XID parameters

[Josh toal]

Hi

regarding qos I have seen in a book title "GPRS in practice a companion to
the specifications"

In chapter 11 it says " If the network layer does not like the allocated
QoS profile, it can terminate the session",, may be you are right.

I am not able to understand why after MS doing pdp activation accept  it
deactivate the pdp context.

Can somebody point out some potential reasons.

regards
Josh
