Only some part of L3 is inherited (and significantly extended). L2 is completely different, L1 and the radio modem couldn't be any more different. The L3 "changes" on the PS side are bigger than those on the CS side. UMTS is not one telphony system, but more like an arbitray number of tools in a toolbox able to create any possible telephony system from it. Try understanding the phyiscal channels, transport channels and transport channel bundles of L2. That alone is a nightmare of complexity. -- - Harald Welte http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

I have seen the patch presented by Harald Welte and I printed the value of ?tn? and found out that it is always 0 whatever the IMSI of the sim card is. Did I miss something or is the paging group part still not implemented in the mobile app. I really appreciate any help.

Is there a way to increase the sensitivity of the phone ?

So, it would be good to see more details. Please, prepare two measurements using cell_log application: one inside any building, and another one outside. Attach both outputs from the cell_log and from the osmocon. I have several phones, and some of them have different RX signal level. I think, it's due to individual calibration tables, which aren't used in OsmocomBB firmware. BTW: if your phone's case is open, make sure that antenna is connected to the phone's board. With best regards, Vadim Yanitskiy. -------------- next part -------------- An HTML attachment was scrubbed...
