POSITIONING METHOD BASED ON RELIABILITY AND APPARATUS THEREOF

摘要

According to a positioning method of estimating a position of a terminal by being connected with a plurality of positioning, in the state in which a first reference position is calculated based on absolute coordinate positional information provided from one positioning resource, when a second reference position based on new absolute coordinate positional information from the positioning resource and reliability of the second reference position are calculated, an update of an reference position for user position estimation is optionally performed depending on whether the reliability of the second reference position satisfies a preset reference position update reference.

1. A positioning method of estimating a position of a terminal by being connected with a plurality of positioning resources, comprising:
estimating, by a positioning apparatus, a position of a user and calculating reliability of the estimated position of the user for the estimated position of the user, based on a first reference position depending on a first absolute coordinate position received from a positioning resource; calculating, by the positioning apparatus, a second reference position and reliability of the second reference position, based on a second absolute coordinate position received from the positioning resource; determining, by the positioning apparatus, whether the reliability of the second reference position satisfies a preset reference position update reference; updating, by the positioning apparatus, an reference position for user position estimation from the first reference position to the second reference position when the reliability of the second reference position satisfies the reference position update reference; and newly estimating, by the positioning apparatus, the position of the user based on the updated second reference position and calculating reliability of the estimated position of the user for the estimated position of the user.
