About six percent of all communications spending worldwide in 2009 will be for these converged services, the report says. That would account for about $80 billion in revenue, according to the report.
Driving the trend toward convergence is the already-started trend of users substituting land lines for mobile voice access, consolidation among major industry players and increasing interest in voice-over-IP, Svetlana Issaeva, the report's author said in a statement.
While those trends will have a strong impact on old-line telcos, wireless operators should focus now on launching 3G cellular data services if they are going to take advantage of the trend, the study concludes. That's because those operators are seeing less revenue from voice services.
"Mobile voice services are already commoditized and the migration to new IP-based convergent networks and platforms is only a matter of time," Issaeva said in a statement.
