Abstract: An example method is provided in one example embodiment and may include determining a presence of user equipment (UE) in relation to small cell radio(s) of a small cell network based on information obtained through the small cell network and one or more parallel networks; and adjusting transmit power for the small cell radio(s) based on the presence of UE in relation to the small cell radio(s). Another example method can include determining that a UE in cell paging channel mode has changed its selected macro cell radio; determining that the UE is allowed service on a small cell radio located in a vicinity of a macro cell coverage area of a selected macro cell radio; and adjusting a transmit power of the small cell radio based on a presence of the UE in a surrounding macro cell coverage area of the small cell radio.

Abstract: Embodiments include receiving one or more packets of a Wi-Fi calling session via a secure tunnel from a user device, where the user device is connected to a source network via a Wi-Fi access point. Embodiments also include determining whether the Wi-Fi calling session is a threat based, at least in part, on identifying an anomaly of at least one packet of the one or more packets. An action can be taken if the Wi-Fi calling communication is determined to be a threat. More specific embodiments include determining the at least one packet is associated with the Wi-Fi calling session by correlating information in the packet with control plane data of the Wi-Fi calling session. Further embodiments can include intercepting the one or more packets in a second secure tunnel established between an evolved packet data gateway and a service provider network associated with the user device.

Abstract: An example method is provided in one example embodiment and includes receiving a request to relocate a user equipment (UE) from a source macro radio to an ambiguous small cell access point (AP), wherein the request includes a target cell identity (ID) encoded with a source macro cell identifier for the source macro radio and a target sub-carrier identifier for the ambiguous small cell AP; determining potential target small cell APs for relocation of the first UE using the using the first target cell ID, wherein each of the potential target small cell APs are within a coverage area of the source macro radio and operate using the target sub-carrier identifier; and preparing, for each of the potential target small cell APs, a common channel to receive relocation of the first UE. The first UE can relocate to a particular target small cell access point using the common channel.
