Gy Diameter irule example
- Oct 12, 2022
try something like below.
replace parent with subscription-id
replace avp1 with subscription-id-type, avp1 value would be either 0 or 1 (set to match what you are looking for)
replace avp2 with subscription-id-data
vendor-id is optional, you can remove them or set to 0
# <parentAvpName>
set count [DIAMETER::avp count <parentAvpCode> vendor-id <parentAvpVendorId>]
set index 0
set myavp ""
while { $index < $count } {
set parent [DIAMETER::avp data get <parentAvpCode> grouped vendor-id <parentAvpVendorId> index $index]
# <avp1Name>
set child [DIAMETER::avp data get <avp1Code> <avp1Format> vendor-id <avp1VendorId> source $parent]
if { $child == "<avp1ValueId>" } {
# <avp0Name>
set myavp [DIAMETER::avp data get <avp0Code> <avp0Format> vendor-id <avp0VendorId> source $parent]
break
}
incr index
}note that you can generate this from diameter wizard (or diameter iAppsLX)
Hi JRahm,
Thanks for your kindly feedback.
Finally i can get those data from PS-info avp by getting the child avp from the grouped first then refer its as the new stream by source command. Thanks alot for your hint!..
i have another question for the Subsriber-ID (443) where this avp grouped is presented 2 times for the DATA-TYPE = IMSI(1) and E164(0) when i read the grouped is same 443 i always get only E164 but i expected the data with the IMSI type (1) then i want the avp 444 string in this grouped. If anyone can hint or suggest will be very very appreciated.
Best regards,
Taut S
when DIAMETER_INGRESS {
if { [DIAMETER::command] == 272 } {
log local0. "Codes all I: [DIAMETER::avp codes]"
set psinfo [DIAMETER::avp data get 873 grouped]
set ps874 [DIAMETER::avp data get 874 grouped source $psinfo ]
set charging_char [DIAMETER::avp data get 13 string source $ps874 ]
set 3gppimsi [DIAMETER::avp data get 1 string source $ps874 ]
log local0. "Session ID: [DIAMETER::session]"
log local0. "Found PSinfo codes count([DIAMETER::avp count source $app_spec_avp]) AVPs within PS-Info AVP"
log local0. "Codes under PSinfo 873: [DIAMETER::avp codes source $app_spec_avp ]"
log local0. "User: [DIAMETER::avp data get 1 string]"
log local0. "CC: $charging_char , IMSI: $3gppimsi"
}
}
glad the nudge was helpful. I think we need better documentation on the DIAMETER::avp page and maybe an article or two to help clarify how to use it. I'll ask around.
I probably won't be helpful with your follow-up inquiry, but hopefully we'll get some general answers. I'll let you know.
