    摘要: A method and apparatus for bandwidth aggregation for an Internet protocol (IP) flow are disclosed. A sender may split IP packets on a single IP flow, and transmit the IP packets to a receiver via at least two interfaces. The sender splitting the IP packets over multiple interfaces may not send any signaling to the receiver. Alternatively, the sender may send information to the receiver for configuring distribution of the IP packets over multiple interfaces. The information may be carried on a binding update message, a binding acknowledgement message, or a binding refresh request message. The IP packets may be split and transmitted by a logical interface that sits between an IP layer and a layer 2, or by a bandwidth aggregation (BWA) middleware located between a transmission control protocol (TCP) layer and an IP layer.

    摘要: A method for reducing overhead when transmitting and receiving an Internet Protocol (IP) packet by a device begins with receiving of the IP packet by the device. In the packet, an IP address of the packet has been removed and replaced with a watermarking signature based on the IP address. The IP address is obtained using the watermarking signature. The IP address is attached to the packet and the packet is forwarded by the device to a destination over a network using the IP address.

    摘要: A method and apparatus for supporting handover of mobile communications is provided. A router performs routing services in a service area. The router maintains a location table configured to store current router addresses of mobile nodes that have the router as a home router. The router receives data intended for mobile nodes that are listed in the location table and are in the routers service area. The router receives a user datagram protocol (UDP) message from a mobile node when it leaves the service area. The UDP message includes an IP address of a new router in the mobile node's new service area. The router updates the location table with the new IP address and transmits data intended for the mobile node to the new router until the data is redirected at the source.

    摘要: A method and apparatus of providing a piggybacked positive acknowledgement/negative acknowledgement (ACK/NACK) (PAN) field indicator (PANI) and a polling indicator are disclosed. A combined field of a PANI bit, a relative reserved block period (RRBP) bit and an EGPRS supplementary polling (ES/P) field may indicate a polling scheme and a presence of a PAN field. Alternatively, the presence of the PAN field in the data block may be indicated by using a specific training sequence. Alternatively, a forward error correction (FEC) coding may be performed on the data block including the header, and the presence of the PAN field may be indicated by scrambling the encoded bits corresponding the header with a specific scrambling sequence. Alternatively, a header check sequence (HCS) may be generated and the presence of the PAN field is indicated by mixing a predetermined sequence with the HCS.
