The present document specifies the stage 2 of the LoCation Services (LCS) feature in GERAN, which provides the mechanisms to support mobile location services for operators, subscribers and third party service providers.
The purpose of this stage 2 specification is to define the GERAN LCS architecture, functional entities and operations to support location methods. This description is confined to the aspects of LCS within the GERAN and does not define nor describe the LCS entities or operations within the Core Network.
Location Services may be considered as a network provided enabling technology consisting of standardised service capabilities, which enable the provision of location applications. The application(s) may be service provider specific. The description of the numerous and varied possible location applications which are enabled by this technology are outside the scope of the present document. However, clarifying examples of how the functionality being described may be used to provide specific location services may be included.
This stage 2 specification covers the GERAN LCS functional model and entities, the location methods, state descriptions, and message flows.

The present document defines the stage 2 service description for a Generic Access Network (GAN) . It describes the GAN system concepts, documents the reference architecture, functional entities, network interfaces, and high-level procedures.
GAN supports two modes of operation:
- GAN A/Gb mode
- GAN Iu mode
GAN A/Gb mode supports an extension of GSM/GPRS mobile services that is achieved by tunnelling Non Access Stratum (NAS) protocols between the MS and the Core Network over an IP network and the A and Gb interfaces to the MSC and SGSN, respectively.
GAN Iu mode supports an extension of UMTS mobile services that is achieved by tunnelling Non Access Stratum (NAS) protocols between the user equipment (MS) and the Core Network over an IP network and the Iu-cs and Iu-ps interfaces to the MSC and SGSN, respectively.
Both GAN modes are complements to traditional GERAN/UTRAN/E-UTRAN radio access network coverage.

High level areas that are studied are e.g. potential placement of transcoders in the core network, effective bandwidth utilisation at the A-interface, impact on call related messages, payload formats.
The following items shall be covered in the study:
- In the target solution it is wanted to transfer compressed speech as far as possible end-to-end to achieve efficient transport and speech quality. The possibility to free GERAN from handling all kind of transcoders shall be studied, and the architecture might place Codecs in the core network.
- Impacts/changes on current A-interface procedures resulting from placing transcoders in the core network as well as in the BSS shall be studied, e.g. impacts on the assignment and handover procedures.
- In addition to allow compressed speech over the A-interface the study shall provide further solution for effective bandwidth utilisation at the A interface, which means it shall describe multiplexing of RTP flows and how this will be negotiated between the BSS and CN nodes.
- The study shall describe a solution for "true end-to-end Codec negotiation", which considers on a call basis the preference/situation of the radio network.
- It shall be studied how call related messages have to be adapted, e.g. transfer of Codec related information, identification of calls/sessions.
- The study shall describe the wanted payload formats and other relevant user plane parameters like packetization time etc.

The present document describes in general terms the Link Access Procedures on the Dm channel, LAPDm. The application of this protocol to other channel types is for further study. Details are provided in 3GPP TS 44.006.
The purpose of LAPDm is to convey information between layer 3 entities across the GSM PLMN radio interface (MS to network interface) using the Dm channel.
NOTE 1: The term Dm channel is used for convenience to designate the collection of all the various signalling channels required in the GSM system. See also 3GPP TS 44.003.
The definition of LAPDm is based on the principles and terminology of:
‑ ITU-T Recommendations X.200 and X.210: the reference model for Open Systems Interconnection (OSI);
‑ ITU-T Recommendations Q.920 and Q.921: the specification of LAPD for the user‑network interface in ISDN;
‑ ITU-T Recommendation X.25 LAPB: user‑network interface for packet mode terminals; and
‑ ISO/IEC 3309 and ISO 4335: High‑level Data Link Control (HDLC) standards for frame structure and elements of procedures.
LAPDm is a protocol that operates at the data link layer of the OSI architecture. The relationship between the data link layer and other protocol layers is defined below.
NOTE 2: The interface between the mobile station and external terminal equipment/terminal adapters is defined in the Technical Specifications of the GSM 07‑series.
NOTE 3: The physical layer on the radio interface is defined in 3GPP TS 44.004 and layer 3 is defined in 3GPP TS 24.007, 3GPP TS 44.018, 3GPP TS 24.010 and 3GPP TS 24.011. Reference should be made to these Technical Specifications for the complete definitions of the protocols and procedures across the GSM PLMN radio interface.
NOTE 4: The term "data link layer" is used in the main text of the present document. However, mainly in figures and tables, the terms "layer 2" and "L2" are used abbreviations. Furthermore, in accordance with 3GPP TS 24.007 and 3GPP TS 44.018 the term "layer 3" is used to indicate the layer above the data link layer.
LAPDm is independent of the transmission bit rate. It requires physical channels with characteristics as defined in 3GPP TS 44.003.
Clause 2 below describes basic concepts used in the present document and 3GPP TS 44.006.
Clause 3 gives an overview description of LAPDm functions and procedures.
Clause 4 summarizes the services that the data link layer provides to layer 3 and the services that the data link layer requires from the physical layer.
Clause 5 provides an overview of the data link layer structure.

The present document specifies measurable performance requirements for signalling aspects of Mobile Stations (MS)s. To allow implementation flexibility it has been chosen to specify requirements on the whole Mobile Station rather than to specify requirements on each "OSI layer". As a consequence the performance requirements do not fit conveniently in specifications such as 3GPP TS 24.008 [4] and 3GPP TS 44.018 [4a] (layer 3 only) or 3GPP TS 44.006 [3] (layer 2 only).
The main aim of the present document is to provide the justification for testing of requirements that are not included in other GSM specifications. Where specific requirements are included in other GSM specifications they are not duplicated here.
MSs have to perform a wide variety of functions. As a consequence most performance measurements have to be made under a set of defined conditions: where necessary, these are included in the present document.
Where necessary certain assumptions are made about the interaction times between the mobile equipment and the SIM. If the (test) SIM does not respond within the assumed time then appropriate allowances shall be made.
Additionally, it is intended that the present document should contain sufficient requirements to enable some undefined network timers in 3GPP TS 24.008 [4] and 3GPP TS 44.018 [4a] to be calculated.

The present document specifies for Mobile Stations (MS), for the digital cellular communications system and Personal Communication Systems (PCS) operating in the 900 MHz and 1800 MHz band (GSM900 and DCS1800), standardized by 3rd Generation Partnership Project (3GPP), those ME functions which are required for conformance testing purposes only. However, except for the Electrical Man Machine Interface (EMMI) and the Multi-slot TCH Loops, they are required for every mobile station.
For conformance tests, functions are activated via the radio interface, test SIM or dedicated pins. These functions must be capable of being activated when a test SIM is present but must not function with any other (e.g. network) SIM present except where otherwise stated within the present document. In this state, the MS must be able to perform all functions specified in the present document; in addition however, the special conformance testing functions must be operational.
The special conformance testing functions of the ME are enabled by use of a dedicated Subscriber Identity Module (test SIM, see 3GPP TS 51.010-1 Annex 4). SIM, in general, is described in 3GPP TS 51.011. The ME recognizes the test SIM by the Administrative Data Field.
The present document applies to the public land mobile radio service in the GSM900 and DCS1800 systems, using constant envelope modulation and operating on radio frequencies in the 900 and 1800 MHz bands respectively with a channel separation of 200 kHz and carrying 8 full rate channels or 16 half rate channels per carrier according to the TDMA principle.
The present document is part of the 3GPP TS series of technical specifications. The present document neither replaces any of the other GSM technical specifications or GSM related TS, nor is it created to provide full understanding of (or parts of) the GSM900 and DCS1800 systems.
The present document applies to the unit which includes the hardware to establish a connection across the radio interface.

The present document defines the Logical Link Control (LLC) layer protocol to be used for packet data transfer between the Mobile Station (MS) and Serving GPRS Support Node (SGSN).
It defines the frame structure, elements of procedure, format of fields, and procedures for the proper operation of the logical link control layer. It is based on ideas contained in IS-130 [21], ISO 3309 [16], ISO 4335 [17], and ISO 7809 [18, 19, 20] (HDLC of ISO), as well ITU-T Q.920 [13] and Q.921 [14] (LAPD). The concepts, the overview description of LLC layer functions and procedures, and the relationship with other Technical Specifications are described in general terms in 3GPP TS 23.060 [5].
LLC spans from the Mobile Station (MS) to the Serving GPRS Support Node (SGSN). LLC is intended for use with both acknowledged and unacknowledged data transfer.
The frame formats defined for LLC are based on those defined for LAPD and RLP. However, there are important differences between LLC and other protocols, in particular with regard to frame delimitation methods and transparency mechanisms. These differences are necessary for independence from the radio path.
The LLC procedures are modelled upon the concepts of HDLC as outlined in ISO 4335. Data sequence integrity between the data source and data sink is effected by means of a cyclic numbering scheme. An independent numbering scheme is used for each logical data link, as identified by the a data link connection identifier. LLC supports two modes of operation:
- Unacknowledged peer-to-peer operation:
A logical link entity may initiate transmissions to a peer entity without prior establishment of a logical connection with the peer entity. LLC does not guarantee in-order delivery. LLC can detect errors in a received frame, and, depending on whether the frame is sent in protected mode or not, either discard or deliver the erroneous frame. No error recovery procedures are defined at the LLC layer. Higher-layer protocols can be used to provide reliability, if needed. This mode of operation is known as Asynchronous Disconnected Mode (ADM).
- Acknowledged peer-to-peer operation:
A balanced data link involves two participating entities, and each entity assumes responsibility for the organisation of its data flow and for error recovery procedures associated with the transmissions that it originates. Each entity operates as both a data source and data sink in a balanced link, allowing information to flow in both directions. This mode of operation is known as Asynchronous Balanced Mode (ABM), and provides a reliable service with in-order delivery.
In unacknowledged operation, LLC can provide integrity protection.
The present document is organised as follows:
- An overview of the LLC layer functions is given in clause 4.
- The frame structure for peer-to-peer communication is given in clause 5.
- The elements of procedure and formats of fields are given in clause 6.
- The elements of layer-to-layer communication are contained in clause 7.
- The details of the peer-to-peer ABM procedures are given in clause 8.

The present document provides the description of the Subnetwork Dependent Convergence Protocol (SNDCP) for the General Packet Radio Service (GPRS).
The user of the services provided by SNDCP is a packet data protocol (PDP) at the mobile Station (MS) or the Relay at the Serving GPRS Support Node (SGSN). Additionally, a control entity, e.g. AT command interpreter, may be an SNDCP user. SNDCP uses the services provided by the Logical Link Control (LLC) layer 4 and the Session Management (SM) sub-layer 2.
The main functions of SNDCP are:
- Multiplexing of several PDPs.
- Compression / decompression of user data.
- Compression / decompression of protocol control information.
- Segmentation of a network protocol data unit (N‑PDU) into Logical Link Control Protocol Data Units (LL‑PDUs) and re-assembly of LL‑PDUs into an N‑PDU.
3GPP TS 44.065 is applicable to GPRS MS and SGSN.

This Technical Report provides background information, motivations, concepts and requirements regarding an extended Network Assisted Cell Change (NACC) feature for external cell change support. Cell change between GERAN and UTRAN cells is outside the scope of this report, although consideration has been taken in order to allow an easier extensibility to that case. The extension is based on the Release 4 version of the NACC feature where the mobile station is only supported by the NACC when performing internal cell re-selection, i.e. within a BSC. The extension of the feature is for GERAN just affecting BSS and for the core network the SGSN and signalling links between these network nodes. To support cell changes between GERAN and UTRAN, also the Um and the Uu interfaces are affected.
The evolved Release 4 NACC proposal as described in this TR provides the basis for the detailed Stage 2 and stage 3 specification work. The feature will be developed in a phased approach and a longer-term vision is presented in the report.
The focus of the TR is to:
- Define the requirements on different nodes
- Specify the requirements for the interfaces
- Propose a plan for the work item project
- Evaluation of what does and does not need to be standardised

The present document defines the requirements for the transceiver of the pan‑European digital cellular telecommunications systems GSM.
Requirements are defined for two categories of parameters:
- those that are required to provide compatibility between the radio channels, connected either to separate or common antennas, that are used in the system. This category also includes parameters providing compatibility with existing systems in the same or adjacent frequency bands;
- those that define the transmission quality of the system.
The present document defines RF characteristics for the Mobile Station (MS) and Base Station System (BSS). The BSS will contain Base Transceiver Stations (BTS), which can be normal BTS,micro‑BTS or pico-BTS. The precise measurement methods are specified in 3GPP TS 51.010 and 3GPP TS 51.021.
Unless otherwise stated, the requirements defined in this EN apply to the full range of environmental conditions specified for the equipment (see annex D).
In the present document some relaxations are introduced for GSM 400 MSs, GSM 900 MSs, GSM 700 MSs and GSM 850 MSs which pertain to power class 4, 5 or 6 (see subclause 4.1.1). In the present document these Mobile Stations are referred to as "small MS".
In the present document some relaxations to receiver requirements are introduced for a MS indicating support for Downlink Multi Carrier (DLMC), see 3GPP TS 24.008, when in DLMC configuration. DLMC configurations are specified for only GSM 850, GSM 900, DCS 1800 and PCS 1900.
MSs may operate on more than one of the frequency bands specified in clause 2. These MSs are referred to as "Multi band MSs" in this EN. Multi band MSs shall meet all requirements for each of the bands supported. The relaxation on GSM 400 MSs, GSM 900 MSs, GSM 700 MSs and GSM 850 MSs for a "small MS" are also valid for a multi band MS if it complies with the definition of a small MS.
The RF characteristics of repeaters are defined in annex E of this EN. Annexes D and E are the only clauses of this EN applicable to repeaters. Annex E does not apply to the MS or BSS. The precise measurement methods for repeaters are specified in 3GPP TS 51.026 [35].
The present document also includes specification information for mixed mode operation at 850 MHz and 1900 MHz (MXM 850 and MXM 1900). 850 MHz and 1900 MHz mixed-mode is defined as a network that deploys both 30 kHz RF carriers and 200 kHz RF carriers in geographic regions where the Federal Communications Commission (FCC) regulations are applied or adopted.
The requirements for a MS in a mixed-mode system, MXM 850 and MXM 1900, correspond to the requirements for GSM 850 MS and PCS 1900 MS respectively.
Annex M defines the minimum performance requirements for A-GPS for MSs that support A-GPS. Annex M does not apply to the BSS.
The present document also includes specific requirements for multicarrier BTS, wherever explicitly stated in the text, that apply for all classes of multicarrier BTS (Wide Area, Medium Range and Local Area) if nothing else is stated. All other requirements designated for BTS and normal BTS apply if not otherwise stated. The multicarrier BTS classes have relaxed requirements in the areas of Tx spurious emissions, intermodulation attenuation and, when multicarrier receiver is included, Rx blocking. Usage of multicarrier BTSs in some geographical regions might be subject to regulatory restrictions to protect other radio systems operating in bands of adjacent frequency assignments, in particular for all safety related applications like railway applications. In areas where such systems coexist with multicarrier BTSs, the received interference power originating from multicarrier BTSs might have to be limited.
The document also includes entry points in some tables for the multicarrier BTS requirements to which TS 37.104 [33] for Multi-Standard Radio Base Stations (MSR BS) is referring to as specific GSM/EDGE single-RAT requirements not covered by the general requirements. These entry points are marked with M) and, as described in a note in each applicable table, identify the relevant column(s) that are applicable as MSR BS requirements. In general the requirements for multicarrier BTS equipped with multicarrier receiver also apply to Multi-Standard Radio Base Stations. The GSM requirements for Multi-Standard Radio Base Stations are defined for GSM 850, GSM 900, DCS 1800 and PCS 1900 only. Requirements for other frequency bands and MXM base stations are excluded. Annex P defines the minimum performance for the receiver in MSR BS.
For equipment not declared as MSR BS the M) indications can be ignored.
The present document defines requirements for the usage of the ER-GSM band. The national implementation might be subject to regulatory coordination agreements to avoid system impacts (RF scenarios for ER-GSM introduction are given in 3GPP TR 45.050).
The present document defines requirements for supporting a low-complexity, low data throughput service in environments experiencing high propagation attenuation as indoors in basements etc. This service, based on EGPRS, with extended coverage is called EC-GSM-IoT. For EC-GSM-IoT, in case no specific requirement is explicitly stated, the requirements for EGPRS apply.

TSG GERAN has agreed that the standardisation of DARP be independent of a release. However, in order to implement an MS that conforms to a particular release but supports DARP, which is specified in a later release, it is necessary to specify some extra requirements.
DARP - phase II is contained in the Release 7 specifications. In order to implement an MS conforming to Release 5 but supporting DARP – phase II, it is necessary for the MS to additionally conform to some parts of the Release 7 specifications, such as the radio frequency requirements for DARP and some signalling extensions relating to the MS Classmark and radio access capabilities.

The present document provides a study into BTS energy saving solutions. The present document analyses and evaluates different solutions to determine the benefits provided compared to the legacy BTS energy consumption.
In the scope of this study there are following solutions:
- Reduction of Power on the BCCH carrier (potentially enabling dynamic adjustment of BCCH power)
- Reduction of power on DL common control channels
- Reduction of power on DL channels in dedicated mode, DTM and packet transfer mode
- Deactivation of cells (e.g. Cell Power Down and Cell DTX like concepts as discussed in RAN [4])
- Deactivation of other RATs in areas with multi-RAT deployments, for example, where the mobile station could assist the network to suspend/minimize specific in-use RATs at specific times of day
- And any other radio interface impacted power reduction solutions
The solutions will also consider the following aspects:
- Impacts on the time for legacy and new mobile stations to gain access to service from the BTS
- Impacts on legacy and new mobile stations to keep the ongoing service (without increasing drop rate)
- Impacts on legacy and new mobile stations implementation and power consumption, e.g. due to reduction in DL power, cell (re-)selection performance, handover performance, etc.

The transcoding procedure specified in the present document is applicable for the full‑rate Traffic Channel (TCH) in the digital cellular telecommunications system. The use of this transcoding scheme for other applications has not been considered.
In GSM 06.01, a reference configuration for the speech transmission chain of the digital cellular telecommunications system is shown. According to this reference configuration, the speech encoder takes its input as a 13 bit uniform PCM signal either from the audio part of the mobile station or on the network side, from the PSTN via an 8 bit/A‑ or -law (PCS 1900) to 13 bit uniform PCM conversion. The encoded speech at the output of the speech encoder is delivered to a channel encoder unit which is specified in GSM 05.03. In the receive direction, the inverse operations take place.
The present document describes the detailed mapping between input blocks of 160 speech samples in 13 bit uniform PCM format to encoded blocks of 260 bits and from encoded blocks of 260 bits to output blocks of 160 reconstructed speech samples. The sampling rate is 8000 sample/s leading to an average bit rate for the encoded bit stream of 13 kbit/s. The coding scheme is the so‑called Regular Pulse Excitation ‑ Long Term prediction ‑ Linear Predictive Coder, here‑after referred to as RPE‑LTP.
The present document also specifies the conversion between A‑ and -law (PCS 1900) PCM and 13 bit uniform PCM. Performance requirements for the audio input and output parts are included only to the extent that they affect the transcoder performance. The present document also describes the codec down to the bit level, thus enabling the verification of compliance to the present document to a high degree of confidence by use of a set of digital test sequences. These test sequences are described and are contained in archive en_300961v080101p0.ZIP which accompanies the present document.

The present document gives the principles on which the detailed interface specifications in the rest of the 3GPP TS 48.0xx series of Technical Specifications are based.
The set of fixed equipment accessed from the MSC through one particular instance of the interface will be later referred to as a Base Station System (BSS). A BSS ensures the coverage of n cells, where n can be 1 or more.
The function of a BSS may be further subdivided into a control function, performed by one Base Station Controller (BSC) and a transceiving function, performed by "n" Base Transceiver Station equipments (BTS), one for each cell. However, the study of such a split is outside the scope of the 48.0xx series of Technical Specifications, where the BSS will be considered as a whole.
The BSS-MSC interface defined in the 3GPP TS 48 series of Technical Specifications is designed to support a wide range of possible architectures on both sides. Characteristics like location of the transcoders/rate adaptation to the MSS or inside the BSS (either physically integrated into the transceivers or very near to the MSC) or the use of traffic or signalling concentration at either side are left to the operators' choice. Annex A to the present document contains guidance information concerning the use of remote mobile switching units, which for the purposes of the present document are considered as part of the MSC.
The BSS-MSC interface is commonly called "A-Interface". It is subdivided into the Control Plane (signalling) and the User Plane (traffic). Throughout this document the term "MSC" is used to reflect both planes of the Mobile Core Network, although in some architecture the Mobile Core Network is split into MSC-Server (MSC-S) and Media Gateway (MGW).
Direct connection between two BSSs is not supported by this A-Interface.
This A-Interface may be based on
- TDM using 1 or more 2 048 kbit/s digital transmission system interfaces. Each 2 048 kbit/s interface provides 31*64 kbit/s channels which can be used for traffic (User Plane) or signalling (Control Plane) as the operator requires, and/or
- IP supporting User Plane and/or Control Plane (SIGTRAN).The signalling is layered, terminology similar to that in the OSI reference model is used in this series, however the layers referred to are not identical to the equivalently named layer in the OSI model.
This A-Interface User Plane is defined at the boundary of the MSC and
- in case of TDM, it has a per channel bit rate of 64 kbit/s, but the net radio path traffic channel is at a rate of less than 16 kbit/s. A speech transcoder or data rate adapter function is thus needed for the rate conversion. The interface is designed such that the transcoding or rate adaptation function may be geographically situated at either the MSC site or the BSS site, however the transcoder is considered to be part of the BSS
- in case of IP, it has a flexible channel bit rate, adapted to the payload size. The speech transcoding function can be part of either the BSS or the Core Network or can be omitted (transcoding free operation), allowing e.g. for use of both, PCM encoded speech and compressed speech, over the A-Interface. The data rate adapter function is always located inside the BSS, using a 64kbit/s unrestricted digital interface (Clearmode) over IP.
The A-Interface has been designed around the aims of 3GPP TS 48.001 allowing each component and the system as a whole to evolve.

The present document is split into four parts, clauses 4 to 6 dealing with the MTP, clause 6a dealing with M3UA/SCTP, clause 7 dealing with interface functions towards higher layers and clauses 8 to 10 dealing with the SCCP and its use.
The MTP provides a mechanism giving reliable transfer of signalling messages. Clauses 4 to 7 of the present document deal with the subset of the MTP that can be used between an BSS and an MSC, which is compatible with a full MTP.
The M3UA/SCTP provides a mechanism giving reliable transfer of signalling messages over an IP network.
The SCCP is used to provide a referencing mechanism to identify a particular transaction relating to for instance a particular call. Clauses 8 to 10 identify the SCCP subset that should be used between a BSS and an MSC. The SCCP can also be used to enhance the message routing for (for instance) operations and maintenance information.

The present document specifies the layer 3 procedures used on the Base Station System (BSS) to Mobile-services Switching Centre (MSC) interface for control of GSM services.
For the purposes of call control and mobility management, messages are not interpreted at the Base Station System (BSS) which acts as a relay function. These messages and procedures are documented in 3GPP TS 24.008, the only relevant issues covering these messages in the present document are those concerned with error conditions at the interface, and the headers that are required for the correct addressing of the messages. This is specified in more detail in 3GPP TS 48.002.
The functional split between MSC and BSS is defined in 3GPP TS 48.002 and states that the BSS is responsible for local radio resource allocation and in order to support this the required procedures between BSS and MSC are defined in detail in the present document.
3GPP TS 48.002 also states that the BSS is responsible for the scheduling of all CCCH/BCCH messages and therefore some procedures for providing the BSS with the necessary information to be passed on these channels for individual calls (i.e. paging) are defined in the present document, but the scheduling is not discussed.
This interface and consequently these layer 3 procedures are designed to support BSSs providing one or more cells.

The present document defines rate adaptation functions to be used in PLMN Base Station Systems (BSS) transcoders and IWF
- for adapting radio interface data rates to the 64 kbit/s used at the A-interface in A/Gb mode and
- for adapting radio interface data rates to the Iu interface in GERAN Iu mode in accordance with 3GPP TS 43.010.
The number of Base Station System - Mobile-services Switching Centre (BSS - MSC) traffic channels supporting data rate adaptation may be limited. In this case some channels may not support data rate adaptation. Those that do, shall conform to this specification.
NOTE: This specification should be considered together with 3GPP TS 44.021 to give a complete description of PLMN rate adaptation.

The present document contains the definition of the SMLCPP protocol to be used between two Serving Mobile Location Centres (SMLC).
The LCS architecture is described in 3GPP TS 43.059. The following aspects of it are relevant to the issue:
- each SMLC controls a number of LMUs, and a given LMU is under the direct control of a single SMLC;
- there is a direct communication path, independent of SMLCPP, between a LMU and the SMLC that controls it;
- deciphering keys are controlled by one SMLC in the location area and sent to other SMLCs in the same location area.
SMLCPP runs between two SMLC functions in the same PLMN. Transport is outside the scope of the present document. It assumes a transport service between these functions, as provided by BSSAP-LE. The present document assumes that the underlying transport (e.g., as described by BSSAP-LE specifications) provides for transport and routing for any two pairs of SMLCs which need to run SMLCPP exchanges.
The main functions of SMLCPP are described in [5]. The key aspects are:
a) allowing an SMLC to ask for and obtain information about Radio Interface Timing (RIT), as known from measurements done by LMUs not under its direct control;
c) allowing an SMLC, that controls deciphering keys in the location area, to sent them to other SMLCs in the same location area.

The use and general aspects of the A-bis interface are given in 3GPP TS 48.051.
The present document gives the principle basis for the rest of the specifications specifying the interface between the Base Station Controller, BSC, and the Base Transceiver Station, BTS, with its transceivers, TRX. These components together form the Base Station System, BSS. (The interface between MSC and the BSS is specified in 3GPP TS 48.001 and 3GPP TS 48.020).
The intention with this interface is to get a unified way of connecting remotely located BTSs/TRXs to a BSC allowing for the interconnection of BSCs and BTSs/TRXs from different manufacturers.
In order to keep the BTS as simple as possible, BTS contains only those functions which have to recide close to the radio interface.

The present document specifies the general structure of layer 3 and traffic management procedures and messages used on the A-bis interface to support signalling procedures as defined in 3GPP TS 24.008 and 3GPP TS 44.018. Support for Location Services (LCS) related signalling, as defined in 3GPP TS 23.071, is also included. 3GPP TS 23.071 identifies new A-bis signalling to support BTS-embedded Type B LMUs as well as standalone, Type B LMUs. The standalone Type B LMU supports the layer 1 and 2 signalling for the A-bis as well as the Location Service message defined in the present document.
The use and general aspects of the Base Station Controller (BSC) to Base Station Transceiver (BTS) interface (the A-bis interface) are given in 3GPP TS 48.051.
Network management procedures and messages for the A-bis interface are defined in 3GPP TS 08.59.
The functional split between BSC and BTS is defined in 3GPP TS 48.052. The procedures and messages required to support this split are defined in detail in the present document.

When 64 kbit/s traffic channels are used on the Abis interface, the speech shall be coded according to CCITT Recommendation G.711 and the data rate adaptation shall be as specified in 3GPP TS 44.021 and 3GPP TS 48.020.
In the case where 16 kbit/s traffic channels are used for full rate speech, enhanced full rate speech, Adaptive Multi-Rate speech, Adaptive Multi-Rate Wideband speech or full rate data service, then the present document shall apply for frame structure and for control of remote transcoders and additional rate adaptors.
For Adaptive Multi-Rate speech the present document specifies the 16 kBit/s submultiplexing, both for the full and the half rate traffic channels (TCH/AFS, TCH/AHS, TCH/WFS and O-TCH/WHS). The specification for 8 kBit/s submultiplexing is given in 3GPP TS 48.061, both for the full and the half rate traffic channels (TCH/AFS and TCH/AHS).
Additionally, the present document specifies the 32 kBit/s submultiplexing for Adaptive Multi-Rate Wideband speech. However it reuses the frame structure of the 16 kBit/s submultiplexing for Adaptive Multi-Rate speech.
The use and general aspects of the Abis interface are given in 3GPP TS 48.051.
NOTE: The present document should be considered together with the 3GPP TS 06 series of specifications, 3GPP TS 44.021 (Rate Adaptation on the MS-BSS Interface) and 3GPP TS 48.020 (Rate Adaptation on the BS/MSC Interface).
