Wouldn't it make more sense in the phy_link? Also, if it must be introduced here, then it should be a sub-structure like struct { .... } lc15; https://gerrit.osmocom.org/#/c/239/1/src/osmo-bts-litecell15/lc15bts.h File src/osmo-bts-litecell15/lc15bts.h: PS1, Line 81: SM_BTS_M as far as i can see, all these constants are LC15 specific, so they should probably not have the generic GSM_BTS_ prefix, but something that indicates they are LC15. https://gerrit.osmocom.org/#/c/239/1/src/osmo-bts-litecell15/lc15bts_vty.c File src/osmo-bts-litecell15/lc15bts_vty.c: Line 354: "max-cell-size <0-166>", you introduce a lot of configuration locally to the BTS. This is quite contrary to the classic GSM architecture approach where all configuration is down-loaded via A-bis OML from the BSC, and related configuration is at the BSC. I'm not fundamentally against doing it this way, but your approach using the bts-local configuration file basically makes the configuration management of larger BTS populations much more complicated, as the operator will have to build a configuration and cofnig version management system for config files on all BTSs, as opposed to just one central at the BSC. If you look at the OML of Nokia/Ericsson/Siemens, these kind of settings are all part of their respective OML dialects. -- To view, visit https://gerrit.osmocom.org/239 To unsubscribe, visit https://gerrit.osmocom.org/settings Gerrit-MessageType: comment Gerrit-Change-Id: I3622d5b6f22525b798b0c75bbc2bab3767aba923 Gerrit-PatchSet: 1 Gerrit-Project: osmo-bts Gerrit-Branch: master Gerrit-Owner: Minh-Quang Nguyen <minh-quang.nguyen at nutaq.com> Gerrit-Reviewer: Harald Welte <laforge at gnumonks.org> Gerrit-HasComments: Yes
