2016-02-08	cs: Add GprsCodingScheme::optionalPaddingBits	Jacob Erlbeck	1	-0/+1
	Return the amount of optional padding bits, which is 6*8 for MCS-3 and MCS-6 and 0 for all other coding schemes. The padding is needed the encode 68 byte data blocks (MCS-8) with these schemes. See TS 44.060, 9.3.2.1 and Annex J for details. Sponsored-by: On-Waves ehf
2016-02-08	cs: Add family related methods	Jacob Erlbeck	1	-0/+11
	Add family handling and the related methods family, isFamilyCompatible, isCombinable, decToSingleBlock to GprsCodingScheme. Sponsored-by: On-Waves ehf
2016-02-05	edge: Add numDataHeaderBitsUL/DL and numDataBlockHeaderBits methods	Jacob Erlbeck	1	-0/+4
	These methods are added to GprsCodingScheme to avoid related switch statements in the RLC block encoder for EGPRS. Sponsored-by: On-Waves ehf
2016-02-05	edge: Fix RLC message size	Jacob Erlbeck	1	-0/+2
	Currently the RLC message length that is obtained from the DSP is reduced by 1 if the last byte of the buffer includes spare bits. While this worked well with GPRS, these bits are being used to encode RLC blocks in EGPRS mode. Thus this last byte must not be chopped off. The functionality of the code is not affected by this, since the modified length value is not used. This commit adds GprsCodingScheme::usedSizeDL/UL to return the number of bytes needed to encode the message block. If there are single bits at the end that are to be used (EGPRS), the functions return the number of full bytes plus 1 (which is the buffer size reported by the DSP and returned by sizeUL/sizeDL). The commit also removes the len parameter from rcv_data_block_acknowledged. Sponsored-by: On-Waves ehf
2016-02-05	edge: Remove int casting operator from GprsCodingScheme	Jacob Erlbeck	1	-4/+6
	This convenience operator rather hide implementation bugs and is thus removed. Sponsored-by: On-Waves ehf
2016-02-01	edge: Show current mode in VTY	Jacob Erlbeck	1	-0/+1
	Add the current mode to the output of the 'show ms imsi' and 'show ms tlli' commands. Sponsored-by: On-Waves ehf
2016-02-01	edge: Add methods and operators to GprsCodingScheme	Jacob Erlbeck	1	-29/+77
	Add a few new operators and methods to support the use of GprsCodingScheme instead of the plain integer currently used. Sponsored-by: On-Waves ehf
2015-12-15	edge: Add information about data blocks to GprsCodingScheme	Jacob Erlbeck	1	-0/+2
	This commit adds the methods maxDataBlockBytes and numDataBlocks which provide information about the data areas within RLC messages. In these areas, the extension bytes, TLLI, and the LLC data are stored. Sponsored-by: On-Waves ehf
2015-12-15	edge: Add header type property to GprsCodingScheme	Jacob Erlbeck	1	-0/+16
	The header type depends on the coding scheme, for GPRS there is a single data header type per direction, for EGPRS there are 3 per direction. In addition, control block header types are used with CS-1 only, so there is one of the per direction altogether for GRPS and EGPRS. This commit adds the header type enum and two methods headerTypeData and headerTypeControl. Sponsored-by: On-Waves ehf
2015-12-15	edge: Add GprsCodingScheme class	Jacob Erlbeck	1	-0/+129
	Currently the coding scheme is checked and compared at different places which makes in cumbersome to extend it for EGPRS. This class encapsules the coding scheme and provides required meta information like sizes as well as helper methods. Sponsored-by: On-Waves ehf
