Embodiment 1

[0021] Such as figure 2 As shown, the embodiment of the present invention provides a method for implementing NF nearby selection, and the method includes the following steps:

[0022] Step S110: The information of the data center DC where the service NF is carried is registered to the corresponding network function repository NRF.

[0023] Specifically, in order to implement disaster recovery and backup of NF, it is usually necessary to deploy NF across different data centers. This has the advantage of ensuring that when a DC's NF is out of service due to some abnormality, the NF in the backup DC can continue to serve users Provide services. Before this step, the following steps need to be performed: network the service NFs under two different DCs through the pool POOL, so that the two service NFs are in a mutual backup relationship. Network the NRFs under two different DCs through the pool POOL, so that the two NRFs are in a backup relationship with each other, and the NF summar...

Embodiment 2

[0037] Such as Figure 5 As shown, the embodiment of the present invention discloses an example of "in the packet data unit PDU establishment process, NRF selects SMF for AMF based on the individual DC information carried", and the specific process is as follows:

[0038] Nodes 101-102: SMF1 and SMF2 are cross-DC mutual backup service NFs, and automatically register with the configured NRF under the respective data center DC when powered on, and the NF summary information requested by Nnrf_NFManagement_NFRegister carries individual DC information. DC information is generally planned by operations and can generally carry administrative area information. For example, JS.NJ and JS.WX represent the numbers of the two DCs of Jiangsu Mobile in Nanjing and Wuxi respectively; for example, the two SMFs of Nanjing and Wuxi respectively report to NRF The registered DC information can be nj.js and wx.js.

[0039] Node 103: After receiving the registration information of SMF, NRF saves the regi...

Embodiment 3

[0043] Such as Image 6 As shown, the embodiment of the present invention discloses an example of "in the packet data unit PDU establishment process, NRF selects SMF for AMF based on the carried DC information implicit in the domain name FQDN information", and the specific process is as follows:

[0044] Nodes 201-202: SMF1 and SMF2 are cross-DC mutual backup NFs, and automatically register with the configured NRFs under their respective DCs when powered on. The FQDN in the NF Profile requested by Nnrf_NFManagement_NFRegister carries the DC information. DC information is generally planned by operations, and can generally carry administrative area information, such as JS.NJ and JS.WX respectively representing the numbers of the two DCs of Jiangsu Mobile in Nanjing and Wuxi. For example, the two SMFs in Nanjing and Wuxi respectively registered FQDNs with NRF as nj.js.smf.5g.3gppnetworks.org and wx.js.smf.5g.3gppnetworks.org.

[0045] Node 203: After receiving the registration informa...

Abstract

The invention discloses a method and equipment for achieving NF nearby selection and a storage medium, and belongs to the technical field of mobile communication. The method comprises the following steps: receiving data center DC information carried by a service NF, and registering the data center DC information to a corresponding network function storage NRF; and receiving an NF discovery requestsent by a consumer NF to the corresponding NRF, and selecting a nearby service NF for the consumer NF through DC information matching. According to the technical scheme provided by the invention, NFdiscovery can be carried out according to the DC information where the NF is located, the flow between the DCs can be reduced while the disaster recovery backup of the NF is ensured, and the interaction time delay is reduced.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method, equipment and storage medium for implementing NF nearby selection. Background technique [0002] The service-oriented architecture is a newly introduced control plane NF (Network Function) architecture in the 5G system by 3GPP (3rd Generation Partnership Project). Under this architecture, the choice between each NF is usually Realized through NRF. 3GPP defines the Nnrf_NFDiscovery (NF Discovery) service for NRF in the TS (Technical Specification) 23.502 protocol to provide NF discovery services. The process of this service is as follows: Consumer NF initiates Nnrf_NFDiscovery_Request (NF discovery request) to NRF , The parameters carried include the destination service name, destination NF type, local NF type, and can optionally carry SUPI (SubscriptionPermanent Identifier), data set identifier, S-NSSAI (Single Network Slice Selection Assistance Inform...
