Abstract: 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.

Abstract: The soft state of a header compression scheme in a communication system carrying packet traffic including a real time communication signal can be updated (63) during periods of communication signal inactivity (62), during which there is no need to transmit the communication signal. The header compression soft state can also be updated by stealing bits (83, 84) from the communication signal to carry the header update information (73). If the communication signal includes source encoded data, the header compression soft state can be updated selectively (126) based on the bit rate (122, 124) of a codec that produced the source encoded data.

Abstract: In the area of network provisioning, there is a problem of selecting a suitable traffic-provisioning model for large networks due to the high management complexity of the resource-efficient trunk model and the poor bandwidth efficiency of the easy-to-configure hose model. The invention is based on the idea of partitioning at least part of the network into multi-node clusters, and defining traffic limitations on at least two levels, including the intra-cluster level and the inter-cluster level, where the traffic limitations include one or more node-to-cluster traffic limitations for inter-cluster traffic. Subsequently, cluster-based provisioning of the network is performed based on the traffic limitations. The novel node-to-cluster limitations proposed by the invention are preferably applied in a cluster-based trunk or hose model on the inter-cluster level. In other words, for the description of the inter-cluster traffic (traffic between the clusters) cluster-based trunk or hose models can be used, preferably depending on the available information about the traffic. The cluster-based provisioning makes it possible to find a trade-off between management complexity and overprovisioning.

Abstract: Information about virtual private networks—VPNs—in each domain of a multi-domain communications system is provided. By comparing a request for a configuration of a VPN with the provided information of other connected domains, a match can be found. VPN configuration can then be performed based on the outcome of the match. The provided domain VPN information is in one embodiment spread to other domains under constrictions put by SLAs between domain operators. The spreading of VPN information can be performed regularly or triggered by an external event. In another embodiment, the VPN configuration request is instead spread to different domains.

Abstract: The bandwidth utilization and transmission efficiency associated with the point-to-point transportation of internet protocol (IP) data packets in a network environment is improved by employing asynchronous transfer mode (ATM) adaptation layer two (AAL2) minicells as a bearer. Bandwidth utilization and transmission efficiency may be further enhanced by mapping one or more data fields from the header portion of the IP data packets into one or more look-up tables and then transporting the look-up table addresses in the AAL2 minicell headers rather than the data associated with the one or more data fields in the 1P data packet headers.
