Abstract
A method, system and device for communication establishes communications sessions between otherwise incompatible communication networks. A central unit is used to facilitate communication systems between objects, by referring to a database of communication attributes associated with different communication networks used by a calling part and a called party. Rather than have direct connections from one communication network to a next communication network, and having unique translators to support such direct connections, each of the communications is directed to a central facility, that identifies common protocols that are supported by the different communication networks to be employed when establishing a communication session between a first communication network and a second communication network. Included at the central facility is a database having subscriber information, and a network number associated with a subscriber, where the network number has associated therewith different communication numbers assigned to that subscriber in the different communication networks at which the subscriber may be located.
