Network planning plays an important role in the overall responsibility to provide telecommunications and due consideration has to be given to a number of relevant factors, e.g. technical, economic and operational. International planning involves, by definition, a number of Administrations which may have different national objectives and may operate under different economic constraints. It is apparent, therefore, that these differences must be reconciled if cooperative planning is to be achieved. This Recommendation describes a possible method for concerned Administrations to organize a procedure to implement this cooperative network planning process.
