WebPDCP fundamentally provides a compression service to higher layer data, which may be control plane or user plane (IP) traffic. When the LTE variant of PDCP compresses data, a separate standard termed ROHC (Robust Header Compression) is utilized (UMTS PDCP can use ROHC and an earlier standard termed IP Header Compression). Moreover, the LTE ... WebTransfer of data (user plane or control plane) Maintenance of PDCP SNs. Header …

WHAT IS THE PURPOSE OF THE PDCP LAYER? – Tech Trained

WebWHAT IS THE PURPOSE OF THE PDCP LAYER? In order to answer this question, take a look at the picture below. I have shown PDCP protocol both in Control and User plane protocol stack. Supports Robust Header Compression (ROHC) and decompression of user plane data. PDCP supports ciphering of user plane data and control plane data (NAS signaling). WebPDCP provides following services to the upper layers. • Transfer of user plane data and control plane data • Header compression/decompression using ROHC • Ciphering/Deciphering • Integrity protection PDCP expects following services supported from lower layers. • Acknowledged data transfer service • Unacknowledges data transfer service movies on today in perth

Web24 Oct 2013 · One of the main functions of the PDCP header compression is using Header Compression (ROHC) robust protocol defined by IETF (Internet Engineering Task Force) . In LTE, header compression is very important because there is no support for transport of voice circuit-switched (CS) domain. Thus in order to provide voice services (PS ) domain … WebPDCP layer performs following operation in the downlink and uplink. In downlink direction, it adds PDCP header to incoming data and forward it to RLC layer. In uplink direction, it removes PDCP header from incoming packet and forwards it to the IP layer. Following are the functions performed by PDCP layer.
