2019-02-19Clarify write_immediate_assignment() signatureMax1-5/+3
* remove unused variable * use bool for boolean types * add clarification comments Change-Id: I363445063e2d873d9194b2a5924b9e59b8b7ea53
2018-01-04window: move encoding into functionsMax1-1/+1
* move window size encoding and writing into separate functions * introduce necessary TBF wrappers to avoid direct m_window access This is part of preparation work to move to separate UL/DL windows. Related: OS#1759 Change-Id: I60184d5049bc7d7b119df5a9eb82d1c4b788c840
2016-11-11Handle packet access reject during EPDAN/PDAN with channel descriptionaravind sirsikar1-0/+3
When PDAN/EPDAN with channel description is received, PCU will generate the packet access reject if no resources are present. The encoding is done based on section 7.1.3.2.1 and 8.1.2.5 of 44.060 version 7.27.0 Release 7. This patch also includes the test case to validate the generated packet access reject message. This patch is integration tested on Osmo-trx setup with Ettus B210 board and LG F70 MS with some simulation code changes in Osmo-pcu. Change-Id: I096a3bb44a65533b9e9b091925dd5f70a8696d6

When RACH is received, PCU will generate the Immediate assignment reject message if no resources are present. The encoding is done based on section 9.1.20 of 44.018 version 11.7.0 Release 11. This patch also includes the test case to validate the generated Immediate assignment reject message. This patch is integration tested on Osmo-trx setup with Ettus B210 board and LG F70 MS with some simulation code changes in Osmo-pcu. Change-Id: I3d33e2b9746fa4f338fad0e6b63b1c5f07de6f9b
2016-09-16Update the function immediate assignment for EGPRSbhargava1-2/+8
Encode the EGPRS fields of immediate assignment message in uplink when EGPRS PACKET CHANNEL REQUEST (11 bit RACH) is received. The series of patches for 11 bit RACH are dependent on libosmocore and osmo-bts patches for 11 bit RACH. Change-Id: Ie5e309156e5dbbb6add74a1b4d257c4ee2332e52

2016-02-08encoding: Redesign Encoding::write_immediate_assignment APIJacob Erlbeck1-5/+5
The EGPRS support will need more information to encode the IMMEDIATE ASSIGMENT. Instead of adding more parameters pass a pointer to the TBF unless an SBA shall be done (indicated by tbf == NULL). All values that can be derived from the TBF and are not needed for an SBA are removed from the parameter list. Return a negative value on error. Sponsored-by: On-Waves ehf
2016-02-08tbf: Use TLLI as ID if TFI not yet assignedJacob Erlbeck1-1/+1
Currently the old TFI is always used as ID when a PACKET DOWNLINK ASSIGNMENT is generated. This fails if the old TBF has not been fully assigned yet. The MS will then ignore the PDA. This commit changes write_packet_downlink_assignment to accept an additional parameter old_tfi_is_valid and uses the new TBF's TLLI instead of the olf TFI if that parameter is set to false.

2016-02-08tbf: Add check_polling/set_pollingJacob Erlbeck1-7/+9
Currently the checks for and the actual polling is done in several places by copy & paste of several lines of code. This hinders changes of they polling is handled internally and also is likely source of programming mistakes. Separate this into a check_polling function, that checks whether polling is possible and returns the FN and the RRBP to be used in that case. Otherwise the cause is logged (LOGL_DEBUG) and a negative error value is returned. There are no other side effect beside the logging. If the call is successful, the set_polling method can be used to actually register the polling. Extend the encoder functions' parameters lists by an rrbp parameter. Sponsored-by: On-Waves ehf
2016-02-05edge: Select implementation by mode in rlc_data_to_dl_appendJacob Erlbeck1-1/+2
Currently the GPRS data block encoding is applied to every coding scheme, even if an MCS is selected. This commit renames the actual encoding function to rlc_data_to_dl_append_gprs (not exported) and puts selection code into Encoding::rlc_data_to_dl_append. This requires an additional cs argument.

2016-02-05edge: Add Encoding::rlc_data_to_dl_appendJacob Erlbeck1-0/+14
This function appends a single chunk to an RLC downlink data block. The implementation is basically taken from the gprs_rlcmac_dl_tbf::create_new_bsn method without the TBF related functionality and any side effects. Note that it still only supports GRPS. Sponsored-by: On-Waves ehf
2016-02-05edge: Add encoder for downlink RLC data blocksJacob Erlbeck1-0/+8
Currently the (GPRS) RLC block encoding is done by setting the header fields directly in gprs_rlcmac_dl_tbf::create_new_bsn. This is much more complex with EGPRS, since the data fields are not byte aligned, the header formats depend on the header type, and the mapping of bits to bytes is LSB first. This commit adds Encoding::rlc_write_dl_data_header which writes the header according to the given gprs_rlc_data_header structure. Encoding::rlc_copy_from_aligned_buffer is also added to copy byte sequences into the message. Note that the actual encoding of data units is not yet present. Sponsored-by: On-Waves ehf
2016-02-01edge: Support EGPRS in write_packet_downlink_assignmentJacob Erlbeck1-3/+5
Add an use_egprs parameter to write_packet_downlink_assignment and add the EGPRS related fields if it is set to true. The window size is fixed at 64 blocks, link quality measurement reports have been disabled, and the other optional fields are not present. Sponsored-by: On-Waves ehf
2016-02-01encoding: Remove RlcMacDownlink_t based write_packet_uplink_ackJacob Erlbeck1-2/+0
This is the CSN1-encoder based variant, which has been replaced and is no longer being used. Sponsored-by: On-Waves ehf
2016-02-01encoding: Add bitvec based write_packet_uplink_ackJacob Erlbeck1-0/+3
The current write_packet_uplink_ack implementation is based on the CSN.1 encoder which makes it difficult to do the bitmap encoding for EGPRS. Add a new implementation based on bitvec functions to create the PACKET UPLINK ACK/NACK messages. Sponsored-by: On-Waves ehf
2015-11-30edge: Support EGPRS in packet uplink assignment messageJacob Erlbeck1-1/+1
Currently the Encoding::write_packet_uplink_assignment method only supports the GPRS variant of the message. This commit adds the missing EGPRS variant to the encoder. Sponsored-by: On-Waves ehf
2014-08-07encoding: Change function signature to use UL TBFs where it makes senseDaniel Willmann1-2/+2
encode_rbb() and write_packet_uplink_assignment are only called with UL TBFs so change the function signature to reflect that. Ticket: SYS#389 Sponsored by: On-Waves ehf

2013-10-30encoding: Move the functions into the encoding classHolger Hans Peter Freyther1-0/+66
Add some TODO to this class. E.g. they could all work on the bitvec and the parameter handling could better.
