Hi,

In detail how can i match the paging for my specific imsi/tmsi to the data-channel assignment?

You can't ... There is no relation between paging and the channel assignment.

When the phone sees he's being paged, he will initiate the channel request procedure.

He sends a RACH at a given time fn with a random reference (8bits). And then he looks for assignement matching his RACH (i.e. the time fn and random reference are repeated back by the network in the assignment so that a phone knows the channel was for it).

Cheers,

Sylvain
