Routing of traffic

To prevent tromboning, traffic routed incorrectly will be cut off by the interconnect switch of the individual network operator.

The Danish numbering plan are controlled by the Regulator and is fully implemented in the solution for routing and charging purposes.
The plan supports every kind of number:

  • Fixed
  • Mobile
  • Prepaid / postpaid

The plan is divided into two main areas, the Range part and the Portability part. The plan contains the full history of all portings, including series and ranges that has taken place in the past, as well as the option of intensive monitoring of all ongoing porting flows.

The plan provides an easy and manageable way to receive the current status of any given phone number, i.e. Information about the Service Provider, Network Operator, Routing information and Charging information.
