What is user plane in LTE?
At user plane side, the application creates data packets that are processed by protocols such as TCP, UDP and IP, while in the control plane, the radio resource control (RRC) protocol writes the signalling messages that are exchanged between the base station and the mobile.
What is user plane protocol?
The User Plane, also called the Data Plane, carries the network user traffic. The user plane protocol stack between the e-Node B, and UE consists of the following sub-layers: PDCP (Packet Data Convergence Protocol), RLC (radio Link Control), and Medium Access Control (MAC).
How many layers does a LTE protocol suit have?
A simple way to understand telecom protocol stacks is to divide them in three different layers: the physical layer, the data link layer, and the network layer. These layers are implemented differently in each wireless protocol.
What is L1 L2 L3 in LTE?
LTE UE Stack is a key software element of LTE/LTE-A mobile terminal modems. It provides a complete implementation of UE L1 (PHY), L2 and L3 according to 3GPP Release 8, with elements of Release 9 and 10. It consists of highly modular shared libraries implementing logically divided subsets of LTE UE functionalities.
What is a user plane function?
The User Plane Function (UPF) is a fundamental component of a 3GPP 5G core infrastructure system architecture. Deployed within a dynamic cloud native compute infrastructure, the User Plane Function delivers the packet processing foundation for Service Based Architectures (SBAs).
What is control and user plane separation?
Control-/User Plane Separation (CUPS) [1] in mobile networks refer to the complete separation between control plane functions (which take care of the user connection management, as well as defining QoS policies, performing user authentication, etc.) and user plane functions (which deal with data traffic forwarding).
What is PSA UPF?
PDU Session Anchor. PSA is the term given to the UPF (User Plane Function) which terminates the N6 interface of a PDU session within a 5G core network.
What is Edge UPF?
5G UPF: THE KEY ENABLER OF THE NEW 5G EDGE This provides the flexibility to deliver user plane functionality at the edge as well as the network core. It also enables the application-specific, end-to-end assembly of connectivity and computing resources across a shared, multi-tenant 5G infrastructure (network slicing).
What is the layer of protocol stack?
A protocol stack is a prescribed hierarchy of software layers, starting from the application layer at the top (the source of the data being sent) to the data link layer at the bottom (transmitting the bits on the wire).
Can stack layers?
CAN protocol is based on the famous ISO- OSI reference model. There are seven layers through which every data packet passes, before it is transmitted or received. This 7-layered structure is industry-accepted and widely adopted approach used in communication protocols.
What are the different types of LTE protocol stack?
In LTE, depending upon User plane or Control Plane, the protocol stack has been divided into 2 different types. 1. LTE User Plane Protocol Stack 2. LTE Control Plane Protocol Stack
What is the user control plane in LTE?
The user plane LTE protocol stack consists of upper layers, NAS, PDCP, RLC, MAC, PHY and RF. The functions of each are outlined below: The modules are depicted in the figure on right side. NAS: In the uplink it does packet filtering.
What is the radio protocol architecture for LTE?
The radio protocol architecture for LTE can be separated into control plane architecture and user plane architecture as shown below: At user plane side, the application creates data packets that are processed by protocols such as TCP, UDP and IP, while in the control plane, the radio resource control (RRC)…
Which is part of the user plane protocol stack?
In both cases, the information is processed by the packet data convergence protocol (PDCP), the radio link control (RLC) protocol and the medium access control (MAC) protocol, before being passed to the physical layer for transmission. The user plane protocol stack between the e-Node B and UE consists of the following sub-layers:
