MMS

MMS XL to XL from Another country

Several hours ago I tested MMS XL to XL from operator on another country which has GPRS interconnection with XL.

I though that the MM will be send from their MMSC, but I was wrong. The MMS flow is same comparing to MMS XL to XL in Indonesia

Here’s the test that I did

A# use XL number, send MMS to him/his self and he/she roam in another country (use another operator network)
For this case A# same with the B#

MO

MS – GGSN A# – GGSN XL – WAPGW XL – MMSC XL

MT

MMSC XL – SMSC XL – GWMSC XL – GWMSC B# – MS

after the MS received WAP push notification, the B# get the MM

MS – GGSN B# – GGSN XL – WAPGW XL – MMSC XL

The important thing is, the WAPGW receipt Accounting Request from XL-GGSN, not the another operator GGSN. It’s look like P2P connection in internet.
