Abstract: The disclosure provides for a user equipment (UE) to change from a first network to a second network for an internet protocol (IP) multimedia subsystem (IMS) call. Initially, the UE has a connection to a first network providing an IP address for the UE. The UE may receive, via the first network, a message indicating an incoming IMS call. The UE may transmit one or more IMS call setup messages on the first network at an IP layer. The UE may change the connection from the first network to a second network that uses a same identifier for the UE (e.g., the IP address). The UE may complete setup of the IMS call on the second network using the same identifier for the UE.

Abstract: A neutral home network (NHN) may support home-routed traffic between a user equipment (UE) and a network of a mobile network operator (MNO) associated with the UE. The NHN may transmit an access point name (APN) that indicates a public land mobile network (PLMN) identifier (ID) to the UE. If the NHN supports home-routed traffic, the NHN may transmit an APN that indicates an MNO PLMN ID. If the NHN does not support home-routed traffic, the NHN may transmit an APN that indicates an NHN PLMN ID. From the APN, the UE may determine whether the NHN supports home-routed traffic. If the NHN supports home-routed traffic, the UE may transmit a packet data network (PDN) connectivity request to the NHN. If the NHN does not support home-routed traffic, the UE may establish a tunnel to the MNO network through Internet access provided by the NHN.

Abstract: The present disclosure presents a method and an apparatus for heavy active estimation mechanism for backhaul management at a small cell base station. For example, the method may include identifying, at the small cell base station, that a throughput of a user equipment (UE) in communication with the small cell base station is potentially limited due to backhaul congestion at the small cell base station, establishing a proxy flow between the small cell base station and a transmission control protocol (TCP) proxy peer in response to the identifying, wherein the proxy flow data packets are transmitted from the small cell base station to the TCP proxy peer or from the TCP proxy peer to the small cell base station, calculating a throughput of the proxy flow for a pre-determined time period, and determining whether the throughput of the UE is limited by backhaul congestion at the small cell base station based on the calculated throughput of the proxy flow. As such, heavy active estimation mechanism for backhaul management at a small cell base station may be achieved.

Abstract: Fractional frequency reuse (FFR) is defined based on a mobility condition of an access terminal. For example, upon determining that an access terminal is moving (or at a cell edge, or experiencing poor link conditions, etc., due to mobility), FFR may be defined for the serving access point of the access terminal and/or for neighbor access points to maintain acceptable link quality for the access terminal. In particular, FFR may be defined in a manner that frees-up or otherwise reserves resources for the access terminal. For example, the serving access point may allocate additional sub-bands for the access terminal and/or increase the power levels used on the sub-bands allocated for the access terminal. In addition, neighbor access points may back-off these sub-bands.
