4 The entities and interfaces within the mobile network
utilising the GLR
4.1 The entities of the mobile system
The functional entities related to the GLR are described below. The description of each entity is detailed in 3GPP TS
23.119 (GLR stage2 specification). The other functional entities described in the present document (e.g. MSC, VLR,
and HLR) are specified in 3GPP TS 29.002.
- The Gateway location Register (GLR).
- The Intermediate MSC (IM-MSC).
- The Intermediate GSN (IM-GSN).
4.2 The Interfaces within the mobile services
The Interfaces related to the GLR are described below. The description of each interface is detailed in 3GPP TS 23.119
(GLR stage2 specification).
- Interface between the HLR and the GLR.
- Interface between the VLR and the GLR.
- Interface between the MSC and the IM_MSC.
- Interface between the SGSN and the GLR.
- Interface between the MSC and the GLR.
- Interface between the GLR and the IM_GSN.
5 Overload and compatibility overview
5.1 Overload control for MAP entities
The VLR and SGSN see the GLR as an HLR, and the HLR sees the GLR as a VLR or a SGSN. Therefore the GLR
shall behave like mobile entity as which the GLR is regarded. If overload of the GLR is detected, the responder may
ignore requests for certain MAP operations (see tables 5.1/1, 5.1/2 and 5.1/3 in 3GPP TS 29.002). The decision as to
which MAP Operations may be ignored is made by the MAP service provider and is based upon the priority of the
application context.
5.2 Compatibility
A version negotiation mechanism based on the use of an application-context-name is used to negotiate the protocol
version used between two entities for supporting a MAP-user signalling procedure. The description of the version
negotiation mechanism is detailed in 3GPP TS 29.002.

6 Requirements concerning the use of SCCP and TC
6.1 Use of SCCP
The Mobile Application Part makes use of the services offered by the Signalling Connection Control Part of signalling
System No. 7. CCITT Blue Book or ITU-T (03/93) Recommendations Q.711 to Q.716 should be consulted for the full
specification of SCCP. In North America (World Zone 1) the national version of SCCP is used as specified in ANSI
T1.112.
6.1.1 SCCP Class
MAP will only make use of the connectionless classes (0 or 1) of the SCCP.
6.1.2 Sub-System Number (SSN)
The Application Entities (AEs) defined for MAP consist of several Application Service Elements (ASEs) and are
addressed by sub-system numbers (SSNs). The SSN for MAP are specified in 3GPP TS 23.003 [1]. The specific SSN is
not needed for the GLR, IM_MSC, and IM_GSN.
6.1.3 SCCP addressing
6.1.3.1 Introduction
The format and coding of address parameters carried by SCCP are detailed in 3GPP TS 29.002.
The following subclauses describe the method of SCCP addressing appropriate for each entity both for the simple intra-
PLMN case and where an inter-PLMN communication is required. The following entities are considered for the GLR
additionally:
- the Gateway location Register (GLR);
- the Intermediate Mobile-services Switching Centre (IM_MSC);
- the Intermediate GPRS Support Node (IM_GSN).
6.1.3.2 The Gateway Location Register (GLR)
6.1.3.2.1 Addressed by the VLR
In the network utilising the GLR, when an MS that belongs to other PLMN registers in a VLR/SGSN, the VLR/SGSN
sees the GLR as the MS’s HLR. When initiating the update location dialogues, the VLR is able to address the GLR
based on the SPC of the GLR because of intra-PLMN signalling. And the VLR can address the GLR based on an E.214
Mobile Global Title originally derived by the VLR from the IMSI (when CCITT or ITU-T SCCP is used), or an E.212
number originally derived from IMSI (when ANSI SCCP is used, an IMSI). When answering with Global Title to the
VLR, the GLR shall insert its E.164 address in the Calling Party Address of the SCCP message containing the first
responding CONTINUE message. After that, the VLR can address the GLR based on an E.164 GLR address.
6.1.3.2.2 Addressed by the HLR
When a location updating dialogue initiated by a GLR has been successfully completed, the HLR sees the GLR as the
VLR. When initiating dialogues towards the VLR, the routeing information used by the HLR is derived from the
E.164 VLR number received as a parameter of the MAP message initiating the update location dialogue, but in reality
the HLR addresses the GLR using the VLR number.
ETSI
3GPP TS 29.120 version 12.0.0 Release 12 11 ETSI TS 129 120 V12.0.0 (2014-10)
6.1.3.2.3 Addressed by the GMSC
In the case that the MS is served by the SGSN in the network utilising the GLR, the GMSC sees the GLR as the SGSN.
When the GMSC initiates dialogues towards the SGSN the SGSN (MAP) SSN (See 3GPP TS 23.003) shall be included
in the called party address. The routeing information used by the GMSC is derived from the E.164 SGSN number
received as a parameter of the MAP message initiating the forward short message procedure. But in reality the GMSC
addresses the GLR using the SGSN number.
6.1.3.2.4 Addressed by the IM-GSN
In the network utilising the GLR, the IM-GSN initiates the GPRS location information retrieval to the GLR. The IM-GSN
must have the value of the GLR address beforehand.
6.1.3.3 The Intermediate MSC (IM_MSC)
6.1.3.3.1 Addressed by the GMSC
When a short message for CS has to be routed to an MS, the GMSC addresses the MSC by an MSC identity received
from the HLR that complies with E.164 rules. But in reality the GMSC addresses the IM-MSC in the network utilising
the GLR.
6.1.3.3.2 Addressed by the GMLC
When a location request for a particular MS needs to be sent to the MS’s VMSC, the GMLC addresses the MSC using
an E.164 address received from the MS’s HLR. But in reality the GMLC addresses the IM-MSC in the network utilising
the GLR.
6.1.3.4 The Intermediate GSN (IM_GSN)
The IM-GSN provides routing of the Network-Requested PDP Context activation. If a Network-Requested PDP
Context activation fails, the GLR will alert the IM-GSN when the subscriber becomes reachable. The GLR will use
the E.164 IM-GSN number received as parameter of the MAP message reporting the failure.
6.1.3.5 Summary table
The following table summarises the SCCP address used for invoke operations. As a principle, within a PLMN either an
SPC or a GT may be used (network operation option), whereas when addressing an entity outside the PLMN the GT
must be used. The address type mentioned in the table (e.g. MSISDN) is used as GT or to derive the SPC.
For a response, the originating address passed in the invoke message is used as SCCP Called Party Address. For
extra-PLMN addressing the own E.164 entity address is used as SCCP Calling Party Address; for intra-PLMN
addressing an SPC derived from the entity number may be used instead. When using an SPC, the SPC may be taken
directly from MTP.
