All-IP networks is the in thing in wireless infrastructure networks. If you look for more information in the web, most of the documents talk only about what All-IP networks is all about.
What they don’t tell is, what was the world like before it was all IP.
I hit upon this article after a lot of search.
Some excerpts here.
“An IP wireless network would replace the old SS7 (Signaling System 7) telecommunications protocol, a task that many believe to be long overdue. “The SS7 network is massively redundent,” says Kempf. That’s because SS7 signal transmission uses a heartbeat that consumes a large part of the network bandwidth even when there is no signaling traffic. IP networks use other less bandwidth-expensive mechanisms to achieve reliability”
“IP tolerates a variety of radio protocols. It lets you design a core network that gives you complete flexibility as to what the access network is,” observes Kempf. “You could be a core network provider that supports many different access technologies, 802.11, WCDMA, Bluetooth, HyperLAN, and some that we haven’t even invented yet, such as some new CDMA protocols.” An all IP network’s technology tolerance means unimpeded innovation all around. “The core [IP] network can evolve independently from the access network. That’s the key for using all IP,” says Kempf.
With IP, you basically get rid of the lock-in between the core networking protocol and the link layer, the radio protocol
