A method of allocating radio channels, between the base stations of a multi-base station radio system uses a, mathematical model of the radio system which is derived from an analog of the radio system. The analog is a thermal bath containing a plurality of interacting particles, each particle in a particular spin state. The number of particles at a given location in the thermal bath, corresponding to the traffic demand at an equivalent location in the radio system each occupied, spin state corresponding to the particular radio channel. The model is operated by allowing the spin states to relax, by means of a stochastic reduction in temperature of the thermal bath, from an initial infinite …

Why it's free to use
- Filed March 15, 1993 and granted January 21, 1997. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 15, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 15, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
