2013-07-03hsl: Remove the support for the HSL bts from OpenBSCHolger Hans Peter Freyther1-4/+0
The support has been implemented for an old model, we were told that newer versions would be made incompatible with OpenBSC. Ther are various warnings in the code and coverity has found some new ones. Just remove the code as we don't know of anyone using this code.
2013-03-17Add VTY option to set GPRS network-control-order to enable MS measurementsAndreas Eversberg1-0/+1
In order to enable GPRS downlink measurements at mobile, the network-control-order must be set to nc1.
2013-03-10si: Another round of PCS related fixesHolger Hans Peter Freyther1-2/+14
Inside the SI1 rest_octets we will need to indicate if the ARFCN is band 1800 or 1900. If the BTS is either 850 or 1900 we assume we are running a PCS network, otherwise it is a DCS network. The band indicator is not documented in GSM 04.08 but it is in the GSM 05.14 version 6.1.0 Release 1997.
2013-01-17si: Deal with DCS1800 and PCS1900 have overlapping ARFCN rangesHolger Hans Peter Freyther1-3/+23
For PCS1900 the SI1 does not contain the ARFCN of the serving cell. This is because the arfcn2band method will return GSM_BAND_1800 and not GSM_BAND_1900. The academic fix would be to set the ARFCN_PCS bit but this would require increasing the bitvector sizes from 1024/8 to (0x8000 + 1024) / 8. This would increase the storage size for each bitvector by three. It is not possible to have DCS1800 and PCS1900 in one network so we can avoid increasing the memory usage and check if the ARFCN resolved to 1800 and then check if the BTS is a 1900 BTS and then claim that this is compatible.
2013-01-17si: Share the ARFCN selection condition between the two statementsHolger Hans Peter Freyther1-30/+37
This makes reading the condition more easy and allows me to fix it for GSM1900 more easily and I can remove one level of indention.
2012-10-22si: Partially implement the range encoding for the SI.Holger Hans Peter Freyther1-25/+111
I saw the old copy of the "Appendix J" code too late and I have discovered some quirks and I am more familar with my implementation. Most noticable 'w' only needs to be as big as the input arfcn but requires the 'w' to be initialized. The power_of_2 implementation differs as well (mine matches the output of wirehsark). The f0 could be chosen in a better way but right now picking the lower bound is the easiest. It is not clear if to use modulo if the range is chosen in the middle. This can be improved in the future. Right now I have no bit fiddling for range128, 256 and 1024 as I was running out of time.
2012-10-08SI13: Set alpha value to a safer default of 0 instead of 10Harald Welte1-1/+1
alpha=0 (the new value) doesn't reduce MS transmission power during GPRS as much as we did with alpha=10. This is to optimize for coverage and to keep GPRS working at all cost, and not care about MS battery life time or uplink interference in surrounding cells. FIXME: This should be made configurable via the VTY and the normal default (unless configured otherwise by vty/config file) should be '6'.
2012-09-29Fix: T3192 and T3193 must be similarAndreas Eversberg1-1/+1
In order to keep mobile at PACCH as long as possible the timer T3192 is set to 1500ms. This reduces the probablity of long lasting assignment process on CCCH for subsequent downlink TBFs.
2012-07-02BSC: introduce new "sysmobts" BTS modelHarald Welte1-0/+4
so far, osmo-bts/sysmobts used to be entered as "sysmobts" type in the configuration file. However, there are some differences in the protocol/behaviour and we should reflect that by a new BTS plugin (with lots of code reuse from the nanobts driver).
2012-03-01Improved generation of SYSTEM INFORMATIONs 2* and 5* for neighbour bandsAndreas Eversberg1-21/+222
In addition to SI 2 and SI 5, the SI 2ter and 2bis is generated, if neighbour cells in other bands exist. Also it is indicated in the rest octets of SI3, that SI 2ter is used. If no neighbour cell in a different band exists, the SI 2ter and SI 5ter is omitted. A special case is P-GSM range (channels 1-124). To be compatible with older phones, SI 2bis and SI 5bis is used. If the BCCH lays inside the P-GSM band, only neighbour cells of the P-GSM range are included in SI 2 and SI 5. If neighbour cells exist in the same band (900), but lay outside the P-GSM range, the SI 2bis and SI 5bis is used to extend the list of neighbour cells. The extension is also indicated in SI 2 and SI 5. If the BCCH lays inside the P-GSM range, but no neighbour cell exists in the same band outside the P-GSM range, the SI 2bis ans SI 5bis are omitted.

2011-04-18misc: Remove sys/types.h includes from the filesHolger Hans Peter Freyther1-1/+0
These are not needed any more. We used them for u_int types but we now use uint which comes from stdint.h

This was done with sed on the files.

The HSL Femtocell seems to be a poor man implementation of the ip.access Abis/IP protocol, but cutting corners wherever possible. We try to workaround those corners wherever possible...
