83.1.2.1.1 Conformance requirements
If the GANC receives a GA-PSR-ACTIVATE-UTC-REQ message from the MS while the network initiated GA-PSR TC activation procedure is in progress, the GANC aborts the network initiated activation procedure and responds to the MS with the GA-PSR-ACTIVATE-UTC-ACK message including the cause indicating successful activation. The message includes GANC IP address and GANC UDP port to be used for the uplink GPRS user data transport.
If the MS receives a GA-PSR-ACTIVATE-UTC-REQ message from the GANC while the MS initiated GA-PSR TC activation procedure is in progress, the MS shall silently discard the request and wait for the acknowledgment related to the MS initiated activation already in progress.
Upon receiving the uplink user data transfer request from the LLC for LLC SAPI 3, 5, 9 or 11 and while the MS GA-PSR is in the GA-PSR-STANDBY state, the MS shall,
– send a GA-PSR-ACTIVATE-UTC-REQ message,
– start timer TU4002,
– set the uplink packet sequence number to 0,
– set the expected downlink packet sequence number to 0 and

83.1.3.1 Processing of the GA-PSR TC Activation Request by the MS
83.1.3.1.1 Conformance requirements
Upon receiving the downlink user data transfer request associated with LLC SAPI 3, 5, 9 or 11 and if there is no GA-PSR TC associated with the specific MS, the GANC allocates the IP address and the UDP port number to be used by the MS for GPRS user data transport and sends a GA-PSR-ACTIVATE-UTC-REQ message to the MS. The GANC also:
– sets downlink packet sequence number to 0 and
– sets the expected uplink packet sequence number to 0
Upon receiving the GA-PSR-ACTIVATE-UTC-REQ message from the GANC, the MS shall verify the following:
– the GA-PSR is in GA-PSR-STANDBY state
– the GA-PSR TC does not exist
– the GPRS service is not suspended
Assuming successful verification, the MS shall allocate UDP port number for the MS GPRS user data transport and store the associated information. In parallel, the MS GA-PSR shall transition to GA-PSR-ACTIVE state and start TU4001 timer. Subsequently, the MS shall send the GA-PSR-ACTIVATE-UTC-ACK message to the GANC with the cause indicating successful activation. The message includes the MS UDP port to be used for the downlink GPRS user data transport.
After the MS has sent the GA-PSR-ACTIVATE-UTC-ACK message, it shall:
– set the uplink packet sequence number to 0 and
– set the expected downlink packet sequence number to 0
When the TU4001 timer expires and if there are no outstanding uplink GPRS user data messages to be transferred, the MS GA-PSR shall send the GA-PSR-DEACTIVATE-UTC-REQ message to the GANC to request the deactivation of the transport channel. In parallel, the MS shall start TU4002 timer to wait for the confirmation.

83.5.1.1 Initiation of the Downlink Flow Control and Processing of the TU4003 Timer Expiry by the MS
83.5.1.1.1 Conformance requirements
Upon detecting the downlink flow control condition, the MS shall initiate a downlink flow control procedure by sending a GA-PSR-DFC-REQ message to the GANC via the existing GA-PSR TC. The message includes new estimated data rate that can be supported. At the same time the MS shall start timer TU4003 to continue monitoring the flow control condition. The timer TU4003 is specified in sub-clause 12.
When the TU4003 timer expires, the MS shall re-evaluate the flow control condition and perform the following based on the outcome of the evaluation:
– If the flow control condition still exists (e.g. downlink buffer utilization is still above the low watermark level), the MS shall calculate a new data rate that can be supported and forward the corresponding GA-PSR-DFC-REQ to the GANC via the existing GA-PSR TC. Simultaneously, the MS shall start timer TU4003 to continue monitoring the downlink data transfer.
– If the flow condition has been resolved (e.g. buffer utilization is below the low mark level), the MS shall not restart the TU4003 timer and shall stop sending flow control requests to the GANC.
References
3GPP TS 44.318, subclauses 8.11.1 & 8.11.3

83.6 Uplink Flow Control
83.6.1 Processing of the Uplink Flow Control Request by the MS, Normal Case
83.6.1.1 Processing of the Uplink Flow Control Request by the MS
83.6.1.1.1 Conformance requirements
Upon detecting the uplink flow control condition, the GANC initiates an uplink flow control procedure by sending a GA-PSR-UFC-REQUEST message to the MS via the existing GA-PSR TC. The request is PFC based if the packet flow management procedures are supported.
Upon receiving the GA-PSR-UFC-REQUEST message from the GANC, the MS adjusts the uplink data rate accordingly.
References
3GPP TS 44.318, subclauses 8.12.1 & 8.12.2
83.6.1.1.2 Test purpose
To verify that the MS adjusts the uplink data rate accordingly with GA-PSR-UFC-REQUEST message received from the GANC.
83.6.1.1.3 Method of test
Initial Conditions
System Simulator:
– 1 GAN cell, default parameters
Mobile Station:
– MS GA-PSR is in the GA-PSR-STANDBY state. PDP context 1 is activated.
Forseen Final State of the MS
MS in Idle state
Test Procedure
The MS activates GA-PSR TC and starts to send lowest data rate to the SS. SS requests UL Flow Control sending the GA-PSR-UFC-REQ. The MS sends the data with rate adjusted according to GA-PSR-UFC-REQ.
The SS verifies whether the MS sends the data with adjusted data rate.

Initial Conditions
System Simulator:
– 1 GAN cell, default parameters
Mobile Station:
– MS GA-PSR is in the GA-PSR-STANDBY state. PDP context 1 is activated.
Foreseen Final State of the MS
MS in GA-PSR-STANDBY state in service of GAN cell
Test Procedure
The MS is in GA-PSR STANDBY state. MS is made to activate GA-PSR TC .SS sends the GA-PSR-UFC-REQ after the MS has initiated deactivation procedure. The MS ignores the flow control request and does not abort deactivation procedure. This is checked by verifying that when asked to send data after expiration of TU4002, the MS sends GA-PSR-ACTIVATE-UTC-REQ..
