Overlay micro cell structure for universal mobile telephone system network
First Claim
1. A method for achieving wireless communications in a network having at least one macro cell for communicating both voice and data with a mobile communications device across a first wireless link and, at least one micro cell, with a smaller coverage area and higher capacity per user than the macro cell, for communicating data with the mobile communications device across a second wireless communication link, the method comprising the steps of:
- communicating signaling information between the one micro cell and the one macro cell via a third wireless channel in response access of the micro cell by the mobile communications device; and
controlling the operation of the micro cell responsive to the signaling information.

Abstract
A wireless telephony communications system includes at least one macro cell for communicating both voice and data with a mobile communications device across a first wireless link and at least one micro cell for communicating data with the mobile communications device across a second wireless communication link. Each micro cell communicates signaling information through the macro cell via a wireless link to a control element that manages the micro cells. Using a wireless link to communicate signaling between each micro cell and the control element in the UMTS system eliminates the need for a wired back haul link, thereby reducing access costs.
