In order to solve the technical problem, the present application provides a network resource service method, which adds functions of network topology capture, subnet private network identification, application service awareness and the like and data or knowledge services derived from the functions on the basis of the capability of a network resource service network element (for example, 5G NRF, other domain similar network elements) in a network, and realizes the function of enhancing the network resource service to a certain extent. The functions of network topology capture, subnet private network identification, application service perception and the like are supported, so that the requirements of multi-domain, multi-network and multi-service dynamic changes of the network in the future are met.

Referring to fig. 1, the network resource service system includes a network resource service network element, which may also be referred to as a network registration discovery network element, such as a 5G NRF. Based on the network resource service network element, a network topology capture module, a subnet special network identification module and an application service perception module are additionally arranged, the network resource service network element is connected with a core network domain NF and an application domain AF, and then a network resource service center can interact network topology information, service application information, network ID information and the like with the core network domain NF and the application domain AF.

In addition, in the future, the network can also support the information interaction between the network resource service network element and other domains such as a wireless domain NF, a terminal and the like.

In addition, it should be noted that, for example, the settings of the network topology capturing module, the subnet ad hoc network identifying module, and the application service sensing module may be set as independent entity structures, or each module may be set in a network resource service network element.

(3) AMF1 selects SMF, inquires proper SMF from NRF, and carries the following information in the network element discovery request: discovering that the network element type is SMF, supporting video service and supporting service private network a;

(4) NRF determines SMF2 to meet the conditions according to the information in the steps 1a and 1b, and returns the SMF2 to AMF1;
