Abstract: An inter-cell interference coordination procedure in heterogeneous networks (HetNets) is enhanced based on utilization of cell profile data associated with neighbor access points to improve HetNet spectrum efficiency, mobility performance, and/or overall network capacity. In one aspect, a macro access point can receive cell profile data associated with neighbor access points and modify a power level of reduced-power almost blank subframes (ABS) transmitted by the macro access point to manage macro cell capacity. Further, the macro access point can configure the ABS pattern and transmit the ABS pattern to the neighbor access points. Based on the ABS pattern, the neighbor access points can schedule transmissions to user equipment that are located at (or close to) their cell-edge to reduce inter-cell interference.

Abstract: Concepts and technologies disclosed herein are directed to service aware carrier aggregation. According to one aspect disclosed herein, an eNodeB (“eNB”) can learn, via a primary serving cell (“PSC”), that a user equipment (“UE”) has a capability to utilize a carrier aggregation feature. The eNB can receive policy information and service information, and can learn, via the PSC, a service requested by the UE. The eNB can determine, based at least in part upon the policy information, the service information, and the service, whether to implement the carrier aggregation feature to provide the service to the UE. When the eNB determines that the carrier aggregation feature is to be implemented, the eNB can inform the UE to reconfigure a radio resource control (“RRC”) configuration to include the PSC and a secondary serving cell (“SSC”). The eNB can allocate physical media resources for the service from the PSC and the SSC.

Abstract: A user equipment device cell reselection procedure includes scaling factors that are based on cell-types of a camping cell and neighbor cells and a mobility state of the user equipment device. The scaling factors can be received in a system information block message. During an idle mode cell selection/reselection procedure, the user equipment device can apply the appropriate scaling factor to the hysteresis during the cell selection/reselection procedure.

Abstract: A mobile device mobility state is included in device reporting to a radio access network for mobility event and load balancing purposes. Respective load conditions and respective coverage areas of a first set of devices of a first network and a second set of devices of a second network are analyzed. In addition, a mobility state of a mobile device, a first signal strength associated with the first set of devices, and a second signal strength associated with the second set of devices are also analyzed. The mobility state is a function of a movement pattern of the mobile device and a speed at which the mobile device is being moved. Network traffic of the mobile device is routed to a set of network devices selected from the first set of devices and the second set of devices, as a result of the analysis.

Abstract: Load balancing is facilitated utilizing geographical location and mobility speed. An example method includes receiving, by a first cell device including a processor and associated with a first cell, from a device of devices, information indicative of whether the device has detected cell type information from a second cell device associated with a second cell, wherein at least a portion of the second cell is located within a first boundary of the first cell. The method also includes: determining, by the first cell device, a mobility characteristic of the device, wherein the devices comprise respective mobility characteristics; and selecting, by the first cell device, the device of the devices to associate with the second cell based on the mobility characteristic of the device.

Abstract: Local breakout mechanisms can be performed by a femto access point (FAP) to facilitate efficient utilization of backhaul and/or macro networks. In particular, a slave Gateway GPRS Support Node (GGSN) can be integrated within the FAP to directly route the incoming traffic from a user equipment (UE) at the FAP. In one example, Internet bound traffic can be directly routed to the Internet, without employing macro network resources. Further, the system can avoid hairpinning by routing traffic between the UE and a home Local Area Network (LAN) by a anchoring a call or a session in the slave GGSN and facilitate integration of UEs with home applications by employing a UE Digital Home Agent. In addition, the FAP can perform UE-to-UE CS media breakout to facilitate communication between UEs attached to the FAP, without routing the traffic through the core macro network.
