The invention provides a method for allocating communication resources in a communication network that comprises a number of different devices and utilizes different technologies. Information is collected of the number of devices of the network. The collected information is transformed from their formats to a common format. The common format makes it possible to handle efficiently all information. Current resources of the communication network and current use of the resources are determined utilizing the collected information in the common format. Alternative ways to use the resources are investigated instead of the current use, and a suggestion(s) is made to use at least one alternative way in case it is more efficient than the current use.
