Dynamic channel assignment in a DQDB MAN based PCN access network

This paper considers a PCN architecture based on the DQDB MAN for implementing distributed control of resource allocation in mobile communications systems. In particular the paper considers dynamic resource allocation (DCA) strategies based on the distributed MAN architecture which may be implemented at a rate fast enough to accommodate statistical multiplexing on the air interface at the talkspurt level. A DCA strategy is proposed based on the interconnection of microcellular base stations by a hierarchical MAN topology. Performance estimates of the distributed DCA scheme are provided and comparisons made with a fixed channel allocation strategy.
