Status of GEA issues in OsmoSGSN
by Harald Welte 01 Jun '16

01 Jun '16

Dear all, Deater has been investigating which issues currently prevent us from using GEA in OsmoSGSN. His mail has been sitting in my inbox too long, and hence I'm forwarding his results here to the mailing list for further discussion / follow-up.

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

latest sysmobts-mgr failure on NURAN 1.0
by Prasad Kaup 25 May '16

25 May '16

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

Hi, as discussed at OsmoDevCon and the mails from last week. The following list of projects have moved to use gerrit for codereview: * libosmocore.git * libosmo-abis.git * libosmo-netif.git * libosmo-sccp.git * libsmpp34.git * openbsc.git * osmo-bts.git * osmo-iuh.git * osmo-pcu.git * cellmgr-ng.git * osmo-sip-connector.git I have created this[1] page with the minimum to set-up gerrit as git-remote, register, configure the account and then hopefully the most frequently used comments. kind regards holger [1] http://osmocom.org/projects/cellular-infrastructure/wiki/Gerrit

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?

[PATCH 0/4] Support for Incremental redundency in EGPRS DL
by Aravind Sirsikar 25 Apr '16

25 Apr '16

This series of patches supports Incremental redundency for EGPRS DL case. These patches have been integration tested on Nuran 1.0 for EGPRS MCS 9 support in DL. And in UL only MCS4 has been tested. The EGPRS testing has been done with Browsing and Ping in DL with larger packet sizes(1500).

by Aravind Sirsikar 18 Apr '16

18 Apr '16

Hi Harald, Can you please let us know the commit version for osmo-pcu which has been verified for EGPRS functionality on Nuran 1.0 hardware. We have been trying the latest commit 1aa75273025b033d17c1068369a7ba145d5c9f06 which does not work( no uplink data received yet). Can you provide details of the hardware in which EGPRS functionality has been successfully verified. Thanks, Aravind Sirsikar

[PATCH] Fix make distcheck
by msuraev＠sysmocom.de 13 Apr '16

13 Apr '16

From: Max <msuraev(a)sysmocom.de> Define automake variable for configure flags to be used while running 'make distcheck'. This should prevent additional vty tests from running in readonly distcheck environment.
