Abstract: The present invention provides a method involving at least one device belonging to a defined set in which a plurality of devices communicate with each other. The method includes encoding first information according to a first protocol for transmissions over at least one first air interface between at least two of the plurality of devices in the defined set. The method also includes forming second information for transmission according to a second protocol. The second information includes the first information. The method further includes transmitting the second information over a second air interface according to the second protocol.

Abstract: The present invention provides methods involving a first device, at least one second device, and a core network in a wireless communication system. One embodiment of the method includes establishing a first secure wireless connection over a first air interface between the first device and the at least one second device based on security information received from the core network using a second secure wireless connection over a second air interface.
