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 specifies the procedures used at the radio interface (reference point Um as defined in ETS 300
551) for normal operation, registration, erasure, activation, deactivation, interrogation and network
invocation of call offering supplementary services within the European digital cellular telecommunications
system (Phase 2).
This ETS corresponds to GSM technical specification, GSM 04.90 version 4.1.1.
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 Technical Specifications (GSM-TS) (NOTE).
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-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.

1 Scope
This technical specification gives the stage 3 description of the unstructured supplementary service data
(USSD) operations.
The group of unstructured supplementary service data operations is divided into two different classes:
- Network initiated unstructured supplementary service data operations (section 5);
- Mobile initiated unstructured supplementary service data operations (section 6).
2 Normative references
This ETS incorporates by dated and undated reference, provisions from other publications. These
normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this ETS only when incorporated in it by amendment or revision. For undated references, the
latest edition of the publication referred to applies.
[1] GSM 01.04 (ETR 100): "European digital cellular telecommunications system
(Phase 2); "Abbreviations and acronyms".
[2] GSM 04.08 (ETS 300 557): "European digital cellular telecommunications
system (Phase 2); Mobile radio interface layer 3 specification".
[3] GSM 04.80 (ETS 300 564): "European digital cellular telecommunications
system (Phase 2); Mobile radio interface layer 3 supplementary services
specification Formats and coding".
3 Definitions and abbreviations
Abbreviations used in this specification are listed in GSM 01.04.
4 Cross phase compatibility
For the mobile initiated USSD operations, a number of changes exist between this specification and the
protocol version 1 specification. For these operations the main body of this specification assumes that all
network entities comply with this version of the service. In this case an additional sub-section defines the
additional requirements for when one or more network entities or the MS complies with the protocol
version 1 specifications for the USSD operations.

5 Network initiated unstructured supplementary service data operations
5.1 Unstructured supplementary service data request
5.1.1 Normal operation
The network invokes an USSD request by sending a REGISTER message containing a UnstructuredSS-
Request invoke component to the mobile station.
The mobile station shall respond to the request by sending a FACILITY message containing the user's
mobile subscriber's response in a return result component. The network shall pass the data received in
the response to the application handling USSD operations and shall wait for the response of the
application. The application may either continue or terminate the dialogue.
When the application continues the dialogue, it may initiate another USSD operation by sending a
FACILITY message (see figure 5.2). The operation may either be an USSD request or notification (see
section 5.1.2).
When the application terminates the dialogue, the network shall clear the transaction by sending a
RELEASE COMPLETE message. The mobile station may also clear the transaction at any time by
sending a RELEASE COMPLETE message upon the request of the user.
If the mobile station is unable to process the request received from the network, it shall return an error
indication by sending a FACILITY message containing a return error component. Error values are
specified in TS GSM 04.80.
When the mobile station receives an USSD operation in parallel to any call independent supplementary
service transaction, it shall respond with a return error component in a RELEASE COMPLETE message,
containing the "USSD-Busy" error as specified in TS GSM 04.80, to indicate the failure in handling a
parallel USSD operation. However, the network is allowed to initiate USSD operations in parallel to call
related transactions.
