Claim Text:
1. A method, comprising: assigning, by a system comprising a processor, service area code data to respective femto access point devices, wherein the service area code data represents service area codes comprising numeric indexes that characterize pilot code sequences of the respective femto access point devices; based on the service area code data, configuring, by the system, access data associated with the respective femto access point devices, wherein the access data is indicative of an authorization for a mobile device to access the respective femto access point devices; receiving, by the system, macro-to-femto transfer data from the mobile device; in response to verifying that the macro-to-femto transfer data comprises a request to transfer a first coupling between the mobile device and a macro access point device to a second coupling between the mobile device and a femto access point device that is not part of the respective femto access point devices, determining, by the system, whether the mobile device is authorized to access the femto access point device; and in response to determining, based on the access data and a Zadoff-Chu sequence of the pilot code sequences, that the mobile device is not authorized to access the femto access point device, prohibiting, by the system, the mobile device from measuring a pilot signal representing channel quality data of the femto access point device, and rejecting, by the system, the request to transfer the first coupling to the second coupling.
