MME/SGSN Topology Hiding Configuration Sets

MME/SGSN Topology Hiding Configuration Sets provide information that is used to perform MME/SGSN Topology Hiding for Protected Networks.

Each Protected Network can reference a single MME/SGSN Topology Hiding Configuration Set.

The fields are described in Diameter MME/SGSN Topology Hiding Configuration Set elements.

Each MME/SGSN Topology Hiding Configuration Set contains the following information:

• MME/SGSN Topology Hiding Configuration Set Name - Unique name for this Configuration Set.
• Pseudo Hostname Generation - Attributes to control the format and generation of Pseudo Hostnames corresponding to an Actual Hostname.
  • Count - The maximum number of Pseudo Hostnames associated with an Actual Hostname.
  • Randomize Count - Allows random number of Pseudo Hostnames between 1 and Count to be associated with an Actual Hostname.
  • Auto Generate - Allows Pseudo Hostnames to be automatically generated corresponding to an Actual Hostname.
  • Prefix - Prefix for the auto-generated Pseudo Hostname.
  • Suffix - Suffix for the auto-generated Pseudo Hostname.
  • Length - Length of the random number used in the auto-generated Pseudo Hostname.
• Hostnames - List of Actual Hostnames and their Pseudo Hostnames in this MME/SGSN Topology Hiding Configuration Set.
• MME/SGSN Actual Hostname Not Found Action - Action to be taken when the Orig-Host in the Diameter message is not configured as Actual Hostname.
• MME/SGSN Actual Hostname Not Found Answer Result-Code Value - Value to be placed in the Result-Code AVP of the Answer message.
• MME/SGSN Actual Hostname Not Found Vendor Id - Value to be placed in the Vendor ID AVP.
• MME/SGSN Actual Hostname Not Found Answer Error Message - String to be placed in the Error-Message AVP of the Answer message.

On the Diameter > Configuration > Topology Hiding > MME/SGSN Topology Hiding Configuration Sets page, you can perform the following actions:

• Filter the list of MME/SGSN Topology Hiding Configuration Sets to display only the desired MME/SGSN Topology Hiding Configuration Sets.
• Sort the list by column contents in ascending or descending order (except Hostname Suffixes), by clicking the column heading. The default order is by MME/SGSN Topology Hiding Configuration Set Name in ascending ASCII order.
• Click Insert.

  You can add a new MME/SGSN Topology Hiding Configuration Set and its elements. See Adding an MME/SGSN Topology Hiding Configuration Set.

  If the maximum number of MME/SGSN Topology Hiding Configuration Sets (500) already exist in the system, the Diameter > Configuration > Topology Hiding > MME/SGSN Topology Hiding Configuration Sets [Insert] page does not open, and an error message displays.

• Select a MME/SGSN Topology Hiding Configuration Set Name in the list and click Edit.

  You can edit the selected Configuration Set. See Editing an MME/SGSN Topology Hiding Configuration Set.

• Select an MME/SGSN Topology Hiding Configuration Set Name in the list and click Delete to remove the selected MME/SGSN Topology Hiding Configuration Set. See Deleting an MME/SGSN Topology Hiding Configuration Set.

  If at least one Protected Network references the selected MME/SGSN Topology Hiding Configuration Set, then the Configuration Set is not deleted.
