for operators looking to deploy a femtocell service. The

fundamental requirement for any mobile service. However,
femtocells present a very unique set of challenges, as
operators' existing networks were never designed to
support the deployment of many hundreds of thousands
of femtocells. As a result, a RAN Gateway device-to-core
network connectivity solution must overcome a number
of practical limitations in mobile networks, such as the
today's mobile networks.
large-scale femtocell deployments. However, scalability
has many dimensions: Is the address space large enough
in specific data elements to meet the deployment
requirements? Does the signaling burden of the protocol
overwhelm the core network with hundreds of thousands
of devices? How effective is the protocol/RAN gateway at
abstracting the access network from the core network? Can
network elements grow regionally as traffic increases? How
effective is the system at load balancing and redundancy?
standard, as well as existing UMA infrastructure solutions,
have already delivered robust and practical techniques for
addressing these challenges that are in commercial use
today and can be directly applied to support femtocell
deployments.
