▀ Enhanced Features and Functionality
For x-header insertion, there should either be a post-processing rule whose charging-action gives no disposition-action
or the packet should not match any of the post-processing rules so that the disposition action obtained from charging-
rule matching is applied.

Tethering Detection

This section provides an overview of the Tethering Detection feature.
Important:
Tethering refers to the use of a mobile smartphone as a USB dongle/modem to provide Internet connectivity to PC
devices (laptops, PDAs, tablets, and so on) running on the smaprtphone's data plan. Typically, for smartphone users,
most operators have in place an unlimited data plan, the usage of which is intended to be from the smartphone as a
mobile device. However, some subscribers use the low cost / unlimited usage data plan to provide Internet connectivity
to their laptops in places where normal Internet connection via broadband/WiFi may be costly, unavailable, or insecure.
The Tethering Detection feature enables detection of subscriber data traffic originating from PC devices tethered to
mobile smartphones, and also provides effective reporting to enable service providers take business decisions on how to
manage such usage and to bill subscribers accordingly.
Important:
The Tethering Detection feature is enabled on a per rulebase basis. The rulebase (billing plan) assigned for APN will
contain the tethering detection related configuration. ECS performs tethering detection on a per flow basis for all
subscribers (for whom TAC database match succeeded) using an APN in which the feature is enabled. The extent to
which the detection mechanism is executed depends on the type of flow. If it is a non-TCP flow, for example UDP or
ICMP, then tethering detection is not possible for the same.

License Requirements

Tethering Detection is a licensed Cisco feature. A separate feature license may be required. Contact your Cisco 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.

MUR Support for Tethering Detection

The ASR chassis works in conjunction with the Mobility Unified Reporting (MUR) application to facilitate tethering
detection on the chassis.
If MUR is not deployed, then the database file must be manually placed on the ASR chassis, in the
raid/databases/
For more information on MUR, refer the MUR Online Help System and the Mobility Unified Reporting System
Installation and Administration Guide.
