    Abstract: Systems and methodologies are described that facilitate providing physical cell identifier (PCI) assignment. Neighboring access point parameters can be collected and transmitted to a PCI assigning component, which can generate a PCI based on the parameters as well as other local parameters. The neighboring access point parameters can be received by evaluating signals transmitted by the neighboring access points, from a UE communicating with the neighboring access points, over a backhaul link, etc. The parameters can include signal strength, identification, and/or the like. In addition, prioritized lists of PCIs can be provided to an access point, which can utilize the neighborhood parameters to select an optimal PCI from the list.

    Abstract: Techniques for enhanced backhaul flow control are provided. In an exemplary embodiment, a backhaul control system is described that comprises a base station controller (BSC), a backhaul network, and a base transceiver station (BTS). Each is responsive to data and messaging transmitted and received. In one aspect, the BTS includes a queue and a controller. The amount of data in a queue is adjusted by a controller based upon calculating a target queue size value. The controller non-uniformly adjusts the amount of data in a queue based upon a target queue size value which is based upon communication system parameters. The target queue size and amount of data in a queue is adjusted so as to reduce buffer underrun, decrease system latency, and increase communication system throughput.

    Abstract: Local breakout is provided by one or more nodes (e.g., a local access point and/or a local gateway) in a wireless network to facilitate access to one or more local services. In conjunction with local breakout, multiple IP points of presence relating to different levels of service may be provided for an access point. For example, one point of presence may relate to a local service while another point of presence may relate to a core network service. IP point of presence may be identified for an over-the-air packet to indicate a termination point for the packet. Also, different mobility management functionality may be provided at different nodes in a system whereby mobility management for a given node may be provided by a different node for different types of traffic. Thus, an access terminal may support multiple NAS instances. In addition, different types of paging may be provided for different types of traffic. Furthermore, messages associated with one protocol may be carried over another protocol to reduce complexity in the system.

    Abstract: Relays can be used to facilitate communication of a packet, such as from a base station to a mobile device. The packet can include a header that designates an intended destination for the packet. The header can transfer such that the intended destination designation can be sent with or without being decompressed at a relay. If there is more than one relay involved in communication, then the header can configure such that the header is accessible without performing decompression. However, if there is one relay stop, then the header can compress the designator in such a way that decompression should occur.

    Abstract: In a particular embodiment, a method is disclosed that includes receiving a feedback message at a transmitter, the feedback message including an indication of a magnitude of congestion and a sustainable rate of data transmission at a receiver. The method also includes determining a decongestion rate and a decongestion time based on at least one of the sustainable rate of data transmission and the magnitude of congestion when the magnitude of congestion satisfies a threshold value. The method further includes sending data at the decongestion rate from the transmitter to the receiver for the decongestion time. The method also includes adjusting a data transmission rate at the transmitter to the sustainable rate of data transmission after the decongestion time is ended.

    Abstract: An access point is configured based on acquired information. An access point may be configured based on the configuration(s) of at least one other access point. An identifier to be transmitted by an access point may be selected based on the identifier(s) transmitted by at least one other access point. An access point may configure itself with assistance from a configuration server. For example, the access point may send information such as the location of the access point to a configuration server and the configuration server may respond with a list of neighboring access points for that access point. A configuration server may provide configuration information to an access point based on the location of the access point. A configuration server also may direct an access point to a different configuration server.

    Abstract: Methods, apparatus, systems and computer program products are defined that provide multiple bindings in a Mobile Internet Protocol (MIP) network environment. The multiple bindings that are established are independent of one another, such that a forward link binding is decoupled from, or otherwise does not affect, a reverse link binding and vice versa. Multiple reverse link-only bindings may be established within an active route set for an access terminal. Additionally a single primary binding may be estab-lished that provides a forward link binding and reverse link binding. At any point in time, the access terminal may maintain only one primary binding. The present invention for establishing multiple link bindings may be applied to communication networks such as an Ultra Mobile Broadband (UMB) network or any other network relying on Mobile Internet Protocol (MIP) for data transmission and/or signaling transmission. Other exemplary systems include CDMA (CDMA 2000, EV DO, WCDMA), OFDM, or OFDMA (Flash-OFDM, 802.20, WiMAX), FDMA/TDMA (GSM) systems using FDD or TDD licensed spectrums, peer-to-peer (e.g., mo-bile-to-mobile) ad hoc network systems often using unpaired unlicensed spectrums, and 8O2.xx wireless LAN or BLUETOOTH techniques.
