In this release, P-GW supports Mobility Hotspot (MHS) usage on RADIUS accounting.	21.23

Feature Description

In RADIUS Accounting, the subscriber data usage is monitored using the Type Length Values (TLV) namely Acct-Input-Octets and Acct-Output-Octets to receive a cumulative data usage report. In this StarOS 21.23 release, to identify Data usage differentiation effectively in RADIUS accounting for 4G Mobile Hotspot (MHS) data usage, 5G MHS data usage, and 5G composite data usage the following new TLVs are introduced:

4G_MHS_Acct_Input_Octets
4G_MHS_Acct_Output_Octets
5G_MHS_Acct_Input_Octets
5G_MHS_Acct_Output_Octets
5G_Comp_Acct_Input_Octets
5G_Comp_Acct_Output_Octets

RADIUS interim and stop messages report MHS data usage . MHS data usage reporting is allowed per bearer. These TLVs comprises of the cumulative values from the previous interim messages and raw bytes.

When MHS data usage reporting is dynamically enabled or disabled, the change takes effect only for the new calls.

Note

Only EUTRAN and NB_IOT Radio Access Technology (RAT) types are supported for MHS data usage reporting.

The PRA IDs that are configured in a PRA profile which are associated with APN level are used to identify 5G data usage.

Relationship with Other Features

This feature is related to Smartphone Tethering Detection Support feature. For more information about Smartphone Tethering Detection support, refer the PDN Gateway Overview chapter in the P-GW Administration Guide.

License Requirements

The Mobile Hotspot usage on RADIUS Accounting feature requires enabling of Tethering Detection License. Contact your account representative for detailed information on specific licensing requirements. For information on installing and verifying licenses, refer to the Managing License Keys section of the Software Management Operations chapter in the System Administration Guide.

Limitations

The following is the known limitations of the feature:

The MHS supports only dictionary custom76.

Configuring MHS Usage on RADIUS Accounting

This section provides information on configuring MHS Usage on RADIUS accounting.

Configuring PRA Profiles

Use the following command to configure PRA profiles to differentiate traffic.

configure 
            context context_name 
               pra-profile pra_profile_name  
                [ no ] pra-id pra_id_value traffic-map-type type_value  
            end

NOTES:

pra-profile : Configures PRA profiles to differentiate traffic.
pra-id : Configures the PRA ID.
no : Removes the PRA ID.
traffic-map-type : Configures the traffic map type.
type_value : Enter enum values - 5G.

NOTES:

A maximum of three PRA IDs per PRA list and associate PRA list in APN level are allowed to differentiate 5G traffic.

Associating PRA Profiles at APN Level

Use the following CLI commands to associate PRA profiles at APN level:


configure 
  context context_name 
    apn apn_name 
      [ no ] pra-profile profile_value 
 exit

NOTES:

apn : Configures the APN.
pra-profile : Associates PRA profiles at APN level.
no : Removes PRA profiles at APN level.

Configuring AAA Group

Use the following commands to configure AAA Group for the newly-added TLVs to send RADIUS Accounting messages.

configure 
            context context_name 
              aaa group group_name 
                [ no ] radius accounting mhs-traffic enable 
                radius dictionary custom76 
            end

NOTES:

mhs-traffic : Specifies MHS data usage reporting.
enable : Enables MHS data usage reporting.
no : Disables MHS data usage reporting.
