With the development of communication technology, the construction of 5G networks has been developed all over the country. However, in the plateau area or some remote mountain areas, the base station resources are still tight. In addition, compared with plain areas, the areas are more likely to have users gathered in the same place, which causes users to be intensively attached to several fixed base stations in plateau areas and the like, and causes overload of part of the base stations, network congestion is caused, and performance of the communication network is reduced.
In order to effectively analyze the network conditions of the plateau and the like, the network data can be analyzed by the NWDAF in the 5G network. According to the TS 3gpp 29520-g10 protocol, the NWDAF collects data by sending a data subscription message to NF (Network Function), OAM (Operation Administration and Maintenance) and AF (Application Function), and then, after the NF, OAM or AF collects corresponding data, submits the data to the NWDAF through a notification message, and then, after the NWDAF collects data each time, the data is added to the original data to be analyzed and run together, so as to obtain a data analysis report. However, the analysis and the obtained analysis report are relatively common and simple, no better optimization is performed aiming at a specific scene, and the problem of unbalanced load of a foundation station such as a plateau and the like is difficult to solve.
Based on this, the present application provides a method, a system, a device and a storage medium for balancing base station load, wherein the method for balancing base station load is applied to NWDAF in a 5G network, and the method includes: acquiring and storing base station information; sending a data subscription message to a target network element, wherein the data subscription message is used for enabling the target network element to collect user attachment information; receiving user attachment information returned by a target network element; calculating to obtain first user switching information according to the base station information and the user attachment information; and sending the first user switching information to a target network element so that the target network element performs load balancing on the base station according to the first user switching information. The NWDAF determines the first user switching information by combining the user attachment information obtained by subscription and the prestored base station information, can perform targeted optimization aiming at a specific scene such as unbalanced base station load in a plateau area, is beneficial to realizing load balance in an area with deficient base station resources, and improves the overall performance of a communication network.
The embodiments of the present application will be further explained with reference to the drawings.
Referring to fig. 1, fig. 1 is a flowchart illustrating steps of a base station load balancing method according to an embodiment of the present application, where the method is applied to NWDAF, and the method includes, but is not limited to, steps S100 to S150:
s100, acquiring and storing base station information;
specifically, base station information corresponding to all base stations in the current communication network is acquired and stored in the NWDAF, and when network data analysis is performed in subsequent steps, the NWDAF can directly call the base station information to participate in analysis.
In some embodiments, the base station information includes a base station ID, a base station location, and a base station maximum load for each base station in the network, it is understood that each base station ID corresponds to one base station location and one base station maximum load, for example, a base station with a base station ID of 1, the base station location is represented by <30,20,10>, and the base station location coordinates in turn represent the longitude, latitude, and altitude of the base station location; in addition, the maximum load of the base station is 80, which means that the maximum number of users that the base station 1 can access simultaneously is 80. For another example, the base station with base station ID 2 has base station position <30,10,10> and base station maximum load of 90. And inputting the base station information of all base stations in the network into the NWDAF.
S110, sending a data subscription message to a target network element, wherein the data subscription message is used for enabling the target network element to collect user attachment information;
specifically, according to the above content, the NWDAF may send a data subscription message to the NF, OAM, or AF, so that the NF, OAM, or AF collects user attachment information, and the user attachment information may reflect an attachment condition of a user to a base station in a current network. Therefore, the target network element in this embodiment refers to at least one of NF, OAM, or AF, and the NWDAF sends the data subscription message to one or more target network elements according to actual needs.
In the embodiment of the present application, the user attach message includes the user's attached base station ID and the user IMSI. The attached base station ID refers to a base station ID of a base station to which the user is attached. The IMSI (International Mobile Subscriber Identity) of a Subscriber is an identifier for distinguishing different subscribers in a Network, and the 15-digit IMSI is composed of 3-digit MCC (Mobile Country Code), 2-digit MNC (Mobile Network Code) and 10-digit MIN.
S120, receiving user attachment information returned by the target network element;
specifically, after the NWDAF sends a data subscription message to the target network element, the target network element collects user attachment information according to the received data subscription message, and returns the collected user attachment information to the NWDAF for subsequent data analysis by the NWDAF.
S130, calculating to obtain first user switching information according to the base station information and the user attachment information;
specifically, the NWDAF calculates, by combining the subscribed user attachment information and the pre-stored base station information, first user handover information indicating a situation that a user in the network switches the base station, for example, which users in the network need to perform base station handover, which base station to specifically switch to, and the like.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of determining handover information of a first user according to an embodiment of the present application, where the method includes, but is not limited to, steps S200 to S220:
s200, determining the real-time load of the base station according to the base station ID, the attached base station ID and the user IMSI;
specifically, according to a plurality of different IMSIs corresponding to the same attached base station ID, the number of users attached to the same base station can be determined; then, matching the attached base station ID with the base station ID can determine the number of users currently loaded by a specific base station, that is, the real-time load of each base station in the network can be determined.
S210, determining busy base stations and idle base stations with redundant network resources, wherein the busy base stations and the idle base stations are required to be reduced;
specifically, for a single base station, after determining the real-time load according to step S200, the real-time load is compared with the maximum load of the base station, so that it can be determined whether the current load has exceeded the self-supporting capability, and the number of users attached needs to be reduced.
In some embodiments, when the real-time load is greater than or equal to the maximum load of the base station, the current base station is determined as a busy base station to which the user attachment needs to be reduced, and when the real-time load is less than the maximum load of the base station, the current base station is determined as an idle base station of redundant network resources.
In practical situations, the base station is always operated at the maximum load, which further increases the network congestion and cannot make good use of resources of other base stations. Therefore, in other embodiments, when the real-time load is greater than or equal to 70% of the maximum load of the base station, the current base station is determined as a busy base station to which the user attachment needs to be reduced; on the contrary, when the real-time load is less than 70% of the maximum load of the base station, the current base station is determined to be an idle base station with redundant network resources, so that the base stations in the network are ensured to have certain idle network resources as much as possible, and the emergency situation such as a certain base station failure in the network can be better handled.
S220, determining first user switching information according to the position of the base station, wherein the first user switching information is used for switching a user attached to a busy base station to an idle base station;
specifically, first user switching information is determined according to the base station positions of different base stations in the network, and the first user switching information is used for switching users attached to busy base stations to idle base stations, so that the number of the users attached to the busy base stations is reduced, the load pressure of the busy base stations is relieved, network resources of the idle base stations are fully utilized, the load of each base station in the whole network tends to be balanced, network congestion is reduced, and the performance of the communication network is improved.
It is mentioned in the foregoing that the base station location includes the longitude, latitude and altitude of the base station. It can be understood that, in order to ensure that the user still maintains a good communication quality after switching the base station to a certain extent, the user needs to be switched from the currently busy base station to the nearby idle base station. Specifically, the NWDAF determines, according to the base station position of the base station in the network, an idle base station closest to the currently busy base station as the target base station, and the content recorded in the first user handover information is: and switching the user attached to the busy base station to the corresponding target base station.
Through the steps S200-S220, the embodiment of the application provides a scheme for determining the real-time load of the base station through the base station information and the user attachment information and determining the first user switching information according to the comparison of the real-time load and the maximum load of the base station.
Step S130 has already been described above, and step S140 will be described.
S140, updating the user attachment information according to the attached base station ID, the user IMSI and the user attachment duration;
specifically, in the embodiment of the present application, the NWDAF may periodically send a data subscription message to the target network element, that is, the NWDAF may periodically receive the user attachment information. In some embodiments, the user attachment information further includes a user attachment duration, for example, 20 minutes and 35 minutes. In the embodiment of the present application, the NWDAF needs to analyze the information of the base station in combination with the real-time load of the base station, so that the user attachment information in the NWDAF needs to be updated periodically, and a process for updating the user attachment information is described below.
First, the NWDAF determines a plurality of pieces of user attachment information of the same user attached to the same base station based on the attached base station ID and the user IMSI. And then determining the latest user attachment information from the plurality of pieces of user attachment information according to the user attachment duration, wherein the user attachment information with the longest user attachment duration is the latest user attachment information, and deleting the user attachment information except the latest user attachment information after the latest user attachment information is determined, thereby completing the process of updating the user attachment information.
S150, sending first user switching information to a target network element so that the target network element performs load balancing on the base station according to the first user switching information;
specifically, the first user switching information determined in step S130 is sent to the target network element, and after receiving the first user switching information, the target network element switches the user from the busy base station to the idle base station according to the first user switching information, thereby completing load balancing of the base stations in the network, and thus reducing network congestion in the network and improving network performance.
Through steps S100 to S150, an embodiment of the present application provides a base station load balancing method, where the method is applied to an NWDAF in a 5G network, and the method includes: acquiring and storing base station information; sending a data subscription message to a target network element, wherein the data subscription message is used for enabling the target network element to acquire user attachment information; receiving user attachment information returned by a target network element; determining the real-time load and the maximum load of each base station according to the base station information and the user attachment information, and determining whether the current base station is a busy base station or an idle base station according to the real-time load and the maximum load of the base station; and calculating to obtain first user switching information, and sending the first user switching information to a target network element so that the target network element switches users attached to busy base stations to idle base stations according to the first user switching information to complete load balancing in the network.

In some embodiments, the NWDAF may also adjust the base station load of the network during periods of relative idleness to reduce power consumption within the network. For example, setting 3 am with less traffic as an idle period, the NWDAF sends a data subscription message to the target network element in a preset idle period, the target network element returns real-time user attachment information, and a low-load base station and a high-load base station in the network are determined according to the base station information and the user attachment information returned by the target network element. The determination criteria of the low-load base station and the high-load base station may be set according to actual needs, for example, a base station with a real-time load 20% lower than the maximum load of the base station itself is considered as a low-load base station, and a base station with a real-time load 20% higher than or equal to the maximum load of the base station itself is considered as a high-load base station. And calculating to obtain second user switching information according to the low-load base station and the high-load base station in the network, wherein the second user switching information is used for switching the user attached to the low-load base station to the high-load base station. And the NWDAF sends the calculated second user switching information to the target network element, so that the target network element switches all the users on the low-load base station to the high-load base station according to the second user switching information, the low-load base station enters a standby state, the energy consumption is reduced, the high-load base station loads more users, but the energy consumption is not obviously changed, the energy consumption of the whole network is reduced, and the effect of saving energy is achieved.
