Abstract
The present invention relates to a communication system. The communication system includes a handheld communication device, a primary communication module, and a secondary communication apparatus. The primary communication module is configured for communicating with the secondary communication apparatus within a predetermined coverage area. When receiving a short message signal, the handheld communication device broadcasts a search signal. The secondary communication apparatus detects the search signal and sends a response signal to the handheld communication device according to the user's operations. The handheld communication device detects whether the response signal is received and processes accordingly. The present invention also provides a method of applying a security function for short messaging adapted for supporting the aforementioned communication system.
