Storage management method and device for intelligent ammeter data

Technical Field

The present disclosure relates to the field of communications, and in particular, to a method and an apparatus for storing and managing data of an intelligent ammeter.

Background

The architecture enabling the edge application is an architecture of an application layer in the fifth generation mobile communication system (5th generation,5G) for using the deployed edge application by enabling a User Equipment (UE). Therefore, the user can access the nearby edge application to achieve the purpose of optimizing the resource access process of the user, such as reducing the network transmission delay between the user and the computing resource and improving the user experience. For example, edge application servers (edge application server, EAS) may be deployed near internet of things devices, such as smart meters, to enable low-latency collection of internet of things device data, such as smart meter monitoring data.

Typically, EAS may store the acquired data locally, but limited by the capabilities of the EAS, the amount of data stored locally is limited.

In order to achieve the above purpose, the present application adopts the following technical scheme:

in a first aspect, a method for storing and managing data of a smart meter is provided, where the method is applied to EAS, and a first PLMN and a second PLMN are deployed in an edge service area where the EAS is located, and the method includes: the EAS acquires monitoring data of the intelligent ammeter from the UE associated with the EAS; the method comprises the steps that an EAS determines first monitoring data and second monitoring data according to monitoring data of the intelligent electric meter, wherein the first monitoring data are associated with the monitoring data of the intelligent electric meter, and the second monitoring data are associated with the monitoring data of the intelligent electric meter; the EAS stores the first monitoring data in a first UDM network element within the first PLMN, and the EAS stores the second monitoring data in a second UDM network element within the second PLMN.

Based on the method of the first aspect, as the operator network, such as the first PLMN and the second PLMN, is also deployed in the edge service area where the EAS is located, the EAS may store the obtained relevant data, such as the first monitoring data and the second monitoring data, in the first UDM network element in the first PLMN and the second UDM network element in the second PLMN, respectively, that is, the data storage capability of the edge application scenario is improved by multiplexing the capability of the operator network, so as to avoid the limitation of storage caused by the capability of the EAS.

In addition, the operator network is used as granularity for distributed storage, so that the situation that all data are leaked by one operator network can be avoided, and the data storage risk is further reduced; and moreover, the data storage load of the operator network can be reduced, and excessive occupation of resources of the operator network due to data storage of the EAS is avoided.

In one possible design, the EAS determines first monitoring data and second monitoring data based on monitoring data of the smart meter, including: the EAS obtains first monitoring data through a first mapping on the monitoring data of the intelligent ammeter, and obtains second monitoring data through a second mapping on the monitoring data of the intelligent ammeter. It can be understood that the original data in the plaintext, that is, the monitoring data of the smart meter, can be prevented from being directly exposed to the network of the operator through mapping, so that the data security is improved.

Optionally, the EAS obtains the first monitoring data from the monitoring data of the smart meter through a first mapping, including: the method comprises the steps that the EAS obtains at least part of first data in monitoring data of the intelligent ammeter; the EAS maps at least part of the first data to a vector space to obtain first vector data, wherein the first vector data comprises a multi-dimensional first vector; and the EAS performs dimensionality reduction compression on the first vector data to obtain second vector data, wherein the second vector data is the first monitoring data. That is, the data amount can be reduced by the dimension reduction in the case of preserving the original data structure of the first monitoring data, so that the storage efficiency can be improved.

To facilitate understanding of the embodiments of the present application, a communication system suitable for the embodiments of the present application will be described in detail first with reference to the communication system shown in fig. 2 as an example. Fig. 2 is a schematic diagram of a communication system to which the method according to the embodiment of the present application is applicable.

As shown in fig. 2, the communication system may be applied to the above-described 5GS shown in fig. 1, and mainly includes: EAS and UDM network elements. EAS belongs to a third party service, i.e., EAS does not belong to the carrier network. EAS may use edge applications deployed in the edge service area of the carrier network, or the area where EAS is deployed may become the edge service area, i.e., the edge service area of EAS. The UDM network element may comprise a plurality of UDM network elements located within an edge service area of the EAS. The plurality of UDM network elements may each belong to a different operator network. For example, UDM network element 1 belongs to PLMN1 and UDM network element 2 belongs to PLMN2.

It will be readily appreciated that the interaction between EAS and UDM network elements will be specifically described below by way of a method embodiment in connection with fig. 3. As shown in fig. 3, the method is applied to EAS, where a first public land mobile network (public land mobile network, PLMN), i.e. a first operator network, and a second PLMN, i.e. a second operator network, are deployed in an edge service area where the EAS is located. The method comprises the following steps:

s301, the EAS acquires monitoring data of the intelligent ammeter from the EAS-related UE.

The EAS may acquire the monitoring data of the smart meter from the UE in any possible manner, such as a periodic or event triggered manner. The UE may be considered as a control terminal of the smart meters for controlling the smart meters. Optionally, the first PLMN is a home public land mobile network (home public land mobile network, HPLMN) of the UE and the second PLMN is a visited public land mobile network (visited public land mobile network, VPLMN) of the UE; alternatively, the second PLMN is an HPLMN of the UE, and the first PLMN is a VPLMN of the UE, without limitation.

S302, determining first monitoring data and second monitoring data by the EAS according to the monitoring data of the intelligent ammeter.

The first monitoring data are associated with the monitoring data of the intelligent electric meter, and the second monitoring data are associated with the monitoring data of the intelligent electric meter.

In one possible design, the EAS may obtain the first monitoring data from the monitoring data of the smart meter via a first mapping, and the EAS may obtain the second monitoring data from the monitoring data of the smart meter via a second mapping. It can be understood that the original data in the plaintext, that is, the monitoring data of the smart meter, can be prevented from being directly exposed to the network of the operator through mapping, so that the data security is improved.

For example, the EAS may acquire at least a portion of the first data in the monitoring data of the smart meter; the EAS maps at least part of the first data to a vector space to obtain first vector data, wherein the first vector data comprises a multi-dimensional first vector; and the EAS performs dimensionality reduction compression on the first vector data to obtain second vector data, wherein the second vector data is the first monitoring data. That is, the data amount can be reduced by the dimension reduction in the case of preserving the original data structure of the first monitoring data, so that the storage efficiency can be improved.

For another example, the EAS may obtain at least a portion of the second data in the monitoring data of the smart meter; the EAS maps at least part of the second data to a vector space to obtain third vector data, wherein the third vector data comprises a multidimensional third vector; and the EAS performs dimensionality reduction compression on the third vector data to obtain fourth vector data, wherein the second vector data is second monitoring data. That is, the data amount can be reduced by the dimension reduction in the case of preserving the original data structure of the first monitoring data, so that the storage efficiency can be improved.

S303, EAS stores the first monitoring data in a first UDM network element in the first PLMN, and EAS stores the second monitoring data in a second UDM network element in the second PLMN.

The EAS may encrypt the first monitoring data using a first key to obtain encrypted first monitoring data, where the first key is associated with the first PLMN or the second PLMN; the EAS stores the encrypted first monitoring data in the first UDM network element to further enhance data security. Optionally, the first key associating the first PLMN or the second PLMN means: the first key is a key deduced based on a master authentication key of the UE in the first PLMN, or the first key is a key deduced based on a master authentication key of the UE in the second PLMN, that is, the data encryption is realized by multiplexing an existing key of the operator network, so as to reduce the realization difficulty and support the current protocol. It will be appreciated that since the EAS belongs to a third party application and not to a network element within the first PLMN, the EAS has the ability to encrypt the first data using the master authentication key of the UE in the second PLMN and store it to the first PLMN.

Alternatively, the EAS may further encrypt the second monitoring data using a second key to obtain encrypted second monitoring data, where the second key is associated with the first PLMN or the second PLMN; the EAS stores the encrypted second monitoring data in the second UDM network element to further enhance data security. Optionally, the second key associating the first PLMN or the second PLMN means: the second key is a key deduced based on a master authentication key of the UE in the first PLMN, or the second key is a key deduced based on a master authentication key of the UE in the second PLMN, that is, the data encryption is implemented by multiplexing an existing key of the operator network, so as to reduce implementation difficulty and support the current protocol. It will be appreciated that since the EAS belongs to a third party application and not to a network element within the second PLMN, the EAS is also capable of encrypting the second data using the master authentication key of the UE in the first PLMN and storing it to the second PLMN.

In summary, since the operator network, such as the first PLMN and the second PLMN, is also disposed in the edge service area where the EAS is located, the EAS may store the obtained related data, such as the first monitoring data and the second monitoring data, into the first UDM network element in the first PLMN and the second UDM network element in the second PLMN, respectively, that is, the data storage capability of the edge application scenario is improved by multiplexing the capability of the operator network, so as to avoid the limitation of storage caused by the capability of the EAS. In addition, the operator network is used as granularity for distributed storage, so that the situation that all data are leaked by one operator network can be avoided, and the data storage risk is further reduced; and moreover, the data storage load of the operator network can be reduced, and excessive occupation of resources of the operator network due to data storage of the EAS is avoided.
