Detailed Description
The following description of the preferred embodiments of the present invention, with reference to the accompanying drawings, will provide a better understanding of the function and features of the invention.
An embodiment of the present invention includes an ODU calibration system, configured to adjust an ODU. As shown in fig. 1, the ODU calibration system includes a mobile terminal, where the mobile terminal includes a wireless communication module for performing a wireless communication connection with an ODU.
And the wireless communication module of the mobile terminal is in communication connection with the ODU through Bluetooth or WiFi. In this embodiment, the ODU performs communication connection with the base station using an lte scheme. The lte is a network system, a transition between 3G and 4G technologies, used in mobile communication systems. The ODU is provided with a wireless communication module adapted to the mobile terminal, and the wireless communication module is in communication connection with the LTED module. The wireless communication module is a Bluetooth module or a WiFi module.
In some embodiments, the mobile terminal includes a mobile phone and an APP running on the mobile phone, and the functions of the mobile terminal are configured through the APP inside the mobile terminal. The mobile terminal has a display device that interacts with a user. The user may interact with the APP within the mobile terminal through the display device. After the mobile terminal and the wireless communication module of the ODU are connected, the user may send an instruction to the ODU through the mobile terminal and control the operation mode of the ODU.
In the process of adjusting the ODU, the ODU needs to be controlled to enter an installation mode and a manual networking mode. In this mode, a user can control a frequency band scanned by the ODU through the mobile terminal, obtain a region list that the ODU can scan, record RSRP, SINR, RSSI, and RSRQ information of the region list, and control the ODU to select a cell with a better signal for locking according to the information.
The process of conditioning the ODU is divided into primary conditioning and secondary conditioning. And the primary adjustment is used for acquiring the maximum value of the RSRP value of the wireless signal received by the ODU. The re-tuning procedure is used to adjust the pointing direction of the ODU to a direction that maximizes the RSRP value of the wireless signal it receives. To implement this functionality, the mobile terminal is configured by the APP to: displaying RSRP, SINR, RSSI and RSRQ information of a wireless signal received by the ODU in real time in the process of regulating the ODU, and recording the maximum value of the RSRP in the process of regulating the ODU for the first time; in the process of re-adjusting the ODU, when RSRP of a wireless signal received by the ODU approaches the maximum value recorded in the primary adjustment process, sending a prompt message to a user to prompt the user that the ODU has been adjusted.
The mobile terminal sends prompt information to the user through vibration and ringing. In order to facilitate adjustment, in the process of adjusting the ODU, the mobile terminal sends sounds or vibrations with different frequencies to prompt the RSRP value of the wireless signal received by the user ODU. For example, when the mobile terminal sounds a ring tone with a lower frequency and volume for a lower RSRP value, the volume and frequency of the ring tone increase as the RSRP value becomes higher. Through the change of the ring frequency, a regulator can know the influence of the regulation direction of the ODU on the RSRP value, so that the regulator can regulate the ODU to the direction with the larger RSRP value.
In some embodiments, the frequency of the ring tone is not a linear change. When the RSRP value reaches 95% of the maximum value, the frequency of the ring tone changes exponentially. In one embodiment, the RSRP value reaches 95% of the maximum value, and the frequency of the ring tone increases by 1.059 times for every one hundredth increase, corresponding to a step increase, to provide the adjustment staff with sufficient resolution during the readjustment process.
The embodiment of the present invention further includes an ODU calibration method implemented by using the ODU calibration system, where the method includes the following steps:
(S1) communicatively connecting the mobile terminal with the ODU to be tuned; the two are connected through WiFi or Bluetooth in a wireless communication connection mode.
(S2) selecting, by a mobile terminal, a frequency band searched by an ODU, and selecting a cell to which the ODU is connected; in the process of selecting a Cell, according to information such as PLMN (public land mobile network, network that can provide land mobile communication service to the public), PCI (Physical Cell Identifier, i.e., Physical Cell Identifier, and radio signal of different cells distinguished by a terminal in LTE, RSRP, EARFCN (carrier frequency point number), and the like of each Cell searched by the ODU, a Cell with the best signal is selected for connection and locking.
(S3) the ODU is subjected to primary conditioning. In the adjustment process, the direction of the ODU is adjusted in a traversal manner within the adjustment range of the ODU, the RSRP value of the wireless signal received by the ODU is recorded by the mobile terminal, and the maximum value of the RSRP value is recorded by the mobile terminal. In the process, a regulator only needs to perform traversal regulation on the ODU, and does not need to operate the mobile terminal.
(S4) re-adjusting the ODU, wherein in the adjustment process, the direction of the ODU is adjusted in a traversal mode within the adjustment range of the ODU, and when the RSRP value of the wireless signal received by the ODU reaches the maximum value, the mobile terminal sends prompting information to a user to prompt the user that the ODU is adjusted. And the mobile terminal is not required to be operated by an adjuster in the adjusting process, and the RSRP value can be prompted to the adjuster by the mobile terminal through visual sound or vibration signals. In the process, a regulator can regulate the ODU with concentration, and the distraction of the regulator is avoided.
In the re-adjustment process, the mobile terminal sends out sound or vibration with different frequencies to prompt the user of the RSRP value of the wireless signal received by the ODU. For example, when the mobile terminal sounds a ring tone with a lower frequency and volume for a lower RSRP value, the volume and frequency of the ring tone increase as the RSRP value becomes higher.
In some embodiments, the frequency of the ring tone is not a linear change. When the RSRP value reaches 95% of the maximum value, the frequency of the ring tone changes exponentially. In one embodiment, the RSRP value reaches 95% of the maximum value, and the frequency of the ring tone increases by 1.059 times for every one hundredth increase, corresponding to a step increase, to provide the adjustment staff with sufficient resolution during the readjustment process.
In the readjustment process, when the RSRP value reaches the maximum value, the mobile terminal may send out prompt information in various ways. The prompting message is in the form of one or more of periodic ring tone, periodic vibration, voice and ring tone with specific melody.
In the processes of primary regulation and secondary regulation of the ODU, the mobile terminal acquires an RSRP value of a wireless signal received by the mobile terminal from the ODU every 400ms to 600 ms. After the re-adjustment is completed, the ODU may be restarted to enter a normal operating mode.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
