The service connection relationship of serviceization architecture interface and the service connection relationship of non-serving architecture interface:

In the embodiment of the present application, the service connection relationship of serviceization architecture interface refers to can dynamically be built by service discovery The service connection of vertical service call, the service connection relationship of non-serving architecture interface refer to the network function example at interface both ends The service connection that can be established by static configuration.

Wherein, in the embodiment of the present application, service discovery is specifically referred to, will when network function example A provides certain services Its service provided carries out service registration to service discovery node, so that subsequent other network function examples pass through service discovery section Point can be with Dynamic Discovery this network function example A, and is able to use the service that this network function example A is externally provided.For example, the Two network function examples can provide the second network function corresponding service, thus can by the second network function it is corresponding service to Service discovery node is registered.When the service that first network function example needs to provide using the second network function, first Carry out service discovery request to service discovery node, so service discovery node can be capable of providing to its response needed for service the The address of two network function examples, then first network function example can be to the corresponding second network function example hair of this address Play service call.

Illustratively, as shown in Figure 1 d, because AMF and SMF passes through network storage function (network repository Function, NRF) dynamic service discovery and service call are carried out, so being serviceization architecture interface between AMF and SMF Service connection relationship, NRF are exactly the service discovery node in serviceization architecture network.Wherein, the service that AMF calls SMF to provide When, use the standard interface Nsmf of SMF；When the service that SMF calls AMF to provide, the standard interface Namf of AMF is used.AMF and It is the standard interface Nnrf of the NRF for service discovery between NRF；It is also similarly for service discovery between SMF and NRF The standard interface Nnrf of NRF.

Alternatively, illustrative, as shown in Figure 1 d, eNB is connected in establishment process with the sessions carry of UPF, and processing session is built The SMF of vertical request can select UPF, and the carrying address of eNB is told to selected UPF, then tells the carrying address of UPF ENB, can obtain the address information of other side by SMF between such UPF and eNB and the business for dynamically setting up sessions carry connects It connects, SMF acts as the service discovery node of carrying service during this, and serviceization framework is also corresponded between eNB and UPF and is connect The service connection relationship of mouth.In contrast, SMF and UPF is that service connection is established by static configuration, and eNB and AMF are to pass through Static configuration establishes service connection, therefore is the service connection relationship of non-serving interface between them.Wherein, such as Fig. 1 d institute Show, standard interface of the eNB for establishing service connection with UPF is the N3 interface of eNB, and eNB is used for and AMF establishes service connection Standard interface is the N2 interface of eNB, and standard interface of the AMF for establishing service connection with eNB is the N2 interface of AMF, and UPF is used for It is the N4 interface of UPF with the SMF standard interface for establishing service connection, the standard interface that SMF is used to establish service connection with UPF is The N4 interface of SMF, is described collectively herein, is repeated no more below.

The network architecture and business scenario of the embodiment of the present application description are to more clearly illustrate that the application is implemented The technical solution of example, does not constitute the restriction for technical solution provided by the embodiments of the present application, those of ordinary skill in the art It is found that technical solution provided by the embodiments of the present application is for similar with the differentiation of the network architecture and the appearance of new business scene The technical issues of, it is equally applicable.

Firstly, providing an application scenarios of the embodiment of the present application:

Assuming that operator is in order to support certain a kind of business of client, such as car networking business, VR business or emergency communication industry Business etc. can be one slice template of every a kind of service design, and slice template includes a series of description information, these description letters Breath can be used for creating a specific slice example.It is sliced after the completion of stencil design, operator can determine the slice template A kind of slice of justice is ordered as a slicing product in Web realease and for user, optionally, can also provide a user certain The function of customizing a bit, for example, user can choose the volume of business (number of users as used the business for being suitble to oneself business demand Amount etc.), position or range of the service of offer etc. are also provided.After user orders a slicing product, one will be generated It is sliced order.What slice order described order is which type of one slice, which optional business function has, provide service Position range which has, and supports great business scale etc..Then operator will be user according to slice order Create a slice example, that is, using network function virtualization (network function virtualization, NFV) and the technologies such as the customized network of software (software defined network, SDN) are that client is created that a logic The network of isolation, and corresponding business is opened for user.

Specifically, by taking network is sliced as an example, as shown in Fig. 2, in the prior art, before network slice instantiation, operation Quotient needs physically to add in advance in network slice management function (network slice management function, NSMF) Support grid network is sliced template.The network slice template include NFV deployment needed for NSD or NSD mark (identity, ID) and The business configuration script of network functional entity.Wherein, which includes the business configuration order of network functional entity； The associated description of the NSD can refer to specific embodiment preamble, and details are not described herein.

In the network deployment phase of network slice instantiation, the NSMF entity of operator is sliced order according to network and carries out net Network deployment.Under NFV scene, network deployment mainly by management and layout (management and orchestration, MANO) entity carries out NFV deployment in infrastructure resources, creates the physics between VNF and the different VNF (or PNF) of creation Connection.Specifically, NSD or NSD ID is sent MANO entity by NSMF entity, MANO entity is according to NSD in NFV infrastructure The VNF entity in resource and on-premise network slice is distributed on (NFV I nfrastructure, NFVI), and creates different VNF Physical connection between (or PNF)；Alternatively, MANO entity according to NSD ID after external load NSD, according to NSD in NFVI VNF entity in upper distribution resource and on-premise network slice, and create the physical connection between different VNF (or PNF).

In the service deployment stage of network slice instantiation, business configuration script is sent NE management system by NSMF entity System (element management system, EMS) entity, EMS entity include in network slice according to business configuration script Relevant business configuration order is executed on VNF and PNF, for example interconnected between the network of configuration service on VNF and/or PNF The address agreement (internet protocol, IP), configuration service routing, configuration signal interface parameters, configuration service functional switch Etc., enable network to be sliced the business required in order and is normally behaved on network slice.Wherein, to VNF and/ Or the generating means of the example traffics topology such as PNF are configured, and enable network function that client is forwarded to need to be sliced in network The business of upper carrying, this step are usually referred to as network level business configuration, are described collectively herein, repeated no more below.

However, as described in the background art, existing business configuration script is the example industry according to the slice being pre-designed Business topology is write, and one slice of every deployment, operator requires the example traffic for asking device manufacturer to design slice topology, and compiles Corresponding business configuration script is write, the service deployment of slice, the in this way reality of design slice could be completed according to business configuration script It is very many and diverse and not flexible that the mode of example service topology will lead to entire service deployment process, therefore, how to obtain example traffic Topology is current urgent problem to be solved to promote the flexibility and simplification of service deployment.

To solve this problem, the embodiment of the present application provides the generation method of example traffic topology, allows to be promoted slice The flexibility and simplification of service deployment.Main thought is: the network that the generating means of example traffic topology obtain slice is opened up The generation strategy of the example traffic topology of the logic business topology and slice that flutter, are sliced；Wherein, network topology is for characterizing The network topology being made of the physical couplings between N number of network function example and N number of network function example, logic business Topology is generated for characterizing the network topology being made of the service connection relationship between M network function and M network function Whether strategy allows to establish service connection, M, N between any two network function example in N number of network function example for characterizing It is positive integer；The generating means of example traffic topology generate slice according to network topology, logic business topology and generation strategy Example traffic topology, wherein example traffic topology for characterize N number of network function example and N number of network function example it Between service connection relationship constitute network topology.

Wherein, the network topology of above-mentioned slice can be the network topology designed of slice design phase, be also possible to It, can also be in slice example at the network topology that the generating means of example traffic topology after the network deployment of slice example obtain The network of the scene for network topology change of the generating means dynamic acquisition of example traffic topology, which is disposed, in operational process adjusts Network topology after whole, the embodiment of the present application are not especially limited this.Similar, the logic business topology of above-mentioned slice can be with Be be sliced the design phase design logic business topology, can also slice example operational process in example traffic topology The logic business topology for redesigning out for the scene of logic business change in topology of generating means dynamic acquisition, the application Embodiment is not especially limited this.

Illustratively, it is assumed that the network topology of current slice is as shown in Figure 3a.Wherein, eNB1, AMF are deployed in the A of city The network functions examples such as entity 1, SMF entity 1, UPF entity 2 and UPF entity 1；Be deployed in the B of city eNB2, AMF entity 2, The network functions examples such as SMF entity 2 and UPF entity 3, NRF entity is as service discovery node, positioned at the weight of city A and city B Region is folded, the physical couplings between each network function example are as shown in Figure 3a, no longer describe one by one herein.

Assuming that, since city B will hold grand performance, causing the portfolio of slice anxious in the operation phase of slice example Increase severely and add, as a result as shown in Figure 3b.Wherein, the dotted line in Fig. 3 b indicates newly-increased network function example or physical couplings. At this point, the generating means of example traffic topology need to obtain network topology shown in Fig. 3 b, and automatically generated according to above scheme The example traffic topology of slice, the service deployment of slice can be completed according to the example traffic topology again.

S708, logic business topology processing entities are opened up to the logic business that the generating means of example traffic topology send slice It flutters, so that the generating means of example traffic topology receive the logic business topology from logic business topology processing entities.

S709, example traffic topology generating means any two network function example is taken out from network topology, here Assuming that any two network function example is first network function example and the second network functional entity.

S710, the generating means of example traffic topology are topological according to logic business, determine that first network function example is corresponding First network function and corresponding second network function of the second network function example between whether there is service connection relationship.

If it exists, step S711 is continued to execute；If it does not exist, go to step S715.

S711, example traffic topology generating means according to network topology, determine first network function example and the second net It whether there is physical couplings between network function example.

If it exists, step S712 is continued to execute；If it does not exist, go to step S715.

S712, example traffic topology generating means to external policy entity sending strategy request message so that external The policy request message of generating means of the policy entity reception from example traffic topology.Wherein, which carries The attribute information of first network function example, the attribute information of the second network function example and first network function example and At least one of the attribute information of physical connection between second network function example, for request first network function example and Whether allow to establish the strategy of service connection between second network function example.

Condition 3: the generating means of example traffic topology determine first network function example and the second net according to generation strategy Allow to establish service connection between network function example.

It should be noted that above-mentioned steps S710-S714 is merely exemplary first to determine whether to meet condition 2, it is rear true It is fixed whether to meet condition 1, finally determine whether to meet condition 3, so that the generating means for giving a kind of example traffic topology are true Be scheduled on slice example traffic topology in there are service connection passes between first network function example and the second network function example The specific implementation of system, but the embodiment of the present application does not limit and determines whether to meet the successive suitable of above-mentioned condition 1, condition 2 and condition 3 Sequence, for example can also be and first determine whether to meet condition 1, after determine whether to meet condition 2, finally determine whether to meet condition 3, Etc., this is no longer going to repeat them.

S715, example traffic topology generating means continue since step S709, loop through network topology in own Network function example.

In having traversed network topology after all network function examples, the example traffic topology of slice can be obtained.

Wherein, the generating means of example traffic topology obtain slice network topology, slice logic business topology, with And after the generation strategy of the example traffic topology of slice, according to network topology, logic business topology and generation strategy, generation are cut The pseudocode of the example traffic topology of piece can be expressed as follows:

It should be noted that the thought of the pseudocode of the example traffic topology of above-mentioned generation slice is:

With there are how many a network function examples in the generating means identification network topology of example traffic topology, and with any The network function example in network topology is numbered in sequence, such as first network function example, the second network function example Deng.

Then, since first network function example, determine that the first network function is real according to logic business topology respectively The corresponding first network function of example network function corresponding with other network function examples whether there is service connection relationship；According to Network topology determines between the first network function example and other network function examples with the presence or absence of service connection relationship；According to Whether generation strategy determines allows to establish business between the first network function example and the second network function example.

Then, then from the second network function example, the above-mentioned operation for first network function example is executed, until network All-network function example in topology, which traverses, to be completed.

Generation method based on example traffic topology provided by the embodiments of the present application, on the one hand, due to the embodiment of the present application The example traffic topology that slice can be automatically generated by the generating means of example traffic topology, can according to the example traffic topology With the further service deployment for completing slice.When network topology or logic business topology or generation strategy change, it is only necessary to Network topology or logic business topology or generation strategy after reacquiring change, regenerate example traffic topology i.e. It can.It does not need as the prior art, when each network topology or logic business topology or generation strategy change, all It needs manufacturer personnel to redesign the example traffic topology of slice, and corresponding business is write according to the example traffic topology of slice Configuration script could complete the service deployment of slice, so that the embodiment of the present application can promote the flexibility of slice service deployment With simplification.On the other hand, the logic business of the information of the network topology of slice and the slice is opened up due to the embodiment of the present application The information flutterred is arranged in a slice template, since the slice template is set in advance by manufacturer personnel or slice operation maintenance personnel It has been set that, therefore be based on the program, the versatility and portability of slice service deployment can be promoted.On the other hand, due to this The generation strategy for applying for the example traffic topology in embodiment is external generation strategy, and external policy can be according to client's What demand was formulated, and be easily achieved, therefore be based on the program, use can be easy to implement under the premise of not increasing realization difficulty The personalized demand of slice is intervened at family without manufacturer.In another aspect, due to any two net in determining network topology When whether there is service connection relationship between network function example, above-mentioned condition 1 is considered from network condition angle, above-mentioned item Part 2 is considered from business demand angle, and above-mentioned condition 3 is considered from customer demand angle.That is, the embodiment of the present application Mode in the determination network topology of offer between any two network function example with the presence or absence of service connection relationship is examined simultaneously Network condition, business demand and customer demand are considered, therefore in the determination network topology between any two network function example With the presence or absence of service connection relationship mode consider more comprehensively and it is complete, so as to further promote the example traffic of generation The accuracy of topology, and then can further promote the accuracy of service deployment.

Wherein, the movement of the generating means of example traffic topology can as shown in Figure 6 into S715 by above-mentioned steps S701 Processor 601 in the generating means 600 of example traffic topology calls the application code stored in memory 603 to hold Row, the embodiment of the present application are not intended to be limited in any this.

Optionally, embodiment shown in Fig. 7 is from external policy entity with the generation strategy for the example traffic topology being sliced It is illustrated for the external generation strategy of acquisition.Certainly, the generation strategy of the example traffic topology of slice can also be following Situation:

Situation one: the generation strategy of the example traffic topology of slice is the default generation strategy being sliced in template.Due to this Slice template is to be set in advance by manufacturer personnel or slice operation maintenance personnel, therefore be based on the program, can promote slice The versatility and portability of service deployment.

The generation strategy of situation two, the example traffic topology of slice is determined by default generation strategy and external generation strategy: For example, high priority strategy can be set by external generation strategy by way of priority, in this way, when example traffic is opened up When the generating means flutterred get external generation strategy, by the outside, generation strategy is set as the generation plan of example traffic topology Slightly；Alternatively, the generation strategy etc. of example traffic topology can also be collectively constituted by default generation strategy and external generation strategy. Since the generation strategy of example traffic topology is determined by default generation strategy and external generation strategy, not only provide the user with It can be more alternative；And it since external policy can be according to the formulation of the demand of client, and is easily achieved, therefore can Under the premise of not increasing realization difficulty, to be easy to implement user for the personalized demand of slice, intervened without manufacturer.

Optionally, the external generation strategy in the embodiment of the present application can be the external generation obtained from external policy entity Strategy；Alternatively, the external generation strategy in the embodiment of the present application can also be the generating means of example traffic topology according to outside The external generation strategy that the policy depiction information of input determines, the embodiment of the present application are not especially limited this.

Optionally, embodiment shown in Fig. 7 is when obtaining external generation strategy, to any two in network topology When network function example is handled, obtains and be illustrated for the two corresponding generation strategies of network function example.Certainly, The generating means of example traffic topology are also possible to once obtain the external generation strategy of entire example traffic topology, and the application is real It applies example and this is not especially limited.

It optionally, can also include: example industry after generating the example traffic topology of slice in the embodiment of the present application The generating means of business topology obtain the standard interface information of N number of network function example；And it is connect according to example traffic topology and standard Message breath, generates the service configuration information of slice.

Since the program does not need manually to write corresponding business configuration script to the example traffic topology of slice, but can According to the service configuration information of example traffic topology and standard interface Automatic generation of information slice, that is to say, that may be implemented Automatic service deployment, therefore the flexibility and simplification of slice service deployment can be promoted.

Optionally, in the embodiment of the present application, the generating means of example traffic topology connect according to example traffic topology and standard Message breath, generates the service configuration information of slice, can specifically include: for any non-serving frame in example traffic topology The service connection relationship of structure interface, the generating means of example traffic topology are according to for third network function example and the 4th net The mode of the service connection relationship of non-serving architecture interface between network function example is handled:

According to the interface message of third network function example in standard interface information, the is generated for third network function example One service configuration information；And the interface message according to the 4th network function example in standard interface information, it is the 4th network function It can example the second service configuration information of generation；

Alternatively, for the service connection relationship of any serviceization architecture interface in example traffic topology, example traffic is opened up The generating means flutterred are according to for the service architecture interface between the 5th network function example and the 6th network function example The mode of service connection relationship handle:

According to the interface message of the 5th network function example in standard interface information, third industry is generated for service discovery node Business configuration information；And the interface message according to the 6th network function example in standard interface information, it is raw for service discovery node At the 4th service configuration information, wherein third service configuration information passes through service discovery node for the 5th network function example It was found that the 6th network function example, the 4th service configuration information is found for the 6th network function example by service discovery node 5th network function example.

Since the service connection relationship of non-serving architecture interface refers to that the network function example at interface both ends can pass through The service connection that static configuration is established, therefore for the non-clothes between third network function example and the 4th network function example It can be respectively third network function example and the 4th network function when the service connection relationship of businessization architecture interface is handled Example generates corresponding service configuration information, so as to complete corresponding business configuration；Due to the industry of serviceization architecture interface Business connection relationship refers to the service connection that service call can be dynamically established by service discovery, therefore is being directed to the 5th network function It is for clothes when the mode of the service connection relationship of serviceization architecture interface between energy example and the 6th network function example is handled Business discovery node generates corresponding service configuration information, which is used for the 5th network function example and the 6th network It is mutually found between function example, so as to complete corresponding business configuration.

Illustratively, according to Fig. 1 d it is found that the service connection relationship between eNB and AMF is non-serving architecture interface Service connection relationship, therefore the service connection relationship between eNB2 the and AMF entity 2 in Fig. 1 c is non-serving architecture interface Service connection relationship, then the generating means of example traffic topology can generate business according to the N2 interface message of eNB2 for eNB2 Configuration information；And the generating means of example traffic topology can be raw for AMF entity 2 according to the N2 interface message of AMF entity 2 At service configuration information.

Alternatively, it is illustrative, according to Fig. 1 d it is found that the service connection relationship between SMF and AMF is serviceization architecture interface Service connection relationship, therefore the service connection relationship between the SMF entity 1 in Fig. 1 c and AMF entity 1 be non-serving framework The service connection relationship of interface, then the generating means of example traffic topology can be according to the Nsmf interface message of SMF entity 1 NRF entity generates service configuration information 1；And the generating means of example traffic topology can be according to the Namf interface of AMF entity 1 Information generates service configuration information 2 for NRF entity.Wherein, service configuration information 1 is found for SMF entity 1 by NRF entity AMF entity 1, service configuration information 2 find SMF entity 1 by NRF entity for AMF entity 1.In turn, NRF entity is being handled When the service discovery request of each network function example, it can realize and business is opened up according to the service configuration information of NRF physically The control flutterred, for example when AMF entity 1 is to NRF entity requests SMF service discovery, NRF entity is being responded according to service configuration information The services addresses of SMF entity 1 only are provided to AMF entity 1 in message, without providing the services addresses of SMF entity 2.
