KEY OBTAINING METHOD AND APPARATUS

Abstract: a terminal may send, to a first node, a first message indicating that the terminal is to access a network, so that the first node configures a key for the terminal and the network to be accessed by the terminal. in this way, authentication or authorization can be performed between the terminal and the network by using the configured key instead of a key in a sim card, so that the sim card and the network are unbound. therefore, if a user expects to switch the network, the user does not need to replace the sim card, thereby improving user experience.
