This command allows the TE to specify a Packet Filter – PF for a Traffic Flow Template – TFT

that is used in the GGSN in UMTS/GPRS and Packet GW in EPS for routing of packets onto different QoS flows towards the TE.

The concept is further described in the 3GPP TS 23.060 [47].

A TFT consists of from one and up to 16  Packet  Filters,  each  identified  by  a  unique  <packet  filter  identifier>.

A  Packet  Filter  also  has an <evaluation precedence index> that is unique within all TFTs associated

with all PDP contexts that are associated with the same PDP address.
