This ETSI TS provides the overall description for lower-layer functions of the General Packet Radio Service (GPRS) radio interface (Um).
The overall description provides the following information:
- The services offered to higher-layer functions,
- The distribution of required functions into functional groups,
- A definition of the capabilities of each functional group and their possible distribution in the network equipment,
- Service primitives for each functional group, including a detailed description of what services and information flows are to be provided, and
- A model of operation for information flows within and between the functions.
This specification is applicable to the following GPRS Um functional layers:
- Radio Link Control functions,
- Medium Access Control functions, and
- Physical Link Control functions.
The overall GPRS logical architecture and the GPRS functional layers above the Radio Link Control and Medium Access Control layer are described in GSM 03.60 [2].This document describes the information transfer and control functions to be used across the radio (Um) interface for communication between the MS and the Network. Functions specific to other interfaces are described in GSM 03.60 [2].
