Method for dynamic configuration of APN and communication system

The invention provides a method for the dynamic configuration of APN and a communication system, the method is applied to user equipment comprising a wireless terminal equipment-corresponding terminal management module, which is provided with an APN configuration storage unit, the method comprises the steps: a server sends a short message for the configuration of APN to the wireless terminal equipment; upon the reception of the short message, the wireless terminal equipment analyzes the content of the short message and, if the content of the short message is determined to conform to predetermined specifications, APN configuration parameters are extracted from the short message and are written into the APN configuration storage unit. According to the invention, an operator has no need of returning APN to manufacturer for software upgrade when upgrading APB setting is required, thus APN change requirement can be completed independently.
