Abstract
A method for exchange of information between a requesting communication unit and a responding communication unit through an intervening communication unit. The method comprises the steps of transmitting a request for a predetermined information element to the responding communication unit using a first format, intercepting the request for the predetermined information element, searching resources local to the intervening communication unit for the requested predetermined information element, and transmitting the requested predetermined information element to the requesting communication unit. If the requested predetermined information element is not located in local resources, the method includes the steps of translating the request for the predetermined information element into a second format and transmitting the translated request to the responding communication unit, receiving the translated request, transmitting a representation of the requested predetermined information element to the requesting communication unit, intercepting the transmitted representation of the requested predetermined information element, expanding the representation to provide the requested predetermined information element, and transmitting the requested predetermined information element to the requesting communication unit. Apparatus for exchange of information is also described.
