    摘要: The present invention allows content to be delivered to a mobile terminal over different types of networks in order to efficiently use network resources. Content can be delivered using a select delivery method over a cellular network, a local wireless network, or a broadcast network. Within any of the networks, the content may be unicast to individual mobile terminals using individual content flows, multicast to a group of mobile terminals, or broadcast to any or all of the mobile terminals. Content can be multicast or broadcast to mobile terminals via different ones of the disparate networks. During a content flow, the network through which the content flow is delivered may be changed to allow the mobile terminal to receive the content through a different network. Further, the delivery method used to deliver the content may dynamically change as the number of mobile terminals receiving or requesting the content changes.

    摘要: A Dynamic Frequency Association (“DFA”) techniques comprising fixed channel allocation (“FCA”) and distributed channel borrowing techniques using a segregation scheme is described. The DFA technique can be used autonomously to dynamically determine the best channels for a cell cluster. Additionally, a method of minimizing search delays at channel assignment by employing a channel usage history is disclosed. In one aspect, as in FCA, each cell is assigned its nominal channels, if any, from the available frequency spectrum, with a fixed radio assigned to each of these frequencies, respectively. Additionally, in accordance with the teachings of the present invention, each cell is equipped with one or more radios designated as “DFA radios”. In operation, idle DFA radios scan channels that may be borrowed in order to build a probability matrix. This enables the cell to determine which channels to use for traffic prior to actual channel request by a mobile. This reduces the search delay experienced in classic segregation schemes.

    摘要: Systems and methods for packet re-transmission in multi-hop wireless networks are provided. RLP packet re-transmission only starts from the hop where L1 ARQ fails. This results in an increased efficiency of radio resource utilization. The benefit increases with a larger number of hops. In particular, the benefit is greatest for implementations where the last hop is more unstable than the remaining hops. This is the case for the cellular downlink where the last hop is between a relay and a mobile terminal, and this hop is typically the most unstable. However, applications are not limited to this particular case. The improvement in RLP recovery delay can be translated into an improvement in system capacity and per-terminal throughput. A short RLP recovery delay enables the possibility of a higher number of re-transmissions of lost RLP packets. This in turn translates into a higher target physical layer FER (frame error rate) being allowed which in turn translates into an increased system capacity. Furthermore, a short RLP recovery delay may reduce the possibility of TCP re-transmission and slow start.

    摘要: Some embodiments of the invention provide an implementation for a multi-hop wireless backhaul network. These embodiments can advantageously be deployed in dense urban areas and/or co-located with wireless access nodes, such as base-stations of a cellular wireless communication system. Preferably wireless links between constituent network nodes are set-up hierarchically. A basic result of this is that peer-to-peer (child-to-child) communication is generally prohibited and circuits are forced to conform to a topology. The multi-hop wireless backhaul network may be used to carry delay sensitive, high-density last mile circuit traffic over Non-Line-Of-Sight (NLOS) broadband radio links. Moreover, some embodiments of the invention provide a method of path-healing for re-routing of circuit traffic from circuits that have experienced catastrophic failures.
