20080212575 | Codec Rate Adaptation as a Function of Air-Interface as Wel as Network in a Packet-Based Network - Codec rate adaptation for wireless circuit-switched voice communications routed through a packet-based network. A Mobile Station (MS) preferably with Circuit Switched services participating in a voice communication with a distant terminal transmits an initial CMR identifying an initial maximum speech coding rate selected as a function of a downlink radio quality. At each intermediate network node, one or more operational parameters are determined by using an Explicit Congestion Notification (ECN) protocol. When a CMR is received at each network node, if the operational parameters are not within a predetermined range suitable for the transmission of speech packets through the network using the initial maximum speech coding rate the maximum speech coding rate identified in the CMR is reduced as a function of the operational parameters and then forwarded toward the distant terminal. | 09-04-2008 |

20100250930 | METHOD AND APPARATUS FOR PROTECTING THE ROUTING OF DATA PACKETS - A method and apparatus for protecting the routing of data packets in a packet data network. When a first end-host sends an address query to a DNS server system regarding a second end-host, the DNS server system responds by providing a destination parameter containing an encrypted destination address associated with the second end-host. Thereby, the first end-host is able to get across data packets to the second end-host by attaching the destination parameter to each transmitted data packet. A router in the packet data network admits a received packet if a destination parameter is attached to the pocket including a valid destination address encrypted by a key dependent on a distributed master encryption key. Otherwise, the router discards the packet if no such valid destination address can be derived from the packet by applying decryption to the destination parameter. | 09-30-2010 |
