[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The terms "first", "second" etc. in the embodiments of the present invention are used to distinguish similar objects, and need not be used to describe a specific order or sequential order. In addition, the terms "include" and "have" and any variation thereof are intended to cover non-exclusive inclusions, for example, the process, method, system, product or equipment comprising a series of steps or units need not be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment. In addition, "and / or" is used in the present application to represent at least one of the connected objects, such as A and / or B and / or C, which represents 7 situations including single A, single B, single C, and A and B all exist, B and C all exist, A and C all exist, and A, B and C all exist.

[0038] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0039] See also Figure 1 , Figure 1 It is a flow chart of the network slice construction method provided in an embodiment of the present invention. Figure 1 The network slice construction method shown can be executed by an orchestrator.

[0040] like Figure 1 The network slice construction method shown may include the following steps:

[0041] Step 101: Receive demand information sent by a user.

[0042] The network slice construction method provided in this embodiment can be applied to a network slice construction device. It should be noted that a network slice can be constructed by multiple physical hosts and multiple network devices through multiple links, wherein the physical host and the network device are connected through a link, or multiple physical hosts are connected through a link, or multiple network devices are connected through a link.

[0043] Among them, according to the different link performances, the links can be divided into secure links, isolated links and ordinary links. The above-mentioned secure links are links with security means, which can realize secure connections between link-connected devices, such as links with Internet Protocol Security (IPsec); the above-mentioned isolated links are links with isolated ports; the above-mentioned ordinary links are links that have neither security means nor isolated ports.

[0044] A preferred solution is that the above-mentioned network slice construction device can be a slice orchestration and manager (Management and Orchestration, MANO), and the above-mentioned slice orchestration and manager can be called an orchestrator. In order to clearly explain the technical solution, the solution is explained with the network slice construction device as the orchestrator.

[0045] An optional method for receiving the demand information sent by the user is that the user performs relevant operations on the terminal, and the user terminal sends the demand information to the orchestrator. The demand information includes the user name and the performance requirement information of the network slice.

[0046] For example, the requirement information is [government system, physical host, domestic equipment, secure connection], indicating that the user is a government system, and requires that the physical host in the slice be a domestic equipment, and that the link in the slice be a secure link.

[0047] Step 102: Search the information chain for device information that matches the demand information.

[0048] After receiving the demand information, the scheduler may query the information chain for device information matching the demand information, wherein the number of the device information is greater than one.

[0049] The device information refers to the device managed by the authentication network element. It should be understood that since the network slice is built by multiple physical hosts and multiple network devices through multiple links, the device information is the information of the physical host and / or network device, and the above-mentioned physical host and network device are managed by the authentication network element.

[0050] Optionally, the device information is uploaded to the information chain by the authentication network element, and the device information in the information chain further includes device parameter sub-information, device capability sub-information and device pricing sub-information.

[0051] In this embodiment, the device information is uploaded to the information chain by the authentication network element, and the authentication network element is a member that meets the requirements of the information chain. It should be understood that the above device information includes device parameter sub-information, device capability sub-information and device pricing sub-information.

[0052] The above-mentioned device parameter sub-information is used to characterize relevant parameters of the device. For example, the device parameter sub-information may include information such as device number, device name, manufacturer, place of origin, device network address, etc.

[0053] The above-mentioned device capability sub-information is used to characterize the relevant performance of the device. For example, the device capability sub-information may include the number and model of processor cores, memory size and model, operating system type, network service type and capability, database type and capability, and other information.

[0054] The above-mentioned device pricing sub-information is used to characterize the billing rules for using the device. For example, the device pricing sub-information may include information such as device number, device name, service name, charging cycle, service unit price, etc.

[0055] It should be noted that the device information exists in the information chain in the form of blocks. That is, the information chain includes multiple blocks, each of which represents the device information uploaded by an authentication network element.

[0056] For easier understanding, see Figure 2 , Figure 2 It is a structural schematic diagram of blocks in the network slicing construction method provided in an embodiment of the present invention.

[0057] like Figure 2 As shown, block 1 is a piece of device information uploaded to the information chain by the authentication network element 1 through the publishing node. It should be noted that the publishing node verifies the network element corresponding to the device information, and uploads the device information to the information chain when it is determined that the network element is an authentication network element.

[0058] like Figure 2 As shown, block 1 includes a block header and a block body, wherein the block header stores the header information of the block, and the header information may include the hash value of the previous block, the hash value of the current block body, and a timestamp, etc. The block body includes multiple device parameter sub-information, multiple device capability sub-information, and 1 device pricing sub-information, and each device parameter sub-information, each device capability sub-information, and each device pricing sub-information includes the name of the authentication network element.

[0059] Step 103: Generate N slice information according to the device information.

[0060] In this embodiment, the scheduler may generate N pieces of slice information according to the device information.

[0061] It should be noted that the above device information all refers to devices that meet user requirements, and the number of the above device information is greater than 1. One possible situation is that if only one network slice can be constructed based on the above device information, the value of N is 1. Another possible situation is that if multiple network slices can be constructed based on the above device information, the value of N is greater than 1.

[0062] Exemplarily, the slice information can be expressed in the form of [server 1, server 2, switch 2, switch 3, link 1, link 4], indicating that the network slice is composed of physical host 1, physical host 2, network device 2, network device 3, link 1 and link 4.

[0063] Step 104: Upload the N slice information to the information chain.

[0064] In this embodiment, the scheduler uploads N slice information to the information chain. It should be understood that each slice information contains the identifier of the user terminal to ensure that the user can query the N slice information in the information chain.

[0065] In the embodiment of the present invention, the corresponding device information is determined in the information chain based on the demand information sent by the user, ensuring that each device in the network slice can meet the user's needs; and N slice information is generated and uploaded to the information chain. In this way, the user can participate in the construction process of the entire network slice through the information chain, thereby ensuring that the devices in the network slice meet the user's communication service needs.

[0066] Optionally, after uploading the N slice information to the information chain, the method further includes:

[0067] Receive target slice information sent by the user based on the N slice information; build a network slice based on the device pointed to by the target slice information.

[0068] In this embodiment, the user can obtain N slice information in the information chain through the terminal, and send the target slice information to the scheduler. It should be noted that the above target slice information is one of the N slice information.

[0069] It should be understood that the slice information includes multiple device information, and the device information in the target slice information can be referred to as the target device information. As mentioned above, the device information points to the device managed by the authentication network element. The orchestrator can build a network slice based on the device pointed to by the target device information and deliver it to the user.

[0070] Optionally, uploading the slice information to the information chain includes:

[0071] The slice information and the billing information corresponding to the slice information are uploaded to the information chain.

[0072] It should be noted that each slice information includes M pieces of device information, where M is a positive integer. As described above, the device information includes device pricing sub-information, so one slice information includes M pieces of device pricing sub-information.

[0073] An optional implementation is to add the device pricing in M ​​device pricing sub-information to obtain billing information, which is used to characterize the fees that users need to pay when using the network slice constructed using the slice information.

[0074] It should be understood that the above-mentioned billing information includes the identification of the user terminal, so that the user can query the billing information in the information chain.

[0075] It should also be understood that the above billing information includes the service period and the service unit price. For example, the service period is 1 month and the service unit price is 2000, which means that the cost of the network slice corresponding to the billing information is 2000 yuan per month.

[0076] Users pay for the use of network slices based on billing information, including at least the following two methods:

[0077] The first is that when the user uses the network slice corresponding to the billing information for the first time, the user makes corresponding payment based on the target billing information.

[0078] The second is that after the user uses the network slice corresponding to the billing information for a period of time, he makes corresponding payment based on the target billing information.

[0079] In this embodiment, the orchestrator generates billing information based on the device pricing sub-information in the slice information, so that the user can query the price corresponding to the network slice on the information chain to meet the user's needs for different price levels.

[0080] Optionally, after receiving the target slice information sent by the user based on the slice information, the method further includes:

[0081] Based on the target slice information and the target billing information corresponding to the target slice information, a first contract is generated; and the first contract is uploaded to the transaction chain.

[0082] It should be noted that the target slice information includes L target device information, and the target device information includes target device sub-information; the above-mentioned target billing information is generated based on the target device pricing sub-information in the L target device information, and L is a positive integer.

[0083] In this embodiment, after receiving the target slice information sent by the user, the orchestrator generates a first contract according to the slice information and the target billing information, and uploads the first contract to the transaction chain.

[0084] It should be understood that after uploading the first contract to the transaction chain, the external fund manager will freeze part of the amount in the user's associated bank account, which is the same as the service unit price in the target billing information.

[0085] Optionally, after receiving the target slice information sent by the user based on the slice information, the method further includes:

[0086] Based on the authentication network element pointed to by the target slice information and the target billing information corresponding to the target slice information, a second contract is generated; and the second contract is uploaded to the transaction chain.

[0087] It should be noted that the target slice information includes L target device information, and the authentication network element pointed to by the above target slice information is the authentication network element associated with the L target device information.

[0088] It should be understood that after the user uses the network slice, or after the user uses the network slice for a cycle, the second contract is uploaded to the transaction chain, and the external fund manager transfers the amount to the device manager corresponding to the authentication gateway based on the target billing information.

[0089] For example, the equipment of the network slice is provided by the first authentication gateway and the second authentication gateway, and the service unit price of the equipment provided by the first authentication gateway and the service unit price of the equipment provided by the second authentication gateway can be obtained according to the target billing information. Then, after the second contract is uploaded to the transaction chain, the external funds management party transfers the corresponding amount to the first equipment management party corresponding to the first authentication gateway and the second equipment management party corresponding to the second authentication gateway.

[0090] For ease of understanding, the following examples are provided:

[0091] See also Figure 3 As shown in the figure, the device information pool includes a large amount of device information uploaded by the authentication gateway. The above device information is uploaded to the information chain after being verified by the publishing node. It should be noted that there are multiple publishing nodes.

[0092] A method for constructing a network slice provided in this embodiment is that a user sends demand information to an orchestrator, the orchestrator queries the device information in the information chain, generates multiple slice information and billing information corresponding to each slice information based on the demand information, and uploads the slice information and billing information to the information chain. The user determines the target slice information and target billing information by querying the information chain, and sends the target slice information and target billing information to the orchestrator. The orchestrator constructs a network slice according to the device pointed to by the target slice information.

[0093] After the network slice is built, the orchestrator will also generate a first contract for the user's bank account based on the target slice information and target billing information; and generate a second contract for each device manager based on the manager of each device in the network slice and the target billing information to manage the network slice.

[0094] The present invention also provides another method for constructing a network slice, please refer to the following embodiment.

[0095] Optionally, the method further comprises:

[0096] Receive customized slicing information sent by a user, where the customized slicing information includes K pieces of device information, where K is a positive integer; and build a network slice based on the K devices pointed to by the K pieces of device information.

[0097] In this embodiment, as described above, the information chain stores multiple blocks, each block representing device information uploaded by an authentication network element. The user terminal can download all device information stored in the information chain, determine the device information that meets the requirements, and form customized slice information based on the above device information.

[0098] An optional implementation is that after downloading all device information, the user terminal manually selects the device information, generates customized slice information based on part of the device information, and sends the customized slice information to the orchestrator.

[0099] Another optional implementation is that after downloading all device information, the user terminal can customize the selection algorithm, automatically generate customized slice information based on the user terminal's demand information, and send the customized slice information to the orchestrator, wherein the selection algorithm can filter all downloaded device information based on aspects such as device usage price, device security, or device processing capability.

[0100] After receiving the customized slicing information sent by the user, the orchestrator builds a network slice based on the K devices pointed to by the K device information in the customized slicing information.

[0101] Optionally, after constructing the network slice, the method further includes:

[0102] Generate customized billing information based on the device pricing sub-information in the K device information; upload the customized billing information and the customized slicing information to the information chain.

[0103] It should be noted that the customized slice information sent by the user includes K device information, and each device information includes device pricing sub-information. Customized billing information can be generated based on the K device pricing sub-information, and the above customized slice information and customized billing information can be uploaded to the information chain. Users can query the customized slice information and customized billing information in the information chain to trace the relevant information of the network slice.

[0104] In this embodiment, the user can query all device information on the information chain, independently select device information to form slice information, and then participate in the construction process of the entire network slice to personalize the network slice.

[0105] See also Figure 4 , Figure 4 This is another flow chart of the network slice construction method provided in an embodiment of the present invention. Figure 4 The network slice construction method shown can be executed by a terminal.

[0108] The network slice construction method provided in this embodiment can be executed by a terminal. The terminal sends user demand information to the orchestrator, and the above demand information is used to characterize the configuration requirements of the devices in the network slice to be constructed.

[0109] Step 202: query the information chain for N slice information uploaded by the scheduler based on the demand information.

[0110] It should be noted that the slice information uploaded by the orchestrator includes the identification information of the terminal. Therefore, the terminal can query the N slice information corresponding to the terminal in the information chain based on the identification information.

[0111] Step 203: Send the target slice information to the orchestrator, so that the orchestrator builds a network slice based on the device pointed to by the target slice information.

[0112] One possible situation is that when the value of N is 1, that is, there is only one slice information, the unique slice information is determined as the target slice information and sent to the arranger.

[0113] Another possible situation is that when the value of N is greater than 1, that is, there are multiple slice information, based on the user's instructions for the N slice information, the target slice information among the N slice information is determined and sent to the organizer.

[0114] For the orchestrator, after receiving the target slice information sent by the terminal, it builds a network slice based on the device pointed to by the target slice information.

[0115] Optionally, the method further comprises:

[0116] Send customized slicing information to the orchestrator, so that the orchestrator builds a network slice based on the K devices pointed to by the K device information in the customized slicing information.
