29.3 Testing of non transparent data services (RLP tests)
|
SS sends NULL (C/R=0, P/F=0) frames when it has nothing else to send in ADM mode.
SS does not use DTX if not explicitly indicated in the test and sends supervisory RR (C/R=0, P/F=0) frames when it has nothing else to send in ABM mode. N(R) is equal to N(R) of the previous frame. For the first frame N(R)=0.
The information field of the Supervisory frames sent by the SS is fully coded with "1".
The tolerance on timers or delays is ±10%.
The SS will check FSI (Frame Start Identifier) alignment in all received RLP frames. The information field of the Supervisory frames sent by the MS is never verified.
The SABM-UA exchange for RLP link establishment is initiated by the MS.
Immediately upon RLP link connection, the MS may send an I+S frame containing updated status bits SA, SB and X and the SS must send it.

Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use default RLP parameters.
MO data call:
The MS is made to establish a MO non transparent data call, so that the initial conditions are that the MS is in call state U10 ("Call Active") after having sent a CONNECT ACKNOWLEDGE message.
MT data call:
The SS establishes a MT non transparent data call, so that the initial conditions are that the MS is in call state U10 ("Call Active") after having received a CONNECT ACKNOWLEDGE message from the SS.
Case a: No negotiation will be initiated by the MS.
Case b: The MS initiates negotiation of RLP default parameters.
NOTE: The MS is allowed to initiate the negotiation of the RLP default parameters, within allowed ranges, defined in 3GPP TS 04.22. The MS shall do this in the ADM, after having sent a CONNECT ACKNOWLEDGE message (MO-case) or after having received a CONNECT ACKNOWLEDGE message from the SS (MT-case). The SS shall accept and use the new RLP parameters till the end of the test.
Procedure
The MS shall send a SABM frame.
The SS responds with a correct UA frame (within T1).
The SS waits for 2*T1 after the UA to ensure the SABM frame is not repeated. This confirms that the UA has been received.
The MS shall be in ABM mode. After optional status bits exchange between the MS and the SS, this is verified by sending an I + S frame and waiting for the acknowledgement from the MS.
The MS is returned to the idle state by clearing the call.

Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use default RLP parameters.
The MS is made to establish a MO non transparent data call so that the initial conditions are that the MS is in call state U10 ("Call Active") after having sent a CONNECT ACKNOWLEDGE message.
Case a: No negotiation will be initiated by the MS.
Case b: The MS initiates negotiation of RLP default parameters.
NOTE: The MS is allowed to initiate the negotiation of the RLP default parameters, within allowed ranges, defined in 3GPP TS 04.22. The MS shall do this in the ADM, after having sent a CONNECT ACKNOWLEDGE message (MO-case) or after having received a CONNECT ACKNOWLEDGE message from the SS (MT-case). The SS shall accept and use the new RLP parameters till the end of the test.
Procedure
The MS shall send an SABM frame.
The SS ignores the SABM frame from the MS.
The MS shall wait for time-out of timer T1 and then send a new SABM frame.
The SS ignores the SABM frame sent by the MS. These 2 last steps are repeated N2 times.
The SS waits for 2 * T1 to ensure the SABM frame is not repeated.
The MS shall not enter in ABM mode. This is verified by sending an I+S frame. The MS shall ignore this frame.
The MS is returned to the idle state by clearing the call.
Expected sequence:
MS SS
1 SABM >
T1 time-out
SABM N2 times
............................................................................................................................... SABM >
Wait 2*T1
< I+S 8
The frames from the SS will be:

29.3.2.1 Default conditions
|
The initial conditions are that the MS is in call state U10 ("Call Active") and in RLP ABM mode.
During the synchronization of the traffic channel, the MS and the SS have transmitted I+S frames. Unless, other indication in the test, each test of this subclause will begin in the following conditions:
- the MS has previously sent I+S frames numbered N(S)=0,...,Nms‑1 mod(62) and has previously sent a frame containing N(R) = Nss mod (62);
- the SS has previously sent I+S frames numbered N(S)=0,...,Nss‑1 mod(62) and has previously sent a frame containing N(R) = Nms mod (62).
The first I+S frame that an MS will send in a test will be numbered N(S)= Nms and the first I+S frame that the SS will send will be numbered Nss.

Initial Conditions
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use RLP default parameters except the window size from MS to IWF (SS), called Kmi.
A non transparent data call will be established, so that the MS is in call state U10 ("Call Active").
Since some RLP parameters are different from the default parameters, a negotiation procedure will be initiated by the MS after the CONNECKT ACKNOWLEDGE message. The MS may negotiate the RLP default parameters within allowed ranges, defined in 3GPP TS 04.22, except the window size from MS to IWF (SS), called Kmi, which has to be a non default value.
The SS shall accept and use the new RLP parameters till the end of the test.
After the negotiation procedure the ABM will be entered. This test is performed twice with 2 different values of Kmi, randomly chosen.
Procedure
After optional status bits exchange between the MS and the SS, the MS is made to send continuously I+S frames (more than 2*64 frames). The MS shall send I+S frames with N(S) incremented by 1 mod(62) in each frame.
The SS acknowledges the I+S frames in RR frame in sequence.
The MS is returned to the idle state by clearing the call.
Expected sequence

After the negotiation procedure the ABM will be entered.
This test is performed twice with 2 different values of Kmi, randomly chosen.
Procedure
The MS is made to send continuously I+S frames with a delay inferior to T1 between each frame.
The SS does not acknowledge the first Kmi frames.
The MS stops sending I+S frames after having sent Kmi frames, due to the window size.
The SS waits for 0,5*T1 after the last frame of the sequence (N(S)=Nms+Kmi‑1) to acknowledge the first j frames, with j<Kmi.
The MS shall transmit j new I+S frames and stop sending I+S frames after having sent them, due to the window size.
The SS waits for 0,5*T1 after the last frame of the sequence (N(S)=Nms+Kmi‑1+j mod (62)) to acknowledge all frames transmitted by the MS.
The MS shall transmit all the following I+S frames.

Test procedure
After optional status bits exchange between the MS and the SS, the SS is made to send continuously I+S frames. The delay between two consecutive I+S frames shall be inferior to T1.
The MS is made to send no user data. It sends only supervisory frames.
The SS sends a I+S frame numbered NSS. The MS shall acknowledge this frame. Then the SS sends a I+S frame numbered NSS+2.
The MS shall ask for the retransmission of the missing frame numbered NSS+1. The MS may send a SREJ frame (see case a). If it cannot send SREJ, it shall send a REJ frame (see case b).
Case a: If the MS chooses to send a SREJ, it shall send a SREJ frame containing N(R)=NSS+1.
The SS does not retransmit the rejected frame.
The MS may repeat (see case a1) or not (see case a2) the reject SREJ frame.
Case a1: If the MS chooses to retransmit the SREJ, it shall send a SREJ frame containing N(R)=NSS+1, at the expiry of T1.
The SS sends a I+S frame numbered NSS+1 and the MS shall acknowledge this frame (N(R)=NSS+3).
The SS sends a I+S frame numbered NSS+4.
The MS shall ask for the retransmission of the missing frame numbered NSS+3. The MS shall send a SREJ frame containing N(R)=NSS+3.
At expiry of T1, the MS shall send a new SREJ frame containing N(R)=NSS+3. This step is repeated N2 times.
The SS checks for 2*T1 that the SREJ frame is not repeated by the MS.
Case a2: If the MS chooses not to repeat the SREJ frame, The SS checks for 2*T1 that the SREJ frame is not repeated by the MS.
Case b: If the MS chooses to send a REJ, it shall send a REJ frame containing N(R)=NSS+1.
The SS does not retransmit the rejected frame.
The MS shall not repeat the reject REJ frame.
The SS checks for 2*T1 that the SREJ frame is not repeated by the MS.
The MS is returned to the idle state by clearing of the call.
Maximum duration of test
1 minute.

Initial Conditions
The window size from IWF (SS) to MS is called KIM.
System Simulator:
The SS is configured to use default RLP parameters.
Mobile Station:
The MS is configured to use default RLP parameters.
A non transparent data call will be established, so that the MS is in call state U10 ("Call Active").
Case a: No negotiation will be initiated by the MS.
Case b: The MS initiates negotiation of RLP default parameters.
NOTE: The MS is allowed to initiate the negotiation of the RLP default parameters, within allowed ranges, defined in 3GPP TS 04.22. The MS shall do this in the ADM, after having sent a CONNECT ACKNOWLEDGE message (MO-case) or after having received a CONNECT ACKNOWLEDGE message from the SS (MT-case).
