Method and Apparatus for Data Interaction

An apparatus for data interaction, comprising:

• an obtaining unit, configured to obtain current required times of data interaction between valid applications in a background application mode and a network;
• a selecting unit, configured to select a minimum required time from the current required times as a target required time of data interaction;
• a timing unit, configured to required timestart timing and reset the target required time;
• a determining unit, configured to:
• when the target required time expires, obtain each valid application whose current required time of data interaction is between two consecutive target required times, and determine the valid application as a target application;
• and
• an interacting unit, configured to activate a packet data protocol PDP, establish a data link between the target application and the network, and return to the selecting unit after performing data interaction.
