Need info on how to pass IMEISV

[rajkirandav]

Hello Experts

I would need your help .M trying to pass IMEISV from MTS but the encoding is not okay and hence the OCS at other sides is failing to decode the values .THis is what MTS says

User-Equipment-Info - RFC 4006: allows the credit-control client to indicate the identity and
capability of the UE
- User-Equipment-Info-Type: IMEISV|MAC|EUI64|MODIFIED_EUI64
- User-Equipment-Info-Value - OctetString: for IMEISV type the value shall be a UTF-8 encoded decimal :
IMEI (15 digits) + SV (2digits)

What i have tried (IMEI:490154203237518)

parameter name="[User-Equipment-Info-Type]" operation="set" value="0"

parameter name="[User-Equipment-Info-Value]" operation="set" value="490154203237518"

But it fails .Could you please share info on how should i encode & pass the values and put in on MTS scenario ?
