Hi All
As per the specs after PDP context accept mobile station should exchange
XID parameters with SGSN. before it initiate transfer of data.
As per the literature mobile station if not happy with the negotiated
quality of service it will send the deactivation request and I am getting
the same.
Is this is the only reason mobile station will send deactivation request or
something else, which I am missing.
Any suggestion to fix this problem.
can anybody comment on this please.
regards
Josh

Hello,
I think there is a confusion here.
The MS if it is not happy with the QoS will send a PDP modification request to change it
or to change the traffic flow template. This can also be initiated by the network.
A PDP context deactivation is used for deleting/removing a PDP context. There are 3 cases
when this can happen and can also be initiated by MS or the network:
a) GPRS detach
b) remove subscriber data
c) application deactivation
Maybe someone else can explain it better.
Regards,
R.

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
