Detailed ways

In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

A network slice is a logical network that can provide specific network functions and meet specific service requirements, including a collection of network function modules and resources required to complete specific functions or services. An operator may provide multiple network slices that can implement the same network function for groups of terminal devices with different characteristics or quality of service (QoS) levels. The same terminal device can also access multiple network slices at the same time through the 5G access network, and use different types of services provided by these network slices. For example, enhanced mobile broadband (eMBB), ultra-reliable low latency communications (URLLC), and massive Internet of Things (MIoT) can be targeted. Types of services create network slices respectively, and each network slice provides services that can meet the quality of service required by its corresponding service type.

A network slice can be divided into several network slice subnets. A network slice subnet does not need to provide end-to-end complete network services. A network slice subnet can be a collection of network functions of the same device vendor in a network slice, or a collection of network functions divided by domains, such as the core network. A network slice subnet, an access network network slice subnet, or a set formed by other means such as deployment location. A network slice subnet may be shared by multiple network slices.

Network slices and network slice subnets are created and managed by the network slice management system. A network slice management system can create multiple network slices and multiple network slice subnets, and manage them at the same time, such as monitoring the network performance of network slices during operation, managing faults, and modifying configuration parameters.

FIG. 2 exemplarily shows a schematic diagram of a network slice management system. As shown in the figure, a network slice management system (NSMS) may include: a communication service management function (CSMF), Network slice management function (NSMF) and network slice subnet management function (NSSMF).

Among them, CSMF is mainly used to convert communication service-related requirements into network slicing-related requirements, such as network type, capacity, QoS requirements, etc., and send related service requirements and management requests to NSMF through the interface with NSMF.

NSMF is mainly used to receive network slice management requirements related to communication services through the interface with CSMF, manage the life cycle, performance, faults, etc. of network slices, and can further convert related service requirements into network slice subnet-related management requirements , which sends network slice subnet management requirements through the interface with NSSMF.

NSSMF is mainly used to receive network slicing subnet management requirements through the interface with NSMF, and manage the life cycle, performance, and faults of network slicing subnets.

The life cycle management of network slices by the network slice management system can include three stages as shown in Figure 3:

Network slice instantiation, configuration, and activation phase: Create and configure all shared and non-shared network resources and network functions related to the network slice, so that the network slice can run the supported communication services normally during the activation phase.

Network slicing operation stage: monitoring, reporting, and online modification of network slicing performance. Among them, modification operations include online upgrade, reconfiguration, network slice expansion, capacity modification, topology modification, associating and disassociating network functions, and the like.

Network slice decommissioning phase: deactivate the network slice, configure the shared resources or network functions in the network slice, and then terminate the network slice.

As shown in Figure 1, each network element in a network slice establishes a connection through a transmission network. The transmission network establishes communication links based on the addresses of network elements in the network, and supports information transmission between network elements. The transmission network can be based on transmission control protocol/internet protocol (transmission control protocol/internet protocol, TCP/IP) for transmission; network transmission equipment, such as switches, routers, can be based on media access control (media access control, MAC) address, IP Address or TCP port to achieve addressing, transmission.

Different network slices may have different transmission requirements between network elements, and the transmission requirements between different network elements in the same network slice may also be different. Different network slice subnets in a network slice may also have different transmission requirements between network elements. not exactly. For example, a network slice that provides URLLC type services requires a transmission delay of no more than 0.5 ms, while a network slice that provides other types of services requires a lower transmission delay. Therefore, a transport network management system (transport network management system, TNMS) should manage the transport network according to the transmission requirements of the network slicing, so as to meet the requirements of the network slicing. However, at present, the communication interface between the network slice management system and the transmission network management system is not standardized.

The embodiment of the present application provides a network slice management method, which is used to solve the problem of how to communicate between a network slice management device and a transmission network management device.

In the embodiment of the present application, the network slice management device may be NSMF or NSSMF in the network slice management system; however, FIG. 2 is only an example of the network slice management system, so the network slice management device in the embodiment of the present application may also be It is another device that has the function of managing network slices, such as a network manager (network manager, NM), a domain manager (domain manager, DM), or a network element manager (element manager, EM).

The transmission network management device in the embodiment of the present application has a device that manages the transmission network, which is not specifically limited in the present application.

Referring to FIG. 4, which is a schematic flowchart of a network slice management method provided by an embodiment of the present application, as shown in the figure, the method may include the following steps:

Step 401: The network slice management device determines the transmission requirement for the transmission network.

The transmission requirements determined by the network slice management device may be transmission requirements at the network slice level, transmission requirements at the network slice subnet level, or transmission requirements at the connection point pair level in the network slice.

In some embodiments, the network slice management device may determine the transmission requirements of the network slice on the transmission network. Correspondingly, the network slice management device may determine the network slice level transmission requirement for the network slice. If the network slice includes several network slice subnets, the network slice management device can also determine the subnet-level transmission requirements of the network slice, and the network slice subnet-level transmission requirements reflect the network slice's effect on the transmission network. transmission needs. In addition, since the network slice includes several connection point pairs, the network slice management device can also determine the transmission requirements at the connection point pair level for each connection point pair of the network slice.

In other embodiments, the network slice management device may determine the transmission requirements of the network slice subnet to the transmission network. If the network slice subnet includes several nested network slice subnets, the network slice management device may determine the network slice subnet level transmission requirements for the network slice subnet. If the network slice subnet includes several connection point pairs, the network slice management device can also determine the transmission requirements of the connection point pair level of the network slice subnet for each connection point pair, and then reflect the network slice subnet transmission needs.

In still other embodiments, the network slice management device may also determine the transmission requirements of the connection point on the transmission network. For example, in order to improve the performance of a network slice or subnet, the network slice management device may determine to create a new connection point pair for a network slice or subnet, and determine the connection point pair level corresponding to the connection point pair to be created. transmission needs.

In a possible implementation manner, the transmission requirements of various levels determined by the network slice management device may include a first transmission performance requirement, or may include a first transmission performance requirement and a second transmission performance requirement.

The first transmission performance requirement indicates that the transmission network needs to create, modify or release transmission resources of a corresponding level. For example, the network slice management device may determine the transmission resources for creating the network slice, or determine that the transmission resources of the created network slice need to be modified, or may also determine to release the transmission resources of the network slice. Of course, the network slice management device can determine the transmission requirements that need to be created, modified or released for the network slice subnet, or can also determine the need to create, modify or release the transmission resources of the connection point pair.

The second transmission performance requirement is a transmission performance requirement parameter of a corresponding level to be created or to be modified. In some scenarios, the first transmission performance requirement determined by the network slice management device is that a network slice needs to be created, and further determines the slice level or subnet level or connection point pair level transmission performance parameters that need to be met by the network slice to be created, For example, total bandwidth parameters at the slice level, unified delay parameters, total throughput rate, slice level priority, isolation requirements, etc. In some other scenarios, the first transmission performance requirement determined by the network slice management device is to modify the transmission performance requirement of the created network slice, and further determine the transmission performance parameters that the network slice to be modified needs to meet after modification. In some other scenarios, the network slice management device can also determine the transmission requirements that need to create or modify network slice subnets or connection point pairs according to actual requirements. Correspondingly, the second transmission performance requirement represents the created or modified transmission requirements. Transport performance parameters at the network slice subnet level or connection point pair level.

In some embodiments, the first transmission performance requirement determined by the network slice management device may also be a requirement for releasing network slices, network slice subnets, or connection point pairs. In this case, the network slice management device may no longer determine the second transmission performance. performance requirements.

In a possible implementation manner, the network slice management device determines the network slice level transmission requirements, which may also include the first transmission performance requirements, or include the first transmission performance requirements and the second transmission performance requirements. The first transmission performance requirement may be a transmission resource for creating, modifying or releasing a network slice, and the second transmission performance requirement may be a slice-level transmission performance requirement parameter of the network slice to be created or modified. The slice-level performance requirement parameter refers to the value range or level of the sum of the transmission performance requirements of all connection point pairs in the slice, or the uniform value range or level of the performance requirement parameter of all connection point pairs. For example, as shown in Figure 7, the network slice includes k connection point pairs, the network slice management device can determine that the total bandwidth of the k connection point pairs is X megabytes, and the transmission delay parameters of the k connection point pairs are unified The maximum value is Y milliseconds. Correspondingly, the transmission network configures X megabytes of bandwidth for the k connection point pairs, and configures a unified maximum transmission delay of Y milliseconds for each connection point pair. Optionally, the transmission network can dynamically adjust the bandwidth of each connection point pair while ensuring that the total bandwidth of the k connection point pairs is X megabytes. Although the network slice includes k connection point pairs, it does not mean that the network slice includes 2*k network elements. For example, connection point pair 1 and connection point pair 2 in Figure 5 both include network element gNB1, or two Uplink and downlink between network elements may also become two connection point pairs.

Optionally, the network slice-level transmission requirement determined by the network slice management device may further include the topology requirement of the network slice. In a specific embodiment, if the network slice management device determines to create or modify a network slice, the network slice management device may further determine the connection relationship to be established or to be modified between the network elements in the network slice. For example, the network slice management device requests to create a network slice, the network slice includes network element 1, network element 2 and network element 3, the network slice management device can also determine that network element 1 and network element 2 need to establish a connection point pair, Network element 1 and network element 3 need to establish a connection point pair.

In another possible implementation manner, when the network slice management device determines the transmission requirement at the network slice level, it may first determine the transmission requirement within the network slice subnet in the network slice and/or between the network slice subnets The transmission requirements of the network slice are further determined at the slice level of the network slice. Because there are various ways of dividing network slice subnets in network slicing, the network elements in the divided network slice subnet may need to communicate, or the network elements in the network slice subnet may not need to communicate, only Communication between network slice subnets, so when the network slice management device determines the transmission requirements at the network slice level, it can determine the network slice level after comprehensively considering the transmission requirements within the network slice subnets or between network slice subnets. transmission needs.

For example, taking Figure 6 as an example, the newly created network slice utilizes the created network slice subnet A, network slice subnet B, and network slice subnet C, where network slice subnet A includes gNB1 and gNB2, and network slice subnet A includes gNB1 and gNB2. Subnet B includes AMF, and network slice subnet C includes UPF. The network slice management device can first determine the transmission requirements between network slice subnet A and network slice subnet B, the transmission requirements between network slice subnet A and network slice subnet C, and the network slice subnet B and network slice subnet B. The transmission requirements between the network Cs are determined, and the transmission requirements at the slice level of the network slice are determined according to the transmission requirements between these subnets. Specifically, the network slice management device obtains a total of 5 connection point pairs between network slice subnet A, network slice subnet B, and network slice subnet C, namely gNB1 and AMF, gNB1 and UPF, gNB2 and AMF, and gNB2 and UPF, AMF and UPF. The network slice management device may determine the transmission requirements at the network slice level according to the acquired information of the connection point pairs and/or the transmission requirements of each connection point pair.

In another possible implementation, when the network slice management device determines the network slice-level transmission requirements for the network slice, it can determine the network slice-level transmission requirement parameters corresponding to the network slice according to the service requirements supported by the network slice. value range or level. For example, if a network slice is used to provide URLLC type services, the network slice management device can determine the unified throughput rate of the network slice level corresponding to the network slice according to the requirements of high reliability and low latency of URLLC type services , the value range or level of parameters such as unified transmission delay.

Of course, the network slice management device can also determine the network slice level corresponding to the network slice by combining the service requirements supported by the network slice, the transmission requirements of the connection point pairs in the network slice, and the transmission requirements between network slice subnets. transmission needs.

In a possible implementation manner, the transmission requirement at the network slice subnet level may include the identifiers of the first network slice subnet and the second network slice subnet. Optionally, the transmission requirement at the network slice subnet level may also Including the identifiers of the network slices to which the first network slice subnet and the second network slice subnet belong. Optionally, the transmission requirements at the network slice subnet level may further include transmission requirements during communication between the first network slice subnet and the second network slice subnet. The subnet-level transmission requirements of the first network slice subnet and the second network slice subnet determined by the network slice management device may further include the first transmission performance requirement, or the first transmission performance requirement and the second transmission performance requirement. The first transmission performance requirement may be creating, modifying or releasing transmission resources between the first network slice subnet and the second network slice subnet, and the second transmission performance requirement may be the network slice sub-network to be created or modified Subnet-level transmission performance requirement parameters between networks. The subnet-level transmission performance requirement parameter refers to the value range or level of the sum of the transmission performance requirements of all connection point pairs between the first network slice subnet and the second network slice subnet, or the first network slice subnet A uniform value range or level of the performance requirement parameter of all connection point pairs between the second network slice subnet and the second network slice subnet.

Optionally, the network slice subnet-level transmission requirement determined by the network slice management device may further include topology information between the two network slice subnets. The topology information includes the information of the network elements in the first network slice subnet to be connected and the network elements in the second network slice subnet, the connection relationship to be established between the network elements and the information of the network elements in the second network slice subnet. The identifier of the pair of connection points formed after the connection. For example, the network slice management device may determine the connection relationship between the network element 1 in the network slice subnet 1 and the network element 2 in the network slice subnet 2.

Specifically, when determining the subnet-level transmission requirements between the first network slice subnet and the second network slice subnet, the network slice management device may first determine the external transmission requirements of the first network slice subnet and the first network slice subnet respectively. 2. The external transmission requirements of the network slicing subnet, and then according to the external transmission requirements of the first network slicing subnet and the external transmission requirements of the second network slicing subnet, determine the relationship between the first network slicing subnet and the second network slicing subnet The transmission requirements for communication between them.

The external transmission requirement of the first network slice subnet is a transmission requirement when the network elements in the first network slice subnet and network elements other than the first network slice subnet perform transmission. For example, as shown in Figure 5, the network slice subnet A includes gNB1 and gNB2, and gNB1 can be connected to the AMF through the transmission network, and can also be connected to the UPF through the transmission network. The network slice management device can respectively determine the transmission requirements of the transmission network when gNB1 in the network slice subnet A communicates with the network elements such as AMF, the transmission requirements of the transmission network when gNB1 communicates with the network elements such as UPF, and gNB2 The transmission requirements for the transmission network when communicating with network elements such as AMF and the transmission requirements for the transmission network when gNB2 communicates with network elements such as UPF.

Similarly, the external transmission requirement of the second network slice subnet is the transmission requirement when the network elements in the second network slice subnet and the network elements other than the second network slice subnet perform transmission. As shown in Figure 5, the network slice subnet B includes AMF1 and UPF1, AMF1 can be connected to the gNB through the transmission network, and UPF1 can be connected to the gNB through the transmission network. The network slice management device can respectively determine the transmission requirements for the transmission network when the AMF1 in the network slice subnet B communicates with the network elements such as gNB and the transmission requirements for the transmission network when the UPF1 communicates with the network elements such as the gNB.

After determining the external transmission requirements of the first network slice subnet and the second network slice subnet respectively, the network slice management device further determines the transmission requirements between the first network slice subnet and the second network slice subnet. Still taking Figure 5 as an example, the network slice subnet A and the network slice subnet B may include a connection point pair 1 formed by gNB1 and AMF1, a connection point pair 2 formed by gNB1 and UPF1, and a connection point pair formed by gNB2 and AMF1. 3. Connection point pair 4 formed by gNB2 and UPF1. If the demand for bandwidth when gNB1 communicates with AMF is 20M, the demand for bandwidth when gNB2 communicates with AMF is 10M, and the demand for bandwidth when AMF1 communicates with gNB is 10M, then determine the connection point pair 1 (gNB1 and AMF1 ) The demand for bandwidth is 20M, and the demand for bandwidth for connection point pair 3 (gNB2 and AMF1) is 10M; if the demand for bandwidth when gNB1 communicates with UPF is 10M, the demand for bandwidth when gNB2 communicates with UPF is 5M, and When UPF1 communicates with gNB, the bandwidth requirement is 5M, so it is determined that the bandwidth requirement of connection point pair 2 (gNB1 and UPF1) is 10M, and the bandwidth requirement of connection point pair 4 (gNB2 and UPF1) is 5M. Then the bandwidth requirement at the subnet level between the network slice subnet A and the network slice subnet B is (20+10+10+5)M.

In some embodiments, when the network slice management device determines the transmission requirements at the subnet level for the network slice, it may determine the transmission requirements at the subnet level between the subnets in the network slice according to the service requirements supported by the network slice. The value range or level of the parameter. For example, as shown in Figure 6, network slice subnet A includes gNB1 and gNB2, network slice subnet B includes AMF, and network slice subnet C includes UPF. Control plane information is transmitted, while user plane information is transmitted between network slice subnet A and network slice subnet C. Therefore, the subnet-level transmission requirements between network slice subnet A and network slice subnet B It can be determined according to the transmission requirements of the control plane information in the service requirements. For example, the delay is X milliseconds, and the transmission requirements at the subnet level between the network slice subnet A and the network slice subnet C can be determined according to the service requirements. It is determined according to the transmission requirements of the plane information, such as the delay of Y milliseconds. You can also set the priority of transmission between network slice subnet A and network slice subnet B to high priority, and set the priority of transmission between network slice subnet A and network slice subnet C to low priority. Level, when gNB1 and gNB2 need to communicate with the AMF in the network slice subnet B and the UPF in the network slice subnet C at the same time, if the transmission resources cannot meet the information to be sent at the same time, they will give priority to the network slice subnet B. The AMF sends the information, and then sends the information to the UPF in the network slice subnet C.

Specifically, two network elements capable of establishing a connection for communication may form a connection point pair, and the transmission requirement of the connection point pair is the transmission requirement between the two network elements. In order to accurately realize the service requirements of network slicing, the network slice management device can determine the transmission requirements of the connection point pair level corresponding to one or some connection point pairs, so that the transmission network can adjust the corresponding transmission requirements according to the transmission requirements of the connection point pair level. The connection point configures the transmission resources between the two included network elements to meet their corresponding transmission requirements.

In a specific embodiment, different priority levels may be set for different connection point pairs. For example, since the priority of the control plane information is higher and the priority of the user plane information is lower, the next generation node (gNB) can be connected with the access and mobility management function (AMF) ), the priority of the connection point pair formed by ) is set to a high priority level, and the priority of the connection point pair formed by the gNB and the user plane function (UPF) is set to a low priority level; When the communication needs are carried out, if the transmission resources cannot satisfy the simultaneous transmission of information, the information is sent to the AMF first, and then to the UPF.

In another specific embodiment, the priority at the data packet level can also be set for different types of data packets in the same connection point pair. For example, the data packets transmitted between the network element AMF and the gNB may contain various types for managing the registration, mobility, and session establishment of the terminal, and each type of data packet may have different transmission requirements due to different service requirements. , so when the AMF sends different types of data packets to the gNB at the same time and the transmission resources are limited, the data packets with higher transmission requirements can be preferentially transmitted.

Similar to the above-mentioned setting of different priorities for different connection point pairs, different second transmission performance requirements such as delay and bandwidth may also be set for different connection point pairs, which will not be repeated here.

In addition, since a connection point pair can be shared by multiple network slices, when the connection point pair transmits information in different network slices, the transmission network can transmit the information according to the transmission requirements of the network slice corresponding to the information. For example, connection point pair 1 is shared by network slice A and network slice B. The network slice management device determines that the delay of connection point pair 1 when transmitting the information in network slice A is 0.5ms, while the connection point pair is transmitting network slice A with a delay of 0.5ms. The delay when the information in B is 1ms, then the transmission network should control the delay within 0.5ms when transmitting the information in network slice A, and should control the delay within 1ms when transmitting the information in network slice B Inside.

In a specific embodiment, network slice A includes network element 1 and network element 2. When network slice A is created, network element 1 and network element 2 have been established, forming connection point pair 1; and when network slice B is subsequently created , network slice B also includes network element 1 and network element 2, and network element 1 and network element 2 in network slice B also need to establish a connection. The transmission network establishes a logical link between network element 1 and network element 2 for network slice A and network slice B respectively. Optionally, the transmission network may establish only one physical link between network element 1 and network element 2, or may also establish one physical link for network slice A and network slice B respectively.

In some embodiments, for the connection point pair formed by two network elements, the uplink and the downlink may be further distinguished, and the uplink and the downlink are respectively regarded as two connection point pairs. For example, the information sent by network element 1 to network element 2 is called uplink, and the uplink corresponds to connection point pair 1; the information sent by network element 2 to network element 1 is called downlink, and the downlink corresponds to connection point pair 2. In some application scenarios, the uplink and downlink transmission requirements may also be different. Therefore, if the uplink or downlink transmission requirements can be further determined and notified to the transmission network when determining the transmission requirements of the connection point pair level, the transmission network can be more accurate. It can perform uplink and downlink transmission to further meet user needs and improve user experience.

As mentioned above, due to the transmission requirement of the connection point pair level determined by the network slice management device, it may be the transmission requirement of the connection point pair formed by two network elements, or the connection point pair formed by the same two network elements. The transmission requirements in different network slices or network slice subnets can also be the same as the uplink or downlink transmission requirements between two network elements. Therefore, the identification of the connection pair determined by the network slice management device can only distinguish which two The connection point pair formed by network elements can also be able to distinguish the connection point pair formed by the same two network elements in different network slices or network slice subnets, and can also distinguish the uplink or downlink between the same two network elements. road.

For example, the connection point pair identifier 1 may only indicate the connection point pair formed by network element 1 and network element 2, but cannot distinguish whether the connection point pair is in network slice 1 or network slice 2. If the network slice management device wants to further To distinguish, the connection point pair identification 1 + the identification of the network slice 1, or the connection point pair identification 1 + the identification of the network slice 2 may be used to distinguish. For another example, the connection point pair identifier A may represent the connection point pair of network element 1 and network element 2 in network slice 1, and the connection point pair identifier B may represent the connection point pair of network element 1 and network element 2 in network slice 2. . For another example, the connection point pair identifier I represents the transmission link when the network element 1 sends information to the network element 2, and the connection point pair identifier II represents the transmission link when the network element 2 sends information to the network element 1.

In a possible implementation manner, the transmission requirements within the network slice subnet may include transmission requirements at the network slice subnet level and/or transmission requirements at the connection point pair level. Specifically, the transmission requirement within the network slice subnet is the transmission requirement for communication between network elements in a network slice subnet.

Optionally, the transmission requirements within the network slice subnet determined by the network slice management device may also include topology requirements within the network slice subnet. In a specific embodiment, if the network slice management device determines to create or modify a network slice subnet, the network slice management device may further determine the connection relationship to be established or to be modified between network elements in the network slice subnet.

Further, the transmission requirements within the network slice subnet determined by the network slice management device may further include a first transmission performance requirement, or may include a first transmission performance requirement and a second transmission performance requirement. The first transmission performance requirement may be the creation, modification or release of transmission resources within the network slice subnet, and the second transmission performance requirement may be the subnet level and/or connection within the network slice subnet to be created or modified Point-to-point transmission performance requirements parameters.

In a specific embodiment, when the network slice management device determines the transmission requirements inside the network slice subnet for the network slice subnet, it can determine the network slice level corresponding to the network slice according to the service requirements supported by the network slice subnet and/or connection point-to-level transport requirements. For example, if a network slice subnet is used to provide terminal access services, the network slice management device can determine the transmission requirements within the network slice subnet according to the access service requirements; if a network slice subnet is used to provide core network function, the network slice management device can determine the transmission requirements within the network slice subnet according to the requirements of the core network function.

In another specific embodiment, when the network slice management device determines the transmission requirements inside the network slice subnet for the network slice subnet, it can summarize the transmission requirements of the connection point pairs formed by each network element in the network slice subnet to obtain Transport requirements within this network slice subnet. For example, a network slice subnet includes gNB1, gNB2 and AMF, gNB1 and AMF can establish a connection to form connection point 1, and gNB2 and AMF can establish a connection to form connection point 2, then the transmission requirements of connection point 1 and The transmission demand of the connection point pair 2 is used as the transmission demand within the subnet of the network slice. If the bandwidth requirements of connection point 1 and connection point 2 are both 10M, it can be considered that the bandwidth demand inside the network slice subnet is 20M; if the bandwidth requirements of connection point 1 and connection point 2 are both 1ms , it can be considered that the delay requirement inside the network slice subnet is 1ms.

In addition, the network slice management device can also determine the transmission requirements inside the network slice subnet according to the service requirements supported by the network slice subnet and the transmission requirements of each connection point pair in the network slice subnet.

In a specific embodiment, the external transmission requirements of each network slice subnet in the network slice or the transmission requirements of network elements may be determined by the NSSMF, and the NSSMF sends the determined external transmission requirements of the network slice subnets to the NSMF. The received external transmission requirements of each network slice subnet are integrated, and the transmission requirements at the network slice level or the subnet level or the connection point level are determined. NSMF sends the determined transmission requirements of the network slice to the transmission network management. equipment. Of course, the above NSMF can also be replaced by other network slice management devices.

Step 402: The network slice management device sends a network slice transmission management request to the transmission network management device, where the request includes the above-mentioned transmission requirement information.

As mentioned above, the network slice management device has determined the transmission requirements at the network slice level, network slice subnet level or connection point pair level, and then carries the determined transmission requirement information in the network slice transmission management request and sends it to the network slice transmission management request. network management equipment.

In a possible implementation manner, the information of the transmission requirement at the network slice level includes the identifier of the network slice, that is, the identifier of the network slice to be created, to be modified or to be released determined by the network slice management device. The identifier of the network slice may be the identification (identification, ID) of the network slice, or may also be other identifiers that can be used to distinguish each network slice. For example, if the network slice management device does not want to expose the ID of the network slice to Transport network, other mapping identifiers can be used.

Further, the information of the transmission requirement at the network slice level may further include at least one of topology information and transmission performance requirement information of the network slice corresponding to the above-mentioned network slice identifier.

As mentioned above, the transmission requirement of the network slice may include the first transmission performance requirement, or the first transmission performance requirement and the second transmission performance requirement, and correspondingly, the transmission performance information may also include the first transmission performance requirement information, or the first transmission performance requirement. Transmission performance requirement information and second transmission performance requirement information.

Specifically, the first transmission performance requirement information indicates that the network slice management request is used to instruct the transmission network management device to create, modify or release the transmission resources of the network slice corresponding to the network slice identifier. For example, the first transmission performance requirement information can be used with Two bits indicate that when the value of these two bits is "00", it can indicate creation, "01" can indicate modification, and "10" can indicate release.

The second transmission performance requirement information corresponds to the aforementioned second transmission performance requirement, and the network slice management device sends the determined transmission performance requirement to the transmission network management device through the second transmission performance requirement information. As mentioned above, the second transmission performance requirement information may include parameters such as priority, bandwidth, delay, throughput, isolation, and the like.

Specifically, each transmission performance requirement parameter can be used to indicate the value or level of the sum of the transmission performance requirements of each connection point pair to be created or modified in the network slice. For example, if the bandwidth parameter is 100M, it can indicate that the The sum of the bandwidth of each connection point pair is 100M, but the transmission network can dynamically adjust the bandwidth of each connection point pair; or, it can also be used to indicate the uniform value of the transmission performance requirement parameter of each connection point pair in the network slice The range or level, for example, the delay parameter may indicate the unified maximum delay or delay level of each connection point, and the priority parameter may indicate the level of the priority of each connection point to transmit information. The meaning of each transmission performance requirement parameter may be pre-agreed, so that the transmission network management device can correctly create or modify the transmission resources of the network slice according to each parameter.

The topology information of the network slice corresponds to the aforementioned topology requirements, and may include information of network elements to be connected in the network slice, connection relationships between network elements to be established, and identifiers of connection point pairs formed after the connection is established.

For example, when the network slice management device requests to create a network slice, the transmission network needs to establish the connection between network element 1 and network element 2 and the connection between network element 1 and network element 3 in the network slice to be created. At this time, the network slice management device can send the information of network element 1, the information of network element 2, the indication information of the connection between network element 1 and network element 2, and the identification of the connection point pair formed by network element 1 and network element 2 to the transmission. network management equipment; it can also send the information of network element 1, the information of network element 3, the indication information that network element 1 and network element 3 establish a connection relationship, and the identification of the connection point pair formed by network element 1 and network element 3 to the transmission network management equipment.

Optionally, the information of the network element may include the name, ID, IP address, MAC address, port number information, ID of the virtual local area network (virtual local area network, VLAN) of the network element, etc., for identifying the network element to be connected to. .

As mentioned above, the identification of the connection point pair can be used to distinguish the connection point pair formed between different network elements. Further, the identifier of the connection point pair can also be used to distinguish the connection point pair formed by the same two network elements in different network slices. In addition, the connection point pair identifier can also be used to distinguish the uplink and downlink transmission links between the two network elements.

In a possible implementation manner, the information on transmission requirements at the network slice subnet level may include information on transmission requirements between network slice subnets.

Specifically, the information of transmission requirements between network slice subnets includes the identifier of the first network slice subnet and the identifier of the second network slice subnet, that is, the identifiers to be created, to be modified or to be determined by the network slice management device. Release transmission resources between the first network slice subnet and the second network slice subnet. The identifier of the network slice subnet may be the ID of the network slice subnet, or may also be other identifiers that can be used to distinguish each network slice subnet.

Further, the information on the transmission requirements between the network slice subnets may also include topology information between the first network slice subnet and the second network slice subnet and the relationship between the first network slice subnet and the second network slice subnet. At least one of the transmission performance requirement information between them.

As mentioned above, the transmission performance information between the network slice subnets may also include the first transmission performance requirement information, or the first transmission performance requirement information and the second transmission performance requirement information. Specifically, the first transmission performance requirement information indicates that the network slice management request is used to instruct the transmission network management device to create, modify or release transmission resources between the first network slice subnet and the second network slice subnet; the second transmission performance The demand information represents the transmission demand performance parameters between network slice subnets. Specifically, each transmission performance requirement parameter can be used to indicate the value range or level of the sum of the transmission performance requirements of each connection point pair to be created or to be modified between two network slice subnets, and can also be used to indicate The uniform value range or level of the transmission performance requirement parameter of each connection point pair between the network slice subnets.

The topology information between the network slice subnets corresponds to the above-mentioned topology requirements between the network slice subnets, and may include the information of the network elements to be established between the two network slice subnets, the network elements to be established between the network elements. The connection relationship and the identification of the connection point pair formed after the connection is established. Specifically, for the information of the network element and the identification of the connection point pair, reference may be made to the above-mentioned topology information at the network slice level.

In a possible implementation manner, the information of the transmission requirement at the connection point pair level in the network slice may include the identifier of the connection point pair, that is, the identifier of the connection point pair to be created, to be modified or to be deleted. Specifically, the identifier of the connection point pair is used to represent the connection relationship between two network elements, so that when the connection pair is subsequently modified or released, the network slice management device can no longer use the information of the network elements in the connection point pair. It is sent to the transmission network management device, and the transmission network management device can know which two network elements to modify or release the transmission resources between by only sending the identification of the connection point pair.

Further, the information of the transmission requirement of the connection point pair may also include at least one of the topology information of the connection point pair corresponding to the above connection point pair identifier and the transmission performance requirement information of the connection point pair level corresponding to the above connection point pair identifier. kind.

As mentioned above, the transmission performance information at the connection point pair level may also include the first transmission performance requirement information, or the first transmission performance requirement information and the second transmission performance requirement information. Specifically, the first transmission performance requirement information indicates that the network slice management request is used to instruct the transmission network management device to create, modify or release the transmission resources of the connection point pair corresponding to the above connection point pair identifier; the second transmission performance requirement information indicates that the connection Peer-to-peer transmission demand performance parameters.

The topology information of the connection point pair may include the information of the network elements in the connection point pair to be established, and the connection relationship to be established between the network elements. Optionally, the information of the network element may include the name, ID, IP address, MAC address, port number information, VLAN ID, etc. of the network element, which are used to identify the network element to be connected.

In a possible implementation manner, the information on the transmission requirement inside the network slice subnet may include information on the transmission requirement at the network slice subnet level or the connection point pair level.

Specifically, the information of the transmission requirement inside the network slice subnet includes the identifier of the network slice subnet, that is, the identifier of the network slice subnet to be created, to be modified or to be released determined by the network slice management device. The identifier of the network slice subnet may be the ID of the network slice subnet, or may also be other identifiers that can be used to distinguish each network slice subnet.
