Covering Mobile VoIP since 2001
Regular focus on the links between innovative mobile network technologies & the impact on devices and applications New network technologies always have some implications for the
handset beyond the radio

LTE – the latest, greatest mobile standard!

Options for LTE voice
IMS Voice, aka MMTel (Multimedia Telephony)
Circuit Switched Fallback
VoLGA
NSN Fast Track Voice
Mavenir / Acme Packet
Third-party VoIP on LTE data
…. or stick with HSPA

IMS… dead, but nailed to the perch of LTE

LTE
Mobile IMS
3GPP
Fjords, aka RCS

Circuit switched fallback (CSFB)
So bad, it’s almost as if it’s designed to make IMS look good
Needs 2G / 3G coverage in same place
Extra seconds for call set-up (great for emergency calls)
Drops the data connection
Not great for multi-tasking
Not great for voice+data mashup applications
Not great for background apps
Nightmare for femtocells
Extra capex on the network side

SMS on LTE
Almost completely forgotten until it was too late
Original expectation was the early LTE devices would be data only –
laptops, dongles, MIDs
Only handsets need SMS, right? It can wait…..
Radio standards guys failed to realise that SMS is used for:
Roaming lists
Advice of charge
Device management
…. and 10-20 other IT systems for mobile broadband.
Panicked rush to do a workaround called SMS-over-SGs
Tied into CSFB but doesn’t force LTE-> 2G / 3G
Might even work… eventually

Recipe for disaster
Totally new radio network
Shift of #1 and #2 source of $$ from CS to VoIP
No workable standard
No handsets
No clear specifications
Multiple options = interoperability & roaming nightmare
Forgot about SMS entirely
Still batting around options at end-2009
LTE in 2010? ….. Or maybe 2014 is more likely?
… or just stick with HSPA+ in 2.6GHz, 900MHz etc?
