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.

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: Techniques provide for converged wireline and wireless services in part by employing a set-top box (STB) with machine-to-machine (M2M) communication. The STB, associated with an access point, such as a femtocell, can be used to send/receive messages, including video, to/from user equipment (UE) via a core network. A monitoring system includes a sensor component that is triggered under specified conditions, and the STB records events in response to the trigger, where a recorded event can be sent as a message to the UE. The STB or associated remote control can indicate a received message to a user, who can view the message on the STB, remote control, or associated television. A meter component is associated with the STB via the femtocell or other desired connection. The STB can receive and store utility meter readings for validation or dispute by the user.

Abstract: Aspects of the subject disclosure include, for example, identifying a primary serving cell and a secondary serving cell, wherein the primary serving cell facilitates one of attachment, re-attachment or mobility, or any combination thereof, of a mobile device in association with coordination of a wireless service between the primary serving cell, the secondary serving cell and the mobile device. A latency value associated with a message exchange is determined between the primary and secondary serving cells via a messaging interface, and compared to latency requirements, which correspond to a group of mobile service features. A mobile service feature of the group is associated with the wireless service based on the comparison. The wireless service includes a coordinated exchange of wireless signals between the primary serving cell and the mobile device and between the secondary serving cell and the mobile device based on the mobile service feature. Other embodiments are disclosed.
