Devices, systems, and methods are disclosed to directly connect a node of a Radio Access Network (RAN) with an Internet Protocol (IP) network. The node is provided with an interface to a broadband local loop network. Access to the local loop network or last mile enables the node to communicate directly with an IP network, including an IP Multimedia System (IMS) core. The node need not access a packet-switched core network via a controller. Embodiments include a Node B with an IP interface in a UMTS system and a Base Transceiver Station (BTS) with an IP interface in a GSM system.
