Description

Network environment-based power situation awareness method

Technical Field

The application relates to the technical field of communication, in particular to a power situation awareness method based on a network environment.

Background

The third generation partnership project (3rd Generation Partnership Project,3GPP) is an international standardization organization responsible for developing specifications and technologies for mobile communication networks. The 3GPP defines a service-based network architecture, defining network functions as a plurality of relatively independent service modules that can be flexibly invoked. This architecture further splits a network function into several self-contained, self-managed, reusable network functions. The architecture design mode based on the service makes the network truly face the cloud design, and has various advantages, such as being convenient for the network to upgrade rapidly, improving the network resource utilization rate, accelerating the introduction of new capability of the network, and opening to a third party under the condition of authorization. For authorization openness, such as 3GPP network capability openness refers to that the 3GPP organization opens its network capabilities (e.g. protocols, interfaces, functions) to third party developers or partners so that they use these capabilities in their own applications, which may be implemented in particular by network function openness (Network Extensions Function, NEF) network elements.

In future application scenarios, deep fusion of a network defined by 3GPP and a third party network, such as deep fusion of a 5G/6G network and a third party power service, may be required, so as to provide more capability support for the third party power service, and enable the third party power service to have better service experience. However, the present NEF network element can only open the information of the shallower layer to the third party, and the deep fusion cannot be realized, so how to realize the deep fusion between the network defined by the 3GPP and the third party network is a problem to be solved at present.

2. Deep neural network (deep neural network, DNN):

DNN is a specific implementation of machine learning. According to the general approximation theorem, the neural network can theoretically approximate any continuous function, so that the neural network has the capability of learning any mapping. DNNs can be classified into feed-forward neural networks (feed forward neural network, FNN), convolutional neural networks (convolutional neural networks, CNN) and recurrent neural networks (recurrent neural network, RNN) according to the manner in which the network is constructed.

The characteristic of the FNN network is that the neurons of adjacent layers are completely connected in pairs, which makes FNNs usually require a large amount of memory space and results in high computational complexity.

CNN is a neural network dedicated to processing data having a grid-like structure. For example, both time-series data (time-axis discrete sampling) and image data (two-dimensional discrete sampling) can be regarded as data resembling a grid structure. The CNN does not use all input information for operation at one time, but uses window interception part information with a fixed size for convolution operation, thereby greatly reducing the calculation amount of model parameters. In addition, according to the different types of information intercepted by the windows (as if people and objects in the auxiliary graph are different types of information), each window can adopt different convolution kernel operations, so that the CNN can better extract the characteristics of input data.

RNNs are a class of DNN networks that utilize feedback time series information. Its inputs include the new input value at the current time and its own output value at the previous time.

In the embodiment of the invention, the indication can comprise direct indication and indirect indication, and can also comprise explicit indication and implicit indication. In the specific implementation process, the manner of indicating the information to be indicated is various, for example, but not limited to, the information to be indicated may be directly indicated, such as the information to be indicated itself or an index of the information to be indicated.

It is also possible to indicate only a part of the information to be indicated, while other parts of the information to be indicated are known or agreed in advance. For example, the indication of the specific information may also be achieved by means of a pre-agreed (e.g., protocol-specified) arrangement sequence of the respective information, thereby reducing the indication overhead to some extent. And meanwhile, the universal part of each information can be identified and indicated uniformly, so that the indication cost caused by independently indicating the same information is reduced.

The specific indication means may be any of various existing indication means, such as, but not limited to, the above indication means, various combinations thereof, and the like. Specific details of various indications may be referred to the prior art and are not described herein.

The technical solutions in the present application will be described below with reference to the accompanying drawings.

Referring to fig. 2, an embodiment of the present application provides a communication system, which may include: NMS and AF.

NMS, network management system, is a software system for monitoring, managing and controlling a network. The method can help a network manager to monitor the running state of the network more efficiently, discover and solve the problems, and improve the reliability and the safety of the network.

The NMS belongs to a network element of a management domain in a 3GPP defined network and is capable of managing a network element of a service domain (i.e., shown in fig. 1) in a 3GPP defined network. For example, the NMS has the following functions:

1. real-time monitoring the running state of the network, including the availability, performance and safety of the equipment, can be monitored in real time by the NMS.

2. Fault diagnosis-when a network fails, the NMS can quickly locate the problem and provide a solution.

3. Configuration management-the NMS can manage the configuration of devices in the network, ensuring that the devices are operating in the correct configuration state.

4. Security management-NMS can monitor the security status of the network to prevent unauthorized access and attacks.

5. Reporting and analysis the NMS may generate reports and analyses that help network administrators to better understand the operation of the network.

In addition, the NMS may be deployed on a variety of devices such as servers, routers, switches, and the like. It may be integrated with other network management tools, such as a network monitor, security log analyzer, etc., to provide more comprehensive network management functions.

The interaction of NPN and operator networks in the above communication system will be described in detail below in connection with the method.

Referring to fig. 3, an embodiment of the present application provides a power situation awareness method based on a network environment. The method may be applicable to communication between the NMS and the AF. The method comprises the following steps:

s301, the NMS sends a communication quality of service acquisition request to N RAN devices in the network.

Wherein, the network can be a network managed by the NMS, for example, the network can be a private network (NPN) to ensure the security of network development. The communication quality of service may be a quality of service acquisition request for requesting acquisition of communication to a power device accessing each of N RAN devices, N being an integer greater than or equal to 1. For example, the NMS may broadcast/unicast the communication quality of service acquisition request to N RAN devices, where the communication quality of service acquisition request may include N RAN device respective identities and N RAN device access power device respective identities for each RAN device, where M is an integer greater than 1.

In one possible implementation, the NMS may receive a service request from an application function AF. Wherein the AF is used to manage M power devices. The service request may be for requesting to perform a load adjustment service on the M power devices, e.g., the service request may include an identification of the AF, an identification of each of the M power devices, such as a subscriber permanent identifier (SUbscription Permanent Identifier, SUPI), and a cell for indicating that the request to perform the load adjustment service. The load adjustment service is a service based on dynamic power load adjustment of the network environment. As such, the NMS may send a communication quality of service acquisition request to the N RAN devices according to the service request.

Specifically, first, the NMS may determine whether the NMS has the load adjustment service opened to the AF according to the service request. If the NMS determines that the AF identification is contained in an entity/function list of load adjustment service preset by the NMS according to the AF identification in the service request, the NMS indicates that the load adjustment service is opened to the AF; otherwise, if the NMS determines, according to the AF identifier in the service request, that the AF identifier is not included in the entity/function list of the load adjustment service, it indicates that the NMS does not open the load adjustment service to the AF.

If the NMS has the function of opening the load adjustment service to the AF, the NMS determines that M pieces of power equipment are respectively accessed to the RAN equipment, and N pieces of RAN equipment are added, and sends a communication service quality acquisition request to the N pieces of RAN equipment. For example, the NMS may send a subscription request to an access and mobility management function AMF network element in the network according to the identities of each of the M power devices indicated by the service request. Wherein the subscription request is for requesting subscription to the location of each of the M power devices (i.e., which RAN device the M power devices are each currently accessing). In this way, the NMS may receive a subscription acceptance returned by the AMF network element for the subscription request, where the subscription acceptance is used to instruct each of the M power devices to access the RAN device (e.g. carry a correspondence between an identifier of each of the M power devices and an identifier of the RAN device accessed by the power device), and total N RAN devices.

If the NMS does not open the load leveling service to the AF, the NMS may determine whether the load leveling service is currently allowed to be open to the AF by verification. For example, in the case where the NMS determines that the AF is an AF subscribed to the network (e.g., the AF's identity is in an identity list subscribed to the network with a third party), the NMS may send a capability information acquisition request to the AF. Wherein the capability information acquisition request is used to indicate authentication mechanisms supported by the NMS, such as EAP AKA and/or 5G AKA. The NMS can receive a capability information acquisition response returned by the AF for the capability information acquisition request, wherein the capability information acquisition response is used for indicating an authentication mechanism supported by the AF and both the NMS and the AF selected by the AF in authentication mechanisms supported by the NMS, such as EAP AKA or 5G AKA; the NMS uses the authentication mechanism supported by both the NMS and the AF to perform security authentication on the AF. In other words, here, the principle similar to the main authentication flow at the time of UE access can be adopted, the AF is regarded as UE subscribed to the network, the NMS is regarded as AUSF, and the mutual authentication between the AF and the NMS is performed through EAP AKA or 5G AKA. The specific implementation procedure of EAP AKA or 5G AKA may be described with reference to the 3GPP defined related description, which is not described herein. If the security verification of the AF is passed, the current permission of opening the load adjustment service to the AF is indicated; otherwise, if the security verification of the AF is not passed, the load adjustment service is not currently allowed to be opened to the AF. Therefore, in the case that the load adjustment service is allowed to be opened to the AF, the NMS determines that the M power devices access the RAN devices, and N RAN devices in total, and sends a communication service quality acquisition request to the N RAN devices, which is specifically similar to the above, and will not be described again.

And S302, the NMS receives communication service quality acquisition responses returned by the N RAN devices.

The communication quality of service acquisition response may be used to indicate a communication quality of a power device accessing each of the N RAN devices, for a total of M power devices, each communication quality, M being an integer greater than 1. For example, the RAN device may instruct a power device accessing itself to perform downlink channel measurement, thereby obtaining corresponding channel state information (CQI). As such, the communication quality of each of the M power devices may include channel state information of a channel between each of the M power devices and the RAN device to which the M power devices have access, for a total of M channel state information.

S303, the NMS adjusts the power load of at least part of the M power devices according to the communication quality of each of the M power devices.

The NMS processes the M channel state information through a preset machine learning model (for example, DNN, specifically, RNN), predicts a power device a of the M power devices, where channel fading occurs, and a is an integer greater than or equal to 1 and less than or equal to M. The NMS schedules a partial power load of at least a portion of the a power devices to the B power devices. Wherein the B power devices are at least some of the M power devices that are not scheduled for a portion of the power loads. For example, the NMS may subscribe RAN devices accessed by each of the a power devices to a current power load of each of the a power devices, and the NMS may schedule partial power loads of at least some of the a power devices to B power devices according to the current power loads of each of the a power devices and the power load priority relationship between the M power devices.

The NMS may then instruct the a power devices to schedule their own partial power loads to the B power devices in a one-to-one correspondence, according to the power load priority relationship between the M power devices. For example, a power devices include power device 1, power device 2, and power device 3 in order from high to low in terms of power load priority switch, and b power devices include power device 4, power device 5, and power device 6 in order from high to low in terms of power load priority switch. The NMS may instruct the power device 1 to schedule a part of its power load to the power device 4 through the RAN device accessed by the power device 1, through the power line between the power device 1 and the power device 4. The NMS may instruct the power device 2 to schedule a portion of its power load to the power device 5 via the power line between the power device 2 and the power device 5 via the RAN device accessed by the power device 2. The NMS may instruct the power device 3 to schedule a portion of its power load to the power device 6 via the power line between the power device 3 and the power device 6 via the RAN device accessed by the power device 3. Note that the power load of the scheduled power device does not exceed the upper limit value of the load of the scheduled power device after the power load is carried by the scheduled power device. Thus, the scheduled power load may be dynamically determined and indicated to the power device by the NMS.

If a is greater than M/2 and less than M, the NMS may select B power devices with a higher power load priority than B from the a power devices, denoted as B power devices #1, according to the power load priority relationship between the M power devices. forMpowerdevices,M-ApowerdevicesotherthanApowerdevicesaredenotedasBpowerdevices#2. The NMS may instruct B power devices #1 to schedule their own partial power loads to B power devices #2 in a one-to-one correspondence according to the power load priority relationship between the M power devices.

If A is equal to M, the NMS does not make dynamic adjustments to the electrical load.
