An apparatus for resource sharing between a plurality of communication networks () each having a nominal resource allocation of a shared air interface resource and a resource exchange allowance is provided. The apparatus () comprises a sharing instigation processor () which initiates a temporary resource allocation of a first air interface resource from a nominal resource allocation of a first network (). A network interface () receives offer messages from a plurality of networks (). Each offer message comprises a resource exchange offer value for at least part of the first air interface resource. A selection processor () selects a second network () for example by selecting the highest offer value for a given resource. An allocation message generator () transmits a resource allocation message to the second network () indicating a temporary allocation of at least part of the first air interface resource. The resource exchange allowance of the second network () is then reduced by a value corresponding to the resource exchange offer value from the second network ().
