Adding Custom AVPs

Simple AVP Tag Format

The following format must be used to define new custom AVP:

 < avp name="<avpName>"display="<displayText>" [vendor-id="<vendorId>"] code="<code>"type="<type>"/>

where

avpName must be unique AVP identifier in the dictionary file, if the vendorId is present then the name should be preceded by vendor-id (see the example below)
vendorId is optional and if present then must be either defined in the custom dictionary file, or must be one of the predefined ones
type must be one of the following predefined types:
- OctetString
- Integer32, Unsigned32, Integer64, Unsigned64
- UTFString
- IPAddress
- TBCD

Example:

< avp name="3GPP:3GPP-IMSI"display="3GPP-IMSI"code="1"vendor-id="3GPP"type="UTF8String"/>

Enumerated AVP Tag Format

The following XML tag format must be used to define new enumerated AVP

:< avp name="<avpName>"display="<displayText>" [vendor-id="<vendorId>"] code="<code>"type="type">
<enumcode="<value>"name="<enumDisplayText>">
. . .
</avp>

where

avpName , displayText, vendorId, code and type are the same as in case of simple AVP format
value is the numeric value and enumDisplayText is a text which is displayed in the full decoding window. If a named value is not defined, the decoder displays just simple numeric value

Example:

<avp name="Framed-Routing" display="Framed-Routing" code="10" type="Enumerated" >
        <enum code="0" name="None"/>
        <enum code="1" name="Broadcast"/>
        <enum code="2" name="Listen"/>
        <enum code="3" name="Broadcast-Listen"/>
    </avp>

Grouped AVP Tag Format

The following XML tag format must be used to define new custom grouped AVP:

< avp name="<avpName>"display="<displayText>" [vendor-id="<vendorId>"] code="<code>"type="type">
<avpref="<refAvpName>">
. . .
</avp>

where

avpName , displayText, vendorId, code and type are the same as in case of simple AVP format
refAVPName must be name of an existing AVP define in the custom dictionary

Example:

<avp name="3GPP:User-Identity" display="User-Identity" code="700" vendor-id="3GPP" type="Grouped">
        <avp ref="Public-Identity"/>
        <avp ref="3GPP:MSISDN"/>
        <avp ref="3GPP:Public-Identity"/>
    </avp>
