I am having the question to one specific scenario related to the PD access and i am seeking for help on what should be correct hehavior of the network and the MS(I can not find clear answer from 3GPP spec.):

The scenario is as follows:

1) MS upper layer has the UDP data (ping) to be sent to network.

2) MS started the packet channel request with one phase as access type.

3) The network sends back immediate assignment and assigned the TBF 19

4) The MS sends the packet resource request and with two phase access as the access step.

5) The MS did not wait for the uplink assignment and started use the TBF 19 to send all 4 blocks of the data to netwoek.

6) The network send ack back to the MS and confirmed that the network received the 4 blcoks of data.

7) The network send back the uplink assignment message with TBF 20 to the MS 80 frames later after the step 7.


Question 1:

Can MS start the data transmission with phase 1 TBF assignment to network after it started the phase 2 access procedure but before it completed the phase 2 access procedure ??

Question 2:

What will the BSS do with the data received in phase 1 access in the above procedure? Will it forward to SGSN/GGSN/APN as if there is no phase 2 access request received or will it discard the data packets and cintinue to wait the MS to send out the uplink data packets ?
