The BSS shall not negotiate BSS PFCs for the following pre-defined PFI values: Best Effort, Signaling, and SMS.

PFIs have local significance to a mobile station. A BSS Packet Flow Context shall be uniquely identified by the PFI along with the IMSI or TLLI within a routeing area.

11.3.43 Aggregate BSS QoS Profile

This information element indicates the Aggregate BSS QoS Profile (ABQP) for a BSS Packet Flow Context. The ABQP is considered to be a single parameter with multiple data transfer attributes as defined in 3GPP TS 23.107.

Timer value: Bits 5 to 1 represent the binary coded timer value.

Unit value: Bits 6 to 8 defines the timer value unit for the GPRS timer as follows:

Bits

0 0 0 value is incremented in multiples of 2 seconds

0 0 1 value is incremented in multiples of 1 minute

0 1 0 value is incremented in multiples of decihours

1 1 1 value indicates that the timer does not expire.

Other values shall be interpreted as multiples of 1 minute in this version of the protocol.
