Before sending the appointed interaction information, the method also comprises the steps of classifying the collected appointed interaction information and carrying out priority ordering.

The first communication node sends the collected interaction information to a second communication node, namely a target node, and the target node is determined in a mode of at least one of the following modes:
a. when the mutual information is station-level, sending the mutual information to a communication node having an interface with the first communication node;
b. when the interactive information is station-level, according to the pre-acquired longitude and latitude information, the interactive information is sent to at least one communication node which is closest to the first communication node or in a specified distance range;
c. when the mutual information is at a cell level, sending the mutual information to a communication node which has a neighboring cell relation with a problem cell where the mutual information occurs;
d. and when the interactive information is at a cell level, sending the interactive information to at least one communication node which has the maximum number of times of interoperation with a problem cell occurring in the interactive information or specifies a threshold of the number of times of interoperation, wherein the number of times of interoperation can be switching times, load balancing times and the like.
Wherein, when the interactive information is station-level, specifically: the information belongs to the granularity of a communication node unit and cannot belong to a more subdivided next-level unit, namely the interactive information belongs to the communication node and does not belong to the next-level unit of the communication node; when the mutual information is at a cell level, the following is specifically mentioned: besides the attributes of the communication node, the interactive information may add the attributes of the next level unit of the current communication node, that is, the next level unit belonging to the communication node.

And the second communication node queries the corresponding adjustment strategy by combining the acquired interaction information with information such as a cell of the second communication node. The method specifically comprises at least one of the following steps:
a. and if the performance information transmitted by other sites indicates that the ratio of RI of a certain cell to 1 is very high, the second communication node controls the UE of the cell to take the problem cell out of consideration as the preferred handover cell. If a plurality of PCIs are reported by a Measurement Report (MR), other cells are preferentially switched.
b. If the standing-wave ratio of the RRU of a certain cell is found to be abnormal from the alarm data, other cells do not perform switching action on the MR reporting the certain cell, and trigger pilot frequency measurement and pilot frequency switching. For example, users with low latency requirements do not go to DTX enabled frequency bins.
c. If the performance information of a certain site finds that a certain carrier frequency/cell cannot have dual stream or the dual stream ratio is very low, other related sites can adjust the scheduling strategy: in a 4-Carrier coverage scenario, if some UE in other relevant sites supports Carrier Aggregation (CA) between 2 carriers, when CA is added between the sites, this Carrier frequency/cell is considered as the last addition choice.
d. If some station diagnostic information finds that some S1 link (marked as x) is broken from a plurality of S1 links, other related stations will adjust the interoperation policy, and if some UE of other stations accesses the x S1 link, the UE moves to the station without triggering handover, thereby preventing index degradation.
e. If the ratio information of the uplink subframe and the downlink subframe of a certain cell of a certain site is changed, the configured downlink subframe is few, and if other sites have users with large service download, the other sites do not consider the problem cell as a preferred switching cell of the users. If the MR reports a plurality of PCIs, other cells are preferentially switched.
When the alarm of the first communication node is removed or the dynamic information is removed or the performance information changes, the method steps in the first communication node are repeated again.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
Example one
Both the first communication node and the second communication node referred to in the following may be either source nodes or target nodes. As shown in fig. 4, a policy is added in a policy module in the communication node: numbering 01, wherein the alarm content is standing wave ratio alarm of some antennas in an Active Antenna Unit (AAU) or serious interference of a frequency band part area, and a corresponding strategy is that a user with large flow rate is switched to a pilot frequency cell covered by the same;
when a certain antenna of an AAU of a certain rack on a first communication node has standing-wave ratio alarm information or has severe interference in a frequency band part area, where the antenna standing-wave ratio alarm information is normal for a cell, but a power amplifier of one port is turned off, and for multi-antenna scale Multiple-input and Multiple-output (Massive MIMO), an information collection module on the first communication node collects current alarm information to form corresponding data: A. information is classified as "alarm"; B. the number is 01; C. the identification bit is "cell level".
And the information collection module of the first communication node inquires configuration data, obtains the identification code (Cell-ID) of the corresponding Cell from the current AAU rack, and adds the Cell-ID of the alarm related Cell at the end of the data.
And the information making module of the first communication node makes a data block with a destination address of 0.0.0.0 to bear the data.
The information issuing module of the first communication node inquires the neighboring cell configuration of the current site, obtains sites to which all neighboring cells of the cell to which the alarm information belongs, namely the problem cell belong, obtains a list of Xn ports of the sites and the site to which the current alarm cell belongs, and sends the data through the Xn port user plane of the list.
The analysis module of the second communication node receives the data of the Xn port, if the destination address is 0.0.0.0, the Next generation base station identification (gNB ID) of the first communication node corresponding to the current Xn port is recorded, and the information classification, the alarm number and the Cell-ID of the problem Cell in the received data are analyzed. And combining the configuration information according to the acquired gNB ID and Cell-ID to obtain a Cell of a second communication node adjacent to the Cell-ID of the first communication node. And sending the data received by the cell of the second communication node of the relative station and the second communication node to an execution module.
And the execution module of the second communication node receives the information, and the PCI of the problem cell can be obtained by inquiring and configuring the second communication node. If there is a large-flow user or an important user in the cell of the second communication node, when the user reports the switching measurement, if the measurement information includes a plurality of PCIs, and there is a PCI of the first communication node, switching to another cell corresponding to another PCI. If the measurement only has the PCI of the first communication node, the execution module of the second communication node inquires configuration, and when the first communication node gNB ID corresponding to the PCI is obtained, the switching request is not sent to the gNB ID of the first communication node, and the pilot frequency measurement is replaced and issued to be distributed to the user, so that the user is switched to the pilot frequency point.
If the standing-wave ratio alarm of the AAU of the first communication node is eliminated, the information collection module on the first communication node receives the current alarm to form data: A. information is classified as "alarm"; B. the number is 01; C. the identification bit is 'alarm elimination'; repeating the following steps: an information collection module on a first communication node makes user data with a destination address of 0.0.0.0; the information issuing module of the first communication node inquires the neighboring cell configuration of the current site, obtains sites to which all neighboring cells of the cell to which the alarm information belongs, namely the problem cell belong, obtains a list of Xn ports of the sites and the site to which the current alarm cell belongs, and sends the data through the Xn port user plane of the list.
And the analysis module on the first communication node receives the Xn port data and informs the execution module of the second communication node to eliminate the designated warning strategies of the designated gNB ID and the designated Cell-ID.
Example two
Both the third and fourth communication nodes mentioned hereinafter may be either source nodes or destination nodes.
If n carriers cover a scene, the UE supports carrier aggregation among m carriers (m < n), and if a certain cell (carrier frequency) cannot have dual streams and the dual stream ratio is low, the cell (carrier frequency) is considered as the carrier with the lowest priority when carrier aggregation is added.
The networking adds a strategy to a strategy module of the communication node: number 01, carrier aggregation, and the corresponding strategy is that the cell which cannot have double current and has low double current ratio is finally selected as the auxiliary carrier.
When a certain cell on the third communication node cannot perform double current, has a low double current ratio or has poor channel conditions reported by terminals in the cell in the latest period (the granularity can be in the order of minutes), the third communication node forms the collected information into data: A. information is classified as "dynamic information"; B. the number is 01; C. the identification bit is "cell level".
And the information collection module on the third communication node inquires the configuration data to obtain the Cell-ID of the corresponding Cell, adds the Cell-ID of the alarm related Cell at the end of the data, and creates user data with a destination address of 0.0.0.0.
And the information issuing module of the third communication node inquires the neighboring cell configuration of the current site to obtain sites to which all neighboring cells of the cell to which the dynamic information belongs, obtains a list of X2/Xn ports of the sites and the site to which the current alarm cell belongs, and sends data formed in the third communication node through the X2/Xn port user plane of the list.
And the analysis module of the fourth communication node receives the data of the X2/Xn port, if the destination address is 0.0.0.0, the eNB ID of the third communication node corresponding to the current X2/Xn port is recorded, and the information classification, the dynamic information number, the Cell-ID and the frequency point information of the problem Cell in the received data are analyzed.
And the analysis module of the fourth communication node combines the configuration information according to the eNB ID, the Cell-ID and the frequency point information of the third communication node to obtain a Cell of the fourth communication node adjacent to the Cell-ID of the third communication node. The analysis module of the fourth communication node sends the relevant cell of the fourth communication node of the station and the received data to the execution module.
And the execution module of the fourth communication node receives the information, and the PCI of the problem cell can be obtained by inquiring and configuring the fourth communication node. For example, m carrier aggregation is supported by a user in a cell of a fourth communication node, and a current user reports o different-frequency neighbor cell measurements (where o > m), where one measurement includes a PCI with a frequency point f and a communication node i. And when the auxiliary carrier is added, the priority ranking with the frequency point f and the cell of the PCI of the third communication node as the auxiliary carrier is lowest.
When the third communication node finds that the double current ratio of the problem cell is higher than the threshold x%, the information collection module on the third communication node collects the current information to form data: A. information is classified as "dynamic information"; B. the number is 01; C. the flag bit is "problem elimination"; repeating the following steps: the information collection module on the third communication node makes user data with a destination address of 0.0.0.0; and the information issuing module of the third communication node inquires the neighboring cell configuration of the current site to obtain sites to which all neighboring cells of the cell to which the dynamic information belongs, obtains a list of X2/Xn ports of the sites and the site to which the current alarm cell belongs, and sends data formed in the third communication node through the X2/Xn port user plane of the list.
And the analysis module of the fourth communication node receives the data of the X2/Xn port and informs the execution module of the fourth communication node to eliminate the strategy of adding priority to the specified secondary carrier of the specified eNB ID and Cell-ID.
