After every two cycles also the rate error of the local clocks can be ascertained and a suitable correction value determined. The reliability of safety-relevant networks is increased by the time-triggered communication system described hereinabove.

Abstract: An unique arrangement including a so-called timing control order and timing control signals is employed to identify whether wireless terminals are reachable within a base station cell coverage area in a wireless communications system. To this end, detection of a particular wireless terminal being alive and well, and within the cell coverage area associated with a base station is effected by the base station transmitting a timing control order in a timing control time slot reserved for the particular wireless terminal.

If the base station does not receive the timing control message, it is an indication that communication with the particular wireless terminal has been lost.

Abstract: The present invention provides a novel method for transferring SCCP messages to one of a plurality of entities in an entity set. The method receives a SCCP message from which a traffic type for said received message is determined. A global title associated with said received message is then translated to a destination entity set. For each entity in the destination entity set, a maximum allowed rate for receiving messages of said traffic type at that entity and a current rate for transferring messages of said traffic type to that entity are determined. The method then determines a subset of entities for which the current rate is smaller than or equal to the maximum allowed rate. If the subset contains at least one entity, the method selects one entity from the subset and transfers the SCCP message to said selected entity. The invention also provides an advanced signaling transfer point STP.

Abstract: A method and apparatus for an improved Multiprotocol Label Switching (MPLS) system for traffic engineering is described. The improved MPLS system determines the actual traffic flow within a traffic engineering (TE) tunnel and dynamically adjusts the bandwidth to reflect the actual traffic flow. The actual traffic flow may be ascertained by accessing an average byte counter, which keeps track of the traffic flowing through the TE tunnel. Once the actual traffic flow is known the bandwidth is updated in accordance with the actual traffic flow. This allows the MPLS system to automatically maximize the bandwidth resources while minimizing operator intervention.

At each row/column nexus, the transmit/receive matrix includes an entry which indicates whether communications are to be effected between a pair of terminals that corresponds thereto. Slots in the control data frame are then allocated to pairs of the plural terminals based on these entries in the transmit/receive matrix.

A status associated with the first bit stream is queried. In response to the query, status information, which includes a configuration map status, is received for the first bit stream. The configuration map status for the first bit stream is then stored in a first memory area. A command is received for disconnecting the first bit stream on the first channel from the second channel, and the first channel is disconnected from the second channel.

A command is received for connecting a second bit stream on the first channel to a third channel. A configuration status for the second bit stream is stored in a second memory area.

Abstract: The system separates the common administrative functions from the supervisory host applications. Each administrative function is performed by a separate administrative process that is dedicated to that function and is accessible by all the supervisory application. Thus when a supervisory process requires performance of an administrative function, it invokes operation of the corresponding administrative process. With this arrangement, only a single copy of each administrative process needs to be maintained. All communications between the administrative processes, the switching platform and/or the supervisory applications are routed through a gateway process. The gateway process then forwards the message to the appropriate process or switch and later returns the any reply results to the requesting process or application.

Duplicate modules of the data switching fabric receive identical packets and, when synchronized, transmit identical packets at the same time. The synchronization process is implemented by data links between the control processors of the duplicate fabrics to report progress on the step by step synchronization of internal queues.
