A method includes requesting, by a first wireless intelligent content acceleration (WICA) unit, content from a provider and receiving, by the first WICA unit, a first transmission over a backhaul link, the first transmission being based on the request. The method also includes determining whether the first transmission includes a signature without a first block of data or the signature and the first block of data. Additionally, the method includes, upon determining that the first transmission includes the signature without the first block of data, retrieving the first block of data from a content cache in accordance with the signature, and, upon determining that the first transmission includes the signature and the first block of data, saving the signature and the first block of data in the content cache. Also, the method includes processing the first block of data.

In a wireless multi-hop relay network arranged in a tree topology, the base station and one or more relay stations are associated as a virtual base station (VBS). The base station and each relay station have a unique virtual base station identifier (VBS-ID) associated with the path defined by the base station and the one or more relay stations. A relay station in the branch uses its VBS-ID for communicating with an attached subscriber station (e.g. a mobile station) such that communications between the base station and subscriber station occur via the VBS. Subscriber station data communications are relayed between the base station and the one or more relay stations over the VBS via a tunnel connection. The VBS is auto configurable. Mobility for subscriber stations and 10 relay stations is provided through reconfiguration of VBS's.

In accordance with an embodiment, a network device has an input port for receiving input packets, and an output port for sending output packets, where the input packets and output packets have context layer information. The network device also includes a processor configured to process the input packets and output packets using a network protocol having a context layer.

A content-centric-network (CCN)/named-data networking (NDN) system to support seamless mobility for a mobile node (MN) comprising a first point of attachment (PoA) configured to indicate to the MN that attaches to the first PoA one or more neighbor PoAs and to multicast an interest for content from the MN to the neighbor PoAs in a CCN or NDN when the MN starts a handoff procedure, and a second PoA from the one or more neighbor PoAs of the first PoA configured to receive the multicast interest from the first PoA, forward the interest to the CCN or NDN, receive content data from the CCN or NDN, and forward the content data to the MN.

Middleware is provided as a control plane for WiMAX control messaging. Each ASN in a WiMAX system is associated with a Session Initiation Protocol (SIP) server. A plurality of Functional Entities (FEs) are distributed across the ASNs, wherein each FE (or a group of FEs) associated with a SIP agent. Each FE is operable to control a function associated with a subscriber station (SS). The function controlled by a first FE is transferred to a second FE by employing the SIP agents to establish a SIP session between the first and second FEs. WiMAX control messages are then exchanged over the established session to transfer the SS function from the first FE to the second FE. The first and second FEs may be in the same ASN, or the first and second FEs may be in different ASNs.

A method of performing fast base station switching for hand off is provided that involves the use of a tunnel from a serving base station to a target base station. During a hand off, packets are forwarded by the serving base station to the target base station using the tunnel. A hierarchical hand off method is also provided that uses a diversity hand off method for a hand off between base stations of different zones, and uses a non-diversity handoff, such as the fast base station switching method, for a hand off between base stations in the same zone.

A security zone key is used to secure data traffic/control messages in a multi-hop wireless relay network. In one embodiment, the security zone key is generated by a base station and passed to relay stations and optionally mobile stations that are to be associated with the security zone. A given base station may implement multiple security zones on the wireless network. The members in each zone share a unique group security association. One or more connections may be assigned to a particular security zone. Data traffic/control messages directed to relay stations in a security zone are processed using the security zone key to enable all relay nodes within the security zone to verify the authenticity of the management message and optionally decode the messages. From a management perspective, since a common security zone key is in use by all relay stations in the security zone, the management messages may be broadcast/multicast to the relay nodes in the security zone and the key distribution and management protocols have much less complexity.

Group key security in a multihop relay wireless network

A Point to Multipoint (PMP) multi-hop relay network includes a base station, one or more relay stations and one or more subscriber stations. Active service flows in a PMP multi-hop relay network have a 16-bit connection identifier (CID). A CID defines the connection that a packet is servicing. Before traffic can be transmitted, the path through the network, and the association of CIDs with respective hops needs to be established. The CID mapping relationship from the ingress air link to the egress air link at each relay station is first set up, which is then followed by a traffic phase where the CID mapping relationship is used to route traffic from a base station to a subscriber station.
