    Abstract: In a communication system, the individual processes of call establishment and control (call model elements) much as call authorisation, call set up, service control and call termination, are distributed over a plurality of network nodes. Each node is capable of handling one or more call model elements. Before a call is processed, the call model elements are assigned to a plurality of nodes according to node availability and capability. If a particular node becomes faulty during a call, the call model element assigned to that node can be reassigned to a different node before it becomes active. In this way elements are dynamically and flexibly allocated to nodes so that sensitivity to single point node failures is decreased. Elements can be reassigned according to an algorithm to minimise access delays or traffic queues. The network nodes may be geographically distributed among a plurality of sites.

    Abstract: A dispatch trunked radio system which provides duplex or simplex telephone interconnect communications to subscriber units. The system allows duplex capable trunked system subscriber units (102), (104) to establish a full duplex communication link with conventional land based telephone interconnect service in accordance with a method which unifies the operation of the trunked system subscriber units (102), (104), a plurality of trunk system repeaters (106), a trunked system central control unit (110), and a telephone interconnect control unit (352). The method of the present invention also provides improved trunked system performance by allowing simultaneous transmission and reception of channel controlling information.
