In certain embodiments, network nodes 315 may interface with a radio network controller. The radio network controller may control network nodes 315 and may provide certain radio resource management functions, mobility management functions, and/or other suitable functions. In certain embodiments, the functions of the radio network controller may be included in network node 315. The radio network controller may interface with a core network node. In certain embodiments, the radio network controller may interface with the core network node via an interconnecting network 320. Interconnecting network 320 may refer to any interconnecting system capable of transmitting audio, video, signals, data, messages, or any combination of the preceding. Interconnecting network 320 may include all or a portion of a public switched telephone network (PSTN), a public or private data network, a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a local, regional, or global communication or computer network such as the Internet, a wireline or wireless network, an enterprise intranet, or any other suitable communication link, including combinations thereof.

In some embodiments, the core network node may manage the establishment of communication sessions and various other functionalities for UEs 310. UEs 310 may exchange certain signals with the core network node using the non-access stratum layer. In non-access stratum signaling, signals between UEs 310 and the core network node may be transparently passed through the radio access network. In certain embodiments, network nodes 315 may interface with one or more network nodes over an internode interface, such as, for example, an X2 interface.
