Lte User Plane Protocol Stack Pdf The document outlines the protocol stacks used in lte radio access, between the enodeb and sgw over the s1 u interface, and between the sgw and pgw over the s5 interface. The packet data convergence protocol (pdcp) layer [1]: this layer processes radio resource control (rrc) messages in the control plane and internet protocol (ip) packets in the user plane.
Lte Ue Protocol Stack Lte Ue User Plane Control Plane Rrc States This whitepaper presents an overview of the protocol stack for lte with the intent to describe where important functions reside along with the implications of such architectural design. The document describes the lte protocol stack, which contains a user plane and control plane. it divides the protocol stack into layers for the radio network and transport network. Let's have a close look at all the layers available in e utran protocol stack which we have seen in previous chapter. below is a more ellaborated diagram of e utran protocol stack:. It is split into two interfaces, one for the control plane and the other for the user plane. the protocol structure for the s1 and the functionality provided over s1 are discussed in more detail below.

It is split into two interfaces, one for the control plane and the other for the user plane. the protocol structure for the s1 and the functionality provided over s1 are discussed in more detail below. The teid in the gtp u header is used to de multiplex traffic incoming from remote tunnel endpoints so that it is delivered to the user plane entities in a way that allows multiplexing of different users, different packet protocols and different qos levels. Figure 2 shows the protocol stacks for the user plane, where pdcp, rlc, mac, and phy sublayers (terminated at the enb on the network side) perform functions like header compression, ciphering, scheduling, arq, and harq. Based on the research of the protocol stack data processing, the software architecture of the user plane and data transmission submodules are designed in this paper. The figures below diagram the key protocol stacks on uu, s1, and x2 interfaces for both c plane and u plane messaging. figure 1 : c plane protocol stack: uu (ue enb) and s1 c (enb mme) figure 2 : c plane protocol stack: x2 c (enb enb) figure 3 : u plane protocol stack: uu (ue enb) and s1 u (enb s gw) figure 4 : u plane protocol stack: x2 u (enb.
