Foreword
This second edition European Telecommunication Standard (ETS) has been produced by the Special
Mobile Group (SMG) Technical Committee (TC) of the European Telecommunications Standards Institute
(ETSI).
This ETS specifies the stage 2 description of the subscriber data management. This ETS corresponds to
GSM Technical Specification (GSM-TS) GSM 03.16 version 4.2.1.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS is not in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM Technical Specifications (GSM-TS) (note).
Reference is also made within this ETS to GSM 03.8x series. The specifications in the series can be
identified, with their full title, within the normative reference clause of this ETS by the last two digits of their
GSM reference number e.g. GSM 03.8x series, refers to GSM 03.81, GSM 03.82, etc.
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the Digital cellular telecommunications system. Historically, these
documents have been identified as GSM Technical Specifications (GSM-TS). These
TSs may have subsequently become I-ETSs (Phase 1), or ETSs (Phase 2), whilst
others may become ETSI Technical Reports (ETRs). GSM-TSs are, for editorial
reasons, still referred to in current GSM ETSs.
Transposition dates
Date of adoption of this ETS: 4 October 1996
Date of latest announcement of this ETS (doa): 29 February 1997
Date of latest publication of new National Standard
or endorsement of this ETS (dop/e): 31 August 1997
Date of withdrawal of any conflicting National Standard (dow): 31 August 1997

1 Scope
This second edition European Telecommunication Standard (ETS) gives the stage 2 description of the
subscriber data management handling between the Home Location Register (HLR) and the Visitor
Location Register (VLR).
A number of procedures require updating of subscriber information from HLR to VLR:
- location updating;
- restoration;
- modification of data by the operator;
- modification of data by the subscriber via the Mobile Station (MS).
Only the rules for the updating of subscriber data from the HLR to the VLR are described in this ETS.
Public Land Mobile Network (PLMN) specific and Unstructured Supplementary Service Data (USSD)
subscriber data are out of scope of this ETS.

3 Definitions and abbreviations
3.1 Definitions
Subscriber data to be stored in the HLR and VLR are defined in GSM 03.08 and GSM 03.8x and
GSM 03.9x-series of technical specifications.
Shared subscriber data:
Common subset of subscriber data defined to be stored in both the HLR and VLR. Subscriber data only
stored in the HLR is not part of shared subscriber data. Shared subscriber data includes:
BS Bearer Service (see GSM 02.02);
TS Teleservice (see GSM 02.03);
BSG Basic Service Group (see GSM 02.01, GSM 02.04 and GSM 03.11);
EBSG Elementary Basic Service Group (see GSM 03.11);
CBSG Collective Basic Service Group (see GSM 03.11).
Mandatory data:
Data required to form a self-consistent set of subscriber data. The context governs whether a specific
parameter is mandatory, e.g. the data set for a specific service may be optional, however if data for this
service is present, then parameters within this data set may be mandatory.
Mandatory data is defined by the service description (see e.g. GSM 03.6x, GSM 03.8x and
GSM 03.9x-series of technical specifications and GSM 03.15) and by PLMN defined requirements.
NOTE 1: The above definition is seen from a semantic point of view. Semantically, mandatory
parameters may be defined as syntactically optional or mandatory by the protocol.
Optional data:
Data which is defined as subscriber data, but which is not required to form a self-consistent set of
subscriber data; the context governs whether a specific parameter is optional.
Optional data is data which is defined by the service description (see e.g. GSM 03.6x, GSM 03.8x and
GSM 03.9x-series of technical specifications and GSM 03.15) or by PLMN defined requirements but is not
defined as mandatory data.

NOTE 2: The above definition is seen from a semantic point of view. Semantically optional
parameters are always defined as syntactically optional by the protocol.
Missing data:
Data which is mandatory in a given context but is not received nor is valid data available locally.
Unexpected data:
Data which is received and cannot be further processed. This may be either:
- optional data not required in a given context; or
- optional or mandatory data, required in this context but received with an unexpected value.
Overlapping data:
Two different cases of overlapping within subscriber data are possible:
- two or more parameters are to be stored at the same address in the data structure (see
subclause 4.4);
- two or more BSGs within a BSG list include or are identical with one and the same EBSG.
The following groups of subscriber information are defined:
- subscriber information (Group A):
- International Mobile Subscriber Identity (IMSI);
- basic Mobile Station International ISDN Number (MSISDN);
- category;
- subscriber status;
- basic service information (Group B):
- Bearer Service list;
- Teleservice list.
- Supplementary Service (SS) information (Group C):
- forwarding information;
- call barring information;
- Closed User Group (CUG) information;
- SS Data;
- Operator Determined Barring (ODB) information (Group D):
- ODB Data;
- roaming restriction information (Group E):
- roaming restriction due to unsupported feature;
- regional subscription information (Group F):
- regional subscription data.

4 General on handling of subscriber information
In general, the VLR stores only a subset of the subscriber data available in the HLR. Updating of
subscriber information shall be done in a way to make available and to keep consistency of data shared
between HLR and VLR.
Two different cases for the updating of subscriber data can be identified:
- framed operation: during location update or restoration a complete set of the shared subscriber
data needs to be inserted in the VLR;
- stand-alone operation: whenever subscriber data are added, deleted or changed in the HLR, this
may need partial insertion, deletion or change of shared subscriber data in the VLR.
Subclauses 4.1 to 4.4 explain the actions of the HLR and the VLR within a framed or stand-alone dialogue
on subscriber data handling.
4.1 Updating of the VLR in framed operation
If requested by the framing operation, the HLR shall send all stored shared subscriber data to the VLR.
This may be done with one or more messages within a single dialogue.
The VLR shall check the received messages, and:
a) if mandatory data is missing in a message:
- the VLR may immediately reject the message towards the HLR; or
- the VLR may acknowledge the message towards the HLR and wait for further data from the
HLR.
Which of the two options apply is either defined by the protocol specification or is an implementation
option;
b) if unexpected data are received in a message:
- the VLR may reject the message towards the HLR; or
- in case of unexpected data not required in a given context, the VLR may acknowledge the
message towards the HLR and ignore this unexpected data. All other data shall be stored by
the VLR.
Which of the two possibilities apply is an implementation option;
c) if data for unsupported services or features is received:
- the VLR shall respond towards the HLR to the message indicating these features and shall
ignore all received data related to them. All other subscriber data shall be stored;
d) if cases a), b) and c) do not apply for a message, the VLR shall store all subscriber data received.
If during the entire dialogue none of the messages was rejected by the VLR and at termination of the
dialogue no subscriber data are missing, the VLR shall erase all previously stored data and shall store the
data received from the HLR and mark the subscriber data as "confirmed by HLR". Otherwise the
subscriber data shall remain marked as "not confirmed by HLR" (see GSM 03.07).

ETS 300 629 (GSM 03.16 version 4.2.1): November 1996
The HLR shall check all responses from the VLR, and:
a) if a message is rejected, no further updating of the VLR shall occur. The further action on the
framing operation is out of scope of this ETS;
b) if one or more unsupported features are indicated by the VLR, the HLR may:
- store subscriber data including replacement feature(s) locally;
- store and send subscriber data including replacement feature(s);
- ignore this indication.
Which of the three options apply for which feature is out of scope of this ETS;
c) if a message is acknowledged by the VLR, this shall be recognized by the HLR.
The further action on the framing operation after all shared subscriber and replacement data have been
sent (e.g. closing of the dialogue) is out of scope of this ETS.
4.2 Updating of VLR in stand alone operation
If shared subscriber data are added, deleted or changed in the HLR, the HLR shall insert or delete this
subscriber data in the VLR to keep consistency of data stored.
4.2.1 Insertion of data in the VLR
For the insertion of data, the HLR may send one or more messages in a single dialogue.
The VLR shall check the rece
