Terminal positioning method and network device

A network device, comprising:

• a memory configured to store instructions;
• and
• a processor coupled to the memory, the instructions causing the processor to be configured to:
• obtain radio signal sampling information of a first terminal at a current moment and a predictive model of a target region, the first terminal being any terminal in the target region, the target region being a preset geographic region, the predictive model being determined based on a plurality of data pairs of at least two historical terminals in the target region, the data pairs of any historical terminal of the at least two historical terminals being obtained based on radio signal sampling information of a historical terminal at a plurality of first historical moments and position information of the historical terminal at a plurality of second historical moments, the radio signal sampling information of the historical terminal at the first historical moments being obtained based on a first frequency, the position information of the historical terminal at the second historical moments being obtained based on a second frequency, the first frequency being less than the second frequency, each data pair of the data pairs comprising one piece of radio signal sampling information of the radio signal sampling information of the historical terminal at the first historical moments and position information, and the position information in each data pair corresponding to the one piece of radio signal sampling information of the radio signal sampling information of the historical terminal at the first historical moments;
• and
• obtain position information of the first terminal at the current moment by prediction based on the radio signal sampling information of the first terminal at the current moment and the predictive model of the target region.

A network device, comprising:

• a memory configured to store computer program instructions;
• and
• a processor coupled to the memory, the computer program instructions causing the processor to be configured to:
• obtain radio signal sampling information of a historical terminal at a plurality of first historical moments and position information of the historical terminal at a plurality of second historical moments, the radio signal sampling information of the historical terminal at the first historical moments being obtained based on a first frequency, the position information of the historical terminal at the second historical moments being obtained based on a second frequency, and the first frequency being less than the second frequency;
• and
• obtain a plurality of data pairs of the historical terminal based on the radio signal sampling information of the historical terminal at the first historical moments and the position information of the historical terminal at the second historical moments, each data pair of the data pairs comprising one piece of radio signal sampling information of the radio signal sampling information of the historical terminal at the first historical moments and position information, and the position information in each data pair corresponding to one piece of radio signal sampling information of the radio signal sampling information of the historical terminal at the first historical moments.
