Technical solution of the present invention is described in detail with specifically embodiment below.These specific implementations below Example can be combined with each other, and the same or similar concept or process may be repeated no more in some embodiments.

As a key characteristic of 5G, 5G network can be divided into multiple network slices.One network slice is one corresponding Logical network, the logical network are used to meet the communication service demand of a use-case (use case).One network slice is by more A network function (network function) composition, the realization of a network slice in a network is by instantiating these nets Network function and then instantiation network slice.In other words, a network slice is to be sliced example (network slice by network Instance, NSI) Lai Shixian, i.e., each network function example (the network function being sliced by network Instance, NFI) and corresponding resource distribution constitute.Different NSI can have different NFI and/or resource distribution.One A network slice further can also be sliced subnet comprising multiple networks, and a network slice subnet is a network slice root The part divided according to certain criterion (such as deployment region, function division, equipment supplier).Correspondingly, NSI can be with Comprising multiple networks be sliced subnet example (network slice subnet instance, NSSI), a NSSI by one or Multiple NFI compositions.

Network function is the processing function in a kind of network, has specific function sexual behavior and interface.From the angle of realization Degree is seen, network function can be divided into physical network function and virtual network function.From the point of view of use, network function can be with It is divided into privately-owned network function (non-shared network function, NNF) and shared network function (shared network function,SNF).When a network function is pertaining only to (support) network slice/network slice subnet, The network function is NNF；When a network function belongs to (support) multiple network slices/network slice subnet, the network function It can be SNF.One network function be by network function example (network function instance, NFI) Lai Shixian, Therefore NNF is realized by NNFI, and SNF is realized by SNFI.Further, NFI can be realized by specialized hardware, Can also by specialized hardware runs software realize, can also be real in the form of virtual machine on general hardware platform It is existing.

There are a plurality of types of network functions, such as access and mobile management function to ps domain (access and for 5G network Mobility management function, AMF), conversation management functional (session management function, SMF), network is sliced selection function (network slice selection function, NSSF), user plane functions (user Plane function, UPF) and policy control functions (policy control function, PCF) etc..Some network functions It can be by multiple network slices/shared use of network slice subnet, such as AMF, NSSF.For this SNF, inventors have found that Although multiple network slices/network slice subnet can be shared using one or more network functions, for business, peace Entirely or performance guarantee etc. considers, these network slices/network slice subnet needs in logic or physically to carry out part/all Isolation, therefore for these network slices/shared SNF used of network slice subnet, it may be necessary in the multiple nets being shared The isolation in logical/physical is carried out between network slice/network slice subnet, to meet heterogeneous networks slice/network slice subnet Between safety or performance requirement.

For example, the first NSI is the automatic Pilot NSI that motor corporation A is provided to wireless network, the 2nd NSI is motor corporation B The automatic Pilot NSI provided to wireless network.For considering for commercial interest, motor corporation A and motor corporation B are to wireless network Operator proposes demand, and respective automatic Pilot NSI needs to be isolated, and cannot have the shared SNF example used.In order to safeguard nothing The safe operation of each automatic Pilot NSI in gauze network, third of the wireless carriers creation in emergency circumstances alarming NSI.In this case, the terminal user of the first NSI and the 2nd NSI requires to use the 3rd NSI simultaneously.Therefore, the first NSI At least exist a SNF (referred to as the first SNF) with the 3rd NSI, the 2nd NSI and the 3rd NSI also at least have a SNF (referred to as 2nd SNF), and the first SNF and the 2nd SNF function having the same, but need to be that physical/logical is isolated.In other words, One SNF and the 2nd SNF is the network function (being such as AMF, NSSF) of same type, but the two cannot be same total again Enjoy network function example (shared network function instance, SNFI).For another example the first NSI is for high speed The terminal user of train provides the NSI of service on net, and the 2nd NSI is that the NSI of Video service, third are provided for indoor terminal user NSI be all terminal users require using default NSI.In this case, part terminal user needs to use the simultaneously One NSI and the 3rd NSI；Another part terminal user needs while using the 2nd NSI and the 3rd NSI.Due to the first NSI and second NSI for certain SNF (such as AMF) demand there are larger difference, for example the AMF function that the first NSI is required is far longer than second The AMF function that NSI is required, the first NSI and the 2nd NSI need to provide clothes using two AMF of isolation for respective terminal user Business, and the two AMF are required by the shared use of the 3rd NSI.For above-mentioned two example, three NSI have mutually similar The SNF of type, but the same SNFI cannot be used.The wherein SNF of the first NSI and the 3rd NSI corresponding a SNFI, the 2nd NSI Another SNFI is corresponded to the SNF of the 3rd NSI.In other words, for the 3rd NSI, two SNFI is at least needed to realize itself and its He is NSI shared SNF.

For this purpose, the embodiment of the present application provides a kind of technical solution for managing SNF, so that network slice/network slice The isolation requirement of net is protected.

Fig. 2 shows a kind of configuration diagrams of network slice management system provided by the embodiments of the present application, including communication Service management function (communication service management function, CSMF), network are sliced management function (network slice management function, NSMF) and network are sliced subnet management function (network slice subnet management function,NSSMF).Wherein, CSMF is mainly responsible for operator and/or third party client Communication service demand is converted into the demand to network slice, and passes through the interface between NSMF and send to NSMF to network slice Demand (such as request creation, termination, modification NSI)；Management data (such as performance, number of faults that network is sliced are obtained from NSMF According to etc.), generate the management data for running on the communication service on NSI；And operator and/or third party client are received to net Network slice management data and/or the subscription demand of management data of communication service etc..Optionally, CSMF is by multiple subfunction moulds The logic administrative unit that block is composed, wherein sub-function module is alternatively referred to as atomic function module (atomic function block,atomic building block).Sub-function module includes but is not limited to Service Instance (service instance) Life cycle management module, Service Instance performance management module, Service Instance fault management module, Service Instance test and management mould Block, Service Instance Data analysis and reporting module, network management data subscribing module, demand for services negotiation module and charging Module etc..It should be noted that Service Instance is the running terminal user's industry realized by NSI or provided by NSI Business or commercial occupation.It should be understood that the title of each equipment is exemplary in network slice management system architecture diagram shown in Fig. 2 , such as network slice management function is also possible to Network Management System, network is sliced management system etc., the embodiment of the present application pair This is not construed as limiting.

NSMF is mainly responsible for the network slice demand that CSMF is sent that receives；The composition of layout NSI；To the life cycle of NSI, Performance, failure etc. are managed and (below referred to as manage life cycle, performance, fault management)；It is each for decomposing the demand of NSI The demand of NSSI and/or network function；And NSSI management request etc. is sent to each NSSMF.Optionally, NSMF is by multiple sons The logic administrative unit that functional module is composed, wherein sub-function module include but is not limited to NSI life cycle management module, NSI performance management module, NSI fault management module, NSI test and management module, the analysis of NSI data and reporting module, network pipe Manage data subscription module, slice requirement negotiation module and accounting module etc..

NSSMF, which is mainly responsible for, receives the NSSI regulatory requirement that NSMF is sent；NSSI is managed；The group of layout NSSI At；The demand for decomposing NSSI is each network function and/or the demand of nesting NSSI, and may be sent to other NSSMF nested NSSI management request.It should be noted that nesting NSSI just refers to that the NSSI is the component part of another or multiple NSSI, i.e., The NSSI is a subset of its another or the multiple NSSI that are nested in.Optionally, NSSMF is by multiple sub-function modules The logic administrative unit being composed, wherein sub-function module includes but is not limited to NSSI life cycle management module, NSSI Energy management module, NSSI fault management module, NSSI test and management module, the analysis of NSSI data and reporting module, network management Data subscription module, slice subnet requirement negotiation module and accounting module etc..

NSSMF can be there are many mode to the management of network function.In one possible implementation, NSSMF is direct Manage network function or the network equipment.In this case, NSSMF is also possible to domain manager (domain manager).Such as Fruit NSSMF is made of multiple sub-function modules, then NSSMF may also include network function fault management module, network functionality It can management module, network function configuration management module, (virtual) network function life cycle management module, network function self-organizing Network management module, network function safety management module and network function billing management module etc..In alternatively possible reality In existing mode, NSSMF manages network function or the network equipment by network function management module.In this case, NSSMF can To interact with network function management module (such as NE Explorer (element manager)), and pass through network function pipe Manage module management network function or the network equipment.

It should be understood that being the feelings for the logic administrative unit being composed of multiple sub-function modules in CSMF/NSMF/NSSMF Under condition, between any sub-function module in Different Logic administrative unit there is independent interface to be communicated.For example, CSMF Both there is first interface to realize between Service Instance life cycle management module and the NSI life cycle management module of NSMF Between communication；Similarly, have the between the Service Instance performance management module of CSMF and the NSI performance management module of NSMF Two interfaces are to realize communication between the two.

Fig. 3 shows a kind of implement scene for managing shared network function provided by the embodiments of the present application.In this scenario, First network slice and the second network slice are already existing two networks slices in network, also referred to as existing (existing) Network slice.Wherein, first network slice and the second network are sliced shared first SNF.In other words, is contained in the first NSI The first SNFI is also contained in one SNFI, the 2nd NSI.In this scenario, it in order to meet the needs of different user, needs in network Middle creation third network slice, wherein the third network slice to be created needs and the second network slice is shared and the first SNF SNF with identical network function type, but the SNF can only be sliced by the second network and third network is sliced and shares, it cannot It is shared by first network slice.Therefore, the 3rd NSI and the 2nd NSI is needed comprising having the function of identical network class with the first SNFI Type but independent 2nd SNFI.As shown in figure 3, the 2nd SNFI and the first SNFI are logical/physical isolation, i.e., the two is phase The network function of same type, but be logical/physical equipment independent.Correspond to example above-mentioned, first in Fig. 3 NSI is that the automatic Pilot NSI, the 2nd NSI that motor corporation A is provided to wireless network are wireless carriers creations for tight The NSI to alarm in anxious situation, the 3rd NSI are the automatic Pilot NSI that motor corporation B is provided to wireless network.For motor corporation A Automatic Pilot NSI user for, connect network after need pass through the first SNFI simultaneously access the first NSI and the 2nd NSI；It is right For the user of the automatic Pilot NSI of motor corporation B, needs to pass through the 2nd SNFI after connecting network while accessing the 2nd NSI With the 3rd NSI.In this way, not only ensure that mutually isolated between the automatic Pilot NSI of motor corporation A and motor corporation B offer but also true The user for protecting two automatic Pilot NSI can access alarm NSI simultaneously.Fig. 3 only example go out between the first NSI and the 2nd NSI and There was only the case where a type of SNF between 2nd NSI and the 3rd NSI.It should be understood that in real network, different NSI it Between can also have multiple same types or different types of SNF, this is not construed as limiting herein.Wherein, have between different NSI more The SNF of a same type indicates to share a type of SNF between multiple NSI, but the SNF of the type in a network can be with It is realized by multiple SNFI, the effects of these SNFI can provide such as load balancing；Between different NSI have it is multiple not The SNF of same type indicates to share a plurality of types of SNF (such as AMF, NSSF, UPF), each type of SNF between multiple NSI It can be realized by one or more SNFI.
