Description
Technical Field

Background
The network slicing technology is a key technology for providing differentiated services for different application scenes by a 5G network. Through network slicing, operators construct a plurality of special, virtual, isolated and customized logic networks on a common physical platform to meet different demands (such as time delay, bandwidth, connection number and the like) of users in different industries on network capacity. The clear SLA index is helpful for industry users to directly feel the service types and the differences provided by the network slice, and select the network slice service suitable for the business characteristics of the industry by referring to the service level defined by the SLA standard, so that the barrier of inter-industry communication is reduced. The network slice SLA, as a service agreement for providing communication services, needs to deliver service requirement information signed up by an operator with a network slice client to the operator's network. For a scene requiring newly creating a slice, the slice management system performs SLA decomposition of each domain (access network, transmission network, core network, etc.) according to the SLA requirement (such as slice list, PLMN list, maximum user number, slice service area, slice end-to-end delay, mobile level of a terminal in the slice, slice resource sharing level) of the slice by the tenant, and further performs resource allocation of each domain, including bandwidth, delay, etc

The present disclosure provides solutions [ overview of technical solutions ].
For ease of understanding, the following first explains the several terms involved in this disclosure as follows:
SLA: the generic term Service Level Agreement, service level agreement, refers to an agreement between a service provider and a user regarding the quality of service level to which a service should be delivered.
The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.
First, a network system is provided in the embodiments of the present disclosure, and the network system may be, but is not limited to, a 5G network system.
Fig. 1 shows a schematic diagram of a network system in an embodiment of the disclosure, as shown in fig. 1, where the network system includes: a first slice controller 101, a second slice controller 102, an application client 103 and an application server 104.
Wherein, the application client 103 is configured to send SLA index requirement information of each network slice to the first slice controller 101; the application server 104 is configured to send SLA index requirement information of each subnet slice in each network slice to the second slice controller 102; the first slice controller 101 is configured to issue SLA index requirement information of each network slice to a corresponding network slice; the second slice controller 102 is configured to send SLA index requirement information for each subnet slice within each network slice to the first slice controller.
Further, the first slice controller 101 is further configured to adjust SLA index requirement information of each network slice according to SLA index requirement information of each subnet slice in each network slice, and send the adjusted SLA index requirement information to a corresponding network slice; and decomposing the adjusted SLA index demand information of each network slice to obtain SLA index demand information of each sub-network slice, and issuing the SLA index demand information to the corresponding sub-network slice in each network slice.
In one embodiment of the present disclosure, the first slice controller 101 is further configured to obtain slice performance parameter information, and adjust the SLA index requirement information of each network slice according to the slice performance parameter information and the SLA index requirement information of each subnet slice in each network slice.
It should be noted that, not every network slice includes a sub-network slice, for every network slice including a sub-network slice, in implementation, the SLA index requirement information of the sub-network slices in each network slice may be sent to the first slice controller 101 by the second slice controller 102, so that the first slice controller 101 adjusts the SLA index requirement information of each network slice according to the slice performance parameter information and the SLA index requirement information of the sub-network slices in each network slice from the second slice controller 102.
It should be noted that, the first slice controller 101 in the embodiment of the disclosure refers to a network slice controller located in the first layer network; the second slice controller 102 in the embodiments of the present disclosure refers to a network slice controller located in a second tier network. Wherein the first layer network and the second layer network refer to networks of different levels in the longitudinal direction. For example, in one embodiment of the present disclosure, the first layer network may be an access network and the second layer network may be a core network.
In the case where the network system provided in the embodiments of the present disclosure is a 5G network system, the network slice in the embodiments of the present disclosure refers to a 5G network slice, that is, each functional end-to-end network slice in which the 5G network is spliced in order in the lateral direction.
In one embodiment of the present disclosure, adjusting SLA index requirement information for each network slice according to SLA index requirement information for each subnet slice within each network slice includes: the SLA index demand information of each subnet slice in each network slice is sent to the first slice controller through the second slice controller; and adjusting the SLA index demand information of each network slice according to the SLA index demand information of each subnet slice in each network slice by the first slice controller.
Those skilled in the art will appreciate that the number of slice controllers, application clients, and application servers in fig. 1 is merely illustrative, and that any number of slice controllers, application clients, and application servers may be provided as desired. The embodiments of the present disclosure are not limited in this regard. Next, an embodiment of the present disclosure provides a SLA index decomposition method, which may be applied to, but is not limited to, the network system shown in fig. 1. The method may be performed by any electronic device having computing processing capabilities.
Fig. 2 shows a flowchart of an SLA index decomposition method in an embodiment of the present disclosure, and as shown in fig. 2, the SLA index decomposition method provided in the embodiment of the present disclosure includes the following steps:
step S202, SLA index demand information of each network slice is obtained.
It should be noted that, the SLA index requirement information obtained in S202 may be, but is not limited to: availability (the percentage of time that system services can operate normally), error rate (the percentage of error requests to total requests), and system capacity (the expected load, e.g., requests per second). In fact, the obtained SLA index requirement information may be different according to the application environment or the network environment, and those skilled in the art may specifically set according to the actual situation.
The 5G network slice is divided into two dimensions, namely a longitudinal dimension and a transverse dimension, and is divided into sub-network slices according to an access network and a core network in the longitudinal direction, and then the sub-network slices form the network slices from the end to the end of each function in the transverse direction. In one embodiment of the present disclosure, the network slices in embodiments of the present disclosure may be individual functional end-to-end network slices of a 5G network that are spliced sequentially in the lateral direction.
The network slice SLA index requirement information is a part of a business agreement signed between an operator and a network slice client, and comprises the related requirements of the network slice client on services and networks provided by the operator.
Step S204, the SLA index demand information of each network slice is issued to the corresponding network slice.
It should be noted that, in S202, the SLA index requirement information of each network slice may be specified by the user, and after the SLA index requirement information of each network slice is obtained for the first time, the SLA index requirement information is issued to the corresponding network slice.
Step S206, SLA index demand information of each subnet slice in each network slice is obtained; and adjusting the SLA index demand information of each network slice according to the SLA index demand information of each subnet slice in each network slice.
Note that the above-mentioned subnet slice may include: access network slice, core network slice. The SLA index requirement information of each subnet slice acquired in S206 above may be sent by the user application. Because the SLA index requirement information of the inner-layer subnet slice can affect the SLA index requirement information of the outer-layer network slice, in the embodiment of the disclosure, after the SLA index requirement information of each subnet slice in each network slice is obtained, the SLA index requirement information of the outer-layer network slice is adjusted according to the SLA index requirement information of each subnet slice in each network slice.
In one embodiment of the present disclosure, the step S202 may receive SLA index requirement information sent by the application client to each network slice in the first layer network through a first slice controller in the first layer network; the step S206 may receive SLA index requirement information sent by the application server to each subnet slice in the second layer network through the second slice controller of the second layer network.
Further, the step S206 may be implemented as follows: the SLA index demand information of each subnet slice in each network slice is sent to the first slice controller through the second slice controller; and adjusting the SLA index demand information of each network slice according to the SLA index demand information of each subnet slice in each network slice by the first slice controller. According to the embodiment of the disclosure, the SLA index mapping and decomposition problem between the outer layer slice and the inner layer slice is realized through the linkage of the longitudinal multi-level network slice controller.
Optionally, the first layer network is an access network, and the second layer network is a core network.
And step S208, the adjusted SLA index demand information is issued to the corresponding network slice.
In the specific implementation, for the network slice which does not contain the subnet slice, the prior SLA index requirement information is reserved; and for the network slice comprising the subnet slice, adjusting the SLA index demand information of the outer layer network slice according to the SLA index demand information of the inner layer subnet slice, and then issuing the SLA index demand information to the corresponding network slice so as to update the SLA index demand information of the corresponding network slice.
Step S210, the SLA index demand information of each adjusted network slice is decomposed to obtain SLA index demand information of each sub-network slice, and the SLA index demand information is issued to the corresponding sub-network slice in each network slice.
After the SLA index demand information of a certain outer layer network slice is adjusted, the SLA index demand information of the outer layer network slice needs to be decomposed to obtain the SLA index demand information of each subnet slice in the outer layer network slice, and the SLA index demand information is issued to the corresponding subnet slice in the outer layer network slice.
In one embodiment of the present disclosure, adjusting SLA index requirement information for each network slice according to SLA index requirement information for each subnet slice within each network slice includes: acquiring slice performance parameter information; and adjusting the SLA index requirement information of each network slice according to the slice performance parameter information and the SLA index requirement information of each subnet slice in each network slice.
It should be noted that, in the embodiment of the present disclosure, the slice performance parameter information refers to parameter information for characterizing each network slice and its internal subnet slices; and according to the slice performance parameter information and the SLA index demand information of each subnet slice in each network slice, the SLA index demand information of each network slice is adjusted, so that the accuracy is higher.
Fig. 3 is a schematic diagram illustrating an implementation principle of an SLA index decomposition method in an embodiment of the present disclosure, where, as shown in fig. 3, a first slice controller refers to a slice controller of a first layer network, and is configured to obtain SLA index requirement information of each network slice in the first layer network from a client for the first time, and issue the SLA index requirement information to a corresponding network slice; the SLA index demand information of each sub-network slice in the second layer network (namely the inner layer slice of each network slice in the first layer network) is obtained from the second slice controller, the SLA index demand information of the first layer network is adjusted by combining slice performance parameter information, and the adjusted SLA index demand information is issued to the corresponding network slice; meanwhile, the SLA index demand information of the first layer network is decomposed, and the decomposed SLA index demand information is issued to the corresponding subnet slice. The second slice controller refers to a slice controller of the second layer network, and is configured to obtain SLA index requirement information of the first layer network from a client application, and transmit the SLA index requirement information to the first slice controller of the first layer network.
Fig. 4 shows a flowchart of a specific implementation of an alternative SLA index decomposition method in an embodiment of the disclosure, including the following steps:
step S402, an application client sends first SLA index requirement information to a first slice controller of a first layer network;
step S404, a first slice controller of the first layer network issues first SLA index demand information to a corresponding network slice;
step S406, the application server sends second SLA index requirement information to a second slice controller of the second layer network;
step S408, a second slice controller of the second layer network sends second SLA index requirement information to the first slice controller;
step S410, the first slice controller of the first layer network combines slice performance parameter information to adjust the outer layer SLA index requirement information, and sends the adjustment result to the corresponding network slice;
and step S412, decomposing the external SLA index demand information by the first slice controller of the first layer network, and issuing the decomposed SLA index demand information to the corresponding subnet slice.
Fig. 5 is a schematic diagram showing a comparison analysis between an SLA index decomposition method in an embodiment of the present disclosure and an SLA index decomposition method in the prior art, as shown in fig. 5, where a conventional SLA index decomposition scheme is mainly implemented by using a transverse cross-domain linkage of a controller, and based on the premise that an end-to-end network is formed by splicing network domains (access, core network, etc.) with different functions in a transverse order; when the SLA index is decomposed using the conventional scheme, sla=sla access domain+sla backbone domain+sla access domain. According to the SLA index decomposition scheme provided by the embodiment of the disclosure, the problem of mapping and decomposing the SLA index between the outer layer slice and the inner layer slice is realized through the linkage of the longitudinal multi-level network slice controller, and the problem that the traditional SLA index decomposition only focuses on the transverse cross-domain but not focuses on the longitudinal cross-layer can be solved. When the embodiment of the disclosure is used for decomposing the SLA index, sla=function (first layer SLA, second layer SLA1, second layer SLA2, second layer SLA3, slice performance parameter).
Therefore, the SLA index decomposition method provided in the implementation of the present disclosure enables SLA calculation parameters to be more and index calculation to be more accurate, and the longitudinal decomposition provided in the embodiment of the present disclosure is combined with the existing transverse decomposition, so that comprehensive and accurate automatic decomposition of SLA can be realized.

Since the principle of solving the problem of the embodiment of the device is similar to that of the embodiment of the method, the implementation of the embodiment of the device can be referred to the implementation of the embodiment of the method, and the repetition is omitted.
FIG. 6 shows a schematic diagram of an SLA index decomposition device according to an embodiment of the present disclosure, as shown in FIG. 6, the device includes: the first SLA index demand acquisition module 61, the first SLA index demand issuing module 62, the second SLA index demand acquisition module 63, the SLA index adjustment module 64, the second SLA index demand issuing module 65, and the SLA index decomposition module 66.

Alternatively, the SLA index requirement information of each network slice acquired by the first SLA index requirement acquiring module 61 may be each functional end-to-end network slice in which the 5G network is spliced in order in the lateral direction.
In one embodiment of the present disclosure, the SLA index adjustment module 64 is further configured to: acquiring slice performance parameter information; and adjusting the SLA index requirement information of each network slice according to the slice performance parameter information and the SLA index requirement information of each subnet slice in each network slice.
