Global Roaming, i.e., the combination of terminal and user mobility, requires the technology independent notion of a user who owns multiple devices. Any network infrastructure that supports global roaming needs to model and manage this user concept in a multi-technology subscriber database. This modeling not only requires the novel assignment of traditional subscriber attributes to the now separated entities of users, terminals, and addresses. For backward compatibility reasons, it also has to be compliant with the standard, single-technology subscriber models. Moreover, user configured inter-technology dependencies between service settings need to be taken into account to (1) enforce external integrity constraints, and (2) reduce space consumption of the multi-protocol subscriber base. The present invention a methodology for connecting to a subscriber having multiple devices accessible via a communications network and utilizing differing communications protocols. The methodology includes the steps of assigning at least one address to said subscriber; assigning at least one first type service profile per communication protocol used to set up a call request to said subscriber andassigning one second type service profile per each one of said devices. A destination selection policy is provided for describing routing parameters of an incoming call to the subscriber. A destination selection policy and the first and second type profile are referenced in order to make a connection to an appropriate one of said multiple devices using an appropriate one of said communications protocols. A user profile is disclosed which is a collection of at least one terminal profile and at least one incoming call handling (ICH) service profile, the ICH service profile includes the at least one first and second type profile.
