In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Example 1:
The embodiment 1 of the invention firstly provides an electricity consumption information acquisition system which comprises a plurality of regional servers and a central server with different regional grades; the regional level is generally divided by taking administrative areas as units, and as shown in fig. 1, for example, the regional level comprises a city-level regional server, a provincial-level regional server and a central server, the provincial-level regional level is higher than the city-level regional level, the electricity consumption data acquired by the city-level regional server is transmitted to the provincial-level regional server, and the provincial-level regional server transmits the received electricity consumption data to the central server, so that layer-by-layer aggregation reporting of the electricity consumption data is realized, and finally the central server is reached. It should be noted that, in fig. 1, for example, only two provincial area servers and four municipal area servers are included, and in practical use, the provincial area servers may also include county level, town level, rural level and other area levels, and may also divide a plurality of provinces into a tile, and a tile-level area server is set up for receiving electricity data of the tile (i.e. the electricity data sent by each province in the tile is collected), and then the electricity data of the tile is sent to the central server. And before the power consumption data are sent by the servers in each region, the power consumption data can be cleaned, so that unnecessary data of the upper server can be cleaned, and the transmitted data quantity is reduced. Based on the above-mentioned electricity consumption information collection system, embodiment 1 of the present invention provides an electricity consumption information collection method based on a 5G slicing technology, where it needs to be explained that an execution body of the method is an access and mobility management function (ACCESS AND Mobility Management Function, abbreviated as AMF) node in a 5G network, as shown in fig. 2, including:
In step 201, a transmission request from a first regional server is received; the transmission request carries an electricity consumption identifier and an electricity consumption code of a first regional server; the electricity utilization code is used for identifying the corresponding regional server; the electricity consumption codes can be obtained by requesting the regional servers from a central server in advance, and each regional server has a unique electricity consumption code. When the transmission request is sent, the first regional server sends electricity data to the AMF node when the first regional server needs to send the electricity data to the upper server, and in actual use, each regional server always uploads the electricity data in a periodic mode, namely, one time point is selected to be concentrated in a period (such as one day) to upload all the electricity data in the period. In an alternative embodiment, the transmission request may be a Non-Access Stratum (NAS) message, specifically, a registration request message, where the header of the registration request message carries the electricity identifier and the electricity code.
In step 202, after identifying that the transmission request carries a power consumption identifier, searching whether a first electric network slice exists; the first electrical network slice is a network slice that has been established and is used for power data transmission to other regional servers.
In some embodiments, the first electrical network slice is further required to be a network slice capable of providing electricity data transmission services to a first regional server; in one embodiment, all existing power usage network slices are capable of providing power usage data transmission services to the first regional server, and in another embodiment, which power usage network slice is the first power usage network slice may be determined according to one or more of the regional level of the first regional server, the emergency degree of power usage data transmission, the bandwidth that the power usage network slice is capable of providing, the amount of traffic that the power usage network slice needs to transmit, and the transmission quality of the transmission channel provided by the power usage network slice.
In step 203, if there is a first electric network slice, the first regional server is mounted under a transmission queue of the first electric network slice, and after other regional servers located in front of the first regional server in the transmission queue are dequeued, a transmission acceptance response is returned to the first regional server. In an alternative embodiment, the transmission acceptance response may be a NAS message, in particular a registration response message.
The mounting is understood to mean that the first electric network slice is responsible for the transmission of the electricity data of the first regional server, and the mounting does not represent an actual action, but rather means that an association relationship between the first electric network slice and the first regional server is logically established (the association relationship represents that the first electric network slice will provide the electricity data transmission service for the first regional server), and in a specific implementation, may be directly represented by storing the relevant information of the first electric network slice in correspondence with the electricity code of the first regional server. The transmission acceptance response carries slice related information of a first electric network slice, so that the first regional server uses the first electric network slice to transmit electricity data according to the slice related information of the first electric network slice; after the electricity data transmission of the corresponding regional server is finished, the regional server dequeues from a transmission queue of the application network slice; it should be noted that, in this embodiment, all the network slices refer to network slice instances, and in a practical application scenario, slice related information of the first network slice is typically a slice instance ID of the first network slice instance, where each network slice instance has a unique slice instance ID for identifying a corresponding network slice instance.
In step 204, if there is no first electrical network slice, a new electrical network slice is established, the first regional server is mounted under a transmission queue of the new electrical network slice, and a transmission acceptance response is returned to the first regional server; and the transmission acceptance response carries slice related information of the new power utilization network slice. The implementation main body of the embodiment is an AMF node, and more specifically, is an AMF node in a local network (e.g., a core network of an area where the first regional server is located, and a network corresponding to a machine room of the area) of the first regional server, where the network slice searched by the AMF node is also only a network slice in the local network.
Because the data size of the electricity consumption data is generally larger, if one electricity consumption network slice is established to transmit the electricity consumption data of all regional servers, more network elements are needed to be contained in the electricity consumption network slice, so that larger bandwidth is provided, but the network resources are occupied in a mode, if the electricity consumption network slice is kept to exist continuously, the network resources are continuously occupied, and if the electricity consumption network slice is dynamically newly established according to transmission requirements, a large amount of resources are consumed in a newly established cancellation link.
Therefore, in this embodiment, the form of providing a small-sized power consumption network slice for each regional server is considered to be an independent form, so as to reduce network resources occupied by the power consumption network slice, improve flexibility of resource variation, and in consideration that transmission of power consumption data is not generally required to be real-time, in this embodiment, multiplexing is further performed on the power consumption network slice, that is, in a survival period of a network slice newly created due to power consumption requirement of a corresponding regional server, multiplexing is allowed to be performed on other regional servers (that is, steps 202-203 described above), that is, power consumption data is provided for other regional servers, and power consumption data transmission sequences of the regional servers mounted under one power consumption network slice are sequentially transmitted according to the sequence of transmission requests, so as to ensure resource utilization rate of the power consumption network slice to be improved, and reduce the number of newly-created cancellation times of the network slice.
In actual use, after the other regional servers located before the first regional server in the transmission queue dequeue, a transmission acceptance response is returned to the first regional server, as shown in fig. 3, which specifically includes:
in step 301, it is determined whether other area servers exist in the transmission queue, and if other area servers exist in the transmission queue, a transmission waiting response is returned to the first area server, so that the first area server waits for receiving a subsequent transmission acceptance response after receiving the transmission waiting response; and after receiving the transmission waiting response, the first regional server keeps the session with the AMF uninterrupted, so as to wait for receiving a subsequent transmission acceptance response. The transmission wait response is merely to ensure that the first regional server knows that the transmission request has been received by the AMF node. The transmission waiting response may also be a registration response message, but a preset waiting flag is carried in a message header of the registration response message, so that the first regional server can identify the message as the transmission waiting response when identifying the preset waiting flag.
In step 302, a transmission acceptance response is returned to the first zone server until the first zone server reaches the head of the transmission queue, as shown in fig. 4. And after the electricity data transmission of the corresponding regional server is finished, dequeuing the corresponding regional server from the queue head of the mounted electricity network slice, and enabling the next regional server in the transmission queue to reach the queue head.
In some embodiments, for ease of management, the management of the power usage network slices is performed using power usage slice entries; in an alternative embodiment, as shown in fig. 5, the electricity consumption slice table entry stores the slice instance ID of the electricity consumption slice, electricity consumption codes of the area servers mounted under the electricity consumption slice, area level of the area servers and other area server related information, the area level can be represented by numbers when stored, the meaning of specific numbers is analyzed by those skilled in the art, for example, 4 represents town level, 3 represents county level, 2 represents city level, 1 represents province level and the like, fig. 5 is only an example, in actual use, the electricity consumption slice table entry can exist in various forms such as xml form, text form, custom structure and the like, and the searching whether the first electricity consumption slice exists or not specifically includes:
Searching whether the electricity consumption slice table item is empty, and if the electricity consumption slice table item is not empty, selecting one electricity consumption network slice from the electricity consumption slice table item as a first electrical network slice; any one of the used network slices may be selected as the first network slice.
Or, searching whether the electricity consumption slice table item has an electricity consumption network slice with the slice level matched with the first area level; if a matched power utilization network slice exists, the power utilization network slice is used as a first power utilization network slice; wherein, the first regional level is carried by a regional server and sent to an AMF node in the transmission request; when the corresponding power utilization network slice is loaded with other regional servers, taking the regional level of the regional server loaded by the power utilization network slice as the slice level of the power utilization network slice, wherein the slice level of the power utilization network slice with the slice instance ID of 001 in FIG. 5 is 4; when no other regional server is mounted under the corresponding power utilization network slice, the slice level of the power utilization network slice is matched with any regional level, or the regional level of the historically mounted regional server is used as the slice level of the power utilization slice. The slice level matching the first region level may be: the slice level is the same as the first regional level, and considering that the data amount of the power consumption data which is usually required by regional servers in the same regional level and is transmitted to a superior server is always in the same level, the amounts of network resources required by the regional servers are relatively close, so that the transmission quality (including transmission bandwidth and the like) of the power consumption data transmission of the subsequent regional servers can be better ensured by multiplexing the power consumption network slices with the slice level matched with the first regional level, and the resources of the network slices can be more fully utilized.
In some embodiments, such as when there are a plurality of power usage network slices in the power usage slice table entry whose slice levels match the first regional level, as shown in fig. 6, the method further comprises:
in step 401, receiving historical traffic rules of each regional server and transmitted traffic of each regional server; The transmitted traffic is counted by a session management function (Session Management Function, SMF) node and sent to an AMF node, and the historical traffic law is generated by an operation server and sent to the AMF node, specifically: the SMF node performs statistics of transmitted flow for each regional server according to the electricity consumption codes carried in each service message, the transmission flow of each regional server obtained through statistics is sent to the AMF node and the operation server, and the operation server generates the historical flow law according to the historically received transmission flow of each regional server; Each network slice includes a corresponding SMF node, for statistics of transmission traffic in the network slice, as shown in fig. 7, when a service packet of a regional server is transmitted by using a corresponding power consumption network slice, the SMF node firstly passes through the SMF node, and distinguishes which regional server the service packet belongs to according to power consumption codes, so that traffic statistics is performed, the traffic counted by the SMF node is sent to an operation server, on one hand, an operator is convenient to charge according to the traffic, and on the other hand, the operation server also synthesizes total traffic consumed by the regional server for power consumption data transmission each time in a period of time, and finds a historical traffic rule. it should be noted that fig. 7 is merely a partial connection diagram presented for the purpose of rendering the relationship between the partial network elements, and a schematic diagram of an actual 5G network is shown in fig. 8, which includes: network open function (Network Exposure Function, abbreviated as NEF) node, network storage function (NF Repository Function, abbreviated as NRF) node, policy control function (Policy Control Function, abbreviated as PCF) node, unified data management function (Unified DATA MANAGEMENT, Abbreviated as: UDM), application functions (Application Function, abbreviated as: AF) node, authentication service function (Authentication Server Function, abbreviated as: AUSF) node, AMF node, SMF node, user plane function (User plane Function, abbreviated: UPF) node and User Equipment (User Equipment, abbreviated as: UE), data Network (Data Network, abbreviated as: DN) and a radio access network (Radio Access Network, Abbreviated as: RAN), wherein the radio access network comprises a Distribution Unit (DU) and a Centralized Unit (CU). the UE and AUSF nodes are communicated through an N1 interface, the AMF nodes and the CU are communicated through a CU, the CU and the UPF nodes are communicated through an N3 interface, the UPF nodes and the SMF nodes are communicated through an N4 interface, and the UPF nodes and the DN are communicated through an N6 interface.
In step 402, calculating to obtain the remaining occupation time of each power consumption network slice according to the historical flow rule of each regional server and the transmitted flow of each regional server; in some embodiments, the historical flow law may be: averaging the total flow transmitted by the corresponding regional server each time to obtain average total flow, and taking the average total flow as a historical flow rule; in other embodiments, the historical flow law may also be: according to the change of the flow, a change curve of the flow along with time is established, the curve is used as a historical flow rule, and the time is substituted into the historical flow rule to calculate and obtain the flow required to be transmitted by the server in the corresponding region at the time.
The calculation is performed to obtain the remaining occupied time of each power utilization network slice, specifically: and determining the flow required to be transmitted by each regional server according to the historical flow law of each regional server, subtracting the transmitted flow from the sum of the flow required to be transmitted by each regional server under the same applied network slice to obtain the residual flow to be transmitted of the power utilization network slice, and calculating the residual occupation time of the power utilization network slice according to the residual flow to be transmitted and the bandwidth which can be provided by the power utilization network slice.
In step 403, one of the plurality of power network slices whose slice level matches the first regional level, which has the least occupation time remaining, is taken as the first power network slice, thereby reducing the time for the first regional server to wait for data transmission.
In practical use, there is also an implementation of the step 403 described above: and finding out one of the plurality of power utilization network slices with the slice level matched with the first region level, wherein the residual occupation time of the one power utilization network slice with the minimum residual occupation time is greater than a preset time, if so, the first power utilization network slice does not exist, otherwise, the power utilization network slice is taken as the first power utilization network slice. Wherein the preset time is obtained by analysis according to requirements of a person skilled in the art.
In a preferred embodiment, a plurality of transmission priorities may be set, each transmission priority corresponds to a different preset time, the first regional server sets the transmission priority corresponding to the current power consumption data transmission according to the requirement, the transmission priority is carried into a transmission request and sent to the AMF node, the AMF node determines whether the remaining occupied time of the one power consumption network slice with the least remaining occupied time is greater than a first preset time, and if so, the power consumption network slice is taken as a first power consumption network slice; the first preset time is a preset time corresponding to the transmission priority of the current power utilization data transmission of the first regional server. When there is no first electrical network slice, the above step 204 is entered, i.e. a new electrical network slice is created. For the highest transmission priority, the selection of the first electric network slice may not be performed, but the method may directly enter the step 204 to create a new electric network slice, so as to ensure that the corresponding electric data can be transmitted quickly without waiting.
Considering that in practical use, there may be a situation that the difference between the data amounts of the electricity data is larger for the regional servers of the same regional level, for example, in general, the electricity data amount of the developed region is larger than that of the remote region, for example, the electricity data amount of the province is generally larger, so the embodiment also provides an alternative implementation manner that:
And adding an important mark to the regional server with larger electricity consumption data, wherein the important mark is carried in a transmission request and is sent to an AMF node, and when the regional server is mounted by the AMF node, the AMF node also stores whether an important mark option is carried in an electricity consumption slice list item.
If a power utilization network slice with a region server carrying an important mark exists in a plurality of power utilization network slices with slice levels matched with a first region level, the power utilization network slice is taken as a first power utilization network slice, the first region server is mounted under the first power utilization network slice, meanwhile, a new power utilization network slice is established, and the region server carrying the important mark under the first power utilization network slice is transferred and mounted under the new power utilization network slice. The operations are described in the case that the regional server carrying the important mark does not reach the head of the team, and when the regional server carrying the important mark is found to be at the head of the team, the power consumption data transmission of the regional server is explained to be started, and the regional server is regarded as not carrying the important mark.
In summary, the present embodiment also provides an alternative implementation manner, which is as follows:
When no power utilization network slice with the slice level matched with the first area level exists, or the current transmission priority of the first area server is the highest transmission priority, a new power utilization network slice is established, and the first area server is mounted under the new power utilization network slice.
If only one power utilization network slice with the slice level matched with the first area level exists and the remaining occupied time of the power utilization network slice is smaller than or equal to the first preset time, the power utilization network slice is directly used as a first power utilization network slice, and a first area server is mounted under the first power utilization network slice.
If the power utilization network slices with the slice levels matched with the first regional levels exist, and the residual occupation time of all the matched power utilization network slices is larger than the first preset time, a new power utilization network slice is established, the assumption that the regional server carrying the important mark is transferred and mounted to the new power utilization network slice is made, whether the residual occupation time of the matched power utilization network slice exists under the assumption is smaller than or equal to the first preset time is calculated, if so, the first regional server is mounted to the power utilization network slice with the minimum residual occupation time under the assumption, and the action that the regional server carrying the important mark is transferred and mounted to the new power utilization network slice is implemented; if the first regional server does not exist, the regional server carrying the important mark is kept unchanged under the original power utilization network slice, and the first regional server is directly mounted under the power utilization network slice with the minimum residual occupation time.
If a plurality of power utilization network slices with slice levels matched with the first regional level exist, and the residual occupation time of at least one matched power utilization network slice is smaller than or equal to the first preset time, the first regional server is directly mounted under the power utilization network slice with the minimum residual occupation time.
In actual use, the method further comprises:
receiving a transmission ending request from a first regional server, and dequeuing the first regional server from a transmission queue of a corresponding power utilization network slice according to the transmission ending request; the transmission ending request carries a power utilization identifier and a power utilization code of a first regional server; i.e. the first regional server is off-load.
And/or, the SMF node performs flow statistics for each regional server according to the electricity consumption codes carried in each service message, and when the statistics shows that the flow of the first regional server is less than or equal to the preset flow for a period of time exceeding a first preset period of time, the AMF node sends a mounting canceling message to the AMF node, and the AMF node dequeues the first regional server from a transmission queue of a corresponding electricity consumption network slice according to the mounting canceling message; the AMF node carries an electricity code of the first regional server; when the flow of the first regional server is smaller than or equal to the preset flow and the duration exceeds the first preset duration, the first regional server is considered to be disconnected or the transmission of electricity data is finished, so that the mounting of the first regional server is canceled, and the situation that the first regional server occupies the resources of the electricity consumption network slice for a long time is avoided.
And when the duration of the region server which is not mounted under the corresponding power utilization network slice exceeds the second preset duration, the power utilization network slice is logged off. Wherein the preset flow, the first preset duration and the second preset duration are all obtained by empirical analysis by a person skilled in the art. And when the time length of the region server which is not mounted under the corresponding power utilization network slice exceeds the second preset time length, the power utilization network slice is considered to be idle for a long time, and the power utilization network slice is logged out.
In order to further ensure the security of transmission, this embodiment also provides an alternative implementation manner, that is, the electricity consumption codes of the area servers mounted under the corresponding electricity consumption network slice are sent to the SMF nodes under the electricity consumption network slice, the SMF nodes store the electricity consumption codes, and the synchronization is maintained between the AMF nodes and each SMF node, that is, when the corresponding area servers are not mounted, the step is performed as well, so that the SMF nodes update the electricity consumption codes stored by themselves, thereby ensuring the synchronization; the transmission of electricity data by using the first electric network slice, as shown in fig. 9, specifically includes:
In step 501, the SMF node receives a service packet from a first regional server; the service message carries power consumption data, power consumption codes of the first regional server and slice related information of the first electric network slice; in an alternative embodiment, the service packet may be an internet protocol sixth edition (Internet Protocol Version, abbreviated as IPv 6) packet, which includes one or more of an IPv6 basic header, an IPv6 extension header, and an ethernet header, and the slice instance ID, the electrical identifier, and the electrical code may be carried in any one or more of the IPv6 basic header, the IPv6 extension header, and the ethernet header.
As shown in fig. 10, that is, the format of the service packet carries the slice instance ID, the electrical identifier and the electrical code in the IPv6 extension header, fig. 10 is for example in the form of a hop-by-hop alternative header of the type of the IPv6 extension header, and in fig. 10, the slice instance ID, the electrical identifier and the electrical code are all carried in one extension header, and in practical use, it is equally feasible to carry the slice instance ID, the electrical identifier and the electrical code in different extension headers respectively.
In step 502, after recognizing the power consumption code of the first regional server, the SMF node obtains that the first regional server is mounted under the power consumption network slice (that is, determines that the power consumption code of the first regional server is consistent with at least one of the power consumption codes stored in the first regional server), and sends the service message to a network element in the power consumption network slice (such as a user plane management function (User Plane Function, UPF) node in fig. 7), so that the network element in the power consumption network slice transmits the service message.
In step 503, if the SMF node determines that the power consumption code of the first regional server is not within the range of the power consumption code stored in the SMF node, the service packet is discarded, and no subsequent transmission is performed.
In this embodiment, the electrical code and the related information of the electrical network slice are used to perform two-time security authentication, wherein the first time passes through the related information of the electrical network slice to ensure that the service message and other service messages of the regional server which is not mounted under the corresponding electrical network slice cannot reach the corresponding SMF node, and the second time passes through the electrical code to ensure that the service message and other service messages of the regional server which is not mounted under the corresponding electrical network slice cannot be transmitted subsequently.
In order to further optimize the use of network resources, the present embodiment also provides a preferred implementation, as shown in fig. 11, that is, the method further includes:
In step 601, the operation server performs transmission time planning for each regional server according to the historical flow rule of each regional server, so as to obtain planned transmission time of each regional server; the planning criterion is to make the planned transmission time of the next regional server just reach after the data transmission of the last regional server is finished.
In step 602, the planned transmission time of each regional server is fed back to each regional server, so that after the regional server starts power consumption data transmission according to the planned transmission time, the number of newly built power consumption network slices and the number of logging off the power consumption network slices are reduced.
Since the number of the regional servers for transmitting the electricity data in the corresponding local network is usually fixed after a period of time passes, and the historical flow rule of each regional server is generated (i.e. the data amount of the electricity data required to be transmitted by each regional server at the corresponding time is fixed), the time required for transmitting each regional server can be calculated, and each regional server is sequentially ordered according to the time sequence, if 3 regional servers exist in one local network, the time required for transmitting the s 1、s2 and s 3,s1 data is t 1,s2, the time required for transmitting the data is t 2,s3, the time required for transmitting the data is t 3, the planned transmission time of s 1 can be t 0,s2, and the planned transmission time of t 0+t1,s3 can be t 0+t1+t2; wherein t 0 can be obtained by analysis according to requirements by a person skilled in the art, for example, the relative idle time of the network can be selected as t 0, and for example, t 0 is 2 a.m.
