Abstract
Embodiments provide a location information obtaining method and a device, and relates to the communications field. The method includes: obtaining, by a network device, location information of a reference point and location information of first user equipment; determining, by the network device, relative location information of the first user equipment relative to the reference point; and sending, by the network device, the location information of the reference point and the relative location information of the first user equipment relative to the reference point.
Claims15
A method, comprising:
- obtaining, by a network device, location information of a reference point and location information of first user equipment;
- determining, by the network device, relative location information of the first user equipment relative to the reference point, wherein the relative location information comprises:
- a granularity of relative longitude location information and a transmission value of the relative longitude location information, or a granularity of relative latitude location information and a transmission value of the relative latitude location information, or a granularity of relative altitude location information and a transmission value of the relative altitude location information, wherein the relative longitude location information is equal to a product of the granularity of the relative longitude location information and the transmission value of the relative longitude location information, the relative latitude location information is equal to a product of the granularity of the relative latitude location information and the transmission value of the relative latitude location information, and the relative altitude location information is equal to a product of the granularity of the relative altitude location information and the transmission value of the relative altitude location information;
- and
- sending, by the network device to a second user equipment, the location information of the reference point and the relative location information of the first user equipment relative to the reference point.
