In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example 1:
the present embodiment provides a network adjusting method, which is applied to a 5G base station, as shown in fig. 1, the method includes:
step S102: an access request of a first terminal is obtained.
In this embodiment, the first terminal may be a smartphone, a tablet computer, an unmanned aerial vehicle, an unmanned vehicle, or the like supporting a 5G network. The access request may include a terminal identifier, a slice identifier of a current request, a service identifier and quality of service (quality of service), etc. The terminal identifier may be an international Mobile Subscriber identity imsi (international Mobile Subscriber identity), the QoS means that a network can provide better service capability for specified network communication by using various basic technologies, and key indexes of the QoS mainly include: availability, throughput, delay variation (including jitter and drift), loss and the like are service quality parameter values agreed by both parties when a user signs up with an operator.
Optionally, before acquiring the access request of the first terminal, the method may further include:
dividing the 5G network into usable slices and temporary slices;
the available slices are slices with different network function configurations set according to business requirements, and the temporary slices are reserved slices without network function configurations.
In this embodiment, the available slices are slices with different network function configurations, which can meet different service requirements and correspond to different service types. It can be understood that it is difficult to implement a refined network slice design according to the service requirements of different users in the early stage of 5G network construction. Therefore, in this embodiment, an available slice corresponding to one slice identifier may correspond to a plurality of different service types, for example, may correspond to a high-speed service or a low-speed service, that is, the available slice may be a combined slice corresponding to different service types.
In this embodiment, the temporary slice is a slice that is reserved in advance and is not configured with a network function, that is, a slice that does not define a network function in advance, and may be temporarily deployed and used according to a use situation of an actual network.
Step S104: and judging whether the 5G base station is overloaded or not according to the access request and the service condition of the current available slice.
Optionally, the determining whether the 5G base station is overloaded according to the access request and the usage of the currently available slice may include:
obtaining the utilization rate of the current available slice corresponding to the slice identifier;
and judging whether the utilization rate of the current available slice is greater than or equal to a preset threshold value, if so, judging that the 5G base station is overloaded.
It should be noted that, in the 5G Network, each Slice has a unique S-NSSAI (Single Network Slice Selection Assistance Information) Slice identifier, and the gsb side and the AMF (Access and Mobility Management Function) entity side maintain a NSSAI (Network Slice Selection Assistance Information) Slice list.
In this embodiment, the 5G base station may preset different thresholds for the available slices corresponding to different slice identifiers, and when the threshold is reached, it indicates that the available slice corresponding to the slice identifier is overloaded, that is, it may be determined that the 5G base station is overloaded, and a load balancing adjustment mechanism needs to be triggered. For example, the threshold may be 90%, and when the usage rate of the currently available slice corresponding to the slice identifier reaches 90%, the 5G base station triggers the load balancing adjustment mechanism in order not to affect the internet access rate and stability of other terminals in the station.
Step S106: if so, starting the temporary slice to serve the first terminal, and switching a second terminal meeting preset adjustment conditions in the 5G base station to the 4G network so as to release available slice resources of the corresponding 5G network.
In this embodiment, the load balancing adjustment mechanism triggered by the 5G base station may include: and starting the temporary slice to provide service for the first terminal, and switching a second terminal meeting preset adjustment conditions in the 5G base station to the 4G network. The second terminal meeting the preset adjustment condition may be a terminal where the current service can access the 4G network, or a terminal that resides in the 5G network but does not perform any operation, and when the available slice resources of the 5G network are insufficient, the second terminal is switched to the 4G network, thereby dynamically adjusting the network load and reducing the load of the 5G base station.
Optionally, switching a second terminal meeting a preset adjustment condition in the 5G base station to the 4G network may include:
acquiring access information of at least one second terminal of a current available slice corresponding to an access slice identifier in a 5G base station, wherein the access information comprises the terminal identifier, a service identifier and quality of service (QoS);
selecting a terminal with a service corresponding to the service identifier as a low-speed service from at least one second terminal as the second terminal meeting the preset adjustment condition;
determining a 4G base station meeting the switching condition according to the current position information of the second terminal meeting the preset adjusting condition;
and sending a terminal switching request to the 4G base station, wherein the terminal switching request comprises a terminal identifier and QoS (quality of service) of a second terminal meeting preset adjustment conditions, so that the 4G base station reserves resources for the second terminal meeting the preset adjustment conditions corresponding to the terminal identifier after receiving the terminal switching request, and sends a terminal switching instruction to the second terminal meeting the preset adjustment conditions corresponding to the terminal identifier, so that the second terminal meeting the preset adjustment conditions is switched to the 4G network.
In this embodiment, the 5G base station and the 4G base station may be two different physical devices of an operator, or may be two logical devices on the same physical device, that is, the 5G base station and the 4G base station may be physically co-located.
In this embodiment, the 5G base station may define a low-speed service and a high-speed service in advance according to the service type and the actual network condition, and may determine whether the service is a low-speed service according to the service identifier, where the low-speed service may operate in a 4G network. For example, the low-speed service may be a web browsing service, a voice service, a short message service, and the like, and the high-speed service may be a video service, a game service, a live broadcast service, and the like. For example, 4K high definition video has high bandwidth requirements, and VR has high requirements for both bandwidth and latency, and therefore, can be defined as high speed traffic.
In this embodiment, when a load balancing adjustment mechanism is triggered, service identifier extraction and QoS extraction corresponding to services need to be performed on services of one or more terminals next to a current 5G base station, a terminal occupying a low-speed service of an available slice is extracted, preferably, all terminals satisfying the low-speed service are obtained, required network resources are respectively calculated according to QoS, a corresponding 4G base station identifier is obtained according to current position information of a second terminal, and a terminal switching request is sent to the 4G base station, where the request includes the terminal identifier and the QoS, so as to instruct the 4G base station to reserve the corresponding network resources for the user. When the switching condition is met, the second terminals meeting the preset adjustment condition in the 5G base stations are switched to the respectively suitable 4G base stations, so that the load of the 5G base stations is reduced, and the current service of the second terminals switched to the 4G network is ensured not to be interrupted.
Optionally, if the usage rate of the currently available slice is less than the preset threshold, the method may further include:
and accessing the first terminal into the current available slice corresponding to the slice identification.
In this embodiment, if the usage rate of the current available slice is smaller than the preset threshold, it indicates that the load of the current 5G base station is light, and the first terminal may be accessed to the current available slice corresponding to the slice identifier.
Optionally, after the second terminal meeting the preset adjustment condition in the 5G base station is switched to the 4G network, the method may further include:
releasing the temporary slice resources allocated to the first terminal;
and reallocating the available slice resources released by the second terminal meeting the preset adjustment condition to the first terminal.
In this embodiment, after the load balancing adjustment is completed, the temporary slice resource allocated to the first terminal may be released, and meanwhile, the available slice resource released by the second terminal that meets the preset adjustment condition may be reallocated to the first terminal. If a plurality of second terminals switched to the 4G network are provided, it can be further ensured that other terminals with service requirements can be accessed normally.
In a specific embodiment, when a first terminal accesses a 5G base station, because the current load of the 5G base station is heavier, the first slice occupation required by the first terminal has reached a preset threshold, at this time, the 5G base station triggers a load balancing adjustment mechanism, enables a temporary slice to provide service for the first terminal, simultaneously, the 5G base station obtains the terminal identifications and QoS thereof of second terminals of low-speed services corresponding to all first slices in the current station, calculates required 4G network resources, finds a corresponding 4G base station according to the position information of at least one second terminal, sends a terminal switching request to the 4G base station, and indicates the 4G base station to reserve corresponding network resources, indicates the second terminal to switch networks after receiving an agreement response, and simultaneously releases available slice resources of the corresponding 5G network, so that when the 5G network load is heavier, the network speed is slower, and automatically distributing part of terminals running low-speed services to the 4G network, so as to realize the deep fusion of the 5G network and the 4G network.

Meanwhile, the first terminal can be more stably accessed into the 5G network through the available slice resources of the 5G network released by the second terminal, and the internet access rate of other terminals in the 5G base station is further ensured. The problems that in the prior art, due to the fact that the 5G network cannot realize full coverage at the initial stage of deployment, base station load is large easily along with continuous access of a terminal, and the current network resource is difficult to adjust in real time according to diversified services, the terminal is difficult to access to the 5G network or 5G network speed experience is poor and the like are solved.
