Generic positioning protocol

摘要

In an aspect, a generic positioning protocol (GPP) may be used to support satellite-based positioning methods and terrestrial-based positioning methods for different access types. A terminal may exchange a first GPP message with first information for a positioning method and an access type supported by GPP. The terminal may exchange a second GPP message with second information for the positioning method and the access type. Each GPP message may include at least one position element, and each position element may be for a specific positioning method. The terminal may obtain a position estimate for itself based on the second information. In another aspect, positioning may be performed based on measurements for cells of different wireless access types. In yet another aspect, received transmission times may be transformed to converted times based on common timing, which may be applicable for multiple wireless access types.

1. A method of performing positioning, comprising:
exchanging a first generic positioning protocol (GPP) message comprising first information for a first positioning method and a first wireless access type supported by a GPP, wherein the GPP supports multiple positioning methods and at least three wireless access types; exchanging a second GPP message comprising second information for the first positioning method and the first wireless access type; and obtaining a position estimate for a terminal based on the second information.
