A wireless telecommunications system is provided for connecting to a data link and for routing data packets between the data link and a subscriber terminal. The wireless telecommunications system provides a group of communication channels arranged to utilise a radio resource. The group is shared by a plurality of subscriber terminals. A subscriber controller within the subscriber terminal is arranged, when a data packet is to be transmitted to the data link, to acquire a communication channel from the group to enable that data packet to be transmitted. A resource monitor is then used to receive information concerning traffic loading, and to apply predetermined criteria to determine how long the communication channel may be acquired for by the subscriber terminal before causing the subscriber controller to release the communication channel.

Transfer of data packets in a wireless telecommunications system

Management of a telecommunications system

Methods and systems for telecommunications terminals management that include at least one telecommunications terminal and an attached computer. The telecommunications terminal generates messages describing the telecommunications terminal (e.g. card insertion or removal and terminal alarms) either autonomously or in response to automatically generated requests. The computer processes these messages to build a model of connected telecommunications terminals. The model can be a hierarchy of software objects where objects are inserted and modified based on the message produced by the telecommunications terminal. The computer can display the model information to an administrator. The administrator can interact with the model to alter properties of the telecommunications terminals represented.

Telecommunications terminals management

The present invention provides a wireless telecommunications system comprising an interface mechanism for establishing a wireless link between a central terminal and a subscriber terminal within said wireless telecommunications system. The interface mechanism comprises a radio port manager within the central terminal for configuring the central terminal to receive an acquisition request message from a subscriber terminal on a radio slot associated with the radio port manager, and a radio port slave within the subscriber terminal for receiving an invitation message inviting the subscriber terminal to acquire the wireless link on said radio slot, and for issuing the acquisition request message to said radio port manager. The radio port manager is responsive to receiving the acquisition request message to grant the subscriber terminal access to the radio slot.

Establishing a wireless link between a central terminal and a subscriber terminal of a wireless telecommunications system

A communications protocol interface is arranged at a central station of a telecommunications network and is responsive to a control message received from a network controller in accordance with a first message protocol to transmit the control message in accordance with a second message protocol to subscriber stations and is responsive to a control message received in accordance with the second message protocol to transmit the control message to the network controller in accordance with the first message protocol. The first message protocol is a balanced protocol with the communications protocol converter or the network controller able to initiate an exchange of information. The second message protocol is a master-slave protocol with the communications protocol interface acting as master. The second control message protocol operates over central station bus for communicating with at least one network element in the central station.

Control message transmission in telecommunications systems

The present invention provides a system for handling telecommunications signals passed between a first and second element of a telecommunications network, the first element having an interface for transmitting and receiving signals in a first protocol, and the second element having an interface for transmitting and receiving signals in a second protocol. The system of the present invention comprises a first interface unit for receiving a first telecommunications signal transmitted in one of said first and second protocols between said first and second elements, the first interface unit being arranged to separate traffic bearing channels from non-traffic bearing channels within the first telecommunications signal. A traffic management element is then provided for performing a cross-connection function to map the traffic bearing channels to the appropriate format for the other of said protocols, whilst a protocol conversion element is provided for performing predetermined protocol conversion steps on the non-traffic bearing channels in order to regenerate those non-traffic bearing channels in the other of said protocols. Further, a second interface unit is provided for combining the channels as output by the traffic management element and the protocol conversion element in order to create a second telecommunications signal in the other of said protocols, the second interface unit being arranged to output the second telecommunications signal. Preferably, said first protocol has a concentrated format, and said second protocol has an unconcentrated format.

Handling of telecommunications signals passed between elements of a telecommunications network

A wireless telecommunications systems (,) includes a central terminal (,) for transmitting and receiving radio frequency signals to and from a subscriber terminal (,). A downlink communication path is established from a transmitter (,) of the central terminal (,) to a receiver (,) of the subscriber terminal (,). A downlink signal (,) is transmitted from the transmitter (,) to the receiver (,) during setup and operation of the wireless telecommunications system (,). The receiver (,) of the subscriber terminal (,) compares a code and phase of a master code sequence that includes an orthogonal code in the downlink signal (,) to a code and phase of a slave code sequence of the receiver (,). The receiver (,) adjusts the phase of the slave code sequence until a match is obtained with the master code sequence. The receiver (,) monitors the downlink signal (,) to identify the frame alignment signal (,) and establishes the downlink communication path when two successive frame alignment signals (,) are identified. A channel identifier signal within the downlink signal is identified and used to identify the orthogonal code included in the master code sequence. The channel identifier signal is matched to a reference identifier code to verify that the correct downlink signal is being read.

Apparatus and method of establishing and maintaining communication paths in a wireless telecommunications system

The present invention provides a wireless telecommunications system comprising an interface mechanism for allocating a radio slot for a wireless link between a central terminal and a subscriber terminal within said wireless telecommunications system.

The interface mechanism comprises a radio manager, responsive to an indiction that a call is to be established, for issuing an allocation request message to a radio slave within the central terminal requesting that radio slave to allocate a radio slot for the call. Further, a radio slave, associated with a frequency channel, is provided to be responsive to receipt of the allocation request message from the radio manager, to reference a record identifying available radio slots within the frequency channel in order to select, if available, a radio slot within that frequency channel for allocation to the call, and to issue a response message to the radio manager indicating that a radio slot has been selected.
