MS -> SS

EGPRS PACKET CHANNEL REQUEST

Received on RACH.

2

SS -> MS

IMMEDIATE ASSIGNMENT

Multi block assignment allocating two blocks using Multiblock Allocation Struct, to order the MS to follow the two-phase access procedure. Sent on AGCH.

3

MS -> SS

PACKET RESOURCE REQUEST

Two phase access procedure. Received on the multi block assigned in step 2. EGPRS capability indicated in the MS Radio Access Capability IE.

Check that the PEAK_THROUGHPUT, RADIO_PRIORITY and RLC_MODE are compliant with the PDP context used.

3a (conditional)

MS -> SS

ADDITIONAL MS RADIO ACCESS CAPABILITIES

If <ADDITIONAL MS RAC INFORMATION AVAILABLE> field in the received PACKET RESOURCE REQUEST message (step 3) indicates 1, then step 3a is performed.

3b (optional)

MS -> SS

uplink control block (e.g. PACKET MEASUREMENT REPORT, PACKET UPLINK DUMMY CONTROL BLOCK)

If <ADDITIONAL MS RAC INFORMATION AVAILABLE> field in the received PACKET RESOURCE REQUEST message (step 3) indicates 0, then step 3b is optionally performed.
