Information acquisition method, information acquisition device and network device, terminal

Abstract

We provide an information acquisition method, an information acquisition device, a node device, and a terminal. [Solution] The method includes receiving a first request message transmitted from a terminal to request the acquisition of an accessible analysis identifier; acquiring the terminal's contracted analysis identifier and / or network-supported analysis identifier based on the first request message; determining the terminal's accessible analysis identifier based on the terminal's contracted analysis identifier and / or network-supported analysis identifier; and transmitting the accessible analysis identifier to the terminal.
