Referring to fig. 1, fig. 1 is a flowchart of a method provided in the embodiment of the present application, where the method is applied to a 5G network management system.
As shown in fig. 1, the method may include the steps of:
step S101, sending a cell engineering parameter information acquisition notice to each base station; and receiving and caching the cell work parameter information acquired by the base station based on the cell work parameter information acquisition notice.
In this embodiment, the network management system may send a cell parameter information acquisition notification to each base station that establishes a link with the network management system through a southbound interface, and perform integrity protection and algorithm encryption on the notification.
Receiving messages which are sent by each link building base station and carry the cell engineering parameter information collected based on the collection notification, analyzing the message content according to the message header, storing the cell engineering parameter information in the message content into a data buffer area generated in the memory of the network management system, and identifying the cell engineering parameter information under each link building base station so as to respectively update according to the identification next time. In this embodiment, the parameter information may be cellid, gnbid, PLMN, PCI, longitude, latitude, antenna direction angle, and the like of the cell.
In another embodiment, the sending the cell parameter information collection notification to each base station includes:
when the network management system enables the work parameter information acquisition, a cell work parameter information acquisition notice is sent to each base station; alternatively, the first and second electrodes may be,
and setting the work parameter information acquisition time for the work parameter information, and sending a cell work parameter information acquisition notice to each base station by the network management system when detecting that the work parameter information acquisition time is up.
In this embodiment, the network management system may enable the acquisition of the business parameter information by setting a business parameter information acquisition switch on the network management system, and when the administrator turns on the switch, sending a cell business parameter information acquisition notification to each base station. Or in this embodiment, a business parameter information acquisition timer may be started when the business parameter information acquisition switch is turned on, a business parameter information acquisition time is set, and when the network management system detects that the business parameter information acquisition time is up, a cell business parameter information acquisition notification is sent to each base station.
Furthermore, when the working parameter information acquisition time set by the timer is up, the working parameter information acquisition time can be updated, and when the updated working parameter information acquisition time is up, a cell working parameter information acquisition notice is sent to each base station again, so that the cell working parameter information can be automatically acquired to the link establishment base station at regular time.
Optionally, the method for implementing ANR updating by using an automatic neighbor cell may further include:
sending work parameter information synchronization notice to other network management systems; and receiving and caching the work parameter information synchronously notified by the other network management systems based on the work parameter information of the network management systems.
In this embodiment, the network management system may send the cell parameter information synchronization notification to other network management systems that establish a link with the network management system through the parameter information sharing interface, so that the other network management systems send the cell parameter information stored in the memory data cache region to the network management system.
After the network management system acquires the cell working parameter information sent by other network management systems, the cell working parameter information sent by other cells is stored in a memory data buffer area of the network management system, and the cell working parameter information in the memory buffer area can be sequentially presented in a working parameter information table of a network management operation interface in a table form according to the same gnbid through a JDBC interface so as to be convenient for an administrator to maintain.
In another embodiment, the sending the work parameter information synchronization notification to other network management systems includes:

Or in this embodiment, a work parameter information synchronization timer may be started when the work parameter information synchronization switch is turned on, a work parameter information synchronization time is set, and when the network management system detects that the work parameter information synchronization time arrives, a work parameter information synchronization notification is sent to other network management systems.
Further, when the synchronization time of the working parameter information set by the timer is reached, the synchronization time of the working parameter information can be updated, and when the synchronization time of the updated working parameter information is reached, the synchronization notice of the working parameter information is sent to other network management systems again, so that the automatic timing synchronization of the working parameter information of the cell to other network management systems in the chain establishment is realized.
Step S102, receiving an unknown physical cell identity PCI sent by the base station from a terminal, inquiring a target PCI matched with the unknown PCI in cached cell parameter information, determining a cell corresponding to the target PCI as a candidate cell, and sending a neighbor cell candidate set containing cell information of the candidate cell to the base station so that the base station selects the target cell from the neighbor cell candidate set as a temporary neighbor cell.
In this embodiment, the method for acquiring the unknown PCI is not related to the present solution, and is not described herein again. The network management system receives an unknown PCI sent by a base station, inquires a target PCI matched with the unknown PCI from all cell parameter information of a memory data buffer area, determines a cell corresponding to the target PCI as a candidate cell, for example, after a terminal detects that the PCI of the target cell is 32, the terminal reports the cell to the base station through a measurement report, and the base station obtains the measurement report and analyzes the PCI of the target cell through related code streams. The network management system starts to find out all cells with PCI of 32 as a neighbor cell candidate set from the working parameter information of the memory data buffer: cell 1 (30 north latitude, 30 east longitude, direction angle α, PCI32), cell 2 (40 north latitude, 40 east longitude, direction angle β, PCI32), and cell 3 (10 north latitude, 10 east longitude, direction angle γ, PCI 32). And sending the neighbor cell candidate set to the base station through a southbound interface. In this embodiment, there are many methods for the base station to select the target cell from the candidate set of neighboring cells as the temporary neighboring cell, for example, the cell with the closest longitude and latitude, and the description thereof is omitted here.
The flow shown in fig. 1 is thus completed.
In this embodiment, the network management system automatically acquires the worker parameter information of the link establishment cell, and automatically updates the neighbor cell according to the acquired worker parameter information, thereby solving the problem that the existing method for updating the neighbor cell needs to add a large amount of worker parameter information.
In another embodiment, the present application further provides an automatic neighbor relation ANR updating method, which is applied to a base station.
As shown in fig. 2, the method may include the steps of:
step S201, receiving a work parameter information acquisition notice sent by a network management system, and sending the cell work parameter information acquired based on the work parameter information acquisition notice to the network management system.
In this embodiment, after receiving the encrypted working parameter information acquisition notification sent by the network management system, the base station performs integrity check and decryption on the notification, and generates a message conforming to the base station format according to a message header obtained by decryption.
And packaging all cell related information stored in a table structure storage module into corresponding messages, performing integrity protection and encryption on the packaged messages, converting the packaged messages into messages conforming to the format of network management messages, and sending the messages to the network management system through a northbound interface of the base station.
In another embodiment, the sending the cell parameter information collected based on the parameter information collection notification to the network management system includes:
the base station compares the information in the table structure storage module with the currently maintained cell parameter information, wherein the information in the table structure storage module comprises the cell parameter information sent to the network management system in the previous time;
if the comparison result is inconsistent, the base station updates the information in the table structure storage module to the currently maintained cell parameter information and sends an ACK message to the network management system; the ACK message carries an updated table structure storage module;
and if the comparison result is consistent, the base station sends the NACK message to the network management system.
In this embodiment, the base station compares the information in the table structure storage module with the currently maintained cell information, and if the comparison result is inconsistent due to an update, such as cellid change of a cell, PCI change, and the like, the base station replaces the cell information in the table structure storage module with the currently maintained cell information, and sends a message carrying an ACK message carrying the updated table structure storage module to the network management system. If the comparison result is consistent due to no updating, the base station directly sends NACK information to the network manager.
And after the network management system receives the message fed back by the base station and analyzes the content of the message, if the message carries an ACK message, the network management system updates according to the currently maintained cell information carried in the ACK message. Furthermore, the work attendance table on the network management operation interface can be updated, so that the administrator can maintain the work attendance table manually.
If the message carries NACK message, the network management system does not process any.
It should be noted that, if the cell working parameter information acquired based on the working parameter information acquisition notification is sent to the network management system for the first time, because the table structure storage module stores the cell working parameter information sent to the network management system for the previous time, the table structure storage module is empty at this time, the base station compares the information in the table structure storage module with the currently maintained cell information, and determines that the comparison result is inconsistent, and sends a message carrying an ACK message to the network management system.
Step S202, receiving the unknown PCI reported by the terminal, and sending the unknown PCI to the network management system, so that the network management system queries the candidate cell with the same PCI as the unknown PCI.
In this embodiment, the step of the network management system querying the candidate cell having the same PCI as the unknown PCI may refer to step S102, which is not described herein again.
Step S203, receiving the neighboring cell candidate set including the cell information of the candidate cell sent by the network management system, and selecting a target cell from the neighboring cell candidate set as a temporary neighboring cell.
In this embodiment, the step of selecting the target cell from the neighboring cell candidate set as the temporary neighboring cell may refer to step S102, which is not described herein again.
Optionally, the selecting a target cell from the neighboring cell candidate set as a temporary neighboring cell includes:
and calculating a cell closest to the cell accessed by the terminal according to the cell information, and determining the cell closest to the cell as a target cell, wherein the cell information comprises the longitude and latitude and the direction angle of the cell.
In this embodiment, the base station compares the longitude and latitude and the direction angle of the current cell with all candidate cells in the neighboring cell candidate set, calculates the cell with the closest distance by the shortest distance algorithm, and then determines the cell with the closest distance as a temporary neighboring cell.
Optionally, after selecting the target cell from the neighboring cell candidate set as the temporary neighboring cell, the method further includes:
and counting the switching success rate and the switching success frequency of the terminal for switching from the cell accessed by the terminal to the temporary neighbor cell in a period, and determining the temporary neighbor cell as a formal neighbor cell and informing the network management system when the switching success rate and the switching success frequency simultaneously meet the threshold.
In this embodiment, a neighboring KPI optimization cycle may be configured on the base station side, and a threshold for switching to a formal neighboring may be set. When the KPI optimization period of the adjacent cells is overtime, the base station counts the switching success rate and the switching success frequency of all the current temporary adjacent cells, determines the temporary adjacent cells of which the switching success rate and the switching success frequency simultaneously meet the threshold value as formal adjacent cells, and informs the network management system to update the formal adjacent cell information.
In another embodiment, after the KPI optimization cycle of the neighbor cells is overtime, the base station may also count the handover success rates of all current formal neighbor cells and temporary neighbor cells, and screen out temporary neighbor cells that satisfy the handover success rate threshold. And sequencing the successful switching times of the screened temporary adjacent cells and the formal adjacent cells from large to small, and converting the temporary adjacent cells arranged before the maximum specification number of the adjacent cells into the formal adjacent cells by the base station, wherein the maximum specification number is determined by the performance of the base station. And deleting the formal adjacent cells and the temporary adjacent cells which are arranged behind the maximum specification number of the adjacent cells.
Thus, the flow shown in fig. 2 is completed.
In this embodiment, the base station sends the working parameter information of the cell to the link-building network management system through the working parameter information acquisition event, so that the network management system realizes automatic updating of the neighboring cell, and the problem that the existing method for updating the neighboring cell needs to add a large amount of working parameter information manually is solved.
