Network-assisted satellite navigation positioning method and terminal, and network-side equipment

摘要

A network-assisted satellite navigation positioning method, a terminal, and network-side equipment, which relate to the satellite navigation positioning field. In the network-assisted satellite navigation positioning method, the terminal transmits an auxiliary positioning information request to the network side, and the auxiliary positioning information request includes an instruction to provide ionosphere auxiliary information (A100). Receiving feedback ionosphere auxiliary information, performing corresponding ionospheric delay correction, thereby realizing a positioning operation (A200). In the network-assisted satellite positioning process by the above technical solution, the mobile communication network can transmit the ionosphere information having the target property to the terminal, thereby improving the positioning accuracy. At the same time, the technical solution saves resources and speeds up the terminal locking the valid information and finally positioning. The technical solution is not limited to the Hokuto satellite positioning scene, but may be applied to other satellite navigation positioning scenes. [Selection] Figure 2 (a)
