Bug #4338
Updated by pespin over 4 years ago
I create this ticket to document process of adding some sample test validating EGPRS against osmo-pcu. Probably the easiest would be to start and create a TC_mo_mt_ping_egprs(). <pre> When the mobile station has received the PACKET UPLINK ASSIGNMENT message it shall respond with a PACKET RESOURCE REQUEST message in the first allocated radio block. A mobile station supporting EGPRS shall indicate the EGPRS capability in the MS Radio Access Capability 2 IE of the PACKET RESOURCE REQUEST message. </pre> https://issuu.com/leliwa/docs/signalling_in_gprs_egprs_chapter_03/30 page 44-45/68. That's two-phase access to get EGPRS TBF: * MS sends RACH on CCCH asking for UL TBF * Network sends IMM ASS on AGCH/PCH providing PDCH + TLLI + TFI * MS sends PACKET RESOURCE REQUEST on PDCH assigned with "MS Radio Access Capability 2" IE stating it supports EGPRS * The network should send an PACKET UPLINK ASSIGNMENT with updated CS * MS answers with PACKET CONTROL ACK * MS can now send whatever data.
