2012-07-26Changes RLC/MAC code from C++ to Cjolly/outdated_cAndreas Eversberg1-20/+4
2012-07-26Moved all bitvector code to seperate fileAndreas Eversberg1-25/+4
This is required to remove C++ from other code.
2012-07-26Use final_ack_sent and contention_resolution_done to define ongoing UL TBFAndreas Eversberg1-1/+2
Both flags can be used to determine wether assignment must be sent on PCH or on AGCH. Before contention resolution is done, mobile will ignore downlink assinment. When final uplink acknowledge was sent, the mobile will go back to PCH after reception of akcnowledge.
2012-07-24Added debugging of downlink bandwidthAndreas Eversberg1-0/+3
2012-07-23Fix: gprs_rlcmac_trigger_downlink_assignment() selects correct channelAndreas Eversberg1-2/+2
In order to select correct channel (PCH or PACCH), a tbf pointer is set in case of PACCH. The tbf pointer points to TBF whose PACCH is used.
2012-07-23Fix: We don't use timer to define when assignment is complete on PACCHAndreas Eversberg1-2/+1
Instead we use the event of sending assignment message. Then we set the TBF state to 'FLOW'.
2012-07-23VTY: Select timeslot allocation algorithm via VTYAndreas Eversberg1-6/+10
The selections are: single slot or multislot
2012-07-21Add check of lifetime of LLC frameAndreas Eversberg1-0/+1
If lifetime expires of queued LLC frames, they are discarded. The number of discarded frames and the sum of their octets are reported to SGSN via LLC-DISCARDED message. The lifetime can be overridden via VTY. The value can be centi-seconds or "infinite".
2012-07-20VTY: Added option to force given CS and ignore the scheme given by BTSAndreas Eversberg1-1/+6
2012-07-19Added paging for RR connection on PACCH of active TBFsAndreas Eversberg1-0/+23
Untested
2012-07-15Fixed contention resolution issueAndreas Eversberg1-0/+1
In order to do downlink assignment during uplink TBF, the content resolution must be completed. It is completed when the first Packet Uplink Ack/Nack message is transmitted to the mobile.
2012-07-15multislot: Rework of handling control channel / pollingAndreas Eversberg1-7/+20
In order to send control blocks to MS and receive control blocks from MS (polling), it is required to select one timeslot that the MS must be able to send and receive. The allocation algorithm must take care of selecting that slot.
2012-07-13multislot: Extracted "slot allocation algorithm" from tbf allocatorAndreas Eversberg1-1/+5
The current available algorithm only supports selecting a single slot for downlink/uplink. (In the future, a multislot algorithm will follow.)
2012-07-13Changed data structures for TBF and PDCH instances, to allow multislotAndreas Eversberg1-22/+33
The new data structure is required to define slot/TFI assigment for MS with multislot capability. Now there are two lists for TBFs: uplink and downlink. It is possible to have different TBFs with same TFI in the same direction, as long as they are assigned on different timeslots. See tbf.txt for description. Note: This does not implement any multislot support. It defines the new data structure. Currently only the first slot is assigned.
2012-07-12Merge branch 'jolly_new'Ivan Kluchnikov1-68/+180
Merge is based on jolly_new branch with two modifications. 1. Modified PCU L1 interface. pcu_l1_if.cpp - common functions for tx and rx messages on L1 interface. sysmo_sock.cpp - SYSMO-PCU socket functions. openbts_sock.cpp - OpenBTS-PCU socket functions. pcuif_proto.h - L1 interface's primitives. 2. Modified encoding of RLC/MAC Control messages, now we use structures and encode_gsm_rlcmac_downlink() function for encode control blocks (without hand-coding).
2012-07-09Send downlink IMMEDIATE ASSIGNMENT on PCH and not on AGCHAndreas Eversberg1-1/+1
The IMSI is used to define paging group on which it is sent. This is tested with MS that requires correct paging group.
2012-07-06Cleanup of BSSGP code.Andreas Eversberg1-1/+1
The hack for resetting BSSGP instance is removed and now performed whenever the NS state changes to UNBLOCKED. The BSSGP instance is now created only once, as it should be. Received STATUS messages are ignored as they should be. The creation and destruction of BSSGP/NS instances is now handled by layer 1 interface alone.
2012-07-06RLC/MAC process makes use from attributes, received from PCU socketAndreas Eversberg1-8/+0
For OpenBTS interface and BSSGP, fixed values are still used.
2012-07-06Receive cell informations via PCU socket interfaceAndreas Eversberg1-2/+13
These informations provide RAI, timers, counters and other attributes to the BSSGP and RLC/MAC processes. The attributes are stored in gprs_rlcmac_bts global structure.
2012-07-03TBF acknowledged mode finished for both link directionsAndreas Eversberg1-29/+101
2012-06-29Implemented Paging procedure on CCCH.Ivan Kluchnikov1-0/+2
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.
2012-06-29Fixed DL TBF establishment on CCCH.Ivan Kluchnikov1-2/+1
We shouldn't use paging procedure for DL TBF establishment, if we didn't receive paging message from BSSGP.
2012-06-27Modified encoding of Packet Downlink Assignment and Packet Uplink Ack/Nack ↵Ivan Kluchnikov1-1/+1
messages. Removed hand-coding of RLC/MAC Control messages, now we use structures and encode_gsm_rlcmac_downlink() function for encode control blocks.
2012-06-27Work on RLCMAC layer. Integration of scheduler and new packet transferAndreas Eversberg1-11/+92
2012-06-26Merge branch 'jolly'Ivan Kluchnikov1-3/+10
Merged jolly branch with master, fixed conflicts.
2012-06-25Packet Downlink Assigment now uses ARFCN/TN of current BTS layoutAndreas Eversberg1-0/+2
Now the MS receives dowlink LLC frames.
2012-06-23Split of L1 interface to be used with OpenBTS or sysmo-BTSAndreas Eversberg1-5/+10
The OpenBTS socket functions are moved from main to pcu_l1_if.cpp. New sysmo_l1_if.cpp is introduced. It used special unix socket interface to connect to sysmo-BTS. This is required to access CCCH/RACH and info about cell layout. Traffic is also forwarded via this interface, but it direct access of L1 baseband DSP will be added soon. In order to handle ready-to-send requests above l1_if, the transmit queue (for downlink blocks) is moved to gprs_rlcmac.cpp. The TBF instance additionally holds TRX and TS info, but this is only a hack currently. TBF instance requires more details about allocated ressources in the future.
2012-06-17Improvement of TBF management.Ivan Kluchnikov1-18/+61
Added functions for TBF allocation, establishment, data transfer and release management. Modified TBF structure, added list for several LLC PDUs in one TBF. Added function gprs_rlcmac_tx_llc_pdus() providing transmission of several LLC PDUs in one TBF to MS.
