A look at Multimedia Messaging (MMS) in 3GPP Networks and how it actually works.
Chances are if you’re reading this, you’re trying to work out what Telephony Binary-Coded Decimal encoding is. I got you. Again I found myself staring at encoding trying to guess how it worked, reading references that looped into other references, in this case I was encoding MSISDN AVPs in Diameter. How to Encode a number […]
As the number of Private Networks built on LTE and 5G grow, how will PLMN allocation be managed?
A look at tuning your SCTP parameters to detect failures quickly and reduce dropped packets when they happen.
5G introduces Network Slicing, or does it? A look at slicing mechanisms widely used in pre-5G networks.

Peculiar padding problem perplexes poor programmer.
How to find a subscriber location within the network.
Australia is a strange country; As a kid I was scared of dogs, and in response, our family got a dog. This year started off with adventures working with ASN.1 encoded data, and after a week of banging my head against the table, I was scared of ASN.1 encoding. But now I love dogs, and […]
A look at SCTP multi-homing in practice.
