1 Framework for the description of telecommunication
services
1.1 The attribute method of characterization of circuit
telecommunication services
This characterization is made by using a set of attributes. A telecommunication service attribute is a specific
characteristic of that service whole values distinguish it from other telecommunication services. Particular values are
assigned to each attribute when a given telecommunication service is described and defined.
A list of definitions of attributes and values used for bearer services and teleservices is contained in, respectively,
annex A and annex B.
2 Description of circuit telecommunication services by
the attribute method
2.1 General
Telecommunication services are described by attributes which define service characteristics as they apply at a given
reference point where the customer accesses the service. The description of a telecommunication service by the method
of attributes is composed of:
- technical attributes as seen by the customer; and
- other attributes associated with the service provision, e.g. operational and commercial attributes.
2.2 Categorisation of telecommunication services
The concepts introduced in the present document are illustrated in table1.

3 Characterization of circuit telecommunication
services
3.1 General
A telecommunication service supported by a PLMN is characterized and described by service attributes.
There are two groups of service attributes applicable to user information flow:
- low layer attributes;
- high layer attributes.
ETSI
3GPP TS 22.001 version 13.0.0 Release 13 8 ETSI TS 122 001 V13.0.0 (2016-02)
Bearer services are characterized only by low layer attributes. Teleservices are characterized by both low layer
attributes and high layer attributes.
The basic characteristics of a telecommunication service are described by the basic service attributes.
The additional characteristics associated with a supplementary service which modify or supplement a basic
telecommunication service are described in Specification 3GPP TS 22.004 [7].
3.2 Bearer services
Bearer services are characterized by a set of low layer attributes in Specification 3GPP TS 22.002[5]. These attributes
are classified into four categories:
- information transfer attributes;
- access attributes;
- interworking attributes;
- general attributes, including operational and commercial attributes.
The bearer capability defines the technical features of a bearer service as they appear to the user at the appropriate
access point. For the time being, the bearer capability is characterized by information transfer, access and interworking
attributes. A bearer capability is associated with every bearer service.
3.3 Teleservices
Circuit teleservices provide the full capacity for communication by means of terminals and network functions and
possibly functions provided by dedicated centres.
Circuit teleservices are specified in 3GPP TS 22.003 [6]. Teleservices are characterized by a set of low layer attributes,
a set of high layer attributes and operational and commercial attributes.
Low layer attributes are those used to characterize the bearer capability. High layer attributes are used in Specification
3GPP TS 22.003 [6] to describe high layer (i.e. layer 4-7) information transfer related characteristics. They refer to
functions and protocols of layers 4-7 in the ITU-T Recommendation X.200 framework which are concerned with the
transfer, storage and processing of user messages (provided by a subscriber's terminal, a retrieval centre or a network
service centre).
Therefore, not all attributes can be applied directly at the user to terminal interface as they represent two kinds of
features, the bearer capability and the terminal features, that are not directly perceived by the user.
4 Provision of telecommunication services
Specifications 3GPP TS 22.101[4] and 3GPP TS 22.011 [13] define some aspects of the provisions of
telecommunication services by a 3GPP system.
The provision of telecommunication services implies:
- subscription of basic services and possibly subscription to supplementary services;
- registration into a service directory;
- compatibility between terminals;
- interworking capabilities (see 3GPP TS 29 series of specifications).
The user's subscription to a Basic or Supplementary service is normally verified by the network prior to completion of
Call Establishment and/or Supplementary Service operation. This subscription checking shall be performed in
accordance with the following subclauses.
ETSI
3GPP TS 22.001 version 13.0.0 Release 13 9 ETSI TS 122 001 V13.0.0 (2016-02)
4.1 Subscription checking for Basic Services
General
Subscription checking is the function/process to ascertaining whether a subscriber has the authorization to use the
particular Basic Service deduced from the call set-up parameters. It is the responsibility of the HPLMN to transfer, to
the VPLMN, only the subscription data corresponding to those services a given subscriber is entitled to use in that
VPLMN.
For mobile originated calls, subscription checking is performed in the VLR, whilst for mobile terminated calls it is
performed in either the HLR or the VLR (determined as described below). The prerequisite for executing the
subscription check is a successful deduction of a Basic Service from the Compatibility Information contained in the call
set up, i.e. Bearer Capability Information Element and, in some cases, also the Low Layer and High Layer
Compatibility Information elements.
For mobile originated calls an UE shall indicate the requested service by appropriate compatibility information elements
according to 3GPP TS 27.001 [8]. This information is mapped to an individual Basic Service code (i.e. the MAP
representation) by the MSC in order to be compared with the subscriber data available in the VLR.
An equivalent process is required in the HLR for mobile terminated calls, where the caller's requested service is
indicated to the HLR (by the ISDN) by exhaustive compatibility information consisting of ISDN Bearer Capability
Information Elements and in some cases - depending on the service requested - also of Low Layer and High layer
Compatibility information elements. In case the compatibility information is not exhaustive, e.g. when the call is
originated/transited by a PSTN, no Basic Service can be deduced and subscription checking cannot be performed in the
"normal" way. Instead, rules for the Single and Multi Numbering Schemes apply.
In the Multi Numbering Scheme the Basic Service can be deduced by information stored in the HLR against the called
number and hence an implicit subscription check is performed. In the Single Numbering Scheme, the Basic Service
cannot be deduced until the UE has responded to the set up and therefore the HLR cannot perform subscription check.
Instead, the VLR/MSC will perform the subscription check or calls are passed "unfiltered" (as regards subscription
check), at the network operators' discretion.
Bearer Services
3GPP TS 22.002 [5] lists the Bearer Services, each of them with a specific "BS number". Single services defined
independent of the fixed network user rate are called General Bearer Services. These distinct [numbered] services may
individually be provided to a subscriber. Whichever the subscription arrangements are, all PLMNs (MSCs, VLRs and
HLRs) shall be able to allow - as regards subscription checking - the use of individually subscribed-to Basic Services,
within the range of services supported by the PLMN. That is, whenever it is possible to deduce the Basic Service from a
call set up, subscription check shall be performed at the granularity of that particular Basic Service or the group to
which it belongs.
TeleServices
3GPP TS 22.003 [6] lists the TeleServices, each of them with a specific "TS number". These may be provided to
subscribers individually or combined, to the operators' discretion, however TS 12 (Emergency calls) and TS 23 (CBS)
are not subscribable. But, as for Bearer Services, networks shall be able to handle subscription checking at the
granularity of individual TeleServices.
Table 2 summarizes the basis on which a successful subscription checking will result. It also describes on which basis
Supplementary Service handling for a given call set-up should be performed.

- SS handling: Against which VLR or HLR data SS handling should be performed. For example; a
call set-up indicating BS61 and Asynchronous mode should be treated for SS purposes in
accordance with the SS-data stored against BS group 2x.

When TS61 is requested in a call set-up and the subscription check for TS61 is negative, but a subscription check for
TS62 is positive, then the call shall proceed according to the TS 22.003 [6]and TS 27.001 [8]. If a subscription check
for both TS61 and TS62 is negative, then the call shall be released.
4.2 Subscription checking for Supplementary Services
This is described in 3GPP TS 22.004 [7].
