Specific embodiment
The embodiment of the present application provides uniform resource locator addressing method and device, network system, to service for 5G
The service access person changed in network addresses network function unit appropriate, provides reliable technical side to service access addressing
Case.
5G core net uses serviceization framework, and core net function is divided into multiple network functions by reconstruct.Network function pair
It is presented in a manner of service outside, serviceization interface is used between network function, 5G core net process is also further broken into more
The demand of user is completed in the combination of a service by the service entities of multiple and different functions jointly by certain Services Composition.For
Realizing can be called by other network functions, and network function after initialization is complete, needs to network storage function
The service of its offer of (Network Repository Function, NRF) registers entities.Network function (Network
Function, NF) entity is before calling other network functional entities, it is also desirable to pass through the other network functions of NRF object query
The service and resource descriptor that entity provides include the address of service access in resource descriptor, and 3GPP arrange this at present
The set-up mode of address is unfavorable for service arrangement or adjustment if being arranged to fixed IP address, and uses the side of domain name
Formula, the then configuration for the domain name that needs to standardize and analysis mode.The setting of address directly affects the access and deployment of service, is 5G clothes
Matter of utmost importance relevant to realization in businessization framework.
Serviceization framework and serviceization interface realize the decoupling between network element, same in the flexibility of enhancing service access
When, safety issue is also brought, third-party application can get network by the information and correlation of serviceization interface
Topological structure, network may further targetedly be attacked.
In the embodiment of the present application, proposes and utilize RESTful hypertext transfer protocol under the 5G serviceization network architecture
(HyperText Transfer Protocol, HTTP) uniform resource locator (Uniform Resource Locator,
URL it is single to increase addressing by being defined to RESTful HTTP URL in a network for the method and apparatus) being addressed
Member is parsed and is decomposed to URL, and the services mechanism such as composite services discovery, service registration, load balancing, realizes topology
It hides and (is acted on behalf of by IP, Network Isolation is realized, so that topology situation be can't see in outside.To reach hiding network topology structure
Purpose) and distribute optimal service rendering units (or ISP) in network for consumer.Wherein, REST
(Representational State Transfer, abbreviation REST) refers to one group of framework constraint condition and principle.Meet this
The application program or design of a little constraint conditions and principle are exactly RESTful.
5G network will use serviceization framework as unique form of the 5G network architecture.By being done newly to former network function
Modularized design, network function is split into disparate modules, and make mutually to decouple between disparate modules, with the interface of serviceization
Signaling of the network element to network element before replacing.In whole process, it is more concerned with and regards network behavior as single service or multiple
The combination of service, so that the interaction between network element is more efficiently direct.In the network architecture of 5G core net, control plane passes through network
Control plane is divided into multiple network functions: access and mobile management function to ps domain according to the difference for realizing function by function remodeling
(Access and Mobility Management Function, AMF), the relevant function (Session of session management
Management Function, SMF), the relevant function of tactical management (Policy Control Function, PCF), uniformly
Data management (Unified Data Management, UDM), authentication service function (Authentication Server
Function, AUSF), terminal traffic message forward relevant function (User Plane Function, UPF), connect with serviceization
Mouth carries out the interaction of 5G operation flow, the processes such as the registration of controlling terminal and session establishment, and is compiled by serviceization application program
Journey interface (Application Programming Interface, API) interface provides 5G network capabilities to application and business and opens
It puts.
The function of plane, such as AMF and SMF are controlled, in the form of services for the other function module tune in control plane
With.Under serviceization framework, the function of plane is controlled either the producer (producer) serviced, is also possible to disappearing for service
The person of expense (consumer).To there are the functions of multiple consumers, and serviceization to be taken to design, the reusability of function can be improved, simplify
Business Process Design, Optimal Parameters transmission efficiency improve the overall flexibility of network control function.
Service interface is defined as follows:
NF is serviced to authorization consumer and is provided a kind of ability.Network function can provide different abilities, thus for not
Same consumer provides different NF services.It is independent for being serviced by each NF of network function offer, repeat
It uses.One operation flow can be constructed by a series of NF service.
Service interface includes two class basic operations:
1) " request-response ":
Referring to Fig. 1, a control plane NF_A (NF service consumer) requires control plane NF_B (NF service producer) to provide
Certain NF service may include execution movement and/or offer information.NF_B responds the letter provided in its request according to NF_A
Breath provides NF service result.In order to meet this requirement, NF_B can consume the service of the NF from other NF.In request response machine
In system, communication is one-to-one between two NF (consumers and producers), and expected generate within a certain period of time corresponds to
The disposable response from the producer to consumer of request.
2) " Subscribe-Notify ":
Referring to fig. 2, control plane NF_A (NF service consumer) is subscribed to by another control plane NF_B (NF service producer)
The NF of offer is serviced.Multiple control plane NF can subscribe to identical control plane NF service.The result notice that NF_B services the NF
Subscribe to the interested NF of NF service.Subscription request from consumer may include the periodicity triggered by certain events
It updates or notifies (for example, the information change of request, reaches some threshold value etc.).This mechanism, which also covers NF (NF_B), not to be had
The case where impliedly subscribing to certain notices in the case where clearly subscribing to request (such as due to successful registration process).
Each function device of 5G network needs to carry out service interaction according to the mode of the above serviceization interface.Specifically such as
Under:
Referring to Fig. 3, service registration:
NRF provides NF discovery service, and the NF example information being found is provided by service registration.
Service registration may include two ways:
Static configuration: NRF is supplied to by way of configuring by operation and maintenance management system (OAM).
Dynamic registration: it after NF instantiation to be registered, is registered by NRF " service registration " service interface to NRF.
The following describe a kind of reference schemes for realizing service dynamic registration management:
Information for the network function example for making NRF maintain to dispose needs to pass through service in on-premise network function example
The information of network function example is supplied to NRF by registration.In offloading network function example, need to go registration notification by service
NRF deletes the network function example information saved.Network function example information includes the corresponding network function of network function example
The information such as the service that type (such as AMF, SMF etc.), the address of network function example, network function are supported.
The service interface that NRF should support service registration, go registration, makes NF service registration request person (such as network management system) can
To request the registration of network function service by the service interface and go to register.
In some network function example deployment, service requester such as network management system sends NF registration request to NRF
(Registration Request) message request executes NF service registration, includes corresponding network function example in request message
Information.
NRF saves the information of the network function example of deployment.
NRF registers response (Registration Response) message informing NF service registration by NF and has completed.
In the unloading of some network function example, referring to fig. 4, service requester such as network management system sends NF to NRF and goes
Registration request (Deregistration Request) message request executes NF service and goes to register, and includes corresponding in request message
The mark etc. of network function example.
NRF deletes the information of the corresponding network function example of its preservation.
NRF goes registration response (Deregistration Response) message informing NF service to go registration by NF
It completes.
Service update process is as follows:
It is serviced after upgrading referring to Fig. 5, NF, need to initiate interaction flow to NRF and updates NF information on services.
The scene may be caused by NF service upgrade version and functional configuration, after upgrading successfully, from NF actively to NRF
The service of transmission updates request, and the information of NF is passed to NRF.
NRF saves NF up-to-date information, and returns to NF upgrading response.
Service authentication:
Agreement between strategy, the strategy from service provider, operator according to NF is carried out authorization service by NF authorization of service
Requestor NF access is serviced by the NF that ISP NF is provided.
Service authorization information is a part in the configuration file of NF, it includes the NF type for allowing to be connected with the NF, with
And it can be serviced by the corresponding NF of those NF type of access.
Authorization of service includes two steps:
Check whether requestor NF is allowed to find requested NF example during NF service discovery process.This is NF
Degree.
Check whether requestor NF is allowed access to requested NF to use its NF to service.
Service discovery:
Network function (NF) in core network can via the interface based on service by the ability of NF in a manner of servicing
It is exposed, and can be reused by other NF.
NF service discovery makes the NF for controlling plane it can be found that providing the specific objective NF example of desired NF service.Pass through
NF has found to realize NF service discovery.NF has found so that service requester NF is it can be found that ISP's NF example, and accesses
The NF service provided by ISP NF.
Referring to Fig. 6, the service to provide some NF is found and is used by other NF, need to rely on NRF this
One service register center is coordinated, and the discovery for the first time of service (including Service Instance) is completed.In conjunction with NRF, the possibility of interaction between service
Mode is as follows.By taking the signing information between AMF and UDM obtains as an example.
The deployment of serviceization is very flexible.Service consumer can realize searching clothes by processes such as service discoveries
It is engaged in the location information of supplier, and realizes by RESTful HTTP service message the access of service process.Therefore, this Shen
Please embodiment propose the method and apparatus being addressed using RESTful HTTP under a kind of 5G serviceization network architecture, it is right
