New issue 221 by [email protected]: Tssf timer for CAP stack
http://code.google.com/p/jss7/issues/detail?id=221
We need to introduce a Tssf timer into a CAP stack.
From CAP specification:
A timeout has occurred in the gsmSSF, gprsSSF, smsSSF or assisting gsmSSF
on the response from the gsmSCF.
10.2.1.2 Procedures gsmSSF..gsmSCF
Procedure at the invoking entity (gsmSSF or assisting gsmSSF)
Timeout occurs in gsmSSF on Tssf.
Precondition: gsmSSF FSM state "Waiting_for_Instructions"; or
gsmSSF FSM state "Waiting_for_end_of_User_Interaction"; or
gsmSSF FSM state "Waiting_for_end_of_Temporary_Connection".
Postcondition: gsmSSF FSM state "Idle".
The gsmSSF shall abort the TC dialogue and shall transit to the
state "Idle". The GMSC or VMSC shall handle the call
in accordance with the Default Call Handling parameter, valid for this
CAMEL dialogue. For CAMEL dialogues that
are established as a result of a CSI, the Default Call Handling parameter
is obtained from the CSI. For gsmSCF initiated
CAMEL dialogues, the Default Call Handling parameter shall be “ReleaseCall”.
The assisting gsmSSF shall abort the TC dialogue and shall transit to the
state "Idle". The assisting gsmSSF shall
release the temporary connection.
10.2.1.3 Procedures gprsSSF..gsmSCF
Procedure at the invoking entity (gprsSSF)
Timeout occurs in gprsSSF on Tssf.
Precondition: gprsSSF FSM state "Waiting_for_Instructions".
Postcondition: gprsSSF FSM state "Idle".
The gprsSSF shall abort the TC dialogue and and the GPRS dialogue and shall
transit to the state "Idle". The SGSN
shall handle the PDP Context in accordance with the Default GPRS Handling
parameter of the valid CSI.
10.2.1.4 Procedures smsSSF..gsmSCF
Procedure at the invoking entity (smsSSF)
Timeout occurs in smsSSF on Tssf.
Precondition: smsSSF FSM state "Waiting_for_Instructions".
Postcondition: smsSSF FSM state "Idle".
The smsSSF shall abort the TC dialogue and shall transit to the
state "Idle". The MSC or SGSN shall handle the Short
Message in accordance with the Default SMS Handling parameter of the valid
CSI.
