    摘要： Internet protocol version 6 (IPv6) is utilized throughout the entire cellular network and employs routing headers of the packets to ensure that the packets are routed via the gateway router (GR) to the end destination which is accomplished by a user equipment (UE) specifying the IP address of the gateway router as the IP address of an intermediate router in the routing header. Packets may also be routed to UEs from the GR through an intermediate router.

    摘要： Techniques for supporting utilization of femtocell service capabilities for services are disclosed. A network device may be configured to implement a femto services gateway. The femto services gateway may reside in a femtocell and provide application programming interfaces (APIs) to services to enable applications implementing the services to make use of functionalities of femtocell service capabilities. The APIs may be a subset of or an extended set of Open Service Access Parlay or Parlay-X APIs. The services may be either femtocell-hosted, mobile APIs network operator core network-hosted, or Internet-hosted. The femtocell service capabilities may include a framework service capability feature (SCF), a call control SCF, a user interaction SCF, a mobility SCF, a terminal capability SCF, a data session control SCF, a connectivity manager SCF, an account management SCF, a charging management SCF, a policy management SCF, a presence and availability management SCF, or a multimedia messaging SCF.

    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 cancelling interference in received signals are disclosed. A receiver includes a knowledge-based interference cancellation unit, a blind interference cancellation unit and a trade-off management unit. The knowledge-based interference cancellation unit cancels interference in the received signals based on pre-known knowledge and the blind interference cancellation unit cancels interference in the received signals without the pre-known knowledge. The trade-off management unit determines a trade-off between knowledge-based interference cancellation and blind interference cancellation, whereby at least one of the knowledge-based interference cancellation and the blind interference cancellation is selectively preformed based on the trade-off. The interference cancellation may be performed by implementing at least one of a successive interference cancellation (SIC), a principal component analysis (PCA) and an independent component analysis (ICA). The knowledge-based and the blind interference cancellation may be performed in parallel, in series or in any combination.

    摘要： A method for reducing overhead when transmitting an Internet Protocol (IP) packet begins by selecting a watermarking signature based on the IP address of the packet. The watermarking signature is applied to the packet and the IP address is removed from the packet. The packet is sent to a receiver, which looks up the IP address of the packet by using the watermarking signature. The watermarking signature can be a radio frequency watermarking signature or a digital watermarking signature. A similar method employing watermarking can be used to reduce medium access control header overhead.
