Abstract: The Invention provides a distributed resource allocation Method. The distributed resource allocation method is based on the concept of proportional fairness. In this method, users express their willingnesses to pay to the local distributed controller which is associated with those users. The bandwidth allocated to each user is determined by the local controller with which they are associated and the allocation takes into account the relative demands on all the resources in the network and the time taken for those demands to reach the distributed local controllers. The distributed controllers each use only locally available information at their respective nodes, but take into account the delays between nodes. The locally available resource (i.e. bandwidth) is divided in proportion to the willingnesses to pay expressed by the various users entering their particular node.

Abstract: A method is described of controlling a communication system using a continuous FDD channel. Each time segment of the channel is divided into a predetermined number of sub-segments. For a first set of time segments, the communication signal data for the respective time segment is repeated in all sub-segments, and for a second set of time segments, null periods are provided in one or more of the sub-segments during which the communication signal from the first station to the second station is interrupted. The communication signal data is transmitted during the remaining sub-segments of the second set. This approach enables a slotted transmission mode to be established in a CDMA FDD system, without the need to adapt the spreading ratio of the CDMA system.

Abstract: The present invention relates to a method for improving service level selection in a communication network system, in which an interworking function (IWF) is arranged between a user terminal (MS) and the network(s) in question, and wherein High Speed Circuit Data (HSCD) are specified, and for the purpose of making this selection in a more expedient manner and allow the user to allocate bandwidth in a more flexible and dynamic way, it is according to the present invention suggested that the interworking function (IWF) is used for signalling to the user terminal (MS) when a change in level selection may be useful.

Abstract: A digital trunk circuit supporting multiple trunk circuits assembled in a single board. A trunk selector capable of being operated by a user, outputs trunk select information for selecting one of the multiple trunk circuits according to an operation of the user. A read only memory (ROM) stores drive programs for the respective trunk circuits. A framer and line interface serves as a T1 framer or an E1 framer according to a register value, and includes line interface nodes having a connection for the T1 framer or the E1 framer. A receiving transformer connected to an office line, receives a signal incoming from the office line. A transmission transformer connected to the office line, transmits a signal to the office line.

Abstract: The invention provides a resource allocation method which is based on the concept of proportional fairness. In this method, users express their willingnesses to pay for network resources. A controller determines how the users' willingnesses to pay are to be divided between the resources in order to determine the relative demands for the resources. Each resource is then divided between those users using it in proportion to how much they are willing to pay for the use of their share of it. The allocation takes into account the relative demands on all the resources in the network. A user may increase his share of the network resources allocated to him by increasing the value of his willingness to pay. The method may be applied either by a central controller (network manager), or it may be delegated to controllers (network element managers/customer premises equipment managers) distributed across the network.

Abstract: An asynchronous transfer mode adaptation layer switching network has independent call routing and connection control for setting up connections across the system. A plurality of adaptation layer switches (ALS) coupled to the ATM network comprise a group adapted to function as an adaptation layer switching network whose fabric and control are distributed over the group. The network having means for determining its current system status whereby to set up multimedia calls across the network based on that status determination.

Abstract: A communications network arranged to provide multimedia switched services comprising a set of media components. The set of media components including IP traffic is encapsulated in an ATM virtual circuit and is switched as an entity using a robust signalling system so that the resultant connection records can then be employed for usage based tariffing purposes. This overcomes the problem of establishing billing records for connectionless traffic carried over a connection oriented network.
