  1. 1. 2009 | Westergasfabriek | Amsterdam | http://eComm.ec
  2. 2. Is LTE being held hostage by voice telephony? eComm Europe 2009, October2009 dean.bubley@disruptive-analysis.com
  3. 3. About Disruptive Analysis  Analyst house & consulting firm  Founded by Dean Bubley  Blog at disruptivewireless.blogspot.com  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  If user behaviour changes, the handset’s behaviour & design should change too  Published “VoIPo3G” report Nov 2007 Oct 2009 Copyright Disruptive Analysis Ltd 2009
  4. 4. LTE – the latest, greatest mobile standard! Oct 2009 Copyright Disruptive Analysis Ltd 2009
  5. 5. Options for LTE voice 3GPP  IMS Voice, aka MMTel (Multimedia Telephony) standardised  Circuit Switched Fallback solutions  VoLGA  NSN Fast Track Voice  Mavenir / Acme Packet  Third-party VoIP on LTE data …. or stick with HSPA Oct 2009 Copyright Disruptive Analysis Ltd 2009
  6. 6. IMS… dead, but nailed to the perch of LTE 3GPP LTE Mobile IMS Oct 2009 Copyright Disruptive Analysis Ltd 2009 Fjords, aka RCS
  7. 7. 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 Oct 2009 Copyright Disruptive Analysis Ltd 2009
  8. 8. 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 Oct 2009 Copyright Disruptive Analysis Ltd 2009
  9. 9. 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? Oct 2009 Copyright Disruptive Analysis Ltd 2009
