wherein the scanning information comprises full-band scanning or appointed frequency point scanning; and scanning through a radio environment map REM according to the scanning information to obtain the cell under each frequency point.
Optionally, the obtaining of the system information of the cell under each frequency point may include: determining a cell with the maximum power under each effective frequency point, and taking the cell with the maximum power as an effective cell; and acquiring system information of the effective cell under each effective frequency point, wherein the system information comprises a system information block SIB.

And 203, determining the sub-wireless parameters of the effective frequency points according to the system information of each effective cell and the PTWP of each effective frequency point.
Optionally, determining the sub-radio parameters of the effective frequency points according to the system information of each effective cell and the PTWP of each effective frequency point may include: determining an operating frequency band according to SIB3 or SIB 5; determining a system bandwidth from the SIB 2; determining Public Land Mobile Network (PLMN) identification according to the SIB 1; determining reference signal power according to PTWP of the effective frequency point; and taking the working frequency band, the system bandwidth, the PLMN identification and the reference signal power as sub-wireless parameters of the effective frequency point.
In a specific implementation, two specific ways are adopted for determining the working frequency band for each effective frequency point, wherein the first way is to select a common frequency point as a frequency point in wireless parameters of an LTE small base station and calculate a corresponding working frequency band; the second way is to select the frequency point of the pilot frequency adjacent cell as the frequency point in the wireless parameters of the LTE small base station and calculate the corresponding working frequency band.
The implementation conditions for the first mode are as follows: determining that no SIB5 exists in the system information of the active cell; or determining that SIB5 exists in the system information of the effective cell, selecting one inter-frequency neighboring cell with the highest priority in SIB5, wherein a frequency band corresponding to a frequency point of the inter-frequency neighboring cell is supported by an LTE cell base station, and determining that the priority of the inter-frequency neighboring cell with the highest priority is not higher than the cell reselection priority in SIB3, and the priority of the inter-frequency neighboring cell with the highest priority is different from the cell reselection priority in SIB 3; or determining that the SIB5 exists in the system information of the effective cell, selecting one inter-frequency neighboring cell with the highest priority in the SIB5, and determining that the frequency band corresponding to the frequency point of the inter-frequency neighboring cell is supported by the LTE cell base station itself, and determining that the priority of the selected inter-frequency neighboring cell with the highest priority is not higher than the cell reselection priority in the SIB3, and meanwhile, the priority of the inter-frequency neighboring cell with the highest priority is the same as the cell reselection priority in the SIB3, but the co-frequency reselection threshold in the SIB3 is higher than the inter-frequency reselection threshold.
Wherein, the implementation conditions for the second mode are as follows: determining that SIB5 exists in system information of an effective cell, selecting a pilot frequency adjacent cell with the highest priority in SIB5, wherein a frequency band corresponding to a frequency point of the pilot frequency adjacent cell is supported by an LTE (long term evolution) small base station, and determining that the priority of the pilot frequency adjacent cell with the highest priority is higher than the cell reselection priority in SIB 3; or determining that the SIB5 does not exist in the system information of the effective cell; or determining that SIB5 exists in the system information of the effective cell, selecting one inter-frequency neighboring cell with the highest priority in SIB5, where a frequency band corresponding to a frequency point of the inter-frequency neighboring cell is supported by an LTE cell base station, and determining that the priority of the selected inter-frequency neighboring cell with the highest priority is not higher than the cell reselection priority in SIB3, and meanwhile, the priority of the inter-frequency neighboring cell with the highest priority is the same as the cell reselection priority in SIB3, but the co-frequency reselection threshold in SIB3 is not higher than the inter-frequency reselection threshold.
The system bandwidth of the LTE small base station can be directly selected according to the system bandwidth of the SIB2 aiming at each effective frequency point; the PLMN identification of the LTE small base station can be directly selected according to the PLMN identification broadcasted in the SIB 1; the reference signal power of the LTE small base station can be directly selected according to the RTWP of the effective frequency point where the effective cell is located. For example, when three effective frequency points are determined, the working frequency Band in the sub-wireless parameters of the frequency point 1 is Band38, the system bandwidth is 6GB/s, the PLMN is identified as PLMN1, and the effective reference signal power is 300W; the working frequency Band in the sub-wireless parameters of the frequency point 2 is Band38, the system bandwidth is 6GB/s, the PLMN identification is PLMN2, and the effective reference signal power is 300W; the working frequency Band in the sub-wireless parameters of the frequency point 3 is Band38, the system bandwidth is 5GB/s, the PLMN identification is PLMN1, and the effective reference signal power is 300W. Of course, the present embodiment is only described by way of example, and the specific number of effective bins is not limited, and the specific numerical value of each effective bin sub-radio parameter is not limited.
And step 204, determining the wireless parameters of the small base station according to the sub wireless parameters of each effective frequency point.
Specifically, after determining the Radio parameters of the small cell and starting the cell, an REM period may be set in the configuration file, and when it is determined that the REM timer is overtime, all online users are released or redirected, and then the Radio frequency is turned off, for example, each connection state user initiates Radio Resource Control (RRC) connection release, or the RRC connection release message carries redirection parameters, and the user is redirected to another LTE cell, and the Radio parameters of the small cell may be re-determined according to the above steps 201 to 204 to optimize the parameters, and the Radio frequency is turned on again after the parameters are re-determined and optimized, and the cell is started. The user of the duration of the REM period may be limited according to actual needs, and in this embodiment, the duration of the REM period is limited.
According to the technical scheme of the embodiment of the invention, the cells under each frequency point are obtained by scanning each frequency point, the system information of the cells under each frequency point is obtained, and the wireless parameters of the small base station are automatically determined according to the sub wireless parameters of each frequency point, so that the configuration of the wireless parameters of the small base station is automatically completed without the participation of technicians, the configuration and operation and maintenance work is simple, and a large amount of labor and time cost are saved. And different modes are selected for determining the wireless parameters according to different conditions, so that the determined wireless parameters are more accurate.
