Misinterpretation of data from another international operator lead to about 1 million Telenor customers being without mobile coverage for several hours Friday, the company said.
Telenor has analyzed what they know as signaling to the mobile network in Norway. Among other things signaling include the information sent by the mobile phone in order to tell where it is, to connect calls or to check email.
– The analysis reveals that at the time of the crash irregular signaling was sent into the Telenor network. This irregular signaling was sent by another international operator and contained types of messages that appear very rarely, the company said in a statement.
– This signaling was misinterpreted in the software that Ericsson has delivered to Telenor’s mobile network and lead to part of the mobile traffic stopping, according to the company, which states that the error is corrected.
