Optionally, L2 comprises a medium access control (Media Access Control, MAC) functional entity; l3 includes a functional entity for processing User data, such as a User Plane (UP) functional entity, denoted as L3UP, capable of processing and transmitting data packets transmitted by a User; and also includes a functional entity for processing Control data, such as a Control Plane (CP) functional entity, for performing a radio resource Control function.
The MAC functional entity of the L2 has the functions of bearing upper-layer service data and combining the channel characteristics of a lower-layer air interface to form QoS indexes and operations which take the air interface and the service characteristics into consideration. In addition, the UP function entity of L3 of the AS layer has a transmission function of the IP packet for the first time or more. With the introduction of the UP functional entity of L3, the existing data processing functions of L2 need to be redefined.
