Specific embodiment
In order to keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with attached drawing to the application make into One step it is described in detail.
Network slice is the logical network that can be provided particular network functions, meet special services demand, includes completing The set of network function module and resource needed for specific function or service.Operator can be different characteristic or service quality The terminal device group of (quality of service, QoS) grade provides the multiple networks slice for being able to achieve identical network function. Same terminal device can also access net by 5G while access multiple networks and be sliced, provided not using these networks slice The service of same type.For example, can for reinforced type mobile broadband service (enhanced mobile broadband, eMBB), High reliability low time delay communicates (ultra-reliable low latency communications, URLLC) and extensive Network slice is respectively created in the service of Internet of Things (massive Internet of Things, MIoT) these three types, each The service of service quality needed for network slice offer can satisfy its corresponding service type.
One network slice can be divided into several network slice subnets.Network slice subnet can not need offer end and arrive The complete network service at end, network slice subnet can be the network function composition collection of the same equipment vendor in network slice It closes, is also possible to the set of the network function divided by domain, such as core net network slice subnet, access net network slice Net, or set is formed by other modes such as deployed positions.Network, which is sliced subnet and may be sliced by multiple networks, to be shared.
Network slice, network slice subnet are by the creation of network slice management system, management.One network is sliced management system Multiple network slices, multiple networks slice subnet can be created, and they are managed simultaneously, such as network slice is being transported Network performance during row monitored, fault management, modification configuration parameter etc..
Fig. 2 illustratively gives a kind of schematic diagram of network slice management system, as shown, network slice management system System (network slice management system, NSMS) may include: communication service management function (communication service management function, CSMF), network are sliced management function (network Slice management function, NSMF) and network slice subnet management function (network slice subnet Management function, NSSMF).
Wherein, CSMF is mainly used for converting the relevant requirement of network slice, such as net for the relevant requirement of communication service Network type, capacity, qos requirement etc., and related service is required and managed request by the interface with NSMF and is sent to NSMF.
NSMF is mainly used for being sliced management requirement by network relevant to the interface communication service of CSMF, to network Life cycle, performance, failure of slice etc. are managed, and can further require related service to be converted into network slice Relevant management requirement is netted, is sliced subnet management demand by sending network with the interface of NSSMF.
NSSMF is mainly used for being sliced subnet to network by being sliced subnet management requirement with the interface network of NSMF Life cycle, performance, failure etc. be managed.
The life cycle management that network slice management system is sliced network may include three phases as shown in Figure 3:
The instantiation of network slice, configuration, activation stage: all shared, non-shared network resources relevant to network slice And network function is created, is configured, and network slice is allowed to operate normally supported every communication in the activation stage Service.
Network is sliced the operation phase: to the supervision of network chip property, report and online modification.Wherein, modification operation packet Online upgrading is included, reconfigured, the dilatation of network slice, capacity modification, topological structure modification, be associated with and conciliate related network function etc..
Network is sliced retirement phase: being sliced to network and carries out de-activated operation, to the shared resource or net in network slice Network function is configured, and network slice is then terminated.
As shown in Figure 1, by transmission network establishing connection between each network element in network slice.Transmission network is based on each in network Communication link is established in the address of network element, supports the information transmission between network element.Transmission network can be based on transmission control protocol/Yin Te Net interconnection protocol (transmission control protocol/internet protocol, TCP/IP) is transmitted；Net Network transmission device, such as interchanger, router, can based on media access control (media access control, MAC) Location, IP address or TCP port realize addressing, transmission.
Heterogeneous networks slice may be different to the transmission demand between network element, and in consolidated network slice to different network elements it Between transmission demand may also be different, in network slice different network slice subnets to the transmission demand between network element also not to the utmost It is identical.For example, it is and to provide other no more than 0.5ms that the network for providing URLLC type of service, which is sliced requirement to propagation delay time, The requirement that the network of type of service is sliced to propagation delay time is then relatively low.Therefore, transmission network management system (transport Network management system, TNMS) transmission network should be managed according to the transmission demand that network is sliced, into And meets the needs of network slice.But network is sliced the communication interface between management system and transmission network management system at present It is not standardized.
The embodiment of the present application provides a kind of network slice management method, to solve network slice management equipment and transmission The problem of how being communicated between net management equipment.
In the embodiment of the present application, network slice management equipment can be network slice management system in NSMF or NSSMF；However, Fig. 2 is only an example of network slice management system, therefore the network in the embodiment of the present application is sliced management Equipment, which is also possible to other, has the equipment for being managed function to network slice, such as network manager (network Manager, NM), domain manager (domain manager, DM) or NE Explorer (element manager, EM).
Transmission network management equipment in the embodiment of the present application has the equipment for being managed function to transmission network, the application couple This is not specifically limited.
Referring to fig. 4, the flow diagram of management method is sliced for network provided by the embodiments of the present application, as shown, should Method may comprise steps of:
Step 401, network slice management equipment determine the transmission demand to transmission network.
Wherein, the transmission demand that network slice management equipment is determined can be the transmission demand of network slice level, It can be sliced the other transmission demand of sub-network level for network, can also be the tie point in network slice to the transmission demand of rank.
In some embodiments, network slice management equipment can determine network slice to the transmission demand of transmission network.Phase Ying Di, network slice management equipment can determine the transmission demand of network slice level for network slice.If the network It include that several networks are sliced subnet in slice, network slice management equipment can also determine that the sub-network level of network slice is other Transmission demand, embodying network slice by several networks slice other transmission demand of sub-network level needs the transmission of transmission network It asks.Further, since including several tie points pair in network slice, network is sliced management equipment can also be for network slice Each tie point is to determining tie point to the transmission demand of rank.
In other embodiments, network slice management equipment can determine transmission of the network slice subnet to transmission network Demand.If the network is sliced the network in subnet including several nestings and is sliced subnet, network slice management equipment can be directed to should Network slice subnet determines that network is sliced the other transmission demand of sub-network level.If it includes several tie points in subnet that the network, which is sliced, It is right, network slice management equipment can also for each tie point to determine the network slice subnet tie point to rank Transmission demand, and then embody the transmission demand of network slice subnet.
In further embodiments, network slice management equipment can also determine that tie point needs the transmission to transmission network It asks.For example, network is sliced management equipment to improve the performance of network slice or subnet, can be determined as network slice or Subnet creates a new tie point pair, and determines that tie point to be created needs corresponding tie point to the transmission of rank It asks.
In one possible implementation, the transmission demand of various ranks that network slice management equipment is determined can be with It including the first transmission performance demand, or may include the first transmission performance demand and the second transmission performance demand.
Wherein, the first transmission performance requirement representation needs the transfer resource of transmission network creation, modification or release appropriate level. For example, network, which is sliced management equipment, can determine the transfer resource of creation network slice, or determine what needs modification had created The transfer resource of network slice, or can also determine the transfer resource for discharging network slice.Certainly, the management of network slice is set It is standby to determine the transmission demand for needing creation, modification or releasing network slice subnet, or can also determine and need to create, repair Change or discharge the transfer resource of tie point pair.
Second transmission performance demand is the transmission performance demand parameter of appropriate level to be created or to be modified.In some fields Jing Zhong, the first transmission performance demand that network slice management equipment is determined are to need to create network slice, and further determine that Network to be created is sliced the slice level for needing to meet or subnet rank or tie point to the transmission performance parameter of rank, such as Total bandwidth parameter of slice level, unified delay parameter, total throughput, slice level priority, isolation requirement etc..Also Have in some scenes, the first transmission performance demand that network slice management equipment is determined is that the network that modification has created is sliced Transmission performance demand, and further determine that network to be modified be sliced it is modified after the transmission performance parameter that needs to meet.? In other scene, network slice management equipment can also be determined to need to create or modify network slice according to actual needs The transmission demand of subnet or tie point pair, correspondingly, the second transmission performance demand then indicate after creating or modified network Subnet rank or tie point are sliced to the transmission performance parameter of rank.
In some embodiments, the first transmission performance demand that network slice management equipment is determined is also likely to be release net The demand of network slice, network slice subnet or tie point pair, network slice management equipment then can no longer determine the second biography at this time Defeated performance requirement.
In one possible implementation, network slice management equipment determines the transmission demand of network slice level, It also may include the first transmission performance demand, or including the first transmission performance demand and the second transmission performance demand.Wherein, The transfer resource that one transmission performance demand can be sliced for creation, modification or releasing network, the second transmission performance demand can be The transmission performance demand parameter of the slice level of network slice after to be created or to be modified.The performance demand parameters of slice level Refer to that the value range of the sum of transmission performance demand of all tie points pair or grade or all tie points need performance in slice Ask the unified value range or grade of parameter.For example, as shown in fig. 7, including k tie point pair, network in network slice Slice management equipment can determine that the bandwidth summation of this k tie point pair is X million, the transmission time delay parameters of this k tie point pair Unified maximum value is Y milliseconds, and correspondingly, it is every tie point pair that transmission network, which is bandwidth of this k tie point to configuration X million, Configuring unified propagation delay time maximum value is Y milliseconds.Optionally, transmission network can be X in the total bandwidth for guaranteeing k tie point pair While million, the bandwidth of every tie point pair is dynamically adjusted.Although including k tie point pair in network slice, it is not meant to Include 2*k network element in network slice, for example, tie point in Fig. 5 to 1 and tie point in 2 comprising network element gNB1, or Uplink and downlink between two network elements may also become two tie points pair.
Optionally, the transmission demand for the network slice level that network slice management equipment is determined, can also include the net The topological demand of network slice.In a specific embodiment, if network slice management equipment determines one network of creation or modification Slice, network slice management equipment may further determine that in network slice between each network element wait establish or connection to be modified Relationship.For example, network slice management equipment request creates a network slice, it include network element 1,2 and of network element in network slice Network element 3, network slice management equipment can also determine that network element 1 and network element 2 need to establish tie point pair, and network element 1 and network element 3 need Establish tie point pair.
In alternatively possible implementation, network is sliced management equipment in the transmission demand for determining network slice level When, it can first determine between transmission demand and/or the network slice subnet inside the network slice subnet in network slice Transmission demand, then further determine that out the network slice slice level transmission demand.Due to being divided in network slice The mode that network is sliced subnet is varied, and therefore, the network element inside network slice subnet marked off may be led to Letter, it is also possible to the network element inside network slice subnet does not need to be communicated, and only carries out the communication between network slice subnet, therefore And network is sliced management equipment when determining the transmission demand of network slice level, can comprehensively consider in network slice subnet After transmission demand between portion or network slice subnet, the transmission demand of network slice level is determined.
For example, the network slice subnet A created, network slice is utilized in newly created network slice by taking Fig. 6 as an example It nets B and network is sliced subnet C, wherein include gNB1 and gNB2 in network slice subnet A, it includes AMF in subnet B that network, which is sliced, It includes UPF in subnet C that network, which is sliced,.Network slice management equipment can first determine network slice subnet A and network slice subnet B Between transmission demand, network slice subnet A and network slice subnet C between transmission demand and network slice subnet B and Network is sliced the transmission demand between subnet C, and the slice of network slice is determined according to the transmission demand between these subnets The transmission demand of rank.Specifically, network slice management equipment gets network slice subnet A, network slice subnet B and net Network be sliced subnet C between altogether include 5 tie points pair, i.e., gNB1 and AMF, gNB1 and UPF, gNB2 and AMF, gNB2 and UPF, AMF and UPF.Network is sliced management equipment can be according to the information of the tie point pair got and/or the biography of each tie point pair Defeated demand determines the transmission demand of network slice level.
There are also a kind of possible implementation, network is sliced management equipment and is sliced determining network slice level for network When transmission demand, it can be sliced supported demand for services according to the network, determine the corresponding network of network network slice The value range or grade of the transmission demand parameter of slice level.For example, if a network slice is for providing URLLC type Service, network slice management equipment can determine the net according to the high reliability of the service of URLLC type, the demand of low time delay Network is sliced the value ranges of parameters such as the unified throughput of corresponding network slice level, unified propagation delay time or waits Grade.
Certainly, network slice management equipment can be combined with network and be sliced supported demand for services and network slice The transmission demand of middle tie point pair, network are sliced the transmission demand between subnet, determine the corresponding network of network slice The transmission demand of slice level.
In one possible implementation, network is sliced the other transmission demand of sub-network level, may include that first network is cut The mark of piece subnet and the second network slice subnet, optionally, it can also include that network, which is sliced the other transmission demand of sub-network level, One network is sliced the mark of network slice belonging to subnet and the second network slice subnet.Optionally, network is sliced subnet rank Transmission demand can also include that transmission between first network slice subnet and the second network slice subnet when being communicated needs It asks.The other transmission of sub-network level that network is sliced the first network slice subnet that management equipment determines and the second network slice subnet needs It can also include the first transmission performance demand or the first transmission performance demand and the second transmission performance demand in asking.Wherein, One transmission performance demand can be sliced the biography between subnet for creation, modification or release first network slice subnet and the second network Defeated resource, the second transmission performance demand can be sliced the other biography of sub-network level between subnet for the network after to be created or to be modified Defeated performance demand parameters.The other transmission performance demand parameter of sub-network level refers to first network slice subnet and the second network slice Value range or grade or first network the slice subnet of the sum of the transmission performance demand of all tie points pair between net and institute State the unified value range or grade of the performance demand parameters of all tie points pair between the second network slice subnet.
Optionally, the network that network slice management equipment is determined is sliced the other transmission demand of sub-network level, can also include The two networks are sliced the topology information between subnet.The topology information includes the first network slice of connection to be established Connection relationship to be established between the information of network element in subnet and the network element in second network slice subnet, the network element And establish the mark of the tie point pair formed after connection.For example, network slice management equipment can determine that network is sliced subnet 1 In network element 1 and network slice subnet 2 in network element 2 connection relationship.
Specifically, network slice management equipment is determining between first network slice subnet and the second network slice subnet When the other transmission demand of sub-network level, first network slice subnet external transmission demand and the second network can be first determined respectively It is sliced the external transmission demand of subnet, the external transmission demand of subnet is then sliced according to first network and the second network is sliced son External transmission demand is netted, determines that the transmission communicated between first network slice subnet and the second network slice subnet needs It asks.
Wherein, the external transmission demand of first network slice subnet is for the network element in first network slice subnet and except first Transmission demand when network element except network slice subnet is transmitted.For example, as shown in figure 5, including in network slice subnet A GNB1 and gNB2, gNB1 can be connect by transmission network with AMF, can also be connect by transmission network with UPF.Network slice management Equipment can determine the transmission when gNB1 in network slice subnet A is communicated with this network element of AMF to transmission network respectively The transmission demand of transmission network, gNB2 are communicated with this network element of AMF when demand, gNB1 are communicated with this network element of UPF When being communicated to the transmission demand and gNB2 of transmission network with this network element of UPF to the transmission demand of transmission network.
Similarly, the external transmission demand of the second network slice subnet be the network element that is sliced in subnet of the second network with except the Transmission demand when network element except two networks slice subnet is transmitted.As shown in figure 5, including in network slice subnet B AMF1 and UPF1, AMF1 can be connect by transmission network with gNB, and UPF1 can be connect by transmission network with gNB.Network slice pipe Reason equipment can determine the biography when AMF1 in network slice subnet B is communicated with this network element of gNB to transmission network respectively To the transmission demand of transmission network when defeated demand and UPF1 are communicated with this network element of gNB.
Network is sliced management equipment and is determining that first network slice subnet and the second network slice subnet are external respectively After transmission demand, the transmission demand between first network slice subnet and the second network slice subnet is further determined that out.Still with May include the tie point that constitutes of gNB1 and AMF1 for Fig. 5, between network slice subnet A and network slice subnet B to 1, The tie point pair that the tie point that gNB1 and UPF1 is constituted constitutes the tie point that 2, gNB2 and AMF1 is constituted to 3, gNB2 and UPF1 4.If being demand when 20M, gNB2 are communicated with AMF to bandwidth to the demand of bandwidth when gNB1 is communicated with AMF is 10M, and AMF1 It is 10M to the demand of bandwidth when being communicated with gNB, it is determined that going out tie point is to 1 demand of (gNB1 and AMF1) to bandwidth 20M, demand of the tie point to 3 (gNB2 and AMF1) to bandwidth are 10M；If being to the demand of bandwidth when gNB1 is communicated with UPF It is 5M to the demand of bandwidth when 10M, gNB2 are communicated with UPF, and demand when UPF1 is communicated with gNB to bandwidth is 5M, then Determine that demand of the tie point to 2 (gNB1 and UPF1) to bandwidth is 10M, tie point is to 4 (gNB2 and UPF1) to the need of bandwidth It asks as 5M.Then the other bandwidth demand of sub-network level between network slice subnet A and network slice subnet B is (20+10+10+5) M.
In some embodiments, network slice management equipment is sliced for network when determining the other transmission demand of sub-network level, It can be sliced supported demand for services according to the network, determine the other transmission of sub-network level in network slice between each subnet The value range or grade of demand parameter.For example, as shown in fig. 6, network slice subnet A includes gNB1 and gNB2, network slice It include AMF in subnet B, it includes UPF in subnet C that network, which is sliced, is passed since network is sliced between subnet A and network slice subnet B Defeated is control plane information, and transmitting between network slice subnet A and network slice subnet C is user plane information, therefore, net The other transmission demand of sub-network level that network is sliced between subnet A and network slice subnet B can believe control plane according in demand for services The transmission requirement of breath determines that if time delay is X millisecond, and network slice subnet A and network are sliced the subnet rank between subnet C Transmission demand the transmission requirement of user plane information can be determined according in demand for services, as time delay be Y milliseconds.It can also incite somebody to action The priority transmitted between network slice subnet A and network slice subnet B is set as high precedence, and network is sliced son The priority transmitted is set as low precedence between net A and network slice subnet C, when gNB1 and gNB2 generate simultaneously with When the demand that UPF is communicated in the AMF, network slice subnet C in network slice subnet B, if transfer resource is not able to satisfy together When send information, then preferentially to network slice subnet B in AMF send information, then to network slice subnet C in UPF send letter Breath.
Specifically, two can establish the network element that connection is communicated and may be constructed a tie point pair, tie point pair Transmission demand is the transmission demand between two network elements.In order to accurately realize the demand for services of network slice, network slice Management equipment can determine the transmission demand of some or certain tie points to corresponding tie point to rank, so that transmission network Can according to tie point to the transmission demand of rank to corresponding tie point to the transfer resource between two network elements for being included It is configured, to meet its corresponding transmission demand.
It in a specific embodiment, can be to different tie points to different priority is arranged.For example, due to control The priority of face information is higher, and the priority of user plane information is lower, therefore, can be by next-generation base-station node (next Generation node, gNB) with access and mobile management function to ps domain (access and mobility management, AMF) priority of the tie point pair formed is set as high precedence, and by gNB and user plane functions (user plane Function, UPF) priority of tie point pair that is formed is set as low precedence；When gNB simultaneously generate with AMF, UPF into When the demand of row communication, if transfer resource is not able to satisfy while sending information, information preferentially is sent to AMF, then send to UPF Information.
In another specific embodiment, data can also be set to the different types of data packet of the same tie point pair The priority of package level.Such as the data packet transmitted between network element AMF and gNB may include the registration for management terminal, move Dynamic property, establishing session etc., a variety of variety classes, each type of data packet may be because the difference of demand for services and have difference Transmission demand, therefore when AMF to gNB simultaneously different types of data packet and transfer resource anxiety occurs when, can preferentially pass The defeated data packet with more high-transmission demand.
From it is above-mentioned to different tie points to different priority class is arranged seemingly, can also be to different tie points to setting Other the second transmission performance demands such as different time delay, bandwidth, details are not described herein again.
Further, since a tie point is shared to that can be sliced by multiple networks, therefore, tie point is in the different nets of transmission When information in network slice, transmission network can transmit the information according to the transmission demand of the information corresponding network slice.For example, Tie point is sliced A by network to 1 and network slice B shares, and network slice management equipment determines tie point to 1 in transmission network Be sliced A in information when time delay be 0.5ms, and tie point to transmission network slice B in information when time delay be 1ms, Then transmission network should be sliced in B by timing_delay estimation in 0.5ms in transmission network when transmission network is sliced the information in A Information when should be by timing_delay estimation in 1ms.
In a specific embodiment, network slice A includes network element 1 and network element 2,1 He of network element when creating network slice A Network element 2 is it has been established that form tie point to 1；And it is subsequent when creating network slice B, network slice B also contains network element 1 With network element 2, and network element 1 and network element 2 are also required to establish connection in network slice B.Transmission network then between network element 1 and network element 2, A is sliced for network and network is sliced B and establishes a link in logic respectively.Optionally, transmission network network element 1 and network element 2 it Between, a physical link can be only established, or may be that network slice A and network slice B establish a physics chain respectively Road.
In some embodiments, the tie point pair constituted for two network elements, further can also carry out uplink to it With the differentiation of downlink, using uplink and downlink as two tie points pair.It is known as example, network element 1 sends information to network element 2 Row, uplink are correspondingly connected with o'clock to 1；Network element 2 sends information to network element 1 and is known as downlink, and downlink is correspondingly connected with o'clock to 2.It is answered some With in scene, the transmission demand of uplink and downlink be can also be different, and therefore, determine tie point to the transmission demand Shi Ruoneng of rank It enough further determines that out the transmission demand of upstream or downstream and informs transmission network, transmission network is enabled to execute more accurately Uplink and downlink transmission, further satisfaction user demand improve user experience.
As previously described, because the tie point that network slice management equipment is determined can be needle to the transmission demand of rank To the transmission demand for the tie point pair that two network elements are constituted, it is also possible to the tie point of identical two network elements composition in different nets Network slice or network slice subnet in transmission demand, can with the transmission demand of upstream or downstream between identical two network elements, Therefore, the mark for the connection pair that network slice management equipment is determined, can only distinguish the tie point pair which two network element is constituted, Identical two network elements tie point pair for constituting in heterogeneous networks slice or network slice subnet can also can be distinguished, it can be with Distinguish the uplink or downlink between identical two network elements.
For example, tie point can only indicate mark 1 tie point pair that network element 1 and network element 2 are constituted, and it cannot distinguish between the company Contact, if network slice management equipment is wanted to further discriminate between, can make in network slice 1 or in network slice 2 The mark of mark 1+ network slice 2 is distinguished with mark or tie point of the tie point to mark 1+ network slice 1.Again For example, tie point can indicate the tie point pair of network element 1 and network element 2 in network slice 1 to mark A, tie point can to mark B To indicate the tie point pair of network element 1 and network element 2 in network slice 2.For another example tie point indicates network element 1 to network element mark I 2 send transmission link when information, transmission link when tie point indicates that network element 2 sends information to network element 1 to mark II.
In one possible implementation, the transmission demand inside network slice subnet may include network slice subnet The transmission demand of the transmission demand of rank and/or tie point to rank.Specifically, the transmission demand inside network slice subnet is The transmission demand communicated between each network element in one network slice subnet.
Optionally, the network that network slice management equipment is determined is sliced the transmission demand inside subnet, can also include The network is sliced the topological demand inside subnet.In a specific embodiment, if network slice management equipment determine creation or A network slice subnet is modified, network slice management equipment may further determine that in network slice subnet between each network element Wait establish or connection relationship to be modified.
Further, it can also be wrapped in the transmission demand inside network slice subnet that network slice management equipment is determined The first transmission performance demand is included, or may include the first transmission performance demand and the second transmission performance demand.Wherein, it first passes Defeated performance requirement can be sliced the transfer resource inside subnet for creation, modification or releasing network, and the second transmission performance demand can Think it is to be created or to be modified after network slice subnet inside subnet rank and/or tie point the transmission performance of rank is needed Seek parameter.
In a specific embodiment, network slice management equipment determines in network slice subnet for network slice subnet When the transmission demand in portion, the demand for services that subnet is supported can be sliced according to the network, determined corresponding to network slice The transmission demand of network slice level and/or tie point to rank.For example, if a network slice subnet is for providing terminal Access service, network slice management equipment can determine the transmission inside network slice subnet according to the demand of access service Demand；If a network slice subnet is for providing core net function, network is sliced management equipment can be according to core net function Demand determine the network slice subnet inside transmission demand.
In another specific embodiment, network slice management equipment determines that network is sliced subnet for network slice subnet When the transmission demand of inside, the transmission demand that can be sliced the tie point pair that each network element is formed in subnet to the network summarize, and obtain Transmission demand to inside network slice subnet.For example, a network is sliced in subnet including gNB1, gNB2 and AMF, GNB1 and AMF, which can establish connection and form tie point and can establish connection to 1, gNB2 and AMF, forms tie point to 2, then can be with Using tie point to 1 transmission demand and tie point to 2 transmission demand as the network slice subnet inside transmission demand.If Tie point is 10M to 1 and demand of the tie point to 2 pairs of bandwidth, it is believed that the network is sliced the demand inside subnet to bandwidth For 20M；If tie point is 1ms to 1 and demand of the tie point to 2 pairs of bandwidth, it is believed that right inside network slice subnet The demand of time delay is 1ms.
In addition, network slice management equipment can also be sliced the demand for services and the net that subnet is supported according to the network Network is sliced the transmission demand of each tie point pair in subnet, determines the transmission demand inside network slice subnet.
In a specific embodiment, in network slice each network slice subnet external transmission demand or network element biography Defeated demand can be determined that the external transmission demand of the network determined slice subnet is sent to NSMF by NSSMF by NSSMF, Transmission demand NSMF external to each network slice subnet received is integrated, and determines network slice level or sub-network level Not or tie point is to the transmission demand of rank, and the information for the transmission demand that the network determined is sliced is sent to transmission network by NSMF Management equipment.Certainly, above-mentioned NSMF can also be sliced management equipment replacement by other networks.
Step 402, network are sliced management equipment and send network slice transmission management request to transmission network management equipment, this is asked It include the information of above-mentioned transmission demand in asking.
