[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and 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 invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Fig. 1 shows a flow diagram of a slice configuration method according to an embodiment of the invention.
As shown in fig. 1, a flow of a slice configuration method according to an embodiment of the present invention includes:
It should be noted that the slices described in the context of the present application are network slices, which are equivalent to a set of virtualized network functions and can provide the client with the network services required by the client. Further, when the client needs to use the network slice, the client may send a slice generation request to the NSMF through the CSMF, where the slice generation request carries a service level agreement required by the slice to be generated, and the service level agreement specifies a service required by the client and an expected service level, in other words, service content and service level of the slice to be generated required by the client are reflected.
And step 104, determining whether a target slice matched with the slice to be generated exists in the existing slice set or not based on the slice configuration information in the service level agreement.
The service level protocol carries slice configuration information of a slice to be generated, which is required by a client, wherein the slice configuration information comprises but is not limited to a plurality of items of uplink bandwidth, downlink bandwidth, time delay, the number of users, the number of sessions, a use area and a voice support state, and the function and the attribute of the slice to be generated are reflected from a plurality of dimensions.
And 106, if the existing slice set has a target slice matched with the slice to be generated, determining the slice to be generated based on the target slice, otherwise, newly building the slice to be generated.
And matching the slice configuration information in the service level agreement with the slice configuration information of each existing slice in the existing slice set, and searching whether the existing slice set has a target slice matched with the slice to be generated. If the target slice is the same as or similar to the slice to be generated, the slice to be generated does not need to be additionally newly built, and the slice to be generated only needs to be quickly obtained on the basis of the target slice. Therefore, the client can be served by the existing slices without newly building a slice for each client, occupation of network resources and labor time cost is reduced, slice acquisition efficiency is improved, and user experience of the client is facilitated to be improved.
In addition, if the existing slice set does not have the target slice matched with the slice to be generated, the slice to be generated can be directly newly built for the client so as to meet the actual requirement of the client.
Fig. 2 shows a flow diagram of a slice configuration method according to another embodiment of the invention.
As shown in fig. 2, a flow of a slice configuration method according to another embodiment of the present invention includes:
Since slice sharing involves network resource sharing, closely related to network security, client consent is required to be able to boot. And the slice sharing mark indicates that slice sharing is agreed, and if the slice generation request carries the slice sharing mark, the client agrees to share the existing slice with other clients when sending the slice generation request to the NSMF through the CSMF, so that the configuration step of slice sharing can be entered. Otherwise, when the slice generation request is detected not to carry the slice sharing identifier, the client does not agree with the slice sharing, and the process is terminated.
Since the slice configuration information reflects the functions and attributes of the slices from a plurality of dimensions, the matching degree between the slice to be generated and the existing slice can be determined by calculating the cosine similarity between the slice configuration information of the slice to be generated and the slice configuration information of the existing slice.
Specifically, the way of calculating the cosine similarity includes:
wherein i represents any slice configuration information in the service level agreement, AiA discrete value representing the ith slice configuration information in the service level agreement, n representing the serial number of any existing slice in the existing slice set, SniA discrete value representing the ith slice configuration information of the nth existing slice in the set of existing slices, k representing the total number of slice configuration information in the service level agreement, SimnRepresenting the cosine similarity of the slice to be generated and the nth existing slice in the existing slice set.
In this way, for each existing slice, in the calculation process, the difference between each item of slice configuration information of the slice to be generated and each item of slice configuration information of the existing slice needs to be considered, so that the obtained cosine similarity can reflect the overall similarity degree of the slice to be generated and the existing slice.
If the cosine similarity corresponding to an existing slice is the maximum value of the cosine similarities of all the existing slices, the existing slice is most similar to the required slice to be generated, and the existing slice can be determined as an object which can be taken by the client.
Further, the predetermined similarity threshold value represents the lowest similarity of the existing slice and the to-be-generated slice when the existing slice can replace the to-be-generated slice to serve the client, and if the maximum value is greater than or equal to the predetermined similarity threshold value, the existing slice has the possibility of replacing the to-be-generated slice to serve the client.
In this case, it is necessary to further verify whether the available network resources of the target slice can cover the required network resources of the slice to be generated.
And step 210, newly building the section to be generated.
Otherwise, if the maximum value is smaller than the predetermined similarity threshold, it indicates that the existing slice does not have the possibility of replacing the slice to be generated to serve the client, and at this time, no existing slice can be used for the client, and the slice to be generated needs to be newly created for the client.
When whether the available network resources of the target slice can cover the required network resources of the slice to be generated is further checked, if the available network resources of the target slice can cover the required network resources of the slice to be generated, the available network resources of the target slice are enough to be used by the client, and the target slice can be directly set as the slice to be generated.
If the available network resources of the target slice cannot cover the required network resources of the slice to be generated, it is indicated that the available network resources of the target slice are not enough to support the use of the client, and the capacity expansion of the available network resources of the target slice is required. Specifically, a newly-added network resource matching the shortage of the available network resource may be acquired for the target slice, and the target slice after acquiring the newly-added network resource is set as the to-be-generated slice, that is, the target slice is added to the target slice as the to-be-generated slice for the network resource lacking for the client service.
In conclusion, an applicable target slice can be matched in the existing slices for the client in a cosine similarity calculation mode, and then network resources enough for serving the client are configured for the target slice, so that network slice sharing of the client is realized.
In one possible design, when it is detected that the number of unoccupied users of the target slice is smaller than the number of required users of the slice to be generated, determining the number of difference users between the number of unoccupied users and the number of required users; sending a user permission request corresponding to the difference user number to a network element of the target slice; responding to a permission response of the network element to the user permission request, and newly adding the difference value user number for the target slice; and setting the target slice with the newly increased number of the difference users as the slice to be generated.
That is to say, when the number of users of the target slice is insufficient, the user permission is requested to the network element of the target slice to purchase the number of users, so as to complete the capacity expansion of the target slice, and the requirement of the client can be effectively supported.
In one possible design, an enterprise client sends a slice generation request to the NSMF through the CSMF, the slice generation request carries the SLA of a slice to be generated, the SLA of the slice to be generated includes but is not limited to a plurality of indexes such as uplink and downlink bandwidth, time delay, the number of users, the number of sessions, a use area, whether voice is supported and the like, and a new parameter support network slice sharing is added to indicate that shared slices are supported.
After receiving the slice generation request, the NSMF quantizes the SLA, quantizes each item in the SLA into a numerical value, and then sequentially calculates the cosine similarity with the SLA of each slice in the existing slice list for sharing, so that the cosine similarity with the S-NSSAI-1001 slice is 0.9 of the maximum value.
The predetermined similarity threshold value of network slice sharing in the NSMF is 0.8, and after comparison, the cosine similarity of the S-NSSAI 1001 slice is the maximum value 0.9 which is greater than the predetermined similarity threshold value, so that the S-NSSAI 1001 slice is most similar to the to-be-generated slice required by the enterprise client, and the S-NSSAI 1001 slice can be selected as the target slice.
Then, the NSMF performs network resource check, and finds that the maximum number of users of the S-NSSAI-1001 slice is 1000 and 900 is occupied, and the number of users requested by the slice generation request sent by the CSMF to the NSMF is 200. Further, the NSMF determines that, except for the number of users, other resources such as bandwidth and time delay of the S-NSSAI slice 1001 meet the sharing requirements of the enterprise clients.
The NSMF may send a request for adding 100 users' licenses to a network element in the S-NSSAI 1001 slice, such as SMF, UPF, UDM, PCF, etc., through a network slice subnet management function, such as CN-NSSMF, etc., the network element returns that the request is successful, and the maximum number of users in the S-NSSAI 1001 slice is increased by 100.
To this end, the NSMF returns a response to the CSMF that the sharing slice generation is successful, and selects the S-NSSAI-1001 slice to serve the enterprise user.
In another possible design, an enterprise client sends a slice generation request to the NSMF through the CSMF, where the slice generation request carries an SLA of a slice to be generated, the SLA of the slice to be generated includes, but is not limited to, multiple indexes such as uplink and downlink bandwidth, time delay, the number of users, the number of sessions, a usage area, whether voice is supported, and a parameter of support network slice sharing is added to indicate that a shared slice is supported.
And after receiving the slice generation request, the NSMF quantizes the SLA, quantizes each item in the SLA into a numerical value, and then sequentially calculates the cosine similarity with the SLA of each slice in the shared existing slice list to obtain the maximum value of the cosine similarity as 0.5.
The NSMF is internally provided with a preset similarity threshold value of 0.8, and after comparison, if the maximum value of 0.5 is smaller than the preset similarity threshold value, the NSMF initiates a standard new slice creation process, and after the slice is successfully created, the NSMF adds the newly created slice into a shared slice list, which is named as S-NSSAI 1008.
To this end, the NSMF returns a response to the CSMF that the sharing slice generation is successful, and selects the S-NSSAI 1008 slice to serve the enterprise user.
