USSD Gateway Service Configuration Screen

Follow these steps to access the USSD Gateway Service Configuration Screen.

  1. From the Service Management System screen, select the Services menu.

  2. Select USSD Gateway > Service Config, or use the Ctrl+R shortcut keys.

Service Trigger

The Service Trigger tab on this screen allows you to set up service triggers. A service trigger is a combination of operator, trigger and gateway. The same trigger can be set against different operators or different gateways giving a different service.

Service Trigger fields

Here is a description of the fields on the Service Trigger tab.

Note: The combination of operator, trigger prefix and gateway must form a unique entry.

Field Description
Operator

The operator this service trigger is set up for.

This field is populated by the USSD Gateway Base Configuration Screen Operator tab.

Trigger

The trigger prefix

This field is populated with the names of all the trigger prefixes created by the USSD Gateway Base Configuration Screen Trigger Prefix tab.

Gateway

The gateway this record belongs to. This field enables multi-Gateway configurations to be deployed across various SLCs. This type of configuration may result in different triggers being configured for the different gateway.

This field is populated by the USSD Gateway Configuration Screen.

Replacement SAN

The code that will be sent in the called party number field of the InitialDP instead of the derived service access number from the trigger prefix. Optional.

If specified, between 1 to 20 hexadecimal digits. These digits will be BCD encoded.
Proxy

Proxy SLEE ID.

Optional. This field should only be populated if the destination service could require a service handover (possibly resulting in a voice call initiation) as this would require the proxy to perform the handover.

Allowed values: Alphanumeric field up to 20 characters in length.

Dest App ID

SLEE ID for the destination application. If the application is on a remote machine, this should contain the address of the local TCRelay application.

Allowed values: Numeric field up to 10 digits in length.

For more information about SLEE IDs, see SLEE Technical Guide.

Note: This field cannot be used with the Dest Service Key field.

Dest Service Key

Service key for the destination application. This service key is placed in the InitialDP used to trigger the application. Required if Dest Service Key is not set.

Allowed values: Alphanumeric field up to 20 characters in length.

Cutoff Timer

The amount of time after a session is started before the USSD GW will end the session and send a message to the handset (corresponds to the status of "Session cut off timer expiry"). Required.

This timer cannot be reset.

Allowed values: Numeric field up to 9 digits in length.

SSF Timer

Time to wait for a response from the service interface or portal. Required.

If no response is received within this period, the session is ended and USSD GW sends the handset a message ( corresponds to the status of "SSF timer expiry"). If a response is received before the timer expires, the timer is stopped.

Allowed values: 1-999999999

Service IF

The service interface triggered by this service trigger.

Dictates the menus that are required for the service.

This field is populated by the Service Interface tab on the USSD Gateway Base Configuration Screen.

Example: For triggers that initiate ACS-Weather control plans, this is must reference the entry in the Service IF tab that has the name of “ACS-Weather”.

Send Flag

Whether ‘*’ or ‘#’ characters should be sent to the service interface for responses to PACUIs.

If set to "Send ‘*’ and ‘#’", the characters will be encoded as BCD ‘c’ and ‘d’ respectively. The terminating ‘#’ character will never be used as a selection character.

This field is populated at startup.
Barring

Contains the following text and database values:

  • “Barring Disabled” – value of 0

  • “Barring IMSI” – value of 1, and

  • “Barring MSISDN” – value of 2.
Fast Access

Indicates whether the “fast access” (also known as dial/type ahead) feature should be enabled for sessions which use this Service Trigger. Fast access causes excess characters to be stored in a buffer and be used as input to subsequent user input requests.

This field is populated when USSD GW is installed. It contains the following options:

  • Fast Access Disabled

  • Always send max

  • With Separators

  • Always send max and current buffer

  • With Separators and current buffer
Deny Access Selecting this check box unconditionally bars all users from the service that meet the trigger criteria.
Prepaid

Enables service interfaces to determine whether the service uses prepaid checking or not.

Allowed values:

  • ticked = prepaid checking is required.
  • clear = prepaid checking is not required.
Forbid Alarm

Specifies whether barred attempts should generate alarms.

This box has two values:

  • Logged
  • Not Logged

Note: For example text for each field, refer to the Find screen in this topic.
