Foreword
This 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 identifies the interworking functions and requirements to support Packet Assembly/Disassemby
(PAD) services in the Public Land Mobile Network (PLMN). This ETS corresponds to GSM technical
specification GSM 09.05 version 4.4.2.
The specification from which this ETS has been derived was originally based on CEPT documentation,
hence the presentation of this ETS may not be entirely in accordance with the ETSI/PNE rules.
Reference is made within this ETS to GSM-TSs.
NOTE: TC-SMG has produced documents which give the technical specifications for the
implementation of the European digital cellular telecommunications system. Historically,
these documents have been identified as GSM Technical Specifications (GSM-TSs).
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.

0 SCOPE
The purpose of this Technical Specification (TS) is to identify the interworking functions and requirements
to support PAD services in the PLMN.
GSM 09.05 applies to PAD access in order to provide communications with host systems connected to
PSPDN for MSs.
Within this TS, the requirements for accessing an existing PAD in a PSPDN (basic PAD access) or
accessing a dedicated PAD are considered separately. In each case, the general problem of charging is
examined.
This TS considers only the access by a MS to a PAD and not the reverse access (i.e. only mobile
originated calls are supported).

2 DEFINITIONS AND ABBREVIATIONS
Abbreviations used in this specification are listed in GSM 01.04.
Facility Request The Table 09.05/7 (given in Annex 4), extracted from CCITT Rec. X.28 lists the
facility request/indication codes.
Note: The facility " closed user group " is not part of the dedicated PAD access.
3 Circuit switched access to a PAD in the PSPDN (Basic PAD access)
3.1 General
The basic PAD access is the access to a X.28 dial in port in a PSPDN without or via one or more transit
ISDN or PSTN networks. This access is provided by GSM bearer services 21 - 26. However, it should be
noted that the X.28 PAD does not support out-band flow control and does not support 7 bit characters
without parity. The general interworking requirements are defined in GSM 09.07.
Note: In cases where no transit networks are used, the interface between the PLMN and the
PAD is outside the scope of this TS and implementation dependent.

3.2 Home PAD access
Home PAD access would normally be available for a mobile subscriber both when he/she is present in the
home PLMN and when in a visited PLMN. Figure 09.05/1 illustrates both of these examples where he/she
is accessing a PAD via the home PSTN. To access the PAD the user would need to be registered with the
PSPDN and have his/her own NUI if a specific profile or local charging are required.
In this instance to initiate a call to the PAD the mobile subscriber sets up a call to the PSTN number
associated with the PAD. The interworking function provides only the necessary modem, RLP (if required)
etc., as indicated in the call set-up message and does not provide any additional functionality associated
with PAD access. This access being available to the mobile subscriber from the home PLMN implies the
use of a national PSTN call and when in a foreign PLMN the use of an international PSTN call.

3.3 Visited PAD access
When the mobile subscriber is within a PLMN in a foreign country an alternative to home PAD access is
given in Figure 09.05/2. The PAD used in this case is a PAD within the visited country.
In this case the mobile subscriber initiates a PSTN call to the PAD in the visited country, and utilises the
international link within the PSPDN.
The mobile subscriber would need to be registered with the visited PSPDN to obtain an NUI if a specific
profile or local charging are required, plus needing to know the correct PSTN number for accessing the
PAD. The mobile subscriber would also need to know the user procedure for connecting to the PAD
including the presentation of the NUA (international/national). Again the interworking function would not
provide any additional requirements over and above the normal PSTN interworking.

4 Dedicated PAD access
4.1 Definition
The "dedicated PAD access" provides the shortest possible connection from the PLMN to a PAD for both
home subscribers staying in the home PLMN as well as roaming foreign subscribers in the visited PLMN.
The MT or TA does not use the E.164 address of the PAD. A common access procedure as described
below being applied by all PLMNs supporting this type of service hides the differences of existing PADs in
GSM countries for GSM PLMN subscribers.
The mobile subscriber has only a subscription to his home PLMN for the use of the "dedicated PAD
access". The applicable GSM bearer services are those of the 40-series.
The dedicated PAD provides general PAD functions according to CCITT Rec. X.3, X.28 and X.29 and in
addition PLMN specific functions (e.g. identification, profile selection) as defined in this specification.
In this type of PAD access, the PLMN has direct access to a PAD e.g dedicated link, etc. In this TS there
is no difference between a PAD which has all its entry ports connected to the PLMN and a PAD which has
only some entry ports dedicated to the PLMN.
For roaming subscribers, the user accesses a dedicated PAD of the visited PLMN, in that respect GSM
09.05 does not allow access to the dedicated PAD within the home PLMN. In this case only figure 09.05/2
is valid.
In this case, the PAD is either an existing one or one which is provided by the PLMN. It is a network
operator option as to which should be provided. When the PAD is restricted solely to PLMN use then it is
defined as a GSM variant PAD.
Charging procedures are covered in section 4.8. It is this type of PAD access and the procedures
necessary to invoke it that will be discussed in the rest of this section.
It is a network operators option as to whether basic or basic and dedicated PAD access should be
provided .
