Reply To: Roaming between GSM and CDMA


Due to many reasons CDMA intl’ roaming is realised using IIFs (vHLR + vMSC + vSMSC.. Possibly)..

This has invoked, these IIF or clearing houses to incorporate GS< CDMA interworking using addtional modules on IIFs... MAP conversion for CDMA to GSM and GSM to CDMA is fairly simple concept on SS7..
