The invention relates to communication technology, and in particular, to a method of establishing communication connection between a mobile device and a secure element as well as a mobile device for implementing the method. The method comprises the following steps: when the mobile device detects that there is a secure element which establishes a physical connection with it, the mobile device performs a secure authentication on the secure element; if the secure authentication passes, the mobile device determines whether there is configuration information inside it which is required for establishing the communication connection between the mobile device and the secure element; and if there is the required configuration information inside the mobile device, the mobile device uses the configuration information to establish the communication connection with the secure element; otherwise, the mobile device obtains required configuration information from the secure element to establish the communication connection with the secure element.
