        <Description>
            <Section>The Protocol Stacks are used to define the functionality of the GSM protocols for interfaces. 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 fax and data transmission consists of several entities. Each entity has one ore more service access points, over which the entity provides a service for the upper entity. The entity, which is described in this document, is coloured grey in the following figure :</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>

                <Section>Used to identify a PDU going from SNDCP to CCI and back to SNDCP. In case of uplink transfer (CCI_DECOMP_IND) SNDCP provides 'ref_nsapi' and 'ref_npdu_num'. The segment number 'ref_seg_num' has to be set by CCI. The reference shall then copied to the CCI_COMP_IND going back to SNDCP.</Section>
                <Section>In case of downlink transfer CCI just passes the pdu_ref from the incoming CCI_DECOMP_REQs to the one outgoing CCI_DECOMP_IND, ignoring the 'ref_seg_num' field.</Section>
                <Section>Since the DATA primitives are N-PDUs, the 'ref_seg_num' field is not valid for them. It will only be evaluated or set for the TRANSFER primitives (because they represent segments).</Section>
