Reply To: AG_PREMPT_PCH parameter

Hello NarChai,

There is no information about the minimal number of PCH blocks in the frame, when using the AG_PREMPT_PCH = 1.

So I guess the AGCH can be assigned on all the CCCH blocks when needed, even though i doubt the case will ever happened !

(cf. PAGING AND ACCESS GRANT CONTROL B7 (or B9), p.50)

“Each PCH occurrence, the BTS will use this order to search the waiting queue for a pending message.
If there is a pending Access Grant message, and there is no PACKET DOWNLINK ASSIGNMENT in
the Paging Group’s associated queue, the BTS will preempt this PCH block to sent the Access Grant
message.”

Regards,
