The network slicing technology is an important basic technology of a fifth-generation mobile communication technology (5G) network, and the network slicing can provide customized network services for different industries based on shared physical infrastructure, so that mutually isolated, function and performance customized, quality-guaranteed and end-to-end logic private network services are provided for industrial customers. A service-level agreement (SLA) is a service commitment between a network slice service provider and a network slice user. The network slice service provider should provide corresponding quality of service (QoS) guarantees to the network slice users according to the SLA commitments. The SLA may include quantifiable indicators such as an average fault interval, an average repair time, an access bandwidth, jitter, an access delay/end-to-end delay, and the like.

In addition, because a large number of cross-operation management domains and cross-manufacturer realistic conditions exist in network slicing, the slice management network element needs to design a multilayer structure and a complex north-south interface to meet the SLA guarantee of the cross-domain network slicing.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the 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 network slicing technology is an important basic technology of a 5G network, and the network slicing can provide customized network services for different industries based on shared physical infrastructure, so that the industry-oriented customers are provided with mutually isolated, function and performance customized, quality-guaranteed and end-to-end logic private network services. An SLA is a service commitment between a network slicing service provider and a network slicing user. The network slicing service provider should provide corresponding QoS guarantee to the network slicing user according to the SLA commitment. The SLA may include quantifiable indicators such as average fault interval, average repair time, access bandwidth, jitter, access delay/end-to-end delay, etc. At present, the quality assurance of network slices is mainly realized through a QoS mechanism, and because the QoS parameters of the QoS mechanism of the conventional mobile network are static global parameters preset according to service priorities, the QoS parameters can not be adjusted according to user attributes and geographic differences, nor can the QoS priorities of the same service be distinguished according to different slice attributes. In addition, because a large number of network slices cross the operation management domain and the manufacturer, the slice management network element needs to design a multilayer structure and a complex north-south interface to meet the SLA guarantee of the cross-domain network slice.
The block chain is a technical system which is commonly maintained by multiple parties, stores data in a block chain structure, ensures transmission and access safety by using cryptography, and can realize consistent storage, tampering and repudiation of the data. Ledgers in a blockchain may be stored at multiple nodes and synchronized using peer-to-peer (P2P) techniques. And confirming the record written into the account book by the multiple nodes by adopting a consensus mechanism. The block-chain storage structure of the block chain can ensure that the recorded data is not falsifiable and traceable.
Firstly, the application provides a block chain-based cross-domain SLA management architecture, which is shown in FIG. 1 and comprises application service providers 111 to 11n, network slice user SLA management network elements 121 to 12n, block link points 131 to 13n, network slice management network elements 141 to 14n, network slices 151 to 15n and a block chain network. The application service provider establishes communication connection with a network slice user SLA management network element; the block chain nodes and the network slice user SLA management network elements and the network slice management network elements establish communication connection at the same time, wherein the block chain nodes, the network slice user SLA management network elements and the network slice management network elements can be arranged in a combined manner or in a separated manner; a network slice management network element may create a network slice and establish a communication connection therewith. Specifically, the application service provider is configured to provide the application service of the network slice for the user accessing the network slice, for example, the application service provider may be an internet enterprise, a campus operator, a smart city operator, and the like, which provide a specific service. And the network slice user SLA management network element is used for converting an SLA protocol generated by negotiation between the application service provider and the network slice service provider into an SLA parameter and writing the SLA parameter into a block chain account book through an intelligent contract, wherein the network slice service provider is a mobile operator providing network slices. And the block chain node is used for providing distributed account book service and intelligent contract service based on the block chain, and recording and processing SLA parameters. And the network slice management network element is used for creating a network slice and issuing a QoS parameter template according to the SLA parameters. The network slice is used for creating a dedicated logical network for an application service provider, wherein the network slice may include an end-to-end network such as an access network and a core network, and may also include a partial network. The blockchain network refers to a network formed by blockchain link points, and the blockchain network completes synchronization of blockchain records, certificate Authority (CA) management, privacy management and the like among the blockchain link points.
Secondly, in view of the above problems, an embodiment of the present application provides a method for creating a network slice based on an SLA, and with reference to fig. 2, the method specifically includes the following steps:
201. and the block chain node determines to receive the service level agreement SLA parameter and synchronizes the SLA parameter to other block chain nodes.
The SLA parameter includes an Identity (ID) of a network slice management network element and a corresponding QoS parameter.
Firstly, before determining to receive service level agreement SLA parameters, a block link point needs to perform network slice SLA subscription, and the present application provides a network slice SLA subscription method, which, referring to fig. 3, includes the following steps:
s1, an application service provider and a network slice provider negotiate to generate an SLA protocol, and the application service provider reports the SLA protocol to an SLA management network element of a network slice user.
Specifically, an application service provider puts forward an SLA requirement of a network slice according to its service requirement and characteristics, and negotiates with a network slice service provider to reach an SLA agreement of the network slice, wherein the negotiation between the application service provider and the network slice service provider may be an offline negotiation or an online negotiation.
The SLA agreement content mainly includes the service requirements and characteristics of the application service provider itself, for example, the SLA agreement content includes: the method comprises the steps of network slice coverage area, maximum concurrent user number, registered user number, time delay, maximum guaranteed bandwidth, terminal mobility grade, whether resources are shared among slices or not, average fault interval, average repair time and the like.
And S2, the SLA management network element of the network slice user converts the received SLA agreement into an SLA parameter and reports the SLA parameter to a block chain node in the management domain of the network slice user.
Firstly, SLA parameters comprise an ID of a network slice management network element and a corresponding quality of service (QoS) parameter, wherein when the SLA parameters indicate a network slice user to create a network slice by the network slice management network element in an SLA management network element management domain, the SLA parameters comprise the QoS parameters and the ID of the network slice management network element; when the SLA parameters indicate that cross-domain network slice management network elements create network slices, the SLA parameters include ID lists of all network slice management network elements and sub-QoS parameters corresponding to the IDs of each network slice management network element.
For example, the QoS parameters include: the coverage area of the network slice, the maximum number of concurrent users and the number of registered users, time delay, the maximum guaranteed bandwidth, qoS levels corresponding to different services, qoS priority of the network slice and the like.
As another example, the list of SLA parameters is as follows:
ID of network slice management network element: ID1; qoS parameters: an ID list, a maximum concurrent connection number, a maximum user registration number, a maximum bandwidth, a bandwidth providing quality assurance, a maximum Access Point (APN) bandwidth, a minimum time delay providing quality assurance, and jitter of a base station; ID of network slice management network element: ID2; qoS parameters: an ID list, a maximum concurrent connection number, a maximum user registration number, a maximum bandwidth, a bandwidth providing quality assurance, a maximum APN bandwidth, a minimum time delay providing quality assurance, and jitter of a base station; \8230; ID of network slice management network element: IDn. QoS parameters: an ID list of a base station, the maximum concurrent connection number, the maximum user registration number, the maximum bandwidth, the bandwidth providing quality assurance, the maximum APN bandwidth, the minimum time delay providing quality assurance, and jitter.
Secondly, the network slice user SLA management network element writes the SLA parameters into the block chain nodes in the management domain of the network slice user SLA management network element through an SLA parameter uplink intelligent contract.
And S3, the network slice user SLA management network element returns a successful signing message to the application service provider, and the network slice SLA signing is successful.
Secondly, the block chain nodes in the management domain of the network slice user SLA management network element synchronize SLA parameters to other block chain nodes.
And finally, if an intelligent contract is acquired through an SLA parameter event acquisition, determining to receive an SLA parameter, wherein if the creation of a cross-domain network slice is involved, the SLA parameter is synchronized to other block chain nodes by the block chain nodes in an SLA management network element management domain of a network slice user, so the SLA parameter event acquisition intelligent contract in the block chain nodes in other management domains can also acquire the SLA parameter event, and determining to receive the SLA parameter. For example, referring to the block chain-based cross-domain SLA management architecture shown in fig. 1, when a block link point 131 receives an SLA parameter written by an SLA parameter uplink intelligent contract by a network slice user SLA management network element 121, the SLA parameter is directly synchronized to the block link points 132 to 13n, and an SLA parameter event acquisition intelligent contract in the block link points 131 to 13n acquires a new SLA parameter event.
202. The block chain node sends a first message to a network slice management network element corresponding to the ID of the network slice management network element in the SLA parameter; and the network slice management network element determines that a first message sent by the block chain node is received, and creates a target network slice.
Specifically, the network slice management network element receives the first message and creates a target network slice in the management domain of the network slice management network element, where the target network slice includes the target network element.
Further, if the creation of the cross-domain network slice is involved, a newly added SLA parameter event can trigger a plurality of network slice management network elements to create the target network slice at the same time.
203. The block link point issues the QoS parameters to the corresponding network slice management network elements according to the ID of the network slice management network elements; and the network slice management network element acquires the QoS parameters sent by the block chain nodes, and writes the QoS parameters into the QoS template to obtain the QoS parameter template.
The QoS template is pre-configured, for example, the QoS template may be obtained as a default, pre-stored, or rewritten by a back-end administrator.
204. And the network slice management network element issues the QoS parameter template to a target network element in the target network slice.
Specifically, when the target network slice is an end-to-end slice, the network slice management network element issues the QoS parameter template to the core network element and the access network element included in the target network slice, and configures the target network slice using the QoS parameter template to generate the target network slice configured with the QoS parameter template.
And when the target network slice is a non-end-to-end slice, the network slice management network element issues QoS parameter template configuration to the network elements in the target network slice created by the network slice management network element, and the target network slice configured with the QoS parameter template is generated.
Optionally, when the network slice management network element creates the target network slice in step 202, that is, the QoS parameter template in step 204 is needed, or the steps 202 to 204 may be combined into one step, and when the target network slice is created, the QoS parameter template is directly sent to the response network element.
205. And determining that the target network slice configured with the QoS parameter template is successfully created.
For the method for creating a network slice based on an SLA, an embodiment of the present application provides a method for updating an SLA of a network slice, which is shown in fig. 4 and specifically includes the following steps:
401. and determining that the updated SLA parameters are received by the blockchain nodes, and synchronizing the updated SLA parameters to other blockchain nodes.
The updated SLA parameters include an ID of the network slice management network element and its corresponding updated QoS parameters.
Further, if it is determined that the updated SLA parameter is added with the ID of the new network slice management network element, the block link point executes step 402; if it is determined that the ID list of the network slice management network elements in the updated SLA parameters is not changed or the IDs of some network slice management network elements are reduced, step 403 is directly performed.
Optionally, 402, the block link node sends a second message to the network slice management network element corresponding to the ID of the network slice management network element newly added in the updated SLA parameter. And the newly-added network slice management network element determines that a second message sent by the block chain node is received, and creates a new target network slice.
403. The block link point issues the updated QoS parameters to the corresponding network slice management network elements according to the ID of the network slice management network elements; and the network slice management network element acquires the updated QoS parameters sent by the blockchain node, and writes the updated QoS parameters into the QoS template to obtain the QoS parameter template.
404. And the network slice management network element issues the QoS parameter template to a target network element in the target network slice, and determines that the SLA of the network slice is successfully updated.
In the above scheme, as the block link node determines to receive the SLA parameter, it sends the first message and the QoS parameter to the network slice management network element corresponding to the ID of the network slice management network element in the SLA parameter; the network slice management network element determines that a first message is received, creates a target network slice, writes the QoS parameter into the QoS template to obtain the QoS parameter template, and sends the QoS parameter template to a target network element in the target network slice; and determining that the target network slice configured with the QoS parameter template is successfully created. Therefore, firstly, the QoS parameters can be generated according to the conversion of the SLA protocol, the QoS parameter template can be generated according to the QoS parameters, and then the QoS parameter template is issued to the target network element in the target network slice, so that the QoS parameters can be updated in real time, the condition that the QoS parameters are preset as static global parameters in a QoS mechanism of a traditional mobile network is avoided, and the flexibility of SLA management is improved. Secondly, the SLA parameters can be synchronized to other block chain nodes, data sharing of the SLA parameters is achieved, the requirements for north and south interfaces of the network slice manager are reduced, and compatibility of different manufacturers and different operation management domains when the network slices are in cross-domain is improved. And thirdly, newly-increased SLA parameter events can be acquired in real time through an SLA parameter event acquisition intelligent contract, the newly-increased SLA parameters are converted in time, and the flexibility of SLA management is further improved.
In the embodiment of the present invention, functional modules of the device for creating a network slice based on an SLA may be divided according to the above method embodiment, for example, each functional module may be divided corresponding to each function, or two or more functions may be integrated into one processing module. The integrated module can be realized in a hardware mode, and can also be realized in a software functional module mode. It should be noted that, the division of the modules in the embodiment of the present invention is schematic, and is only one logic function division, and another division manner may be available in actual implementation.
