[0125] Based on the global network layer corresponding to the ecological integration domain, configure the target area with a network type that matches the terminal positioning technology in the terminal information and the basic network equipment corresponding to each network type;

[0126] According to the target environment information, detecting a signal strength interval using a preset reference positioning technology in each sub-area; the signal strength interval includes at least a maximum signal strength;

[0127] According to the regional environment information corresponding to each sub-region and the signal strength interval corresponding to each sub-region, a target sub-region that meets the preset signal enhancement conditions is screened out from all sub-regions;

[0128] For each target sub-area, based on the global network layer, a signal strengthening network device matching the preset signal strengthening condition is configured for the target sub-area;

[0129] Among them, all network devices include basic network devices, or network devices include basic network devices and signal enhancement network devices.

[0132] For example, taking the target scenario of a smart port as an example, the port environment is relatively complex. Beidou satellite signals are easily blocked by port facilities and equipment in berths, quay crane operation areas, and container yards. Some ports also have large indoor material warehouses that cannot receive Beidou satellite signals.

[0136] For each sub-area, determining whether the maximum signal strength of the signal strength interval corresponding to the sub-area is less than or equal to the preset signal strength; when it is determined that the maximum signal strength of the signal strength interval corresponding to the sub-area is less than or equal to the preset signal strength, determining the sub-area as the second sub-area;

[0152] Based on the business enablement layer corresponding to the intelligent service domain, according to the positioning requirements, at least one target service capability that meets the positioning requirements is selected from all candidate service capabilities.
