Abstract: A method and apparatus for assessing the compatibility of a selected network feature with the network features of an existing telecommunications network comprises providing an abstraction of each network feature in the form of a data model which defines the relationships between any network elements or nodes, software elements and software features required for each network feature. Information is then collected about the existing telecommunications network to identity the deployment of the network features in the existing network. This information is then combined with the data model to build a feature compatibility matrix which defines the compatibility of network features in the existing telecommunications network. The matrix can then be interrogated with information defining the parameters of the selected feature to be added or upgraded to determine whether the selected feature is compatible with features of the existing network.
