Hi all, my current task is implementing inter-MSC Handover for OsmoMSC. It would be immensely helpful to look at network traces of the messages carrying out an inter-MSC handover. Primarily for 2G (BSSAP), but 3G (RANAP) might also be interesting. The part on the A-interface (BSSAP) is interesting for both the outgoing (orig. MSC and BSS) as well as the incoming (remote MSC and BSS) sides. Most interesting would be some kind of trace of communication between the two MSCs, the E-interface (MAP) negotiating the HO as well as the call forwarding between the two MSCs, if at all available. We are exploring various avenues to obtain inter-MSC HO traces, so far to no avail. If anyone reading this is able to help out, that would be highly appreciated and super helpful to be interoperable. Thanks! ~N -- - Neels Hofmeyr <nhofmeyr(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 * Geschäftsführer / Managing Directors: Harald Welte

35c3 feedback

Hi all. 1) SIP Connector handling of TON GSM340_TYPE_INTERNATIONAL Apparently at least one person was frustrated at the congress by not being able to call out using the numbers stored in their GSM handset using the form +CountryCode. As we know this appears at Call Control with TON intl, which sip connector then prefixes with '+' before sending to SIP The reason for lack of service at ccc was that the Yate pbx does not support this number scheme and needed the 00 prefix. This would have been trivial to patch had we known, and it prompts me to think this should probably be implemented as a runtime config option in sip section 'tonintl prefix' or some such? It would seem correct for it to be restricted to the set of either '00' or '+', no other options really makes sense, not even "no prefix". right? 2) 3G data instabilities ( Just a quick observation note, no pcap! ) I happened to notice that pinging a 3G handset from the network side (default ping: 1 sec internal, 64 ICMP bytes) keeps the connection "alive" and using 3G data is then a pleasant experience, IM, email, browsing, SIP call all working nicely. peak max download speed of 16Mbps was reported at one time by m.speedof.me However, stopping the ping results in loss of data conex within a few seconds, and the behaviour from users point of view is then strikingly similar to what's observed on 2G; and I am more or less convinced has to do with the unknown Timing Advance issues in the PCU. So I thought I'd note it down here. k/
