    Abstract: Forward error correction scheduling techniques for an improved radio link protocol used in a wireless communication system, such as EV-DO. In one embodiment scheduling of the generation of repair symbols encoded to be transmitted along with source data is described. In another embodiment acknowledgment messages from a receiver are used to control the trailing edge of the protection window offered by the repair symbols. In another embodiment, non-acknowledgment messages from a receiver are used to control the generation of extra repair symbols. In another embodiment, a length field is used to avoid transmission of padding bytes over the air. In yet another embodiment, a symbol auxiliary field is appended to source symbols to indicate the padding bytes needed for symbol aligning thus avoiding the transmission of padding bytes over the air.

    Abstract: A bundler utility of a client accomplishes an objective of binding/aggregating two or more network interfaces at an application layer to increase bandwidth that the application layer can use. This interface is determined by the longest prefix match in the routing table of the device. Rather than imposing a change to the IP stack, the bundler utility presents a solution to the link aggregation problem that can be deployed without requiring any change to the client software (e.g., no browser change) and without requiring changes on the web servers.

    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: Techniques for access channel load management in a wireless communication system are described. In an aspect, the load of the access channel may be controlled by having each terminal regulates its use of the access channel (e.g., its rate of system access) based on a rate control algorithm (e.g., token bucket). The rate control algorithm may maintain information on past activities of a terminal and may regulate the use of the access channel by the terminal based on its past activities in order to control the access channel load and achieve fairness. The system may determine (312) at least one parameter value for the rate control algorithm based on load conditions and may broadcast (314) the at least one parameter value to terminals. Each terminal may regulate (318) its use of the access channel based on the at least one parameter value received from the system (316).

    Abstract: Methods, apparatus and media for receiving emergency broadcast information in a broadcast-multicast service of a communication system. The methods, apparatus and media include scheduling a broadcast of emergency broadcast information in designated control channel cycles for designated subscriber stations. The control channel cycles are transmitted with the designated control channel cycles including the emergency broadcast information. Subscriber stations awake according to their designated control channel cycle and receive the transmission of their designated control channel cycle on a broadcast-multicast service. The subscriber station determines if emergency broadcast information is in the control channel cycle assigned to the subscriber station and responds accordingly.
