Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a network slicing management method and device, and a communication network. Background Art

[0002] Network slicing technology refers to virtualizing multiple isolated logical networks based on the physical network, flexibly allocating hardware resources, and networking on demand to meet the different needs of various businesses. When a new business needs to be launched and the current network cannot meet the needs of the new business, only a new network slice needs to be virtualized for the new business, without the need to build a new network, which improves the efficiency of launching new businesses.

[0003] In related technologies, the operator's integrated base station circuit scheduling work order triggers the configuration of network slices, and after the work order process, the equipment manufacturer is coordinated to manually configure the network slices. The equipment manufacturer manually determines the network slice resources and the equipment involved required for the business, and then configures the network slices.

[0004] However, currently, the network slice configuration of the service is usually rigidly designed manually, for example, all the planned network slices are configured for each application of the service, resulting in a waste of hardware resources. In addition, the work order process is usually time-consuming, resulting in low efficiency in manually determining the network slice requirements of the application and the equipment involved, which leads to low efficiency in the configuration of network slices. Summary of the invention

[0005] The present application provides a network slicing management method and device, and a communication network, which solves the problem of waste of hardware resources caused by network slicing configuration and low configuration efficiency of network slicing in related technologies, effectively avoiding the waste of hardware resources. At the same time, the configuration of network slicing does not require human participation but is performed automatically, without labor costs, and can quickly configure network slicing based on the network slicing requirements of the application, thereby realizing the rapid launch of network slicing.

[0006] In a first aspect, the present application provides a method for managing network slices, the method comprising: when an application corresponding to a target network slice is launched, if a first network sub-slice of the target network slice is not configured in a first network, determining configuration information of the first network sub-slice, the target network slice being indicated by the target network slice information when the application is launched; sending the configuration information of the first network sub-slice to a device of the first network, the configuration information of the first network sub-slice being used to configure the first network sub-slice.

[0007] The sub-slice in the first network used to form the target network slice is the first network sub-slice. The configuration information may be a configuration script, which includes a configuration command line, and the configuration command line may be a man-machine language (MML) command line.

[0008] In the related technology, the configuration of network slices is rigidly designed. When new network equipment (such as wireless sites or bearer network equipment, etc.) is added to the communication network, it is necessary to reconfigure and deploy the network slice of each application. The configuration and deployment process is complex and time-consuming.

[0009] In the embodiment of the present application, the card opening and account opening of the device where the application runs and the application side online trigger the configuration process of the network slice. The network slice requirements of the application are perceived by the application side online. When the network slice required by the application is not configured in the network, the corresponding network sub-slice is automatically configured, rather than rigidly designing the network slice configuration of the application, which can effectively avoid the waste of hardware resources. At the same time, the configuration of the network slice does not require manual participation but is automatic, without labor costs. It can quickly configure the network slice based on the network slice requirements of the application, and realize the rapid online of the network slice. When a new device is added to the communication network, there is no need to reconfigure and deploy the network slice of each application, which simplifies the configuration process of the network slice.

[0010] In a possible implementation, the method also includes: receiving a first message reported by a device of the first network, the first message being used to indicate that the first network sub-slice is not configured in the first network; wherein the first message is determined through a registration signaling process or a session establishment process of the application, and the registration signaling process or the session establishment process carries the target network slice information.

[0012] The second network cannot perceive the upper layer application business. The device of the first network can also perceive whether the target network slice indicated by the target network slice information is configured in the second network through the signaling process.

[0013] The beneficial effect is that whether the network slice is configured in the network is perceived through the signaling process of the application, and the second network cannot perceive the upper-layer application service, and therefore cannot perceive whether the target network slice is configured in the second network. Through this process, the first network perceives whether the target network slice is configured in the second network, and when the configuration is not completed, the management device of the first network notifies the management device of the second network. In this way, even if the second network cannot perceive the upper-layer application service, it can meet the configuration requirements of the network sub-slice in the second network.

[0014] In a possible implementation manner, the transmitting the second message to the management device of the second network includes: sending the second message to the system platform, so that the system platform sends the second message to the management device of the second network.

[0015] In a possible implementation manner, the first network is an access network or a core network, and the second network is a bearer network.

[0016] In a possible implementation, the method also includes: receiving status information reported by a device of the first network, the status information being used to indicate a usage status of each network sub-slice in the first network; and monitoring each network sub-slice in the first network according to the status information.

[0017] In a possible implementation, monitoring each network sub-slice in the first network according to the status information includes: determining that a third network sub-slice in the first network meets a deletion condition according to the status information; determining deletion information of the third network sub-slice; and sending deletion information of the third network sub-slice to a device of the first network, wherein the deletion information of the third network sub-slice is used to delete the third network sub-slice.

[0018] The deletion condition includes but is not limited to: no service exists within a preset time period. The deletion information may be a deletion script, which includes a deletion command line, and the deletion command line may be an MML command line.

[0019] In a possible implementation, monitoring each network sub-slice in the first network according to the status information includes: determining that a fourth network sub-slice in the first network does not meet business requirements according to the status information; determining maintenance information of the fourth network sub-slice; and sending maintenance information of the fourth network sub-slice to a device of the first network, wherein the maintenance information of the fourth network sub-slice is used to reconfigure the fourth network sub-slice.

[0020] Failure to meet service requirements includes but is not limited to: network sub-slicing is congested, network sub-slicing does not meet the bandwidth or latency requirements of the service, etc. The maintenance information can be a maintenance script, which includes a maintenance command line, and the maintenance command line can be an MML command line.

[0024] In a possible implementation manner, the transmitting the fourth message to the management device of the second network includes: sending the fourth message to the system platform, so that the system platform sends the fourth message to the management device of the second network.

[0025] In the related technology, the operator's comprehensive base station circuit scheduling work order triggers the deletion and maintenance of network slices, and after the work order process, the equipment manufacturer is coordinated to manually delete and maintain the network slices. The network slices in the communication network are under static management. In this way, some network slices do not meet business needs, and some network slices have no business, resulting in unreasonable allocation of hardware resources and waste of hardware resources. For example, radio bearer (RB) resource reservation occupies wireless resources and transmission time slot resources.

[0026] In the embodiment of the present application, each network sub-slice in the first network and the second network is automatically monitored according to the status information reported by the device of the first network. The network sub-slice can be deleted and the hardware resources occupied by the network sub-slice can be recovered according to the usage status of the network sub-slice, and the network sub-slice can be maintained according to the usage status of the network sub-slice, so as to realize the dynamic adjustment and management of all network sub-slices in the communication network, accurately adapt to the differentiated business requirements and service quality (quality of service, QOS) requirements of the application, and effectively improve the utilization rate of the hardware resources of the communication network.

[0027] In a possible implementation, determining the configuration information of the first network sub-slice includes: determining the resource parameters corresponding to the first network sub-slice according to the resource parameter mapping relationship and the target network slice information, the resource parameter mapping relationship including: a mapping relationship between the network slice information of a preset network slice and the resource parameters corresponding to each network sub-slice included in the network slice; generating the configuration information of the first network sub-slice based on the resource parameters corresponding to the first network sub-slice.

[0028] The beneficial effect is that the network slice information is used as the only entry parameter, and through the resource parameter mapping relationship, it can be mapped to the configuration of each network sub-slice included in each network slice and the hardware resource pool, and the implementation process is simple. Therefore, the unique network slice can be determined and located through the network slice information and mapped with the network element, so as to achieve accurate management of the network element hardware resources corresponding to the network slice, for example, accurately locate the corresponding network element hardware resources when the network slice needs maintenance.

The access network element may be a macro base station, a micro base station or an indoor station, a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific equipment form adopted by the access network element.

[0099] The device of the server network is the server, which can be located in the cloud or locally. It can be a physical device or a virtual device such as a virtual machine, container, etc., and has wireless communication capabilities.

[0100] Network slicing is an end-to-end network slice, which is formed by combining sub-slices of each network between end-to-end. In a communication network, each network slice has different network functions and can adapt to different types of business requirements, so that it can be flexibly applied to different network application scenarios. Business requirements may include: latency, bandwidth, security, and reliability.

[0101] For example, 5G networks can currently support three scenarios: enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra reliable low latency communication (uRLLC). Operators can virtualize an eMBB network slice based on hardware resources for mass Internet access services, and virtualize an mMTC network slice based on hardware resources for the needs of some manufacturers in vertical industries (such as smart meter reading needs).

[0102] Please refer to Figure 1 , Figure 1 A schematic diagram of a communication network structure provided in an embodiment of the present application is provided. Figure 1 Taking the 5G ToB dedicated network as an example, the communication network includes access network equipment, bearer network equipment, core network equipment, access network management equipment 101, bearer network management equipment 201 and core network management equipment 301.

[0103] like Figure 1 As shown, the access network equipment includes two base stations 102 and 103. The bearer network includes two bearer network subnets 202 and 203, each of which includes three routing devices (i.e., bearer network devices), which can be access layer box routers, integrated service bearer routers, and 5G core network customer edge (5G core network customer edge, 5GC CE) devices.

When NCE configures network slices, it can complete the automatic filling of Internet protocol (IP), virtual local area network (VLAN), equipment, port and circuit adjustment orders based on resource pools and established policies, thereby completing the network slice deployment of bearer network devices with one click.

[0105] Figure 1 In the concept of southbound network, the equipment of any network can also be called the southbound network element of the management equipment of the network. Correspondingly, the management equipment of any network can also be called the northbound equipment of the equipment of the network. Southbound refers to the interface connecting the lower-level system and equipment, which is used to implement functions such as issuing services and collecting performance indicator data. Northbound refers to the interface connecting the upper-level system and equipment.

[0106] Optionally, the communication network may further include an upper-layer system platform, and a communication connection is established between the system platform and the management device of each network. When the management devices of each network are independent of each other, information exchange between the management devices of all networks can be achieved through the system platform. The system platform may include a network management system (NMS).

[0107] For example, please refer to Figure 2 , Figure 2 A schematic diagram of another communication network structure provided in an embodiment of the present application, in Figure 1 On the basis of, the communication network also includes a system platform 401, and the system platform 401 has established communication connections with the management devices 101, 201 and 301.

[0108] It should be noted that the above Figure 1 and Figure 2 The structure is only an example and does not constitute a limitation on the structure of the communication network. For example, the communication network may also include a terminal device and a server that establishes a communication connection with the access network.

[0109] The campus end-to-end also includes terminals and campus servers (belonging to campus applications and IT networks). Terminals are slice users, and campus servers generally do not support slice deployment and cannot be managed in wireless, NCE IP and core network management. These two are not within the scope of end-to-end slice management.

[0110] The embodiment of the present application provides a network slice management method, which can realize the automatic management of network slices. The method can be applied to communication networks, such as Figure 1 or Figure 2 Please refer to the communication network shown. Figure 3 , Figure 3 A flowchart of a network slice management method provided in an embodiment of the present application is provided. Figure 3 The method is applied to a network management device as an example for explanation. The network managed by the management device can perceive upper layer application services, such as access network and core network. The method may include the following process:

[0111] 501. When an application corresponding to a target network slice goes online, if a first network sub-slice of the target network slice is not configured in the first network, the configuration information of the first network sub-slice is determined, and the target network slice is indicated by the target network slice information when the application goes online.

[0112] The first network can perceive upper layer application services, and may be an access network or a core network.

[0113] The application can be a terminal device application. In the embodiment of the present application, the terminal devices can be grouped in advance, and different terminal groups are mapped to different network slices. The network slice mapped to the group where the terminal device is located is the network slice corresponding to the terminal device application. The network slices supported by the communication network are pre-set and can be dynamically changed later. Different terminal devices have different QOS for the communication network, so the terminal devices can be grouped according to the business demand QOS.

[0114] Parameters that characterize the service demand QOS include but are not limited to: jitter, latency, packet loss rate, bit error rate, signal-to-noise ratio, etc. For example, the large bandwidth, low latency, and large connection demand groups obtained according to the QOS grouping can be divided into this group for terminal devices running on the application side, such as camera applications, coal mining remote control applications, and various sensor data backhaul applications.

[0115] For example, see the aforementioned Figure 1 and Figure 2 , Figure 1 and Figure 2 Also shown are multiple terminal device groups connected to the access network and thus accessing the communication network, including: a mobile phone group, a camera group, a sensor group (such as a mine pressure sensor), and a vehicle terminal group. Among them, the mobile phone group maps network slice 1, the camera group maps network slice 2, the sensor group maps network slice 3, and the vehicle terminal group maps network slice N.

[0116] The terminal device can open a card and an account for the corresponding network slice in the network element of the communication network, for example, opening a card and an account in the core network element UDM through the access network. The card opening and account opening can be opening a user identity module (SIM) card and opening an account online. The SIM card carries the slice information when opening an account online. The slice information is used to indicate the network slice corresponding to the terminal device, for example, it can be the slice identity document (ID). See Figure 1 and Figure 2 , taking the camera group as an example, a card is opened for the camera in the network element of the communication network, and network slice 2 is opened. The ID of the network slice may be the same as or different from the ID of the network sub-slice it includes. The embodiment of the present application does not limit this, as long as the correspondence between the network slice and the network sub-slice it includes is accurate.

[0117] Taking the target network slice for opening a card and an account of a terminal device as an example, after the terminal device is turned on, the application corresponding to the target network slice goes online and enters the registration signaling process. After the registration is completed, the application enters the session establishment process for service transmission. Both the registration signaling process and the session establishment process carry the target network slice information, and the target network slice information indicates the target network slice. Taking the communication network as a 5G network as an example, the registration process is the user registration signaling process of the 3GPP wireless communication protocol, and the session establishment process is the packet data unit (PDU) establishment process.

[0118] The device of the first network can obtain the target network slice information by obtaining the signaling process of the newly launched application, and sense whether the target network slice indicated by the target network slice information is configured in the first network through the signaling process. As can be seen from the above description, the target network slice refers to an end-to-end network slice, which is composed of sub-slices of each network in the communication network.

[0119] In the embodiment of the present application, the sub-slice used to constitute the target network slice in the first network is the first network sub-slice, and the device of the first network senses whether the target network slice is configured in the first network, that is, senses whether the first network sub-slice is configured in the first network. If the first network sub-slice of the target network slice is not configured in the first network, the device of the first network notifies the management device of the first network, and the management device of the first network determines that the first network sub-slice is not configured in the first network.

[0120] The configuration information may be a configuration script, which includes a configuration command line, and the configuration command line may be an MML command line.

[0121] In one implementation, the configuration information may be pre-generated, and the management device of the first network directly obtains the pre-generated configuration information. In another implementation, a resource parameter mapping relationship is preset in the first network, and the resource parameter mapping relationship includes: a mapping relationship between the network slice information of the preset network slice and the resource parameters corresponding to each network sub-slice included in the network slice. The management device of the first network determines the resource parameters corresponding to the first network sub-slice based on the resource parameter mapping relationship and the target network slice information. Then, based on the resource parameters corresponding to the first network sub-slice, the configuration information of the first network sub-slice is generated. By way of example, the management device of the first network may generate the configuration information of the first network sub-slice based on the resource parameters corresponding to the first network sub-slice through a script configurator.

[0122] The resource parameters corresponding to the network sub-slice characterize the configuration of the network sub-slice and the resource pool used. The resource parameter mapping relationship can be reflected in the form of a table. For example, please refer to Table 1, which shows the resource parameter mapping relationship. Table 1 takes the network slice information as the slice ID and the communication network includes the access network, the bearer network and the core network as an example for explanation. As shown in Table 1, for network slice ID1, the resource parameters of the network sub-slice in the access network include: gNBCuNgID1, user plane host (Userplanehost) ID1, virtual routing androrwarding (virtual routing androrwarding, VRF) 1, VLAN1, etc. The resource parameters of the network sub-slice in the bearer network include: the sub-interface IP address of the network sub-slice, the loopback address of the network sub-slice, the virtual private network (virtualprivate network, VPN) name, etc. The resource parameters of the network sub-slice in the core network include: network slice instance (network slice instance, NSI), VRF, routing design, etc. of the network sub-slice service.

[0123] Table 1

[0124]

[0125] The resource parameter mapping relationship shown in the above Table 1 is only an example and does not constitute a limitation on the resource parameter mapping relationship.

[0126] The embodiment of the present application uses the network slice information as the only entry parameter, and through the resource parameter mapping relationship, it can be mapped to the configuration of each network sub-slice included in each network slice and the hardware resource pool, and the implementation process is simple. Therefore, the unique network slice can be determined and located through the network slice information and mapped with the network element, so as to achieve accurate management of the network element hardware resources corresponding to the network slice, for example, accurately locate the corresponding network element hardware resources when the network slice needs maintenance.

[0127] The management device of the first network may also send an alarm message to the network management device client of the communication network, and the alarm message is used to prompt the first network sub-slice of the target network slice that is not configured in the manual first network. At this time, the process 501 may also be performed with manual participation, and the management device of the first network may determine the configuration information of the first network sub-slice when receiving the manual configuration operation.

[0128] 502. Send configuration information of the first network sub-slice to the device of the first network, where the configuration information of the first network sub-slice is used to configure the first network sub-slice.

[0129] After completing the configuration of the first network sub-slice, the application corresponding to the target network slice re-registers for access, triggering the user plane session establishment process. The newly established session bearer uses the hardware resources of each network sub-slice included in the target network slice. For example, the hardware resources corresponding to the access network sub-slice, bearer network sub-slice, and core network sub-slice included in the target network slice are used.

[0130] In summary, the network slice management method provided in the embodiment of the present application, when the application corresponding to the target network slice is launched, if the first network sub-slice of the target network slice is not configured in the first network, determines the configuration information of the first network sub-slice, and then sends the configuration information of the first network sub-slice to the device of the first network. The configuration information of the first network sub-slice is used to configure the first network sub-slice. The card opening and account opening of the device where the application runs and the online application trigger the configuration process of the network slice. The network slice requirements of the application are perceived through the online application side. When the network slice required by the application is not configured in the network, the corresponding network sub-slice is automatically configured, instead of rigidly designing the network slice configuration of the application, which can effectively avoid the waste of hardware resources. At the same time, the configuration of the network slice does not require manual participation but is performed automatically, without labor costs, and can quickly configure the network slice based on the network slice requirements of the application, realizing the rapid launch of the network slice.

[0131] Please refer to Figure 4 , Figure 4 A flowchart of another network slice management method provided in an embodiment of the present application is provided. Figure 4The method is applied to a network management device as an example for explanation. The network managed by the management device can perceive upper layer application services, such as access network and core network. The method may include the following process:

[0132] 601. When an application corresponding to a target network slice goes online, if a first network sub-slice of the target network slice is not configured in the first network, the configuration information of the first network sub-slice is determined, and the target network slice is indicated by the target network slice information when the application goes online.

[0133] This process may refer to the aforementioned process 501, and the embodiment of the present application will not be described in detail here.

[0134] 602. Send configuration information of the first network sub-slice to the device of the first network, where the configuration information of the first network sub-slice is used to configure the first network sub-slice.

[0135] This process may refer to the aforementioned process 502, and the embodiment of the present application will not be described in detail here.

[0136] 603. When the second network sub-slice of the target network slice is not configured in the second network, a first message is transmitted to a management device of the second network, where the first message is used to determine configuration information of the second network sub-slice and to send the configuration information of the second network sub-slice to a device of the second network, where the configuration information of the second network sub-slice is used to configure the second network sub-slice.

[0137] The second network cannot perceive the upper layer application service, which may be a bearer network. The first message may carry slice information of the target network slice or sub-slice information of the second network sub-slice.

[0138] The device of the first network can also sense whether the target network slice indicated by the target network slice information is configured in the second network through the signaling process. In an embodiment of the present application, the sub-slice used to constitute the target network slice in the second network is the second network sub-slice. If the second network sub-slice of the target network slice is not configured in the first network, the device of the first network notifies the management device of the first network, and the management device of the first network determines that the second network sub-slice is not configured in the second network.

[0139] If the management device of the first network can communicate directly with the management device of the second network, the management device of the first network can directly send the first message to the management device of the second network. Figure 2 The communication network shown in the figure), the management device of the first network and the management device of the second network communicate through the system platform, then the management device of the first network can send a first message to the system platform, and the system platform sends a first message to the management device of the second network.

[0140] For the related description of this process, please refer to the aforementioned process 501, and the embodiment of the present application will not be described in detail here.

[0141] The management device of the first network may transmit the first message to the management device of the second network by means of file transfer, or may transmit the first message to the management device of the second network by means of a network management device client of the communication network. The embodiment of the present application does not limit the transmission method of the first message.

[0142] Whether the network slice is configured in the network is perceived through the signaling process of the application, and the second network cannot perceive the upper-layer application service, and therefore cannot perceive whether the target network slice is configured in the second network. Through this process 603, the first network perceives whether the target network slice is configured in the second network, and when the configuration is not completed, the management device of the first network notifies the management device of the second network. In this way, even if the second network cannot perceive the upper-layer application service, it can meet the configuration requirements of the network sub-slice in the second network.

[0143] 604. Receive status information reported by a device of the first network, where the status information is used to indicate the usage status of each network sub-slice in the first network.

[0144] The status information can also be used to indicate the usage status of each network sub-slice in the second network.

[0145] 605. Monitor each network sub-slice in the first network according to the status information.

[0146] The management device of the first network can determine whether there is a network sub-slice that meets the deletion condition based on the status information, and the deletion condition includes but is not limited to: there is no business within a preset time. Assuming that it is determined based on the status information that the third network sub-slice in the first network meets the deletion condition, the deletion information of the third network sub-slice can be determined, and the deletion information of the third network sub-slice can be sent to the device of the first network. The deletion information of the third network sub-slice is used by the device of the first network to delete the third network sub-slice and reclaim the hardware resources occupied by the third network sub-slice.

[0147] The management device of the first network can also determine whether there is a network sub-slice that does not meet the service requirements based on the status information. The non-satisfaction of service requirements includes but is not limited to: congestion in the network sub-slice, the network sub-slice does not meet the bandwidth or latency requirements of the service, etc. Assuming that it is determined based on the status information that the fourth network sub-slice in the first network does not meet the service requirements, the maintenance information of the fourth network sub-slice can be determined, and the maintenance information of the fourth network sub-slice can be sent to the device of the first network. The maintenance information of the fourth network sub-slice is used by the device of the first network to reconfigure the third network sub-slice.

[0148] The deletion information may be a deletion script, which includes a deletion command line, which may be an MML command line. The maintenance information may be a maintenance script, which includes a maintenance command line, which may be an MML command line.

[0149] In one implementation, the deletion information or maintenance information may be pre-generated, and the management device of the first network directly obtains the pre-generated deletion information or maintenance information. In another implementation, the management device of the first network determines the resource parameters corresponding to the first network sub-slice based on the aforementioned resource parameter mapping relationship and the target network slice information. Then, based on the resource parameters corresponding to the first network sub-slice, the deletion information or maintenance information of the first network sub-slice is generated. The resource parameter mapping relationship can refer to the aforementioned process 501, and the embodiments of the present application are not described in detail here.

[0150] The above is explained by taking the example of the management device of the first network actively sending deletion information or maintenance information. Optionally, the process can also be performed with manual participation. For example, when the management device of the first network determines that the third network sub-slice meets the deletion conditions, it can send a deletion prompt message to the network management device client of the communication network, and the deletion prompt message is used to prompt whether to manually delete the third network sub-slice. Afterwards, when a manual deletion operation is received through the network management device client, the deletion information of the third network sub-slice is sent to the device of the first network.

[0151] For another example, when the management device of the first network determines that the fourth network sub-slice does not meet the service requirements, it sends maintenance prompt information to the network management device client, and the maintenance prompt information is used to prompt manual reconfiguration of the fourth network sub-slice or verification of the hardware resources of the fourth network sub-slice. When a manual maintenance operation is received through the network management device client, the maintenance information of the fourth network sub-slice is sent to the device of the first network.

[0152] In an embodiment of the present application, the status information can also be used to indicate the usage status of each network sub-slice in the second network. The management device of the first network can monitor each network sub-slice in the second network according to the status information.

[0153] The management device of the first network can determine whether there is a network sub-slice in the second network that meets the deletion condition based on the status information. Assuming that it is determined based on the status information that the fifth network sub-slice in the second network meets the deletion condition, a second message can be transmitted to the management device of the second network. The second message is used for the management device of the second network to determine the deletion information of the fifth network sub-slice, and to send the deletion information of the fifth network sub-slice to the device of the second network. The deletion information of the fifth network sub-slice is used for the device of the second network to delete the fifth network sub-slice and reclaim the hardware resources occupied by the fifth network sub-slice.

[0154] The management device of the first network can also determine whether there is a network sub-slice in the second network that does not meet the service requirements based on the status information. Assuming that it is determined based on the status information that the sixth network sub-slice in the second network does not meet the service requirements, a third message can be transmitted to the management device of the second network. The third message is used by the management device of the second network to determine the maintenance information of the sixth network sub-slice and send the maintenance information of the sixth network sub-slice to the device of the second network. The maintenance information of the sixth network sub-slice is used by the device of the second network to reconfigure the sixth network sub-slice.

[0155] The aforementioned process is described by taking the example that the management device of the second network actively sends deletion information or maintenance information after receiving the third message. Optionally, the management device of the second network may also send maintenance information or deletion information to the device of the second network under manual control. This process may refer to the aforementioned process that the management device of the first network sends maintenance information or deletion information to the device of the first network under manual control. The embodiments of the present application will not be described in detail here.

[0156] The transmission process and method of the second message or the third message can refer to the aforementioned first message. The transmission process can be sent directly from the management device of the first network to the management device of the second network, or it can be transmitted through the system platform. The embodiments of the present application will not be elaborated here.

[0157] The usage status of the network slice is also perceived through the signaling process of the application, and the second network cannot perceive the upper-layer application service, and therefore cannot perceive the usage status of each network sub-slice in the second network. In an embodiment of the present application, the first network perceives the usage status of each network sub-slice in the second network. When there is a network sub-slice that needs to be deleted or maintained in the second network, the management device of the first network notifies the management device of the second network. In this way, even if the second network cannot perceive the upper-layer application service, it can meet the deletion or maintenance requirements of the network sub-slices in the second network.

[0158] The above embodiment is explained by taking the management device of the first network and the management device of the second network as an example in which they are independently set. When the management device of the first network and the management device of the second network are integrated into one device, there is no need to transmit information, for example, when the second network sub-slice is not configured in the second network, the management device of the second network is notified.

[0159] In summary, the network slice management method provided in the embodiment of the present application, when the application corresponding to the target network slice is launched, if the first network sub-slice of the target network slice is not configured in the first network, determines the configuration information of the first network sub-slice, and then sends the configuration information of the first network sub-slice to the device of the first network. The configuration information of the first network sub-slice is used to configure the first network sub-slice. The card opening and account opening of the device where the application runs and the online application trigger the configuration process of the network slice. The network slice requirements of the application are perceived through the online application side. When the network slice required by the application is not configured in the network, the corresponding network sub-slice is automatically configured, instead of rigidly designing the network slice configuration of the application, which can effectively avoid the waste of hardware resources. At the same time, the configuration of the network slice does not require manual participation but is performed automatically, without labor costs, and can quickly configure the network slice based on the network slice requirements of the application, realizing the rapid launch of the network slice.

[0160] Furthermore, when the second network sub-slice of the target network slice is not configured in the second network, a first message may be transmitted to the management device of the second network, and the first message is used to determine the configuration information of the second network sub-slice, and to send the configuration information of the second network sub-slice to the device of the second network, and the configuration information of the second network sub-slice is used to configure the second network sub-slice. The second network cannot perceive whether the target network slice has been configured in the second network, and the first network perceives whether the target network slice has been configured in the second network, and notifies the management device of the second network when the configuration is not completed. In this way, even if the second network cannot perceive the upper-layer application services, it can meet the configuration requirements of the network sub-slices in the second network.

[0161] In addition, each network sub-slice in the first network and the second network can be automatically monitored based on the status information reported by the devices of the first network. The network sub-slice can be deleted and the hardware resources occupied by the network sub-slice can be reclaimed based on the usage status of the network sub-slice. The network sub-slice can also be maintained based on the usage status of the network sub-slice, realizing dynamic adjustment and management of all network sub-slices in the communication network, accurately adapting to the differentiated QOS requirements of applications, and effectively improving the utilization rate of hardware resources in the communication network.

[0162] Please refer to Figure 5 , Figure 5 A flowchart of another network slice management method provided in an embodiment of the present application is provided. Figure 5 The method is described by taking the application of the method to a network device as an example. The network device is capable of perceiving upper layer application services, such as devices of access networks and core networks. The method may include the following processes:

[0163] 701. Obtain the target network slice information carried by the signaling process of the newly launched application, where the target network slice information indicates the target network slice, and the signaling process includes a registration signaling process and / or a session establishment process.

[0164] Taking the registration signaling process of the 5G network as an example, the target network slice information can be the single network slice selection assistance information (S-NSSAI) carried in the registration signaling process of the application.

[0165] One S-NSSAI can be associated with one or more network slice instances, and one network slice instance can be associated with one or more S-NSSAIs. For example, the S-NSSAI values ​​associated with UeMBB slice 1 and UeMBB slice 2 are both 0x01000000. eMBB+mMTC slice 4 can provide services for both eMBB type services and mMTC services. Therefore, it is both an eMBB type network slice and an mMTC type network slice, and the associated S-NSSAI values ​​are 0x01000000 and 0x02000000 respectively.

[0166] When the terminal device where the application is located registers to a Public Land Mobile Network (PLMN), it sends a registration request message to the RAN. If the terminal device stores the configured NSSAI (configured NSSAI) of the PLMN or the allowed NSSAI (allowed NSSAI) of the access type of the PLMN, the application's network attached storage (NAS) registration request message and AN message will carry a requested NSSAI (requested NSSAI) message or a globally unique AMF identifier (globally unique AMF identifier, GUAMI). The requested NSSAI message or GUAMI includes the S-NSSAI of the network slice that the application wishes to register. RAN selects the initial AMF (initial AMF) based on the GUAMI or requested NSSAI message.

[0167] If the application does not provide the requested NSSAI message and GUAMI in the AN message, the RAN shall send the Registration Request message from the application to the default AMF.

[0168] Through the aforementioned registration signaling process, the management device of the core network and the management device of the access network can obtain the target network slice information (ie, NSSAI), and then the core network or access network can transmit the target network slice information to the management device of the bearer network.

[0169] After the registration signaling process is completed, the application will perform the session establishment process. If the session establishment process fails, the core network will obtain the target network slice information through the session establishment process, and transmit the target network slice information to the access network management device and the bearer network management device through the core network management device. In this way, the access network management device and the bearer network management device obtain the target network slice information.

[0170] 702. When it is determined through the signaling process that the first network sub-slice of the target network slice is not configured in the first network, a first message is reported to the management device of the first network, and the first message is used to instruct the management device of the first network to determine the configuration information of the first network sub-slice.

[0171] Taking the communication network as a 5G network as an example, if the first network is a core network, when the user registration signaling process fails or the PDU establishment process fails, it is determined that the first network sub-slice of the target network slice is not configured in the first network. If the first network is an access network or a bearer network, as described in the aforementioned process 701, when the PDU establishment process fails, the management device of the core network transmits the target network slice information to the management device of the first network. The management device of the first network maintains the existing slice configuration, and can determine whether the first network sub-slice of the target network slice is configured in the first network based on the target network slice information and the existing slice configuration.

[0172] 703. Receive configuration information of the first network sub-slice sent by the management device of the first network.

[0173] 704. Configure the first network sub-slice according to the configuration information of the first network sub-slice.

[0174] The device of the first network configures the hardware resources of the first network to provide the first network sub-slice according to the configuration information of the first network sub-slice.

[0175] Please refer to Figure 6 , Figure 6 A flowchart of another network slice management method provided in an embodiment of the present application is provided. Figure 6 The method is described by taking the application of the method to a network device as an example. The network device is capable of perceiving upper layer application services, such as devices of access networks and core networks. The method may include the following processes:

[0176] 801. Obtain the target network slice information carried by the signaling process of the newly launched application, where the target network slice information indicates the target network slice, and the signaling process includes a registration signaling process and / or a session establishment process.

[0177] This process may refer to the aforementioned process 701, and the embodiment of the present application will not be described in detail here.

[0178] 802. When it is determined through the signaling process that the first network sub-slice of the target network slice is not configured in the first network, a first message is reported to the management device of the first network, and the first message is used to instruct the management device of the first network to determine the configuration information of the first network sub-slice.

[0179] This process may refer to the aforementioned process 702, and the embodiment of the present application will not be described in detail here.

[0180] 803. Receive configuration information of the first network sub-slice sent by the management device of the first network.

[0183] This process may refer to the aforementioned process 704, and the embodiment of the present application will not be described in detail here.

[0184] 805. When it is determined through the signaling process that the second network sub-slice in which the target network slice is not configured is in the second network, a second message is reported to the management device of the first network, so that the management device of the first network transmits a third message to the management device of the second network. The third message is used to determine the configuration information of the second network sub-slice, and to send the configuration information of the second network sub-slice to the device of the second network, and the configuration information of the second network sub-slice is used to configure the second network sub-slice.

[0185] The process by which the device of the first network determines whether the second network sub-slice is configured in the second network through a signaling process can refer to the aforementioned process of determining whether the first network sub-slice is configured in the first network, and the embodiments of the present application will not be repeated here.

[0186] 806. Report status information to the management device of the first network, where the status information is used to indicate the usage status of each network sub-slice in the first network, and the status information is used to monitor each network sub-slice in the first network.

[0187] The device of the first network can determine the usage status of each network sub-slice in the first network in real time according to the session establishment process, or can determine the usage status of each network sub-slice in the first network according to a preset time interval, which is not limited in the embodiment of the present application. After each determination of the usage status, the status information can be reported to the management device of the first network.

[0188] The session establishment process is a service interaction process. As long as there is service interaction, there will be a session establishment process. Therefore, the usage status of each network sub-slice can be determined based on the session establishment process.

[0189] The device of the first network can also determine the usage status of each network sub-slice in the second network in real time according to the session establishment process, or can determine the usage status of each network sub-slice in the second network at a preset time interval. At this time, the status information is also used to indicate the usage status of each network sub-slice in the second network, and the status information is also used to monitor each network sub-slice in the second network.

[0192] 902. Send a first message to a management device of the second network. The first message is used to determine configuration information of the first network sub-slice, and to send the configuration information of the first network sub-slice to a device of the second network, where the configuration information of the first network sub-slice is used to configure the first network sub-slice.

[0265] The following Figure 1The communication network shown in the figure is used as an example to illustrate the process of the network slice management method. Fig.11 , Fig.11 A flowchart of a network slice management method provided for an embodiment of the present application. The management device of the access network, the management device of the bearer network, and the management device of the core network maintain the mapping relationship between status information and resource parameters, and the status information is refined to all devices in the communication network. The campus application service in the campus Internet technology (IT) network accesses the core network device UPF through the standard protocol N6 port.

[0266] Assume that the network slice 1 corresponding to the mobile phone group has been configured in the communication network. As shown in (1), the mobile phone application accesses base station 1, and network slice 1 is online. The SIM card of the camera application is activated on the core network device to open network slice 2. After the camera is turned on, the camera application goes online. As shown in (2), the camera application accesses base station 1, and the registration signaling process of the camera application carries the slice information of network slice 2.

[0267] As shown in (3), base station 1 senses that network slice 2 has not been configured in the access network and the bearer network, and reports it to the management device of the access network. As shown in (4), the core network device senses that network slice 2 has not been configured in the core network and the bearer network, and reports it to the management device of the core network. As shown in (5), the management device of the access network sends instruction information to the management device of the bearer network, and the instruction information indicates that network slice 2 has not been configured in the bearer network. As shown in (6), the management device of the core network sends instruction information to the management device of the bearer network, and the instruction information indicates that network slice 2 has not been configured in the bearer network.

[0268] Fig.11 When the network slice 2 is not configured in the bearer network, the management device of the access network and the management device of the core network will notify the management device of the bearer network. Optionally, only the management device of the access network or the management device of the core network may notify the management device of the bearer network, which is not limited in the embodiments of the present application.

[0269] As shown in (7), the management device of the access network sends configuration information to the access network device. As shown in (8), the management device of the bearer network sends configuration information to the bearer network device. As shown in (9), the management device of the core network sends configuration information to the core network device.

[0270] As shown in (10), the access network device determines the usage status of each network sub-slice in the access network and the bearer network through the 3GPP signaling process, and reports it to the management device of the access network. As shown in (11), the core network device determines the usage status of each network sub-slice in the core network and the bearer network through the 3GPP signaling process, and reports it to the management device of the core network.

[0271] If the management device of the access network determines that there is a network sub-slice in the access network that meets the deletion condition or does not meet the service demand, then as shown in (7), the deletion information or maintenance information is sent to the access network device. If the management device of the core network determines that there is a network sub-slice in the core network that meets the deletion condition or does not meet the service demand, then as shown in (9), the deletion information or maintenance information is sent to the core network device.

[0272] If the management device of the access network determines that there is a network sub-slice in the bearer network that meets the deletion condition or does not meet the service demand, then as shown in (12), a command message is sent to the management device of the bearer network, and the command message indicates that a certain network sub-slice in the bearer network meets the deletion condition or does not meet the service demand. If the management device of the core network determines that there is a network sub-slice in the bearer network that meets the deletion condition or does not meet the service demand, then as shown in (13), a command message is sent to the management device of the bearer network, and the command message indicates that a certain network sub-slice in the bearer network meets the deletion condition or does not meet the service demand. As shown in (8), the management device of the bearer network sends deletion information or maintenance information to the bearer network device.

[0273] Fig.11 The management device of the access network and the management device of the core network will monitor the usage status of the network sub-slice in the bearer network. Optionally, the usage status of the network sub-slice in the bearer network can be monitored only by the management device of the access network or the management device of the core network, which is not limited in this embodiment of the present application.

[0274] Errors may occur when configuring network sub-slices. As shown in (14), when the access network device is unable to configure the network sub-slice due to the physical or logical resources of the access network, it reports the slice configuration failure information to the management device of the access network. As shown in (15), when the bearer network device is unable to configure the network sub-slice due to the physical or logical resources of the bearer network, it reports the slice configuration failure information to the management device of the bearer network. As shown in (16), when the core network device is unable to configure the network sub-slice due to the physical or logical resources of the core network, it reports the slice configuration failure information to the management device of the core network. As shown in (17), (18) and (19), the management device that receives the slice configuration failure information issues an alarm through the user interface of the network management device client, indicating that the manual network slice configuration has failed and manual intervention is required.

[0275] As shown in (17), (18) and (19), when an error occurs in the process of a management device of a network sending a configuration message, a deletion message or a maintenance message to its southbound network element, the management device can issue an alarm through the user interface of the network management device client, indicating that the manual configuration message, deletion message or maintenance message has failed to be sent, and the reason for the failure to send the message, such as "IP address does not exist".

[0276] The following Figure 2 The communication network shown in the figure is used as an example to illustrate the process of the network slice management method. Fig.12 , Fig.12 A flowchart of another network slice management method provided in an embodiment of the present application. The system platform maintains a mapping relationship between status information and resource parameters, and the status information is refined to all devices in the communication network.

[0277] Fig.12 The process (1) to (4) and Fig.11 The processes (1) to (4) are the same, and the embodiments of the present application are not repeated here. After process (3), as shown in (5), the management device of the access network sends instruction information to the system platform, and the instruction information indicates that the network slice 2 has not been fully configured in the bearer network. After process (4), as shown in (6), the management device of the core network sends instruction information to the system platform, and the instruction information indicates that the network slice 2 has not been fully configured in the bearer network. As shown in (7), the system platform sends instruction information to the management device of the bearer network.

[0278] Fig.12 When the network slice 2 is not configured in the bearer network, the management device of the access network and the management device of the core network will notify the system platform. Optionally, only the management device of the access network or the management device of the core network may notify the system platform, which is not limited in the embodiment of the present application.

[0279] Fig.12 The processes (8) to (12) are respectively Fig.11The processes (7) to (11) are the same, and the embodiments of the present application are not repeated here. If the management device of the access network determines that there is a network sub-slice in the bearer network that meets the deletion conditions or does not meet the business requirements, then as shown in (13), a command message is sent to the system platform, and the command message indicates that a certain network sub-slice in the bearer network meets the deletion conditions or does not meet the business requirements. If the management device of the core network determines that there is a network sub-slice in the bearer network that meets the deletion conditions or does not meet the business requirements, then as shown in (14), a command message is sent to the system platform, and the command message indicates that a certain network sub-slice in the bearer network meets the deletion conditions or does not meet the business requirements. As shown in (15), the system platform sends command information to the management device of the bearer network. As shown in (9), the management device of the bearer network sends deletion information or maintenance information to the bearer network device.

[0280] Fig.12 The management device of the access network and the management device of the core network will monitor the usage status of the network sub-slice in the bearer network. Optionally, the usage status of the network sub-slice in the bearer network can be monitored only by the management device of the access network or the management device of the core network, which is not limited in this embodiment of the present application.

[0281] Fig.12 The processes (16) to (21) are respectively Fig.11 The processes (14) to (19) are the same and will not be described in detail in this embodiment of the present application.

[0282] Depend on Fig.11 and Fig.12 It can be seen that under the geographical location coverage of different base stations, different terminal groups will be accessed under different bearer network subnets. There are fixed terminal devices (such as cameras) and mobile terminal devices (such as mobile phones) in the terminal group.
