Positioning methods, positioning device, and system

A positioning device comprising:

• a receiver arranged to receive a signal from a mobile device;
• and
• a processor;
• and
• a computer-readable storage medium coupled to the processor and storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
• determine a positioning information of the mobile device based on the received signal;
• provide the determined positioning information of the mobile device to a positioning engine;
• obtain an offset between the determined positioning information and an estimated positioning information determined by the positioning engine, wherein the estimated positioning information is based on an estimated position of the mobile device and a known position of the positioning device, and wherein the estimated position of the mobile device is based on the determined positioning information of the mobile device;
• and
• train a positioning algorithm of the positioning device based on the obtained offset.

A positioning method, performed by a system comprising a positioning device and a positioning engine, the positioning method comprising:

• receiving, by the positioning device, a signal from a mobile device;
• determining, by the positioning device, a positioning information of the mobile device based on the received signal;
• providing, by the positioning device, the determined positioning information of the mobile device to the positioning engine;
• determining, by the positioning engine, an estimated position of the mobile device based on the determined positioning information of the mobile device sent by the positioning device and based on further determined positioning information of the mobile device sent to the positioning engine by at least two further positioning devices;
• determining, by the positioning engine, an estimated positioning information of the mobile device based on the estimated position of the mobile device and a known position of the positioning device;
• obtaining, by the positioning device, an offset between the determined positioning information and the estimated positioning information determined by the positioning engine;
• and
• training, by the positioning device, a positioning algorithm of the positioning device based on the obtained offset.

A system comprising:

• a positioning device comprising
• a receiver arranged to receive a signal from a mobile device, and
• a processor, and
• a computer-readable storage medium coupled to the processor and storing instructions that, when executed by the processor, cause the processor to perform operations comprising
• determining a positioning information of the mobile device based on the received signal;
• providing the determined positioning information of the mobile device to a positioning engine;
• obtaining an offset between the determined positioning information and an estimated positioning information determined by the positioning engine;
• and
• the positioning engine, wherein the positioning engine is arranged to determine the estimated positioning information of the mobile device based on an estimated position of the mobile device and a known position of the positioning device, and based on the determined positioning information of the mobile device sent by the positioning device and based on further determined positioning information of the mobile device sent to the positioning engine by at least two further positioning devices.

A non-transitory computer-readable storage medium storing instructions that, when executed by at least one processor of a positioning device, cause the at least one processor to perform operations comprising:

• determine a positioning information of a mobile device based on a received signal from the mobile device;
• provide the determined positioning information of the mobile device to a positioning engine;
• obtain an offset between the determined positioning information and an estimated positioning information determined by the positioning engine, wherein the estimated positioning information is based on an estimated position of the mobile device and a known position of the positioning device, and wherein the estimated position of the mobile device is based on the determined positioning information of the mobile device;
• and
• train a positioning algorithm of the positioning device based on the obtained offset.
