Abstract
The method provides for a first network controller, operating according to a first radio technology, to form and send a relay message to a second network controller, operating according to a different, second radio technology. The relay message includes an embedded message for the second network controller. The embedded message may be a transition message requesting transition of a packet switched call for a mobile station handled by the first network controller to a call for the mobile station handled by the second network controller. The method further provides selection of another wireless element for service at a wireless unit, using a current wireless element. A wireless unit receives a message identifying at least one other wireless element, available to the wireless unit and to which a wireless element currently in communication with the wireless unit is also in communication with and the wireless unit selects another wireless element for possible future service based on the message.
