A Network-Aided Method, Terminal and Network Side Device for Satellite Navigation and Positioning

摘要

Disclosed are a network-aided method, user equipment, and network side device for satellite navigation and positioning, related to the field of satellite navigation and positioning. The network-aided satellite navigation and positioning method includes: a user equipment sending a network side an auxiliary positioning information request containing an indication of providing ionospheric auxiliary information (A100); the user equipment receiving ionospheric auxiliary information fed back from the network side, and correspondingly performing the ionospheric time delay correction to carry out a positioning operation (A200). The abovementioned technical solution allows a mobile communication network to transmit targeted ionospheric information to the user equipment in a network-aided satellite positioning process, thereby improving the positioning precision. Meanwhile, the abovementioned technical solution saves resources, speeds up the user equipment to lock effective information and finally achieves positioning.
