Testing internet traffic via sgsnemu -still needs some effort to announce a mobile subscriber or the like (I have -used a real BTS, osmo-sgsn and a testing SIM in a web phone, instead). - -The core capability of GTPHub is to manage more than two GSNs, e.g. an SGSN -contacting various GGSNs over the single GTPHub link. You would configure the -SGSN to use one fixed GGSN (sending to gtphub) and gtphub will resolve the -GGSNs once it has received the messages. So the SGSN may be behind NAT (add -"sgsn-use-sender" to gtphub.conf) and communicate to various GGSNs over a -single link to gtphub. - -I hope this helps to get you going. -Any suggestions/patches are welcome! - -~Neels - |
