Abstract: A radio access network includes a transport network layer; a radio network layer having a layer 2 network for communicating between entities within the radio network layer by exchanging datagrams having a predetermined format used only within the radio network layer. Accordingly, the present invention provides for a true decoupling at layer 2 between the radio network layer and the transport network layer. Addressing at layer 2 can enable both connectionless and connection oriented using an overlay connectivity model. Layer 2 in the radio network layer is implemented as an Ethernet network.
