The GSM specifications are normative when used to describe the functionality of interfaces, but the stacks and the subdivision of protocol layers does not imply or restrict any implementation.</Section> <Section>The protocol stack for GPRS consists of several entities. Each entity has one ore more service access points, over which the entity provides a service for the upper entity.</Section> <Section>Figure 1-1: Architecture of the GSM/GPRS protocol stack</Section> <Section>The information units passed via the SAPs are called primitives and consists of an operation code and several parameters. See the Users Guide for details.</Section> <Section>The entities of the GPRS protocol stack are:</Section> <Section>1.1 GRR (RLC/MAC) - Radio Link Control/Medium Access Control</Section> <Section>This layer contains two functions: The Radio Link Control function provides a radio-solution-dependent reliable link. The Medium Access Control function controls the access signalling (request and grant) procedures for the radio channel, and the mapping of LLC frames onto the GSM physical channel.</Section> <Section>1.2 LLC - Logical Link Control</Section> <Section>The LLC entity provides multiple highly reliable logical links for asynchronous data transfer between the MS and the network. It supports variable-length information frames, acknowledged and unacknowledged data transfer, flow and sequence control, error detection and recovery, notification of unrecoverable errors, user identity confidentiality, and ciphering of user and signaling data.</Section> <Section>1.3 GMM - GPRS Mobility Management</Section> <Section>The GMM entity provides procedures for the mobility of the MS, such as informing the network of its present location, and user identity confidentiality. It manages the GMM context (attach, detach, routing area updating), supports security functions such as authentication of user and MS, controls ciphering of data, and initiates the response to paging messages.</Section> <Section>1.4 SM - Session Management</Section> <Section>The main function of the session management (SM) is to support PDP context handling of the user terminal. Session Management activates, modifies and deletes the contexts for packet data protocols (PDP). Session Management services are provided at the SMREG-SAP and the SNSM-SAP for anonymous and non-anonymous access. The non-anonymous and anonymous access procedures for PDP context activation and PDP context deactivation are available at the SMREG-SAP. In addition there exists a PDP context modification for non-anonymous PDP contexts.</Section> <Section>1.5 SNDCP - Subnetwork Dependant Convergence Protocol</Section> <Section>SNDCP carries out all functions related to transfer of Network layer Protocol Data Units (N-PDUs) over GPRS in a transparent way. SNDCP helps to improve channel efficiency by means of compression techniques. The set of protocol entities above SNDCP consists of commonly used network protocols. They all use the same SNDCP entity, which then performs multiplexing of data coming from different sources to be sent using the service provided by the LLC layer.</Section> <Section>1.6 GACI - GPRS Application Control Interface</Section> <Section>The GACI is the GPRS extension of the ACI. It is specified in GSM 07.07 and 07.60. It is responsible for processing of the GPRS related AT Commands to setup, activate and deactivate the PDP context parameter. It also provides functionality for the interworking between GMM/SM/SNDCP and a packet oriented protocol like PPP.</Section> <Section>1.7 USART - Universal Synchronous Asynchronous Receiver Transmitter Driver</Section> <Section>The USART is a hardware component that facilitates a connection between the mobile station and terminal equipment (e.g. a PC). This interface uses some of the circuits described in V.24.</Section> <Section>The data exchange provided by this unit is serial and asynchronous (synchronous communication is not in the scope of this document). A driver that uses interrupts to manage a circular buffer for the sending and receiving direction is necessary in order to use this component in the GPRS. The driver has to be able to perform flow control.</Section> <Section>1.8 TOM - Tunnelling of Messages</Section> <Section>The TOM entity is present if and only if HS136 is supported (the feature flag FF_HS136 is enabled).</Section> <Section>The main function of TOM is to tunnel non-GSM signalling messages between the MS and the SGSN. The only non-GSM signalling which is currently supported by TOM is for the EGPRS-136 system (according to TIA/EIA-136-376). Data transfer in both uplink and downlink direction is possible. Two different priorities (high, low) of signalling data transfer are supported. TOM uses the unacknowledged mode of LLC and the acknowledged mode of GRR (RLC/MAC).</Section> </Description> <DocHistory> <DocVersion Number="001" Year="99"/> <Date Day="25" Month="6" Year="1999"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Initial</Comment> </DocHistory> <DocHistory> <DocVersion Number="002" Year="99"/> <Date Day="6" Month="7" Year="1999"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Macro names changed ("LLGMM_*"), some variable names changed ("llgmm_*")</Comment> </DocHistory> <DocHistory> <DocVersion Number="003" Year="99"/> <Date Day="9" Month="8" Year="1999"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Included changes due to GSM 04.64 Version 6.4.0 (removed WINDOW-REQ, WINDOW-CNF, List of LLC state variables)</Comment> </DocHistory> <DocHistory> <DocVersion Number="004" Year="99"/> <Date Day="14" Month="10" Year="1999"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Corrected opcodes of primitives</Comment> </DocHistory> <DocHistory> <DocVersion Number="005" Year="99"/> <Date Day="7" Month="1" Year="2000"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Removed parameter "assign" in LLGMM_ASSIGN_REQ</Comment> </DocHistory> <DocHistory> <DocVersion Number="006" Year="99"/> <Date Day="26" Month="1" Year="2000"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Changed LLC error cause values to take GRR error causes into account</Comment> </DocHistory> <DocHistory> <DocVersion Number="007" Year="99"/> <Date Day="24" Month="2" Year="2000"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Removed error cause FRMR_RECEIVED_REEST</Comment> </DocHistory> <DocHistory> <DocVersion Number="008" Year="99"/> <Date Day="23" Month="3" Year="2000"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Trigger Cause values set according to GRR_DATA_REQ cause values</Comment> </DocHistory> <DocHistory> <DocVersion Number="009" Year="99"/> <Date Day="26" Month="5" Year="2000"/> <Author>DB</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>Ciphering Algorithm values adapted to air interface messages</Comment> </DocHistory> <DocHistory> <DocVersion Number="010" Year="99"/> <Date Day="26" Month="9" Year="2001"/> <Author>ANS</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>llgmm_suspend_req enhanced</Comment> </DocHistory> <DocHistory> <DocVersion Number="011" Year="99"/> <Date Day="28" Month="2" Year="2002"/> <Author>ANS</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>llgmm_suspend_req enhanced</Comment> </DocHistory> <DocHistory> <DocVersion Number="012" Year="99"/> <Date Day="13" Month="3" Year="2002"/> <Author>ANS</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>llgmm_suspend_req enhanced</Comment> </DocHistory> <DocHistory> <DocVersion Number="013" Year="99"/> <Date Day="11" Month="11" Year="2002"/> <Author>UT</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>remove llgmm_trigger_ind</Comment> </DocHistory> <DocHistory> <DocVersion Number="014" Year="99"/> <Date Day="21" Month="3" Year="2003"/> <Author>ANS</Author> <DocStatus State="BEING_PROCESSED"/> <Comment>llgmm_tlli_ind</Comment> </DocHistory> <DocRef> <RefId>[1]</RefId> <RefTitle>GSM 05.02 version 8.0.0 Release 1999Digital cellular telecommunications system (Phase 2+);Multiplexing and multiple access on the radio path</RefTitle> </DocRef> <DocRef> <RefId>[2]</RefId> <RefTitle>GSM 04.60 version 6.3.0 Release 1997Digital cellular telecommunications system (Phase 2+);General Packet Radio Service (GPRS);Mobile Station (MS) - Base Station System (BSS) interface;Radio Link Control/ Medium Access Control (RLC/MAC) protocol</RefTitle> </DocRef> <DocRef> <RefId>[3]</RefId> <RefTitle>GSM 04.08 version 6.3.0 Release 1997Digital cellular telecommunications system (Phase 2+);Mobile radio interface layer 3 specification</RefTitle> </DocRef> <DocRef> <RefId>[4]</RefId> <RefTitle>GSM 03.64 version 6.1.0 Release 1997Digital cellular telecommunications system (Phase 2+);General Packet Radio Service (GPRS);Overall description of the GPRS radio interface;
