Re: [Seagull-users] Reading input values of Grouped AVPs in Diametermessages

[Anjlica M. XX \(TX/EUS\) <anj...@er...>]

Just wanted to add some notes on how I got the grouped AVPs to work:

My grouped AVPs:
 Subscription-Id
	Subscription-Id-Type=20
	Subscription-Id-Data =20
     =20

Dictionary:
    <define name=3D"Subscription-Id" type=3D"Grouped">
      <setfield name=3D"avp-code" value=3D"123"></setfield>
      <setfield name=3D"flags" value=3D"123"></setfield>
      <setfield name=3D"Vendor-ID" value=3D"123"></setfield>
    </define>
    <define name=3D"Subscription-Id-Type" type=3D"Unsigned32">
      <setfield name=3D"avp-code" value=3D"456"></setfield>
      <setfield name=3D"flags" value=3D"456"></setfield>
      <setfield name=3D"Vendor-ID" value=3D"456"></setfield>
    </define>
    <define name=3D"Subscription-Id-Data" type=3D"OctetString">
      <setfield name=3D"avp-code" value=3D"789"></setfield>
      <setfield name=3D"flags" value=3D"789"></setfield>
      <setfield name=3D"Vendor-ID" value=3D"789"></setfield>
    </define>=20

Scenario:
<action>
.......
<restore-from-external field=3D"0" entity=3D"Subscription-Id-Data" =
begin=3D"0"
end=3D"12"></restore-from-external>
</action>
<command name=3D"ACR">
............
     <avp name=3D"Subscription-Id">
        <avp name=3D"Subscription-Id-Type" value=3D"0"> </avp>
        <avp name=3D"Subscription-Id-Data" value=3D"value_is_replaced">
</avp>    <------- MSISDN=3D19725830000
      </avp>
.............
</command>

External input file:
"string";
"0x3139373235383330303030" ;

Note: Only the data part of the AVP has to be substituted, not the
header.
"0x" has to be prepended infront.

Config file:
  <define entity=3D"traffic-param" name=3D"external-data-file"
value=3D"/home/username/seagull.svn/exe-env/diameter-env/config/external_=
d
ata.csv"></define>
  <define entity=3D"traffic-param" name=3D"external-data-select"
value=3D"sequential"></define>

Now the question remains that when I run 5 simultaneous calls, all five
fo them read the same input line from the file.
I would like each simultaneous call to pick each line sequentially from
the input file.

Well, I got that to work for setting the value of an AVP with in
command, eg the following sends the same grouped AVP value as I had in
my earlier example:

      <!--                                |code450|f|len12|val=3D0 =20
|code444|f|len20|val=3D640000001000         -->
      <avp name=3D"Subscription-Id"=20
value=3D"0x000001c24000000c00000000000001bc400000143634303030303030313030=
3
0">
</avp>


But unfortunately it doesn't work in a <set-value> action (because it is

treated as a string -- is there a way to override that?)

      <set-value name=3D"Subscription-Id"=20
format=3D"0x000001c24000000c00000000000001bc400000123634303030303030$(sub=
s
criber-msisdn)"></set-value>
