SIST EN 301 349 V8.4.1:2005 is the Slovenian adoption of EN 301 349 Version 8.4.1 for the GSM General Packet Radio Service (GPRS) radio interface. It specifies the Radio Link Control/Medium Access Control (RLC/MAC) protocol on the Mobile Station (MS) - Base Station System (BSS) interface, so it is the document for implementing and testing packet access, paging, measurement reporting, and data transfer on packet data channels.

What does SIST EN 301 349 V8.4.1:2005 specify?

SIST EN 301 349 V8.4.1:2005 specifies the procedures used at the radio interface, at Reference Point Um, for the GPRS MAC/RLC layer. In practice, it tells the MS and network how to share packet radio resources, how to establish and release Temporary Block Flows (TBFs), how to move between packet idle and packet transfer mode, and how to format the related control and data blocks.

The main body runs from clauses 1 to 13 and covers scope, references, definitions, the layered overview of the radio interface, MAC procedures, paging, packet transfer procedures, RLC procedures, block structure, control message definitions, information element coding, and timers and counters.

What are the key requirements of SIST EN 301 349 V8.4.1:2005?

SIST EN 301 349 V8.4.1:2005 defines how a GPRS MS and network must request, assign, use, and release packet radio resources. The most important requirements are the access modes, the idle/transfer behavior, the measurement and paging procedures, the RLC transfer rules, and the message and block formats that make interoperability possible.

Access modes, packet idle mode, and packet transfer mode

Clause 5.2 states that Dynamic Allocation and Fixed Allocation shall be supported in all MSs, and that Extended Dynamic Allocation is mandatory for multislot classes 22, 24, 25, and 27. For a buyer or integrator, that means the device’s declared multislot capability directly affects which packet scheduling modes it must handle.

Clauses 5.3 and 5.4 distinguish packet idle mode from packet transfer mode. In packet idle mode there is no TBF and the MS listens for paging on PCCCH or, if that is absent, on CCCH; in packet transfer mode the MS uses one or more PDCHs for unidirectional LLC PDU transfer. In practice, this is the core state change that drives resource use, battery behavior, and uplink/downlink traffic handling.

Clause 7.1.1 limits network access to authorised access classes. That matters when access has to be controlled during congestion, special access conditions, or class-based barring.

System information, paging, and measurements

Clauses 5.5.1 and 5.5.2 describe how the MS acquires system information on PBCCH and BCCH and how the network broadcasts it. The MS must follow PSI and SI change information, and the network may repeat PSI messages on PACCH when the MS cannot receive the normal broadcast channels for a long period. This keeps the MS aligned with the current cell configuration during packet transfer.

Clauses 5.6, 7.3, 8.3, and 8.5 define Network Control (NC) measurement reporting and Extended measurement (EM) reporting. The MS uses the relevant timers, performs the requested measurements, and sends the defined report messages. For implementation, this means measurement reporting is timer-driven and depends on whether the MS is in packet idle mode or packet transfer mode.

Clauses 6 and 8.4 define paging and network-controlled cell reselection. The network can page an MS for RR connection establishment or for downlink packet transfer, and it can order cell changes through the packet cell change order procedure. In practice, this is how the network reaches an idle MS or moves a transfer to a new cell.

TBF establishment and data transfer

Clauses 7.1 and 7.2 define mobile-originated and network-initiated TBF establishment, including one phase access, two phase access, contention resolution, and timing advance handling. These procedures tell the MS how to ask for packet resources and tell the network how to allocate them back.

Clause 8.1 governs uplink and downlink RLC data block transfer for Dynamic Allocation, Extended Dynamic Allocation, and Fixed Allocation. The network signals the MAC mode in the assignment procedures, and resource reallocation cannot change the RLC mode or TBF mode of an established TBF. If the mode must change, the current TBF has to be released and a new one established.

Clause 8.2 defines PACKET PDCH RELEASE, which tells the MS that one or more timeslots are no longer available. Clause 8.6 defines PACKET CONTROL ACKNOWLEDGEMENT, which must be sent in the uplink block indicated by the valid RRBP field. This is important for precise scheduling and for confirming control signaling at the expected time.

RLC procedures, block structure, and error handling

Clause 9 defines acknowledged and unacknowledged RLC operation, segmentation and reassembly of LLC PDUs, and the state variables and window logic that govern retransmission. It also includes EGPRS-specific behavior, including mandatory Type II hybrid ARQ in EGPRS MS receivers and the required joint decoding combinations. In practice, this is where reliability, retransmission, and buffering rules are set.

Clause 10 defines the RLC/MAC block structures and header fields, including USF, TFI, BSN, FBI, TI, RRBP, CV, RSB, and PFI. These are the bits that implementers must encode and decode correctly for every block sent on PDCH.

Clauses 11, 12, and 13 define the message contents, information element coding, and timers and counters. Clause 11 also sets mandatory handling for unknown or syntactically incorrect protocol data, so receivers must classify errors in a defined order rather than handling them ad hoc.

What terms does SIST EN 301 349 V8.4.1:2005 define?

SIST EN 301 349 V8.4.1:2005 defines the vocabulary used by the protocol and gives the terms that matter most for implementation.

• Temporary Block Flow (TBF) - a temporary radio link used for unidirectional transfer of LLC PDUs between the MS and the network.
• Packet Data Channel (PDCH) - a packet data physical channel used to carry RLC/MAC blocks.
• Packet Broadcast Control Channel (PBCCH) - the broadcast channel used for packet system information when present in the cell.
• Packet Common Control Channel (PCCCH) - the shared control channel used for paging, access, and assignment when present.
• Uplink State Flag (USF) - a field on PDCHs that lets the network multiplex uplink radio blocks from different MSs.
• Enhanced GPRS (EGPRS) - the GPRS enhancement that uses 8PSK modulation and Incremental Redundancy to increase data rate.
• Temporary Flow Identity (TFI) - the identifier used to identify a TBF in the block headers and related procedures.

Who uses SIST EN 301 349 V8.4.1:2005?

SIST EN 301 349 V8.4.1:2005 is used by engineers who design and implement GPRS and EGPRS mobile stations, base station systems, and packet control procedures. It is also used by test labs and protocol conformance teams because it defines the procedures, timers, message formats, and error handling rules that interoperability testing depends on.

Quality managers, network operators, and buyers use it to check whether equipment supports the required access modes, measurement reporting, paging, and TBF behavior. That makes it relevant wherever radio packet interoperability and feature support have to be verified against a common GSM GPRS protocol description.

What changed in SIST EN 301 349 V8.4.1:2005 from the previous edition?

SIST EN 301 349 V8.4.1:2005 is the Slovenian standard identical with EN 301 349 Version 8.4.1.

Which standards are used with SIST EN 301 349 V8.4.1:2005?

SIST EN 301 349 V8.4.1:2005 relies on a set of GSM companion specifications for the radio interface, control procedures, measurements, and coding.

• GSM 01.04 and GSM 02.60 - provide the abbreviations used in the document.
• GSM 02.11 - defines authorised access classes and special access classes.
• GSM 03.13 - covers Discontinuous Reception (DRX), which affects paging behavior.
• GSM 04.02 - defines the Um reference point used by the scope.
• GSM 04.07 - defines service access points and service primitives.
• GSM 04.08 - provides CCCH procedures and related control-message handling.
• GSM 04.64 - defines the Logical Link Control (LLC) layer whose PDUs are carried by RLC/MAC.
• GSM 05.02 - defines multiplexing and multiple access on the radio path.
• GSM 05.03 - defines the channel coding schemes used for RLC/MAC blocks.
• GSM 05.08 - defines measurement reporting and cell reselection behavior.
• GSM 05.05 and GSM 05.09 - are referenced for EGPRS receiver performance requirements.

What does the SIST EN 301 349 V8.4.1:2005 document contain?
