Overview

SIST EN 301 349 V8.4.1:2005 defines the Radio Link Control/Medium Access Control (RLC/MAC) protocol at the Mobile Station (MS) - Base Station System (BSS) interface for the Global System for Mobile Communications (GSM) General Packet Radio Service (GPRS). This standard conforms with GSM 04.60 version 8.4.1 (Release 1999) and is published by the Slovenski inštitut za standardizacijo (SIST) as the national adoption of the EN series for digital cellular telecommunications systems.

The RLC/MAC protocol is essential for managing packet data communication over the air interface in GSM/GPRS networks. It outlines the procedures needed for reliable data transfer and efficient resource allocation between the mobile station and the network. The scope includes enhancements and clarifications relevant to measurement reporting, packet access procedures, and control message structure - ensuring interoperability and efficiency in packet-switched mobile networks.

Key Topics

The standard addresses a wide range of protocol elements crucial for robust and flexible GPRS operation at the radio interface. Key focus areas include:

• Layered Architecture: Defines RLC/MAC layer services and functions, including service primitives and the relationship with physical and logical layers.
• MAC Procedures: Specifies Medium Access Control for both idle and transfer modes, covering channel allocation, access grant, paging, and contention resolution.
• RLC Procedures: Details procedures and parameters for acknowledged and unacknowledged modes, peer-to-peer data block transfer, sequencing, and flow control.
• Temporary Block Flows (TBFs): Describes establishment, management, and release of uplink and downlink TBFs for single and multi-phase access methods.
• Measurement Reporting: Procedures for mobile-initiated and network-initiated measurement reports, including Network Controlled (NC) and Extended Measurement (EM) reporting.
• Power Control: Clarifies power control requirements during TBF establishment and ongoing data transfer.
• System Information Broadcast: Mechanisms for conveying system and cell-specific information via broadcast and control channels.
• Control Message Structure: Defines both uplink and downlink RLC/MAC control block formats and header construction, supporting GPRS and EDGE/EGPRS.
• Error and Exception Handling: Outlines abnormal case procedures, resource reconfiguration, and message acknowledgement mechanisms for reliable communication.

Applications

The RLC/MAC protocol standard is foundational in the deployment and operation of GSM/GPRS networks, directly enabling:

• Mobile Internet Access: Supports efficient mobile packet data services, fundamental for browsing, email, and real-time apps over GSM.
• M2M and IoT Communications: Enables reliable radio access for a wide range of cellular devices, including IoT sensors and M2M communication modules.
• Interoperability: Ensures standard-compliant mobile devices operate correctly with BSS equipment from various vendors in complex multi-vendor networks.
• Network Optimization: Facilitates flexible resource allocation, power management, and dynamic radio link adaptation-boosting overall spectrum efficiency.
• Feature Expansion: Supports enhancements such as EGPRS (EDGE), which provide higher speed packet data services within GSM networks.

Related Standards

Several closely associated standards provide the technical framework in which SIST EN 301 349 V8.4.1:2005 operates:

• EN 301 344: GSM Physical Layer on the radio interface.
• EN 301 347: GPRS Mobile Station to Serving GPRS Support Node (SGSN) interface.
• GSM 04.08 / EN 301 350: Mobile Radio Interface Layer 3 specification.
• GSM 05.08 / EN 301 345: Radio Subsystem Link Control.
• GSM 04.18: Mobile Station–Base Station System Layer 2 specification.

Adhering to these and SIST EN 301 349 ensures seamless integration and high reliability for packet radio services in GSM mobile networks.
