Location Based Local-Policy Rule Enforcement
CSCuy77896 - Location Based Local Policy Rule enforcement
Applicable Products: P-GW, SAEGW
Feature Changes
This feature is introduced to activate different predefined rules for different E-UTRAN Cell Global Identifiers
(ECGIs) when the subscriber is connected to a corporate APN. The subscriber has to explicitly bring down
the connection with the corporate APN and re-establish session with Internet APN when out of the company
area. It is assumed that corporate APN does not use PCRF and use only Local-Policy. In this case, all calls
matching the APN is directed to the Local-Policy.

For this feature to work, the license to activate Local-Policy must be configured. For more information

Important
To activate different predefined rules for ECGI, Local-Policy configurations are enhanced to support:
• Configuration and validation of a set of ECGIs
• Installation of ECGI_CHANGE event trigger through Change Reporting Action (CRA) event
• Detection of ECGI_CHANGE event
This feature supports the following actions to be applied based on the ECGI match with Local-Policy ruledef
condition:
condition:
• Enable a redirect rule on ECGI_CHANGE event notification when the ECGI belongs to a certain group
• Enable a wild card rule for any other ECGIs
This feature has a dependency on TAI and ECGI Change Reporting feature, which provides a framework to
report ECGI-Change from session manager module to IMSA/Local-Policy module.
report ECGI-Change from session manager module to IMSA/Local-Policy module.
Limitations
This section identifies the known limitations of this feature.
• ECGI Change detection and triggering is a pre-requisite for this feature.
• This feature is supported for Local-Policy-only (lp-only) mode wherein, all requests and responses within
a particular APN directly go to Local-Policy without contacting PCRF. That is, this feature does not
work in Local policy fallback mode and dual mode wherein both PCRF and Local-Policy co-exist.
