State of Frequency Hopping in OpenBSC

Hi! I've now merged the 'laforge/hopping' branch to master, and wanted to update you on the state of frequency hopping support: First, the bad news: It is still not working with the BS-11 :( All OML attributes that I can think of are set correctly, they have been verified from wireshark, and the BTS acknowledges all those attributes. On RSL, the channels are activated the right way, and even the SYSTEM INFORMATIO 1 (cell channel allocation) as well as the chennel description and mobile allocation parts of the IMMEDIATE ASSIGN are encoded correctly. Still, the MS and BTS fail to establish any hopping channel. Dieter is now trying to get the BS-11 hopping configuration working with his Racal 6113. If that works, the protocol trace should reveal where we still do something wrong. If you want to play with it: The BTS attributes as well as the TRX attributes are not yet 100% finished like they should be. So you need to apply the attached patch as a hack on top of master. Please note that the bs11_attr_radio_trx1 contains hard-coded ARFCN 117 and 119, i.e. you will have to modify this unless your hopping sequence also only consists of those two ARFCN. I've also attached a config file for your reference. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
