Abstract

The invention discloses a terminal-to-terminal positioning method and system. The method comprises the following steps: a first terminal sends a positioning request message to a first positioning server, wherein the positioning request message carries the identity of a second terminal; and the first positioning server acquires the position information of the second terminal according to the identity. According to the technical scheme provided by the invention, terminal-to-terminal positioning can be realized, and the positioning requirements of users can be satisfied.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a terminal-to-terminal positioning method and system. Background technique [0002] The positioning service is the most attractive service in the mobile value-added service, and it is also one of the most complicated services in every link of the industry chain. With the popularization and development of positioning services, people put forward higher and higher demands on positioning services. In performing Security User Plane Location (SUPL for short) positioning services, traditional positioning terminals usually initiate their own positioning initiatively, or some services on the network side require the location information of the user and request the location information of the terminal . Combine the following figure 1 The principle of the existing SUPL positioning technology is described. [0003] like figure 1 As shown, the terminal supporting SUPL (SUPL Enable Ter...
