Measurement compensation method, apparatus, server, and system in base station positioning

A measurement compensation apparatus in a positioning server for base station positioning, comprising:

• a receiving module, configured to receive an RSTD measurement value between different base stations that is reported by a mobile terminal;
• an acquiring module, configured to acquire an RSTD measurement compensation value corresponding to a positioning aid device that has a coverage range, wherein the positioning aid device is pre-deployed in a fixed position, the mobile terminal is positioned in a range covered by the positioning aid device corresponding to the fixed position, the RSTD measurement compensation value is used to compensate RSTD measurement within the range, and accuracy of the RSTD measurement compensation value depends on a size of the range covered by the positioning aid device;
• and
• a compensating module, configured to compensate, according to the RSTD measurement compensation value acquired by the acquiring module, the RSTD measurement value received by the receiving module to obtain an RSTD compensation result.

A positioning server, comprising:

• a transceiver, configured to receive an RSTD measurement value between different base stations that is reported by a mobile terminal;
• and
• a processor, configured to:
• acquire an RSTD measurement compensation value corresponding to a positioning aid device that has a coverage range, wherein the positioning aid device is pre-deployed in a fixed position, the mobile terminal is positioned in a range covered by the positioning aid device corresponding to the fixed position, the RSTD measurement compensation value is used to compensate RSTD measurement within the range, and accuracy of the RSTD measurement compensation value depends on a size of the range covered by the positioning aid device;
• and compensate the RSTD measurement value according to the RSTD measurement compensation value to obtain an RSTD compensation result.

A base station positioning system, comprising:

• a positioning server and a positioning aid device that has a coverage range;
• wherein
• the positioning aid device is pre-deployed in a fixed position, and is configured to report an auxiliary RSTD measurement value between different base stations;
• and
• the positioning server is configured to:
• receive an RSTD measurement value between the different base stations that is reported by a mobile terminal, wherein the mobile terminal is positioned in a range covered by the positioning aid device corresponding to the fixed position;
• calculate a difference between the auxiliary RSTD measurement value and an RSTD standard value between the different base stations of the positioning aid device, and take the difference as an RSTD measurement compensation value corresponding to the positioning aid device, wherein the RSTD measurement compensation value is used to compensate RSTD measurement within the range, and accuracy of the RSTD measurement compensation value depends on a size of the range covered by the positioning aid device;
• and
• compensate the RSTD measurement value according to the RSTD measurement compensation value to obtain an RSTD compensation result.
