Any reasons why this can't be done without bits hand-coding?

commit c7e7f6868b6f24346424dee904f4e76d3f216ff4
Author: Ivan Kluchnikov <kluchnikovi(a)gmail.com>
Date: Fri Jun 29 22:53:15 2012 +0400
Implemented Paging procedure on CCCH.
Added functions:
- gprs_bssgp_pcu_rx_paging_ps() for handling paging message from BSSGP;
- write_paging_request() for writing paging request message;
- gprs_rlcmac_paging_request() and pcu_l1if_tx_pch() for sending paging
request message to BTS.

Fixed DL TBF establishment on CCCH.
We shouldn't use paging procedure for DL TBF establishment, if we
didn't receive paging message from BSSGP.
