From 4382e4e8fe05b59492ab1b38ddb5972831d0b533 Mon Sep 17 00:00:00 2001 From: Max Date: Tue, 30 Jan 2018 12:00:08 +0100 Subject: Move paging generation into PDCH Previously paging was prepared inside BTS function and than handed over to PDCH function. Move the actual preparation into PDCH to better decouple PDCH from BTS.
