Abstract

A method for reading current position data from a remote portable electronic device through a signal switching network system is provided. The remote portable electronic device, after obtaining its own position data, can transmit the current position data through a signal transmission interface and a signal transmission network of the signal switching network system to a position database on a server. A portable electronic device at the request end can login to the server through the signal transmission network of the signal switching network system, and read the current position data of the specific remote portable electronic device from the position database of the server.
