Abstract: Positioning method and apparatus provide two services: a first, common positioning service and a second, high-precision positioning service to an upper-layer application through permission control and an independent reporting channel design. For a common application, a positioning result can be reported with a first, common precision through a common reporting channel. For a high-precision application, a positioning result with a higher level of precision can be reported through a high-precision reporting channel. In this way, the channel for obtaining the positioning result by the common application is isolated from the channel for obtaining the positioning result by the high-precision application, thus improving output security of the high-precision positioning result and satisfying security requirements of different countries or regions.
