Femtocell integration into the macro network

Abstract

Some embodiments of the invention provide a communication system that includes a first communication network, a second communication network, and a core network. The second communication network includes a network controller and a group of two or more access areas that are communicatively coupled to the core network by the network controller. Some embodiments service the second network access areas by providing access area identifiers to each access area while communicating with the first network or core network using a single area identifier assigned to the network controller. Some embodiments provide access control by sending a series of invalid messages to a user equipment (UE) that is not authorized to access services of the second network to reject the UE. Some embodiments reject the UE by sending a message to ban a UE from an access area with a particular access area identifier.

The problem with landline connections is that it limits user mobility

Thus, this approach provides a higher quality service at a lower cost, but the service only extends to a modest distance from the base station
