What I think we have to do before HAR is as follows:
Actual code¶
absolutely required¶
- finish and test the SMS implementation [Harald]
- make sure we enable MS power control and impose a global limit of 100mW for the uplink (MS->BSC) direction by means of the MS POWER IE's and the BCCH information. That sounds like something for Dieter to figure out, especially since he has measurement equipment ;)
- test dual-BTS-on-single-E1-card config [Harald]
- up to now, we have only tested with two nanoBTS, not BS-11 !
- test dual-TRX operation of BS-11 on OpenBSC [Stefan/Daniel, can you do that?]
- channel allocator can be tweaked to give 2nd TRX a preference for debugging
optional¶
- implement a 'provisioning mode' to OpenBSC that
- acccepts every new IMSI the first time we see it
- sends a SMS with a auth token to that mobile
- disconnects that mobile immediately
- implement a web site / cgi script
- once user enters correct tuple of ISMI + auth code, we
- assign him a number (user cannot choose, we assign)
- set authorized=1 in the sql table
- once user enters correct tuple of ISMI + auth code, we
- implement a web site bug tracker for user bug reports
- the should include detailed information about the phone model, his phone number and the exact timestamp, so we can match it in the pcap's
- add more introspection code for the VTY interface to explore the run-time data structures in OpenBSC
- implement different TCH assignment schemes (early / very early / OCASU)
- do we really want a SDCCH/8 or is SDCCH/4 for each BTS sufficient?
- some more testing with two BTS
- in case we call a user who is currently offline/busy, generate SMS about missed call and store it in the SMS table
- web interface ideas
- SMS gateway where people can send SMS from the web site
- SMS spam function for us in case we want to inform users about something
- simplistic phone book
- SMS gateway where people can send SMS from the web site
- enhance vty interface with administrative functions such as
- ability to close arbitrary channels (i.e. terminate a call)
- ability to kick-ban a user out of the network
- set authorized=0
- perform authentication procedure with reject at its end
- make sure we store all the 'this phone was registerd before to MCC/MNC/LAC' from the LOC UPD REQ data
- make sure we really store the classmark1/2/3 together with IMEI in SQL table
Things to bring to the event¶
- spectrum analyzer [from CCCB]
- stable OCXO reference to calibrate BS-11 internal clock
- this could be done before the event, but Harald has no precision clock source
- trace mobiles / monitor mode mobiles (if anyone has some)
- some poles to which we can mount the BS-11 ?
Misc¶
- draft 'usage terms & conditions' to be put on the registration web site and the HAR2009 wiki, indicating
- all signalling and traffic data will be stored for R&D purpose
- we do not employ authentication and/or encryption
- we do not provide any service guarantee
- this is for evaluation+testing only
- no handover/roaming and/or external calls
- no warranty for any damage to MS, SIM, ...
- IMSI/IMEI information will not be disclosed by us, but people can sniff it
IMSI Statistics¶
