    Abstract: The described method provides for an efficient method for user equipment (104) to identify when it is in proximity to an assigned femtocell (108) in order to be handed over to a femtocell from a macro cell. As the user the equipment moves within a macro cell (106) that is defined by a serving base station (102), it is determined (202) that it is in the range of or in proximity to the femtocell to which it is registered or subscribed. Upon notification that it is near the femtocell, the user equipment sends (204) a message to the serving base station of the macro cell indicating the user equipment has identified its femtocell. The serving base station then sends (208) a message to femtocell to turn on the femtocell so that a handover of the user equipment from the macro cell and serving base station and the femtocell can be initiated. The serving base station sends (212) a response to the user equipment indicating that the femtocell is ready to receive the user equipment as a part of handover procedure.

    Abstract: Methods and apparatus for routing messages between an end node and an access node via another access node are described. Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node with which it has an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.

  • Patent number: 8977265
    Abstract: A method for minimizing handoff latencies when a handoff is performed in a wireless network. An access point (AP) or base station associated to a current wireless station (STA) allows information required for a reassociation to the STA to be propagated to handoff-capable neighboring APs or base stations. When the STA moves, a neighboring AP or base station performs the reassociation to the STA on the basis of context. When a handoff procedure is performed, the time taken to receive context of a corresponding STA is reduced, such that a fast handoff can be implemented.

  • Patent number: 8971888
    Abstract: Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.

  • Patent number: 8971295
    Abstract: Various embodiments enable a device to maintain a plurality of connections to a plurality of wireless networks simultaneously using one radio. For instance, a device can partition in time, or “time-slice”, when it transmits and receives data such that a device can maintain a plurality of connections with a plurality of networks concurrently. With the plurality of connections, the device can receive multiple copies of data. In some embodiments, a device can compare multiple copies of data and determine which copy of data is a best representation. Once a best representation has been determined, it can be selected for further usage.

  • Patent number: 8965379
    Abstract: A RAN may receive a call establishment request, on a first frequency, seeking to establish a call involving a WCD. In response to receiving the request, the RAN may select a plurality of wireless coverage areas, each defined using the first frequency. The RAN may determine that utilization of a first wireless coverage area of the selected wireless coverage areas meets a utilization threshold. In response, the RAN may determine that a strength at which the WCD receives signals from the first wireless coverage area exceeds the strengths at which the WCD receives signals from other wireless coverage areas in the plurality of wireless coverage areas by at least a signal strength differential value. Accordingly, the RAN may assign, to the WCD, a traffic channel from a second wireless coverage area, defined using a second frequency, for supporting the call.

  • Patent number: 8958838
    Abstract: Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.

  • Patent number: 8954077
    Abstract: Access control for an access point (e.g., a cell of the access point) may be based on an access mode associated with the access point. For example, depending on the access mode, access control may involve performing a membership check for the access point. Such a membership check may be performed at a network entity, a source access point, or some other suitable location in a network. In some aspects, access control may involve performing a membership check for an access point in conjunction with a context fetch procedure. Such a procedure may be performed, for example, when an access terminal arrives at the access point after experiencing RLF at another access point.
