In a method of routing a call in a network with a plurality of nodes connected by trunks, each call is assigned a priority level as a function of which it can pre-empt calls in the network. The cost of different routes for routing the call is calculated and one route is chosen as a function of the cost. The cost of a route is a function of the maximum value on the trunks constituting the route, the priority level of the calls pre-empted on each of the trunks, the number of calls pre-empted on the trunks and the resources available on the trunks. The priority level of existing calls can therefore be taken into account when routing a call. The single figure of the accompanying drawing shows the typical trend of the cost function of a trunk as a function of the available resources. |
