Abstract: Disclosed is a method related to the controlling of quality of services of a CDMA-based-System. It is provides an improved control mechanism for the quality of services in a CDMA-System, in particular by providing a controlling means apt to assign the target signal to interference ratio, the static rate matching factor and the power-offset dynamically, especially adapted to be used for UMTS-Systems.

Abstract: Flexibly configurable layer one transport channels produce radio blocks in response to communication information and extract communication information from radio blocks. One of the transport channels can be enabled to extract its associated communication information from a radio block while another of the transport channels is maintained disabled. The one transport channel provides the extracted communication information to a decision maker in a higher layer. In response to the extracted communication information, the decision maker decides whether the other transport channel should be enabled, and provides to the physical layer an indication of its decision.

Abstract: A communication system is disclosed that comprises first and second communication apparatus. The first communication apparatus is provided with a transmitter for each of the transmission paths, which are capable of sending at least part of a communication signal to the second communication apparatus. The first communication apparatus moreover comprises training mechanisms for generating a training code to be sent to the second communication apparatus enabling a receiver to match a received signal to a corresponding transmitted signal. According to the invention, a training code is used with at least nearly ideal cyclic auto-correlation properties such that its cyclic auto-correction function is at least nearly zero for all cyclic shifts. The transmitter concurrently sends a training code in a mutually shifted manner, while the receiver is capable of performing a cyclic auto-correlation with respect to a received training signal.

Abstract: A monitor for monitoring the operation of a scheduler for controlling the departure of data cells is provided, comprising a detector for detecting the state of an internal element of the scheduler during a test, and determining means for determining whether the scheduler is operating as intended based on the detected state of the internal element.

Abstract: A method of mapping between contexts of a packet network and TDM channels and streams. The method comprises constructing a lookup table defining the sequence in which data is to be mapped between contexts and TDM channels and streams, and including for each row of the table a flag which indicates whether or not that entry is the first entry in the table for the corresponding context. As the TDM receive or transmit entity cycles through the lookup table, use is made of the flags to synchronize the start of each packet with the first entry of a TDM frame for each context.

Abstract: An inter-network relay unit is provided that is capable of simultaneously achieving guaranteed minimum bandwidth and priority control (including relay priority, discard priority, delay priority, etc.). A rate controller outputs relatively high priority packets from priority queues as guaranteed traffic based on guaranteed bandwidth for each link. Relatively low priority packets left in the priority queues are marked for preferential discard and output as best-effort traffic by an aging timer. When an output port is congested, an output queue portion discards only the marked packets. Thus, traffic having a plurality of relay priorities can use the guaranteed minimum bandwidth effectively and the guaranteed minimum bandwidth can be secured, irrespective of change in traffic volume for each relay priority level.

Abstract: A communications system that provides broadband access to passengers of mobile platforms includes a router located on the mobile platform. A network is connected to the router. User communication devices (UCDs) connected to the network, wherein the UCDs establish point-to-point over Ethernet (PPPoE) sessions with the router. A transmitter and a receiver are connected to the router. A satellite and a ground station are in communication with the transmitter and the receiver. A distributed communications system includes virtual private networks (VPN) and is connected to the ground station. A first address manager leases the use of public IP addresses by the mobile platform. A second address manager assigns the public IP addresses to UCDs when the UCDs request access to the VPNs and private IP addresses for other network service. The UCDs employ IPSec protocol when accessing the VPNs.

Abstract: A method for communicating across divergent network segments in a network. The network has a first network segment and a second network segment. The first network segment includes a switch that is controlled by a module that has instructions encoding a method. In the method, an ARP request packet is received from a first device. The ARP request packet includes a request to locate a second device. The first device is coupled to the first network segment and the second device is coupled to the second network segment. The ARP request packet is broadcast to the network segments outside of the first network segment and, as a result, a reply from the second network segment is received. The reply is transmitted to the first device, such that in use, ARP tables are modified on the first device and the second device so that future communication between said first device and said second device is enabled using a layer two communication protocol without any requirement for a layer three communication protocol.

Abstract: A telecommunications transport network is described in which a plurality of network elements each has a performance monitoring facility operative to report overall error rate at the element in each network path using the element. The network includes one or more management systems operative to calculate performance of a segment of a path between two network elements, from the reported overall error rates at the elements. Monitoring can thus be provided in management software using standard interfaces to gather the reported error rates, without additional ASICs at the network elements. Since not all paths will require TCM the additional processing required by the network management systems need not be great. Not even every connection that crosses a domain boundary will necessarily need TCM although the facility is especially useful for dedicated connections.

Abstract: Methods and systems for matching the communication protocol of a calling device with one of a plurality of communication protocols supported by an answering device are provided. Initially, a predetermined amount of data is received and buffered in a memory component. Following, an analysis is performed to match the received data with one of the communication protocols supported by the answering device. Communication protocols that can be detected and matched include, for example, the V.110, V.120 and ISDN protocols. During the buffering and analyzing steps, a predetermined data pattern such as mark idle can be transmitted to the calling device. Thereafter, the answering device is configured to answer the call according to the protocol matched in the analyzing step. A timer can be utilized to limit the period for matching to a predetermined length, after which time the answering device can be configured to answer the call in analog mode.

Abstract: A QoS scheduler, scheduling method, and computer program product are provided for implementing Quality-of-Service (QoS) scheduling with detecting and anticipating the end of a chain of flows. A first indicator is provided for indicating a number of flows being chained to a physical entry. A second indicator is provided for indicating when the first indicator has saturated. The second indicator is set active for a flow whose chaining causes the first indicator to saturate. During de-chaining of the flows from the physical entry, the second indicator is used to determine when the first indicator becomes accurate to begin decrementing the first indicator. The first indicator is decremented for detecting the end of the chain of flows. Responsive to the first indicator being not saturated, the first indicator is used for anticipating the end of a chain of flows. The first indicator and the second indicator include a predefined number of bits or n-bits.
