osmoSGSN

Hi, I am trying to use osmoSGSN in topology with openGGSN and sim-bss, which is simulator of BSS made by company Alcatel-Lucent. I have a problem that my osmoSGSN can not communicate with sim-BSS and it can not connect correctly. It is caused by non function bssgp. I would like to ask you, how can I configure bssgp on osmoSGSN? I can configure ns states also from vty on osmoSGSN but I can not bssgp states such as bvci etc...Please could you help me? I hope you will reply me soon. Thank you very much Best regards, Michal Grznár
