Positioning method, apparatus, and mobile terminal

An apparatus, comprising:

• a memory;
• and
• a processor coupled to the memory and configured to:
• determine an expected journey (L), wherein the L is an expected value of a distance traveled by the apparatus between two consecutive times of positioning the apparatus;
• obtain a speed value (v) of the apparatus;
• determine a positioning frequency at which to position the apparatus, wherein the positioning frequency is a frequency at which a position of the apparatus is determined between the two consecutive times, and wherein a deviation between an actual distance traveled by the apparatus between the two consecutive times and the L traveled by the apparatus between the two consecutive times based on the positioning frequency is less than a specified threshold;
• adjust a current positioning frequency to be the positioning frequency;
• and
• perform a positioning operation to determine one or more positions of the apparatus at one or more times according to the positioning frequency.

A mobile terminal, comprising:

• a memory;
• a processor connected to the memory;
• an input apparatus connected to the processor;
• and
• an output apparatus connected to the processor,
• wherein by invoking an operation instruction stored in the memory, the processor is configured to:
• determine an expected journey (L), wherein the L is an expected value of a distance traveled by the mobile terminal between two consecutive times of positioning the mobile terminal;
• obtain a speed value (v) of the mobile terminal;
• determine a positioning frequency at which to position the mobile terminal, wherein the positioning frequency is a frequency at which a position of the mobile terminal is determined between the two consecutive times, and wherein a deviation between an actual distance traveled by the mobile terminal between the two consecutive times and the L traveled by the mobile terminal between the two consecutive times based on the positioning frequency is less than a specified threshold;
• adjust a current positioning frequency to be the positioning frequency;
• and
• perform a positioning operation to determine one or more positions of the mobile terminal at one or more times according to the positioning frequency.
