Parameter OpenBTS

  • CLI.Prompt – Prompt for the OpenBTS command line interface.
  • Control.GSMTAP.TargetIP – Target IP address for GSMTAP packets; the IP address of Wireshark, if you use it for GSM.
  • Control.LUR.AttachDetach – Attach/detach flag. Set to 1 to use attach/detach procedure, 0 otherwise. This will make initial LUR more prompt. It will also cause an un-regstration if the handset powers off and really heavy LUR loads in areas with spotty coverage.
  • Control.LUR.CachedAuthentication – If not NULL, use RAND-SRES pairs cached in the TMSI table for authentication. If this method is used, it is important that the TMSI Table be in persistent storage.
  • Control.LUR.DefaultAuthenticationAccept – If not NULL, provisioned handsets will be accepted for authentication in the absence of any defined authentication method. For commercial networks this value should probably be NULL.
  • Control.LUR.FailedRegistration.Message – If defined, send this text message, followed by the IMSI, to unprovisioned handsets that are denied registration.
  • Control.LUR.FailedRegistration.ShortCode – The return address for the failed registration message. If the message is defined, this must also be defined.
  • Control.LUR.NormalRegistration.Message – If defined, send this text message, followed by the IMSI, to provisioned handsets when they attach on Um.
  • Control.LUR.NormalRegistration.ShortCode – The return address for the normal registration message. If the message is defined, this must also be defined.
  • Control.LUR.OpenRegistration – A regular expression. If not NULL, allow unprovisioned handsets with matching IMSIs to attach in Um.
  • Control.LUR.OpenRegistration.Message – If defined, send this text message, followed by the IMSI, to unprovisioned handsets when they attach on Um due to open registration.
  • Control.LUR.OpenRegistration.ShortCode – The return address for the open registration message. If the message is defined, this must also be defined.
  • Control.LUR.QueryClassmark – If not NULL, query every MS for classmark during LUR.
  • Control.LUR.QueryIMEI – If not NULL, query every MS for IMSI during LUR.
  • Control.LUR.SR-HTTPAuthentication – If not NULL, use the HTTP interface of the subscriber registry server for authentication.
  • Control.LUR.SendTMSIs – If not NULL, send new TMSI assignments to handsets that are allowed to attach.
  • Control.LUR.UnprovisionedRejectCause – Reject cause for location updating failures for unprovisioned phones. Reject causes come from GSM 04.08 10.5.3.6. Reject cause 0x04, IMSI not in VLR, is usually the right one.
  • Control.NumSQLTries – Number of times to retry SQL queries before declaring a database access failure.
  • Control.Reporting.PhysStatusTable – File path for channel status reporting database. Static.
  • Control.Reporting.TMSITable – File path for TMSITable database. Static.

  • Control.VEA – If not NULL, user very early assignment for speech call establishment. See GSM 04.08 Section 7.3.2 for a detailed explanation of assignment types. If VEA is selection, GSM.CellSelection.NECI should be set to 1. See GSM 04.08 Sections 9.1.8 and 10.5.2.4 for an explanation of the NECI bit.
  • GSM.CCCH.AGCH.QMax – Maximum number of access grants to be queued for transmission on AGCH before declaring congrestion.
  • GSM.CCCH.CCCH-CONF – CCCH configuration type. See GSM 10.5.2.11 for encoding. Value of 1 means we are using a C-V beacon. Any other value selects a C-IV beacon.
  • GSM.CCCH.PCH.Reserve – Number of CCCH subchannels to reserve for paging.
  • GSM.CellSelection.CELL-RESELECT-HYSTERESIS – Cell Reselection Hysteresis. See GSM 04.08 10.5.2.4, Table 10.5.23 for encoding. Encoding is 2N dB, values of N are 0...7 for 0...14 dB.

  • GSM.CellSelection.NCCsPermitted – NCCs Permitted. An 8-bit mask of allowed NCCs. Unless you are coordinating with another carrier, this should probably just select your own NCC.
  • GSM.CellSelection.NECI – NECI, New Establishment Causes. This must be set to ”1” if you want to support very early assignment. See GSM 04.08 10.5.2.4, Table 10.5.23 and 04.08 9.1.8, Table 9.9.

  • GSM.Identity.BSIC.BCC – GSM basestation color code; lower 3 bits of the BSIC. BCC values in a multi-BTS network should be assigned so that BTS units with overlapping coverage do not share a BCC. This value will also select the training sequence used for all slots on this unit.
  • GSM.Identity.BSIC.NCC – GSM network color code; upper 3 bits of the BSIC. Assigned by your national regulator. Must be distinct from NCCs of other GSM operators in your area.

  • GSM.Identity.MNC – Mobile network code; Must be 3 dgits. Assigned by your national regulator.
