In step S612, the SUPI number segment configuration system identifies the area identifier of the area to which the UDM belongs based on the IP address.
In step S614, the SUPI segment configuration system determines at least one set of SUPI segment data matching the area identifier based on the mapping relationship.
In step S616, the SUPI field configuration system sends at least one set of SUPI field data to the UDM.
In step S618, the UDM receives at least one set of SUPI number segment data fed back by the SUPI number segment configuration system based on the acquisition request.
In step S620, the UDM determines a corresponding start value and a corresponding cutoff value for any group of SUPI number segment data, and generates subscription information based on the SUPI number data between the start value and the cutoff value and the belonging area, so as to complete configuration operation based on the subscription information.
In step S622, the UDM sends a registration request to the corresponding network warehousing function NRF based on at least one set of SUPI number segment data to perform a network element registration operation.
In this embodiment, SUPI field data of national fields is centrally managed and maintained by introducing a SUPI field configuration system storing SUPI fields in a national center, each of which corresponds to a province to which it belongs.
Specifically, when an intra-provincial maintenance person performs UDM network element number configuration, the network element calls the current number section data stored in the system to the SUPI number section configuration system. And the system confirms the province of the network element according to the IP address of the request network element. And sending the initial value and the cut-off value of each number segment of the province, which are stored in the system, to the network element, and performing number segment configuration on the acquired data by the UDM, and after the number segment configuration is completed, the UDM completes the registration of the network element to the NRF. And subsequently, when the network element of the consumer discovers the UDM, the UDM registration information carrying the correct number segment can be discovered.
The SUPI number segment configuration scheme effectively solves the problem that the situation that a consumer network element dynamically discovers a wrong number segment due to number segment configuration errors in the UDM registration process is not effectively avoided at present, national number segment data is maintained and managed through the SUPI number segment configuration system, the uniqueness and the accuracy of the data are ensured, when the number segment configuration is carried out on UDM equipment in all provinces in China, the SUPI number segment configuration system is uniformly requested to acquire the number segment data belonging to the province, the accuracy of the network element number segment configuration is improved, the prepared number segment information can be ensured to be obtained in the network element registration and network element discovery processes, and the situation that a user cannot use services due to the network side number segment configuration errors is avoided.
