A portable gateway apparatus communicates with devices coupled to a first network and devices coupled to at least a second network. The gateway provides an interface to a mobile phone to discover services/devices within both the first and the at least second networks and interacts with them. The mobile phone includes a service/content directory enabling a user to select preferred services. The gateway conducts service discovery to identify services and devices responsive to the user request. The services and description are provided to the user for selection, after which a service-specific interface is displayed to enable the mobile phone to control the execution of the discovered services.
