MS behavior with dysfunctional GPRS
by Max 27 May '16

27 May '16

Hi. Imagine following configuration: - GSM network advertises GPRS capabilities in System Information messages - It's not actually available (SGSN crashed, all the timeslots are occupied by TCH etc) What would be expected behavior for MS in this scenario? Shall it switch to alternative network in hope of getting promised GPRS? Shall it hang on the currently camped network providing voice/sms only? Which spec(s) cover that? What could be decision factors for the MS? SIM entries, some data in SI, some timeout somewhere, smth else? -- Max Suraev <msuraev(a)sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Directors: Holger Freyther, Harald Welte

Hi All, We are trying to cross compile and test latest osmo-pcu, osmo-bts, openbsc, osmo-sgsn , and ggsn. One issue we see with latest sysmobts-mgr (Commit ed494443cc1e9732b43ef99cccf187d17ac931ef) on Nuran 1.0 is as below. - PA is off - Signal is very low - No signal on slave. With sysmobts-mgr preloaded(older commit version) on board, the setup works fine. Please help us in resolving this issue seen in master branch of osmo-bts latest commit. Regards Prasad

PCU sends invalid block number to L1
by Minh-Quang Nguyen 02 May '16

02 May '16

Hi All, We have noticed that the PCU sends invalid block number to L1 in DSP leading to unexpected message warning in DSP "GsmL1_PhDataReq(1) : Unexpected burst (Invalid blockNumber) [2!=1, SAPI 21-21]]". After an investigation, we observe that the 'pcu_rx_rts_req' function in pcu_l1_if.cpp receives invalid block number from BTS. Looking at the BTS side, the calculation of L1SAP_FN2PTCCHBLOCK defined as '#define L1SAP_FN2PTCCHBLOCK(fn) ((fn / 52) & 7)' does not seem to be valid for expected PTCCH block numbers B0, B1,B2,B3 defined in Table 6 in TS 05.02 version 8.11.0. What do you think about re-define the calculation of the L1SAP_FN2PTCCHBLOCK?
