Abstract
There is stored a database of registration information associating UEs with cells under control of different network operators. In response to a inquiry from a first network operator that a first UE desires direct communications with a second UE, the registration information is used to coordinate between the first network operator and the second network operator to facilitate establishment of a direct communication link between the first UE and the second UE. In various embodiments the facilitating is enhancing the inquiry/page by adding a cell ID of the first UE's cell and adding pre-allocated radio resources in the first UE's cell for use by the second UE in responding to the page, and determining a single network which is not highly loaded and which can allocate resources for the D2D communications and directing one or both UEs to that single network.
