technical field

Background technique

In order to reduce the construction cost of network infrastructure, the concept of network slicing came into being. Network slicing refers to virtual end-to-end networks separated by different operators on the same network infrastructure, so that end-to-end logical isolation of traffic and network resources can be provided to provide services for different vertical industries with different service requirements.

At present, the access network equipment of operator A who undertakes the construction of a certain area network slice provides corresponding wireless resources and services according to the slice deployment strategy of operator A. When using the access network equipment of operator A, because the operators are independently operated or even compete, the users of operator B may not be able to know the slice deployment strategy of operator A, so that the access network of operator A The network equipment cannot provide corresponding slicing services for users of operator B, and correspondingly, the service capability of slicing cannot be guaranteed accordingly.

Detailed ways

In order to facilitate understanding of the technical solutions of the embodiments of the present application, a brief introduction of relevant technologies or terms of the present application is given as follows.

First, network slicing

Currently, the 3GPP standard defines network slice selection assistance information (network slice selection assistance information, NSSAI) to identify a network slice. On the radio access network (radio access network, RAN) side, the NSSAI can be used to identify the slice type and provide services. Each NSSAI can include a set of single network slice selection assistance information (single network slice selection assistance information, S-NSSAI), and each S-NSSAI can include a slice/service type (slice/servive type, SST) and a slice identifier ( slice differentiator, SD).

Among them, SST is mandatory information, which is used to represent the functions and services of the network slice. Generally, the SST can occupy 8 bits, and its value is 0-255, wherein 0-127 can represent a standardized SST, and 128-255 can represent an SST specified by an operator. In the fifth generation (5th generation, 5G) mobile communication technology, the standardized SST is shown in Table 1. Standardizing the SST facilitates mutual cooperation between global operators. Specifically, different operators use a set of unified standards to support slice roaming more efficiently.

Table 1

SD is optional information, which is used to further subdivide network slice subclasses for various requirements under the same SST. Typically, SD can occupy 24 bits.

Second, the existing slice co-construction and sharing architecture

FIG. 1 shows an existing slice co-construction and sharing architecture. Wherein, a network slice includes a wireless network sub-slice, a bearer network sub-slice and a core network sub-slice. When a user of operator A accesses the shared base station of operator A, the data reaches the Internet or service network of operator A via the access network, bearer network and core network of operator A; When the base station of B is shared, the data reaches the Internet or service network of operator A via the access network of operator B, the bearer network of operator B, the bearer network of operator A, and the core network of operator A. Similarly, when a user of operator B accesses the shared base station of operator B, the data reaches the Internet or service network of operator B via the access network, bearer network, and core network of operator B; When entering the shared base station of operator A, the data reaches the Internet or service network of operator B via the access network of operator A, the bearer network of operator A, the bearer network of operator B, and the core network of operator B. That is to say, users of operator A can use the access network and bearer network of operator B, and users of operator B can also use the access network and bearer network of operator A, but the core network cannot be shared.

In the co-construction and sharing scenario, as described in the background, the operator who builds the network slice may be different from the operator who uses the network slice. In fact, the brand and operation of operators remain independent, and there is still a certain degree of competition in the user market. However, when the users of operator B access the access network equipment of operator A, good cooperation between operators is required to ensure the best user experience. This kind of contradiction urgently requires standardization of management processes and communication between operators. docking process.

The network slicing management method provided by the embodiment of the present application will be described in detail below with reference to FIG. 2 .

As shown in Figure 3, it is a network slice management method provided by the embodiment of the present application, the method includes the following steps:

S301. The control device sends first network slicing parameters to the first network slicing management function network element of the first network and the second network slicing management function network element of the second network, wherein the first network slicing parameters are used to deploy the first network slicing parameter. For network slicing, the first network is a network that undertakes the construction of a shared access network, and the second network is a network that uses the shared access network. Correspondingly, the first network element with the network slice management function receives the first network parameter from the control device, and the second network element with the network slice management function receives the first network parameter from the control device.

Exemplarily, the control device in this embodiment of the application may adopt a federated learning algorithm. The federated learning algorithm can train a complete prediction model by training the weights. The parameters of the model can be encrypted and exchanged with the information of the first network or the second network, thereby coordinating the business requirements of the network slicing contractor and the sharing party using the network slicing. By analyzing the service requirements of network slicing, the control device can design corresponding network slicing parameters to complete the planning of new network slicing. Among them, the encrypted exchange can guarantee the data privacy of the contractor and the sharer. In addition, the control device can also manage and maintain the protocol for sharing network slices between the builder and the sharer, such as modifying the current protocol.

As shown in FIG. 4 , the control device may include a database (data base, DB), a data analysis function (dataanalytics function, DAF), and a coordination and management function (coordination&management, C&M). The functions of each module are introduced as follows:

The DB is used to store the deployment information of network slices and related historical information during processing, so that DAF can perform intelligent analysis and increase the flexibility to respond to business needs.

DAF is used to provide data analysis specific to network slices. DAF can send the analysis results of network slices to other modules for scheduling or management. In addition, DAF can use federated learning algorithms to improve the ability to dynamically plan network slices while ensuring data privacy.

C&M can process requests related to network slicing, such as access requests, parameter modification requests, or query requests, according to the analysis results fed back by the DAF.

Exemplarily, the network element with network slice management function may be a network slice management function (network slice management function, NSMF). NSMF can be used for network slice instantiation management and orchestration. For example, NSMF can convert the resource configuration scheme of the network slice into the resource configuration scheme of each domain sub-slice, and transmit the resource configuration scheme of each domain sub-slice to the network slice subnet management function (network slice subnet management function, NSSMF). Among them, NSSMF can be used for the management and orchestration of sub-slices in each domain, including access network-network slice subnet management function (access network-network slice subnet management function, AN-NSSMF), transport network network slice subnet management function (transport network-network slice subnet management function, TN-NSSMF) and core network network slice subnet management function (core network-network slice subnet management function, CN-NSSMF).

Exemplarily, after step S301 is executed, on the first network side, the first NSMF and the first CN-NSSMF may interact as follows: the first NSMF sends the parameters of the core network sub-slice of the first network slice to the first CN-NSSMF . After receiving the parameters of the core network sub-slice of the first network slice from the first NSMF, the first CN-NSSMF completes the deployment of the core network sub-slice, and feeds back the deployment information of the core network sub-slice to the first NSMF.

Exemplarily, after step S301 is executed, on the first network side, the first NSMF and the first TN-NSSMF may interact as follows: the first NSMF sends parameters of the transport network sub-slice of the first network slice to the first TN-NSSMF , including NSSAI, wireless indoor baseband processing unit (building baseband unit, BBU) identifier, core network user plane function (user plane function, UPF) port number, and virtual local area network (virtual local area network, VLAN) port number. After receiving the parameters of the transport network sub-slice of the first network slice from the first NSMF, the first CN-NSSMF completes the deployment of the transport network sub-slice, and feeds back the deployment information of the transport network sub-slice to the first NSMF.
