Method and system for operating a user equipment device in a private network

Method for operating a user equipment device in a private network by a visiting device from outside the private network, each device being connected via a server gateway to a network function on a common server outside the private network, comprising the steps of: (i) creating and managing a private network context for both the user equipment device and the visiting device by each respective network function; (ii) consulting one or more databases defined by the network functions to authenticate the user equipment device and visiting device and subsequently determine whether the user equipment device and visiting device are allowed to join their private contexts; and if they are allowed to join their private contexts, (iii) setting up connections between the network functions on the server to join the private contexts of the user equipment device and visiting device and therewith allow interaction between said devices.
