    Abstract: Systems and methodologies are described that facilitate multiplexing communications from multiple downstream access points to one or more mobility management entities (MME). In particular, a concentrator component is provided that can establish a single transport layer connection with an MME along with multiple application layer connections over the single transport layer connection for each of multiple downstream access points and/or related mobile devices. The downstream access points and/or mobile devices can provide identifiers to the concentrator component, which can utilize the identifiers to track communications with the MME. In this regard, the MME can additionally include identifiers received from the concentrator component in subsequent communications to facilitate identifying the appropriate downstream access point and/or mobile device.

    Abstract: Techniques for transmitting information in a wireless network are described. In an aspect, information may be conveyed based on specific resources used to send a signal, e.g., a pilot. A pseudo-random function may receive the information to convey via the signal and possibly other information and may provide pseudo-random values, which may be used to select the resources to use to send the signal. In one design, a transmitter (e.g., a base station for a sector) may determine first information (e.g., a sector ID) to convey via a pilot and may also determine second information for absolute time (e.g. a pilot cycle index). The transmitter may determine resources (e.g., slots) to use to send the pilot based on the first and second information and possibly based further on a PN offset assigned to the sector. The transmitter may transmit the pilot in the determined resources.

    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 IP access is provided in a wireless network to facilitate access to one or more local services. In some implementations, different IP interfaces are used for accessing different services (e.g., local services and operator network services). A list that maps packet destinations to IP interfaces may be employed to determine which IP interface is to be used for sending a given packet. In some implementations an access point provides a proxy function (e.g., a proxy ARP function) for an access terminal. In some implementations an access point provides an agent function (e.g., a DHCP function) for an access terminal. NAT operations may be performed at an access point to enable the access terminal to access local services. In some aspects, an access point may determine whether to send a packet from an access terminal via a protocol tunnel based on the destination of the packet.

    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.
