Abstract: A communication method and an apparatus, used for solving the problem of data transmission timeliness being influenced by untimely establishment of a communication connection. A service processing unit and a wireless communication unit within a first communication apparatus both deploy a network protocol stack, and thereby before the service processing unit enters into an operational mode, the wireless communication unit may establish a transmission channel with a second communication apparatus on the basis of the deployed network protocol stack; after the service processing unit enters into the operational mode, the service processing unit, in combination with the deployed network protocol stack and by means of the transmission channel, performs data interaction with the second communication apparatus. Because the wireless communication unit opens a transmission channel before the service processing unit enters into the operational mode, once the service processing unit enters into the work mode, the transmission channel that has already been established can thereby be directly used by said service unit to perform data interaction with the second communication apparatus. Compared to a hole punching process being triggered after the service processing unit has entered into the operational mode, the present invention prevents time resource waste and ensures data transmission timeliness.
