A communications system allocates communication bandwidth to calls in such a manner for optimizing network system performance. The system uses knowledge about the state of the past and present network demand, and network resources. Predictions of future demand and future network resources are used to calculate future network performance. Allocation decisions are chosen based on network performance calculations and probabilities of achieving future network states.

[ What is claimed is:] [1.] A communications system, comprising:a ground node receiving calls; anda control unit maximizing a communication system expected utility function and allocating communication resources to received calls based on the communication system expected utility function;wherein, preferably, the control unit allocates communication system resources by performing at least one ofassigning communication resources to calls, the communication resources including communication bandwidth,blocking calls, andpreempting calls in progress; rein the control unit maximizes the expected utility function of the communication system byidentifying decisions relating to communication resource allocation, each decision d.sub.i being a different communication resource allocation decision;determining a maximum expected utility function E as: ]EQU4 ] wherein s.sub.j is a possible configuration of communication bandwidth assigned to individual calls,wherein C is a system context based on at least one of a present network state and a past network state,wherein p(s.sub.j .vertline.d.sub.j, C) represents a probability of achieving state s.sub.j given a decision d.sub.i and the system context C,wherein u(s.sub.j, d.sub.i) represents a utility function based on a weighted combination of network performance characteristics; andselecting the resource allocation decision d.sub.i that maximizes the expected utility E of the communication system.
