The procedures defined in clause 5.4 apply.

Whenever the PCRF modifies the Authorized QoS of the default bearer, the BBF shall re-evaluate the bearer binding taking into account the default bearer QoS change the default bearer binding indication in the PCC Rule if applicable and any PCC Rule/QoS Rule operation requested by the PCRF.

Annex I (normative):
APN matching procedures

A PCRF or DRA needs to compare APN information received over different interfaces, for instance within the Called-Station-Id AVP, for certain purposes such as session binding. To do so, the PCRF or DRA shall apply the procedures in the present Annex.

The PCRF or DRA shall consider the different possible encoding formats of the APN defined in 3GPP TS 23.003 [37], clause 9.1. When the PCRF or DRA needs to compare an APN only containing the APN Network Identifier, with an APN containing both APN Network Identifier and APN Operator Identifier, the PCRF shall consider those APNs as matching if their APN Network Identifiers match. The PCRF shall perform a case-insensitive comparison for APN Network Identifiers and APN Operator Identifiers.

Annex J (normative):
