PURPOSE: A virtual character calling method using a callback SMS is provided to maintain a character call state on a standby screen when a text message is transceived, and to automatically convert into a network always-on state if a user wants to send a predetermined character, thereby realizing a virtual network always-on system. CONSTITUTION: A caller writes a text message, and selects a predetermined key(S201). A receiver's terminal receives calling information, and performs a character call on an intelligent SMS platform(S203). An SMS control code is transmitted to the SMS platform, and is sent to an SMS service logic for the character call(S205). The SMS service logic receives TID information to decide whether a current short message mode is a character call mode(S207,S209). If not, the logic writes a predetermined text message(S217), and carries out another PDSN connection(S219). The receiver sends the text message to the caller's terminal(S221). |
