1 Scope
Existing systems have largely standardised the complete sets of bearer services, teleservices and supplementary services
which they provide. 3GPP specifications specify service capabilities rather than services, allowing service
differentiation and system continuity. This Technical Specification (TS) describes how and what kind of services the
user has access to.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of this TS, the following definitions apply:
Basic telecommunication service : this term is used as a common reference to both bearer services and teleservices.
Bearer service : is a type of telecommunication service that provides the capability of transmission of signals between
access points.
Call : a logical association between several users (this could be connection oriented or connection less).
Connection : is a communication channel between two or more end-points (e.g. terminal, server etc.).
Mobile termination : the mobile termination is the component of the user equipment which supports functions specific
to management of the radio interface (Um).
Multimedia service : Multimedia services are services that handle several types of media. For some services,
synchronisation between the media is necessary (e.g. synchronised audio and video). A multimedia service may involve
multiple parties, multiple connections, and the addition or deletion of resources and users within a single call.
Nomadic Operating Mode : Mode of operation where the terminal is transportable but being operated while stationary
and may in addition require user co-operation (e.g. close to open spaces, antenna setup.).
Quality of Service : the collective effect of service performances which determine the degree of satisfaction of a user
of a service. It is characterised by the combined aspects of performance factors applicable to all services, such as;
service operability performance;
- service accessibility performance;
- service retention performance;
- service integrity performance; and
- other factors specific to each service.
Service Capabilities: Bearers defined by parameters, and/or mechanisms needed to realise services. These are within
networks and under network control.
Service Capability Feature: Functionality offered by service capabilities that are accessible via the standardised
application interface
Services: Services are made up of different service capability features.
Supplementary service : is a service which modifies or supplements a basic telecommunication service. Consequently,
it cannot be offered to a user as a standalone service. It shall be offered together with or in association with a basic
telecommunication service. The same supplementary service may be common to a number of basic telecommunication
services.
Teleservice; is a type of telecommunication service that provides the complete capability, including terminal equipment
functions, for communication between users according to standardised protocols and transmission capabilities
established by agreement between operators.

4 Framework for the description of telecommunication
services and applications
4.1 General
Telecommunication services defined by 3GPP specifications are the communication capabilities made available to users
by home environment and serving network. A PLMN provides, in co-operation with other networks, a set of network
capabilities which are defined by standardised protocols and functions and enable telecommunication services to be
offered to users.
A service provision by a HE/SN to a user may cover the whole or only part of the means required to fully support the
service.
The service classification and description which follow are independent of different possible arrangements for the
ownership and provision to the user of the means required to support a service.

4.2 Basic telecommunication services
Basic telecommunication services are divided in two broad categories;
- bearer services, which are telecommunication services providing the capability of transmission of signals
between access points;
- teleservices, which are telecommunication services providing the complete capability, including terminal
equipment functions, for communication between users according to protocols established by agreement
between network operators.
The communication link between the access points may consist of PLMN, one or more transit networks and a
terminating network. The networks between the two access points typically use different means for bearer control.
Figure 1 illustrates these definitions.

4.2.1 Bearer services
The characterisation of a bearer service is made by using a set of characteristics that distinguishes it from other bearer
services. Particular values are assigned to each characteristic when a given bearer service is described and defined.
The service characteristics as they apply at a given reference point where the user accesses the bearer service.
In the general case networks between the two access points use different control mechanisms. In this case the bearer
services of each network throughout the communication link have to be translated at the network interfaces to realize an
end to end bearer service.
A list of definitions of attributes and values used for bearer services is contained in clause 5.
The bearer services are negotiable and can be used flexibly by applications.

4.2.2 Teleservices
Section 6 defines both standardised and non-standardised teleservices. Some teleservices are standardised because that
interworking with other systems have been recognised as a requirement. Other teleservices will not be standardised. A
decoupling between lower layer (i.e. bearer attributes) and higher layer capabilities will be necessary for the
development of teleservices.
4.3 Supplementary services
A supplementary service modifies or supplements a basic telecommunication service. Consequently, it cannot be
offered to a user as a stand alone service. It shall be offered together or in association with a basic telecommunication
service. The same supplementary service may be applicable to a number of basic telecommunication services.
Two methods are used for the characterisation of supplementary services;
- The first method is used for the description of existing standardised supplementary services. These services are
specified through the detailing of each of the operations involved in service provision and service usage (the
provision/withdrawal, registration/erasure, activation/deactivation, invocation and interrogation operations).
Clause 7 lists these services.
- The second method enables the provision of HE/SN specific supplementary services. To make this possible,
services can be built using service capability features which are accessed via the standardised application
interface.
A PLMN shall be able to handle multiple supplementary services within a call. Interactions shall be handled when
several supplementary services are activated in the same call. When multiple supplementary services can be activated
concurrently, some prioritisation of the services will be necessary. Certain services may override or deactivate other
services.
Interactions between operator specific supplementary services are not defined.
The following issues need consideration when interactions between services occur;
- Different phases of a call.
- A service spanning on more than one network.
- Service interactions that may occur between services offered to a single user, as well as between services offered
to different interacting users.
NOTE: The methods defined for characterisation of services are description methods. They do not imply or
restrict different implementations.
4.4 Service Capabilities
Service capabilities are based on functionality and mechanisms/toolkits such as provided by SAT [5], MExE [6], IN and
CAMEL [8]. These service capabilities can be made visible to the applications through an application interface. See
clause 8 for service capability features.

5 Bearer Services
5.1 Definition of bearer services
Bearer services provide the capability for information transfer between access points and involve only low layer
functions. These functions are sometimes referred as low layer capabilities (in reference to OSI layers). The user may
choose any set of high layer protocols for his communication and the PLMN does not ascertain compatibility at these
layers between users.
In the general case a communication link between access points provides a general service for information transport.
The communication link may span over different networks such as Internet, Intranets, LANs and ATM based transit
networks, having network specific means for bearer control. Each network contributes to the end-to-end QoS perceived
by the end-user.
PS and CS domains provide a specific set of bearer capabilities. The Circuit bearer services are described in 22.002 [2].
The packet services (GPRS) is described in 3GPP TS 22.060 [7]. Following chapters describe the overall requirements
for both the CS and PS domain bearers and also for the bearers used by teleservices.
5.2 Description of bearer services
Bearer services are characterised by a set of end-to-end characteristics with requirements on QoS. The characteristics
and requirements shall cover major network scenarios, i.e. the cases when the terminating network is PSTN, ISDN, IP
networks/LANs, X.25 and a PLMN.
Quality of Service is the quality of a requested service (Teleservice or Bearer Service or any other service, e.g. customer
care) as perceived by the customer (ITU-T Recommendation E.800 [18]). QoS is always meant end-to-end. Network
