Verizon Blames LTE 4G Network Problems on 'Growing Pains'

Verizon Wireless's VP of network engineering, Mike Haberman, blamed the three Long Term Evolution 4G network outages experienced this month on bugs in its IP Multimedia Subsystem (IMS) core. Speaking to GigaOM, Haberman explained that the Dec. 7 outage was caused by a failure of its back-up communications database; the Dec. 21 failure was caused by an unresponsive IMS element; and the Dec. 28 failure was caused when two IMS elements failed to communicate properly. Once resolved, none of the bugs resurfaced, but they were severe enough to prevent customers from accessing the 4G network -- and in some instances the 3G network -- despite the fact that both networks were actually up and running. "Being the pioneers, we're going to experience some growing pains," Haberman said. "These issues we've been experiencing are certainly regrettable but they were unforeseeable." Haberman said that Verizon Wireless has begun segmenting its LTE 4G network into regions around the country that in the future bugs might take out small areas of the network rather than the entire thing. "Our goal is to ensure that our 4G networks meets the same high standard that our 3G network does," Haberman said to GigaOm. "We're not there yet, but we'll get there."
