The embodiment of the invention provides a communication connection method and a data card. Communication connection method may include obtaining data flow from the client's data card; if the card and the data communication network without communication connection, the data card to establish a connection with the communication between the communication network; the data card will be the data flow through the communication connection is transmitted to the communication network. Statistics and start standby time; if the standby time threshold is preset in the data card no longer received from the client data flow, the data communication between the card and disconnect the communication network connection; if the preset threshold in the standby time, the data from the client receiving card to the data flow, the data card to the standby time statistics. The embodiment of the invention realizes that the data card can automatically establish and disconnect the communication connection with the communication network according to the data flow from the client, thereby improving the flexibility and the efficiency of the data card.
