The terms used herein are only for the purpose of describing the embodiments of this application and are not intended to limit this application.

[0048] Before describing the embodiments of the present application in detail, some nouns and terms involved in the embodiments of the present application are first described. The nouns and terms involved in the embodiments of the present application are subject to the following interpretations:

[0049] 5GC: 5G core network is the core of 5G mobile network. It establishes reliable and secure network connections for end users and provides access to their services. The core domain handles various basic functions in mobile networks, such as connectivity and mobility management, authentication and authorization, user data management and policy management. 5G core network functions are completely software-based and designed to be cloud-native, which means they are independent of the underlying cloud infrastructure, thus achieving higher deployment agility and flexibility.

[0052] SMF: The full name of SMF is Session Management Function. Its functions include session management, such as session establishment, modification and release, including channel maintenance between UPF and AN nodes.

[0053] UDM: The full name of UDM is Unified Data Management, which is interpreted as unified data management network element in Chinese. It can provide operators with integrated data management in various networking scenarios of 2 / 3 / 4 / 5G. It has efficient user data processing capabilities, simplifies networking, is compatible with existing services, and can expand 5G services, protecting the investment of operators and providing users with the possibility of continuous and imperceptible network switching.

[0055] UE: User Equipment in English and User Device in Chinese. User devices can be mobile phones, tablet computers, laptops or other devices.

[0056] NR: The full name of NR is New Radio. 5GNR is a global 5G standard based on OFDM's new air interface design. It is also a very important foundation for the next generation of cellular mobile technology. It is also the wireless network of 5G.

[0057] QoS: It means Quality of Service in English and Quality of Service in Chinese. It refers to the ability of a network to provide better service for designated network communications by using various basic technologies. It is a network security mechanism and a technology used to solve problems such as network delay and congestion.

[0058] In the related technology, for the current 5GC, the base station in the designated area does not have the function of dynamically modifying the Qos parameters. However, for the user terminal, it is uncertain which area the user will go to. It is often encountered that a large number of user terminals gather in a certain area (such as concerts, cultural activities, etc.), causing the network in this area to be paralyzed, which will seriously affect the user experience, especially for users who need network communication urgently. The current solution of many operators is to temporarily build base stations to relieve network pressure, but for uncertain user behavior, people often disperse before the temporary base station is built. This method cannot solve the problem of high network pressure in time, and it also seriously wastes manpower and financial resources.

[0059] In view of this, a method and device for dynamically adjusting the load of a 5G base station, an electronic device and a storage medium are provided in an embodiment of the present application. The present application sets a base station flow controller between the base station and the 5G core network, and determines the real-time load quantity of the base station according to the session mapping information sent by the base station through the base station flow controller, and then sends a bandwidth adjustment request to the 5G core network according to the real-time load quantity, so that the 5GC core network generates a bandwidth modification parameter according to the bandwidth adjustment request; after the 5GC core sends the bandwidth modification parameter to the base station, the base station modifies the real-time bandwidth information according to the bandwidth modification parameter, thereby eliminating the need to temporarily build a base station, and can adjust the number of user terminals that can access the 5G wireless network, thereby effectively improving the user experience of terminal users and reducing the operating costs of operators.

[0060] The method provided in the embodiment of the present application can be applied to Figure 2 The interaction diagram is shown. Figure 2 The interaction diagram includes but is not limited to the user terminal (UE), base station, 5G core network (5GC) and base station flow controller (NRLC). The base station is equipped with a 5G wireless network (NR). The 5G core network includes AMF, SMF, UDM, UPF and PCF. The base station flow controller is used to detect the load information of the base station and send the overload notification information to the AMF of the 5G core network.

[0061] Understandably, Figure 1 is an optional flowchart of a method for dynamically adjusting a 5G base station load provided in an embodiment of the present application. Figure 1 The method may include but is not limited to steps S110 to S130:

[0062] Step S110: Acquire first session mapping information sent by the base station;

[0063] Step S120: determining the real-time load quantity of the base station according to the first session mapping information;

[0064] Step S130: Send a bandwidth adjustment request to the 5G core network according to the real-time load quantity, so that the 5GC core network generates a bandwidth modification parameter according to the bandwidth adjustment request; the 5GC core sends the bandwidth modification parameter to the base station, so that the base station modifies the real-time bandwidth information according to the bandwidth modification parameter; wherein the real-time bandwidth information is used to characterize the uplink and downlink rates of the terminal.

[0065] In the embodiment of the present application, before obtaining the first session mapping information uploaded by the base station, the base station flow controller of this embodiment will also receive the registration request information sent by the base station including the base station identifier, the maximum load number of the base station, the IP address information and the AMF address list, and register with the AMF corresponding to the base station according to the AMF address list. After the registration of the base station flow controller is completed, the base station flow controller registered with the AMF can initiate a bandwidth adjustment request to the AMF during the session. Figure 3 As shown, several base stations initiate registration requests to the base station flow controller, and the base station flow controller registers with the AMF corresponding to the base station according to the AMF address list. After the registration is completed, the base station flow controller can initiate a bandwidth adjustment request to the AMF during the corresponding session between the terminal and the base station.

[0066] After completing the registration of the base station flow controller, such as Figure 4 As shown, if the terminal (UE) initiates the creation of a PDU session, the core network processes the session data and returns the processing result to the base station. The base station pushes the session-related mapping information, such as the terminal identifier (SUP I, PEI), base station identifier, AMF information, and the current base station load to the base station flow controller. The base station flow controller queries whether the base station is in an overloaded state. If it is in an overloaded state, it sends a bandwidth adjustment request to the core network; if the base station is in a normal state, it stores the corresponding session mapping information.

[0067] It can be understood that when determining the real-time load quantity of the base station based on the first session mapping information, the terminal identifier can be determined based on the first session mapping information, the interactive load quantity can be determined based on the terminal identifier, and the current load quantity of the base station can be obtained, and then the real-time load quantity can be determined based on the interactive load quantity and the current load quantity.

[0068] In the embodiments of the present application, Figure 5 As shown, when the real-time load quantity is greater than the maximum load threshold of the base station, it is determined that the base station is in an overload state, and the NR initiates a bandwidth adjustment request to the base station flow controller. After receiving the overload notification, the base station flow controller searches for the terminal of the current base station and forwards the bandwidth adjustment request to the AMF corresponding to the corresponding terminal of all base stations. After receiving the bandwidth adjustment request, the core network (AMF, SMF, etc.) performs Qos policy control and sends it to each related network element. When the core network completes the processing, the corresponding bandwidth modification parameters are sent to the base station (NR) so that the base station reduces the real-time bandwidth information according to the bandwidth modification parameters, so that more user terminals can perform basic communication processes.

[0069] In the embodiments of the present application, Figure 6As shown, when the base station is determined to be restored from an overload state to a normal state according to the real-time load quantity, the base station sends overload elimination information to the base station flow controller; after receiving the overload elimination information, the base station flow controller searches for all first session mapping information of the corresponding base station as the second session mapping information, and sends bandwidth recovery requests to the 5G core network one by one according to the second session mapping information, so that the 5G core network recovers the bandwidth parameters of the base station according to the bandwidth recovery request. Specifically, after the core network receives the Qos bandwidth modification request modified by the base station flow controller, it synchronizes the modified Qos parameter information to the base station, so that the terminal corresponding to the base station recovers to the original Qos parameters.

[0070] It is understandable that if Figure 7 As shown, the overall implementation process of the method provided in the embodiment of the present application includes but is not limited to the following steps:

[0071] Step 1: The base station initiates registration with NRFL, and NRFL initiates registration with the AMF contained in this base station, and returns a successful registration;

[0072] Step 2: After creating the PDU session between the terminal, base station and 5G core network, the base station pushes the session related information to NRFL. NRFL detects whether the data plane of the base station where the current session is located is overloaded. If not, it continues to monitor. If it is overloaded, it initiates a Qos bandwidth reduction modification to the core network side. After receiving the modification request initiated by NRFL, the core network processes it and reduces the uplink and downlink rates of the terminal to ensure the stable operation of the base station.

[0073] Step 3: When the NRFL in monitoring state receives the data plane overload notification initiated by the base station, it will search for all session-related data of this base station and initiate QoS bandwidth reduction requests to the core network one by one to ensure the safe use of the base station and user basic functions.

[0074] Step 4: When the overloaded base station returns to normal, it will send an overload elimination message to NRFL. After receiving the overload elimination message, NRFL will search for all session-related data of this base station and send a request to the core network to increase the QoS bandwidth or restore it to normal one by one. After the core network completes the processing, the base station and the terminal return to their original state.

[0075] In summary, after setting up the network element NRFL that can dynamically adjust the base station link bandwidth strategy, the present application can not only realize dynamic QOS bandwidth adjustment through NRFL, reduce the occurrence of network paralysis in the entire base station coverage area due to sudden crowd gathering, but also reduce the cost of additional base station equipment to cope with temporary crowd gatherings, thereby ensuring the stability of the network and reducing the manpower costs such as frequent construction and dismantling of base stations.

[0076] In addition, the method of the embodiment of the present application can also access a traffic monitoring device on the base station side to collect the base station traffic status and discard the traffic according to the base station load condition, thereby reducing the pressure on the base station data plane and improving the stability of the network.
