LTE Packet Data Convergence Protocol (PDCP) Overview

By agaur on October 6, 2012

Similar to UMTS technology, Packet Data Convergence Protocol (PDCP) is located above the RLC layer at UE as well as in eNB. However in LTE, all user data goes via the PDCP layer as ciphering is performed in PDCP.  The main functions of PDCP are IP header compression (UP), ciphering and integrity protection (Control Plane only). PDCP layer also carries RRC signaling messages as well so it is part of control plane as well.

LTE MAC Protocol

LTE Medium Access Control (MAC) is a layer 2 protocol and provides data transfer and radio resource allocation services to upper layers. It performs scheduling of the data according to priorities, and multiplexing data to physical layer transport blocks.  RRC  layer controls  configuration of MAC sublayer. In E-UTRA, there are two MAC entities, one in the UE and other one in the eNB.

IMS Centralized Services

3GPP initiated, IMS Centralized Services (ICS) paves the way for communication services that are based on IMS mechanisms. ICS enables IMS services for traditional circuit switched voice access. With ICS, user sessions are anchored in IMS network when user devices access via PS or CS access networks. UEs can be enhanced to support ICS capability otherwise UEs without ICS capability are also supported by ICS framework. 

What all new protocols 3GPP Long Term Evolution (LTE) technology brings in?

By agaur on September 1, 2012

With Release 8, 3GPP has introduced a whole new set of protocols as both radio access network and core network have evolved from the earlier 2G & 3G Networks. In LTE architecture, evolved core network includes Mobility Management Entity (MME), Serving Gateway  (SGW), Packet Data Network Gateway (PDN GW) where as evolved radio network has only E-UTRAN NodeB (eNB).
