Abstract: A mobile station detects whether there is congestion in a cell by monitoring a first channel fix downlink messages and decoding the messages to see if the decoded messages indicate congestion, where the first channel is a common control channel (CCCH). For the case in which the mobile station determines from the decoded messages that there is no congestion, the mobile station initiates a random access procedure by transmitting a request message uplink on a random access channel (RACH). Else for the case in which the mobile station determines from the decoded messages that there is congestion, the mobile station waits for a waiting time before initiating a random access procedure.

Abstract: An apparatus, comprising at least one processor configured to receive and read a series of blocks on a first channel and determine whether there is congestion and if not transmitting a channel request on a second channel.

Abstract: According to the exemplary embodiments of the invention, there is a method, apparatus and computer program for composing at least one system information message instance for a first particular radio access technology system, and for transmitting the at least one message instance to at least one network node.

Abstract: An apparatus having a buffer store connected to an input line upon which ATM cells are received, and an output line upon which ATM cells are transmitted is provided. A control device receives, for each cell, a channel identifier and a path identifier from which a first signal is generated indicative of a maximum delay value which is applied to the buffer store and used to schedule the particular cell for transmission on a calendar controlling a sustainable cell rate. The control device generates a second signal indicative of a minimum delay value which is applied to the buffer and, in conjunction with the first signal, is used to schedule the particular cell for transmission on a calendar controlling the peak cell rate. The apparatus can also handle routing information, where a group of channel connections define a Route which share a peak cell rate for the Route and are scheduled on the peak cell rate calendar.

Abstract: An ATM communication system including an ATM switch having input and output ports is provided. Each input port is fed from an input port server and each of the output ports are arranged to feed an output port server. The input port servers include buffer stores, one for each of the output ports, to which data is transmitted through the switch. Each buffer store in the input port servers is arranged to interrogate the output ports server, with which it communicates before the transmission of data, to determine whether the output port server data handling capacity is available. The ATM communication system includes a transmitting devices for unicast traffic and multicast traffic. The transmitting device includes an output time slot control device and a scheduling device arranged to allocate a time slot for the transmission of each unicast traffic cell, and for calculating when a time slot is available for transmission of a multicast traffic cell.

Abstract: This invention relates to the efficient use of resources in broadband telecommunications networks when handling bursty data traffic. A new technique shapes the data traffic profile to efficiently maximize the bandwidth reservation scheme whilst minimizing data loss and delay. The Fast Bandwidth Reservation Shaper (FBRS) comprises a FIFO buffer with three thresholds (T1-T3), a server, and a Fast Reservation Protocol (FRP) control function which monitors the state of the queue and its associated thresholds, alters the service rate of the server, and handles the FRP protocol. With an empty buffer, a zero or small bandwidth is allocated to the data connection. When the first buffer threshold is reached, the FRP controller attempts to negotiate a small data rate (R1) with the network. As the queue grows to the second threshold (T2), the FRP controller attempts to negotiate a higher data rate (R2), slightly larger than the peak data rate for that traffic.

Abstract: An ATM communication system has an ATM switch having a plurality of input ports and a plurality of output ports, each of the input ports being fed from an input port server and each of the output ports being arranged to feed an output port server. The input port servers each have a plurality of buffer stores, one for each of the output ports to which output port data is transmitted through the switch. Each buffer store in the input port servers is arranged to interrogate the output port server with which it communicates by a bandwidth request before the transmission of data. This determines whether output port server data handling capacity is available, whereby ATM switch operation during periods of peak traffic is facilitated. The system includes a queuing arrangement for bandwidth requests received during periods when there is no available bandwidth capacity, the arrangement being such that requests are released in a predetermined order when capacity becomes available.

Abstract: An ATM signal processor system for processing ATM data cells which in combination define a data package wherein the last cell of a package is characterized by an identifying code. The cells of different data packages are multiplexed to provide a serial data stream. A server and a buffer store via which the server is fed with the serial data stream are provided. The buffer store has a threshold capacity beyond which cells are discarded. A discarded cell identifier/rejecter serves to identify and store the identity of a data package with which a discarded cell is associated so as to be set thereafter to reject subsequently received cells with the same data package identity until being reset upon receipt of the last cell of the package as indicated by its characteristic identifying code.

Abstract: A multicast server apparatus operative to effect the onward transmission of data cells to a plurality of different addresses includes a switch function unit having an input port, an output port and a transfer port, data cells for multicasting being routed from the input port and to the transfer port, first and second header translation units each having an input terminal and an output terminal. The translation units serve respectively as a chainer and as a distributor, the input terminals of the chainer and the distributor being coupled to the transfer port of the switch function unit to receive data for multicasting. The chainer is effective to change address data associated with each data cell fed thereto to a form recognizable by the distributor and to feed back such data cell together with its changed address data to the transfer port.
