Invocation parameters

. ss-UserData

This parameter is analysed in the HLR to see whether the USSD is
to be handled locally, or forwarded to the gsmSCF.

Result parameters

. ss-UserData

If the result message is received from the gsmSCF and is to be
forwarded towards the VLR, the content of ss-UserData is not
checked by the HLR.

If the USSD was handled locally in the HLR, the string content
depends on the functionality which is done as the result of the USSD
string analysis.

Error causes

If an error cause is received from the gsmSCF, it is forwarded to the VLR.

The possible error causes are:

. SystemFailure

This error cause is sent by the HLR to the VLR, if the subscriber has
the Mobile Initiated USSD barring service active.

. UnexpectedDataValue

3.2.5.8 ProcessUnstructuredSS-Request

This operation is implemented in version 2 dialogues only. In version 1
ProcessUnstructuredSS-Data is used.

This operation is received from the VLR and forwarded to gsmSCF. If the
gsmSCF-interface is not in use (if the feature is not activated), the HLR
aborts the dialogue indicating that the Application Context is not
supported.

As an optional feature, based on a subscriber specific indicator only phase
1 USSDs are accepted, in which case the HLR aborts the version 2
dialogue indicating that the Application Context is not supported, and that
only version 1 is supported.

As an optional feature (Features 1545 and 1576: Sequential and Parallel
Alerting), the USSD is handled in the HLR, for ringing group interrogation
or modification.

As an optional feature (Feature 1609: Follow Me), the USSD is forwarded
to another HLR, which handles the USSD and responds to it.

. Operation timer: 10 minutes

. Re-attempts in case procedure fails: not used

. SCCP address: GT, gsmSCF's address as a result of the USSD
string analysis

If the result of the USSD string analysis gives a routing address, the
destination subsystem number is also received from the analysis
result (if not specified in the analysis result, the default value is 5).

When the USSD is forwarded from HLRa to HLRb, because of the
Feature 1609: Follow Me, the MSISDN of the subscriber in HLRb is
used as the Global Title. In that case the Subsystem Number 6
(HLR) is used in both the Called Party Address and the Calling Party
Address.

Invocation parameters

. ussd-DataCodingScheme

This parameter is used for decoding the ussd-String to make the
USSD string analysis in the HLR.

Supported coding schemes are:
. 7 bit coding, ussd-DataCodingScheme values (hexadecimal):

00..0F, 10, 40..43, 50..53, F0..F3
. 8 bit coding (normal ASCII), ussd-DataCodingScheme values

(hexadecimal): 44..47, 54..57, F4..F7
. 16 bit coding, ussd-DataCodingScheme values (hexadecimal):

11, 48..4B, 58..5B. Characters 0000..007E with this coding
scheme are supported

. ussd-String

This parameter is analysed in the HLR to see whether the USSD is
to be handled locally, or forwarded to the gsmSCF.

Due to limitations on the underlying layers (MTP, SCCP and TCAP),
the maximum feasible length of the ussd-String in
ProcessUnstructuredSS-Request argument is 134 bytes. Otherwise
the overall MTP message length may exceed the limit of 272 bytes,
