Hi Ivan,

Any reasons why this can't be done without bits hand-coding? diff --git a/src/gprs_rlcmac.cpp b/src/gprs_rlcmac.cpp index 17120f9..711fb61 100644 --- a/src/gprs_rlcmac.cpphttp://cgit.osmocom.org/cgit/osmo-pcu/tree/src/gprs_rlcmac.cpp?id=bbbd79d6f1abd4e7f865f72c15878e0f32f252c3 +++ b/src/gprs_rlcmac.cpphttp://cgit.osmocom.org/cgit/osmo-pcu/tree/src/gprs_rlcmac.cpp?id=c7e7f6868b6f24346424dee904f4e76d3f216ff4 @@ -718,6 +718,35 @@ int write_immediate_assignment(bitvec * dest, uint8_t downlink, uint8_t ra, uint return wp/8; } +int write_paging_request(bitvec * dest, uint8_t *ptmsi, uint16_t ptmsi_len) +{ + unsigned wp = 0; + + bitvec_write_field(dest, wp,0x0,4); // Skip Indicator + bitvec_write_field(dest, wp,0x6,4); // Protocol Discriminator + bitvec_write_field(dest, wp,0x21,8); // Paging Request Message Type + + bitvec_write_field(dest, wp,0x0,4); // Page Mode + bitvec_write_field(dest, wp,0x0,4); // Channel Needed + + // Mobile Identity + bitvec_write_field(dest, wp,ptmsi_len+1,8); // Mobile Identity length + bitvec_write_field(dest, wp,0xf,4); // unused + bitvec_write_field(dest, wp,0x4,4); // PTMSI type + for (int i = 0; i < ptmsi_len; i++) + { + bitvec_write_field(dest, wp,ptmsi[i],8); // PTMSI + } + bitvec_write_field(dest, wp,0x0,1); // "L" NLN(PCH) = off + bitvec_write_field(dest, wp,0x0,1); // "L" Priority1 = off + bitvec_write_field(dest, wp,0x1,1); // "L" Priority2 = off + bitvec_write_field(dest, wp,0x0,1); // "L" Group Call information = off + bitvec_write_field(dest, wp,0x0,1); // "H" Packet Page Indication 1 = packet paging procedure + bitvec_write_field(dest, wp,0x1,1); // "H" Packet Page Indication 2 = packet paging procedure + bitvec_write_field(dest, wp,0x3,2); // spare padding + return wp/8; +} + void write_packet_uplink_ack(RlcMacDownlink_t * block, uint8_t tfi, uint32_t tlli, uint8_t fi, uint8_t bsn) { // Packet Uplink Ack/Nack TS 44.060 11.2.28

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.
