From UMTS, the main function of the PDCP layer has been the header compression of IP packets – this is the reason why it is called the Packet Data Convergence Protocol. In LTE, the PDCP layer has evolved to support a security function; that is, integrity protection and ciphering .
Read moreWhat is the difference between ciphering and integrity protection in LTE?
Ciphering is needed when you want that only authorized people can ACCESS TO SEE the data. Integrity is when authorized people can ACCESS TO MODIFY the data .
Read moreWhat is LTE protocol stack?
The protocol stack functions consist of the Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC) . LTE is the latest generation of the 3GPP standards. The LTE standard specifies an IP-only network supporting data rates up to 150 Mbps.
Read moreWhat is RRC and PDCP?
PDCP stands for Packet Data Convergence Protocol . It is a layer of 5G NR radio protocol stack. It is placed top of the RLC Layer and below of the SDAP layer(for user plane) or RRC layer (for control plane) in the Radio Protocol Stack in 5G NR. Due to header compression functionality, it is called as convergence …
