SIST EN 301 349 V8.3.1:2004 is the Slovenian adoption of ETSI EN 301 349 Version 8.3.1 for the GSM General Packet Radio Service (GPRS) radio interface. It specifies the Radio Link Control/Medium Access Control (RLC/MAC) procedures at the Um interface between a Mobile Station (MS) and the Base Station System (BSS), including packet access, paging, resource allocation, block transfer and control-message handling. It is written for implementers, operators and test labs working with GPRS and Enhanced GPRS (EGPRS) radio behaviour.

What does SIST EN 301 349 V8.3.1:2004 specify?

SIST EN 301 349 V8.3.1:2004 covers the GPRS RLC/MAC layer used on Packet Data Channels (PDCHs) at the Um radio interface. It applies to Radio Link Control functions, Medium Access Control functions and Physical Link Control functions, and the text treats “GPRS” as including EGPRS unless stated otherwise.

The document is organized into clauses on:

• layered overview of the radio interface
• MAC procedures and paging
• packet idle and packet transfer modes
• RLC procedures in packet transfer mode
• RLC/MAC block structure
• message functional definitions and contents
• information element coding
• timers and counters

Annex	What it covers
A	Bibliography
B	RLC data block encoding examples
C	Message sequence diagrams
D	Fixed allocation timeslot assignment examples
E	Repeated fixed allocations
F	Countdown procedure examples
G	Erroneous protocol data examples
H	Document change history
I	EGPRS RLC window sizes

What are the key requirements of SIST EN 301 349 V8.3.1:2004?

Radio access and transfer modes

• Clause 5 defines the Temporary Block Flow (TBF) as the physical connection used for one-way transfer of LLC PDUs on PDCHs. In practice, this is the radio resource that carries packet data while a transfer is active.
• Clause 5.2.4 defines the supported medium access modes: Dynamic Allocation, Extended Dynamic Allocation and Fixed Allocation. The network must choose a mode that matches the MS multislot class, so capacity planning and device capability have to line up.
• Clause 5.4 separates packet idle mode from packet transfer mode. In packet idle mode the MS monitors paging channels; in packet transfer mode it has allocated radio resources and can send or receive packet data.

System information, paging and cell reselection

• Clauses 5.5.1.2 and 5.5.2.1 define how the MS and network handle PSI messages on PBCCH and SI messages on BCCH, including change-mark supervision and consistent message sets. This matters because the MS must keep cell information current before it can access the cell.
• Clauses 5.5.1.3 and 5.5.1.4 describe how the MS acquires system information when PBCCH is absent or changes. The document ties access permission to successful reception of the required system information.
• Clause 5.5.1.6 defines page mode handling on PCCCH. The page mode tells the MS whether normal paging, extended paging or paging reorganization applies, which affects how much of the paging channel it must monitor.

RLC/MAC block handling and control

• Clauses 8, 9 and 10 define RLC data transfer, acknowledged and unacknowledged operation, and the fields inside RLC/MAC blocks such as TFI, USF, BSN and TLLI. These definitions control how blocks are identified, scheduled and acknowledged.
• Clause 11 defines message handling, including error detection, message classification and the control messages used for access, assignment, measurement reporting, release and reconfiguration. In practice, implementers use this to build interoperable signalling.
• Clause 12 defines the information elements used in assignments and system information, including Frequency Parameters, GPRS Mobile Allocation, Packet Timing Advance and related identifiers. Clause 13 defines the timers and counters that drive timeouts and retry behaviour.

What terms does SIST EN 301 349 V8.3.1:2004 define?

• Temporary Block Flow (TBF) - the temporary physical connection that carries LLC PDUs on packet data channels.
• Temporary Flow Identity (TFI) - the identifier the network assigns to a TBF to distinguish it from other active flows.
• Uplink State Flag (USF) - the downlink header value that tells an MS when it may transmit on the uplink.
• Packet idle mode - the state where the MS has no TBF and listens for paging on PCCCH or CCCH.
• Packet transfer mode - the state where the MS has radio resources for point-to-point packet transfer.
• GPRS TBF mode - a TBF that does not use EGPRS enhancements such as 8PSK or Incremental Redundancy.
• EGPRS TBF mode - a TBF that uses EGPRS enhancements, including 8PSK and Incremental Redundancy.

Who uses SIST EN 301 349 V8.3.1:2004?

SIST EN 301 349 V8.3.1:2004 is used by MS and BSS implementers, radio protocol designers, network operators, and conformance and interoperability test labs. It is relevant when designing packet access, paging, channel assignment, measurement reporting, and RLC/MAC block exchange for GSM packet data networks.

What changed in SIST EN 301 349 V8.3.1:2004 from the previous edition?

This version is an upgrade to Release 1998 and includes change requests from SMG#30, SMG#30bis and SMG#31.

Which standards are used with SIST EN 301 349 V8.3.1:2004?

The document references companion GSM parts for definitions, radio architecture, and procedures, including:

• GSM01.04 for abbreviations and acronyms
• GSM02.60 for the GPRS stage 1 service description
• GSM03.03 for numbering, addressing and identification
• GSM03.13 for discontinuous reception (DRX)
• GSM03.64 for the overall GPRS radio interface description
• GSM04.02, GSM04.03, GSM04.04, GSM04.05, GSM04.07 and GSM04.08 for the radio interface configuration, channel structures, layer 1, data link aspects and CCCH procedures
• GSM04.64 for Logical Link Control (LLC)
• GSM05.02, GSM05.03, GSM05.08 and GSM05.10 for multiplexing, coding, radio link control and synchronization
• GSM11.10 and GSM11.21 for MS and BSS conformance-related context

What does the SIST EN 301 349 V8.3.1:2004 document contain?

The document contains procedural descriptions, state-dependent behaviour, control-message formats, information-element coding and timer/counter rules for GPRS RLC/MAC operation. It also includes informative annexes with worked examples for block encoding, fixed allocation, countdown and protocol-error handling. Annex C adds message sequence diagrams, and Annex I gives EGPRS RLC window sizes for reference.
