3gpp.ini File

NOTE: You can enable 3GPP and 3GPP2 simultaneously. 3GPP support is enabled by configuring the 3gpp.ini file, and is supported with the Steel-Belted Radius Carrier core license. 3GPP2 support is available only with the optional CDMA mobility module license. To enable deployment in mixed 3GPP2/WiMAX environments, Steel-Belted Radius Carrier uses the mip.ini file. 3GPP is implicitly last in the mip.ini list, and is not specified in the mip.ini file, since it is not a mobility module. Each mobility module (CDMA and WiMAX) listed in the mip.ini file gets a chance at servicing the incoming message. If the message is for that module, then the module services it. If a module decides that the message is not intended for itself, it hands the message to the next module listed in the mip.ini file. If none of the listed mobility modules service the message, and if 3GPP is enabled, then 3GPP gets a chance to service the message. Of course, each of the mobility modules needs to be enabled in order to examine and possibly service the request.

The 3gpp.ini file, contains the settings for 3GPP support and consists of the following fixed sections:

Table 120: 3gpp.ini Sections 

Sections	Description
[Settings]	Enables or disables 3GPP processing.
[Attributes]	Identifies dictionary attributes necessary for request processing.

[Settings] Section

The [Settings] section (Table 121) contains the master switch that enables the 3GPP feature set:

Table 121: [Settings] Sections 

Setting	Description
Enable	Setting this field to 1 enables 3GPP support. Setting this field to 0 disables 3GPP support.

Example

[Settings]

Enable = 1

[Attributes] Section

The [Attributes] section (Table 122) specifies the two attribute names that are used by Steel-Belted Radius Carrier when processing special accounting requests for 3GPP mobile sessions and resource management.

Table 122: [Attributes] Sections 

Setting	Description
Session-Stop- Indicator	Specifies the name of the attribute that Steel-Belted Radius Carrier expects in Accounting Stop requests when the 3GPP mobile session is to be deleted (closed).
NSAPI	Specifies the name of the attribute that Steel-Belted Radius Carrier uses in conjunction with the username to facilitate the identification of different 3GPP mobile sessions for the same user on a single GGSN. In the absence of an NSAPI, Steel-Belted Radius Carrier uses the contents of the User-Name attribute as the matching key.

Example

[Attributes]

Session-Stop-Indicator = 3GPP-Session-Stop-Indicator

NSAPI = 3GPP-NSAPI

The radius.dct file shipped with Steel-Belted Radius Carrier has been configured with the attributes necessary for supporting 3GPP mobile sessions in compliance with the 3GPP standards.

NOTE: Use the default settings in this section unless your GGSN vendor specifies different settings.
