The user of the services provided by SNDCP is a packet data protocol (PDP) at the mobile Station (MS) or the Relay at the Serving GPRS Support Node (SGSN). Additionally, a control entity, e.g., AT command interpreter, may be an SNDCP user. SNDCP uses the services provided by the Logical Link Control (LLC) layer and the Session Management (SM) sub-layer. The main functions of SNDCP are: -Multiplexing of several PDPs. -Compression / decompression of user data. -Compression / decompression of protocol control information. -Segmentation of a network protocol data unit (N-PDU) into Logical Link Control Protocol Data Units (LL-PDUs) and re-assembly of LL-PDUs into a N-PDU. GSM 04.65 is applicable to GPRS MS and SGSN.
