Traffic congestion often occurs on highways and results in a heavy call traffic load that impairs the performance of Dynamic Channel Assignment (DCA) strategies. We therefore propose a channel framework in which all the available channels are divided into two subsets according to the directions in which the mobile stations move. The decision of the division ratio depends on the offered load of each direction. We investigate, through simulations, DCA performances with channel framework for one-sided and both-sided traffic congestion and we compare these performances with that of DCA without the framework. We show that the channel framework increases call blocking but considerably reduces the occurrence of forced call termination and of channel changing during a call.
