  • Publication number: 20120094663
    Abstract: Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macrocell communications for a mobile device. A mobile device may perform an out-of-band (OOB) search for the femtocell, the OOB search triggered by a proximity detection configuration command from the macrocell. The mobile device may wirelessly communicate with a located femtocell via an OOB link, and receive femtocell information from the femtocell via the OOB link. The mobile device may transmit the received femtocell information to the macrocell. The macrocell may generate instruction for a mobile device search based on the femtocell information. The macrocell may transmit such instructions to the mobile device for an in-band search for the femtocell.

  • Publication number: 20120094665
    Abstract: Methods, systems, and devices are described that may provide for femtocells to indicate the proximity of mobile user equipments and/or provide mobile identity to assist in resolving femtocell disambiguation. A femtocell may detect a user equipment in its proximity using an out-of-band link. The femtocell may transmit a proximity indication message to a macro network controller via a core network. The macro network may direct the user equipment to perform a variety of tasks, including directing the user equipment to do a handover to the femtocell. Some embodiments may utilize existing user equipment registrations and femto-to-macrocell outbound handover procedures to address problems such as femtocell ambiguity resolution and triggering frequency searches at a macro network when a current macrocell signal strength is good. These embodiments may utilize dummy identifiers to register the user equipment to facilitate addressing these problems.

  • Publication number: 20120072751
    Abstract: A scheme is provided for conserving power in client terminals and/or reducing latency in wireless systems by using a proxy device. The client terminal may have a primary communication interface for communications with an access node and a secondary communication interface to communicate with the proxy device. The client terminal may indicate to the access node a short cycle rate for monitoring its signaling/control channel(s). The client terminal may the power off its primary communication interface without informing the access node. Prior to powering off its primary communication interface, the client terminal may assign the proxy device to act as its proxy and monitor the signaling/control channel with the access node. The proxy device monitors the signaling/control channel(s) according to the indicated short cycle rate. Upon detection of a message for the client terminal, the proxy device forwards the message to the client terminal via a secondary communication interface.

  • Publication number: 20120069827
    Abstract: A novel power conservation scheme is provided for conserving power in client terminals by using a proxy server. The client terminal may have a secondary communication interface for short range communications and a primary communication interface for long range communications with an access point for a wireless network. To conserve power, the client terminal may power down its primary communication interface without informing the access point. The access point assumes the primary communication interface is still active. Prior to shutting off its primary communication interface, the client terminal may assign an external proxy device to act as a proxy and monitor its data channel with the access point. The proxy device monitors the data channel(s) for the client terminal via a primary communication interface. If the proxy device detects a data message for the client terminal, it forwards the data message to the client terminal via a secondary communication interface.

  • Publication number: 20120072609
    Abstract: Wireless video transmissions over a MAC layer employ various techniques to improve throughput which may negatively impact latency, such as Block-ACK and data aggregation. To improve latency while continuing to improve throughput, data packets are fenced according to application layer specifications and then transmitted. For video data, Block-ACK sequences and aggregation sequences are terminated at the end of video frames or video slices. For data aggregation, a physical layer data packet concludes at the end of a video frame or slice. The application layer can indicate to the MAC layer when such packet fencing is to occur. In use with 802.11n transmission a data flag may be used by the MAC layer to facilitate fencing.

  • Publication number: 20120069801
    Abstract: Systems, methods, devices, and computer program products are described for handling of access terminals on an out-of-band piconet within a femto-proxy architecture. A femto-proxy system includes a femtocell (a femto access point, or FAP) and one or more out-of-band (OOB) proxies. One of the OOB proxies is configured to act as a master of an OOB piconet, through which various services are provided, including services to support the femtocell operation of the femto-proxy system. For example, the OOB piconet is used to facilitate lower power access to the macro communications services provided through the femtocell. In some cases, a combination of connected and inactive OOB operational modes are used to support an expanded number of slave access terminals on the piconet, where some of those slaves are operating in an active WWAN mode and others are operating in an idle WWAN mode. For example, parked mode may be used for idle WWAN mode access terminals.

  • Publication number: 20120046025
    Abstract: Out of band (OOB) communication facilitates femtocell operation. One or more proximity agent provides out of band communication with nodes (e.g., mobile client devices) to provide assistance in or otherwise facilitate femtocell discovery, reselection, and/or interference mitigation. Out of band communication techniques provide for low power discovery, association, and communication as compared to corresponding femtocell or cellular network communication techniques. An OOB proximity agent is provided in association with a femtocell to provide transmit power level control with respect to the femtocell. In operation, if a client device searches for and finds an OOB proximity agent, it will find a femtocell, thereby avoiding a need to aggressively search for femtocells.

  • Publication number: 20110263242
    Abstract: Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile access terminals. An out-of-band (OOB) link is used to detect that an access terminal is in proximity of a femtocell (e.g., using an OOB radio integrated with the femtocell or in a common subnet with the femtocell). Having detected the access terminal in proximity to the femtocell, an OOB presence indication is communicated to a femto convergence system disposed in a core network in communication with the macro network to effectively pre-register the access terminal with the femto-convergence system. When the femto convergence system receives a handoff request from the macro network implicating the pre-registered access terminal, it is able to reliably determine the appropriate target femtocell to use for the hand-in according to the pre-registration, even where identification of the appropriate target femtocell would otherwise be unreliable.

  • Publication number: 20110263258
    Abstract: Systems, methods, devices, and computer program products are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile access terminals. A femto-proxy system is provided including a femtocell and an out-of-band (OOB) proxy. While the femtocell may be addressed by the macro network according to a potentially non-unique identifier (e.g., its PN offset), the OOB proxy is addressable according to a unique OOB identifier (e.g., a Bluetooth device address, BD_ADDR). When the mobile access terminal is in proximity to the femto-proxy system, it detects the OOB proxy and communicates the unique OOB identifier to the core network via the macro network (e.g., as part of a measurement report). The OOB identifier is mapped (e.g., in the core network) to the femtocell, allowing the core network to uniquely identify the appropriate target femtocell for active hand-in.
