In addition, the Um interface is the air interface of GSM. The communication protocol on the Um interface has 5 layers, namely, the physical layer, MAC layer, LLC layer, SNDC layer and network layer from bottom to top. RLC / MAC is the wireless link control and media access control layer. The LLC layer is the logical link control layer. GTP is the tunnel technology used to transmit user data and signaling between GSN nodes in the GPRS network.
