Hi Jim : Actually , my previous experience is working inside an operator in HK which having the HSPA network , with 10 years IP core networking experience In more technical , there shouldn't be the IMEI number , IMEI number is your mobile ident. number . I think you're talking about the IMSI . HLR (Home Location Register) will lookup your IMSI , in order to verify which MSISDN (Mobile Number) are using and which kind of APN you're able to use , and of course , QoS control profile inside mobile element from BSC > MSC > SGSN > GGSN FYI : Sample HLR information HLR have a field which used to define which APN using which speed gei... PACKETDATAPROTOCOLCONTEXTDATA APNID PDPADD EQOSID VPAA PDPCH PDPTY PDPIDAPNID PDPADD EQOSID VPAA PDPCH PDPTY PDPID 0 365 NO IPV4 10 365 NO IPV4 1 1 365 NO IPV4 21 365 NO IPV4 2 FYI : http://www.lnic.net/ydtx_9.htm On the other hand , I found 3 HK's outgoing connection limit has been reached , it's mostly the problem on Gi Firewall (a firewall in front of the GGSN in order to protect over billing) , which doesn't have enough PAT / NAT , and session limitation on it Beside the Gi Firewall and QoS profile , there's the limitation on the radio , R4 of 3GPP element may not able to support more then 2 upstream are running 384K upload , it's most likely support "1" upstream which driving 384K upload as well , hence we're just like using the GPRS . Radio planning is also a problem , we didn't know their radio planning is 64K planning or 384K planning as well. |
