INBOUND HANDOVER FOR MACROCELL-TO-FEMTOCELL CALL TRANSFER
First Claim
1. A system, comprising:
- a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising;
receiving femtocell data that comprises a scrambling code and timing data for a user equipment to define a time period during which the user equipment is authorized to access a femtocell device;
generating, based on the femtocell data, neighbor list data related to macro cell devices that satisfy a criterion associated with distance data; and
transferring a first coupling between the user equipment and the system to a second coupling between the user equipment and the femtocell device based on the neighbor list data.

Abstract
A system and methodology that facilitates macrocell-to-femtocell handovers during an on-going communication session by augmenting a neighbor list with femtocell data is provided. Moreover, the femtocell data associated with a set of femtocells that the a user equipment (UE) is authorized to access is added to a neighbor list. When a handover is initiated, the femtocell data is utilized to facilitate scanning of a radio environment of the user equipment to detect a target cell site for the handover. In one aspect, location data and/or serving cell data associated with the set of femtocells is utilized to limit the number of femtocells that are added to the neighbor list.

8. A method, comprising:
-
determining, by a network device comprising a processor, femtocell data that comprises a scrambling code and timing data for a mobile device to define a time period during which the mobile device is authorized to access a femtocell device; generating, by the network device, neighbor group data, related to a group of network devices that are within a defined distance from the network device, based on the femtocell data; and transmitting, by the network device, the neighbor group data to the mobile device to facilitate transferring a first coupling between the mobile device and the network device to a second coupling between the user equipment and the femtocell device. - View Dependent Claims (9, 10, 11, 12, 13)

14. A machine-readable storage medium comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
-
receiving, from a network device, neighbor list data indicative of network devices within a defined distance from a user equipment; receiving, from a base station device, femtocell data that comprises a scrambling code and timing data for the user equipment that specifies a time period during which the user equipment is authorized to access a femto access point device; augmenting the neighbor list data with the femtocell data; and transferring, based on the neighbor list data, a first coupling between the user equipment and the base station device to a second coupling between the user equipment and the femto access point device. - View Dependent Claims (15, 16, 17, 18, 19, 20)
